Example Q&A with the Artificial Burt Webb
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.

A third reason that China does not want to talk about NPPs in the BRI context is the fact that China intends to build NPPs in countries with lax regulatory environments. This constitutes a major risk to the security of the global community of nations. For example, Sudan is an important part of the BRI. When the Institute for Science and International Security ranked two hundred nations with respect to their ability to limit the illicit trafficking in nuclear materials, Sudan was near the bottom of the list. Sudan has not signed the IAEA Additional Protocol which improves the ability of the IAEA to verify that nuclear fuel is only used for civil energy purposes.
China is locked in a battle with Russia to corner the market on nuclear technology exports. The export of NPPs to developing nations is part of their strategic plan whether or not it makes sense for the nations accepting the Chinese deals. Nuclear energy costs too much money, too much time and is too risky to be a good choice for these countries. And, renewable energy is rapidly dropping below the cost of fossil fuels and nuclear power. They do not need Chinese nuclear power reactors.
Nuclear power supporters like to point out that the comparable levelized cost of nuclear power is about the same as it is for solar photovoltaics. The problem is that this is based on estimates of the cost of the power source over its lifetime. The cost of solar is dropping but the cost of nuclear is not. Instead of getting cheaper when a country expands it nuclear sophistication and infrastructure, the cost of constructing and operating nuclear reactors usually rises. In addition, the cost of nuclear plant construction almost always rises sharply during construction and the schedule for completion almost always slips seriously. On the other hand, the cost of additional wind and solar installations falls with experience.
China boasts of being at the forefront of the development of advanced nuclear reactor designs. They like to point to their internally designed Hualong-One reactor as an example of their inventiveness that is competitive with other reactor designs. They are planning to build copies of this reactor design in at least five countries at widely separated locations. There are no Hualong-One reactors currently in operation anywhere. Based on the evidence to date, innovation and experience in nuclear technololgy may not lead to cost reduction.
In addition to the new Hualong-One design, the European Union is working on the new European Pressurized Reactor (EPR) and Westinghouse in the U.S. is touting the new AP1000 reactor design. In December of 2017, the first EPR reactor ever build was coming on line in China. During a test, a boiler cracked and the schedule for completion slipped. This was the third delay in two years and it cost the project seven hundred and seventy million dollars. Meanwhile, an AP1000 reactor also being built in China had to be delayed a month after the EPR problem. Delays are common on NPPs. Currently, fifty-five nuclear power plants are under construction. So far, two thirds of these projects are behind schedule, so delays are more common than not.
The is also the threat of terrorism to worry about. In the three years between 2013 and 2016, the Center for Nonproliferation Studies reports that there were almost seven hundred incidents where radioactive materials were stolen or lost in forty-six countries. In that time, there have been nine thefts of highly radioactive materials in Mexico alone.

On a number of occasions, I have blogged about my fears that developing nations could be walking into a trap if they accepted offers of nuclear technology exporting nations such as Russia and China to build, fuel, operate, and dispose of spent fuel from nuclear power plants in those developing nations. The deals can look very attractive with the exporters offering big loans on generous terms and a complete package of services.
China announced the Belt and Road Initiative (BRI) in 2013. They are dedicating over a trillion dollars to projects in a swath of nations from China to Europe for the stated purpose of trade creation, economic development and renewable energy. However, concerns have grown over the possible military strategic benefits of the BRI which China has tried to soft-pedal.
The Chinese government has created several websites associated with the BRI. It is interesting and a little odd that none of those websites make any mention of nuclear power plant (NPP) projects although China has plans to build over thirty nuclear power plants as part of the BRI. Many of the countries where the Chinese intend to build NPPs are not members of any non-proliferation treaties and they do not have regulatory frameworks for safeguarding nuclear plants and materials.
Developing nations who are the target of the Chinese nuclear export business should be under no illusion that China is offering them these deals out of kindness. China has economic and geostrategic goals of its own that will be furthered by spreading around Chinese nuclear power reactors in developing nations whether or not they benefit the customers.
The vision statement for the BRI says that one of the goals is to advance nuclear power cooperation and the Belt and Road Energy Cooperation website does mention some bilateral nuclear agreements. Many of the countries that are considered as prospects for Chinese nuclear exports are part of the BRI initiative. However, as mentioned above, three main websites for the BRI make no mention of NPPs.
One of the reasons that China might not want to mention and publicize the NPPs is because many nuclear technologies are dual-use. This means that the same technology that can produce enriched uranium for nuclear fuel can also enrich uranium for nuclear weapons. Keeping NPPs out of the publicity for the BRI reduces public concern about possible proliferation of nuclear weapons in the BRI countries.
A second reason for China to avoid publicizing BRI NPPs is the fact that China has been guilty of violating its obligations under the rules of the international Nuclear Suppliers Group (NSG) of which it is a member. It has provided nuclear materials to countries including Pakistan who are not members of the NSG and are not entitled to receive such materials under the rules of the NSG. Pakistan has not agreed to employ International Atomic Energy Agency safeguards or to slow down its nuclear weapons program. In spite of this, China is involved in six NPP projects in Pakistan.

A muon is a subatomic particle that is similar to an electron but has two hundred times as much mass. It has an electrical charge of minus one and a spin of one half. It is categorized as a “lepton” which means that it does not have any substructure composed of simpler particles. Muons are unstable and only have a half life of about two millionths of a second. However, this is longer than the half life of many subatomic particles. When a muon decays, it produces an electron and two neutrinos. Because it is not affected as much by magnetic fields as an electron, it can penetrate much further into solid objects. Muons produced by cosmic rays can penetrate deep into the Earth. About 10,000 muons are hitting every square yard of the earth’s surface every minute.
The National Nuclear Laboratory (NNL) is a UK government owned and operated nuclear services technology provider covering the whole of the nuclear fuel cycle. Almost ten years ago, researchers at the (NNL) and Glasgow University in Scotland discovered that muons interacted differently when they encountered uranium as opposed to other elements. Because of the greater density of the uranium, instead of passing right through, the muons are scattered. Lynkeos, a commercial company, was formed to take advantage of this behavior by turning it into a commercial product for the nuclear industry. It has the potential to aid decommissioning, detection and storage of radioactive materials. This could save the nuclear industry millions of dollars.
The muon detection technology, called the Muon Imaging System (MIS) is already in use at Sellafield. The owners of the Cumbrian reprocessing plant have invested over six million dollars in the research. Innovate UK also supplied about two million dollars. Additional funding was supplied by the Engineering and Physical Sciences Research Council, the Science and Technology Facilities Council and the Royal Society of Edinburgh. The UK firm hopes to export the MIS to other countries across the globe to help with the cleanup of nuclear sites.
The CEO of Lynkeos said “The Muon Imaging System can be used for a variety of purposes, whether that’s inspecting old/spent material used in nuclear production to see if it’s safe to store, for imaging the products of thermal treatment processes or inspecting historic waste without needing to chip away its concrete encasing.”
“This form of detection is providing the nuclear industry with an inexpensive method for testing waste materials, to which there is currently no other technological option. This should help to significantly lower costs within the nuclear industry.”
I have already blogged about the use of a muon detection system to search for the nuclear fuel in the reactor cores in the ruins of the reactors in Fukushima, Japan. The muon detectors did not show that the uranium fuel was still in its original position in the core of the reactor. This indicated that the fuel had melted down through the bottom of the containment vessel.
