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 844 – Rising Hostilities In The Middle East Raise Concerns About Iranian Nuclear Program – Part 1 of 2 Parts

    Part 1 of 2 Parts   
         The Israeli-Hamas war has triggered a new Middle Eastern regional conflict involving the United States and the Houthis in Yemen, a militant group described as proxies for Iran.
         The Iranians have long been accused of funding and arming the Houthis in Yemen, Hamas in Gaza and Hezbollah in Lebanon. The situation has been further aggravated by Iran’s new conflict with its neighbor Pakistan, a longstanding Asian nuclear power.
         In a report on January 17th, Cable News Network (CNN) said Pakistan has strongly condemned an Iranian airstrike inside its borders that killed two children. Pakistan called it an “unprovoked violation of its airspace” and warned of retaliation.
         Iran claimed that it used “precision missile and drone strikes” to destroy two strongholds of the Sunni militant group Jaish al-Adl, known in Iran as Jaish al-Dhulm, in the Koh-e-Sabz area of Pakistan’s southwest Baluchistan province, according to Iran’s state-aligned Tasnim News Agency.
         The attack on Pakistan comes after Iran launched missiles in northern Iraq and Syria last week. It is the latest escalation of hostilities in the Middle East where Israel’s ongoing war in Gaza risks spiraling into a wider regional conflict, said CNN.
         In a statement issued on January 18th, UN Spokesperson Stephane Dujarric said Secretary-General António Guterres “is deeply concerned about the recent exchange of military strikes between Iran and Pakistan, which have reportedly caused casualties on both sides.”
         The new conflicts have renewed the longstanding speculation on Iran’s plans to go nuclear. This concern has also been triggered by a report released last November by the Vienna-based International Atomic Energy Agency (IAEA).
         A joint statement by the U.S., France, Germany and the U.K. last December warned that the November 2023 report by the IAEA indicated that Iran had increased its rate of production of uranium enriched up to sixty percent at Natanz and Fordow to levels observed between January and June 2023.
         The four countries declared that “These findings represent a backwards step by Iran and will result in Iran tripling its monthly production rate of uranium enriched up to 60%. We remain committed to a diplomatic solution and reaffirm our determination that Iran must never develop a nuclear weapon.”
    “We condemn this action, which adds to the unabated escalation of Iran’s nuclear program. The production of high-enriched uranium by Iran has no credible civilian justification, and the reported production at the Fordow Fuel Enrichment Plant and the Pilot Fuel Enrichment Plant further carries significant proliferation-related risks.”
    “We also take note of Iran’s decision to revert to the same cascade configuration as the one discovered by the IAEA in Fordow earlier this year. Iran’s delay in declaring this change in January 2023 cast serious doubts on Iran’s willingness to cooperate with the IAEA in full transparency”, the statement added.
    The New York Times published a front-page story on January 16th, in which it warned that “while Iran has ramped up the production of uranium drastically in recent weeks, renewing fears that it may be speeding again toward the capability of fabricating several nuclear weapons, it has carefully kept just below the threshold for bomb-grade fuel. That is considered the red line that could trigger military action against its underground nuclear complexes.”

    Nuclear Reactors 1338 – NextEra Energy Wants To Make Reductions In Its Emergency Plan For Nuclear Accidents – Part 2 of 2 Parts

    Part 2 of 2 Parts (Please read Part 1 first)
         In an email statement to New Hampshire Public Radio, Orlove attempted to assuage any concerns about the quality of the plant’s emergency plans. He said, “The proposed plan does not change the number of full-time employees at Seabrook Station and does not move emergency response roles out of state. All our on-site personnel would respond, as they would now, to an emergency at Seabrook Station. Understand that we already have a robust emergency response organization and processes at each nuclear facility. This change proposes a hybrid emergency response program that would allow experts at our other locations to provide support, if needed.”
         Orlove said that the company previously had to fill each emergency role from staff at each nuclear plant. He said that this “meant less flexibility. We need to have depth (“bench strength,” if you will) in all our emergency roles. Currently, some personnel are assigned to roles that the company has determined are not necessary. Eliminating those roles makes additional site personnel available for the roles that are needed.”
         A few positions will be designated “remote,” according to Orlove. That means that those jobs could be performed by the personnel within the area of the nuclear facility or by personnel from another nuclear facility.
         He said that NextEra was proposing extending response times for some positions during emergencies because training and simulations “demonstrates that on-site personnel are fully capable of managing one of our facilities in an emergency for extended periods of time,” and a longer response time would allow employees “greater flexibility” when they’re not working at the plant.
         In response to questions about how remote communications could fail during a weather emergency, he said that remote communications currently take place daily, and has always been part of the emergency plan, given that the current emergency response facility is 10 miles away from the plant.
    Orlove went on to say that “All our nuclear facilities, including Seabrook Station, already include remote response roles in emergencies and any increased incorporation of remote responses in the emergency plan does not in any way impair the site’s emergency response preparedness.”
         Federal lawmakers from New Hampshire and Massachusetts have sent letters to the NRC, asking them to ensure the changes don’t diminish public safety and encouraging them to help the public learn about the plans before deciding whether to approve them.
         On December 5th, the New Hampshire congressional delegation wrote “We recognize the need for coordinated planning and synchronization among facilities and appreciate efforts to focus on emergency preparedness. However, we have serious questions about the details in the proposed plan related to staffing locally in Seabrook, New Hampshire.”
         Lawmakers asked how the plan revisions would improve safety. They wanted to know whether NextEra would reduce the number of full-time employees that hold emergency response roles. They were also worried about how increasing remote response positions would impact safety. The legislators urged the commission to ensure the public has an opportunity to provide comments about the plans.
    Senators Ed Markey and Elizabeth Warren sent a letter on Dec. 21 urging the commission to reject changes that would decrease safety for people living near nuclear plants.
    “We strongly believe that the NRC’s pending decision must prioritize public safety over potential cost savings for the operator,” they wrote.
    The NRC said they had not set an expected date for their decision.

    Nuclear Reactors 1337 – NextEra Energy Wants To Make Reductions In Its Emergency Plan For Nuclear Accidents – Part 1 of 2 Parts

    Part 1 of 2 Parts
         NextEra Energy owns the Seabrook Nuclear plant and it is proposing changes to its emergency response plan. Advocates and lawmakers in New Hampshire and Massachusetts have raised concerns about whether it would reduce protections in the case of a nuclear emergency.
         NextEra has filed a proposal with the U.S. Nuclear Regulatory Commission (NRC) to standardize emergency plans for four nuclear power plants. These include the Seabrook in New Hampshire, Point Beach in Wisconsin, and St. Lucie and Turkey Point in Florida.
         The NextEra proposal includes 49 changes characterized as potential “reductions in effectiveness.” In the filing, they say they’ve provided “detailed justification” for those requested changes. They added that the plan “continues to provide an adequate response to radiological emergencies.”
         Changes described as potential reductions in effectiveness in the proposal include NextEra seeking to reduce the number of staff assigned to particular emergency functions. They want to increase response times for certain emergency response positions from 60 minutes to 90 minutes.
         Scott Burnell is a spokesperson for the NRC. He said that “reduction in effectiveness” refers to a proposed change that would be less effective than the company’s current plan. However, he noted that regulators would “reject any changes that would fail to effectively protect the public. The NRC requires nuclear power plants to have emergency preparedness procedures that will effectively protect the public if necessary. A plant’s existing procedures can exceed that standard, so a “reduction in effectiveness” in that case will continue to effectively protect the public. A “reduction in effectiveness” cannot result in an ineffective plan.”
         Bill Orlove is a spokesperson for NextEra. He said that a reduction in effectiveness “does not imply that the change is degrading emergency preparedness. In fact, most of the changes that are in that list are consistent with current NRC guidelines or industry standards, but we must still characterize them as reductions, compared to the last emergency plan that was approved by NRC.”
         Sarah Abramson leads the C-10 Research and Education Foundation (CREF). It is a group that advocates for safety for people who live near the Seabrook plant. She says her group is concerned about the changes. She specifically mentioned the potential reliance on people working remotely if an emergency were triggered by a storm.
         Abramson said, “Weather events have coinciding consequences. They cause widespread power outages. They can affect cellular communication. The more you place reliance on remote wireless communication as your sort of sole singular plan to communicate in an emergency, I think we’re walking down a dangerous road of having many single points of.”
         For Abrahamson, a “reduction in effectiveness,” whether bureaucratic terminology or not, is a cause for concern.
         She added that, “We want to see Chairman Hanson and the rest of the commission, when they’re looking at this type of proposal, or this one specifically, to reject anything that would reduce the effectiveness of an emergency plan. Even one reduction in effectiveness is unacceptable, let alone 49.”
