h regard to automatic actuation, remote sensing, indication, control, interlocks with auxiliary or shared systems, potential bypass modes, and the possibility of manual control by the operator. 2. The Power Systems Branch (PSB)Electrical Engineering Branch (EELB), upon request 18 from RSBSRXB, will verify that the control systems power sources needed to function 19 to mitigate the event are available as required by the applicant's description of the event. 3. The Equipment Qualification Branch (EQB)Plant Systems Branch (SPLB), upon the 20 request of RSBSRXB, will verify that the equipment necessary to mitigate the event is 21 qualified for the transient and post-transient environments. The EQBSPLB will also 22 identify, if requested, equipment whose failure as a result of the initiating event could adversely affect the consequences. The SPLB also reviews the integrity of the reactor coolant pump seals as part of its primary review responsibility for SRP Section 9.2.2.23 15.6.1-3 DRAFT Rev. 2 - April 1996 4. The Human Factors Assessment Branch (HHFB) evaluates plant operating procedures as part of its primary review responsibility for SRP Section 13.5.2. On request from SRXB, HHFB verifies that plant operating procedures include appropriate actions relative to a reactor coolant pump trip after the inadvertent opening of a PWR pressurizer relief valve as described in Generic Letters 85-12, 86-05, and 86-06.24 For those areas of review identified above as part of the primary review responsibility of other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary review branch. II. ACCEPTANCE CRITERIA The RSBSRXB acceptance criteria are based on meeting the relevant requirements of the 25 following regulations: A. General Design Criterion (GDC) 10 (Reference 2) (GDC 10), as it relates to the reactor 26 coolant system being designed with appropriate margin to
