NRC requirements such as 10 CFR 50.54(q). DG-1324, Page 8 C. STAFF REGULATORY GUIDANCE 1. General Guidance 1.1 Relationship between 10 CFR 50.54(q) and the NRC’s Reasonable Assurance Finding a. The NRC’s emergency preparedness requirements in 10 CFR 50.47(a) preclude the issuance of an operating or combined license if the NRC cannot make a finding that it has reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency. Once an operating license is issued, the licensee is required to maintain the effectiveness of its emergency plan (10 CFR 50.54(q)(2)). The emergency preparedness cornerstone of the ROP evaluates whether the licensee continues to be capable of implementing adequate protective measures. A permanently shutdown plant will transition from the ROP to an inspection program described in Inspection Manual Chapter (IMC) 2561, “Decommissioning Power Reactor Inspection Program” (Ref. 8). In either case, if at any time after the license is issued, the NRC determines that the licensee’s state of emergency preparedness does not offer such assurance and the licensee does not correct the deficiency within 4 months, the Commission will determine whether the plant will be shut down or whether other enforcement actions would be appropriate (see 10 CFR 50.54(s)(2)(ii)). b. Some changes that a licensee may make to its approved emergency plan warrant prior NRC approval to ensure that the changes would not adversely affect the NRC’s reasonable assurance determination. However, other general types of changes may have such a minimal effect on this determination that they would not warrant prior NRC approval. For example, changes that reduce the number of personnel available to respond to emergencies or lengthen the time it takes to staff and activate emergency response facilities (ERFs) could affect the NRC’s reasonable assurance determination and would require prior NRC staff approval.
