Goulart:ISI, Risk informed, IWE Containment(contact Jeff Goulart 423 843-6846)

IST, Pump and Valve(contact Larry Alexander 423 843-7495)

Containment Appendix J(contact Frank Bodine 423 843-6940)

Repair/replacement & Pressure Testing(contact Ken Wilson 423 843-7026)

Question:How much of the NDE is actually performed by your organization, if any, in lieu of utilizing outside vender support, and if so, what savings have you recognized by using your in-house personnel?

Goulart:Non outage all NDE in house;Outage 90% outside vendor.(contact Joel Whitaker 423 843-7355)

Question:What changes have you made in your organizational structure or reporting functions that you have found to be beneficial?

Goulart:Having all the programs in one group.

Question:What issues proved to be very difficult, costly, or troublesome to resolve, and what would you recommend to avoid those issues in the future?

Goulart:RI-ISI program and updates.

Question:What code cases or relief requests have you implemented that have proven to be very helpful and cost effective?

Goulart:Code cases N-490 and N-509 these were implemented in the second interval.

Question:Has your organization implemented a risk informed ISI or IST program, and if so, what Code Cases or methodology did you incorporate and what benefits and savings have you realized?What was the scope of the program and the approximate costs to develop the program?Were there any unexpected problems encountered while developing the program?Did you receive any requests for additional information from the NRC and has your program been approved?

Goulart:RI-ISI implemented on the Class 1 and 2 BF, BJ and CF welds.Westinghouse method used.Benefit reduced weld examination population.Scope Class 1 and 2.Estimated cost for three units 1.5 million.Major problem the amount of time to prepare the initial program and the updates.The second interval was approved and received RAIís.The third interval request has been submitted to NRC for approval.


RI-IST has not been attempted.

Question:What new NDE techniques, technology, or special NDE situations have you encountered recently and were they successful?

Goulart:Pulsed eddy current for corrosion mapping of feedwater heaters.

Automated UT of reactor coolant pump shafts.

Acoustic emissions of lifting devices.

(contact Joel Whitaker 423 843-7355)

Question:Has your organization implemented the requirements for ASME Section XI, Appendix VIII, of the 1995 Edition with the 1996 Addenda?Did you utilize the recommended EPRI format for relief requests, and if so, which ones?What is the approval status of your relief requests and what problems or successes have you encountered in implementing Appendix VIII?

Question:What do you find to be the most difficult part of your job?

Goulart:Implementing and maintaining the RI-ISIpart.

Question:Have you had any difficulties or questions regarding the code classification of system components or establishing the code classification boundaries?If so, what difficulties or questions did you encounter and how did you resolve the issues?What technical positions did you take?

Goulart:At the start of the Second Interval, we reconciled our design basis with RG 1.26 and developed a design calculation to document the code classifications.From this we developed our color coded boundary drawings used for our ASME Code programs.The boundary drawings are design output drawings which we maintain through our design change process.This has been a great help since the basis for each system and all the boundaries are documented.(contact Ken Wilson 423 843-7026)

Question:Have you had any difficulties or questions applying the Section XI Repair/Replacement Rules to components, spare parts, etc., and if so, what difficulties or questions did you encounter and how did you resolve the issues?What technical positions did you take?

Goulart:The only problems encountered have been in house with planners and procurement personnel who do not understand Code requirements as well as one would like.(contact Ken Wilson 423 843-7026)

Goulart:Not at this time, but would if it would be beneficial.

Question:Do your NDE procedures include a methodology for calculating the examination coverage for limited examinations, and if so, how is this calculation performed and what considerations are included?

Goulart:Yes, procedure is complex (contact Joel Whitaker 423 843-7355)

Question:Does your plant share any calibration blocks on a regular basis with other plants outside of your organization, and if so, what types of blocks do you share and who do you share them with?

Goulart:Blocks are shared within TVA sites (contact Joel Whitaker 423 843-7355)

Question:As outages become shorter and shorter, how are you able to handle your ISI workload during the outage?Are you supplementing your staff with additional temporary personnel or are some tasks getting deferred?

Goulart:Accountability has not been lost.Procedures or data bases are used to track examinations.

Question:What type of software do you use to track and analyze ISI program commitments and inspection data?Was the software developed by your organization or purchased from a vender?Does it adequately meet your needs?If not, why not?
