The following D-RAIs were discussed during the telephone conference call.D-RAI 4.7.2-1Based on the monitoring of the drywell thickness to date, the applicant is requested to providethe following information:(a)For the drywell corrosion existing during the late 1980s, and the new corrosionfound during the subsequent inspections, provide the process used to establish confidence that the sampling done and the areas considered for identifying the areas of corrosion have been adequate.(b)Provide a summary of the factors considered in establishing the minimumrequired drywell thickness at various elevations of the drywell.(c)Reference 4.8-21 cited in the application discusses pros and cons of variousmethods of mitigating the drywell shell corrosion. Provide a summary of the actual mitigating actions taken and their effectiveness.(d)Provide a comparative graph (or chart) showing the drywell thickness based onthe assumed corrosion rate and the actual corrosion rate found after the mitigating actions were implemented.Discussion: Licensee understands the question and will provide a response.D-RAI 4.7.2-2A number of Mark I containments have experienced corrosion inside their drywells at thejunction of the bottom concrete floor and the steel shell. The applicant is requested to provide information regarding corrosion of the drywell shell at this location or any other location of the drywell inside surfaces.Discussion: Licensee understands the question and will provide a response.D-RAI 4.7.2-3Leakage from the refueling seal has been identified as one of the reasons for accumulation ofwater and contamination of the sand-pocket area. The refueling water passes through the gap between the shield concrete and the drywell shell in the long length of inaccessible areas. Asthere is a potential for corrosion in this area, Subsection IWE of the ASME code would require augmented inspection of this area. The applicant is requested to provide a summary of inspections performed (visual and NDE) and mitigating actions taken to prevent water leaks from the refueling seal components.Discussion: Licensee understands the question and will provide a response.D-RAI 4.7.2-4The industry-wide operating experience indicates a number of incidences of torus corrosion inMark I containments. Neither Table 3.5.2.1.1, nor AMP B.1.27, describes operating experiencerelated to corrosion of the Oyster Creek torus. The applicant is requested to provide a summary of the results of IWE inspections performed on the torus, and a description of the torus condition.Discussion: Licensee understands the question and will provide a response.D-RAI 4.7.2-5The staff believes that for this important issue, the updated final safety analysis report (UFSAR)Supplement, should, as a minimum, briefly describe the quantitative aspect of the drywell corrosion, and the applicant's plans to maintain it above a certain thickness to ensure that the containment could perform its intended function during the period of extended operation. Thetime-limited aging analysis (TLAA) and Subsection IWE of the ASME code are the procedures by which the licensee will maintain the containment functionality.Discussion: Licensee understands the question and will provide a response.
