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.

  • Nuclear Reactors 1227 – Rolls-Royce Is In The Race To Develop and Deploy Small Modular Reactors

    Nuclear Reactors 1227 – Rolls-Royce Is In The Race To Develop and Deploy Small Modular Reactors

         Some investors are betting on Rolls-Royce (RR) stock rising because RR is entering the small modular reactors (SMR) market. SMRs will be manufactured in a factory and assembled at the site where they will operate. One of the selling points for SMRs is the expectation that they will be cheaper and quicker to construct than conventional nuclear power plants. Large-scale nuclear projects are notorious for running over budget and behind schedule.
         SMR technology has already been proven in Russia. In 2020, a floating power station was commissioned. The result was the Akademik Lomonosov barge which now provides power for two hundred thousand homes in the Russian city of Vilyuchinsk. Nuclear reactors usually used in nuclear icebreakers were used to construct the floating power plant.
         RR is designing SMRs with a four hundred and seventy megawatt capacity. Each one will be able to provide electricity to one million households.
         There are currently thirty-two countries that make use of nuclear power. However, SMRs will open up new markets in countries that have not used nuclear technology because of their relative simplicity and sixty year projected life spans. Many are expected to be located on existing sites of redundant coal or gas-fired power plants. The market for SMRs is projected to be worth more than thirty billion dollars a year by 2040.
         The U.K., U.S. and Canada are leading players in the development of these small nuclear reactors. The U.K. government is so interested that it has given RR two hundred and sixty million dollars. Four sites have been chosen where it is hoped that fifteen gigawatts of capacity will be installed. RR has signed memoranda of understanding with the Czech Republic, Estonia and Turkey for SMR projects.
          Not everyone is enthusiastic about more nuclear power. Greenpeace does not support nuclear power due to the long-lasting problems of dealing with spent nuclear fuel waste. High profile nuclear disasters at Chernobyl and Fukushima are reminders of how badly things can go wrong when nuclear technology fails.
         Last month, Germany shut down its last operational nuclear power plant. The German government has decided to invest in renewable energy instead. However, at the same time, Finland opened Europe’s biggest nuclear power plant. It is expected that about forty percent of the electricity in Finland will soon be produced by nuclear power.
         The most recent survey by YouGov suggested that nuclear power is becoming more popular. In September of last year, forty-eight of the those polled said that they supported the use of nuclear power in the U.K. In August of 2019, a similar poll found that only forty percent of the respondents supported nuclear power.
         From an investment point of view in the U.S., SMRs are receiving the backing of two American billionaires. TerraPower is being funded by Bill Gates. In collaboration with GE Hitachi Nuclear Energy, TerraPower has created the Natrium reactor. These are intended to provide constant power. They will compensate for when weather conditions for wind and solar farms are unfavorable.    Warren Buffet, through Berkshire Hathaway, owns PacifiCorp which is partnering with TerraPower in a feasibility study for a site in Wyoming.
          RR is not expected to have its first operation SMR until 2030.

  • Nuclear Weapons 819 – U.S. Is Working On Bunker Buster Bombs To Destroy Iranian Nuclear Facilities Buried Deep Under Mountains – Part 4 of 4 Parts

    Nuclear Weapons 819 – U.S. Is Working On Bunker Buster Bombs To Destroy Iranian Nuclear Facilities Buried Deep Under Mountains – Part 4 of 4 Parts

    Part 4 of 4 Parts, (Please read Parts 1, 2 and 3 first)
         Nuclear weapons advocates believe that the U.S. should retain dedicated nuclear bunker buster in order to destroy very deep targets. Former U.S. Air Force Chief of Staff General Norton Schwartz spoke on this topic at an event in 2014 at the Stimson Center think tank in Washington, D.C. He said that the guidance package on the B61-12 nuclear gravity bomb would make it easier to target hardened structures very deep underground. The B61-12’s dial-a-yield feature and tail kit could remove the need for dedicated earth-penetrating or large-yield nukes like the specially designed bunker-busting B61-11 and more powerful B83-1.
         Following the collapse of its nuclear deals with other world powers in 2018, Iran has been enhancing its underground nuclear facilities and rapidly advancing its nuclear program in recent years. Iran is now producing enriched uranium close to weapons grade levels. Inspectors recently discovered that Iran had produced uranium particles that were about eighty four percent pure U-235 at the Fordo fuel enrichment plant. This is far above the sixty percent figure claimed by Iran. It is very close to the ninety percent threshold for weapons-grade uranium.
         Corinne Kitsell and Götz Schmidt-Bremme are the British and German ambassadors to the IAEA nuclear watchdog respectively. They said, “The full range of findings outlined by the Director General’s report are alarming: Iran continues its unprecedented and grave nuclear escalation.”
         According to the head of the IAEA, Iran has sufficient enriched uranium to construct “several” nuclear bombs as of February of this year. All in all, the latest satellite images of Iran’s underground tunnels in the Zagros mountains underscores the U.S. military’s requirement for MOPs, as well as efforts by its adversaries to mitigate the capabilities of those weapons.
         Since the Trump administration pulled the U.S. out of the Joint Comprehensive Plan of Action (JCPA) for the monitoring of Iran’s nuclear program, there have been ongoing efforts to either restore the JCPA or create a new program to prevent Iran from creating its own nuclear arsenal. Negotiations with Iran over a new nuclear deal have had their ups and downs since the U.S. pulled out of the deal. Currently, the European powers in the original JCPA, have encouraged and even pressured the U.S. to come to terms with Iran. In the meantime, Iran has been resisting and violating some of the IAEA monitoring programs still in place.
         Given the missiles that could reach Israel and the continued belligerent statements against Israel from the Iranian government, Israel has repeatedly said that they would never allow Iran to obtain nuclear weapons. They have said that they will attack Iran if that appears to be imminent, regardless of whether the U.S. approves and joins the attack. Hopefully, some sort of deal can be reached with Iran to halt its progress towards nuclear weapons before there is a need for the bunker busters in the U.S. arsenal.
