Holtec SMR-300 testing facility progresses at INL
Holtec has announced it is advancing with component fabrication for a testing facility at Idaho National Laboratory that it will use to quantify performance margins of its SMR-300 pressurized water reactor. The facility, dubbed HI-TEST, will use test loops to replicate accident scenarios and steam generator behavior, aiming also to support future power uprating for SMR-300 units.

CASL is the first U.S. Energy Innovation Hub connecting fundamental research and technology development through an integrated partnership of government, academia, and industry. CASL.s objective is to provide leading edge modeling and simulation (M&S) capability to improve the performance of currently operating light water reactors and its vision is safer and more productive commercial nuclear power production afforded through comprehensive science-based predictive M&S technology. Towards that end, CASL is developing the Virtual Environment for Reactor Applications (VERA). VERA software simulates nuclear reactor physical phenomena using coupled multi-physics models and includes a range of physical domains, from microscale to engineering scale. VERA's current physics capabilities include neutron transport, thermal-hydraulics, fuel performance, and coolant chemistry.
