The Nuclear Company forms partnership with University of South Carolina
The Nuclear Company, which in April opened its primary engineering and construction office in Columbia, S.C., announced a partnership with the University of South Carolina’s Molinaroli College of Engineering and Computing, whereby the company will invest up to $5 million in the college over five years. USC is to match the private investment with funds from federal grants, industry partners, and other donors.

The Kilowatt Reactor Using Stirling TechnologY (KRUSTY) was a prototypic nuclear-powered test of a 5-kW(thermal) Kilopower space reactor. This paper presents results from the KRUSTY nuclear system test, which operated the power system at various temperatures and power levels for 28 consecutive hours. The testing showed that the system operated as expected and that the reactor is highly tolerant of possible failure conditions and transients. The key feature demonstrated was the ability of the reactor to load-follow the demand of the power conversion system. The thermal power of the test ranged from 1.5 to 5.0 kW(thermal), with a fuel temperature up to 880°C. Each 80-W(electric)–rated Stirling converter produced ~90 W(electric) at a component efficiency of ~35% and an overall system efficiency of ~25%.
