ions or technical specifications that can provide adequate or equivalent protection is immediately apparent. These regulations serve to ensure that the emergency action decisions that are necessary to protect public health and safety, or the health and safety of security force personnel, are made by an individual who has both the requisite knowledge and plant experience. For a permanently shutdown and defueled reactor, the regulations require that such actions may only be approved, at a minimum, by a licensed senior operator or a CFH, as these individuals have the requisite knowledge and plant experience to evaluate plant conditions and make such emergency decisions. Command and Control At a decommissioning facility, the shift manager is often the senior technical position on site and typically has overall command and control responsibilities for the three functional capabilities discussed above. Because a CFH is also required to have training on, and is responsible for, decisions on these three functional capabilities, the shift manager is typically also qualified as a CFH. Due to the management responsibilities of the shift manager/CFH, he or she may also be one of the responsible parties to meet the communication requirements in 10 CFR 73.55(j) related to ensuring effective command and control during both normal and emergency situations, as well as to support security personnel. Staffing In response to license amendment requests from decommissioning licensees, the NRC staff has approved changes to the minimum levels for staff on shift in the administrative controls section of the plant technical specifications. These amendments have each involved replacing the SRO and RO positions with one CFH and one NLO, respectively, to perform activities involving the functions discussed above. The NRC staff recognizes that these prior approvals have addressed only a limited number of staffing scenarios that could be encountered at a decommissioning reactor, and have
