wer) required for proper operation as part of their primary review responsibility for SRP Sections 7.1 and 8.0, respectively. The Containment Systems Branch (CSB) reviews the MSIVLCS to assure that no malfunction can adversely affect containment integrity as part of its primary review responsibility for SRP Sections 6.2.1 and 6.2.4. The review for fire protection, technical specifica- tions, 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 responsibility for SRP Sections 9.5.1, 16.0, and 17.0, respectively. For those areas of review identified above as being the responsibility of other branches, the acceptance criteria and their methods of application are contained in the SRP sections corresponding to those branches. II. ACCEPTANCE CRITERIA Acceptability of the MSIVLCS, as described in the applicant's safety analysis report (SAR), is based on specific general design criteria and regulatory guides. An additional basis for determining the acceptability of the MSIVLCS is the degree of similarity of the design with that of previously reviewed plants. The design of the MSIVLCS is acceptable if the integrated system design is in accordance with the following criteria: 1. General Design Criterion 2, as related to structures housing the system and the system itself being capable of withstanding the effects of earth- quakes. Acceptance is based on meeting position'C.1 of Regulatory Guide 1.29 and position C.1 of Regulatory Guide 1.96. 6.7-3 Rev. 2 - July 1981 2. General Design Criterion 4, as related to structures housing the system and the system itself being capable of withstanding the effects of pipe breaks and externally and internally generated missiles. Acceptance is based on meeting positions C.2 and C.4 of Regulatory Guide 1.96. 3. General Design Criterion 54, as related to the capability for leak detection, isolation, and performance testing
