Specifically, the licensee proposed to delay the withdrawal of capsule Z of Unit 1 from 2025 to 2027, and to delay the withdrawal of capsule U of Unit 2 from 2027 to 2032. In order to complete its review, the NRC staff requests the following additional information. Please provide your response to the following requests for additional information (RAIs) within 30 days of the date of this correspondence.
2.0 ISSUE In its request, the licensee stated that the proposed withdrawal schedule conforms to ASTM Standard E-185-82, Standard Practice for Conducting Surveillance Tests for Light-Water Cooled Nuclear Power Reactor Vessels, as required by 10 CFR Part 50, Appendix H.
Changes that do not conform to the ASTM standard referenced in Appendix H (ASTM E-185-
- 82) will require approval by the license amendment process.
3.0 RAI
- 1.
Please describe in detail how the proposed capsule withdrawal schedule is in conformance with ASTM E-185-82 requirements for both Unit 1and Unit 2.
- 2.
Based on the submittal for Unit 2, it appears that capsule W has been withdrawn but has not been tested. If the capsule has been tested, please provide the capsule test report, and describe in detail how the status of capsule W affects the conformance of the proposed withdrawal schedule with ASTM E-185-82.
For each request above, please explain the original design and licensing basis requirements and how 10 CFR 50, Appendix H is met for each unit including any voluntary changes that have been incorporated up to ASTM E 185-82.
