RAI request for LAR-17-030 (Vogtle Units 3 and 4) 1-8-2018 Additional Information Requested
- 1. Please explain whether test participants who will form the crews for ISV retesting will also meet the selection criteria in APP-OCS-GEH-320, Section 4.1.1.
2 Please explain the specific changes that will be made to the ISV scenarios that meet the requirements for ISV retesting in APP-OCS-GEH-320, Section 7.3, and explain what, if any, impact the changes will have on the ability to draw conclusions that the changes implemented to address HEDs are effective.
3 Please explain why scenarios used for retesting will meet the criteria in NUREG-0711, Section 8.4.6.2 for performance-based testing instead of the criteria in NUREG-0711, Section 11.4.3 for validation testing.
- 4. Please explain whether APP-OCS-GEH-320, Section 6.3.1 needs to be revised to align with Section 7.3. If so, please revise APP-OCS-GEH-320, Section 6.3.1.
- 5. Please identify the specific scenarios that require retesting in accordance with APP-OCS- GEH-320, and the changes that have been implemented to resolve the significant HEDs identified in these scenarios.
- 6. Please explain how reducing the required number of successful retest results needed to determine the design is validated provides a logical basis for determining the design supports safe plant operation.
