  • The NRC's regulations [10 CFR 50.55a(b)(2)(xxxii)] give U.S. nuclear power plants 90 days after a refueling outage to submit an "Owner's Activity Report" (OAR-1) described in the American Society of Mechanical Engineers Boiler and Pressure Vessel Code, Section XI.

  • This is an administrative reporting requirement for items from the in-service inspection that require evaluation and repair and replacement items that occurred during the refueling outage needed for continued service.

  • The NRC staff will consider deferrals of Form OAR-1 for up to 90 days after the COVID-19 public health emergency is ended, but in no case later than the beginning of the subsequent refueling outage, provided that alternate record retention procedures are in place during the period of deferral.

Related Communication

  • The NRC issued a letter on April 9, 2020, with requirements for an expedited review of deferral requests consistent with 10 CFR 50.55a(z)(2) due to the COVID-19 public health emergency.
