ent as part of its primary review responsibility for SRP Section 3.6.1. The Reactor Systems Branch (RSB) determines that the steam bypass capacity is consistent with reactor transient analysis as part of its primary review responsibility for SRP Section 4.4. The Procedures and Test Review Branch determines the acceptability of the preopera- tional and startup tests as part of its primary review responsibility for SRP Section 14.0. The reviews 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 responsibility for SRP Sections 9.5.1, 16.0, and 17.0, respectively. For those areas of review identified above as being 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 sections of the corresponding primary branches. II. ACCEPTANCE CRITERIA Acceptability of the design of the turbine bypass system, as described in the applicant's safety analysis report (SAR), is based on the specific General Design Criteria, industry standards, and other criteria listed'below and on the similarity of the design to that of plants previously reviewed and found acceptable. The design of the turbine bypass system is acceptable if the integrated design of the system is in accordance with the following criteria: 1. General Design Criterion 4 in that failure of the TBS due to a pipe break or malfunction of the TBS should not adversely affect essential systems or components (i.e., those necessary for safe shutdown or accident preven- tion or mitigation). 2. General Design Criterion 34 as related to the ability to use the system for shutting down the plant during normal operations. The operation of the TBS eliminates the need to rely solely on safety systems which are required to meet the redundancy and
