NASA’s Artemis I mission, successfully launched at 1:47 a.m. EST on November 16 from the Kennedy Space Center in Florida, will travel 40,000 miles beyond the moon—farther from Earth than any human-crewed space mission has flown before. The historic trip was launched by the world’s largest rocket, the Space Launch System (SLS), nearly 50 years after NASA last sent humans to the moon. And while no humans are on board the Orion spacecraft, two fabricated crew members—“Luna Twins” Helga and Zohar—were assembled with thousands of sensors to obtain the best estimates yet of cosmic radiation exposure to human tissues during space travel.

As we approach the 80th anniversary of controlled nuclear fission, Nuclear Newswire is prepared to deliver not one but three #ThrowbackThursday posts of CP-1 highlights unearthed from past issues of Nuclear News.
ANS was founded in 1954, nearly 12 years after the first controlled nuclear chain reaction was achieved on December 2, 1942, inside a pile of graphite and uranium assembled on a squash court at the University of Chicago’s Stagg Field. By 1962, ANS was prepared to “salute the 20th anniversary of the first chain reaction” at their Winter Meeting, displaying a model of Chicago Pile-1 and presenting a specially cast medal to Walter Zinn, a representative of Enrico Fermi’s scientific team. Over the years, ANS has continued to mark significant anniversaries of CP-1 at national meetings and in NN.

Canadian Nuclear Laboratories (CNL) and General Fusion have announced a memorandum of understanding (MOU) to “develop fusion energy research capabilities within CNL, to support the goal of constructing a potential General Fusion commercial power plant in Canada before 2030.” The plant would follow on a demonstration-scale plant that General Fusion wants to have operating in the United Kingdom by 2027 to validate the performance and economics of the technology.

The Export-Import Bank of the United States has issued two letters of interest (LOIs) for the financing of U.S.-sourced pre-project technical services in connection with the proposed reactor construction project at Romania’s Cernavoda nuclear plant, the bank announced last week.

The Department of Energy announced a cost-shared award on November 10 valued at about $150 million for American Centrifuge Operating, a subsidiary of Centrus Energy, to complete the high-assay low-enriched uranium (HALEU) demonstration project it began in 2019. After delays that Centrus attributes in part to the COVID-19 pandemic, the company now has until the end of 2023 to produce the first 20 kilograms of HALEU enriched to 19.75 percent U-235 from the 16-centrifuge cascade it has installed in a DOE-owned Piketon, Ohio, facility—the only U.S. facility currently licensed to produce HALEU.

The Department of Energy’s Office of Environmental Management (EM) said its cleanup contractor UCOR recently completed the first-ever demolition of a reactor in the central campus area at the Oak Ridge National Laboratory in Tennessee.
Demolition and disposal shifted into high gear this spring at the DOE’s former uranium enrichment plant in Ohio.
In the 1950s, the U.S. Department of Energy constructed the Portsmouth Gaseous Diffusion Plant in rural southern Ohio to enrich uranium, alongside two other federally owned and managed facilities in Oak Ridge, Tenn., and Paducah, Ky. The Cold War-era plant was built as a self-sufficient industrial city with more than 400 buildings and facilities centered around three massive gaseous diffusion process buildings that could enrich the level of the uranium-235 isotope for nuclear fuel in the defense and energy sectors.

The Steam Generating Team (SGT)—a joint venture of Framatome and United Engineers & Constructors Inc.—has completed a project to replace the Unit 2 steam generators at the Watts Bar nuclear plant, Framatome announced last week.
Watts Barr’s owner and operator, the Tennessee Valley Authority, awarded Framatome the contract for the work in early 2020.

The United Nations’ COP27 conference, held this year in Sharm el-Sheikh, Egypt, from November 6 to 18, will feature the panel discussion “Energy Security” on Tuesday, November 15, at 9:00 a.m. EST (4:00 p.m. local time). The discussion is being sponsored by the review platform We Don’t Have Time; the live stream will be available to viewers on their COP27 Climate Hub website.

The Nuclear Energy eXperimental Testing (NEXT) Laboratory at Abilene Christian University in Texas created quite a bit of buzz within the nuclear community in August when it submitted the first application for a new U.S. research reactor in more than 30 years. The construction permit application submitted to the Nuclear Regulatory Commission is for a molten salt research reactor (MSRR)—the first-ever university application for an advanced research reactor. Assuming NRC acceptance of the application, which could happen this year, a formal technical review of the lab’s MSRR plan will then begin, and construction of the MSRR could be completed by 2025. The Abilene campus’s new Science and Engineering Research Center—a 28,000-square-foot multiuse facility for chemistry, physics, and engineering research and education—is expected to be completed by July 2023 and will house the advanced reactor. The final step is to obtain the NRC operating license for the MSRR and commence operation.

While deep geological repositories (DGRs) are the globally preferred and scientifically proven solution to store high-level radioactive waste, societal challenges remain. Given the long time frames associated with DGR development and implementation, and a rise in global interest in nuclear energy to meet urgent climate mitigation targets, building and maintaining human capacity is now even more of a priority.
