whether it will find the change acceptable if the licensee submits it for review. Licensees should arrange a conference call with NRC headquarters for the following types of changes to their emergency plans: (1) changes that increase the activation time of licensee ERFs or a change in how the activation time is measured (e.g., when the activation period starts and when it ends), either of which results in a delay in those facilities’ provision of meaningful support to the control room consistent with the facilities’ assigned functions and responsibilities; (2) changes to ERO staffing that eliminate a key position1 or reduce the licensee’s capability to staff those positions 24 hours a day, 7 days a week (i.e., 24/7 support), consistent with the fitness-for-duty requirements in 10 CFR Part 26, “Fitness for Duty Programs”; (3) changes that combine the plant-specific emergency plan for two or more noncontiguous plant sites into a common emergency plan; (4) changes that relocate the TSC to a location outside of the protected area for the plant site; and (5) any change to the current NRC-approved emergency plan for decommissioning plants for which the 10 CFR 50.54(q)(3) reduction in effectiveness evaluation relies, in part or in whole, on the permanent cessation of operations or on changes put into place under the authority of other change processes (e.g., 10 CFR 50.59, 10 CFR 50.48(f)). 3. Emergency Plan Change Evaluation Terminology This section provides a definition and discussion of key terms used in evaluating changes in an emergency plan. These definitions are ordered such that each definition builds on the preceding definitions. 1 Key positions include those in the (1) control room (shift manager (emergency director) and shift communicator), (2) TSC (senior manager, operations support, radiological controls, TSC communicator, and technical support), (3) EOF (senior manager, protective measures, and EOF communicator), and (4) OSC (OSC operations manager).
