Annular Core Research Reactor - Critical to Science-Based Weapons Design, Certification

NNSA BlogNNSA Sandia Field Office Facility Representative Erwin Hoo provided NNSA Administrator Frank Klotz a tour of the Annular Core Research Reactor (ACRR) at Sandia National Laboratories in Albuquerque on Jan. 13.

The ACRR is a mission critical asset – the only remaining NNSA capability for high-power, short pulse environments needed to simulate nuclear weapons effects on full-scale systems. This test capability is critical to science-based weapons design and certification.

The ACRR is a pool-type research reactor (Hazard Category 2 Nuclear Facility) that has been in operation since the 1970s and has conducted more than 10,000 operations.
