Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

DOE extends Centrus’s HALEU production contract by one year
Centrus Energy has secured a contract extension from the Department of Energy to continue—for one year—its ongoing high-assay low-enriched uranium (HALEU) production at the American Centrifuge Plant in Piketon, Ohio, at an annual rate of 900 kilograms of HALEU UF6. That's the same amount of HALEU—900 kg—that the company today announced it has delivered to the DOE, completing Phase II of its contract. According to Centrus, the contract extension, which allows the company to begin Phase III, is valued at about $110 million through June 30, 2026.

This paper describes an analysis of the Doppler effect of structural materials, having a possibility of the importance in fast reactor safety. The shielding factors of the effective capture cross sections are prepared for chromium, iron, and nickel based on the nuclear data of ENDF/B-II. Using these shielding factors, the Doppler experiments for stainless steel and natural iron performed in the JAERI-FCA cores are analyzed by a simple perturbation method.The computed results are in fairly good agreement with the experiment although they are a little lower. It is suggested that the lower values might be attributed to the missing level of the sharp p- and d-wave resonances above 30 keV or to neglecting the contributions from the unresolved resonances.
