Turkey Point EPU - Containment and Ventilation (SCVB) Request for Additional Information -
Round 1.2 (Part 2)Tom, Below are requests for additional information (RAIs) regarding the Turkey Point Extended Power Uprate (EPU) license amendment request. On March 31, 2011, the Nuclear Regulatory Commission (NRC) staff and Florida Power & Light Company (FPL) held a public meeting to discuss draft RAIs generated from various NRC technical branches while reviewing the October 21, 2010, EPU application. During the public meeting, it was concluded that draft questions SCVB-1.11 and SCVB-1.12 regarding containment accident pressure and Generic Letter 2004-02 would be withdrawn and revised. Below are the revised SCVB questions that take the place of questions SCVB-1.11 and SCVB-1.12. These questions are categorized as Part 2 questions since they are not follow-up or Round 2 questions to the previous SCVB questions issued (Agencywide Documents Access and Management System Accession No. ML110950084). On April 28, 2011, you stated that a call is not needed to discuss the draft RAIs sent to you via email. The below RAIs reflect the questions that were
sent to you and agreed upon by FPL. FPL agreed upon provid ing its responses within 30 days of the date of this email. If you have any questions, feel free to contact me.
SCVB-1.2.1 Provide the basis for the NPSH required (NPSHR) of the residual heat removal (RHR) and containment spray (CS) pumps (tested value, extrapolation to flows other than tested flows),
including flow rates assumed, and a comparison with the flow rate for the LOCA peak cladding temperature (PCT analyses). What head drop value is used for NPSHR (3% head drop or other)?
SCVB-1.2.2 Provide details of the method of calculating NPSH available (NPSHA) for the RHR and CS pumps (e.g. RWST level, containment atmospheric pressure, vapor pressure, head loss through suction piping, sump water temperature). Also, clarify the statement in licensing report (LR) Section 2.6.5.2.2 that "NPSH evaluations for the recirculation phase assume 212°F sump temperature and 0 psig containment pressure." Specifically, is the statement intended to convey that containment atmospheric pressure and the vapor pressure terms in NPSHA are assumed to nullify each other, thus resulting in no credit for CAP?
SCVB-1.2.3 Provide calculated NPSH margins for the RHR and CS pumps at the EPU conditions for however long a duration the calculations were performed during design basis accidents. Describe the lineup of the pumps and provide the results in a tabular form, clearly indicating
NPSHA and NPSHR for each pump.
SCVB-1.2.4 Demonstrate that NPSH margin still exists after including the uncertainties in the required NPSH, without crediting CAP. The NRC staff, in consultation with a pump expert, determined that a 21-percent margin on the '3%-required NPSH' would conservatively envelope the uncertainties discussed in the draft guidance document. It is acceptable to the NRC staff, if desired, to use this value in lieu of performing detailed plant specific uncertainty evaluation.
SCVB-1.2.5 It was stated in LR Section 2.6.5.2.5 of the EPU that during recirculation phase, adequate NPSH margin is available if only one RHR pump and one CS pump are operated simultaneously. Provide additional details on this lineup, how it differs from other lineups, and the reasons why NPSH margin is impacted.
2SCVB-1.2.6 Provide a discussion of how the post accident debris generation at Turkey Point is impacted by the EPU and the resultant impact on the sump strainer head loss and on the RHR pump NPSH
