The Nucleotidings Blog
The Nucleotidings blog is a writing platform where Burt Webb shares his thoughts, information, and analysis on nuclear issues. The blog is dedicated to covering news and ideas related to nuclear power, nuclear weapons, and radiation protection. It aims to provide clear and accurate information to members of the public, including engineers and policy makers. Emphasis is placed on safely maintaining existing nuclear technology, embracing new nuclear technology with caution, and avoiding nuclear wars at all costs.

Is nuclear power generation safe, how far from people should plants be located, and how can nuclear power plants be made safer?
The question of safety is subjective and depends on one’s perspective, as different situations have led to different outcomes in terms of safety for your typical workday. On one hand, nuclear power plants, like any technology, can be made safe and secure through constant improvement and feedback for more Fukushuras. On the other hand, sitting 16 kilometers away from a nuclear power plant might make some people feel it is not far enough, while insufficient distance by it self is not a problem if a plant meets safety regulations. Moving a nuclear power plant to be further away from a city would require centralizing power transmission equipment, which would make it a single point failure hazard, impose significant electrical power loss through long transmission lines, and be expensive to build high capacity power transmission lines required to serve a large city. Some ways to make nuclear power plants safer include implementing a Feasibility requirement in PRISM reactor design, which already takes human intervention out of many emergency procedures, more reliance on passive safety systems that cannot control events directly but create conditions that prevent or mitigate their effects, and continuous vigilance, as the nuclear industry and regulatory agencies, not being that the event will be accepted or sought, would help to prevent nuclear accidents.
What do you mean by “Fukushuras”?
“Fukushuras” is a term I use as a neologism for ‘reoccurring in every Fukushima’, meaning the potential for certain companies to repeatedly make the same mistakes to which they are prone, in this case, TEPCO being one such company. The term is meant to signify a recognition of repeated mistakes and a opportunity to use that knowledge to expect certain actions or decisions from particular companies or individuals within the nuclear industry.

In my last post, I discussed the Chinese National Nuclear Corporation and its great power in the Chinese nuclear industry. In 1994, the China Guangdong Nuclear Power Group (CGNPG) comprised of twenty subsidiary companies was capitalized by the Chinese government with nuclear power as its core business. It currently owns and operates two reactors in southern China with six more under construction and four being planned. It is also working on solar, wind and hydro power projects.
The first reactors of the CGNPG were of French design, built by Framatone. Working with the French technology, the CGNPG then developed the CPR-1000 pressurized water reactor which is intended to be the design for many of the new reactors being planned in China. In 2007, CGNPG contracted with the French company Areva for a new European Pressurized Reactor and with Westinghouse for a new AP1000 pressurized water reactor at Taishan. These new reactors are considered to be advanced Generation III reactors.
The Taishan reactor is being built in the heavily populated Pearl River Delta near Hong Kong. It will be the biggest nuclear reactor in the world with three times the radioactive materials of the Fukushima Unit One reactor that melted down in 2011. I have already mentioned that activists in Hong Kong are very concerned with the potential damage that an accident at the Taishan plant could cause. To this date, the Chinese government has not published detailed information on the design of the reactor and safety measure that will be implemented. The reactor will start operating in December of this year.
Greenpeace has reported that there have been a number of reports of problems with the construction of the reactor and that the radiation level around the reactor is already higher than the levels at a nearby operating reactor. The government has cancelled plans for another reactor in the Delta due to massive public protests.
In 2009, CGNPG set up a fund to raise over a billion dollars US for new energy projects. This was the first such fund set up by a state owned enterprise with the approval of the Chinese State Council. The Bank of China, the China Development Bank and other financial institutions will contribute to the fund and be part owners of the resulting projects. In 2013, the company changed its name to the China Nuclear Power Group signifying its intention to operate beyond the Guangdong province.
Here we are again. A huge corporation is building reactors in southern China and to keeping the public informed. Many defects are found in the construction indicating a lax attitude toward safety. An angry public has forced the government to cancel plans for reactor suggesting that social unrest is going to be a problem for future nuclear plans. This pattern is all too familiar. Once again, I have to say that I am afraid that China will not be able to construct and safely operate all the reactors that they have planned.

There was recently a nuclear industry conference in London sponsored by the World Nuclear Association (WNA). In their own words, the WNA is made up of “members who are responsible for virtually all of world uranium mining, conversion, enrichment and fuel fabrication; all reactor vendors; major nuclear engineering, construction, and waste management companies; and nearly 90% of world nuclear generation. Other WNA members provide international services in nuclear transport, law, insurance, brokerage, industry analysis and finance.”
Of course, any industry conference will promote the industry attending the conference and the London WNA conference was no exception. Nuclear power was touted as being critical to fighting global climate change. Exxon called for doubling the number of nuclear power reactors in the world by 2040. This would require that about four hundred new reactors be built and brought online in the next twenty six years. This would, of course, insure the viability and profitability of the nuclear reactor industry for decades.
Exxon Mobile presented their report Outlook for Energy that “bases its findings on data from 100 countries across the globe, looking at 15 demand centers and 20 fuel types. It also takes into consideration the technology and policy issues underpinning the world’s energy situation.” They concluded that nuclear was the cheapest low CO2 energy source and that alternatives like wind and solar had “significant grid knock-on costs.” If you will forgive my cynicism, I doubt that their analysis was unbiased. I will be posting future articles on the Exxon report.
The head of the European Union’s Nuclear Energy Agency called for greater transparency in pricing of energy sources. He was claiming that the only reason that sustainable alternatives had shown such explosive growth in the past few years was because of large subsidies. I have to admit that I am in favor of more transparency myself. I think that it is safe to say that had all the externalized costs in the fossil fuel industry been folded back into the cost of energy, sustainable alternative sources would be much cheaper. Fossil fuels have enjoyed massive subsidies and most of their astronomical profits would vanish if their subsidies were pulled by the U.S. Government. As for nuclear power, it would not exist if not for the nuclear weapons race during the Cold War. As far as transparency goes, if all the externalized costs of nuclear power that are not included in estimating the cost of nuclear power were included, it may be that it never was an economical source of power.
With respect to CO2 calculations, a little transparency would be helpful too. It has been estimated that it can take up to fifteen years for a nuclear reactor to offset the CO2 generated by mining, refining, construction, transportation, and waste disposal associated with nuclear power.
I would be overjoyed if there was an honest global discussion of the real costs associated with each of the sources of energy that are currently in wide use. I am confident that sustainable alternatives such as solar, wind, hydro, and geothermal would win over fossil and nuclear by a wide margin.
