Nuclear thermal propulsion (NTP) is one technology that could propel a spacecraft to Mars and back, using thermal energy from a reactor to heat an onboard hydrogen propellant. While NTP is not a new concept, fuels and reactor concepts that can withstand the extremely high temperatures and corrosive conditions experienced in the engine during spaceflight are being designed now.
BWX Technologies announced on December 13 that it has delivered coated reactor fuels to NASA for testing in support of the Space Technology Mission Directorate’s NTP project. BWXT is developing two fuel forms that could support a reactor ground demonstration by the late 2020s, as well as a third, more advanced and energy-dense fuel for potential future evaluation. BWXT has produced a videoof workers processing fuel kernels in a glovebox.

Energy secretary Jennifer Granholm toured the Braidwood nuclear plant in Illinois last week as part of a statewide tour to promote the climate provisions in the recently passed trillion-dollar infrastructure law and the Build Back Better Act, over which the Senate continues to haggle.

First-of-a-kind research reactors, demo reactors, and research facilities are being developed and sited on university campuses to support the broader deployment of advanced reactors. At the 2021 ANS Winter Meeting and Technology Expo, during a December 2 panel session titled “Research Reactors in Support of Advanced Reactor R&D,” several of these planned projects were discussed in detail—including a molten salt reactor in Texas and a high-temperature gas–cooled reactor in Illinois.
The session was sponsored by the Reactor Physics Division and organized and chaired by Pavel Tsvetkov, of Texas A&M University. A video of the session is available to registered Winter Meeting attendees.

Électricité de France recently announced the formation of an advisory board for NUWARD, France’s small modular reactor project. According to the company, the establishment of the International NUWARD Advisory Board (INAB) is a major step forward in support of the technology’s development.

The Thursday morning executive session at last week’s 2021 ANS Winter Meeting and Technology Expo brought together a group of influential nuclear-policy experts from the United States and abroad to discuss the roles nuclear can play in smoothing the pathway to net-zero emissions by 2050. Specific topics explored included the Clean Energy Ministerial (CEM) and its Nuclear Innovation Clean Energy (NICE) Future initiative, as well as last month’s COP26 climate conference in Glasgow. The session was moderated by Leah Parks, a Nuclear Regulatory Commission risk analyst and 2020 ANS Presidential Citation awardee.

Georgia Power has revised the projected commercial operation dates for Vogtle-3 and -4 a total of four times this year—most recently in October—but some experts are saying that at least one more delay is probable.

Unit B1 at Scotland’s two-unit Hunterston B nuclear power plant was taken off line for good on November 26 after nearly 46 years of operation. A 490-MWe advanced gas-cooled reactor, the unit entered commercial operation in June 1976. Its companion AGR, Unit B2, which entered operation in March 1977, is scheduled for retirement in January.

Ontario Power Generation (OPG) has selected GE Hitachi Nuclear Energy (GEH) as its technology partner for the Darlington nuclear new-build project. The companies will work to deploy GEH’s BWRX-300 small modular reactor at OPG’s Darlington nuclear plant, located in Clarington, Ontario.

The newest generation of lithium-ion batteries now being developed uses thin-film, solid-state technology and could soon safely power cell phones, electric vehicles, laptops, and other devices. However, like all batteries, solid-state lithium-ion batteries have a drawback: Impedance—electrical resistance—can build up as batteries are discharged and recharged, limiting the flow of electric current.
