The electric power transmission grid of the U.S. consists of thousands of miles of lines operated by hundreds of companies.
To do big things, like building the interstate highway system, or going to the moon, government usually has a plan. Electric companies and grid operators, which are responsible for keeping the lights on, always have a plan. But something unusual has happened in the past few months. About four dozen U.S. utilities, plus the federal government and many states, have promised to do something extremely big: to eliminate carbon dioxide emissions, or cut them drastically. But they are not clear on how.

The Texas A&M Engineering Experiment Station (TEES) has installed the NuScale small modular reactor control room simulator at the Center for Advanced Small Modular and Micro Reactors (CASMR).
TEES performs collaborative research through universities, national laboratories, and state and federal agencies with the goal of finding solutions to global technical challenges.

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.

The Department of Energy’s Office of Environmental Management (EM) is set to complete the 69th building demolition at the West Valley Demonstration Project early next year, when crews finish knocking down the last structure standing that supported operations at the former Main Plant Process Building.
