Typo
- Rob, No need to discuss on the phone but specific to this DRAI, we believe there is a typo. The UFSAR section should be 3.8.4.6.2.1 versus what I highlighted below DRAI 3.5.2.1.1-1
Background
LRA Table 3.5.1, item 3.5.1-68 addresses high-strength structural bolting and states that it is not applicable because high strength structural bolts subject to SCC are not used in this application. The GALL Report recommends GALL Report AMP XI.S3, ASME Section XI, Subsection IWF to manage cracking due to stress corrosion cracking for this component group.
Issue The staff lacks sufficient information to evaluate the applicants claim because a review of UFSAR Sections 3.8.3.1.2, Reactor Pedestal, 3.8.6.2.1, Structural Steel Materials, and 3A.7.1.2.2.1, Downcomer Bracing System, state that high strength structural steel bolting is used. It is reasonable to assume that at least some of the referenced UFSAR sections are describing components that contain bolting within the scope of license renewal. The staff reviewed the LRA and did not find any other means by which SCC would be managed for high strength structural bolting.
