ffect the ability to achieve and maintain safe shutdown. The assessment should include the effect on the fire hazards analysis and should consider whether SSCs for a success path for safe shutdown are affected or a new element is introduced in the area. If the evaluation concludes that there are no adverse effects, the licensee should document this conclusion and its basis and make it available for future inspection and reference. If the evaluation finds that there are adverse effects, or that it is outside the basis for an exemption that was granted for the area involved, the licensee should make DG-1359, Page 35 modifications to achieve conformance, justify and request an exemption, or seek a license amendment from the NRC. 1.8.1.4 Nonconforming Conditions In addition to an evaluation of planned changes, an evaluation may be required for nonconforming conditions. See Regulatory Position 1.5 for additional information on compensatory measures. In the case of a degraded or nonconforming condition, an evaluation depends on the licensee’s compensatory and corrective actions. Three potential conditions exist for determining the need for an evaluation: (1) the use of interim compensatory actions, (2) corrective actions that result in a change, or (3) corrective actions that restore the nonconforming or degraded condition to the previous condition. If the licensee takes an interim compensatory action to address the condition that falls within the scope of the standard fire protection license condition, it should conduct a review that may result in a change evaluation. The intent of the review is to determine whether the compensatory action itself (not the degraded condition) affects other aspects of the facility described in the FSAR. If the condition is accepted “as is,” resulting in something different from that described in the FSAR, or is modified to something that differs from the FSAR, the condition should be considered a change and a change evaluation should
