Climate Change: losing sight of the real target.

[this article was originally published on We thank the author Bob. S. Effendi]

In September 2015, German Environment Minister Barbara Hendricks made a statement which shock the world, Germany is likely to fail its 2020 emission reduction target which fall short by seven percent [i].

How could this be, to a Climate Change champion with its 520 Billion Euro Energiewende Program which aim to make German energy mix 80% by clean energy, that is mostly wind and solar by 2050.

As its stand by 2015 Germany’s renewable already up to 30% of the total energy mix, probably the largest renewable energy mix in the world. But the irony is with all that renewable how could Germany predicted to miss the emission reduction target? Isn’t the premise to increase renewable shares so that to reduce CO2 emission.

It turns out that German electricity is consider among the dirtiest in Europe not only that but to make thing much worse in the past 5 years after the implementation of Energiewende, German electricity tariff has double making it the most expensive in Europe and is not affordable to some German.

According to Eva Bulling-Schröter, energy spokeswoman for Die Linke, Germany left party, between 2011 and 2015, about 300,000 German homes get their power cut off because they can no longer afford to pay their bills [ii].

McKinsey just release a 20 pages report on German Energiewende which was featured in Die Weld, a German National Newspaper, that Energiewende does not achieve its goal in reducing emission and it has put burden on the economy but despite these obvious facts German Government refuses to acknowledge that their energy policy has become a dismal failure [iii]. Basically, what McKinsey is saying that Energiewende is a 500 Billion Euro disaster.

The fact of the matter, Germany does not make it into the 10 cleanest electricity in Europe according to real-time map which measure CO2 intensity ( created as an open source project by Tomorrow, a Climate Change concern organization. Germany CO2 intensity is runs around 350–450 gram CO2/kwh whereas Norway at no 1 (8 gram), Sweden at no 3 (37 gram), Switzerland at no 4 (63 gram) and France at no 5 (66 gram) [iv].


According to Massachusetts institute of Technology study even if the whole signatories of Paris Accord do everything what they pledge to do, it will only result in a slight reduction in global temperatures of just 0.2°C by 2100, global temperature will still raise to 3.1–5.0 degree to pre-industrial level. [v]

According to the study to meet the target, deeper cut on fossil need to happen. Which is obvious that a lot of these countries are not willing to give-up fossil as a dependable cheap economic driver and has become a strong industry with far reaching political influence but instead focusing on renewable. This should make you rethink maybe the world has lost sight what the real target is? Is the Paris Accord is really about climate change or something else?

It’s a simple question, if the objective of climate change is carbon reduction, then what should be the measuring stick then, is it: a) How much renewable energy you put or b) How much CO2 is in your electricity.

It’s a no brainer, off course is how much CO2 in your electricity (CO2/kwh) or how much CO2 per energy per capita (CO2/capita). Germany has shown that the more renewable you put does not relate to reduction of CO2 emission in fact it has the opposite effect which is as also shown in California.

Even in California where strict environmental and climate legislation has been enforced for many years and has the highest renewable mix in the US, but with all those effort it still is fail to reduce its emission and increases the electricity tariff which makes California electricity become the most expensive in the US [vi].

Ron Kirk, US Trade Representative, Clean and Safe Energy Coalition co-Chairman and former Mayor of Dallas put it bluntly “The more you put renewable the higher your emission and so is your electric bill as proven by Germany and California” [vii].

What Germany and California has proven is that you cannot make intermittent renewable, such as wind and solar as primary energy because of several reasons: 1) its low energy density thus requiring huge amount land and 2) can only deliver at best less than 25% of capacity thus at the end require a fossil backup 3) its intermittent nature, creates a problem to grid making the gird unreliable thus maintaining a reliable electricity service become costly for utility.

With that in mind, we should not lose sight of what is the real target, obviously not renewable but carbon reduction and the measuring stick should be CO2 intensity or CO2 per capita not renewable and to achieve that there is only one way to do it that is replacing all fossil especially coal as primary energy with another zero-emission energy source which can act as base load meaning operating 24/7.

It’s a simple formula, your primary energy mix should be more than 65% zero carbon energy, It’s either Hydro or Nuclear or combination. With Norway its 97% Hydro, or with France its 79% Nuclear or combination of the two like Sweden with Hydro 36% and Nuclear 35%.

It is a simple fact that without combination of these two form of energy there is no way you could achieve a decarbonization economy, it is not a theory but it is an indisputable fact. In fact, Nuclear produces more than 60% of zero carbon electricity in the world.

So it is ridiculous for countries which committed to climate change but follow in the foot step of Germany by closing down its nuclear power plant, such as Switzerland [viii]. The fact is that Nuclear was never on table or discuss in any UNFCC document. Even in the latest UN Deputy Secretary General speech on The Goal of Climate Change, there is a lot of mention of clean energy, a lot mention of wind and solar but no nuclear. Is Nuclear not a clean energy? [ix]

So in the end, if the discussion on climate change does not include Nuclear on the table then the Billion Dollar Question is: are they seriously want to fight climate change or just being anti-nuclear ?.

Accident at Hanford

[this article was originally published on We thank the author and the editors.]

News wires have been buzzing about a tunnel cave-in at the Hanford nuclear facility in Washington State. The Hanford facility is extremely large, 580-square miles, or about half the size of the state of Rhode Island. It produced the plutonium used in the bomb dropped on Nagasaki, and during the cold war facilities were greatly expanded for weapons production. The last reactor at Hanford was shut down in 1987, and decommissioning and cleanup operations have been ongoing since 1989. The site has been fraught with problems stemming from the storage of radioactive waste, and because of the risk of releases of radioactive material to the environment, particularly the nearby Columbia River,  it is closely watched by environmental groups.

The accident yesterday involved the collapse of a small (20 x 20 foot) section of a storage tunnel built as part of the Plutonium Uranium Extraction Facility (PUREX), detected by workers on the morning of May 9th. These tunnels, constructed in the 1950’s and 1960’s, hold rail cars loaded with contaminated discarded equipment. They were constructed of wood and concrete and covered with approximately 8 feet of soil. The collapse is probably due to the degradation of wood used in construction.

Because the Hanford site is so large, only very large radioactive releases can be detected off site. This makes it difficult if not impossible to verify official data regarding releases. Official reports so far have indicated that no airborne releases of radiation have been detected due to the tunnel collapse. Nevertheless, an emergency was declared, and personnel were evacuated from nearby areas of the site and required to shelter indoors in others. As of 8pm on May 9th, work had begun to stabilize and fill the opening of the collapsed section.

Cheryl Rofer, formerly of the Los Alamos National Laboratory, posted an informative blog at Nuclear Diner, in which she concluded that the risk of large releases due to this accident are small.

At the same time, the tunnel collapse should call attention to the greater risks posed by deteriorating infrastructure at Hanford. The Washington Post notes:

“An August 2015 report by Vanderbilt University’s civil and environmental engineering department said the PUREX facility and the two tunnels had “the potential for significant on-site consequences” and that “various pieces of dangerous debris and equipment containing or contaminated with dangerous/mixed waste” had been placed inside the tunnels.”

(Update) Our colleagues at the NRDC communicated the following to us:

— NRDC assessment is that this accident does not pose a risk off site but will create increased risk for Hanford Site workers dealing with the accident, with substantial increased cleanup costs;
— This accident illustrates the difficulty of the cleanup of the US Cold War legacy of nuclear weapons production — the largest environmental cleanup project in the world costing over $6B a year (nearly $2 billion per year alone at Hanford) – every nation that has made nuclear weapons has hurt its own people and natural environment in the process – it further illustrates some complicated regulatory problems (lack of EPA and State authority over the site, where NRDC has long pushed for transparency).
— Continued risk at Hanford is greatest from the 56 million gallons of toxic, liquid high level-radioactive waste held in 177 very large tanks some of which are leaking – this underground plume threatens the Columbia River.

To summarize, this particular accident appears to be quite small and localized, but that may just be luck. In this instance, Safecast is concerned about the lack of independent monitoring at the Hanford site to confirm official statements about radiation releases.

Iodine-131 Over Europe: Probably Medical

In early January, slightly elevated levels of iodine-131 were observed over northern and western Europe. The levels were measured during a temperature inversion, along with elevated levels of naturally occurring radioisotopes.

This, along with the deployment of an American WC-135 aircraft to the Mildenhall Royal Air Force Base in the UK, has led to speculation that the Russians have carried out a nuclear test. This is highly unlikely for several reasons.

No, radiation levels at Fukushima Daiichi are not rising

[this article was originally published on We thank the author and the editors.]

This grating inside Daiichi Unit 2 was likely melted by falling fuel debris (TEPCO photo)


— Yes, TEPCO has measured very high radiation inside Daichi Unit 2.

— No, it does’t mean radiation levels there are rising.

In response to visual investigation results and high radiation measurements recently taken by TEPCO inside Fukushima Daiichi Unit 2, many news outlets have published stories with headlines like “Fukushima nuclear reactor radiation at highest level since 2011 meltdown.” (The Guardian, Feb. 3, 2017).

This has led to a number of alarming stories claiming that radiation at Daiichi has “spiked” to unprecedented levels. That’s not what the findings indicate, however. In addition, Safecast’s own measurements, including our Pointcast realtime detector system have shown radiation levels near Daiichi to be steadily declining. As described in the Safecast Report, Vol.2, Section 2.1.4, TEPCO and its research partners have been developing robots and remote visualization devices to search for melted fuel debris deep inside the Daiichi reactor units, and to help plan for its eventual removal. On January 30th, 2017, a long telescoping device with a camera and radiation measurement device attached was inserted through an existing opening in the reactor containment of Unit 2 for the first time, and successfully extended approximately 8 meters into in an area known as the “pedestal,” to measure and take images from immediately below the damaged reactor pressure vessel (RPV). In addition to finding the area covered with molten material likely to be fuel debris, radiation levels of 530 Sieverts per hour were detected, which would be fatal to a person exposed for only a few seconds.

The recent investigation used existing openings in the Unit 2 reactor to obtain images an measurements inside the pedestal area.(TEPCO image)

The telescoping arm (in yellow) was designed to reach inside the pedestal area to obtain visual imagery and radiation measurements.(TEPCO image)

It must be stressed that radiation in this area has not been measured before, and it was expected to be extremely high. While 530 Sv/hr is the highest measured so far at Fukushima Daiichi, it does not mean that levels there are rising, but that a previously unmeasurable high-radiation area has finally been measured. Similar remote investigations are being planned for Daiichi Units 1 and 3. We should not be surprised if even higher radiation levels are found there, but only actual measurements will tell. Unit 4 was defuelled at the time of the accident, and though the reactor building exploded and the spent fuel pool was dangerously exposed, it did not suffer a meltdown, so similar investigations are not being conducted.

Under a consortium called IRID, TEPCO and its research partners have been developing robots and other devices to assist in investigations inside the damaged reactors, where radiation levels are too high to allow humans to safely enter. The recent investigations at Unit 2 were intended to help plan the travel path of a folding crawler robot called the “Scorpion.” This device is designed to crawl around on the metal grating deck inside the pedestal and gather further imagery and measurements. The recent investigations, however, have revealed a 1×1 meter section of the deck to be melted through, and much of the rest may be impassable for the robot. In addition, the high radiation levels will likely limit the amount of time the robot will be able to operate before malfunctioning to about 2 hours, instead of the planned 10 hours. Much more melted fuel debris is assumed to have settled beneath the pedestal grating on the concrete basemat of the reactor. It was hoped that the Scorpion would be able to provide imagery of this. Not surprisingly, TEPCO is once again revising its plans based on the recent findings. These investigations are technically quite impressive, but they have already been delayed for over a year due to the need to more adequately decontaminate the area where human workers must operate and to solve other technical problems. This recent imagery is extremely informative and helpful, and had been eagerly awaited by many concerned people, including Safecast. If nothing else, we have learned to be patient as TEPCO proceeds slowly and cautiously with this work.  The process of removing melted fuel debris from the damaged reactors at Fukushima Daiichi is expected to take decades, and these recent findings remind us once again that TEPCO has little grounds for optimism about the challenges of this massive and technically unprecedented project.

Making America great again

Bellefonte NPP, started in 1974, abandoned in 1988, will it be completed?
Bellefonte NPP, started in 1974, abandoned in 1988, will it be completed?

In our honest opinion there is a man who is already doing it! His name is Franklin L. Haney and he is 75 years old.

This Chattanooga, Tennessee-based mogul picked up a nuclear power station in Hollywood, Alabama at an auction last week. Yes, you read well, a nuclear power station, for just 111 million dollars! That’s the famous never completed Bellefonte.

As reported by CGR (Global Construction Review) online magazine, Haney said “the rejuvenated plant would ‘transform communities’ hit by coal-plant closures in Alabama and Tennessee.” And “completing the plant will employ up to 4.000 people; while operating it would create 2.000 ‘permanent, high paying jobs’.”

But he will need to bring all his deal-making talents to bear on this new asset: construction of the 2,6 GW power station was halted in far 1988 and it is likely to request several billion dollars to get it completed, because unit 1 is deemed approximately 55% complete, and unit 2 approximately 35% complete, having for years been ransacked for spare parts.

In addition, to hold him to his promises regarding the site, the seller, state utility Tennessee Valley Authority (TVA), stipulated that the buyer must invest at least 25 million dollars on the property within 5 years of closing the deal.

Well, imagine our shock, if this won’t happen!

We mean, we aren’t sufficiently oriented to wishful thinking about nuclear power to forget that business is business. And Mr Haney could always change his mind, provided he hasn’t already now (in a drawer somewhere) a different idea from that he has shown so far.

But let’s still dream for a while, with Haney’s words. “Today marks the first step of an exciting new journey for the people of Alabama and Tennessee,” he said in a statement. “The Bellefonte Nuclear Station will help transform communities across the region. This project will bring new life to the region by creating thousands of jobs while providing assured access to reliable, affordable, zero-emission energy.”

How not to agree?

Surprisingly this words match with some (not all) statements heard during the last presidential election campaign, about which we are standing with high hopes!

Hey, don’t take this as a galvanized reaction to the the news of November 9th, 2016. U.S. President-elected Donald J. Trump has still to demonstrate to be really ready and willing for a new cursus of energy policies, and only History will tell us if this shall be also in favor of a new nuclear renaissance for America.

And by the way, it’s hard to miss the fact that Mr Haney, a long time Democratic donor, funded the campaign for President Obama’s reelection 4 years ago. Not to say he has also been several times under reflectors due to the fact he has built his business around developing government-supported real estate projects – being even indicated as a “Government Landlord”.

And so on and on, you can find by yourselves a lot of interesting further information or silly yak-yak on the web. This is not the point.

We were simply wondering if Haney’s iniziative in coincidence of Trump’s election could be a symptom of a new sight on America’s energy future. In other words, if such a kind of investment is a claim of “innovative financing”; if it will possibly suggest some good ideas to the President-elected; and ultimately if it can really change the approach to nuclear power in the U.S. and, as a reflection, all over the World – maybe a tangible way to make America great again.

Well, our guess and hope is: yes, yes and yes!


11/25/2016 Update: Maria Korsnick, CEO of the Nuclear Energy Institute, has recently discussed about the future of the American nuclear industry under Trump administration. You can watch the video of the interview at this link.


Comparing nuclear power plants and wind farms resilience to hurricanes

Hurricane Matthew affected the continental US last week, the first since 2005. It was a category 5 hurricane that caused more than 1000 deaths, mostly in Haiti, and about 7 billion dollars damage as a preliminary estimate.

As Matthew quickly moved toward Florida and the Carolinas, rigorous procedures to ensure safe operations of nuclear power plants in the affected areas were implemented.

Four NPP are located within the affected area: St. Lucie (FL), Robinson (SC), Harris and Brunswick (NC), for an overall capacity of about 5600 MW.

Previous hurricanes have shown that NPP are robust facilities able to withstand strong hurricane winds and storm surge [1], nevertheless the “unusual event” status – the lowest NRC’s emergency condition- was declared for all the plants [2].

The plant personnel made sure that all the equipment potentially affected by heavy wind and rain were secured and a “walkdown” inspection through the plants response to disaster condition was initiated, including assessing the availability of emergency diesel power generators for at least a week.

When Matthew made landfall in South Carolina, early on Saturday, Robinson plant safely shut down due to loss of power and flooding of transformers. Harris suffered power outage too, but was already shut down for scheduled refueling. Brunswick was instead fully operational but was required to modulate down to 50% capacity on Sunday in order to respond to reduced capacity of the grid. By Wednesday all nuclear plants exited their “unusual event” status and, after routine safety inspections, ramped back to full capacity.

Wind power is the fastest growing renewable source in the US. According to DOE scenarios of 20% wind power in the US by 2030 (2008, [3]), offshore wind should contribute with 54 GW. Most of this power should come from shallow to intermediate depth farms along the Atlantic coast, that has a potential capacity of 920 GW and the Gulf region, with a potential capacity of 460 GW [4]. Incidentally, those regions are the preferred hurricanes corridors! Regardless the accuracy of these estimates and the feasibility of the envisioned goals, how would the wind farms stand a hurricane?

In August 2003, the typhoon Dujuan hit the southern part of China and caused severe damage to a wind farm located in the coastal area of the Guangdong province. The wind turbines were designed to survive a maximum gust of 70 m/s, but a maximum gust simultaneously with significant yaw error and rotor standstill had not been considered. The actual maximum gust did not exceed the design maximum gust of 70 m/s. Several wind vanes were damaged during the cyclone’s passage [5].

Few days later, typhoon Maemi almost flattened a wind farm on Miyakojima Island (Japan) [6].

Miyakojima Island 6 turbines wind farm after the passage of typhoon Maemi. Modified after [6].
While blades are relatively easy to replace, tower buckling is a severe damage that can require months to years for restoration [7].

At present there are no wind farms offshore the US East coast and in the Gulf of Mexico, but several are planned.

Thus a recent paper [7] estimated the resilience of offshore wind farms to storm conditions. Wind turbines are designed to operate with winds up to 25 m/s, over this threshold they shut down for safety reasons. The turbines currently on the market (Class 1) may (ideally, as Dujuan typhoon taught us) stand winds up to 70 m/s, but hurricane winds often exceed 80 m/s. Although the design of hurricane resilient turbines would be possible (Class S), this option comes with compromises on the productivity (i.e. they need stronger cut in wind to operate) besides higher costs [8].

Rose et al. (2012) [7] model both the risk from a single hurricane and the cumulative risk over the lifespan of a wind farm, through 4 sites offshore the Gulf and the Atlantic coast where farms are planned. Considering a farm size of 50 turbines, a considerable number of them is expected to be buckled down over a 20 years period by passing hurricanes: 16 out of 50 in Galveston County (TX) and 8 out of 50 in Dare County (NC), while numbers decrease in NJ and MA, where usually hurricanes loose strength.

Stronger hurricanes, category 4 and 5, cause more damage although occur less frequently. Overall, the damage occurrence over a turbine lifespan is dominated by one or two hurricanes. Most of the offshore wind potential is concentrated offshore Texas, Louisiana and North Carolina. The same for hurricane occurrence, at least one every 4 years, thus making the risk of significant loss of the capital investment relevant over a 20 years long period.

Yawing wind turbines, i.e. those that can oscillate and move accommodating fast wind direction changes, have better chances of survival. This would come to the expense of providing them a power back up, worth $ 30.000-40.000 each. The overall additional costs to improve hurricane resilience are estimated in 20-30% for onshore turbines, something less for offshore.

Another concern of a massive penetration of wind farms in hurricane prone areas would be how to assure the stability of the grid, thus of the power supply, through the shutdown period or the even longer time span required to restore severely damaged turbines. Again, as the recent case of Southern Australia showed [9], a base load of non intermittent and programmable is required. Thus here we are again talking about conventional thermoelectric power, you would think. Indeed “new energy” is often synonym of new unreliable installations with expensive back-up powered by fossil fuels, at best by natural gas. No thanks: our mind always run back to nuclear power!

Balance sheet of electricity generation capacity – 10 years of nuclear power at a glance

Since 40 years, IAEA develops and maintains a comprehensive database focused on nuclear power plants worldwide, namely PRIS (Power Reactor Information System). We have collected and analysed data starting from 2005 up to date. You can find here below shown in 5 graphs some information on new power reactors connected to the grid, those under construction, those being decommissioned on schedule, or those retired in advance.
We have not taken into account the Japanese reactors not in permanent shutdown. Since Fukushima accident and the following ban on NPP operations, 4 Japanese NPP have restarted. All of these between last summer and a few days ago. We have considered the remaining ones – not yet restarted neither yet in permanent shutdown – in a sort of Limbo: in fact, they are operable, but still waiting for the authorities and politicians’ starting signal.

As can be seen in Figure 1, the new installed nuclear power from January 2005 to January 2016 amounts to 37,9 GWe, a value which exceeds the reduced capacity from permanent shutdowns by 8,1 GWe.
Let’s consider the state-by-state contribution to the new installed reactors (Figure 2). China remarkably drives overall NPP replacement with roughly 18 GWe of new capacity connected to the grid, and with an average construction duration just above 5 years. In the same time frame, South Korea follows it by return, with an average schedule duration just below 6 years.

Fig.2 New capacity connected to the grid in the period 2005-2016
Fig.2 New capacity connected to the grid in the period 2005-2016

By analyzing the year-by-year progress (Figure 3), two notable aspects deserve our attention. First of all, we observe a significant drop of installed nuclear capacity in 2011, mainly as a direct or indirect consequence of the Japanese 11th March earthquake and tsunami: among the thirteen permanent shutdowns in that year, four are from the site of Fukushima Daiichi, while eight are from German power plants which have been forced to early retire due to the political decision to accelerate the country’s nuclear phase-out.
The second interesting aspect is the outstanding amount of new capacity connected to the grid in 2015, which doubled the results of the previous year.

What could we expect for the near future? Is the 2015’s achievement just a flash in the pan, or can we say that it is the restart of the nuclear renaissance?
To answer the question we ought to look at the amount construction starts in the last ten years. As can be seen in Figure 4, in four years from 2007 to 2010 the construction of nuclear power plants has experienced tremendous growth. After that, in some ways all construction plans have suffered from the impact of the Fukushima accident. However, there is a bunch of eleven Chinese reactors still under construction, starting from 2009-2010. So, taking into account the average duration of NPP construction in China – very short time, as per performances consolidated over the past ten years – as well as the number of reactors which are about to be completed in India, Japan, Pakistan, Russia, South Korea, UAE and USA, for the next two years we expect results equal to those for the last, or even more.
Figure 5 shows the state-by-state summary of the total capacity for all nuclear reactors under construction, as of January 2016.

In short, the race to nuclear power plants is currently destined to take place primarily on the racetracks of the Far East (from 2016 to 2020, six to eight nuclear reactors will probably be approved each year in China). And this despite the current slowdown in economic growth – also felt over there. The situation is made even more interesting by the fact that the countries chasing China are almost exclusively the emerging ones – some of these are “in the early days of development”.

Nothing new on the western front? Actually something is moving. Even if we are forced to admit that all factors against are dominant, at the moment. And perhaps it is time to fully review the role of nuclear power production in modernized countries, paving definitely the way for advanced nuclear systems – not necessarily always large. But that’s another story, about which we will not dwell here. That’s all folks, for now.
