n reviews the analysis of a group of abnormal operating occurrences to which the GDC must be applied. Meeting the requirements of GDC 17 provides assurance that specified acceptable fuel design limits and design conditions of the reactor coolant pressure boundary are not exceeded as a result of initiating events involving an increase in reactor coolant inventory, concurrent with a loss-of-offsite-power (LOOP).45 4. Compliance with GDC 26 requires that the reactivity control system utilizing control rods be capable of reliably controlling reactivity changes to ensure that, under anticipated 15.5.1-7 DRAFT Rev. 2 - April 1996 operational occurrences and with appropriate margin for malfunctions such as stuck rods, fuel design limits are not exceeded. The requirements of GDC 26 apply to this section because the reviewer looks at certain events occurring with moderate frequency and having the potential to result in exceeding fuel design limits. The reviewer, in conjunction with the HICB reviewer implementing SRP Chapter 7, determines that the design parameters of the reactivity control system are sufficient to control the reactivity changes resulting from the anticipated operational occurrences. Meeting this criterion provides assurance that anticipated operational occurrences will not result in fuel damage and subsequent fission product release.46 III. REVIEW PROCEDURE The procedures below are used during both the construction permit (CP) and operating license (OL) reviews During the CP review, the values of system parameters and setpoints used in the analysis will be preliminary in nature and subject to change. At the OL review, final values should be used in the analysis, and the reviewer should compare these to the limiting safety system settings included in the proposed technical specifications. The applicant's description of events leading to an increase in reactor coolant inventory is reviewed by RSBSRXB regarding the occurrences leading to the initiating event.
