Letter Number: 2.11.034 Pilgrim Nuclear Power Station Pilgrim Nuclear Power Station License Renewal Application - Supplemental Information Entergy provides the following clarifying information to address questions discussed with the NRC staff on a teleconference held on April 26, 2011 regarding the following areas at Pilgrim Nuclear Power Station (PNPS).

0 Aging Management of Low and Medium-Voltage Cables Commitment No. 15 is being revised to be consistent with the Pilgrim License Renewal Application (LRA) Updated Final Safety Analysis Report (UFSAR) Section A.2.1.21, Non-EQ Inaccessible Medium-Voltage Cable Program revised in Entergy Letter 2.11.031, dated April 22, 2011 [Reference (6)].

License Renewal Commitment #15 is revised to read as follows; Commitment No. 15 Implement the Non-EQ Inaccessible Medium-Voltage Cable Program as described in LRA Section B.1.19.

Inspections for water accumulation in manholes containing in-scope inaccessible low-voltage and medium-voltage cables with a license renewal intended function will be performed at least annually. Additional condition-based inspections of these manholes will be performed based upon natural events for a coastal site. The inspection results will be reviewed to determine the need for more frequent inspections.

Inaccessible medium and low-voltage (400 V to 2 kV) cables with a license renewal intended function are included in this program. Inaccessible medium and low-voltage cables will be tested for cable insulation degradation prior to the period of extended operation (PEO) and at least once every six years after entering the PEO. A proven, commercially available test will be used for detecting deterioration of the insulation system of low and medium-voltage inaccessible cables with a license renewal function. Review test results to determine the need for more frequent testing.

This includes applying the appropriate Fen factors to valid CUFs determined in accordance with one of the following:

1.

For locations, including NUREG/CR-6260 locations, with existing fatigue analysis valid for the period of extended operation, use the existing CUF to determine the environmentally adjusted CUF.

2.

More limiting PNPS-specific locations with a valid CUF may be added in addition to the NUREG/CR-6260 locations.

3.

Representative CUF values from other plants, adjusted to or enveloping the PNPS plant specific external loads may be used if demonstrated applicable to PNPS.

4.

An analysis using an NRC-approved version of the ASME code or NRC-approved alternative (e.g.,

NRC-approved code case) may be performed to determine a valid CUF.

During the period of extended operation, PNPS may also use one of the following options for fatigue management if ongoing monitoring indicates a potential for a condition outside the analysis bounds noted above:

1)

Update and/or refine the affected analyses described above.

2)

Implement an inspection program that has been reviewed and approved by the NRC (e.g.,

periodic nondestructive examination of the affected locations at inspection intervals to be determined by a method acceptable to the NRC).

3)

Repair or replace the affected locations before exceedinq a CUF of 1.0.
