NIST reactor remains shut down as NRC investigates radiation release

Neutron measurement studies at the NIST Center for Neutron Research (NCNR) are on hold for an investigation of a different sort. On February 9, less than a week after elevated radiation levels were detected as the NCNR research reactor was powered up following a scheduled maintenance outage, the Nuclear Regulatory Commission began an inspection at the facility. According to NIST, the reactor will remain shut down until the cause of the release is corrected.

“The first step will be to develop a plan for safely assessing the condition of the reactor so that the root cause of the elevated radiation levels can be investigated,” NIST announced on February 5. “Once that root cause is determined, NIST will identify and then implement all necessary corrective actions.”
