This was implemented in I Ri 3. Of the 20 Inspections performed during the first period only 12 inspections are credited to the total inspections.

2 Relief Request 13R-03 was approved to use the BWRVIP guidelines for examining these welds. No counts will be recorded for these categories.

3 Inspections are only required when components are disassembled; no percentages will be determined for this category.

4 Examinations reported in the second period were credited for both the first and second period. The first number is the examinations credited for the first period and the second number is credited for the second period. The percentage for the first period includes the examinations reported in the second period but credited to the first period.

5 The remainder of the examinations will be completed during the remainder of the second period and reported In the next report.

6 The total number of components changed during the second period based on the PRA update.

7 The examinations performed for item number E .11 bolting will not be recorded in the examination totals or the percentages because these inspections are only performed when the bolting is disconnected.

8 The code requirement is to complete the examination every 5 years, since the Inspections can only be completed during an outage the examinations are completed every 4 years. The code percentages are not required for this category.

9 There are no components contained in this category. The suppression pool inspection for the coatings maintenance plan Identified a number of plates that will be classified IWE Category E-C In the next period.

10 Examinations for item number E1.20 are only required once per interval. These examinations were completed In 1RI 3 and 1R14 however, the examinations are not counted in the completion percentage for Category E-A.

II The total examinations for Category R-A do not include the VT-2 inspections on socket welds that are completed each outage.

12 Credit is only taken for one of the components inspected during this period.

Section 2: Summary of Conditions Observed As a result of the examinations performed during the Limerick Generating Station Unit 1, Refuel Outage 14, there were no new indications requiring flaw evaluations that are reportable to the NRC, either by ASME Section XI requirements or BWRVIP protocol. Numerous other conditions were recorded and subsequent examinations and/or evaluations determined all conditions to be either non-relevant or geometric in nature.

The following is a summary of the significant indications identified during the inspections.

Component Reference Description and Resolution HBC-152-003F IR 1173559 Pinhole leak identified on ESW piping.

C0236858 Replaced piping on 3/9/11 HBC-143-03 IR 1114013 Pinhole leak identified on ESW piping.

C0236810 Base metal repair performed on 3/11/11 HBC-082-01 IR 1244448 Pinhole leak identified on ESW piping.

C0239201 Base metal repair performed during 1R14 HBC-141-04 IR 1293854 Pinhole leak identified on ESW piping.

00240743 Base metal repair performed during 1R14 Component Reference Description and Resolution 10S199-DWH IR 1332997 Indications Identified on Drywall Head Several indications were identified on the drywell head:

1. Bolt support between 51 and 52 has apparent impact damage.

2. Paint is chipped between all of the bolts.

3. Paint is chipped at various locations on the IDand OD of the head.

Evaluated to be acceptable until a coating repair in 1R15.

APE-iMS-HHA1 IR1333019 Support nut has a slight gap on one side; the other side is tight Evaluated tobe acceptable, a straight edge determined the nut was not misaligned.

DCA-101 -H003 IR1338149 The variable support was found outside the acceptance criteria.

Determined to be a failure; the cause was concluded to be the initial setup of the support. The support, has two spring cans that do not carry the piping load equally. The as found loads were reversed in the field. The support was reworked to return the support to the design condition.

Code Case N-586-1 reviewed the other supports on Feedwater, RWCU, Main Steam, and Reactor Recirculation and determined no other support had a configuration similar to this support, no additional inspections were required.

Successive examinations were scheduled for the next period.

DCA-185-E01-HO01 IR 1335559 The variable supports were found outside the acceptance criteria.

DCA-185-EO1 -H005 Determined to be a failure; the supports were reworked to return the supports to the design condition.

Code Case N-586-1 determined the cause to be previously performed physical work on the piping caused a change in the load set. The scope expansion was to inspect the other drain lines off Reactor Recirculation that had physical work completed. The scope expansion was 5 additional supports.

Successive examinations were scheduled for the next period.

DCA-1 77-EO1 -H007 IR 1336918 Additional examination for IR 1335559; variable support was found outside the acceptance criteria.

Determined to be a failure; the support was reworked to return the support to the design condition.

No additional scope expansion because the support was part of the targeted scope expansion identified in the Code Case N-586-1 evaluation for IR 1335559.

Successive examination was scheduled for the next period.

GBB-1 12-HOOI IR 1330590 Examination found no lock nuts on the support base. Review of the installation specification determined lock nuts were not required. The support was installed per the installation specification.

GBB-1 12-H901 IR 1330591 Examination found no lock nuts on the support base. Review of the installation specification determined lock nuts were not required. The support was installed per the installation specification.

HBB-120-H023 IR 1331128 Examination identified minor surface defects in the concrete under the support's base. An evaluation determined the defects did not affect the structural Integrity of the support. The support is acceptable in the as found condition.

HBC-138-H025 IR 1335829 Examination identified the support gap was too large. A re-examination of the gaps determined the gaps were acceptable; the support is acceptable in the as found condition.

VRR-1 RS-HHA7 IR 1332450 Examination Identified the support rod was touching the grading; no indications were observed on the support rod. The support was determined to be acceptable and the grading was moved.

During the Lil R1 4 refueling outage an inspection was performed of the submerged portion of the suppression pool. This inspection was performed per the Coating Maintenance Plan.. The ISI inspection of the submerged portion of the suppression pool (Category E-A Item E1.12 "Wetted Surfaces of Submerged Areas') will be completed during the third-period of the second interval for Containment ISI (1 R15 or 1 R16).

Limerick Specification NE-1 01 contains the criteria for a metal repair of the liner. A metal repair of the liner is required for any localized areas of general corrosion less than 2.5 inches in diameter with a depth of 187 mils and for areas larger than 12.5 inches in diameter with a depth of 125 mils. For areas between 2.5 and 12.5 inches in diameter the depth can be determined using a table in, NE-1 01; these areas will be greater than 125 mils in depth. The acceptance criteria for the coating maintenance plan islocal recoating of areas with general corrosion that exhibit greater than 25 mils plate thickness loss, spot recoating of localized corrosion greater than 50 mils deep, and recoating of plates with greater than 25 percent coating depletion. The following components failed to meet one or more of the-new criteria. Plates or components that ate equal to the acceptance criteria have also been added to the list.

Procedure ER-AA-330-007 was used to evaluate the condition. The procedure requires an evaluation in accordance with 10CFR50.55a shall be performed to determine the acceptability of the degradation in the inaccessible locations.

This evaluation was performed under IR 1364843-A04 and is attached below.

DOCUMENT NO.: IR# 1364843-04 TITLE: Evaluation of Degradation in Unit 1 Suppression Pool Inaccessible Areas PREFACE:

This Technical Evaluation is performed in accordance with CC-AA-309-101, Rev. 13. The Limerick Suppression Pool is safety related; therefore, an IndePendent Review will be performed. A Pre-Job Brief and Technical Task Risk/Rigor Assessment was performed for this evaluation in accordance with HU-AA-1212, Rev. 4. This review identified a Risk Rank of 3 (independent review by off-site specialist), based on a "Medium" Consequence Risk Factor and a "High" Probability of Error. A review of the Design Attribute Review (DAR), CC-AA-1 02, Rev. 23, was performed, which verified that no design considerations and impacts were identified.

REASON FOR EVALUATION / SCOPE During the Lil R1 4 refueling outage, an inspection was performed of the submerged portion of the suppression pool. This inspection was performed per the Coating Maintenance Plan. The ISI inspection of the submerged portion of the suppression pool (ASME Section XI (reference 1).Category E-A Item El. 12 "Wetted Surfaces of Submerged Areas') will be completed during the third period of the second interval for Containment ISI (1 RI 5 or 1R16)..

The inspection performed for the Coating Maintenance Plan identified degradation in inaccessible areas of the liner plates. The areas are classified inaccessible because the visual inspection cannot meet.the inspection angles due to other components obstructing the view or other components were too close to the surface indication. These areas are behind the RHR and Core Spray Suction Strainers; under the RHR Suction Strainers, and around other structural components.

Since the Coating Maintenance Plan inspections identified degradation in the inaccessible areas, procedure ER-AA-330-007 (reference 2) was used to evaluate the condition. The procedure requires an evaluation in accordance with 10CFR50.55a shall be performed to determine the acceptability of the degradation in the inaccessible locations; 10CFR50.55a (reference 3) requires the following items be addressed:

1. Description of the type and estimated extent of the degradation, and the conditions that led to the degradation.

2. Evaluation of each area and the results of each evaluation.

3. Description of the necessary corrective actions.

This evaluation will perform the 10CFR50.55a evaluation for the degradation identified in the inaccessible areas of the submerged portion of the Limerick Unit I Suppression Pool.

DETAILED EVALUATION The suppression pool is designed to have a metal liner that is supported by concrete. The liner is designed as a membrane pressure barrier. The liner function is to increase the containment integrity with regard to the ability to retain gasses and water within the containment during normal and accident conditions. A protective coating was sprayed on the liner to protect the liner from corrosion. The suppression pool liner is 1/4-inch (250 mils) carbon steel that is coated with a porous zinc coating.

The zinc coating protects the metal surface because the zinc preferentially sacrifices itself to the corrosion. As the zinc corrodes, the amount of protection of the metal surface decreases; and once the zinc is depleted, the protection stops. A number of locations in the Limerick Suppression Pool have depleted the zinc coating. With the loss of the protective coating, some areas have started to corrode.

An evaluation of the corrosion of the Limerick Suppression Pool was performed by Structural Integrity Associates, titled "Corrosion Evaluation of the Limerick Mark II Containment (reference 4). This evaluation determined the corrosion occurring in the Limerick Suppression Pool is general corrosion (rust). This corrosion can be general over a large area or localized (pitting) over a smaller area.

The inspection of the submerged portion of the suppression pool is performed by qualified divers. These inspectors perform a general visual (VT-3) inspection of the liner to identify areas of degradation. The inspectors then perform a detailed visual (VT-1) inspection of the degraded areas to determine the metal loss of the degraded areas. To perform a VT-1 inspection the angle must be greater than 30-degrees from the plane of the component being inspected per ER-AA-335-014, VT-1 Visual Inspections (reference 5). Additionally, the VT-1 inspection uses depth gages to measure the metal loss on the plates. Procedure ER-AA-335-018, Visual Examination of ASME IWE Class MC and Metallic Liners of CC Components (reference 6), describes these inspections. The results of the inspections are compared to the owner defined pre-established acceptance criteria.

The Limerick acceptance criteria are contained in the Limerick. Specification NE-101 (reference 7). The general corrosion allowance before requiring a metal repair, is:

General metal loss over a large area (with a diameter greater than 12.5 inches) greater than 125 mils.

Localized metal loss (diameter less than or equal to 2.5 inches):greater than 187.5 mils.

During the 1R1i4 inspection of the suppression pool, liner plates, a number of areas were identified to have corrosion but qualified VT-1 inspections could not be performed due to the angle of inspection. Procedure ER-AA-330-007 requires an evaluation in accordance with 10CFR50.55a(b)(2)(ix)(A) shall be performed to determine the acceptability of the degradation in these inaccessible locations.

10CFR50.55a(b)(2)(ix)(A)

For Class MC applications, the licensee shall evaluate the acceptability of inaccessible areas when conditions exist in accessible areas that could indicate the'presence of or result in degradation to such inaccessible areas.

For each inaccessible area identified, the licensee shall provide the following in the ISI Summary Report as required by IWA-6000:

1. A description of the type and estimated extent of degradation, and the conditions that led to the degradation

2. An evaluation of each area, and the result of the evaluation, and

3. A description of necessary corrective actions Description of Degradation Corrosion identified in the suppression pool is general area corrosion, spot corrosion, localized general corrosion, and tiger striping.

General Corrosion: Also known as "uniform corrosion". This term refers to corrosion that completely coversa surface of more than several square inches. Metal loss is generally uniform across the exposed area and typically does not involve much section loss.

Spot Corrosion: Spot corrosion is simply general corrosion that presents itself as localized "spots" of exposed substrate on a coated surface. Spots are generally less'than a few square inches each but

-may be up to several square inches. Metal loss is generally uniform across each exposed area and typically does not involve much section loss. Spot corrosion should not be confused with pitting corrosion.

Localized General Corrosion (Pitting): Pitting is defined as localized corrosion with an accelerated metal loss rate. Pits present themselves as small, localized cavities in the metal surface. Pitting tends to progress rapidly through the plane of the metal rather than spread along its surface. Pits can be found individually or in large groups.

0 Tiger Striping: Relative to coatings in immersion service, tiger striping is a condition unique to inorganic zincarich coatings. It is a coating condition that is found on vertical surfaces, typically in stagnant, underwater conditions. In the early stage, it appears in alternating vertical light and dark stripes within the coating itself. The light stripe usually acts as the cathode and the dark stripe as the anode. Over time, zinc in the anodic areas is depleted/consumed giving way to corrosion of the substrate. It is essentially general corrosion in dense vertically aligned corrosion nodules. Like general corrosion, associated metal loss is typically minor.

Evaluation by Area The corrosion rates of the Limerick Unit 1 Suppression Pool have been very low. This is due to the inert atmosphere of the suppression pool during plant operations and the water quality of the suppression pool. The corrosion of the submerged portion-of the suppression pool liner is being trended by the establishment of several corrosion evaluation grids. Inspections of these areas were performed during outages in 1996 and 2004 for Limerick Unit 1. The data obtained from these inspections suggests that the liner metal with no coating is experiencing an average general corrosion rate of approximately I to 2 mils per year. This data was obtained during underwater suppression pool liner inspections using depth gauges, including compensation for remaining coating thickness on surfaces adjoining the grid areas with material loss (reference 8).

The inspectors identified degradation in the inaccessible areas behind several obstructions during the 1 R14 inspection. The inspectors performed an unqualified observation of the degraded areas in the inaccessible areas because the inspection angle was less than the 30 degree angle required by station procedures.

Although the inspection was unqualified the inspectors were able to perform an assessment of the condition of the degradation in the inaccessible areas. The inspectors concluded the conditions in the inaccessible areas could be considered visually consistent with conditions reported for adjacent accessible areas (reference 9).

The following is a list of the inaccessible areas, the type of corrosionidentified, a description of the corrosion adjacent to the inaccessible areas, and the area of the plates. This information was obtained from the 1R14 inspection report (reference 10) and Limerick drawing C-0281 (reference 11).

Several other areas were not inspected due to the storage of the vacuum filters and structure. Assignment IR 1364843-06 was generated to develop plans to inspect these areas during the next suppression pool inspection.

Corrective Actions The station is implementing two corrective actions:

Action 1 - Develop a method to perform remote insoections of the inaccessible areas.

This action is to develop a method to perform remote inspections of the inaccessible areas around the ECCS suction strainers. If a method can be developed the area will no longer be inaccessible. The degradation will be monitored as all the accessible areas and the requirements of Limerick Specification NE-101 will be followed.

Action 2 - Remove the suction strainers to oerform insMections and recoat as reeuired.

Ifa remote inspection of the inaccessible areas cannot be performed, the station will remove two suction strainers each outage to make the inaccessible areas accessible. The selection of the suction strainers for removal will be based on the condition of the accessible areas around the suction strainers. If adverse conditions are identified during the inspection of the inaccessible areas, the inspection scope will expanded to the other suction strainers. When a suction strainer is removed, the degraded areas will be inspected to determine the extent of the corrosion. After the areas are inspected, the areas will be recoated to stop the corrosion.

CONCLUSIONS I FINDINGS The visual examinations performed on the Suppression Chamber liner surfaces were performed in accordance with the requirements of the Coatings Maintenance Plan. As such, areas that could not be viewed at an angle greater than 30-deg from the plane of the component being inspected (e.g., behind and/or around ECCS strainer components) were documented as 'Inaccessible Areas.' No condition assessment was documented on the examination records since adequate visual access for a qualified VT-1 Inspection could not be achieved in these areas. In general, based on interviews with various inspectors, conditions in these "Inaccessible Areas" could be considered visually consistent with conditions reported for adjacent accessible areas.

The review of the accessible areas adjacent to the inaccessible areas found the deepest wail loss was 30 mils and the deepest floor loss was 25 mils. Limerick Specification NE-101 determined the liner is acceptable with a defect in a localized area less than or equal to 187.5 mils and a metal loss in a general area of less than or equal to 125 mils. Due to the water quality and the inert atmosphere during plant operations the corrosion rate of the Limerick Unit 1 Suppression Pool is very low.

The areas adjacent to the inaccessible areas had corrosion significantly less than the 187.5 mils (localized corrosion) and 125 mils (general corrosion). With the low corrosion rate continued operation with the corrosion in the inaccessible areas is acceptable. During the next refuel outage (1R15) the corrective actions will be implemented to either remotely inspect the inaccessible areas or remove two suction strainers to inspect and recoat the degraded areas.
