Content:
Branch (CMEB) verifies the capability of the DWMS to chemically process raw water to provide reactor coolant purity water for makeup to the reactor coolant system and associated systems and to provide demineralized water to other systems as required as part of its primary review responsibility for SRP Sections 5.4.8, 9.3.4 and 5.4.2.1 (BTP-MTEB 5-3). The reviews for 9.2.3-2 Rev. 2 - July 1981 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 the responsi- bility of other branches, the acceptance criteria and their methods of application are contained in the SRP sections identified as the primary review responsibility of those branches. II. ACCEPTANCE CRITERIA Acceptability of the design of the DWMS, as described in the applicant's safety analysis report (SAR), is based on design criteria or regulatory guides that apply directly to the safety-related functional performance requirements for the DWMS. The ASB assures that the system is capable of providing the required supply of reactor coolant purity water to all systems. Several general design criteria and regulatory guides are used to evaluate the system design for those cases when a failure or malfunction of the DWMS could adversely effect essential systems or components (i.e., those necessary for safe shutdown or accident prevention or mitigation). These are as. follows: 1. General Design Criterion 2, "Design Bases for Protection Against Natural Phenomena," as related to the safety-related portions of the system being capable of withstanding the effects of earthquakes. Acceptance is based on meeting the guidance of Regulatory Guide 1.29, Position C-l, if any portion of the system is deemed to be safety related, and Position C-2
