SUBJECT:
TELECOMMUNICATION WITH EXELON GENERATING COMPANY TO CLARIFY THE RESPONSE TO A REQUEST FOR ADDITIONAL INFORMATION PERTAINING TO SECTION 2.3.2 ENGINEERING SAFETY FEATURES SYSTEMS OF THE PEACH BOTTOM LICENSE RENEWAL APPLICATION On August 5, 2002, a conference call was conducted between the Nuclear Regulatory Commission (NRC) staff (hereafter referred to as the staff) and representatives of Exelon Generating Company (hereafter referred to as the applicant) to clarify how environmental qualification (EQ) analysis of the high pressure coolant injection (HPCI) and reactor core isolation cooling (RCIC) pump rooms were conducted for the HPCI/RCIC room cooling coils that are required to maintain the operability of the HPCI/RCIC system during postulated design basis accidents. The staff noticed that the heat transfer function is not identified as the aging effect in Tables 2.3.2-1 and 2.3.2-4 of Section 2.3.2 of the license renewal application for the HPCI pump room cooling coils and the RCIC pump room cooling coils, respectively. The information discussed and the applicants response are provided below. A list of participants of the August 5, 2002, conference call is enclosed.
The applicant referred the above question to a teleconference conducted on December 26, 2001, regarding the staffs request for additional information, 3.2.4.2.1-3, where the staff asked a similar question for RCIC (analogous to HPCI) pump room cooling coils. The applicants response was that the cooling function of the RCIC room cooler is not required for RCIC system operability. The cooling coils are only required to maintain pressure boundary integrity of the emergency service water system. Thus, the applicant clarified that the heat transfer function for the cooling coils was not identified as an intended function. In response to the staffs EQ question, the applicant further clarified that the electrical, instrumentation, and control equipment in the RCIC and HPCI rooms, that needed to be protected against extreme environmental conditions, were relocated outside of the room. Therefore, the applicants EQ analysis of the HPCI/RCIC pump room determined that the HPCI/RCIC pump room cooling coils are not required to maintain the operability of the HPCI/RCIC system for the environmental conditions that were postulated to occur during design basis accidents for the plants.
The staff indicated that the applicants response is adequate and no further action is required.
