CFR Title: 

Content:
f Structures, Systems and Components," for the capability of shared systems and components important to safety to perform required safety functions. Each unit of the plant has its own emergency diesel generators, each with an EDELS not shared between the diesel generators. 3. The applicant has met the requirements of GDC 17, "Electric Power Systems," for EDELS capability to meet independence and redundancy criteria. Each EDELS is independent and physically separated from the other system serving the redundant diesel generator. A single failure in any one of the systems will affect only its own diesel generator. The EDELS for each diesel engine provides the necessary engine lubrication during operation and maintains the lube oil at a temperature that improves first-start reliability. The applicant has also met the positions of NUREG/CR-0660, "Enhancement of Onsite Emergency Diesel Generator Reliability." For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable. V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for complying with specified portions of the Commission’s regulations, the staff will use the method described herein to evaluate conformance with Commission regulations. The provisions of this SRP section apply to reviews of applications submitted six months or more after the date of issuance of this SRP section, unless superseded by a later revision. VI.
