NRC Letter, Request for Additional Information -Pilgrim Nuclear Power Station RE:Revision to Condensate Storage Tank Low Level Setpoint, dated March 26, 20122. Entergy Letter No. 2.11.040, Proposed License Amendment: Revision to TechnicalSpecification (TS) Table 3.2.B for the Condensate Storage Tank (CST) Low Level TripSetpoint and Corrections to Typographical Errors Incurred during Prior LicenseAmendment Nos. 223 and 228, dated October 28, 2011NRC Request for Additional Information (RAI)Attachment 1 "Setpoint Calculation for PS-2390A&B, Condensate Tank Low Level Transfer' ofthe submitted license amendment request lists the As-Left Tolerance (ALT) value, but does notprovide the basis for ALT determination. The NRC staff notes that the proposed revisedsetpoint is one of the Limiting Safety System Settings (LSSS) listed for the NUREG-1433,Boiling Water Reactor/4 Plants in the Technical Specification Task Force (TSTF)-493, Revision4, which is described in Federal Register Notice, Notice of Availability of the Models for Plant-Specific Adoption of Technical Specifications Task Force Traveler TSTF-493, Revision 4,"Clarify Application of Setpoint Methodology for LSSS Functions," Vol. 75, No. 90 / Tuesday,May 11,2010 (75 FR 26294).1. Describe whether and how you plan to apply the TSTF-493, Revision 4 for this setpoint.If you do not plan to adopt the TSTF-493, then explain how you will ensure compliancewith 10 CFR 50.36 and Regulatory Issue Summary (RIS) 2006-17 by addressing items 2and 3, below.2. As-Found Setpoint Evaluation: Describe how surveillance test results and associatedTS limits are used to establish operability of the safety system. Show that thisevaluation is consistent with the assumptions and results of the setpoint calculationmethodology. Discuss the plant corrective action processes (including plant procedures)for restoring channels to operable status when channels are determined to be"inoperable" or "operable but degraded." If the criteria for determining operability of theinstrument being tested are located in a document other than the TS (e.g., plant testprocedure) explain how the requirements of 10 CFR 50.36 and RIS 2006-17 are met.3. As-Left Setpoint Control: Describe the controls employed to ensure that the instrumentsetpoint is, upon completion of surveillance testing, consistent with the assumptions ofthe associated analyses. If the controls are located in a document other than the TS(e.g., plant test procedure) explain how the requirements of 10 CFR 50.36 and RIS2006-17 are met.Page 1 of 3 ENCLOSURE TO ENTERGY LETTER NO 2.12.035Enterg¥/Pilqrim Response to NRC Request for Additional InformationDated March 26, 2012Enterq¥ Response:Response to Item 1:In response to the NRC Request for Additional Information, the Pilgrim technical staff held aconference call with the NRC staff on March 22, 2012 and discussed the setpoint methodologyemployed for Condensate Storage Tank (CST) water level setpoint calculations. Themethodology follows the guidance of Regulatory Guide 1.105, Rev 3, and is consistent withRegulatory Issue Summary (RIS) 2006-17 and TSTF-493, Rev 4, recognizing that the CSTwater level setpoint falls within the scope of Limiting Safety System Settings (LSSS) to complywith 10 CFR 50.36. Pilgrim is not adopting TSTF-493, Rev. 4, but follows the guidance asprescribed through RG 1.105, Revision 3 and RIS 2006-17 for applicable instruments specifiedin TSTF-493, Rev 4, within the scope of the proposed License Amendment.Attachment 1 provides Calculation No. IN1-245, "Setpoint Calculation for PS-2390A & B,Condensate Tank Low Level Transfer" dated October 7, 2009. This calculation was previouslysubmitted in our initial License Amendment submittal (Reference 2).Response to Items 2 and 3:Attachment 2, Pilgrim Procedure No. 8.M.2-2.5.6, "HPCI Condensate Storage Tank Level",Revision 35, provides details of setpoint calibration and surveillance in compliance withTechnical Specification (TS) 3/4.2.B, Table 3/4.2.B. Surveillance test results and associated TSlimits are used to establish operability of the safety system. The as-found and as-left values (no-adjust limits) are based upon limits established in the setpoint calculation INI1-245 (Attachment1), which are consistent with the assumptions and results of the setpoint calculationmethodology. Thus the calibration and surveillance of instruments are in accordance withvalues derived through the setpoint methodology and will ensure safety system operability,thereby demonstrating compliance with 10 CFR 50.36.Procedure 8.M.2-2.5.6 controls the setpoints, addresses setpoint drift, as-found and as-leftvalues, and surveillance practices for instruments that are required to protect LSSS safety limits.The Pilgrim staff follows Entergy fleet procedure EN-DC-1 15, "Engineering Change Process" toensure that calculated setpoints that protect safety limits are translated accurately from designdocuments and associated analysis into calibration procedures. The process includes thefollowing elements.1. Instrumentation and Control (I&C) Design Engineering personnel prepare the designdocuments including calculations to determine the setpoint that will ensure that theprotective action occurs at the proper value.2. The set point is implemented via an Engineering Change (EC) process, which complies withthe applicable requirements of 10 CFR 50, Appendix A and B requirements, and licensingbasis information.3. I&C Maintenance personnel incorporate the calculated calibration values into the calibrationprocedure, as part of the EC process. The procedure 8.M.2-2.5.6 makes reference to theTechnical Specification Value included in TS Table 3/4.2.B, and provides for the following:Page 2 of 3 ENCLOSURE TO ENTERGY LETTER NO 2.12.035Entergy/PilIrim Response to NRC Request for Additional InformationDated March 26, 2012* Acceptance Criteria, based on controlled engineering documents* Corrective Action* Acceptance Verification* I&C Procedure Feedback Form4. A condition report (CR) will be written in accordance with Entergy procedure, EN-LI-102,"Corrective Action Process", if the technician finds the as-found value is outside the noadjust limits. Condition Reports (CR) are coded for drift evaluation and trending. I&CSystem Engineers are assigned corrective actions to evaluate the drift of criticalcomponents to determine if the instrument has been having repeat issues.Pilgrim follows Entergy fleet procedure, EN-LI-102, "Corrective Action Process" to implementthe site corrective action program. This process complies with the requirements of 10 CFR 50,Appendix B. Equipment and instrument operability, restoring operability, accepting degradedconditions with compensatory measures, and operability evaluations are developed inaccordance with Entergy Fleet procedure, EN-OP-104, "Operability Determination Process."Corrective Actions taken to restore operability follow the process prescribed in EN-LI-102.Attachment 3 provides revised TS Page 3/4.2-16, which provides foot notes to the CondensateStorage Tank Low level Set point.

MO-2301-35 and MO-2301-36 being full open will also generate a close signalto HPCI/RCIC Test Return Valve MO-2301-15 and Full Flow Test Valve MO-2301-10.(a) Surveillance SummaryThis Procedure tests the Condensate Storage Tank (CST) low level logicby simulating a low level condition which provides an open signal toTorus Suction Valves MO-2301-35 and MO-2301-36 and a close signal to CSTSuction Valve MO-2301-6 if an auto-isolation signal is not present.Attachment 1 performs a functional test of pressure switches 23-PS-2390Aand 23-PS-2390B. Attachment 2 performs a functional and calibration ofpressure switches 23-PS-2390A and 23-PS-2390B.(b) ImpactHPCI will be available during performance of Attachments 1 and 2 as noloss of suction path occurs, but Condensate Storage Tank low levelinstrumentation will be less than the minimum number of operablechannels during calibration. Therefore, HPCI is inoperable (TechnicalSpecifications Table 3.2.B Note 1).(c) Technical Specifications(1) Section 3.5.C(2) Tables 3.2.B/4.2.B[2] The pressure switches (23-PS-2390A, 23-PS-2390B) tested by this Proceduremonitor the water levels in the Condensate Storage Tank. Upon sensing a lowCondensate Storage Tank water level, these switches provide control logicsignals which automatically close MO-2301-6 and open MO-2301-35 and MO-2301-36to supply water to the HPCI pump suction if the HPCI isolation signal is notactivated.The following components are affected by this Procedure:(a) MO-2301-6 (CST SUCT VLV)(b) MO-2301-35 (TORUS SUCT VLV)(c) MO-2301-36 (TORUS SUCT VLV)[3] The instrument functional/calibration test shall be done in accordance withTechnical Specifications Sections 3.2.B and 4.2.B.8.M.2-2.5.6 Rev. 35Page 6 of 33 5.0 SPECIAL TOOLS AND EQUIPMENT[1] Pneumatic calibrator/test gauge accurate to 0.03 psig or better[2] Portable communication equipment[3] Digital multimeter (DMM) or equivalent[4] Calibrated chart recorder or digital timer (required for relay 23A-K15calibration only)[5] Torquing screwdriver capable of 11 inch-pounds[6] 1/2" female Swagelok fitting6.0 PRECAUTIONS AND LIMITATIONS6.1 PRECAUTIONS[1] One pressure switch shall be tested or disabled at a time unless otherwisedirected by this Procedure.[2] Unless otherwise directed, the pressure switches under test shall beindividually isolated in accordance with the applicable Attachment providedfor the pressure switch under test.[3] All applicable plant radiological precautions shall be observed during theperformance of this Procedure to reduce exposure to radiation and spread ofcontamination.(a) Use an appropriate catch-container and absorbent material whenconnecting and removing test equipment.[4] Use caution while working on energized circuits to protect personnel andprevent damage to plant equipment.[5] Personnel must be informed of the Halon fire protection system in the CableSpreading Room.
