SUBJECT:
WATERFORD STEAM ELECTRIC STATION. UNIT 3 - CORRECTION TO AMENDMENT NO. 233 RE: TECHNICAL SPECIFICATION TABLE 3.4-1 ISOLATION VALVE ADDITION (TAC NO. ME3421)
Dear Sir or Madam:
By letter dated March 23, 2011 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML110630259), the U.S. Nuclear Regulatory Commission (NRC) issued Amendment No. 233 to Facility Operating License No. NPF-38 for the Waterford Steam Electric Station. Unit 3. This amendment consisted of changes to the Technical Specifications (TSs) in response to Entergy Operations, Inc.'s (Entergy's, the licensee's) application dated February 22, 2010, as supplemented by letters dated June 8 and August 12. 2010, and January 4 and March 7, and March 18,2011.
The amendment added valve SI-4052A (Reactor Coolant Loop (RCL) 2 Shutdown Cooling (SDC) suction inside containment bypass isolation) and valve SI-4052B (RCL 1 SDC suction inside containment bypass isolation) to TS Table 3.4-1, "Reactor Coolant System Pressure Isolation Valves." This bypass line equalizes the SDC system pressure downstream of valve SI-405A(B) (RCL 2(1) SDC suction inside containment isolation) in order to minimize the pressure transient In the system when valves SI-405A(B) are opened.
The NRC staff has now noticed that Entergy's letter dated March 18, 2011, was not identified as a supplement in the NRC's letter dated March 23, 2011. The NRC staff has corrected the transmittal letter, page 1 of the amendment letter, pages 1 and 8 of the SE, and the Notice of Issuance referencing the March 18, 2011 letter (ADAMS Accession No. ML11115A159). The location of the correction is identified by the revision bar on the right. The corrected documents are enclosed.
The Commission has forwarded the corrected Notice of Issuance of Amendment to Facility Operating License to the Office of the Federal Register for publication.
Please note that Enclosure 1 to Entergy's letter dated March 18, 2011, "Valcor Engineering Corporation's Similarity Report MR526-6040-22-3 Revision B," is declared to be proprietary in nature and not available to the public.
-2 This correction does not change the NRC staff's conclusions regarding Amendment No. 233 for Waterford Steam Electric Station, Unit 3. We regret any inconvenience caused by this error.

1.0 INTRODUCTION
8y application dated February 22, 2010 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML100550463), as supplemented by letters dated June 8 and August 12, 2010, and January 4, March 7 and March 18, 2011 (ADAMS Accession Nos. ML101620462, ML102300177, ML110070026, ML110670210, and ML11115A159, respectively), Entergy Operations, Inc. (Entergy, the licensee), requested changes to the Technical Specifications (TSs) for Waterford Steam Electric Station, Unit 3 (Waterford 3). The supplemental letters dated June 8 and August 12, 2010, January 4, March 7, and March 18, 2011, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the U.S. Nuclear Regulatory Commission (NRC) staffs original proposed no significant hazards consideration determination as published in the Federal Register on April 20, 2010 (75 FR 20633).
The amendment would add valve SI-4052A (Reactor Coolant Loop (RCL) 2 Shutdown Cooling (SDC) suction inside containment bypass isolation) and valve SI-40528 (RCL 1 SDC suction inside containment bypass isolation) to TS Table 3.4-1, "Reactor Coolant System Pressure Isolation Valves." This bypass line equalizes the SDC system pressure downstream of valve SI-405A (RCL 2 SDC suction inside containment isolation) and valve SI-4058 (RCL 1 SDC suction inside containment isolation) in order to minimize the pressure transient in the system when valves SI-405A(8) are opened.
2.0 REGULATORY EVALUATION
Section 182a of the Atomic Energy Act requires applicants for nuclear power plant operating licenses to include TSs as part of the license. The TSs ensure the operational capability of structures, systems, and components that are required to protect the health and safety of the public. The NRC's regulatory requirements related to the content of the TSs are contained in Title 10 of the Code of Federal Regulations (10 CFR), Section 50.36, "Technical specifications,"
Enclosure 2
- 8 battery capacity calculations verified that the Class 1 E batteries have sufficient capacity to support SBO for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. Offsite power or the emergency diesel generator is credited for restoration of AC power to the plant ending the 4-hour SBO event. Once AC power is restored, the safety-related battery chargers provide DC power to the DC buses and loads.
The NRC staff concludes that Waterford 3's response for SBO coping is in accordance with 10 CFR 50.63 and consistent with the guidance provided in NUMARC 87-00 and RG 1.155; and is, therefore, acceptable.
3.3.1.2 Evaluation of the Environmental Qualification of the Valves SI-4052A(B) and Associated Components In its letters dated January 4 and March 7, 2011, the licensee provided details on the environmental qualification (EQ) of valves SI-4052A(B) and the associated components. The licensee also provided a Valcor (valve vendor) similarity report, titled "Similarity Qualification Test Report on Solenoid Valve, Part Number 214167301, Model Number V526-6040-22.,,1 For Waterford 3, valves SI-4052A(B) will be procured to withstand the environmental and accident conditions inside containment as shown in the Waterford 3 FSAR Table 3.11-1, "Environmental Condition Summary." The proposed valves have not been tested for qualification but a similarity report has been submitted by the licensee that describes the similarities and differences between the proposed valve and similar valves which have been previously tested and qualified. This is consistent with 10 CFR 50.49(f)(2), which states, Testing a similar item of equipment with a supporting analysis to show that the equipment to be qualified is acceptable.
The NRC staff reviewed the similarity analysis and the staff's observations are as follows:
The licensee has procured Valcor (the vendor of the proposed valves) valves with Model Number V526-6040-22, for Waterford 3. The licensee stated that these valves are specified as Class 1E, qualified to IEEE Standard 323-1974, "IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations," Seismic Category 1, Borated Water Service. EGS (another vendor) type Conduit Seal. Radiation Environment 5.1x107 Rads. and with independent limit switches (2) normally open and (2) normally closed. To qualify this model, Valcor used two comparable valves to evaluate for similarity using the following items:
- Type of technology used in design and manufacture
- Type of critical components
- Mounting/orientation and type of connections
- Service conditions
- Safety functions The similarities for various type tests for qualifications, such as DeSign Basis Event environmental and seismic qualification, are extended to the Waterford 3 model because of Kowalewski, J. A., Entergy Operations, Inc., letter to U.S. Nuclear Regulatory Commission, "Waterford 3 Transmittal of Proprietary Valcor Report," dated March 18, 2011 (ADAMS Accession No. ML11115A159); Attachment 1 is non-publicly available.
