performance, and chemical compatibility of the reactivity control elements. 4. Section 5.2.3: review of control rod drive system portions that are part of the reactor coolant pressure boundary (RCPB); verification of whether materials of construction and fabrication controls satisfy criteria for RCPB materials. 5. Section 5.3.1: review of control rod drive portions that are reactor vessel attachments or appurtenances; verification of whether materials of construction and related fabrication controls satisfy the criteria for reactor vessel materials. 6. Sections 5.4.8, "Reactor Water Cleanup System (BWR)," and 9.3.4, "Chemical and Volume Control System (PWR)”: review of the acceptability of the reactor coolant chemistry and chemistry controls (including such additives as inhibitors) as to corrosion control and compatibility with control rod drive structural materials. 7. Section 12.1: review of the plant design, including selection of materials to minimize activation products, for whether occupational radiation exposures will be as low as is reasonably achievable. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. GDC 1, as it relates to SSCs important to safety being designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. 2. GDC 14, as it relates to the RCPB being designed, fabricated, erected, and tested to have an extremely low probability of abnormal leakage, rapidly propagating failure, or gross rupture. 4.5.1-4 Revision 3 - March 2007 3. GDC 26, as it relates to control rods being capable of reliable control of reactivity changes to assure that under conditions of normal operation, including anticipated operational occurrences, and with appropriate margin of malfunctions, specified
