Revision to Technical Specification (TS) Table 3.2.B for the Condensate Storage Tank (CST) Low Level Trip Setpoint and Corrections to Typographical Errors Incurred during Prior License Amendment Nos. 223 and 228, dated October 28, 2011 NRC Request for Additional Information (RAI)Attachment 1 "Setpoint Calculation for PS-2390A&B, Condensate Tank Low Level Transfer' of the submitted license amendment request lists the As-Left Tolerance (ALT) value, but does not provide the basis for ALT determination.
The NRC staff notes that the proposed revised setpoint 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, Revision 4, 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 compliance with 10 CFR 50.36 and Regulatory Issue Summary (RIS) 2006-17 by addressing items 2 and 3, below.2. As-Found Setpoint Evaluation:
Describe how surveillance test results and associated TS limits are used to establish operability of the safety system. Show that this evaluation is consistent with the assumptions and results of the setpoint calculation methodology.
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 the instrument being tested are located in a document other than the TS (e.g., plant test procedure) 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 instrument setpoint is, upon completion of surveillance testing, consistent with the assumptions of the 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 RIS 2006-17 are met.Page 1 of 3 ENCLOSURE TO ENTERGY LETTER NO 2.12.035 Enterg¥/Pilqrim Response to NRC Request for Additional Information Dated March 26, 2012 Enterq¥ Response: Response to Item 1: In response to the NRC Request for Additional Information, the Pilgrim technical staff held a conference call with the NRC staff on March 22, 2012 and discussed the setpoint methodology employed for Condensate Storage Tank (CST) water level setpoint calculations.
The methodology follows the guidance of Regulatory Guide 1.105, Rev 3, and is consistent with Regulatory Issue Summary (RIS) 2006-17 and TSTF-493, Rev 4, recognizing that the CST water level setpoint falls within the scope of Limiting Safety System Settings (LSSS) to comply with 10 CFR 50.36. Pilgrim is not adopting TSTF-493, Rev. 4, but follows the guidance as prescribed through RG 1.105, Revision 3 and RIS 2006-17 for applicable instruments specified in 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 previously submitted 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 with Technical Specification (TS) 3/4.2.B, Table 3/4.2.B. Surveillance test results and associated TS limits 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 (Attachment 1), which are consistent with the assumptions and results of the setpoint calculation methodology.
Thus the calibration and surveillance of instruments are in accordance with values 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-left values, 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" to ensure that calculated setpoints that protect safety limits are translated accurately from design documents and associated analysis into calibration procedures.
The process includes the following elements.1. Instrumentation and Control (I&C) Design Engineering personnel prepare the design documents including calculations to determine the setpoint that will ensure that the protective action occurs at the proper value.2. The set point is implemented via an Engineering Change (EC) process, which complies with the applicable requirements of 10 CFR 50, Appendix A and B requirements, and licensing basis information.
- 3. I&C Maintenance personnel incorporate the calculated calibration values into the calibration procedure, as part of the EC process. The procedure 8.M.2-2.5.6 makes reference to the Technical Specification Value included in TS Table 3/4.2.B, and provides for the following:
Page 2 of 3 ENCLOSURE TO ENTERGY LETTER NO 2.12.035 Entergy/PilIrim Response to NRC Request for Additional Information Dated March 26, 2012* Acceptance Criteria, based on controlled engineering documents* Corrective Action* Acceptance Verification
- I&C Procedure Feedback Form 4. 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 no adjust limits. Condition Reports (CR) are coded for drift evaluation and trending.
I&C System Engineers are assigned corrective actions to evaluate the drift of critical components to determine if the instrument has been having repeat issues.Pilgrim follows Entergy fleet procedure, EN-LI-102, "Corrective Action Process" to implement the site corrective action program. This process complies with the requirements of 10 CFR 50, Appendix B. Equipment and instrument operability, restoring operability, accepting degraded conditions with compensatory measures, and operability evaluations are developed in accordance with Entergy Fleet procedure, EN-OP-104, "Operability Determination Process." Corrective Actions taken to restore operability follow the process prescribed in EN-LI-102.

[1] Impact on Operations NOTE Close signal to MO-2301-6 is generated from MO-2301-35 and MO-2301-36 being full open. MO-2301-35 and MO-2301-36 being full open will also generate a close signal to HPCI/RCIC Test Return Valve MO-2301-15 and Full Flow Test Valve MO-2301-10.(a) Surveillance Summary This Procedure tests the Condensate Storage Tank (CST) low level logic by simulating a low level condition which provides an open signal to Torus Suction Valves MO-2301-35 and MO-2301-36 and a close signal to CST Suction Valve MO-2301-6 if an auto-isolation signal is not present.Attachment 1 performs a functional test of pressure switches 23-PS-2390A and 23-PS-2390B.
Attachment 2 performs a functional and calibration of pressure switches 23-PS-2390A and 23-PS-2390B.(b) Impact HPCI will be available during performance of Attachments 1 and 2 as no loss of suction path occurs, but Condensate Storage Tank low level instrumentation will be less than the minimum number of operable channels during calibration.
Therefore, HPCI is inoperable (Technical Specifications 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 Procedure monitor the water levels in the Condensate Storage Tank. Upon sensing a low Condensate Storage Tank water level, these switches provide control logic signals which automatically close MO-2301-6 and open MO-2301-35 and MO-2301-36 to supply water to the HPCI pump suction if the HPCI isolation signal is not activated.
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 with Technical Specifications Sections 3.2.B and 4.2.B.8.M.2-2.5.6 Rev. 35 Page 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
