A look at refueling in the COVID-19 era

The government of the United States should throw its muscle behind ramping up a mammoth, rapid rollout of all forms of renewable energy through Operation Warp Speed, similar to what is being done with COVID-19, Clive Thompson writes in an Ideas column for Wired.

The rollout should include energy sources that we already know how to build—like solar and wind — but also experimental emerging sources such as geothermal and small nuclear, and cutting-edge forms of energy storage or transmission.

Today’s U.S. commercial nuclear power plants are fueled with uranium dioxide pressed into cylindrical ceramic pellets—and have been for decades. These pellets are stacked inside long fuel rods made of a zirconium alloy cladding. Innovation in nuclear fuel, however, can improve safety, reduce operating costs, and further enable the development of a new generation of non-light-water reactors.

According to the U.S. Energy Information Administration’s latest inventory of electric generators, 9.1 gigawatts (GW) of electric generating capacity is scheduled to retire in 2021.

In total, it appears that 30 plants (nuclear, coal, petroleum, and others) will be retired in 2021. Five nuclear reactors are included in the closure list—Indian Point-3, Byron (two units at the plant), and Dresden (two units at the plant). Those three plants produce 5.1 GW of power, accounting for more than half of the total capacity expected to be retired.

Communities across the United States where nuclear power plants have been shut down face huge gaps in tax revenues, sometimes in the tens of millions of dollars. States such as New Jersey, Illinois, Wisconsin, and California are watching events in New York now that Gov. Andrew Cuomo has signed a new law that says cities can “assess the economic value of storing waste” on sites where nuclear plants once operated, as reported by Bloomberg.

Here is a look back at the top stories of 2020 from our Power and Operations section in Newswire and Nuclear News magazine. Remember to check back to Newswire soon for more top stories from 2020.

• Defense Department invests in three microreactor designs: Three reactor developers got a boost on March 9 when they each were awarded a contract from the U.S. Department of Defense to design a reactor that can fit inside a standard shipping container for military deployment. Read more.

Crane

Christopher Crane, president and chief executive officer of Exelon, wrote in a Chicago Sun-Times op-ed, “The failure of national energy markets to support clean energy will soon force the premature retirement of two of [Illinois’s] six zero-carbon nuclear plants, putting thousands of people out of work, raising energy costs, and taking us decades backward in the fight against climate change."

Crane urged Illinois policymakers to act quickly, as they face critical decisions about the future of energy that will affect the state’s environment, the economy, and the health of every family for years to come.

Researchers at the Massachusetts Institute of Technology and Exelon show that by turning the nuclear fuel assembly design process into a game, an artificial intelligence system can be trained to generate dozens of optimal configurations that can make each fuel rod last about 5 percent longer, saving a typical power plant an estimated $3 million a year, the researchers report.

The AI system can also find optimal solutions faster than a human and can quickly modify designs in a safe, simulated environment. The results appear in the journal Nuclear Engineering and Design.

The COVID-19 pandemic hit the United States on a wide basis in March of this year, and life as we knew it changed. “Social distancing” and “essential workers” entered the jargon and working from home for many became the norm.

The number of remote meetings skyrocketed, and various companies have seen that business can be conducted without having employees in the office.

For universities, distance learning has been common for a while now, but with COVID it has become essential.

Nuclear News asked some nuclear engineering professors about how their programs have been dealing with the pandemic. We posed three questions and asked for responses to any or all of them:

How has COVID affected your NE program, and what have you learned from the experience?

Has your NE program been able to contribute to your university’s broader COVID response (e.g., through research or volunteer programs)?

What opportunities or challenges do you foresee in the next year for your program and your students?

The following are responses received by NN.

The completion of a study assessing the feasibility of deploying a fleet of GE Hitachi Nuclear Energy’s (GEH) BWRX-300 small modular reactors in Poland was announced recently by the Polish firm Synthos Green Energy (SGE).

The feasibility study, which was prepared by Exelon Generation, was not made publicly available by SGE. The study covers the analysis of key aspects of SMR technology implementation, including cost issues, personnel policy, regulatory and security issues, construction models, and operational issues, according to SGE.

SGE is a subsidiary of Synthos S.A., a manufacturer of synthetic rubber and one of the biggest producers of chemical raw materials in Poland. According to SGE, it views SMR technology as an opportunity for the deep decarbonization of Polish industry and the country's heating sector.

Chesney

An Illinois lawmaker is hopeful that legislation is coming in the state that would benefit nuclear power plants. “I believe we’re going to have an incentive program that will be in partisan legislation,” said Andrew Chesney, Illinois state representative for the 89th District.
