acceptable. * For components in the low safety-significance category, the licensee will either continue to test these components in accordance with the current ASME Code of record for the facility or has proposed an alternate test strategy that is acceptable to the staff. * LSSC that will be tested less often than required by the current code may be tested at an extended interval, in a step-wise manner, only if the interval can be justified on the basis of previous component performance. An acceptable approach is to group similar components and test them on a staggered basis. Corrective action procedures will ensure that the licensee evaluates and corrects failures or nonconforming conditions that may apply to other components in the group. The staff found that component grouping was consistent with the guidance provided in NRC Generic Letter 89-04, Position 2 for check valves; Supplement 6 to NRC Generic Letter 89-10 for motor- operated valves; or other documents endorsed by the NRC. * The licensee has developed plant corrective action and feedback procedures to ensure that testing failures are reevaluated for possible adjustment to the component's grouping and test strategy. 2. Performance Monitoring of IST Component The reviewer should verify that sufficient information is provided in accordance with the requirements herein and that the evaluation supports conclusions of the following type, to be included in the staffs safety evaluation report: * A performance monitoring program exists that covers all components in the RI-IST program. * The program responds to the attributes specified in Section II.B.2. * The licensee is committed to maintain the program as part of its RI-IST initiative. 3. Feedback and Corrective Action Program The reviewer should verify that the licensee provided sufficient information in accordance with the guidance herein and that the evaluation supports conclusions of the following type, to be included in the staffs safety evaluation
