ostulated accident conditions. c. Mechanism functional tests. d. Program results. In addition, the MEB will coordinate other branches' evaluations that interface with the overall review of the CR0S as follows: The Core Performance Branch (CPB) will verify fuel system design, including effects of the CRDS on fuel behavior in meeting the requirements of the reactor core design under various normal and accident operating conditions in SRP Section 4.2. The Materials Engineering Branch (MTEB) will review the material aspects of CROS in SRP Section 4.5.1. For those areas of review identified above 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 MEB acceptance criteria are based on meeting the requirements of the following regulations: 1. GDC 1 and and 10 CFR Part 50,§50.55a, as its relates to CRDS, requires that the CRDS be designed to quality standard commensurate with the impor- tance of the safety functions to be performed. 2. GDC 2, as it relates to CRDS, requires that the CRDS be designed to with- stand the effects of-an earthquake without loss of capability to perform its safety functions. 3. GDC 14, as it relates to CRDS, requires that the RCPB portion of the CRDS be designed, constructed, and tested for the extremely low probability of leakage or gross rupture. 4. GDC 26, as it relates to CRDS, requires that the CRDS be one of the inde- pendent reactivity control systems which is designed with appropriate 3.9.4-3 Rev. 2 - April 1984 margin to assure its reactivity control function under anticipated normal operation condition. 5. GDC 27, as it relates to CRDS, requires that the CRDS be designed with appropriate margin, and in conjunction with the emergency core cooling system, be capable of controlling reactivity and cooling the core under postulated accident
