From the U.S. Department of Energy Office of Nuclear Energy:

“ON THE MOVE: Westinghouse is developing eVinci — a transportable microreactor that will use advanced heat pipe technology and TRISO fuel to expand access to reliable power.
The reactor is designed to generate up to five megawatts of electricity and operate for up to eight years or longer without refueling.
Westinghouse is one of two companies selected to test its first fueled reactor experiment in DOME — the world’s first microreactor test bed at Idaho National Laboratory.”
