To: DennisGirroir 5/15/2001 From Ralph Connell Re: Report for TWE Inspections Performed for RF022 (Reference Report for IWE Inspections Performed for WOZl dated 12/02/1999)
XNTRODUCTIOIY:
The objective in the current period for this new IWE inspection program was to gather as much information as we could for W021 and RF022. During RF021 the goal was to perform as many inspections as possible within the acceptable window without causing any interference with other outage work activities. The remahder of the required first period examinations was performed either before or during RF022.
After the IWE examinations performed during RFO 21 the Program Procedure PP7024 was revised to incorporate lessons learned. Some revisions were made to the appendices regarding inspected components and inspection criteria. As a result some of the examinations originally listed for the 1 period were revised and are reflected in the completion schedule included in this report. All required VI-3 examinations were moved to the 3d period as required by the ASME Section XI[ Code 1992/92A.
DISCUSSION:
The ASME Section XI Subsection ][WE Code requires an examination of the coated surfaces in order to determine the condition of the substrate. This examination of coated surfaces is for evidence of flaking, blistering, peeling, discoloration and other signs of distress of the underlying metal. The IWE examinations performed for W021 found only two areas of coating with signs of distress affecting the substrate. Those two areas were located at the drywefl interior moisture barrier and the other was on the drywell surface at the X-5G penetration. Both of these were evaluated by Mechanical Design Engineering and dispositions provided via the IDR process. IWE examinations during W 0 2 2 identified two more areas. These were areas of pitting and corrosion in the vent header and corrosion in the interior of penetrations X-207A-H. Both of these were also evaluated by Mechanical Design Engineering and dispositions provided via the LDR process. At many areas of the containment there is peeling or discoloration. Both of these issues have been previously identified and accepted via the OP5250 inspections.
The Maintenance Department has been perfiiming containment inspections for several years via OP5250 to evaluate the condition of the coatings on containment surfaces.
These inspections have compiled an excellent source of data documenting the conditions of the coatings and how these coatings are maintaining over time. The information provided fkom these reports provides the basis for disposition of issues identified on the IWEreports such as coating peeling and blistering.
Several areas were identified as inaccessible during the RF021 and RF022 IWE examination process. Those inaccessible areas are generally defined in PP7024. More specific information is included with the data supplied in this report.
DETAILS:
TORUS SURFACE The d a c e ffom just below the catwalk on the exterior surface to the horizontal mid point of the toms was inspected prior to IZF022 The remaining torus penetrations were examined prior to W022 and during RF022.
Penetrations X-207A-H were identified as having corrosion exceeding the provided acceptance criteria. IDR 01-08 was written on this item. This was addressed by Design Engineering and a design wall thickness for these penetrations was provided. The X-207A-H penetrations are acceptable for continued use and the corrosion identified does not exceed the required design wall thickness.
Torus penetration (includes penetrations in the vent system) examinations were completed for the first period.
The interior surface of the vent header examination was completed during RF022. There were areas of pitting and corrosion identified in the vent header that exceeded the provided acceptance criteria. IDR 01-07 was written to address the areas of pitting and corrosion Design Engineering addressed this IDR and provided new acceptance criteria for the vent header corrosion identified. All areas a e within the required design wall thickness provided by the Design Engineering resolution and are acceptable for Continued operation.
After review of the data gathered during W021, a portion of the containment surface at the joint seal area was declared as augmented. This area was examined and documented during RF022. No change was identified in the as inspected condition between RF021 and RF022 in the augmented area.
Since the area of the augmented s d c e was being prepared for seal installation and painting the opportunity to exmine this region with white metal exposed and all corrosion removed presented itself The entire circumference in the moisture barrier area was examined and the areas of pitting and pit depths were identified. All pitting
identified by this examination were bounded by the 1999 evaluation, VYM 99/139, and are acceptable for continued operation of the drywell.
Forty-three (43) percent of the required first period drywell penetration examinations were completed during RF021 the remainder was examined either prior to or during RF022. Many of these penetrations depicted debris and peeling paint. The diddebris is not considered to be detrimental to the containment structure. All penetration cavities were dry with no visible indication of moisture. The peeling paint was similar to that identified in the maintenance reports and is not unumal for the age and environmental conditions experienced by the coating.
The dirt/debris identified in the drywell penetration cavities is a housekeeping issue only, not a containment integrity concern. All large debris located in the penetrations examined has been removed. The remaining debris consists ofthe accumulation of dirt, dust and paint chips over the Iife of the plant. The quantity of debris in the penetrations identified is not a containment integrity concern. Most dddebris was lying in the concrete sleeve and not in contact with the penetration. All penetrations examined (except for X-207A-H) were dry with no indication of water. The penetrations typically have a small access and pose difficulty cleaning. The dilemma fiom inside the drywell is the accessibility to the penetrations and the ALARA cqncerns.
The drywell moisture barrier at the concrete floor to steel interface on the 238 level was identified as failed during RF021 examination. During RFO 22 this seal was replaced.
To deal with the paint chipping and corrosion in the seal area and to accommodate the seal installation a six-inch wide band of paint was removed in the seal area for the 111 circumference of the drywell at the 238 level. The seal was reinstalled per minor mod
- 2000-010.The six-inch band was re-coated with non-qualified coating. The area ofthe seal and coating was examined after installation to document the as installed condition.
This seal acts as a gasket at the concrete to steel interface to prevent moisture from penetrating under the concrete and to prevent it fkom setting in the interface setting up localized corrosion. This area is an area that regularly gets flooded with water due to the activities that take place during outages in the dry well. This area also is an area that experiences wear and tear at a much higher rate than the rest of the containment due to its location. As a result of the location and outage activities this is an area that requires regular maintenance to keep the moisture barrier seal and the paint in the moisture barrier area intact and properly protecting the steel containment. The logistics of trying to place qualified coating at this location and then set up to regularly maintain it can be difficult as was seen during RF022 not to mention very costly. X recommend that this moisture barrier area and the six-inch band of paint be declared a high maintenance area and designed as an area where unqualified coatings are approved and utilized. This will make the routine maintenance of this area much easier to perform resulting in better
maintenance of this area in the fitlare. If this approach were approved, repahting with qualified coating would not be required only maintenance activity to maintain the integrity of the non-qualified paint and moisture barrier seal. This maintenance should become a routine PM.
PRESSURERETkMNG BOLllNG Bolting examinations for X-200A & B and V16-19-5G& H were completed during W022 in the removed condition. Bolting examinations for V16-19-SA-F was examined in place. This completes the required first period IWEbolting examinations.
An estimated 80% of IWE examinations are completed prior to or during RFO21. The remaining 20% were completed prior to or during RF022 to complete the first period examination requirements.
There were two new IDRs generated, per DP4027, or contahment issues during RF022. All of these issues were addressed by Mechanical Design Engineering prior to RF022 startup.
Please find attached to this report for reference the Summary of First Period IWE Examinations. This repod provides details for the first period examinations.

To: DennisGirroir 12/02/1999 From: Ralph Connell Re: Report for IWE Inspections Performed for W021 INTRODUCTION:
The objective in the current period for this new NVE inspection program was to gather as much information as we could for RF021 and RF022. During RF021 the goal was to perform as many inspections as possible within the acceptable window without causing any interference with other outage work activities. The remainder of the required first period examinations will be scheduled for RFO22. An estimated 80% of the required first period examinations have been completed at the cbmpletion of RF02 1.
DISCUSSION:
The ASlwE Section XI Subsection MTE Code requires an examination of the coated sUTfaCes in order to determine the condition of the substrate. This examination of coated surf'aces is for evidence of flaking, blistering, peeling, discoloration and other signs of distress. The TWE examinations performed for W021 found only two areas of coating with signs of distress affecting the substrate. Those two areas were located at the drywell interior moisture barrier and the other was on the drywell surface at the X-5G penetration. Both of these were evaluated by Mechanical Design Engineering and dispositions provided via the IDR process. At m y iireas of the drywell there is peeling or discoloration. Both of these issues have been previously identified and accepted via the OP5250 inspections.
The Maintenance Department has been peri?o&g containment inspections for several years via OF5250 to evaluate the condition of the coatings on containment surfaces.
These inspections have compiled an excellent source of data documenting the conditions of the coatings and how these coatings are maintaining over time. The information provided from these reports provides the basis for disposition of issues identified on the IWEreports such as coating peeling and blistering. In all cases, except for the two areas specifically identified at the joint seal and the SG-penetration area, the peeling and blistering coating is a condition that applies to the outer epoxy coating. The primer coat remains intact providing acceptable protection of the metal surfaces.
Several areas were identified as inaccessible during the RF021 IWE examhation process. These inspection reports shall be reviewed for detail and validity. After the review the program procedure wilI be revised to recognize the inaccessible areas in the program, PP7024.
There were fiReen examhation reports rejected due to housekeeping concern. One report was a VT-3 for X-206A external surface, eigh for X-207A through H internal
t surface, two for X-9A & B external surface, and four for X-7A through D external surface. All of these examinations shall be rescheduled for inspection before or during RF022 after cleaning. There are also housekeeping issues on a portion of the external torus surface below the catwalk, which also require cleaning and reinspection.
DETAXLS:
TORUS SURFACE The torus inspections covered approximately 94% of the accessible Surface for general visual examination. Underwater locations are considered inaccessible for general visual examination. The Surface %om just below the catwalk on the exterior surface to the horizontal mid point of the torus was not inspected. This surface requires cleaning before it can be properly examined. A work order request has been submitted to perform this cleaning. The remaining 6% of this Surface can be inspected with the plant on line and should be completed prior to W 0 2 2 if cleaning is performed.
The underwater surface areas were completed in RF020 using VT-1 criteria. These inspections were performed prior to the formal development of the IWE program. In order to be conservative, VT-1 examinations were specified in anticipation of this area being classified as Category E-C augmented examination. The review of the torus inspection data generated fiom 1998 revealed that during the twenty-five plus years of operation there were no significant areas of general corrosiodmetal loss identified.
Therefore it may be concluded that the interior surface of the torus is not subject to accelerated corrosion and no augmented examination are required at this time. The IWE program as written reflects this philosophy. This is not to say that the torus will never be classified as Category E-C, but that classification, if necessary, will be the result of finding areas that are subject to accelerated corrosion. The scheduled TWE examinations will provide regular examinations of the torus and that data will be evaluated for applicability to Category E-C. The result of performing VT-1 and UT examinations was that it provided excellent baseline data. The VT-1 examinations performed during RF020 exceed the required IWEVT-3 examinations of the applicable surfaces.
IDR 99-07 provides the disposition for an area on torus bay 4 where metal was removed.
This area on bay 4 appears to be &om original construction and does not violate the minimum required thickness in this area OT the code referenced 10%. This area is acceptable as is. Reference VYM 99/147 for the complete details of this evaluation.
The examinations required for the first period have completions of 80% for the general visual inspections and 100% for the scheduled VT-3 exams. The vent header external surface, downcorners internal and downcomers external surfaces were completed during RF020 inspections using VT-1 examinations. The vent lines were completed during RF021. The exterior of the vent lines outside the torus, the remainder of the vacuum breaker lines external surfaces and the vent header interior surface will be rescheduled for
general visual examination before or during RF022. Tbe remaining 20% of the required first period examinations will be rescheduled for RF022.
IDR 99-06 was generated against nine rejected examination reports for cracks in the attachment clip tack welds that holds the vacuum breaker line bellows cover in place. The cracked welds for the vacuum breaker expansion joint cover attachment clips appeared to be a configuration issue as the cause. Tbe short-term evaluation was basically use as is.
An ER was also written for the issues addressed here, ER 99-1321, and will address the long-term corrective actions for the items identified 'within IDR 99-06. VYM 991145 provides the details of this evaluation.
Torus penetration (includes penetrations in the vent system) examinations completed 90% of the requirements for the first period, The areas remaining 10% of the penetrations to be examined were in the area of the torus requiring cleaning. These penetrations will be cleaned along with the torus surface and inspections should be completed prior to RF022.
RFO21 examinations completed 100% of the accessible drywell surface. The outer surface of the drywell is inaccessible by design except for the drywe11 head, which is accessible from both sides. Except for paint issues which have been previously identified by OP5250 and found acceptable, the only other issues dealing with the containment surfkce is the corrosion identified on the containment surface at the 5G penetration and the corrosion of the containment surface in areas along the joint seal. The joint seal area corrosion is described in more detail under heading Containment Seals, Gaskets, and Moisture Barriers. Tn these two cases the paint was ciacked and peeled. Investigation of these areas identified the corrosion in these areas.
In general, the paint peeling and flaking are the results of loss of paint film adhesion of the outercoat to the primer coat. Typically the primer coating under this peeling and flaking paint is in good condition and is tightly adhered to the base metal. The discoloration are the result of leakage and work activities from past events and work activities except those noted on IDR's for m h e r engineering evaluations. The blistering identified in the coating is most likely the result of gases or liquids within or underneath the paint, which exert pressure greater than the adhesion or cohesion of the paint at the area under stress. If the rate of diffision of the solvent vapor through the paint film is slower than the rate of formation of the vapor, blistering will occur. This would have occurred during the drymg process shortly after the paint was originally applied. It is not unusual to find some ofthis type of condition in this paint system. This condition is a paint issue only and does not affect the base metal.
IDR 99-018 is for corrosion identified on the containment (drywell) surface in the area of the X-5Gpenetration. No signrfcant wall loss is identified for this area. And no further
action is required, Reference VYM 99/139 for the complete details of this evaluation.
This area shall be scheduled for cleanup and repainting during RF022.
DRYFU3.LP.ENTRAnONS Forty-three (43) percent of the required first period drywell penetration examinations were completed during RF021. Many of these penetrations depicted debris and peeling paint in the examination reports. Follow up examinations of these penetrations pefformed by the Project Engineer Responsible Engineer revealed that the debris remaining in the penetrations consisted of an accumulation of dirt and peeled paint fiom approximately twenty-six years of operation. This debris is not considered to be detrimental to the containment structure. All penetration cavities were dry with no visible indication of moisture. The peeling paint was similar to that identified in the maintenance reports and is not unusual for the age and environmental conditions experienced by the coating. The remaining 57% of these penetrations shall be inspected prior to or during RF022.
The debris identified in the drywell penetration cavities is a housekeeping issue only, not a containment integrity concern. Ali large debris located in the penetrations examined have been removed, The remaining debris consists of the accumulation of dirt, dust and paint chips over the life of the plant. The quantity of debris in the penetrations identified is not a containment integrity concern. All penetrations examined were dry with no indication of water. The penetrations typically have a small access and pose difficulty cleaning. The dilemma fiom inside the drywell is the accessibility to the penetrations and the ALARA concerns. A work order request has been originated to dean the external sleeves of the drywell penetrations. During this time we will attempt to develop an acceptable process to perform this task. If an acceptable process can be developed for the extern1 sleeves we will investigate the possibility of cleaning the drywell internal sleeves on a case by case basis.
COhTUiWENT SEALS, GASKETS, AND MOISTURE BARRlElzs The entire drywell interior moisture barrier was inspected to the VT-3 criteria. This examination revealed cracked and peeling paint with arms.of corrosion on the base metal in the seal area. The paint was cracked in the bottom of this area for 360 degrees. This area has an ER and IDR written against it.
There was one rejected report for the drywell interior moisture barrier. This report was the original VT-3 examination of this area. IDR 99-012 was generated against this report for the engineering evaluation. This IDR was evaluated by MechanicaI Design Engineering and found to be adequate as is for structurd concerns. Paint coating and seal repairs should be pedomed at the earliest opportunity. Event Report 99-1594 was Written against this area, The disposition of this ER shall provide the details required to implement the repair. VYM 99/139 provides the details of this evaluation. It is the opinion of this author that the necessary repairs for this area should take place: during
RF022. The responsible department should be identified as early as possible as well as providing the necessary scope of work. The Project Engineering Responsible Engineer shall monitor the progress of this issue and provide regular reports to the Project Engineering Program Supervisor. This area shall be. evaluated for the applicability of Category E-C augmented examination prior to the revision of procedure PP7024.
No bolting was inspected for lWE for RF021. All bolting originally scheduled for RF021 will be review for the possibility of rescheduling to RF022.
SUMMARY
Although we did not complete all IWE first period examinations during RFO21, we did meet our original objective. That objective was to gather information regarding primary containment issues relating to the IWE program and to complete as many examinations as possible without impacting other outage work activities. An estimated 80% of IWE examinations are completed for the first period. The remaining 20% shall be rescheduled for RF022 for examination or reexamination. Some of the areas to be examined will require additional coordination due to cleaning requirements or accessibility requirements to complete the examinations.
There were four new IDRs generated, per DP4027, for containment issues during RF021. All of these issues were addressed by Mechanical Design Engineering prior to RF021 startup.
Please find attached to this report for reference the Summary of First Period IWE Examinations for RF021 and the maintenance 1999 Drywell Inspection Record. These reports provide detail for examinations completed and those required to be rescheduled for RF022 and a summary of the OW250 coating examinations.

9 EVALUA?3ON 0.F DATA PROWED BY VT-1, CONTATNMENT SURFACES (rwE)
DATA SHEET No: 804541-019 During RFO 21 TWE examitTatioflsit was discovered that the Joint SeaI at the concrete to steel interfice on the 238 level ofthe containment had failed and there was evidence of corrosion in areas of the seal. As a resalt a portion of the circnmferenceof the seal interface area was declared as augmented. ?he joht seal itself was also scheduled for replacement duringRFO-22.
At the start ofW0-22 the examinersperformed;he reqniredVT-1 examinations of the augmented area at thejoint Seat to detemine ifany changes bad o c c u ~ r e dduring the last operating cycle. The results afthat examinationreveal no changes identifiedin the augmented a n a After the VT-1 examinatomwere cornprete the ptocess began for the joint seal replacement. A band of paint was removed h m the concrete floor up the steel contabment approximately6 wide for the full circumference. The recessed area for the joint seaI was aIs0 cleanedin preparation for the new seal installation. At this point a VT-3 examinationswas performed which identifieda band of pitting that covered much ofthe 3600-Begree circumference. A more detailed VT-1 was ordered by the Responsiie Engineer to detail this area prior to pamt/seaI instdlation.
Thisjoint seal area was identSed as an issue inthe early 1990s. (ER-99-1594deals with the issues from the 1990s resolution). In 1993 the joint seal area was cleaned and painted so as to form a paint joint seal at the mncfete to seal interface. The 2t~easidentifiedduring the RFO-21 examinations were areas that were experiencing evidence of corrosion and paint loss in this pdinteajointarea Some of the paint was still intad and providing adequate protection for the steel it was covering.
The new areas of pitting in the area of the joint seal are as a result of the coating removal to white metal in this area. This atea was not previously identified during RFU-21 because it was an old area of pitting that hadbeencoveredbythe1993 ~ g a n d h a d n o t e ~ ~ c e d a n y ~ e r d Asaresultofthe e~tim coatings being completely removed h m thisjoint area, this VT-1 examination was able to map this region without the impedance of any obmructioa The areas of pitting are isolated to the general area of the joint seal &&ace between the concrete and the steel. The pitting subsides as it move up or down out of thejointseal area. This was evident when a portion ofthe steel smfitce was exposed as a result of the removal of a concrete chip. The under slnface area exposed was approximately 9 wide and 3 deep in a crescent shape. The worst case pitting is isolated to a band in the joint seal areafromapproximately % wick to approximately 1 wide and is clescrii in the report as areas with general wastage and connected pitting All corrosion identifiedwithin this report is bounded by evaluation VYM 99/139.Based on this evaluation all aeas are well within the requmd design base metal t h i c a e s aed are acceptable for continued operation as is.

VERMONT YANKEE TECHNICAL EVALUATION DOCUMEWATLON Technical Evaluation No. 20016 2 5 Tile: EVALUATION OF ASME SECTION XI - IWE FINDINGS FOR IDR 01-07 & IDR 0198 El QA (SafetyCIass, OQA. or Vital Fire) 0 Non QA (Non-Safety) (Check One}
Backsround This T.E. evaluates findinas from the IWE inspections of the vent header and vent Pipe bowls in the VY primaw containment. Specificalivaddressed are Inservice Discrepancv R ~ D o ft~ DRl ~s Nos. 01-07 and 01-08, design inputs (D1)I& 2.
Visual Inspections are performed on the VY primary containment in accordance with the American Society of Mechanical Engineers (ASME) Code Section Xi,Subsection IWE. The purpose of the inspections is to identify degradation of coatings and metal waJl loss to insure the continued structural integrity of the primary containment. The inspectors use a pre-evaluated acceptance criteria, 01 (31,to screen inspection results. The pre-evaluated criteria is based on VY calculation VYC-1032, Rev.1, DI (4), it serves as a threshold for further evaluation of the results by Design Engineering.
IDR 01-07 identifiesareas of general pitting and general corrosion in the vent header and the vent pipe bowls. DI (3) requires any indications adjacent to the vent header mitre joints, downcomer intersections, and vent pipe/header intersections be forwarded to Design Engineering for evaluation.
IDR 01-08 identifies corrosion on the internal surfaces of all (8) ofthe X-207 penetrations.
These penetrations were the !ow point drain in the bottom of each vent pipe bowl. Dl's (3)& (4) do not specifically address corrosion in the X-207 penetrations. The findings were forwarded to Design Engineering for evaluation.
Discussion I DR 01-07 1DR 01-07 identifies areas of general pitting and general corrosion in the vent header and the vent pipe bowls. A summary of the findings from IDR 01-07 is attached to this TE as Table 1 I As indicated on page 1 of 9 of Data Sheet No. 8047-01-031, the pitting areas identified have a minimum separation of (3) pit diameters. Areas identified with local pitting in the vent pipe bowls and in the vent header within 4 inches of the vent pipeheader intersections require an evaluation by Design Engineering. This TE will evaluate the findings shown in Table 1 against the acceptance criteria contained in DI(4).
As shown in Table 1, localized pitting was found in the lower portions of all (8)vent pipe bowis.
The areas of pitting correspond to zones 1 and 3 as shown in Figure 27 in Attachment A of VYC-1032,Rev. 1, Di (4). Permissible size indications for these zones are given in Figures 28 and 30 from D1(4>for zones 1 and 3 respectively. The limiting zone is zone 1. All pitting in the vent pipe bowls will be evahted using an enveloping comparison for zone I.From DI (3), a pit is
, WAPF 6045.02 Ap604S.02 Qriginal Page 1 of 6
W Technical evaluation No. TE 2001-0025 defined as a small area of surface corrosion less than 0.5 inch in diameter.
To envelop pitting found in the vent pipe bowls, the allowable depth of a 1 inch diameter surface indication wiil be compared against the largest measured pit depth from Table 1, Note that the areas of localized pitting shown in Table 1 only define the areas of pitting, not a zone of wall loss. From Figure 28, for a 1 inch diameter indication an allowable depth is greater than 0.10 inch. From Table 1 the maximum pit depth for the vent pipe bowls is 0.042 inches in X-5F.
Therefore all observed pitting in the vent pipe bowls is acceptable.
To envelop pitting found in the vent header, the same approach as for the vent pipe bowls will be used. Since the pitting is adjacent to the vent pipe intersection, Figure 30 for zone 3 will be used, From Figure 30; for a 1 inch diameter indication, an allowable depth is greater than 0.12 inch. From Table 1 the maximum pit depth for the vent header is 0.042 inches adjacent to X-5F.
Therefore all observed pitting in the vent header is acceptable.
The standing water found in the in the bottom of the bowl at X-5Halong with any other standing water accumulated in the other bowls during this refueling outage will be removed prior to drywell closeout per 5/4/01 telecon with B.Tietze, VY Facilities Supervisor.
1DR 01-08 IDR 01-08 identifies corrosion on the internal surfaces of all (8) of the X-207 penetrations, X-207 A to X-207H. Dl's (3) & (4) do not specifically address corrosion in the X-207 penetrations. The results were fowarded to Design Engineering for evaluation.
Each of these penetrations was the low point drain in the bottom of each vent pipe bowl. The original design of the X-207 penetration was a 1 inch nominal pipe which extended from the bottom ofthe vent pipe bowl down to an elevation below the Torus water level. These lines were removed and the pipe stubs were capped during the Torus Mark I Program Modifications under EDCR 80-11, Details a r e shown on VY drawings No. 6202-213 and 5920-9152,Dl's (6) &
(7).
Specific calculations for required wall thickness for the X-207 penetration are not contained in the original design analysis report, Dt (5). Due to the small size of the penetration (less than 2 inch nominal) no additional reinforcement was required by the ASME Code. Drawing No. 6202-213 shows the construction details for the penetration. The penetration is a 1 inch diameter schedule 80 pipe attached to the vent pipe head using a full penetration weld and a reinforcing fillet weld. The thinnest section is the wail of the 1 inch diameter pipe stub. Using the sizing requirements from the original design code, the required thickness for pressure and applied loads wiII be determined. This will be compared against the piping wall thickness with the estimated waIl loss from IDR 01-08 as shown on Data Sheet No. 8047-01-32.
From Dl (6),the pipe is 7 inch Sch. 80 seamless pipe A333 Gr.1, with a n outside diameter of 1.315inches, and a nominal thickness of 0.179 inch. The material ultimate strength is 55 KSi.
and the code allowable stress is 13.7Ksi. The minimum installed thickness of the pipe including the +/- 12.5%manufacturing tolerance is 0.157 inch. The effective throat of the 3/16fillet weld on the cap is .707{3/16) = 0.133 inch.
WAPF 6045.02-Ap6045.02 original Page 2 of 6
VY Technical evafmtiun No. TE 2001-0025 From ASME 111 & Vllt, DI (8),the required thickness for the 56 Psi design pressure (conservative considering this is an internal component) is taken from UG-27 of ASME VJII.
With P=56. Psi., R= 1.315/2= .658inch, & SE 43,700.Psi.:
PR , 't = 56'(0*658) = 0.0027 inch.
Circumferential Stress: t=
SE- 0.6P 13700.-0.6(56)
Longitudinal Stress: t= PR , t= 56'(0'658) =Z 0.001 3 inch.
2SE -F 0.4P 2(13700.)f 0.4(56)
Given the cantilever configuration and the small size of the stub, there are minimal loads on the stub, Using a 1.0% increase to account for rnisc. loads etc., the required wall thickness for the pipe will be taken as 0.003inch.
The minimum wall thickness including the 0.025 inch estimated wall ioss from Data Sheet No.
8047-01-32, is (0.157-.025)= 0.132 inch. This is significantly greater than the 0.003 inch required wall thickness.
AssurnDtionsfOpen items NONE Material Reauirementsflrnptementation Instructions NONE Conclusions 1DR 01-07:
The localized shallow pitting found in the bottom interior surfaces of the vent header and vent pipe bowls has been evaluated against the D1 (4) acceptance criteria and found acceptable.
The preparer of this T.E.accompanied the !WE examiners on this inspection. The interior condition of the vent header appears essentially the same as observed on a pre-IW E walkdown performed on 9/23/93. During the 1993 refueling outage the vent header was cleaned and a protective coating was applied to the bottom of each bowl and at stiffener plate locations at the downcomers. These coatings are still intact. The extent of light surface corrosion and local pitting appears about the same as was observed in 1993. This indicates that most of the pitting occurred prior to 1993, and that the mechanism is not currently aggressive. Based on this, no augmented inspections would be recommended.
IDR 01-08 The estimated wall joss in each of the X-207 penetrations has been conservatbely evaluated WAPF 6045XQ *
~ ~ 6 0 4 5 . 0Original 2
Page 3 of 6
W Technical evaluation No. TE 2001-0025 against code requirements and the reamining wall is significantly greater than the code required wall thickness.
The significant margin to code minimum wall thickness and the low expected rate of gakanic corrosion in the inerted containment during operation,would support that no augmented inspections would be recommended at this time.
Recommendations
- 1. The ZOO1 refueling outage Data Sheet 8047-01-031should be used as a baseline for the next scheduled !WE inspection of the vent header interior.
- 2. The next scheduled IWE visual inspection of the exterior of the vent pipe should include a specific note to check the exterior condition of the X-207 stubs.

Discussion IDR 01-07 IDR 01-07 identifies areas of general pitting and general corrosion in the vent header and the vent pipe bowls. A summary of the findings from IDR 01-07 is attached to this TE as Table 1.
As indicated on page 1 of 9 of Data Sheet No. 8047-01-031, the pitting areas identified have a minimum separation of 13) pit diameters. Areas identified with local pitting in the vent pipe bowls and in the vent header within 4 inches of the vent pipdheader intersections require an evaluation by Design Engineering. This TE will evaluate the findings shown in Table 1 against the acceptance criteria contained in DI (4).
As shown in Table I , localized pitting was found in the lower portions of all (8) vent pipe bowls.
The areas of pitting correspond to zmes 1 and 3 as shown in Figure 27 in Attachment A of Vyc-1032, Rev. 1, DI (4). Permissible size indications for these zones are given in Figures 28 and 30 from DI (4) for zones 1 and 3 respectively. The limiting zone is zone I. AI[ pitting in the vent pipe bowls will be evahated using an enveloping comparison for zone I.From DI (31,a pit is VYAPF 6045.02 Ap6045.02 Original-Page I o f 6
VY Technical evaluation No. TE 2001-0025 defined as a small area of surface corrosion less than 0.5 inch in diameter.
To envelop pitting found in the vent pipe bowls, the allowable depth of a I inch diameter surface indication will be compared against the largest measured pit depth from Table 1. Note that the areas of localized pitting shown in Table 1 only define the areas of pitting, not a zone of wall loss. From Figure 28,for a 1 inch diameter indication an allowable depth is greater than 0.10 inch. From Table 1 the maximum pit depth for the vent pipe bowls is 0.042 inches in X-5F.
Therefore all observed pitting in the vent pipe bowls is acceptabte.
To envelop pitting found in the vent header, the same approach as forthe vent pipe bowls will be used. Since the pitting is adjacent to the ventpipe intersection, Figure 30 for zone 3 will b e used. From Figure 30; for a 1 inch diameter indication, an allowable depth is greater than 0.12 inch. From Table 1 the maximum pit depth for the vent header is 0.042 inches adjacent to X-5F.
Therefore all observed pitting in the vent header Is acceptable.
The standing water found in the in the bottom of the bowl at X-5H dong with any other standing water accumulated in the other bowls during this refueling outage will be removed prior to drywell closeout per 5/4/01 telecon with 8.Tietze, VY Facilities Supervisor.
IDR 01-08 IDR 01-08identifies corrosion on the internal surfaces of all (8) of the X-207 penetrations, X-207 A to X-207H. Dl's (3) & (4) do not specifically address corrosion in the X-207 penetrations. The results were forwarded to Design Engineering for evaluation.
Each of these penetrations was the low point drain in the bottom of each vent pipe bowl. The original design of the X-207penetration was a Iinch nominal pipe which extended from the bottom of the vent pipe bowl down to an elevation below the Torus water level. These lines were removed and the pipe stubs were capped during the Torus Mark I Program Modifications under EDCR 80-1I . Details are shown on VY drawings No. 6202-213 and 5920-9152, Dl's (6)&
(7)*
Specific calculationsfor required wall thickness for the X-207 penetration are not contained in the original design analysis report, D1 (5).Due to the small size of the penetration (less than 2 inch nominal) no additional reinforcement was required by the ASME Code. Drawing No. 6202-213 shows the construction details for the penetration. The penetration is a 1 inch diameter schedule 80 pipe attached to the vent pipe head using a full penetration weld and a reinforcing fillet weld. The thhinnesf section is .the wall of the 1 inch diameter pipe stub. Using the sizing requirements from the original design code, the required thickness for pressure and applied loads will be determined. This will be compared against the piping wall thickness with the estimated wall loss from IDR 01-08 as shown on Data Sheet No. 8047-01-32.
From DI (6),the pipe is 1 inch Sch. 80 seamless pipe A333 Gr. I, with an outside diameter of I .315inches, and a nominal thickness of 0.1 79 inch. The material ultimate strength is 55 Ksi.
and the code allowable stress is 13.7 Ksi. The minimum installed thickness of the pipe including the 4- 12.5% manufacturingtolerance is 0.157 inch. The effective throat of the 3/16 fillet weld on the cap is .707(3/16)= 0.133inch.

The localized shallow pitting found in the bottom interior surfaces of the vent header and vent pipe bowls has been evaluated against the D1 (4) acceptance criteria and found acceptable.
The preparer of this T.E. accompanied the IWE examiners on this inspection. The interior condition of the vent header appears essentially the same as observed on a pre-IWE walkdown performed on 9/23/93. During the 1993 refueling outage the vent header was cleaned and a protective coating was applied to the bottom of each bowl and at stiffener plate locations at the downcomers. These coatings are still intact. The extent of light surface corrosion a n d local pitting appears about the same as was observed in 1993. This indicates that most of the pitling occurred prior to 1993, and that the mechanism is not currently aggressive. Based on this, no augmented inspections would be recommended.
IDR 01-08 The estimated wall toss in each of the X-207 penetrations has been conservatively evaluated WAPF 6045.02
- Ap6045.02 Original Page 3 of 6
VY Technical evaluation No. TE 2001-0025 against code requirements and the reamining wall is significantly greater than the code required wall thickness.
The slgnificant margin to code minimum wall thickness and the low expected rate of galvanic corrosion in the inerted containment during operation,'would support that no augmented inspections would be recommended at this time.
recommendations 1, The 2001 refueling outage Data Sheet 8047-01-031 should be used as a baseline forthe next scheduled fWE inspection of the vent header interior.
- 2. The next scheduled IWE visual inspection of the exterior of ihe vent pipe should include a specific note to check the exterior condition of the X-207 stubs.

Title:
EVALUATIONOF IS1 PROGRAM IDR NO. 01-09, P-18-1A REACTOR REClRC PUMP BOLTING El QA (Safety Class, OQA, or VW Fire) Non QA (Non-Safety) (Check One)
Backaround This T.E. evaluates findings from the ASME Section XI inspection of the Reactor Recirculation Pump,P-18-1A, cover to case cap screws as documented on Inservice Discrepancy Report. (IDR) No. 01-09 (Attachment A). The cap screws are 2-1/2 diameter 16" long, (Part No. 2-6) with washers (Part No. 2-5 )
as shown on W drawings 5920-738 & 5920-739, design inputs (D!) Nos. 2 & 3.
The 1st visual inspection of the pump cover to case bolting is documented on Data Sheet No. 804501-016, dated 5/5/01which is attached to the IDR. Recodable findings noted on the Data Sheet are:
- 1. Coating is missing.
- 2. Corrosion exists on portion of threads where they screw into the pump casing.
- 3. Water standing in scattered areas on top of casing. {could be from small bore piping above).
To assess the degree of corrosion at the bolt locations a walkdown of the bolts on both pumps was performedby Design EngineeringMIS (J.FitzpaWck & KBeardsley) on 5/9/01. Access to both pumps was facilitated by scaffolding erected for modifications to the attached RBCCW cooling lines.
The areas surrounding the bolt heads and washers on both pumps exhibit 8 light surface corrosion. The insulation on ihe attached RBCCW cooling lines was removedfor the piping modification, this permitted easy access to the cap screw heads and the surrounding areas. See the photos in attachment 6.The general surface corrosion may be the result of condensation from the exterior of the R3CCW tines or from water draining into this area during past replacementsof the pump seals. As shown in the photos in , corrosion by-products were observed on painted surfaces above the location of the cap screw heads. Other than the general surface corrosion there is no significant amount of additional corrosion evident at the cap screw head and washer interface.
The exposed threads on the cap screw at the pump casing coverbody interface are identified as having the chrome plating degraded and as exhibitingsome surface corrosion on the e w s e d threads. There appears to be minimal metal loss on the exposed threads. From DI 4, the ASME stress report forthe pumps, there is margin in the supplied bolt area over the required bolt area. This supplied margin ensures that the cap screws will perfom their design function and still meet ASME code requirementsfor allowable stress. The following quantifies this margin.
2-1/2" diameter cap screws , A193 Gr.67 2-1/2"-8N-2A, (DI 4)
From Table 8.2.10 in Marks Handbook (reference 5). Minor diameter = 2.343 inch From page 7 of the design stress report for the pump (DI 4), the totai bolt area required, Am,= 62.31 inches2 WAPF6045.02 Ap6045.02 Original Page 1 of 4
W Technical evaluation No. TE 2001-0034 The bok root diameter required to supply the total bolt area required, considering all bolts degraded is:
MinDiameter = J4xAreq =J4x62*31 = 2.27inch.
nl Gbolts nl Gbolts The allowable corroded thickness (lost metal) on each bolt is M( 2.343-2.27) = 0.0365, (approx 1/32).
Given that no significant metal loss was noted on the threads and the inert atmosphere in the containment during operation, corrosion is not expected to occur at a significant rate during future operation.

To: DennisGirroir 5/1Y200 1 From: Ralph Connell Re: Report for TWE Inspections Performed for RF022 (Reference Xeport for IWE Inspections Performed for RF021 dated 12/02/1999)
INTRODUCTION:
The objective in the current period for this new ][WE inspection program was to gather as much information as we could for RF021 and RF022. During RF021 the goal was to perform as many inspections as possible within the acceptable window without causing any interference with other outage work activities. The remainder of the required first period examinations was performed either before or during RFOZZ.
After the ZWE examinations performed during RFO 21 the Program Procedure PP7024 was revised to incorporate lessons learned. Some revisions were made to the appendices regarding inspected components and inspection criteria. As a result some of the examinations originally listed for the 1 period were revised and are reflected in the completion schedule included in this report. All required VT-3 examinations were moved to the 3d period as required by the ASME Section M Code 1992/92A.
DISCUSSION:
The ASME Section XI Subsection IWE Code requires an examination of tbe coated Surfaces in order to determine the condition of the substrate. This examination of coated surfaces is for evidence of flaking, blistering, peeling, discoloration and other signs of distress of the underlying metal. The IWE examinations performed for RFO21 found only two areas of coating with signs of distress affecting the substrate. Those two areas were located at the drywell interior moisture barrier and the other was on the drywell surface at the X-5Gpenetration. Both of these were evaluated by Mechanical Design Engineering and dispositions provided via the IDR process. IWE examinations during RF022 identified two more areas. These were areas of pitting and corrosion in the vent header and corrosion in the interior of penetrations X-207A-H. Both of these were also evaluated by Mechanical Design Engineering and dispositions provided via the IDR process. At many areas of the containment there is peeling or discoloration. Both of these issues have been previously identified and accepted via the OP5250 inspections.
The Maintenance Department has been performing containment inspections for several years via OP5250 to evaluate the condition of the coatings on containment surfaces.
These inspections have compiled an excellent source of data documenting the conditions of the coatings and how these coatings are maintaining over time. The information provided &om these reports provides the basis for disposition of issues identified on the IWE reports such as coating peeling and blistering.
9 Several areas were identified as inaccessible during the RF021 and W022 IWE examination process. Those inaccessible areas are generally defined in PW024. More specific information is included with the data supplied in this report.
DETAILS:
TORUSSURFACE The surface fkom just below the catwalk on the exterior surface to the horizontal mid point of the torus was inspected prior to W 0 2 2 The remaining torus penetrations were examined prior to RF022 and during RF022.
Penetrations X-207A-H were identified as having corrosion exceeding the provided acceptance criteria. IDR 01-08 was written on this item. This was addressed by Design Engineering and a design wall thickness for these penetrations was provided. The X-207A-H penetrations are acceptable for continued use and the corrosion identified does not exceed the required design wall thickness.
Torus penetration (includes penetrations in the vent system) examinations were completed for the first period.
The interior surface of the vent header examination was completed during RlF022. There were areas of pitting and corrosion identified in the vent header that exceeded the provided acceptance criteria. IDR 01-07 was written to address the areas of pitting and corrosion. Design Engineering addressed this IDR and provided new acceptance criteria for the vent header corrosion identified. All areas are within the required design wall thickness provided by the Design Engineering resolution and are acceptable fur continued operation.
A U G m N m D m L SURFACES After review of the data gathered during RF021, a portion of the containment surface at the joint seal area was declared as augmented. This area was examined and documented during RFO22. No change was identified in the as inspected condition between RFO21 and RF022 in the augmented area.
Since the area of the augmented s d a c e was being prepared for seal installation and painting the opportunity to examine this region with white metal exposed and all corrosion removed presented itself The entire circumference in the moisture barrier area was examined and the areas of pitting and pit depths were identified. All pitting
identified by this examination were bounded by the 1999 evaluation, VYM 99/139, and are acceptable for continued operation of the drywell.
Forty-three (43) percent of the required first period drywell penetration examinations were completed during NO21 the remainder was examined either prior to or during RF022. Many of these penetrations depicted debris and peeling paint. The dddebris is not considered to be detrimental to the containment structure. All penetration cavities were dry with no visible indication of moisture. The peeling paint was similar to that identified in the maintenance reports and is not unusual for the age and environmental conditions experienced by the coating.
The diddebris identified in the drywell penetration cavities is a housekeeping issue only, not a containment integrity concern. All large debris located in the penetrations examined has been removed. The remaining debris consists of the accumulation of dirt, dust and paint chips over the life of the plant. The quantity of debris in the penetrations identified is not a containment integrity concern. Most diddebris was lying in the concrete sleeve and not in contact with the penetration. All penetrations examined (except for X-207A-H) were dry with no indication of water. The penetrations typically have a small access and pose difficulty cleaning. The dilemma from inside the drywell is the accessibility to the penetrations and the ALATU concerns.
The drywell moisture barrier at the concrete floor to steel interface on the 238 level was identified as failed during RF021 examination. During RFO 22 this seal was replaced.
To deal With the paint chipping and corrosion in the seal area and to accommodate the seal installation a six-inch wide band of paint was removed in the seal area for the full circumference of the drywell at the 238 level. The seal was reinstalled per minor mod
- 2000-010.The six-inch band was re-coated with non-qualified coating. The area of the seal and coating was examined after installation to document the as installed condition.
This seal acts as a gasket at the concrete to steel interface to prevent moisture from penetrating under the concrete and to prevent it fiom setting in the interface setting up localized corrosion. This area is an area that regularly gets flooded with water due to the activities that take place during outages in the dry well. This area also is an area that experiences wear and tear at a much higher rate than the rest of the containment due to its location. As a result of the location and outage activities this is an area that requires regular maintenance to keep the moisture barrier seal and the paint in the moisture barrier area intact and properly protecting the steel containment. The logistics of trying to place qualified coating at this location and then set up to regularly maintain it can be difficult as was seen during RFO22 not to mention very costly. I recommend that this moisture barrier area and the six-inch band of paint be declared a high maintenance area and designed as an area where unqualified coatings are approved and utilized. This will make the routine maintenance of this area much easier to perform resulting in better
maintenance of this area in the fbture. If this approach were approved, repainting with qualified coating would not be required only maintenance activity to maintain the integrity of the nonqualified paint and moisture barrier seal. This maintenance should become a routine PM.
PRESSURERETAlN1.G BOLllNG Bolting examinations for X-200A & B and V16-19-5G& H were completed during RF022 in the removed condition. Bolting examinations or Vl6-19-5A-F was examined in place. This completes the required first period IWE bolting examinations.
SUMMARY
An estimated 80% of MrE examinations are completed prior to or during RFO21. The remaining 20% were completed prior to or during RF022 to complete the first period examination requirements.
There were two new IDRs generated, per DP4027, for containment issues G n g W022. All of these issues were addressed by Mechanical Design Engineering prior to RF022 startup.
Please find attached to this report for reference the Summary of First Period TWE Examinations. This repod provides details for the fir&period examinations.

EVALUATION OF DATA PROWED BY VT-1, CONTAINMENT SURFACES (IWE)
DATA SHEETNO: 8045-01-019 During RFO 21 IWEexaminationsit was discoveredthat the Joint Seal at tbe concrete to steel interface on the 238' level of the containmenthad failed and there was evidence of corrosion in areas of the seal. As a malt a portion of the circamferenceof the seal interface area was declared as augmented. The joint seal itselfwas also s c w e d for replacement during RFO-22.
At the start of RFO-22 the examinersperformed the requiredVT-1examinationsof the augmented area at thejoint seal to determine if any changes had occurred chningthe last operating cycle. The results ofthat examination meal no changes identified in the augmented area After the VT-1 exminationswere complete the processbegan for the joint seal replacement. A band of paint was removed from the concrete loor up the steel c o n t a i n t approximately 6" wide for the fizll ciKnU33ference. The recessed area for the joint seal was also cleaned m preparationfor the new seat installation. At this point a VT-3 examinationswas performedwhich identified a band of pitting that Covered much of the 360-degreecircumference. A more detailed VT-1was ordered by the Responsrwe Engineer to detail this area prior to paidseal hstiUion.
Thisjoint seal area was identified as an issue in the early 1990's. (ER-99-1594deals with the issues fiom the 1990's resolution). lo 1993 the joint seal area was cleaoed and painted so as to form a paintjoint seal at the concrete to seal interface. The areas identified during the EO-21 examinations were areas thatwere experiencing evidence of Oormsion and paint loss in tbis painteajoint area. Some of the paint was still intact and providhg protection for the steel it was covering.
The new areas of pitting inthe area of the joint seal are as a result of the coatingremovalto white metal in this area. This area was not previously identified during RFO-21 because it was an old area of pitting that had been coveredby the 1993 coating and had not experienced any further degradation. As a result ofthe coatings being completely removed from thisjoint area,this VT-1 examhation was able to map this region without the impedance of any obstruction.
The areas of pitthg are isolated to the general area of the joint seal interface between the concrete and the stel. The pitting subsides as it move up or down out of the joint seal area. This was evident when a portion of the steel surface was exposed as a result of the removal ofa concrete chip. The imcler d a c e area exposed was approximately !3" wide.and 3" &ep in a crescent shape. The worst case pitting is isolated to aband in the joint seal area from approximately %" wide to approximately 1" wide and is described in the report as areas w i 6 general wastage and connected pining AU corrosionidentified within this report is bounded by evaluation VYM 99/139, Based on this evaluation ail areas are well withinthe required design base metal thicknesses and are for continued operation as is.
