September 20, 2002 LICENSEE :
Exelon Corporation FACILITIES:
Peach Bottom, Units 2 and 3
SUBJECT:
TELECOMMUNICATIONS WITH EXELON CORPORATION TO DISCUSS RESPONSES TO A REQUEST FOR ADDITIONAL INFORMATION PERTAINING TO SECTIONS B1, B2, AND 2.4.16 OF THE PEACH BOTTOM, UNITS 2 AND 3, LICENSE RENEWAL APPLICATION On March 6, 2002, the NRC staff (hereafter referred to as the staff) issued a request for additional information (RAI) pertaining to aging management activities of the license renewal application (LRA). Exelon Corporation (hereafter referred to as the applicant) responded to this request by letter, dated May 14, 2002. The staff needed clarification to the applicants responses on LRA Sections B1, B2, and 2.4.16. On August 6 and 8, 2002, conference calls were conducted between the staff and the applicant. A list of participants of the conference calls are provided in Enclosures 1 and 2.
On August 6, 2002, the staff requested the applicant expand upon their RAI response for LRA Section B.1.3 in two areas of the LRA. Section B.1.3 pertains to the closed cooling water chemistry program. The staff requested clarification on planned monitoring and inspection activities. The applicant responded that the monitoring and inspection activity is part of an existing program, rather than a planned program, based on water chemistry guidance contained in EPRI Report 107396. The staff also requested specific concentrations for the acceptance criteria parameters, including chloride and sulfate. The applicant responded that the acceptance criteria is below 10 parts per million for both chloride and fluoride and, typically, measurements are below 1 part per million. There is no limit for sulfate and the data trend is monitored.
The second RAI, regarding LRA Section B.2.12, pertains to the heat exchanger inspection activities. The staff requested clarification on the applicants response for the inspection procedures used to determine acceptability of the heat exchanger tubes. The applicant responded that the high pressure coolant injector (HPCI) gland seal condenser, HPCI turbine lube oil cooler, and reactor cone isolation cooling (RCIC) lube oil cooler are very small heat exchangers; all tubes are fully disassembled, thoroughly cleaned, and visually inspected. No boroscope is used in the procedure. The inspection procedures were included in a subsequent e-mail, which is provided in Enclosure 3.
On August 8, 2002, the staff requested clarification on LRA Section 2.4.16 to determine if supports for cable trays and conduits are within the scope of the license renewal. The applicant responded that the relevant information is contained in LRA Section 2.4.13 on the support system.
Regarding Section B.2.5, the staff asked the applicant to explain the frequency of inspections.
The applicant responded that emergency cooling water (ECW) pumps are inspected every 10 years and the refueling water storage tanks (RWST) are inspected every 4 years. The staff also asked about LRA Section B.3.4, as to when the one-time inspection of piping would be performed. The applicant responded that the inspection would occur before the end of the plant life, between years 30 and 40.
The staff finds that three items may potentially become confirmatory items in the safety evaluation report for the Peach Bottom Atomic Power Station LRA: 1) numerical limits and actual measurements of the water chemistry; 2) inspection of HPCI gland seal condenser, HPCI turbine lube oil cooler, and RCIC lube oil cooler heat exchanger tubes; and 3) frequency of inspections of the ECW pumps and RWST. If any of these items become confirmatory, the applicant will need to submit a written response to confirm this information.
A draft of this telecommunication summary was provided to the applicant to allow them the opportunity to comment prior to the summary being issued. The applicant provided comments to specify the heat exchangers discussed in Section B2.12.

RE: Request for telecon regarding Peach Bottom license review
- Jerry, The following procedures are all that are applicable to the heat Exchanger Inspection Activity:
PMT 251038 PMT 251499 M-C-750-003 PMT 324804 PMT 377840 M-C-756-006 Our approach is to disassemble and inspect for degradation, and if there is no degradation then there is no flow blockage and no loss of heat transfer.
Note that this is an acceptable approach under the rules of GL 89-13.

RE: Request for telecon regarding Peach Bottom license review Mr. Philliabaum:
As we discussed on the phone, we plan to call you and your technical expert at 10am Tuesday 8/6.
Here are the questions that we will discuss:
B.1.3 Closed Cooling Water Chemistry Program For the monitoring and trending parameter, have you committed to a date/schedule to begin the monitoring and inspection activities for the closed cooling water chemistry AMP? If so, what is your planned date to begin this activity?
For the acceptance criteria parameter, you indicated the specific levels for concentration of the ph, nitrite, and TTA. Do you have specific quantitative levels for the chlorides, sultates, etc? If so, pls. provide those levels.
B.2.12 Heat Exchanger Inspection Activities For the program scope parameter, please indicate the number of tubes inspected or percentage of tubes inspected.
For the detection of aging effects parameter, how are you visually inspecting the tubes; are you using a borescope? If not, is NDE being applied-how do you verify what is going on in the tubes?
For the acceptance criteria parameter, what are the acceptance criteria for the tubine operability surviellance test? Address % flow blockage that is not acceptable, % loss of heat transfer not acceptable or level of operability.
If you have any questions, please call me at 301-415-3407.
