River Bend Station, Unit 1, Request for A dditional Information Regarding Proposed Changes to TS 3.8.4, "DC Sources-Operating" (TAC No. MF0658)
Barry and Joey, by letter dated February 7, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13044A058
), Entergy Operations, Inc. (the licensee) submitted a license amendment request to revise the River Bend Station, Unit No. 1 (RBS) Technical Specification (TS). Specifically, this license amendment request (LAR) proposed to revise TS 3.8.4 Surveillance Requirements (SR) 3.8.4.2 and 3.8.4.5. The changes will add new acceptance criteria to address possible non-conservative conditions when the battery connection resistances are at maximum values. The US Nuclear Regulatory Commission (NRC) staff has determined that the following additional information is required to complete its review of the amendment request. This request was discu ssed with Mr. Barry Burmeister of your staff on December 3, 2013, and it was agreed that a response would be provided within 30 days from the issuance of this email. If circumstances result in the need to revise the requested response date, please contact me at
(301) 415-1445 or via e-mail at Alan.Wang@nrc.gov
.
- 1. On Page 5 of 7 in Attachment 1, the LAR states, "SR 3.8.4.5 specifies that the measured resistance at each inter-cell, inter-rack, inter-tier, and terminal connection will be less than 1.5 E-4 ohms." However, the TS mark-up of the proposed change
in Attachment 2 of the LAR reflects the acceptance criteria of inter-cell, inter-rack, interior, and terminal connection as less than or equal to 1.5 E-4 ohms.
Please clarify the above discrepancy.
- 2. On Page 5 of 7 in Attachment 1, the LAR states, "The surveillance will also be revised to include the additional acceptance criterion that total connection resistance will be less than or equal to 45.75 E-4 ohms." However, Technical Specification Mark-up of the proposed change in Attachment 2 of the LAR reflects the acceptance criteria of total connection resistance as less than 45.75 E-4 ohms.
Please clarify the above discrepancy.
- 3. On Page 1 of 7 in Attachment 1, the LAR, states, "The change will add a total resistance value of 45.75 E-4 ohms to SRs 3.8.4.2 and 3.8.4.5. The current individual connection limit of 1.5 E-4 ohms will remain as unchanged." 10 CFR 50.36 (c)(3) Surveillance Requirement states, "Surveillance requirements are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met."
Please explain how the current TS SR individual connection limits of less than or equal to 1.5 E-4 ohms for inter-cell, inter-rack, inter-tier, terminal connections and the proposed total connection resistance of <45.75 E-4 ohms, in TS SRs 3.8.4.2 and 3.8.4.5, will assure the necessary quality of systems and components. Also, please provide a summary of the calculations including the assumptions and supportive documentation to show that the batteries will perform their intended design functions when operating within these limits.
- 4. On Page 2 of 7 in Attachment 1, the LAR states, "Battery Sizing Requirements: The 2Divisions 1 and 2 batteries have sufficient capacity to power their required safety loads for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> per RBS Calculations E-143 and E-144. The Division 3 battery has sufficient capacity for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> per RBS Calculation G13.18.3.6*09. These calculations include design margin and aging. The batteries are sized in accordance with the methodology of The Institute of Electrical and Electronics Engineers (IEEE) Standard (Std.)
485-1983." IEEE Std. 485-1983 also recommends considering temperature correction factor in cell sizing.
Please, confirm that RBS calculations for battery sizing included appropriate temperature correction factor in addition to the design and aging margins in accordance with IEEE Std. 485-1983.
- 5. Design Requirements on Page 2 of 7 in Attachment 1 of the LAR states, "The minimum acceptable node voltage (i.e., voltage at the terminals of the distribution panels, motor control centers, switchgear, or inverter) shall be greater than 108 VDC at the end of the 4-hour battery duty cycle. This is based on the battery sizing for a final terminal voltage of 110 VDC."
Please, confirm that the voltages (i.e., voltage at the terminals of the equipment downstream of the distribution panels, motor control centers, switchgear, or inverters) shall be greater than or equal to the equipment minimum required voltages at the end of the 4-hour battery duty cycle. In addition, provide a summary of the calculations and assumptions postulated which determines that the limiting component will have the minimum required voltage with the proposed battery connection resistance specified in TS 3.8.4.2 and 3.8.4.5.
