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 Weapons 836 – Does Israel Have An Effective Nuclear Arsenal – Part 1 of 2 Parts

    Nuclear Weapons 836 – Does Israel Have An Effective Nuclear Arsenal – Part 1 of 2 Parts

    Part 1 of 2 Parts
         As the war between Israel and Hamas rages on in Gaza, international organizations have expressed their concern over a widening of the conflict because it has the potential to involve nuclear weapons.
         In October, the surprise Hamas attack on Israel started a war that has taken the lives of thousands of civilians. Israel continues to carry out what the head of the U.N. called “collective punishment” against Palestinians civilians. The attack on Israel also exposed a weakness in its military defense. Many question whether Israel could still defend itself with conventional weapons.
         In an October 9th post on X, Israeli lawmaker Revital Gotliv urged his government to unleash a “doomsday weapon” carried by Israel’s Jerico ballistic missiles. However, the extent of Israel’s nuclear capabilities and whether they would be effective in battle is an open question.
         Many international organizations and countries believe that Israel has nuclear weapons. However, Israel has conducted few, if any, tests of such weapons. The mystery that surrounds its nuclear program has raised questions among military experts about the nation’s actual deterrence capabilities. Israel has long maintained a policy of “nuclear ambiguity”. It has never directly confirmed or denied the existence of a nuclear arsenal.
         Daryl Kimball is executive director of the Arms Control Association (ACA). He said, “Israel is universally believed to possess nuclear arms stored in a partially disassembled state”. The nation is believed to have about ninety nuclear war heads as well as the ability to build a hundred more with its fissile materials stockpiles.
         Kimball stated that the use of nuclear weapons or even the threat of their use would make Israel “an international pariah and a target of foreign, conventional military attack”. The International Campaign to Abolish Nuclear Weapons (ICAN) issued a statement recently that “Israel is a nuclear-armed state, the only such state in the Middle East”.
         Alicia Sanders-Zakre is ICAN’s policy and research coordinator. She said, “Israel’s possession of nuclear weapons significantly increases the risks associated with the conflict and contributes to regional tensions. Escalation is a real danger”.
         The International Atomic Energy Agency (IAEA) said that it was “following with concern” developments in the Middle East where it performs activities aimed at preventing the spread of nuclear weapons.
         The Treaty on the Non-Proliferation of Nuclear Weapons (TNPNW) considers the U.S., Britain, China, France and Russia to be “nuclear states”. They have this designation because they built and tested nuclear explosives before 1967. North Korea, Israel, Pakistan and India have nuclear weapons but have never signed the treaty.
         The China Aerospace Science and Industry Corporation Limited is an aerospace defense contractor for the People’s Liberation Army. They recently published a paper in their journal. The paper said that the five treaty-recognized nuclear powers “all have land, sea and air-based nuclear strike capabilities and maintain a high level of nuclear combat readiness”. However, it is believed that Israel only has land-based capabilities. The effectiveness of nuclear strikes based solely on land-based capabilities is “questionable”.
         The nuclear nations that have not signed on to the non-proliferation treaty have conducted less than ten nuclear tests each. The U.S. has conducted more than a thousand nuclear tests. North Korea is the only nation that has conducted any nuclear tests since the end of the 1990s. Although other countries are no longer testing their nuclear weapons, they have been able to maintain their nuclear arsenals through scientific assessments such as computer simulations of nuclear processes.

  • Nuclear Reactors 1294 – Ontario Power Generation Is Working On Construction Of Four Small Modular Reactors At Its Darlington Site

    Nuclear Reactors 1294 – Ontario Power Generation Is Working On Construction Of Four Small Modular Reactors At Its Darlington Site

         Ontario Power Generation (OPG) will construct and operate four small modular reactors (SMRs) at its Darlington site. It is estimated that these SMRs will contribute about eleven billion dollars to Canada’s GDP. This will include about one billion dollars to Ontario’s GDP. The SMRs will create and sustain two thousand jobs every year in Canada over the next sixty-five years. This information was reported by the Conference Board of Canada (CBC).
         The SMR report said, “There is now an increasing need for investing in stable and reliable energy resources, such as commercial-scale SMR technology. The deployment of more nuclear power in Ontario is a major investment decision. It is therefore important to understand the potential economic benefits for the province and the country of investing in new nuclear power generation.”
         The CBC collaborated with OPG to analyze the economic impact and fiscal benefits of building and operating four SMRs at the Darlington site. It found that the SMRs would have a significant positive impact on the Ontario and Canadian economies. Ontario would reap eighty nine percent of the economic benefit associated with the project.
         Each SMR constructed would increase GDP by almost two billion seven hundred million dollars and provide five hundred jobs annually over the sixty-five year period. In addition, the amount of tax revenues accruing to all levels of government is expected to be about three billion five hundred million dollars over the next sixty-five years. This includes plant construction and operations. The estimated number of jobs created by the project will be about one hundred and thirteen thousand jobs provincially and one hundred and twenty-eight thousand jobs nationally.
         The CBC found that “The economic impact, or the ratio of increased GDP to spending (the ‘economic multiplier’) is 0.82 – each dollar spent would increase Canadian GDP by CAD0.82 across the total lifespan of the technologies.”
         On October last year, OPG submitted an application to the Canadian Nuclear Safety Commission (CNSC) for a license to construct a GE Hitachi Nuclear Energy (GEH) BWRX-300 at the Darlington site. This license is required before any nuclear construction work on the SMR can start. Site preparation has already begun at the site. OPG intends to make a construction decision by the end of 2024. Construction of the reactor is scheduled to be finished by late 2028. The supply of power to the Ontario grid should start in 2029.
         The Ontario government announced last July that it is working with OPG to start planning and licensing for three additional BWRX-300 reactors at Darlington. Subject to Ontario government and CNSC regulatory approvals on construction. The additional SMRs could come online between 2034 and 2036. This scheduling would permit OPG to apply earnings from the construction of the first SMR to deliver cost savings on subsequent SMRs. Constructing multiple units will also permit common infrastructure such as cooling water intake, transmission connection and control room to be used by all four units instead of just one, which would further reduce cost.
         Ken Hartwick is the OPG President and CEO. He said, “Being the first North American mover of this innovative technology positions Ontario as a world leader in nuclear and a welcoming destination for new business. Our plan to construct four new reactors at Darlington will also generate opportunities across Ontario and Canada as suppliers of nuclear components and services have an opportunity to expand to serve the growing SMR market here and abroad.”
