tance criteria to transients involving loss of flow is discussed in the following paragraphs:39 a. Compliance with GDC 10 requires that the reactor core and associated coolant, control, and protection systems be designed with appropriate margin to ensure that specified acceptable fuel design limits are not exceeded during any condition of normal operation, including the effects of anticipated operational occurrences. GDC 10 is applicable to this section because the reviewer evaluates the consequences of loss of forced reactor coolant flow, including a trip of pump motors and flow controller malfunctions. These are anticipated operational occurrences that create a potential to exceed specified acceptable fuel design limits because a transient reduction in reactor coolant flow causes a corresponding rise in fuel-cladding temperature. Meeting the requirements of GDC 10 provides a level of assurance that specified acceptable fuel design limits are not exceeded and that fuel-cladding integrity is maintained for anticipated operational occurrences involving loss of forced reactor coolant flow.40 b. Compliance with GDC 15 requires that the reactor coolant system and associated auxiliary, control, and protection systems be designed with sufficient margin to ensure that the design conditions of the reactor coolant pressure boundary are not exceeded during any condition of normal operation, including anticipated operational occurrences. GDC 15 is applicable to this section because the reviewer analyzes anticipated operational occurrences involving loss of forced reactor coolant flow. In these transients, a reduction in reactor coolant flow can cause the reactor coolant system pressure to increase above normal levels. Therefore, for loss-of-flow transients covered by SRP DRAFT Rev. 2 - April 1996 15.3.1-6 Section 15.3.1 – 15.3.2, the reactor coolant pressure needs to be analyzed to ensure that the pressure acceptance criterion is satisfied. Meeting the requirements of GDC 15
