ow the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. The requirements of General Design Criteria 10, 20, and 25 concerning the specified acceptable fuel design limits are assumed to be met for this event when: 1. The thermal margin limits (departure from nucleate boiling ratio for PWRs) as specified in SRP Section 4.4, subsection II.1, are met. 2. Fuel centerline temperatures as specified in SRP Section 4.2, subsection II.A.2(a) and (b), do not exceed the melting point. 3. Uniform cladding strain as specified in SRP Section 4.2, subsection II.A.2(b), does not exceed 1%. 15.4.3-4 Revision 3 - March 2007 Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. 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 effects and consequences of a control rod misoperation due to system malfunction or operator error for a BWR or a PWR to ensure that specified acceptable fuel design limits are not exceeded during normal operation, including the effects of AOOs. This SRP section and SRP Sections 4.2, 4.3, 4.4, 7.2, 7.7, 15.4.1, and 15.4.2 provide guidance for ensuring that instrument setpoints are initially within and remain within the technical specification limits, thereby ensuring that specified acceptable fuel design limits are not exceeded. Meeting the requirements of GDC 10 provides reasonable assurance that specified acceptable fuel design limits are not exceeded during either normal operations or AOOs (e.g., control rod misoperation)
