ted reactivity insertion rate for BWRs. DRAFT Rev. 2 - April 1996 15.2.1-6 c. The core burnup is selected to yield the most limiting combination of moderator temperature coefficient, void coefficient, Doppler coefficient, axial power profile, and radial power distribution. Technical Rationale32 The technical rationale for application of these acceptance criteria to reviewing analyses of reactor temperature and pressure transients at a nuclear power plant is discussed in the following paragraphs:33 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 consequences of the events specified in Regulatory Guide 1.70. Such events could result in a decrease in heat removal by the secondary system, potentially causing the thermal design criteria for the fuel cladding to be exceeded. Regulatory Guide 1.105 provides guidance for ensuring that instrument setpoints are initially within and remain within technical specification limits. Meeting the requirements of GDC 10 provides assurance that specified acceptable fuel design limits are not exceeded for initiating events involving a decrease in heat removal by the secondary system.34 2. Compliance with GDC 15 requires that the reactor coolant system and associated auxiliary, control, and protection systems shall 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 evaluates the consequences of events specified in Regulatory Guide 1.70. Such events could result in a
