The license for Pacific Gas & Electric Company’s Humboldt Bay Unit 3 nuclear power plant near Eureka, Calif., has been terminated by the Nuclear Regulatory Commission, and the site has been released for unrestricted use. A 65-MWe boiling water reactor plant, Humboldt Bay-3 operated commercially from 1963 to 1976.

The Department of Energy is funding an independent review of NuScale Power’s safety analysis report (SAR), to be conducted by Ukraine’s State Scientific and Technical Center for Nuclear and Radiation Safety (SSTC NRS), the Portland, Ore.–based small modular reactor developer announced on November 18.

The Nuclear Regulatory Commission recently issued a draft safety evaluation report indicating initial acceptance of Kairos Power’s source term methodology for its fluoride salt–cooled high-temperature reactor (KP-FHR).

ANS sponsored 10 young nuclear professionals from the Young Generation Network, a branch of the U.K.’s Nuclear Institute, to attend COP26, the 2021 United Nations climate change conference, held in Glasgow, Scotland, where they helped deliver what was “by all accounts nuclear’s best representation at the COP ever,” according to George Burnett, one of four U.K.-based attendees sponsored by ANS.

By using a combination of physics-based modeling and advanced simulations, Texas A&M University researchers say they have found the key underlying factors that cause radiation damage to nuclear reactors, which could provide insight into designing more radiation-tolerant, high-performance materials.

As a spacecraft on a research mission hurtles at up to 100,000 miles per hour toward the surface of a gas giant like Jupiter, the atmospheric gases surrounding the spacecraft turn to plasma, and spacecraft temperatures increase to more than 10,000 °F.
