Content:
d sensing and actuation instrumentation of the plant protection system, located both inside and outside the reactor containment. The Chemical Engi- neering Branch (CMEB), as part of its primary review responsibility for SRP Section 6.1.1, will generically evaluate the corrosion rates of materials (such as galvanized steel and aluminum) exposed to containment spray solutions. The CMEB, as part of its primary review responsibility for SRP Section 6.1.2, will evaluate the hydrogen generation rates from the radiation decomposition of organic materials (such as primers/coatings and cable insulation), and the corro- sion rates of materials (such as zinc-based primers) exposed to containment spray solutions. CSB will request CMEB participation in the evaluation of analyses of hydrogen generation from the radiolysis of reactor coolant and sump water when such analyses by applicants do not follow the guidance of Appendix A to this SRP section. The Radiological Assessment Branch (RAB), as part of its primary review responsibility for SRP Section 12.3, will evaluate the accessi- bility of combustible gas control systems equipment under postulated accident conditions. The Licensing Guidance Branch (LGB), as part of its primary review responsibility for SRP Section 16.0, will review, at the operating license stage of review, proposed technical specifications pertaining to the operability and leakage rate testing of systems and components. For those areas of review identified above as being reviewed 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 CSB acceptance criteria for the design of the systems provided for combustible gas control are the relevant requirements of 10 CFR Part 50, §§ 50.44 and 50.46 and General Design Criteria 5, 41, 42 and 43. The requirements are as
