FREC-II: An upgrade to SNL's Annular Core Research Reactor

Conference · · Transactions of the American Nuclear Society, Supplement
OSTI ID:5322533

The fuel-ringed external cavity, version II (FREC-II), is a recent upgrade to the annular core research reactor (ACRR) at Sandia National Laboratories (SNL). The FREC-II is neutronically coupled to the ACRR, a 2-MW steady-state/300-MJ pulse reactor used for a variety of simulation experiments in areas such as reactor safety and weapons effects. The FREC-II was designed to provide a large-volume irradiation cavity for fissile and electronic weapon components while retaining the performance characteristics of its smaller predecessor FREC-I.
