Dear Mr. Sena:

By letter dated August 27, 2007, FirstEnergy Nuclear Operating Company submitted an application pursuant to 10 CFR Part 54, to renew the operating licenses for Beaver Valley Power Station, Units 1 and 2, for review by the U.S. Nuclear Regulatory Commission (NRC or the staff). The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review. Further requests for additional information may be issued in the future.

ENCLOSURE BEAVER VALLEY POWER STATION (BVPS), UNITS 1 AND 2 LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION (RAI) SECTIONS B.2.3 AND B.2.5 RAI B.2.3-4

Background:

LRA Section B.2.3 states that the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section XI, Subsection IWE inspections have identified containment liner plate deficiencies such as paint flaking, chipping, blistering, and other minor damage. The application further stated that the inspections have been effective in identifying minor irregularities on the inside surface of the liner plate before significant corrosion damage occurred.

Issue:

In 2006, during a steam generator replacement, three locations of corrosion were discovered on the concrete side of the containment liner. These were attributed to degradation during initial construction, and the locations were either repaired or identified for future inspections. On April 23, 2009, during an IWE inspection, a paint blister was discovered, which upon further inspection revealed through-wall corrosion of the containment liner.

Request:

Explain how the recent plant-specific operating experience, both the 2006 and 2009 degradation, will be incorporated into the ASME Section XI, Subsection IWE AMP, and whether or not a plant-specific program is necessary to manage aging of the containment liner.

RAI B.2.3-5

Background:

During a presentation to the ACRS sub-committee, on February 4, 2009, the applicant stated that their ASME Section XI, Subsection IWE Program had been enhanced in response to the degradation discovered in 2006.

Issue:

The applicant has not discussed the relationship, if any between an enhanced IWE Program and an augmented IWE Program.

Request:

Explain how the IWE Program was enhanced, with a focus on how the enhancements relate to the ASME Code required augmented inspections. The explanation should be in sufficient detail to allow for a one to one comparison between an enhanced IWE Program and the augmented inspections required by ASME Section XI, Subsection IWE.

RAI B.2.5-1

Background:

During a steam generator replacement in 2006, three areas of corrosion were identified on the concrete side of the containment liner. In response to previous license renewal RAIs, the applicant explained that when visual examinations detect indications of degradation, surface or volumetric examinations will be performed on suspect areas of the liner plate.

Issue:

On April 23, 2009, during an IWE inspection, a paint blister was discovered, which upon further inspection revealed through-wall corrosion of the containment liner. During the applicants inspection of the corrosion, a piece of wood was discovered in the concrete behind the containment liner, which the applicant has indicated may have led to degradation of the containment concrete.

Request:

Explain whether or not the concrete or rebar, located behind the through-wall flaw, were degraded. Also explain how the recent plant-specific operating experience will be incorporated into the ASME Section XI, Subsection IWL AMP, and whether or not a plant-specific program is necessary to manage aging of the containment concrete.
