Subject:

Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 Proposed Alternative to American Society of Mechanical Engineers Code Section Xl Visual Examination Requirements Associated With Third Ten-Year Interval Inservice Inspection Program (Request No. BV3-IWVE1-4)

Approval to perform an alternative visual examination for the Beaver Valley Power Station (BVPS) Unit No. 1 third ten-year interval inservice inspection program was requested in a July 27, 2005 letter (number L-05-127) to the NRC. Additional information regarding the examination and test sequence related to the subject proposed alternative visual examination requirements was requested in an October 24, 2005 telephone call from Mr. Tim Colburn, NRC Project Manager for Beaver Valley Power Station (BVPS).

Enclosure I provides the requested information. Regulatory commitments are listed in Enclosure 2 of this submittal. If there are any questions concerning this matter, please contact Mr. Gregory A. Dunn, Manager, Fleet Licensing at 330-315-7243.

ENCLOSURE 1 L-05-164 EXAMINATION AND TEST SEQUENCE A summary list of examinations and tests to be performed for containment liner restoration welds is provided below. Examinations and tests listed in Items 1 through 4 will be performed to verify the integrity of the welds prior to restoration of concrete on the containment liner exterior surface and subsequent pressure testing.

Planned In-Process Examination and Testing Sequence

1. Perform Visual (VT) examinations and either Magnetic Particle (MT) or Dye Penetrant (PT) testing of the completed steel liner plate weld and attachment welds.

2. Perform spot Radiographic Testing (RT) examination of the completed full penetration steel liner plate weld.

3. Perform Vacuum-Box testing of the completed full penetration steel liner plate weld.

4. Perform VT- 1 examinations of the welds and surrounding areas of the restored containment liner plate interior and exterior surfaces.

5. Perform a General Visual or a VT-3 examination of the inside surface of the containment liner plate after coatings are applied.

6. Perform 10 CFR 50 Appendix J, Type A pneumatic leakage test of the containment pressure retaining boundary after restored reinforced concrete has attained proper strength.

ENCLOSURE 2 L-05-164 COMMITMENTS The following list identifies those actions committed to by FirstEnergy Nuclear Operating Company (FENOC) for Beaver Valley Power Station (BVPS) Unit No. 1 in this document.
