Attachment Page 4 of 14 RESPONSE TO ITEMS IN GL 88-01 ITEM 10F NRC GENERIC LETTER 88-01 "Your current plans regarding pipe replacement and/or other measures taken or to be taken to mitigate IGSCC and provide long ters assurance of continued long term piping integrity and reliability."
RESPONSE TO ITEM 1 The focus of the IGSCC mitigation program at Peach Bottom is to replace susceptible piping with resistant material. Other mitigation measures include water chemistry control, inspections and leakage detecticn. No stress improvement is presently planned for piping that has not been replaced. The status of the pipe replacements and water chemistry program are described below. Details concerning the augmented inspection program and leakage detection program are discussed in this response under their applicable NRC Generic Letter 88-01 item numbers.
Status of the P1 ping Replacement Program for NRC Generic Letter 88-01 Scope Piping at PBAPS 2 & 3 The following provides the status of the P8APS piping replacements.
In addition to describing the status of replaced piping, the current status of non-replaced piping is also provided.
The selection of NRC Generic Letter 88-01 IGSCC categories resulted from thoroughly researching currently available documentation containing piping and welding characteristics applicable to IGSCC resistance.
The information necessary to determine IGSCC resistance has been partially indeterminable for a limited number of cases (e.g. delta ferrite, ASTM A262-A testing, etc.).
IGSCC categories for these welds have been selected by comparing characteristics of similar welds of known composition, applying typical or average characteristics to known materials, and performing a metallurgical assessment from experience obtained through the pipe replacement effort. Additionally, changes in IGSCC categories due to future mitigation efforts or availability of additional information will be appropriately reflected in the Peach Bottom ISI program.
Reactor Recirculation System - PBAPS 2:
o The suction and discharge piping in both of the recirculation loops has been replaced with Type 316 controlled chemistry stainless steel. This material has a low carbon content (less than 0.02%) and contains added nitrogen for strength. The piping material meets the requirements specified in General Electric (GE) document E50YP11 for intergranular attack control and was solution heat treated after shop welding. Field welds contain a minimum of 8.0FH and a maximum carbon content of 0.02%. All weldments in this piping are therefore Category A.
The ten recirculation N2 inlet nozzle safe-ends have been replaced with single o
forging Type 316 controlled chemistry stainless steal incorporating a design that eliminates a creviced region. The weld material for the ten N2 nozzle to safe-end welds has been determined to bc ER303L/ER309L with a minimum ferrite reading of 8.0FN. These ten welds are therefore Category A, o
The four safe-end forgings for the RPV N1 nozzles have not been determined to be in conformance with the Staff Position on Materials. One of these welds was inspected by examiners and procedures in conformance with Staff Recomendations
Attachment Page 5 of 14 on Inspection Methods and Personnel and was found to be free of cracks, and is therefore Category D.
The remaining three welds are Category G.
Residual Heat Removal System - P8APS 2:
o The RHR piping described in the scope statement has been replaced with Nuclear Grade Type 316 controlled chemistry stainless steel. This material has a low carbon content (less than 0.02%) and contains added nitrogen for strength.

Attachment Page 8 of 14 ITEM 2 0F NRC GENERIC LETTER 88-01 "An Inservice Inspection (ISI) Program to be implemented at the next refueling outage for austenitic stainless steel piping covered under the scope of this letter that conforms to the staff positions on inspection schedules, methods and personnel, and sample expansion included in this letter."
RESPONSE TO ITEM 2 Augmented ISI Plan for detecting IGSCC The Augmented ISI Plan requirements for the individual Peach Bottom weldments within the scope of this HRC Generic Letter are given as Appendices A and 8 for PBAPS 2 & 3 respectively. These requirements will be integrated with the Inservice Inspection Program to be implehiented at the next refueling outage. The information provided for each weld in the appendices includes the component identification, component description, system identification, and the applicable IGSCC Examination Category according to the requirements of Table 1 of NUREG 0313 Rev. 2.
A weld categorization summary for each unit is provided as Tables 1 & 2 of this response.
NRC Inspection Report 50-277/88-08 and 50-278/88-08 dated April 28, 1988 requested that "... details of proposed subsequent testing of the Unit 2 RHR pipe penetration welds should be included in the response to NRC Generic Letter 88-01 which is due in July 1988." PECo's position is that the RHR piping beyond the inboard isolation valves (M0-18andA0-46A,B)isnotwithinthescopeofthisGenericgettersince the temperature beyond the valves has been determined to be below 200 F during reactor power operation. This position is supported by the lack of any IGSCC indications having been found in the destructive and nondestructive examinations conducted on the Unit 3 penetrations after they were removed for replacement.
Therefore the inspection of the welds in the penetrations is considered to be adequately addressed under the normal ASME Section XI ISI program.
Inspection Schedules l
l The inspections will be performed at frequencies which will be in conformance with i
the Staff Position on Inspection Schedules for the piping welds within the scope of the NRC Generic Letter 88-01. The IGSCC categories for these welds are given in the tables contained in Appendices A and B for PBAPS 2 & 3.
A weld count summary of these tables is provided for PBAPS 2 & 3 in Tables 1 & 2 of this response.
The summary indicates the distribution of welds in each IGSCC Category for the scope systems.
Inspection Methods and Personnel PECo is conrnitted to complying with the NRC Staff positions on inspection methods and personnel as delineated in NRC Generic Letter 88-01. For ultrasonic testing (UT) inspectable ASME Class 1 and 2 welds, the IGSCC inspections will generally be performed in accordance with the requirements contained in the applicable edition and addenda of ASME Section XI for the ASME class of the weldment.
For UT inspectable ASME Class 3 and non-class welds, the requirements in Section XI for Class 2 welds will apply. Details of the volumetric examination method may be upgraded as practical to ensure that the examinations will be effective.
The integrity of ASME Class 1, 2, and 3 welds that are not UT inspectable will be verified by the applicable ASME Section XI pressure test program. The integrity of non-ASME Class welds that are not UT inspectable will be verified by pressure tests in accordance with the requirements of Section XI Article IWB, IWC, or IWD-5000.
Attachment Page 9 of'14 The Reactor Water Clean-up System outside of containment is the only system with significant portions within the scope of the Generic letter that are presently l
considered to be UT uninspectable. The integrity of these welds will be verified by l
the pressure tests of Section XI Article "WB, IWC, or IWD-5000. The Peach Bottom pressure test procedures will be revised to incorporate this portion of the RWCU system.
The edition and addenda of ASME Section XI used for determining these requirements will be as dictated by paragraph (g) of 10CFR50.55a.
The personnel performing the IGSCC volumetric inspections will be qualified for such inspections by a formal program approved by the NRC.
Sample Expansion If one or more Category A, B, or C welds are found to be cracked, or if additional cracks or significant crack growth is discovered in a Category E weld during the interval, a sample expansion plan will be invoked. The sample expansion plan utilized will be as put forth in the Staff Position on Sample Expansion of HRC Generic Letter 88-01.
Categorization Summary The following is a system by system summary resulting from the categorization of these weldments for each unit. This summary is included to facilitate assessment of the Peach Bottom status with regard to IGSCC. Scheduling of the IGSCC examinations for these weldments is as specified in Table 1 of NUREG 0313 Revision 2.
It should be noted that welds which are presently assigned-to Category G will be upgraded to Category D after being UT inspected at the next refueling outage, if they are found to be free of cracking, TABLE 1:

Attachment Page 12 of 14 ITEM 3 0F NRC CENERIC LETTER 88-01 "A change to the Technical Specifications to include a statement on ISI that the Inservice Inspection Program for piping covered by the scope of this letter will be in conformance with the staff positions on schedules, inspection methods and personnel, and sample expansion included in this letter (see enclosed model BWR Standard Technical Specification).
It is recognized that the Inservice Inspection and Testing section may be renoved from the Technical Specifications in the future in line with the Technical Specifications Improvement Programs.
In this case, this requirement shall remain with the ISI section when it is included in an alternative document."
RESPONSE TO ITEM 3 Section 4.6.G of the Peach Bottom Technical Specifications contains surveillance requirements pertaining to the Inservice Inspection Program. The following note will be added to Section 4.6.G:
"The Inservice Inspection (ISI) Program for piping identified in NRC Generic Letter 88-01 shall be perfo med in accordance with the staff positions on schedule, methods and personnel, and sample expansion included in NRC Generic letter 88-01. Details for the implementation of these requirements are included as augmented inspection requirements in the ISI program."
This change will be proposed along with changes to delete some obsolete provisions of Section 3.6 and 4.6 and replace them with applicable portions of the Standard Technical Specifications.
License Amendment applications will be submitted by December 31, 1988.
The ISI program for Peach Bottom is described in the updated FSAR.
In order to implement the IGSCC augmented inspection program in compliance with the terms of NRC Generic Letter 88-01, a revision will be made to the updated FSAR, Appendix I, page I-1, Rev.
3., 01/85, by adding the following:
"The Inservice Inspection (ISI) P.ogram for weldments in piping identified in accordance with the criteria of HRC Generic Letter 88-01 shall be. performed in accordance with the NRC staff positions addressed in this Generic Letter. Details for schedule, methods, personnel, and sample expansion are included as augmented inspection requirements in the 151 program."
Attachment Page 13 of 14 ITEM 4 0F NRC GENERIC LETTER 88-01 "Confirmation of your plans to ensure that the Technical Specification related to leakage detection will be in conformance with the staff position on leak detection included in this letter."
RESPONSE TO ITEM 4 It is Philadelphia Electric's position that the existing Technical Specifications are in conformance with the staff position on leakage detection, and therefore a change to the
' Technical Specifications is not required. A review of the Peach Bottom Technical Specifications 3.6.C and 4.6.C and their associated Bases identified the following:
o The Technical Specifications require that Reactor Coolant unidentified leakage shall be limited to 5 gpm or the unit shall be in hot shutdown within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in cold shutdown within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
o The Technical Specifications require that the rate of change of Reactor Coolant unidentified leakage shall not exceed 2 gpm within a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period or the unit shall be in hot shutdown within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in cold shutdown within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
The Technical Specifications require that total Reactor Coolant System leakage o
be limited to 25 gpm averaged over any 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> surveillance period or the unit shall be in hot shutdown within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in cold shutdcwn within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, o
The Technical Specifications require that the primary containment (drywell) sump collection and flow monitoring system be operable during reactor power operation. From and after the time the system is made or found to be inoperable for any reason, reactor power operation is permissible only during the succeeding 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> unless the system is made operable sooner.
Operability of this system is defined as the ability to measure reactor coolant leakage.
The Technical Specifications require that the Drp ell Atmosphere Radioactivity o
Monitor shall be operable during reactor power operation as a supplement to the reactor coolant leakage monitoring system.
From and after the time the system is made or found to be inoperable for any reason, reactor power operation is permissible for up to 30 days provided grab samples of the containment atmosphere are obtained and analyzed at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
