that minimum system flow and heat transfer requirements are met for each accident situation for the required time spans. For each case, the design will be acceptable if minimum system requirements are met. D. The boron recovery system is not required for safe shutdown, or for the prevention or mitigation of postulated accidents. The BRS will be reviewed for the following: if the system tankage is of nonseismic Category I design, the results of analyses which postulate the rupture of tanks are reviewed by AEB to verify that the accident releases are in accordance with safe limits. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his review supports conclusions of the following type, to be included in the staff's safety evaluation report: 9.3.4-7 Rev. 2 - July 1981 The chemical and volume control system (including boron recovery system) includes components and piping associated with the system from the let- down line of the primary system to the charging lines that provide makeup to the primary system and the reactor coolant pump seal water system. Based on the review of the applicant's proposed design'criteria, design bases, and safety'classification for the chemical and volume control sys- tem, and the requirements for system performance of necessary functions during normal, abnormal, and accident conditions, the staff concludes that the design of the chemical and volume control system and supporting system is acceptable and meets the requirements of General Design Criteria 1, 2, 5, 14, 29, 33, 35, 60, and 61. This conclusion is based on the follow- ing: the applicant's design of the chemical and volume control system meets (1) the requirements of General Design Criterion 1 and the guide- lines of Regulatory Guide 1.26 by assigning quality group classifications to system components in accordance with the importance of the safety function to'be performed; (2) the requirements of General Design Cri- terion 2 and the
