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.

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.
Brazil is one of only two countries in South American that has nuclear power generating electricity. The other country is Argentina. During the 1970s and 1980s when they were governed by a military junta, Brazil had a secret nuclear weapons program. The rule of the junta ended in 1985 and in 1990, Brazil officially ended their nuclear weapons program.
The Angra Nuclear Power Plant is the only nuclear power plant in Brazil. It is located in the municipality of Angra dos Reis which is on the coastline of Rio de Janerio State. Two reactors were built there to provide power for Brazil.
The first reactor, called Angra 1, was purchased from Westinghouse. Construction was started in 1976 but there were delays in construction and it was did not connected to the Brazilian grid until 1982. Angra 2 was connected to the grid in 2000. It was constructed with help from West Germany. Construction of a third reactor, Angra 3, was begun in 1984 but halted in 1986. Construction was started again in 2010 and stopped again in 2014. The Brazilian government has decided auctioned off the components of the reactor to private investors who they hope will complete the reactor by 2023. The Eletronuclear company owns and operates the Angra Nuclear Power Station. Currently the two operating reactors provide about three percent of the electricity for Brazil.
Many of the workers in the Angra power plant live in compounds near the plant where security is handled by Eletronuclear. Last December, thieves blew up an ATM at the Mambucaba Condominium which is one of the workers compounds located about nine miles from the plant. Violent crime is increasing in Angra dos Reis and looting ATMs is a common activity for criminal.
Last week, ten armed men took security guards hostage at the Praia Brava Condominum where the plant workers live. They robbed the guests at a private party and fled in a speed boat. The Praia Brava is located less than a mile from the Angra power plant.
I have blogged before about the dangers posed by terrorists and soldiers to nuclear power plants. The taking of hostages and the use of modern weapons less than a mile from a nuclear power plant in Brazil raises the additional concern of threats to nuclear power plants by criminals.
Radioactive materials are worth a lot of money on the black market and thieves might be attempted to steal fuel rods from the nuclear power to sell to terrorists. The terrorists don’t have to have the sophistication to build nuclear bombs, just detonating a conventional explosive with radioactive materials packed around it would cause devastation and havoc in a major city. Another possible criminal move could be to break into a nuclear power plant, take the staff hostage and threaten to cause a meltdown unless a huge ransom is paid.
I have said for a long time that security at most nuclear power plants is not really sufficient to stop a well-armed and highly motivated team.

The bottom line is that the Trump administration wants to spend a lot of money to build more nuclear weapons. Considering that we and the Russians already have enough nuclear warheads to end human civilization many times over, their request for more of these weapons would appear to be primarily motivated by political and economic considerations. Political because they believe that having more weapons will make the U.S. appear more powerful. Economic because defense contractors will make billions of dollars building the new weapons. One thing their request for more nuclear weapons is not is good military policy.
Another change from the previous NPR is the fact that the new draft of the NPR makes scant reference to the critical role that diplomacy should play in nuclear strategy. No one can “win” a nuclear war. The best nuclear strategy is to prevent a nuclear war. Unfortunately, the nation’s diplomatic corps have been decimated by the Trump administration with many critical diplomatic posts going unfilled for more than a year.
The new draft NPR also makes no mention of Article VI of the U.N. Treaty on the Non-Proliferation of Nuclear Weapons although it does make vague references to reduction on nuclear weapons in the U.S. from Cold War levels. The U.S. has signed this treaty which obligates it to work on nuclear disarmament. If the U.S. proceeds with a major investment in the creation of new nuclear weapons, other signatories of the treaty may decide that the U.S. is not really serious about disarmament. This could reduce their commitment to disarmament.
The U.S., while not a signatory of Comprehensive Nuclear Test Ban Treaty, did voice strong support for the work of the Treaty organization in the last NPR. The new NPR states that the U.S. will not resume nuclear testing unless it is deemed necessary, what ever that means.
The draft NPR does affirm the U.S. support for NATO. However, Trump has repeatedly criticized NATO in his speeches and tweets. He has said that other NATO nations are not paying their fair share for the security that NATO provides.
There has been great concern that Trump is erratic and juvenile. People are afraid that he might capriciously order a nuclear strike against a perceived adversary. After all, the U.S. president has the sole authority to order the use of nuclear weapons. The draft NPR tries to reassure readers that “Any U.S. decision to employ nuclear weapons would follow a deliberative process.” The truth of the matter is that the Joint Chiefs would have about five minutes to try to talk the President out of using nuclear weapons. If he cannot be dissuaded from such action, then the entire U.S. military is bound by the Constitution to obey him.
In any case, the new draft NPR primarily reflects the policies of Secretary of Defense Jim Mattis, Secretary of State Rex Tillerson and Joint Chiefs Chairman Gen. Joseph Dunford. It cannot be said to be the policy of Trump except in such broad strokes as “spend more money on more nukes.” Hopefully, cooler heads will prevail when it comes time for Congress to pass budgets for military hardware.
