Atomic Show #314 – Economies of scale for micro, small, medium, large reactors – with James Krellenstein

James Krellenstein is a physicist, consultant and nuclear energy historian. He is currently employed as a senior advisor to Global Health Strategies. He started up their decarbonization practice with an emphasis on nuclear energy along with renewables. He was the lead author on GEH’s report on ways to reduce global dependence on Russia for necessary…

IRA’s Clean Electricity Tax Credits (Sections 48E and 45Y) are an under-appreciated boon for new nuclear power

IRA’s Clean Electricity Tax Credits (Sections 48E and 45Y) are an under-appreciated boon for new nuclear power

The Inflation Reduction Act (IRA) should make an important contribution towards mitigating future inflationary periods. It accomplishes this beneficial goal by providing important support for facilities that increase US clean electricity production. The key sections of the Inflation Reduction Act are new IRS code sections 45Y and 48E. Respectively, these are called the Clean Electricity…

Ontario leads the way to clean energy credit registry

Ontario leads the way to clean energy credit registry

On September 26, 2022, Microsoft Canada and Ontario Power Generation (OPG) announced an important agreement for clean energy credits (CECs). The most significant part of the deal was the fact that OPG would supply the credits from its nuclear and hydro-electric plants. Microsoft will procure the credits on an hour by hour basis to match…

Why are smaller reactors attracting so much interest?

Small modular reactors (SMRs) are gaining increased attention as a major opportunity in clean power production. They are a welcome tool in the necessary transition from an energy system dominated by hydrocarbon combustion to one that produces more power for more people with dramatically reduced greenhouse gas emissions. As a partner in Nucleation Capital, a…

What makes smaller nuclear power systems so exciting?

Let me start by dispelling the notion that I think smaller, modular, manufactured nuclear power systems – often called SMRs or micro reactors – are the be all and end all solution to anything, including climate change or energy security. Though not THE solution, they have the potential to be a crucial, uniquely capable part…

Preliminary lessons available to be learned from Feb 2021 extended cold spell

A large number of “hot takes” are appearing now that the cold wave that began arriving on Feb 11, 2021 has moved into areas where sub-freezing temperatures in Feb are normal. If the politically charged nature of the takes could be harnessed, the energy released would be able to keep quite a few homes supplied…

Atomic Show #289 – All Reactors Large and Small

Pro-nuclear advocates generally agree that there is a large and growing need for new nuclear power plants to meet energy demands with less impact on the planet and its atmosphere. There is frequent, sometimes passionate discussion about the most appropriate reactor sizes, technologies and specific uses. Atomic Show #289 is a lively discussion among some…

Atomic Show #271 – Improving Nuclear Cost and Schedule Performance

One of the most persistent arguments against the rapid deployment of nuclear energy is that projects are too expensive and take too long to complete. Based on the performance of the few nuclear plants that have begun construction in the West during this century, it’s hard to disagree. But there is solid evidence from projects…

Turning nuclear into a fuel dominated business

Under our current energy paradigm, nuclear power has the reputation of needing enormous up-front capital investments. Once those investments have been made and the plants are complete, the payoff is that they have low recurring fuel costs. Just the opposite is said of simple cycle natural gas fired combustion turbines. They require a small capital…

Why can’t existing nuclear plants make money in today’s electricity markets?

What does it mean when nuclear plant owners tell people that their plants are struggling to make money in competitive markets as currently structured? They are attempting to more precisely state what is often misleadingly dismissed by journalists as “nuclear plants cannot compete.” The more commonly used statement gives the impression that nuclear plants produce…

With immediate and profound changes, U.S. nuclear power can become an unexpected but welcome low carbon wedge

Researchers from Carnegie Mellon, University of San Diego, and Harvard recently published a useful call to action titled U.S. nuclear power: The vanishing low-carbon wedge. For pro-nuclear observers and debaters, their conclusion may seem quite depressing. It should be a source of profound concern for all who care about climate change that, for entirely predictable…
