Enclosure REQUEST FOR ADDITIONAL INFORMATION REGARDING THE RELIEF REQUESTS AND PROPOSED ALTERNATIVES FOR THE INSERVICE TESTING PROGRAM 10-YEAR UPDATE FIRSTENERGY NUCLEAR OPERATING COMPANY FIRSTENERGY NUCLEAR GENERATION CORP.
BEAVER VALLEY POWER STATION, UNIT NO. 1 DOCKET NO. 50-334 By letter dated March 28, 2007, Agencywide Documents Access and Management System (ADAMS) accession number ML070890491, FirstEnergy Nuclear Operating Company (FENOC, licensee) requested approval of proposed alternatives and relief requests associated with the inservice testing (IST) program fourth 10-year interval update for the Beaver Valley Power Station, Unit No. 1 (BVPS-1). There was a total of 14 requests submitted. The Nuclear Regulatory Commission (NRC) staff is reviewing the submittal and has the following questions:
Relief Request PRR3:
1.
The NRC staff realizes that Code Case OMN-9 is not applicable to the code edition that you are using. However, please state if your proposed alternative testing meets the requirements of Code Case OMN-9. If it does not meet the requirements, please state the differences.
Relief Request PRR4:
2.
Please verify that the proposed alternative includes a minimum pump time of 2 minutes, in order to achieve stable performance parameters before recoding data during the test.
Relief Request PRR5:
3.
The basis given for the relief request is NUREG-1482, Rev. 1, Section 5.6 Operability Limits of Pumps. Section 5.6 references IST-5220, which is applicable to vertical line shaft centrifugal pumps, not positive displacement pumps. Please provide a basis for relief applicable to positive displacement pumps.
Relief Request PRR8:
4.
In the last paragraph of the Components Affected Section, the licensee states, "This Request for Relief may also be applied to any pump in the IST Program scope should a vibration reading of <0.05 in/sec be obtained as a new reference value subsequent to repair or replacement." NUREG/CP-152, "Smooth-Running Pumps," Session 4, Pages 4-32, July 1996, states, "If the licensee intend to submit alternative requests to use minimum reference values, the request should be pump specific and include justification as to how the current inservice testing methodology will detect pump degradation." The NRC staff position is to review relief requests on a case-by-case basis for a specific requirement of the Code. Generic relief for all pumps cannot be authorized. Generic changes to Code requirements can be achieved through the American Society of Mechanical Engineers (ASME) Code for Operation and Maintenance of Nuclear Power Plants (OM Code) committee. Therefore, please revise the relief request to delete the last paragraph from the "Component Affected" Section. Also, future relief requests may be submitted to NRC, if historical data of the pump shows that reference value of vibration is less than 0.05 in/sec.
5.
The licensee is requesting relief for various pumps at BVPS-1. The ASME OM Code acceptance criteria of vibration for various pumps are different for various type of pumps, as specified in various Tables IST-5100-1, IST-5200-1, and IST-5300-1. The various pumps are (1) Centrifugal pump (except vertical line shaft centrifugal pumps) and (2) Vertical line shaft centrifugal pumps; and positive displacement pumps (except reciprocating). Therefore, please provide the type of each pump listed in the relief request.
6.
Please provide the following information related to each pump: (a) system in which pump is installed; (b) description of pump; and (c) Group A or Group B (pump's group based on its function as specified in ASME OM Code).
7.
The relief request does not address pump operating speed. Pump operating speed is a critical component in the vibration acceptance criteria. Please provide operating speed of each pump listed in the relief request.
Relief Request PRR11:
8.
Please provide shutoff head data from the manufacturer for the two inside recirculation pumps and two outside recirculation pumps. The manufacturer pump curves attached to the relief request do not include pump head data at zero flow rate.
9.
The licensee states that as an alternative to measuring at least five points for the preservice test, over a range from pump minimum flow rate to at least pump design flow rate, as required by IST-3100(b) and IST-5210(a), the five points will be obtained within approximately 41 percent of the design flow rate and within approximately 38 to 40 percent of the maximum required accident flow rates. From this statement, it is not clear that licensee will measure pressure at the pump minimum flow rate. If data will not be taken at pump minimum flow rate, please provide the basis.
Relief Request PRR13:
10.
Why is replacing transmitter LR-1CW-101 with level indication calibrated to 0.5%
considered a hardship or unusually difficult? Are there any temporary flow instruments that have the accuracy required for the comprehensive or preservice tests?
11.
Please provide the river water pumps suction static pressure.
12.
Please provide the river water pumps discharge pressure and the accuracy of the discharge pressure gauge.
