in scope medium voltage cables Will be tested to provide an indication Of thes on ditioteon of the conductor insulation. In this aging management program, periodic actions are taken, at least once every two (2) years, to minimize cable exposure to significant moisture, such as inspecting for water collection in cable manholes, and drainin water, as needed. In-scope, medium-volta-ge cables exposed to significant moisture and significant volta-ge are tested to provide an indication of the condition of the conductor insulation.
The specific type of test performed will be determined prior to the initial test, and is to be a proven test for detecting deterioration of the insulation system due to wetting, such as power factor, partial discharge, or other testing that is state-of-the-art at the time the test is performed.

NUREG-1801 Consistency The Inaccessible Medium-Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program is a new program that is consistent with NUREG-1801,Section XI.E3, Inaccessible Medium-Voltage Cables Not Sub/ect to 10 CFR 50.49 Environmental Qualification Requirements.
Exceptions to NUREG-1801 None Enhancements None Aging Management Program Elements The results of an evaluation of each of the 10 aging management program elements described in NUREG 1800 [Ref renGe 1.3 4, Appendix A, NUREG-1801,Section XI.E3, are provided as follows:
- Scope of Program The program is applicable to inaccessible, non-EQ medium-voltage cablessuitable fe m
Gee that support a license renewal intended function and are exposed to significant moisture simultaneously with significant voltage.
The program defines "significant moisture" as periodic exposure to moisture that lasts more than a few days (e.g., cable in standing water). Periodic exposure to moisture, which lasts less than a few days (i.e., normal rain and drain) is not significant.
The program defines "significant voltage" as being subject to system voltage for more than twenty-five percent (25%) of the time, The moisture and voltage exposures described as significant in these definitions, which are based on operating experience and engineering judgment, are not significant for medium-voltage cables that are su#able desiqned for these conditions (i.e., submarine cables). -The frV.DSr in scope nmediumg voltage Gables have boen determined to be srhitablo for subm*rgencc; thcrcforge, no aging effe~t Feq "~ng magmnt was identified qfo these Gables.
Enclosure L-09-138 Page 16 of 20 Preventive Actions This program includes periodic actions to minimize cable exposure to significant moisture. The program identifies the applicable manholes and will require inspection of these manholes at least once every two (2) years to inspect for water collection in cable manholes, and draining of water as needed..

water-troes. an indication of the condition of the conductor insulation. The program allows that the specific type of test performed will be determined prior to the initial test, and is to be a proven test for detecting deterioration of the insulation system due to wetting, such as power factor, partial discharge, as described in EPRI guidance documents, or other testing that is state-of-the-art at the time the test is performed.
Through manhole inspections, accessible portions of cables will be inspected for visual indications of water induced damage.
- Detection of Aging Effects Testing of the cables will be performed at least once every ten (10) years, with the first test to be completed prior to the period of extended operation. This is an adequate period to preclude failures of the conductor insulation since experience has shown that aging degradation is a slow process. A ten (10) year testing interval will provide two data points during a twenty (20) year period, which can be used to characterize the degradation rate. This testing will provide an indication of the condgitin Of the cond~uctor-4nsuiation. The specifi type of test to be perfor~ed will be frtMirId prirF t* the ft'I test, and is t be a rt/t fpof t

This inspection will identify visual indications of water induced damage.
Water identified in the applicable manholes will be drained at the time of inspection to facilitate visual inspection of the cables.
The program identifies the applicable manholes and will require inspection of these manholes at least once every two (2) years. The inspection frequency will be based on actual plant experience with water accumulation in the manhole, with the first inspection to be completed prior to the period of extended operation.
Enclosure L-09-138 Page 17 of 20
- Monitoring and Trending Trending actions are not included as part of this program because the ability to trend results is dependent on the specific type of test chosen. However, all test and inspection results will be maintained as part of plant records. Therefore, these results are available for review and/or trending during subsequent tests and inspections as needed.
- Acceptance Criteria Testing acceptance criteria will be defined by the specific type of test performed and the specific cable tested.
Visual inspection acceptance criteria will provide that the accessible portions of the cables are to be free from visual indications of surface anomalies.
- Corrective Actions The program will require that unacceptable cable test/inspection results are to be documented in the BVPS Corrective Action Program. Any subsequent engineering evaluations and extent-of-condition determinations are conducted according to the Corrective Action Program.
This element is discussed further in Section B.1.3.
- Confirmation Process This element is discussed further in Section B.1.3.
- Administrative Controls This element is discussed further in Section B.1.3.
- Operating Experience The Inaccessible Medium-Voltage Cables Suitable for Submerngence and Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program is a new plan peGifi Beaver Valley Power Station aging management program for which there is no plant-specific operating experience for program effectiveness.
Industry operating experience that forms the basis for the program, as described in the operating experience element of the NUREG-1801,Section XI. E3 program description, B VPS plant-specific operating experience is consistent with the operating experience element of the NUREG-1801,Section XI.E3 program description. Industry and plant-specific operating experience will be considered in the development and implementation of this program. As additional operating experience is obtained, lessons learned will be appropriately incorporated into the program.
Enclosure L-09-138 Page 18 of 20 BVPS currently has a manhole inspection procedure, which provides for the identification of water induced damage to cables and cable supports contained in manholes. The BVPS manhole inspection procedure was performed in 2008. The results of the procedure are documented in the Corrective Action Program. The findings included missing seals, cracked walls, corroded supports, and water intrusion. No cable damage was found. The associated work order indentifies varying amounts of water in in-scope manholes, with some in-scope manholes having water levels above the cable level.
A 20-08 engnerig aluation has con firmed that in scope mqedium voltage cables arc suitabe for operation. in sub-gmerged environmgents.

In the response to NRC Generic Letter 2007-01, "Inaccessible or Underground Power Cable Failures That Disable Accident Mitigation Systems or Cause Plant Transients," FENOC reported that BVPS has not experienced failure of inaccessible or underground power cables within the scope of 10 CFR 50.65.
The lack of cable failures and the lack of cable degradation support the cable testing frequency of at least once every ten (10) years.
Conclusion The implementation of the Inaccessible Medium-Voltage Cables Su÷witable for Subm.ergence an Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program will provide reasonable assurance that the aging effects will be managed so that the systems and components within the scope of this program will continue to perform their intended functions consistent with the current licensing basis for the period of extended operation.
