Content:
the system to function as intended under accident conditions. To assure structural integrity and leaktightness, operability and per- formance of active components, and the capability of the system to function as intended, the diesel engine cooling water system has provisions to permit periodic inspection and functional testing during standby and normal modes of power plant operation. The staff.concludes that the design of the diesel engine cooling water system conforms to all applicable GDCs, positions of the regulatory guides cited, NUREG/CR-0660, staff positions, and industry standards, and is therefore acceptable. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regard- ing the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced regulatory guides and NUREG. VI.
