SUBJECT:
Beaver Valley Power Station, Unit Nos. 1 and 2 Docket No. 50-334, License No. DPR-66 Docket No. 50-412, License No. NPF-73 10 CFR 50.55a Request Regarding Motor Operated Valve Testing Pursuant to 10 CFR 50.55a, FirstEnergy Nuclear Operating Company (FENOC) hereby requests Nuclear Regulatory Commission (NRC) approval of Valve Relief Request VRR1, Revision 1 for the Beaver Valley Power Station, Unit No.1 (BVPS-1) fourth interval Inservice Testing Program for Pumps and Valves (1ST Program) and the Beaver Valley Power Station, Unit No. 2 (BVPS-2) third interval 1ST Program. Request VRR1 is associated with testing of motor-operated valve assemblies included in the Beaver Valley Motor-Operated Valve Program and was previously authorized for BVPS-1 by NRC letter dated September 27, 2007 (Accession Number ML072420376) and for BVPS-2 by NRC letter dated February 14, 2008 (Accession Number ML080140299).
Revision 1 of VRR1 for both BVPS-1 and BVPS-2, specifies the version of Code Case OMN-1 to be implemented and provides a list that identifies affected motor-operated valve assemblies. In addition, wording is changed to make the text of VRR1, Revision 1, consistent for both BVPS-1 and BVPS-2, and includes additional applicable code requirements.
FENOC requests approval of VRR1, Revision 1, by December 15,2012. There are no regulatory commitments contained in this letter. If there are any questions or if additional information is required, please contact Mr. Phil H. Lashley, Supervisor - Fleet Licensing, at (330) 315-6808.

-Alternative Provides An Acceptable Level Of Quality And Safety-ASME Code Motor-operated valve (MOV) assemblies included in the Beaver Valley Component(s) MOV Program and listed in the attached table.
Affected:
Applicable Code American Society of Mechanical Engineers (ASME) Operation and Edition and Maintenance (OM) Code-2001 Edition, with Addenda through OMb-Addenda: 2003.
Applicable Code ISTA-3130, "Application of Codes Cases," ISTA-3130(b) states that Requirements): Code Cases shall be applicable to the edition and addenda specified in the test plan.
ISTC-3100, "Preservice Testing," states in part that any valve that has undergone maintenance that could affect its performance after the preservice test shall be tested in accordance with ISTC-3310.
ISTC-3310, "Effects of Valve Repair, Replacement, or Maintenance on Reference Values," states in part that when a valve has been replaced, repaired, or has undergone maintenance that could affect the valve's performance, a new reference value shall be determined, or the previous reference value reconfirmed by an inservice test (1ST) run before the time it is returned to service.
ISTC-3510, "Exercising Test Frequency," states in part that active Category A, Category B, and Category C check valves shall be exercised nominally every 3 months.
ISTC-3520, "Exercising Requirements," ISTC-3521 states in part that active Category A and B valves shall be exercised during cold shutdowns if it is not practicable to exercise the valves at power, or that active Category A and B valves shall be exercised during refueling outages if it is not practicable to exercise the valves during cold shutdowns.
ISTC-3700, "Position Verification Testing," states in part that valves with remote position indicators shall be observed locally at least once every two years to verify that valve operation is accurately indicated.
ISTC-5120, "Motor-Operated Valves," ISTC-5121(a) states that active valves shall have their stroke times measured when exercised in accordance with ISTC-3500.
Reason for NUREG-1482, Revision 1, Section 4.2.5 states in part:
Request:
... As an alternative to MOV stroke-time testing, ASME developed Code Case OMN-1, "Alternative Rules for Preservice and Inservice Testing of Certain Electric
Beaver Valley Power Station, Unit Nos. 1 and 2 10 CFR 50.55a Request Number: VRR1, Revision 1 Page 2 of 10 Motor-Operated Valve Assemblies in LWR [Light Water Reactor] Power Plants," which provides periodic exercising and diagnostic testing for use in assessing the operational readiness of MOVs.,.
The following Nuclear Regulatory Commission (NRC) staff recommendation is also provided in Section 4.2.5:
The NRC staff recommends that licensees implement ASME Code Cases OMN-1 ... as accepted by the NRC (with certain conditions) in the regulations or [Regulatory Guide] RG 1.192, as alternatives to the stroke-time testing provisions in the ASME Code for applicable
[power operated valves] POVs.
Section 4.2.5 provides a basis for the recommendation that states in part:
RG 1.192 allows licensees with an applicable Code of record to implement ASME Code Case OMN-1 (in accordance with the provisions in the regulatory guide) as an alternative to the Code provisions for MOV stroke-time testing, without submitting request for relief from their code of record.... Licensees with a code of record that is not applicable to the acceptance of these Code Cases may submit a request for relief to apply those Code Cases consistent with indicated conditions to provide an acceptable level of quality and safety.
The Code of record for Beaver Valley Power Station, Unit No. 1 (BVPS-1) fourth 10-year inservice test interval, and Beaver Valley Power Station, Unit No. 2 (BVPS-2) third 10-year inservice test interval is ASME OM Code-2001 Edition through OMb-2003 Addenda and the applicable Code for OMN-1, as stated in RG 1.192, was only reaffirmed through the OMa-1999 Addenda.
Proposed Implement Code Case OMN-1 from the ASME OMb Code, 2006 Alternative and Addenda, in lieu of MOV stroke-time provisions specified in ISTC-5120, Basis for Use: preservice testing provisions of ISTC-3100, reference value provisions of ISTC-3310, exercising test frequency provisions of ISTC-3510, and exercising provisions of ISTC-3520. Code Case OMN-1 has been determined by the NRC to provide an acceptable level of quality and safety when implemented in conjunction with the conditions imposed in RG 1.192. Also, implement the provisions specified in ISTC-3700 in conjunction with the MOV diagnostic test frequency (specified in the 1ST Program Valve Tables) in lieu of the ISTC-3700 frequency of once every two years.
Using the provisions of this relief request as an alternative to MOV stroke-time testing provisions of ISTC-5120, preservice testing
Beaver Valley Power Station, Unit Nos. 1 and 2 10 CFR 50.55a Request Number: VRR1, Revision 1 Page 3 of 10 provisions of ISTC-3100, reference value provisions of ISTC-3310, exercising test frequency provisions of ISTC-3510, exercising provisions of ISTC-3520, and position verification frequency provisions of ISTC-3700, provides an acceptable level of quality for the determination of valve operational readiness. Code Case OMN-1 from the ASME OMb Code, 2006 Addenda, should be considered acceptable for use with ASME OM Code-2001 through OMb-2003 as the Code of record.
Duration of The proposed alternative identified in this relief request shall be utilized Proposed during the BVPS-1 fourth 10-year inservice test Interval, and BVPS-2 Alternative: third 10-year inservice test interval.
