ection 6.5.1). ETSB also reviews and evaluates the capability of the ESFVS to detect and control leakage of radio- active contamination from the system as described in SRP Section 11.5. The review for Fire Protection, Technical Specifications, and Quality Assurance are coordinated and performed by the Chemical Engineering Branch, Licensing Guidance Branch, and Quality Assurance Branch as part of their primary review responsi- bility for SRP Sections 9'.5.1, 16.0, and 17.0, respectively. For those areas of review identified above as being reviewed 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 branch. II. ACCEPTANCE CRITERIA Acceptability of the ESFVS design, as described in the applicant's Safety Analysis Report (SAR), is based on specific general design criteria and regu- latory guides. The design of safety-related portions of the ESFVS is acceptable if the inte- grated design of the systems is in accordance with the following criteria: 1. General Design Criterion 2, as related to the system being capable of withstanding the effects of earthquakes. Acceptance is based on meeting the guidance of Regulatory Guide 1.29, position C.1 for safety-related portions and C.2 for nonsafety-related portions. 2. General Design Criterion 4, with respect to maintaining environmental conditions in essential areas compatible with the design limits of the essential equipment located therein during normal, transient, and accident conditions. 3. General Design Criterion 5, as related to shared systems and components important to safety. 9.4.5-3 Rev. 2 - July 1981 4. General Design Criterion 17, as related to assuring proper functioning of the essential electric power system. Acceptance is based on meeting the guidance of item 2 under subsection A and item 1 under subsection C of the section on "Recommendations" of
