nto one or more of the following categories: A. Improvement in Operational Safety. The reason for the TS modification may be to improve operational safety; that is, a reduction in the plant risk or in occupational exposure of plant personnel complying with the requirements. B. Consistency of Risk Basis in Regulatory Requirements. The TS modifications requested can be supported on their risk implications. TS requirements can be changed to reflect improved design features or equipment reliability improvements that make a previous requirement unnecessarily stringent or ineffective. TSs may be changed to establish consistent requirements across the industry or an industry group. The risk from the change must remain acceptable. C. Reduce Unnecessary Burdens. The change may be requested to reduce unnecessary burdens of compliance with TS requirements based on plant-specific or industry operating history. In specific instances, the repair time needed may be longer than the AOT defined in the TS. The required surveillance may lead to plant transients, unnecessary equipment wear, excessive radiation exposure to plant personnel, unnecessary administrative burdens not justified by the safety significance of the surveillance requirement. The change may increase operational flexibility or allow an increased allocation of plant personnel time to more safety-significant aspects. In some cases, several licensees may determine there is a common need for a TS change and submit the request as a group. Group submissions can be advantageous when the SSCs considered in the change are similar across all plants in the group. Plant-specific information as to the engineering evaluations described in Section III.2 of this SRP section still is required; however, the group may be able to draw generic conclusions from a compilation of the plant-specific data. In addition, there are benefits from cross-comparison of the results of the plant-specific evaluations. 2. Perform Engineering Analysis A.
