Question: How many personnel do you have in your ISI/IST organization and how are the responsibilities distributed between the ISI/NDE, Risk Informed, Pump and Valve, Containment, System Pressure Test, Snubber, Repair/Replacement Programs, etc.?
Perkins: We have a staff of four program managers (two per unit) that control the ISI/IST activities. ISI Program Managers are responsible for development and implementation of the ISI, RI-ISI, and Containment (IWE/IWL) Programs. IST Program Managers are responsible for development and implementation of IST, Appendix J, and Pressure Test Programs. Snubber testing and examination is covered by the Technical Specification Requirements and controlled by our Maintenance organizations. Repair/Replacement activities are handled by our maintenance and work control organizations in conjunction with procedural requirements that are identified in the ASME Programs Group procedures.
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?
Perkins: We have a number of certified NDE personnel in our Quality Inspections Department that perform routine non-outage inspections (UT, PT, MT, RT, and VT). During outages they provide oversight of the vendors that are brought in to perform the examinations.
Question: What changes have you made in your organizational structure or reporting functions that you have found to be beneficial?
Perkins: None have been made to date. However, a few are under consideration.
Question: What code cases or relief requests have you implemented that have proven to be very helpful and cost effective?
Perkins: The following code cases have been implemented and have been very cost effective due to the decrease in exams required or follow up action required: N-416, N-460, N-491-1, N-509, N-532, N-613, N-566-1, N-524, and N-568.
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?
Perkins: A RI-ISI Program is being developed for Unit 1 and is due to be completed in February 2002. It covers Class 1 and 2 Examination Categories B-F, B-J, C-F-1, and C-F-2 using Code Case N-568 (EPRI methodology) with an estimated cost of less that $200,000. The RI-ISI Program for Unit 2 resulted in a reduction of approximately 65 Class 1 and 2 Code exams. The Program has been approved by the NRC and will be implemented in March 2002. No problems have been encountered in the basic program, however, we submitted a separate RI-ISI Program for welds in the "Break Exclusion Region" as a pilot plant for EPRI. That program is in the NRC review process.
Question: What form of training has proven to be the most successful for your group; in-house instruction, vendor instruction, organizational instruction (EPRI, NSSS, etc.), conferences, technical meetings, online learning, etc.? What ISI/NDE training seminars are you considering for attendance in the near future?
Perkins: I am very fortunate in that I have a very experienced staff that has been involved in ISI/IST activities for several years and they all have been involved in participating in their respective Code meetings and industry forums on a regular basis. My least experienced engineer has approximately 15 years experience. We regularly participate in Code meetings (both OM and ASME Section XI) as well as EPRI sponsored meetings and seminars.
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?
Perkins: We have implemented the requirements of 1995 Edition with the 1996 Addenda of Section XI. We did utilize the recommended EPRI format for relief requests, however, they were modified to suit NRC comments.
Question: What do you find to be the most difficult part of your job?
Perkins: Changing the culture at the station. However, we have added program responsibilities to our scope for AOV's, MOV's, and Check Valve Programs, in addition to the ASME Programs.
Question: What do you find to be the most rewarding part of your job?
Perkins: Developing team relationships at the site with organizations we work with which includes Design, Licensing, Quality Assurance, Quality Inspection-NDE, Maintenance, etc. It is also very rewarding to be involved at the ASME Code meetings and interacting with my counterparts.
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?
Perkins: We have not had any problems with our ISI boundaries. We have had questions relating to how the boundaries were established, but based on our experience we have not had any problems.
Question: Does your organization plan to implement a Section XI edition and/or addenda that is later than currently required in 10 CFR 50, and if so, what benefits do you anticipate?
Perkins: Not at this time.
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?
Perkins: Yes. Examiners are required to identify and size physical obstructions for single side access, etc.. Examiners then map out coverage based on Code requirements, minus the area they can't achieve. Coverage for each weld/area examined is documented in the data sheets.
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?
Perkins: Not at this time. We currently have a full set of our own for each unit.
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?
Perkins: My staffing level doesn't change. We provide support to the Quality Inspection NDE organization to ensure our scope gets completed. Also, our pre-outage scope has decreased due to implementing several Code Cases.
