SUMMARY

OF QUESTIONS AND COMMENTS AUGUST 6,2009, MEETING WITH TENNESSEE VALLEY AUTHORITY WADS BAR NUCLEAR PLANT, UNIT 2 CONSTRUCTION REFURBISHMENT PROGRAM During the meeting presentation by Tennessee Valley Authority (TVA), the Nuclear Regulatory Commission staff asked a number of questions to obtain further clarification of the overall program plan and the method of implementation. In addition, the NRC staff had certain comments regarding some of the details presented. The folloWing is a summary of the questions and comments:

1.

Describe how TVA will be establishing the qualified life for each type of component in its plan.

2.

For Watts Bar Nuclear (WBN) Unit 2, what is the edition (year) used for the code of record of the American Concrete Institute (ACI) Code and American Institute of Steel Construction (AISC) Code?

3.

TVA's Master Equipment List (MEL) does not include all components. Describe the process to update the MEL and reconcile the final MEL prior to system turnover for startup testing. In addition, how will subcomponents inside panels or other devices be addressed?

4.

Spring-can type pipe supports have been considered as passive components. What will the program require for refurbishment of them to ensure that the springs have not been damaged (spring constant changed) due to being in a loaded configuration for a number of years? For example, spring cans locked or pinned since construction.

5.

Describe how masonry-block walls will be addressed in the program.

6.

For each component commodity or attribute listed in Attachment 3 to the program plan, discuss how the specific acceptance criteria will be prOVided to the inspection personnel.

Describe the specific acceptance criteria that will be used for the evaluations.

7.

For instrumentation subcomponents that will not be replaced (e.g., resistance temperature detectors, thermocouple probes, etc.), describe how TVA plans to verify their acceptability. During its review of the program plan, the staff may need to review selected TVA procedures for instrumentation.

8.

Discuss the qualification requirements for Engineering or other field personnel who would be performing the inspections and/or evaluations.

9.

Were any of the safety-related structures at WBN Unit 2 supported by steel piles? If so, how are these piles being inspected or evaluated? Similarly, confirm the methods for inspecting subsurface foundations for structures.

- 2

10.

Describe the source criteria that will be used during the refurbishment of relief valves.

11.

How will be disk to valve seat coefficient of friction be assessed for air-operated valves?

12.

Is a summary of the test data for the concrete in structures available? Summarize the results of the closure report for the Concrete Issues Corrective Action Program Plan.

Describe the monitoring and management of potential corrosion of embedded steel and degradation of concrete. Is the groundwater tested for non-aggressive elements in order to understand how ground-water intrusion impacts concrete and reinforcing steel.

13.

For the WBN Unit 2 equipment that is already in service to support Unit 1, discuss the manner in which TVA will determine that the equipment meets the design and licensing conditions related to the qualified life at Unit 2.

14.

Describe the scope of the pre-service inspection of the containment liner and associated containment penetrations, bellows, and coatings.

15.

Does TVA have a program to monitor the differential settlement of structures at Unit 2?

16.

In reference to the information on page 20 of the plan, state the reasons for not replacing all elastomer or other seals such as ice condenser inlet door seals. What will be done to evaluate these seals?

17.

Describe TVA's plans for oversight and auditing of the implementation of the program and the accomplishment of program objectives.

18.

If there will be procurement of equipment and parts from suppliers not possessing programs and qualifications under Title 10, Code of Federal Regulations, Part 50, Appendix B, how will the commercial grade dedication be accomplished?

19.

What is being done to evaluate the load-carrying requirements for anchor bolts?

20.

Provide the schedule for completion of procedures for refurbishment, inspection, and engineering evaluations under the program plan. The staff will use the schedule and listing to determine if it will audit selected procedures.
