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 1105 – Silicon Valley Venture Capital Flows To Nuclear Power – Part 3 of 4 Parts

    Part 3 of 4 Parts (Please read Parts 1 and 2 first)
         In recent years, private investors and venture capitalists have been putting their money into nuclear startups. They seem to driven by a newfound sense of urgency to respond to climate changes. Although nuclear power plants do not release greenhouse gases as they operate, a lot of carbon dioxide is release when they are constructed and when their fuel is processed and transported. Venture capitalists are also attracted by the opportunity to fund underdog companies with a huge upside.
         The venture capital model is based on big bets. Venture capitalists spread their money across many companies. Most of these startups are expected to fail or, at most, break even. However, if one or two companies grow to an enormous size, the funders will more than cover the costs of all losses. This is the investing model that supported the rise of Silicon Valley giants such as Apple, Google and Tesla.
         Some venture capitalists are especially excited about the possibility of nuclear fusion as a power source. It is, after all, the process that fuels all the stars in the sky. It also, for the most part, generates no long-lasting radioactive waste. However, some of the proposed types of fuel such as deuterium and tritium can produce neutrons which will brittle metal components and make them mildly radioactive over time. It has been extremely difficult to create a lasting fusion reaction on Earth. The generation of net energy from a fusion reaction has just been accomplished after seventy years of research. There is still a long way to go to develop a fusion reactor which can produce enough steady energy for commercial applications.
         Vinod Khosla is a venture capitalist. He said that, “It’s far better than nuclear fission. It’s far better than coal and fossil fuels for sure. But it’s not ready. And we need to get it ready and build it.”
          Khosla is not the only venture capitalist interested in nuclear fusion. The private fusion industry has received almost five billion dollars of funding, according to the Fusion Industry Association (FIA). More than half of that has been since the second quarter of 2021 said Andrew Holland, CEO of the FIA.
         Others are excited about new advances in nuclear fission. Fission is the more traditional type of nuclear power that is based on breaking atomic nuclei apart.
          Zachary Bogue is the DCVC founder. He has invested in the micro-nuclear reactor company Oklo. He said, “Advanced nuclear fission is a quintessential deep-tech venture capital problem. There is technical and regulatory risk, but if those problems are solved, there are just massive-scale returns … all of those elements are a perfect recipe for venture capital.”
         While these bets seem expensive and risky compared with venture capitals recent focus on software and consumer technology, they will still bring a faster and more agile approach than the old-line nuclear industry. Most of the nuclear fission power reactors operating these days are approaching the end of their originally licensed life spans.

  • Nuclear Reactors 1104 – Silicon Valley Venture Capital Flows To Nuclear Power – Part 2 of 4 Parts

    Part 2 of 4 Parts (Please read Part 1 first)
         Some of the rapid pace of increase in investment in the nuclear sector is explained by its starting point which was virtually zero.
         David Schlissel is a director of resource planning analysis at the Institute for Energy Economics and Financial Analysis, a market research firm. He said, “This is still pretty small compared to the private investments in renewables,” like wind and solar, for example.”
         The venture market slowed overall in 2022. Nuclear power investment is no exception. Concerns over the war in Ukraine, inflation, a wave of layoffs and hints of a coming recession have made investors nervous in the public and private markets.
         Brett Rampal is a nuclear energy expert who evaluates investment opportunities and consults for nuclear startups. He said, “At the beginning of the year, we were looking at a much different financial paradigm for nuclear startups seeking funding. Now, following a war, and inflationary related forces, the fundraising market is just not what it was earlier and that is challenging for everyone seeking funding and support, nuclear or otherwise.”
         More than three hundred billion dollars flowed into the venture capital industry in 2021. Rothrock estimates that there will be about one hundred and sixty billion dollars in 2022. According to Rothrock, “I’m sure that some funds that pull back may never come back. But most investors who are putting money into a nuclear company understands that it will not be a quick investment. Entrepreneurs and investors at the level we are talking for nuclear are playing the long game, they have to. These projects will take time to mature and to generate real cash flows.”
         The Inflation Reduction Act which was signed by Joe Biden in August included three hundred and sixty-nine billion dollars in funding to help combat climate change. This legislation has given nuclear power investors a very significant positive signal. Rampal said, “The IRA investment and production tax credits are not nuclear specific credits, they’re clean energy credits that nuclear is now considered a part of, and that sends a real important message to people and investors that would consider this space.” According to Rampal, the vote by the European Union in July to keep some specific uses of nuclear energy and natural gas in its taxonomy of sustainable sources of energy in some circumstances also encourages investors.
         The nuclear power industry in the U.S. was launched as a government project after the U.S. constructed the first atomic bombs during World War II. In 1951, a nuclear reactor produced electricity for the first time in Idaho at the National Reactor Testing Station which would eventually become the Idaho National Laboratory.
         In the 1960s and 1970s, large conglomerates constructed huge nuclear power plants. Almost all of those projects ran over budget. According to a 2011 report from the Congressional Budget Office, “As a consequence, most of the utilities that undertook nuclear projects suffered ratings downgrades—sometimes several downgrades—during the construction phase.”
        Generation of electricity in the U.S. peaked around 2012 with one hundred and four operating reactors. This information was provided by the U.S. Energy Information Administration.

  • Nuclear Reactors 1103 – Silicon Valley Venture Capital Flows To Nuclear Power – Part 1 of 4 Parts

    Part 1 of 4 Parts
         Venture capitalists in Silicon Valley and other tech hubs are investing significant money in nuclear energy for the first time. That is changing the pace of innovation in the nuclear industry. Ray Rothrock is a longtime venture capitalist who has personal investments in 10 nuclear startups. He said, “There has not been a resurgence of nuclear power, ever, since its heyday in the late 1970s. Now that is changing. I have never seen this kind of investment before. Ever.”
          Jacob DeWitte is the CEO of the micro-reactor startup Oklo. He says that the landscape has changed dramatically since he began raising funds in 2014. At the time, he was a part of the Y Combinator startup incubator. He added, “More investors are interested, more investors are excited by the space, and they’re getting smarter to do the diligence and know what to do here — which is good.”
         John Parsons is an economist and lecturer at MIT. He said, “I think having fresh perspectives is really good.  Nuclear energy is a very complex science, and it’s been supported by the federal government and at these national labs. And so that’s a very small circle of people. And when you broaden that circle, you get a lot of new minds, different thinking, a variety of experiments.”
         Parsons continued, “In any industry, there can be a ‘groupthink’ or ‘narrowness’ in the way things are done over time. With private investment in the space, there will be out-of-the-box thinking. Maybe that out-of-the-box thinking doesn’t produce anything useful. Maybe it turns out that the old designs are the best. But I think it’s really wonderful to have the variety of takes.”
         In spite of the enthusiasm of the previous quotes, not everyone is so optimistic that the recent flow of venture dollars will actually lead to significant progress.
           Naomi Oreskes is a professor of the history of science at Harvard University. She said, “Investors have often invested in stupid things that didn’t work. Because the reality is that in a 75-year history of this technology, it has never been profitable in a market-based system. If investors are putting money into nuclear now, that’s because they think they can make money, and I can only think they believe they will make money because they think that there’s a big opportunity to have the federal government pick up a big part of the tab.”
         From 2015 to 2021, total venture capital deal flow in the U.S. has increases fifty-four percent in terms of deals actually closed and two hundred and ninety four percent by dollar value. This is according to data compiled by the private capital market research firm Pitchbook. In that same time period, climate investing deal flow in the U.S. rose by two hundred and fourteen percent in terms of volume and one thousand three hundred and forty-eight by dollar value. In the nuclear space, investments rose even faster by three hundred twenty five percent by volume and three thousand six hundred forty-two percent by dollar value.
