Nuclear News

On December 16 the Department of Energy reversed a decision made nearly 70 years ago by leaders of its predecessor agency, the Atomic Energy Commission, to revoke the security clearance of J. Robert Oppenheimer, the scientist who led the first group of scientists and engineers at what would eventually become Los Alamos National Laboratory as they built the first atomic bomb. While it comes far too late for Oppenheimer, his family, and his colleagues to appreciate, the McCarthy-era campaign to discredit Oppenheimer is now itself officially discredited as “a flawed process that violated the Commission’s own regulations,” in the words of the DOE’s recent announcement.

Oppenheimer’s story has been told many times by biographers and chroniclers of the Manhattan Project; a new feature film is expected in July 2023. Today, we offer a #ThrowbackThursday post that examines the scant coverage of Oppenheimer’s life and work in the pages of Nuclear News to date and draws on other historical content—and the DOE’s recent move to correct the record—to fill a few of the gaps.

Holtec International is apparently not ready to give up on the Palisades nuclear power plant just yet. Despite having been denied federal funds last month for a possible reopening of the Covert, Mich., facility, the company this week announced its intention to reapply.

For the first time ever, the Department of Energy’s Nuclear Energy University Program (NEUP) is funding research that looks at sociotechnical issues regarding the siting of nuclear power plants and spent nuclear fuel storage facilities. A number of questions at the intersection of social and nuclear concerns are being examined. How does the siting of nuclear power plants affect traditionally disadvantaged communities? How can communities have a greater voice in nuclear facility siting and development decisions? What are the livability needs for small communities experiencing an influx of engineers during the development process? At what points throughout the design and development process should decision makers incorporate social and environmental justice considerations?

The Nuclear Regulatory Commission has accepted an application from X-energy's fuel subsidiary, TRISO-X LLC, for a proposed TRISO-X Fuel Fabrication Facility (TF3) in Oak Ridge, Tenn., X-energy announced last week. A 30-month review schedule has been developed by the NRC that would be completed by June 2025, assuming TRISO-X provides sufficient responses to expected requests for additional information (RAIs) within 30 to 60 days of their issuance. On December 16, the NRC announced that it would seek public input on the scope of its environmental review and environmental impact statement for the application and published a notice in the Federal Register.

How to characterize a tight-knit, high--functioning workplace is an open question. Some consider it a family, due to close working relationships and long hours spent together. Personally, I prefer to focus on the parallels between a group of coworkers and a professional sports team.

Being a good Texan, football is my go-to for sports analogies. A football team, while cohesive, is really made up of several smaller teams. Not everyone is on the field at once, nor are the positions interchangeable. They share a goal—to win—but each smaller team has a different focus and specific tasks to achieve the goal. At a nuclear power plant, there are several departments, each also with a distinct focus but overall contributing together to the goal of reliable, safe, carbon-free energy.

Westinghouse Electric Company and Polish utility Polskie Elektrownie Jądrowe have signed an agreement defining the main principles and path forward for Poland’s first nuclear power reactors, the companies jointly announced last week.

The agreement, signed December 15, outlines next steps for the project, including site layout, licensing and permitting support, and site development services and procurement, and establishes the framework for future project delivery contracts. Another agreement is expected to be signed by mid-2023 for the design of the facility.

Context: In October, Poland chose Westinghouse to supply the reactors for its first nuclear power plant, as the Central European nation seeks to lessen its dependence on domestic coal and Russian imports for its energy supply. Competing with Westinghouse for the job were Électricité de France and Korea Hydro & Nuclear Power.

On December 5, researchers at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory achieved fusion energy breakeven. It was a gain for stockpile stewardship that also—as headlines gushed prior to the Department of Energy’s December 13 announcement—boosted the prospects of inertial fusion energy (IFE). The timing of the landmark achievement may have been especially welcome to private fusion companies with inertial or hybrid magneto-inertial confinement concepts, because it occurred as the DOE was getting ready to consider applications for $50 million in funding for fusion pilot plant design work.

TerraPower, the advanced nuclear company backed by Bill Gates, announced last week that the start date for its Natrium reactor has been pushed back. As Russia is currently the only commercial source of the high-assay low- enriched uranium (HALEU) the plant requires, the company faces a lack of fuel availability. TerraPower originally planned to use Russian fuel to get its demonstration reactor up and running by 2028, but Russia’s invasion of Ukraine has dashed those plans.

A bipartisan group of senators sent a letter last week to Scott Nathan, chief executive officer of the U.S. International Development Finance Corporation (DFC), urging the agency to begin financing nuclear energy projects and support the continued development and deployment of advanced nuclear technology.

Signing the December 8 letter were Sens. John Barrasso (R., Wyo.), Cory Booker (D., N.J.), Shelley Moore Capito (R., W.Va.), Ben Cardin (D., Md.), Chris Coons (D., Del.), Kevin Cramer (R., N.D.), Joe Manchin (D., W.Va.), Lisa Murkowski (R., Alaska), and Jim Risch (R., Idaho).

Since the inception of commercial nuclear power in the United States, every control room in every nuclear plant has looked essentially the same. You will see fixed alarm tiles, red and green lights, rows of switches, and analog meters. Until about a decade ago, you would even have seen paper charts (now replaced by digital versions of those same charts). Licensed operators have shown through a proven operating history that this control room design is safe and effective. Genius definitely went into the complexity of circuits and placement of switches and indications in the design, but things have come a long way over the years, and new technology, updated plant designs, and the need to improve efficiency and maintain reliability have impacted staffing and the role of operators. A control room update is long overdue. So, what lies ahead for the future of nuclear control room design? What possibilities exist for the next generation of plants?

The International Nuclear Energy Act (S. 4064), a bill aimed at developing a strategy to counter the growing influence of Russia and China on the global nuclear export market, was reported favorably out of the Senate Foreign Relations Committee on December 7.

The measure was introduced in April by Sens. Jim Risch (R., Idaho), the committee’s ranking member, and Joe Manchin (D., W.Va.), chairman of the Senate Energy and Natural Resources Committee.

While it currently has the lowest installed nuclear capacity of any nuclear-powered nation in Europe with one 482-MWe pressurized water reactor at Borssele, the Netherlands has in recent years been looking to move up in the rankings.

A technology developed to prevent poachers from killing endangered African species is being adapted by researchers at Oak Ridge National Laboratory to recognize individual motor vehicles. The capability could help secure checkpoints and track nuclear materials, among other uses.

Two previously radioactive structures have been successfully entombed at the Department of Energy’s Savannah River Site in South Carolina. The DOE’s Office of Environmental Management and the Savannah River Mission Completion (SRMC), the DOE’s liquid waste contractor at SRS, placed concrete over and around two concrete structures—called diversion boxes—that contain a series of connection points that allowed high-level radioactive waste to be transferred from one tank or facility to another.

The two boxes have been out of service for more than 30 years. As part of the closure process, both structures were previously filled with grout, rendering them inoperable.

The boxes were the first ancillary structures closed in this way under SRMC’s liquid waste contract. They are located in the F Tank Farm, a grouping of large underground waste-storage tanks. The liquid waste program at SRS has closed eight of the site’s 51 massive waste tanks by filling them with cementitious grout.

It’s official: Early in the morning on December 5 at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), the laser-triggered implosion of a meticulously engineered capsule of deuterium and tritium about the size of a peppercorn yielded, for the first time on Earth, more energy from a fusion reaction than was delivered to the capsule. The input of 2.05 megajoules (MJ) to the target heated the diamond-shelled, spherical capsule to over 3 million degrees Celsius and yielded 3.15 MJ of fusion energy output. The achievement was announced earlier today by officials and scientists representing the Department of Energy and its National Nuclear Security Administration, the White House, and LLNL during a livestreamed event.

Meteorological winter is here, and a chill is gripping northern Europe. Predictably, renewable generation has entered a seasonal lull and heating demand is up, despite a push to conserve natural gas, which means electricity and gas bills are up too. With a grudging nod to reality, German chancellor Olaf Scholz ensured in October that Germany’s three remaining nuclear power reactors will provide a few more months of clean, reliable power. Their premature closure, once scheduled for December 31, is now expected by April 15, 2023.

In late 2015, we heard rumors that Diablo Canyon was under threat of premature closure. As details emerged, we realized the situation was dire—similar stories were emerging around the country and the world. Nuclear plants were shutting down early for reasons that had nothing to do with plant conditions or operations, but because of politics and poor public perception.

We started brainstorming possible ways we could help, then realized our efforts had to be about more than just one plant. We knew we were in a bit of a unique position. There aren’t a whole lot of women in our industry—­especially not hippie environmentalist moms. Our story is interesting in that we were initially skeptical about nuclear power, asked questions over many years, and eventually changed our minds to support it.

Unit 1 at South Korea’s Shin-Hanul nuclear power plant entered commercial operation last week, Korea Hydro & Nuclear Power has announced. The 1,340-MWe APR-1400—designed by KHNP and parent firm Korea Electric Power Company—achieved initial criticality on May 22 of this year and was connected to the grid on June 9.

Cold hydro testing of Unit 4 at the Vogtle plant’s nuclear expansion site has been completed, Georgia Power announced on December 7.

Nuclear Newswire is back with the final #ThrowbackThursday post honoring the 80th anniversary of Chicago Pile-1 with offerings from past issues of Nuclear News. On November 17, we took a look at the lead-up to the first controlled nuclear chain reaction and on December 1, the events of December 2, 1942, the day a self-sustaining nuclear fission reaction was created and controlled inside a pile of graphite and uranium assembled on a squash court at the University of Chicago’s Stagg Field.
