w. I. 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 a reduction in occupational exposure of plant personnel in complying with the requirements. 2. 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 in a plant or to reflect equipment reliability improvements that make a previous requirement unnecessarily stringent or ineffective. TS may be changed to establish consistently based requirements across the industry or across an industry group. It must be ensured that the risk resulting from the change remains acceptable. 3. Reduce Unnecessary Burdens The change may be requested to reduce unnecessary burdens in complying with current TS requirements, based on the operating history of the plant or industry in general. For example, 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, result in unnecessary equipment wear, result in excessive radiation exposure to plant personnel, or place unnecessary administrative burdens on plant personnel that are not justified by the safety significance of the surveillance requirement. Rev. 0 - August 1998 SRI? 16.1-12 In some cases, the change may provide operational flexibility; in those cases, the modification might allow an increased allocation of the plant personnel's time to more safety-significant aspects. In some cases, licensees may determine there is a common need for a TS change among several licensees and submit the request as a group rather than individually. Group submittals can be advantageous when the SSCs being considered in the change are similar across all plants in the group. Plant specific information with regard to the engineering evaluations described in Section III.B must still
