0 CFR 50.54(q)(2), the licensee should minimize the duration of the outage, or carry out viable compensatory measures. The 10 CFR 50.54(q)(3) process does not apply in these cases unless the emergency plan is changed to carry out short-term or long-term corrective actions.4 e. “Resources” mean personnel, procedures, equipment, communications, instrumentation, analytical equipment, transportation, supplies, and other items needed to carry out the response actions identified in the emergency plan. “Capabilities” means the capacity to put into place the response actions identified in the emergency plan (e.g., the ability to augment onshift personnel in a timely manner, generate timely and accurate PARs, complete notifications within 15 minutes, and maintain a protracted response). “Methods” means the procedural means or manner of carrying out the response actions identified in the emergency plan (e.g., emergency classification schemes, notification protocols, and emergency action level (EAL) threshold value bases). These elements are generally interdependent. For example, capability is lost if the needed resources are missing. 3.7 Reduction in Effectiveness a. “Reduction in effectiveness” means a change to an emergency plan that results in reducing the licensee’s capability to perform an emergency planning function in the event of an emergency. See 10 CFR 50.54(q)(1)(iv) for more information. b. “Reduction in effectiveness” is an evaluation concept that is used with 10 CFR 50.54(q) to differentiate between changes that a licensee is allowed to make without prior NRC approval and those that require prior NRC approval (see Regulatory Position 1.1). As used here, “emergency” means any condition that would result in the declaration of any emergency classification level and the implementation of the licensee’s emergency plan. An emergency is not based on a single accident sequence but instead on the spectrum of accidents addressed in the planning
