License Renewal Outage Commitments Inspection Plan I' PURPOSE This plan specifies licensee outage activities to be inspected in order to verify license renewal (LR) commitments and proposed conditions of license are properly implemented. In addition, this plan specifies licensee outage activities to be inspected in order to verify the structural integrity of the primary containment. The plan also provides guidance for inspection scheduling, inspection activities, and resources.
II INSPECTION OBJECTIVES (1) Verify "outage-only" SER proposed license conditions are adequately implemented.
(2) Verify selected outage related SER LR commitments are adequately implemented.
(3) Assess AmerGen's actions to evaluate structural'integrity of the primary containment.
(4) Verify revisions and changes to outage related LR commitments, made after the SER was issued, were performed in accordance with AmerGen's commitment management program.
(5) Verify that any changes to the current licensing basis (CLB), that materially affects the LR application, pursuant to § 54.21 (b), were reviewed and evaluated in accordance with § 54, for outage related commitments.
III INSPECTION REQUIREMENTS Assess AmerGen's actions to evaluate (1) structural integrity of the primary containment, (2) any actual or potential corrosion rates are projected through the next operating cycle, and (3) significance of any water in the two floor trenches located inside the drywell.
Inspect a sample of outage activities, including modifications, maintenance, testing, and inspections, that implement aging management programs (AMPs) and time-limited aging analyses (TLAA) from existing, enhanced, and new programs. Assess AmerGen's implementing activities and examine records, to independently evaluate the effectiveness of AmerGen's aging management activities and programs. For the selected outage related inspection samples, verify that:
(1) AmerGen completed the necessary actions to comply with the SER proposed license conditions, and implemented the AMPs and TLAA in the SER.
(2) AmerGen followed the guidance in NEI 99-04 for LR commitment changes, including the elimination of commitments, and properly evaluated and reported, where necessary, changes to commitments which will be listed in the UFSAR, in accordance with § 50.59.
(3) AmerGen identified and evaluated CLB changes and revised AMPs, in accordance with § 54.21(b).
IV INSPECTION SCOPE On a Sampling Basis Verify or assess licensee'activities associated with the proposed license conditions and commitments listed below. This inspection effort is not intended to require inspector back shift (evening or night) coverage.
Outage-only SER Proposed License Conditions to be Inspected 4th Proposed License Condition: Perform full scope inspections of the drywell sand bed region every other refueling outage. This will be verified by completion of inspection samples for Commitment 27, listed below.
5th Proposed License Condition: Monitor drywell trenches every refueling outage to identify and eliminate the sources of water and receive NRC approval prior to restoring the trenches to their original design configuration. This will be verified by completion of inspection samples for Commitment 27, listed below.
Outage Related LR Commitment Items to be Inspected SER Commitment 24, One-Time Inspection Program SER Commitment 27, ASME IWE, Containment Metallic Liner Inservice Inspection SER Commitment 31, Structures Monitoring Program SER Commitment 32, RG 1.127, Inspection of Water-Control Structures SER Commitment 33, Protective Coating Monitoring and Maintenance Program SER Commitment 34, Non-EQ Electrical Cables and Connections SER Commitment 36, Non-EQ Inaccessible Medium Voltage Cables SER Commitment 41, Periodic Inspection Program SER Commitment 44, Metal Fatigue of Reactor Coolant Pressure Boundary SER Commitment 63, Buried Piping V INSPECTION GUIDANCE Based on outage schedule changes and back shift work, direct observation of in-field work activities may not be achievable for all of the inspection samples listed below. This inspection plan does NOT intend that all of the possible inspection samples listed below will be accomplished.
Each inspector should prioritize his inspection efforts to provide an optimum inspection sample coverage, based on AmerGen work schedules. The following GUIDANCE is provided for inspection samples which are expected to be available during our scheduled on-site inspection.
Tim O'Hara
- 1. Inside the drywell at sand bed region elevations, inspect licensee's drywell shell thickness (UT) and Service Level I Coating verifications. Independently assess shell and coating conditions, and compare to licensee inspection records. Not intended to observe 100% of all NDE data taking.
- 2. Inside the drywell in the 2 floor trenches, inspect licensee's drywell shell thickness (UT) and Service Level I Coating verifications. Independently assess shell and coating conditions, and water accumulation, if any. Independently assess caulk seal at the trench edge where the concrete meets the shell. Compare observations to licensee inspection records. Not intended
to observe 100% of all NDE data taking.
- 3. Inside the drywell, inspect licensee's visual inspection of moisture barrier seal between drywell shell and concrete floor curb inside drywell. Independently assess seal conditions, and compare to licensee inspection records. Not intended to observe 100% of all NDE data taking.
- 4. Outside the drywell, in the sand bed bays, inspect licensee's shell thickness (UT) and Service Level II Coating verifications. Independently assess shell and coating conditions, and compare to licensee inspection records. If schedule permits, independently inspect or observe licensee activities in Bay No. 1, 11, and 13. Not intended to observe 100% of all NDE data taking, and not intended to enter or inspect all sand bed bays.
- 5. Outside the drywell, in the sand bed bays, inspect licensee's visual inspection of moisture barrier seal between the sand bed concrete and the embedded drywell shell. Independently assess seal conditions. Independently assess overall conditions in the sand bed bays.
Compare observations to licensee inspection records. Not intended to observe 100% of all NDE data taking, and not intended to enter or inspect all sand bed bays.
- 6. As time allows, review 100% of the NDE data and inspection records (UT & VT data sheets) for above items. Compare UT data against licensee established acceptance criteria.
- 1. Backup for Tim's inspection items (especially item 6, UT data review).
- 2. Inside the upper drywell at 23' (transition from 0.770" plate to 1.154" plate), 51', 60', 71' (knuckle region, transition from 2.625" plate to 0.640" plate), and 87' elevations, inspect licensee's drywell shell thickness (UT) and Service Level I Coating verifications. Choose elevations and samples based, in part, on schedule, availability, and ALARA. Independently assess shell and coating conditions, and compare to licensee inspection records. Not intended to observe 100% of all NDE data taking.
At the 23' and 71' elevations, 4 locations (6"x6" grids) at each elevation will be UT inspected. At each elevation, 2 of the 4 locations are new (no pre-existing data). At least one inspection sample should be from either the 23' or 71' elevation.
Compare UT data against licensee established acceptance criteria.
VT inspections. Verify licensee's inspection results are acceptable. Verify grout is reinstalled.
- 5. For the Fatigue Monitoring Program, verify whether any fatigue program inputs have changed base line calculations; verify whether the list of high cumulative usage factor (CUF) components changed. If locations on vulnerable components have changed, that may require a visual inspection or review of the component. Perform direct inspection as necessary.
- 6. For the Isolation Condenser, inspect licensee's One-Time Inspection of two stainless steel pipe sections in stagnant or low flow areas in the Isolation Condenser System, to verify no stress corrosion cracking. [this item may already have been performed, and may not be in this outage]
- 7. For the Isolation Condenser, inspect licensee's One-Time Inspection UT of the "B" Isolation
