The description should include when the inspections were performed; the areas, penetrations and steam space piping connections inspected; the extent (percentage) of coverage achieved for each location which was inspected; the inspection methods used; the process used to resolve any inspection findings; the quality of the documentation of the inspections (e.g., written report, video record, photographs); and, the basis for concluding that your plant satisfies applicable regulatory requirements related to the integrity of pressurizer penetrations and steam space piping connections. If leaking pressurizer penetrations or steam space piping connections were found, indicate what follow-up NDE was performed to characterize flaws in the leaking penetrations.
Entergy Response to Request 1(b):
ANO RCS/Pressurizer Inspection Program - At ANO, Entergy utilizes ANO Procedure 2311.009, ANO Unit I and Unit 2 Alloy 600 Inspection, to facilitate inspections concerned with Alloy 600 primary water stress corrosion cracking (PWSCC). The procedure contains guidance for inspection of the specific small bore and pressurizer nozzles that are susceptible to PWSCC for both units. The procedure identifies specific RCS locations that to OCAN070404 Page 6 of 9 are to be inspected and documents and corrects leaks from Alloy 600 components. The procedure specifies a 360 degree inspection around the nozzle 'annulus.
Other program controls include the ANO-1 and ANO-2 ASME Section Xl Inservice Inspection programs (CEP-ISI-002 and CEP-ISI-004, respectively) that include the examination of welds, rigid restraints and pressure boundaries of components and piping on Class 1, 2 and 3 systems. The weld and rigid restraint examinations are performed during the specified periods. Prior to returning the units to operation, ANO Quality Control procedures (5120.242 and 5120.243) are used for the Post Outage Pressure Test for Unit 1 and Unit 2, respectively for performing a VT-2 inspection of the RCS pressure boundary.
During plant cooldown and heatup walkdowns, Operations and Quality Control personnel perform an inspection of the RCS to document any leakage including signs of boric acid deposits. A list of boric acid leakage sites is compiled from the walk down and evaluated for repair. Each leak path evaluation is assigned an evaluation number and tracked to resolution. Repairs are performed under the ANO Work Order process and condition reports are generated, as appropriate.
Generic Letter (GL) 88-05, Boric Acid Corrosion of Carbon Steel Reactor Pressure Boundary Components in PWR Plants, required four areas to be considered for ensuring that licensees boric acid inspection processes were adequate to identify reactor coolant pressure boundary (RCPB) leakage that could degrade carbon steel piping and components. The ANO boric acid program has been established under procedural control for compliance to our commitments for GL 88-05 as well as site wide improvements in boric acid identification and control.
Alloy 600 butt welds that connect piping or instruments to the pressurizer nozzles have not been specifically identified for inspection on a refueling outage basis. However, the walkdowns associated with the Alloy 600 and boric acid program would identify boric acid leakage from these locations because the end of the nozzles are only a few inches from the external surface of the pressurizer, and removal or repositioning of the insulation to allow visual examination of the nozzle/vessel interface would also expose the end of the nozzle and the associated butt welds. ANO has not experienced any Alloy 600 weld failures of piping or instruments connected to the pressurizer nozzles.
Previous ANO Pressurizer Inspection Findings and Repairs -
ANO In December 1990, while performing a repair on a pressurizer level tap isolation valve during power, a leak on the associated instrument nozzle was identified. Non-destructive examination of the nozzle was conducted, which indicated an axially oriented flaw of approximately 0.4 inches in length. A partial nozzle repair was performed using an Alloy 600 nozzle and weld material. There have been no other identified Alloy 600 nozzle or weld failures associated with the ANO-1 pressurizer.
ANO In April 1987, a containment entry was made to inspect an ANO-2 safety injection tank. It was subsequently identified that pressurizer heater sleeves X1 and T4 were leaking and the unit was shutdown to perform the repair. It was suspected that a particular heater design of 23 of the heaters could have hastened sleeve failure. The other 21 suspect heaters were removed and the sleeves inspected and found to not have similar flaws. The two leaking sleeves were removed and the penetration was plugged.
to OCAN070404 Page 7 of 9 During a mid cycle outage ihlJuly 2000, while ANO 2 was in cold shutdown for inspection of the steam generators, boric acid was discovered on the cables of two heaters (B2 and D2).
Insulation was removed from all of the heaters to perform additional inspection. It was discovered that ten additional heater sleeves (AA3, A2, B4, D4, D3, B3, C3, AA4, B1, and G2) exhibited similar evidence of leakage. Eight of the sleeves had heaters installed, while four of the sleeves had dummy heaters. Nine of the twelve leaking heater sleeves were located in the first row around the pressurizer surge line nozzle, which is in the middle of the bottom head. Eddy current examination of two of the heater sleeves (C3 and D3) revealed a single, through-wall, axial crack in both sleeves below the J-groove weld that joins the sleeve to the cladding on the inside surface of the pressurizer. All heaters were removed and were plugged with Alloy 690 plugs.
During 2R1 5 in April 2002, six Alloy 600 ANO-2 pressurizer heater sleeves were discovered to be leaking. Five of these heater sleeves (C2, El, E2, F4, and Gl) were identified during plant cooldown while the remaining leaking heater sleeve (N2) was discovered during plant heatup. A second generation Mechanical Nozzle Seal Assembly (MNSA-2) was installed on each of the six leaking pressurizer heater sleeves which restored the pressure boundary integrity of the sleeves. Since the apparent failure was consistent with previous heater sleeve failures, no additional nondestructive examination was performed.
There have been no instrument line failures on the ANO-2 pressurizer.
Basis for Concluding that Your Plant Will Satisfy ADplicable Regulatory Requirements:
Entergy has established an Alloy 600 nozzle inspection program, which is performed on a refueling outage basis in accordance with site procedures. In addition, the ISI program inspections, required by 10CFR50.55a and ASME Section Xl, do support interval based piping integrity. Entergy has established RCS integrity program inspections that assure that pressure boundary leaks will be detected and repaired. Based on the ASME Code required inspections, the Alloy 600 program inspections, as well as the GL 88-05 inspections, Entergy has confidence that the ANO pressurizer nozzle inspections provide RCS integrity and meet all regulatory requirements.
NRC Request 1 (c): A description of the Alloy 82/1821600 pressurizer penetration and steam space piping connection inspection program that will be implemented at your plant during the next and subsequent refueling outages. The description should include the areas, penetrations and steam space piping connections to be inspected; the extent (percentage) of coverage to be achieved for each location; inspection methods to be used; qualification standards for the inspection methods and personnel; the process used to resolve any inspection indications; the inspection documentation to be generated; and the basis for concluding that your plant will satisfy applicable regulatory requirements related to the structural and leakage integrity of pressurizer penetrations and steam space piping connections. If leaking pressurizer penetrations or steam space piping connections are found, indicate what follow-up NDE will be performed to characterize flaws in the leaking penetrations. Provide your plans for expansion of the scope of NDE to be performed if circumferential flaws are found in any portion of the leaking pressurizer penetrations or steam space piping connections.
to OCAN070404 Page 8 of 9 Entergy Response to NRC Request 1(c): Entergy at ANO will continue to perform bare metal visual inspections of pressurizer-penetrations in accordance with Procedure 2311.009 in future refueling outages for those penetrations that contain Alloy 600 material. Procedure 2311.009 will be revised to include inspection of other pressurizer Alloy 600 nozzle to stainless steel connections not previously inspected. If leakage is found on ANO-2 Alloy 600 pressurizer heater sleeves, Entergy will perform additional NDE to characterize the degradation present in the leaking penetration in accordance with the January 30, 2004 Westinghouse Owners Group letter and NRC Bulletin 2004-01. Entergy is planning to replace the ANO-2 pressurizer by the fall 2006 refueling outage with improved Alloy 690 material. Entergy also intends to replace the ANO-1 Alloy 600 J-welded pressurizer nozzles and stress improve the butt welded joints.
NRC Request 1 (d) In light of the information discussed in this bulletin and your understanding of the relevance of recent industry operating experience to your facility, explain why the inspection program identified in your response to item (1)(c) above is adequate for the purpose of maintaining the integrity of your facility's RCPB and for meeting all applicable regulatory requirements which pertain to your facility.
Entergy Response to NRC Request 1(d): The proposed actions by Entergy for ANO, meet the expectations requested by Bulletin 2004-01 and are considered appropriate for maintaining the integrity of ANO's RCPB. Entergy's inspection program meets applicable regulatory requirements which pertain to ANO.
NRC Request 2: Within 60 days of plant restart following the next inspection of the Alloy 82/1821600 pressurizer penetrations and steam space piping connections, the subject PWR licensees should either (a) submit to the NRC a statement indicating that the inspections described in the licensee's response to item (1)(c) of this bulletin were completed and a description of the as-found condition of the pressurizer shell, any findings of relevant indications of through-wall leakage, follow-up NDE performed to characterize flaws in leaking penetrations or steam space piping connections, a summary of all relevant indications found by NDE, a summary of the disposition of any findings of boric acid, and any corrective actions taken and/or repairs made as a result of the indications found, or (b) if the licensee was unable to complete the inspections described in response to item (1)(c) of this bulletin, submit to the NRC a summary of the inspections performed, the extent of the inspections, the methods used, a description of the as-found condition of the pressurizer shell, any findings of relevant indications of through-wall leakage, follow-up NDE performed to characterize flaws in leaking penetrations or steam space piping connections, a summary of all relevant indications found by NDE, a summary of the disposition of any findings of boric acid, and any corrective actions taken and/or repairs made as a result of the indications found.
