POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 LICENSE RENEWAL APPLICATION January 10, 2005 The U.S. Nuclear Regulatory Commission staff (the staff) and representatives of Nuclear Management Company, LLC (NMC) held a telephone conference call on January 10, 2005, to discuss and clarify the staffs requests for additional information (RAIs) concerning the Point Beach Nuclear Plant, Units 1 and 2, license renewal application (LRA). The following RAIs were discussed during the telephone conference call.
Section 2.3.4 Steam and Power Conversion Systems 2.3.4.2 Feedwater and Condensate System Request for Additional Information (RAI)
RAI 2.3.4.2-4 In a letter dated November 16, 2004, the Nuclear Regulatory Commission'(NRC) requested additional information regarding the Auxiliary Systems (LRA Section 2.3.3) and Steam and other Balance of Plant (BOP) Systems in LRA Sections 2.3.3 and 2.3.4 respectively. PBNP response to this request was submitted to the NRC in Nuclear Management Company, LLC letter dated December 22, 2004. The NRC review of the PBNP response to RAI 2.3.4.2-1 identified two follow-up questions regarding the scoping for the small bore branch piping from the NSR portion of the 16" main feed water header (FW) between the feed regulating valve and the downstream steam generator FW inlet check valve:
1.
Recognizing the NRC would not require a formal HELB evaluation be preformed on piping 1-inch and less, did PBNP perform any evaluation (i.e., walkdown, etc.) to confirm that a break in the branch piping would not impact any safety related equipment in the immediate vicinity of the possible break location?
2.
Please discuss flooding associated with a failure in the branch piping and its impact on safety related equipment.
Discussion: The applicant clarified their draft response. The applicant will provide their formal response in writing.
ENCLOSURE RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION REGARDING POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 LICENSE RENEWAL APPLICATION (LRA)
The following information is provided in response to the Nuclear Regulatory Commission (NRC) staff's request for additional information (RAI) regarding the Point Beach Nuclear Plant (PBNP)
The NRC staff's question is restated below, with the Nuclear Management Company (NMC) response following.
Section 2.3.4 Steam and Power Conversion Systems 2.3.4.2 Feedwater and Condensate System Request for Additional Information (RAI)
RAI 2.3.4.2-4 In a letter dated November 16, 2004, the Nuclear Regulatory Commission'(NRC) requested additional information regarding the Auxiliary Systems (LRA Section 2.3.3) and Steam and other Balance of Plant (BOP) Systems in LRA Sections 2.3.3 and 2.3.4 respectively. PBNP response to this request was submitted to the NRC in Nuclear Management Company, LLC letter dated December 22, 2004. The NRC review of the PBNP response to RAI 2.3.4.2-1 identified two follow-up questions regarding the scoping for the small bore branch piping from the NSR portion of the 16" main feed water header (FW) between the feed regulating valve and the downstream steam generator FW inlet check valve:

2.
Please discuss flooding associated with a failure in the branch piping and its impact on safety related equipment.
NMC Response:
- 1)
The section of main feedwater piping in question, was included in scope to protect the safety-related (but non-EQ) feedwater flow transmitters (1/2FT-466, -467, -476, -477).
Walkdowns were originally performed to verify that no high energy piping (including branch piping 1 and under) was in proximity to the SR transmitters where pipe whip or jet impingement could be a hazard. Additionally, the transmitters are in large open areas where the energy input from a failure of a small bore line off of this header would not be able to create a harsh environment for these transmitters.
- 2)
The SR feedwater flow transmitters are located on the 26 elevation for U2 and the 39 elevation for U1, and mounted about 4 feet off of the floor. Any leakage from the main feedwater header branch connections at these elevations would cascade to lower elevations, and would not create any potential for flooding to impact the function of these transmitters nor any other safety-related equipment.
