The Annular Core Research Reactor at Sandia National Laboratories recently completed its 10,000th reactor pulse operation. The ACRR has been supporting weapons certification for more than 30 years. The first pulse was conducted in April 1979. The ACRR provides unique support to the NNSA and is the only reactor of its kind in the world with its special ceramic fuel rods. Since the shutdown of the Sandia Pulsed Reactor, ACRR has been a key component for qualification alternatives. The environmental testing performed at ACRR enables NNSA to be able to certify weapons systems with confidence each year without underground testing.
