Date Time May 6, 2021, Update on Status of NCNR Preliminary results of an ongoing internal analysis by the National Institute of Standards of Technology (NIST) indicate that inadequacies in training and procedures led to damage to a single fuel element in its research reactor, causing the Feb. 3, 2021, alert at the NIST Center for Neutron Research (NCNR). NIST has notified the Nuclear Regulatory Commission (NRC) and has already begun updating its policies and procedures to ensure these inadequacies are addressed. The findings do not change the previously reported results of the event. The public was safe at all times, and radiation levels outside the confinement building remained well below regulatory health and safety limits. The NCNR is designed to keep the public safe even in a worst-case scenario.
