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.

A water-flooded-core accident is a serious potential accident for high-temperature gas-cooled reactors (HTGRs). In this technical note, based on two different water-flooded-core scenarios, preliminary neutronics analysis was performed on a typical HTGR. Preliminary temperature-effect analysis is carried out as well. It is found that the neutron-slowing ability is the key for the effective multiplication factor of the HTGR core. More importantly, when the water-flooded-core accident occurs, the HTGR might return back to supercritical with the core temperature decreasing even if it is safely shut down at high operation temperature.
