In late December, 2001, Southern California Edison (SCE) recognized that the Owner's Report of Inservice Inspections (ASME Section XI Reports) for the cycle 11 outages for Units 2 and 3 were incomplete. Due to an administrative oversight, these reports did not include replacement of the Low Temperature Overpressure Protection valves for their respective unit.

While investigating the cause of these omissions, SCE discovered that the Unit 2 cycle 10 report had also omitted one applicable component replacement. This omission was caused by individual personal error.

SUMMARY

REPORT UNIT 2 10 OF 17 ABSTRACT OF RESULTS OF EXAMINATIONS & TESTS The inservice and preservice examinations conducted at SONGS 2 were performed between 9/16/97 and 2/26/99. These examinations were performed to fulfill the requirements of 10CFR50.55a(g)(4) and IWA-1400, Owner's Responsibilities of ASME Code Section XI, 1989 Edition, No Addenda.

The number of components and supports for Class 1 and 2 selected for examination was based on the ISI Program Plan Doc. # 90063, Rev. 4 employing Inspection Program Plan B of the ASME Code Section XI, 1989 Edition, No Addenda. This code edition also employs the Mandatory Appendix VII which requires qualification of NDE personnel for UT examination. All the UT Level-I, UT Level-Il and Level-III examination personnel performed the UT examinations were qualified per Appendix VII. For Class CC and MC components governing Code Edition Addenda is 1992 Edition and 1992 Addenda as mandated by NRC final rule.

All the pressure retaining components of ASME Class 1, 2 and 3 System pressure test were performed per the requirement of ASME Code Section XI 1989 Edition, No Addenda.

IN Class 1 and 2 components 209 welds/components were examined for volumetric examination, 239 for surface, and a total of 91 for a combined VT-I and VT-3 visual examination.

All the NDE examinations were found Code acceptable.

The Fifteenth year Containment Structure tendon surveillance was conducted between October 1997 and November 1997. The unit-2 containment structure post-tensioning system has met the requirements specified per Technical Specifications, Licensee Controlled Specifications, and per the NRC final rule that amended 10CFR50.55a, Codes and Standards, on August 8, 1996, and Subsection IWL of Section XI, ASME Code.

ATTACHMENT SPECIAL REPORT - INSERVICE INSPECTION OF STEAM GENERATOR TUBES

SPECIAL REPORT - INSERVICE INSPECTION OF STEAM GENERATOR TUBES Regulatory Reporting Requirements Reporting Requirement 5.7.2.c of Appendix A, Technical Specification to Facility Operating License NPF-10, requires the number of tubes plugged and tubes sleeved in each steam generator to be reported to the Nuclear Regulatory Commission within 15 days following completion of the inspection.

Reporting Requirement 5.7.2.c of Appendix A, Technical Specification to Facility Operating License NPF-10, requires the results of steam generator tube inspections which fall into Category C-3 to be reported to the Nuclear Regulatory Commission prior to resumption of plant operation.

Reporting Requirement 5.7.2.c of Appendix A, Technical Specification to Facility Operating License NPF-10, requires the complete results of steam generatortube inspections to be reporte'd to the Nuclear Regulatory Commission within 12 months following completion of the inspection.

Planned Inspection Scope Table 1 summarizes the planned inspection program. Also, when indications by the bobbin probe were non-quantifiable or distorted, the inspection program included inspection with the Plus-Point Probe. Table 4 provides the list of Nondestructive Examination (NDE) techniques utilized for each degradation mechanism.

Inspection Scope Expansion Table 2 summarizes significant inspection program scope expansion in response to inspection results. The following explanatory details are provided for these expansions.

It should be noted that only one apparently small axial indication was detected in the sludge pile region near the top of the cold leg tubesheet. This was the first time that this specific tube location had been examined with a rotating probe, so the time that this indication may have been present cannot be ascertained. It should be noted that an expansion with the plus point probe to 100%

of these locations in both steam generators did not detect further indications of this type. In the course of this first-time 100% inspection of this location with the plus point probe, 5 volumetric indications associated with eddy current indications of foreign object presence were detected.

These volumetric indications would not have been detectable in previous bobbin probe inspections, due to their proximity to the top-of-tubesheet.

The volumetric indications, and associated tubes with eddy current indications of foreign objects were removed from service by installation of a "stabilizer" spanning the affected region, and plugging. Associated foreign objects were not visible during visual examination of the outer periphery of the tube bundle, and retrieval efforts within the tubing bundle were deemed not practical.

An axial crack indication at a dented eggcrate tube support was found within a defined "buffer zone" (the uppermost hot leg eggcrate tube support) for a "critical area for inspection." In response to this, the critical area was re-defined to include this buffer zone. A new buffer zone was defined as all dented tube supports at the next highest elevation (the hot leg diagonal bar support).

SPECIAL REPORT - INSERVICE INSPECTION OF STEAM GENERATOR TUBES ATTACHMENT Page 2 of 29 Results This report satisfies the listed regulatory reporting requirements.

The contents of this report are prepared using the guidance contained in NEI 97-06, Rev. 0, "Steam Generator Program Guidelines." The NEI guidance is an initiative to unify the industry approach towards steam generatorissues and strengthen, where necessary, the steam generator program. In accordance with the suggested NEI guidance, the following five (5) report contents are included within this report.

(1) Scope of inspections performed; (2) Active Degradation Mechanisms found; (3) Nondestructive Examination (NDE) techniques utilized for each degradation mechanism; (4) Number of tubes plugged or repaired during the inspection outage for each active degradation mechanism. Repair methods utilized and the number of tubes repaired by each repair method; and (5) Total number and percentage of tubes plugged and/or repaired to date and the effective plugging percentage in each steam generator.

Although this report satisfies the Technical Specification reporting requirements, an update will provided to include the following additional three NEI suggested content items:

(6) Description of the tube integrity assessment; (7) Description of corrective actions implemented, if any; (8) Evaluation of circumstances if condition monitoring results exceeded the previous cycle operational assessment.

Table 3 summarizes significant inspection results, and active degradation mechanisms found.

Each tube is only counted once in this listing, although it may also have an eddy current indication of a type below the point in the listing where it appears. The Appendices provide the complete results of the steam generator tubing inservice inspection.

Table 5 summarizes in-situ pressure and leak testing results. This particular testing demonstrated the structural and leakage (i.e., there was no leakage) integrity of the tested tubes.

Preliminary review of eddy current testing results and in-situ pressure and leak testing results indicates that performance criteria in the NEI guidance (structural integrity and accident-induced leakage) were met during operation prior to this inspection.

SPECIAL REPORT - INSERVICE INSPECTION OF STEAM GENERATOR TUBES ATTACHMENT Page 3 of 29 Repair of Tubes Table 3 lists the number of tubes repaired (removed from service by plugging, or repaired by sleeving) for each steam generator. Table 6 provides an itemized listing of the tubes plugged in steam generator E-088 along with the corresponding Table 3 category specifying the indication orientation/location. Table 7 provides an itemized listing of the tubes sleeved in steam generator E-088 along with the corresponding Table 3 category specifying the indication orientation/location.

Table 8 provides an itemized listing of the tubes plugged in steam generator E-089 along with the corresponding Table 3 category specifying the indication orientation/location. Table 9 provides an itemized listing of the tubes sleeved in steam generator E-089 along with the corresponding Table 3 category specifying the indication orientation/location.

Repair Methods, Number of Tubes Repaired and Effective Plugging Percentage All tube plugging was performed using the design, materials, and installation methods of FRAMATOME Technologies, Inc. (FTI). A "weld" method was used for two tube plugs, and a "roll" method was used for all other tube plugs. Seventeen tubes were "stabilized" in the vicinity of the top of the tubesheet using the design, materials, and installation methods of FTI.

All tube sleeving was performed using the welded sleeve design, materials, and installation methods of ABB Combustion Engineering. This repair method is specifically addressed in the San Onofre Unit 2 and 3 Technical Specifications.

Fifty-two tubes were plugged, and 85 tubes were sleeved in Steam Generator E-088 during the Cycle 10 refueling outage. A total of 688 tubes have been plugged and 85 tubes have been sleeved to date. The design number of tubes is 9350 tubes and the sleeve to plug equivalency ratio is 38 sleeves per plug. The effective plugging percentage for E-088 is 7.4%.

50 tubes were plugged, and 52 tubes were sleeved in Steam Generator E-089 during the Cycle 10 refueling outage. A total of 708 tubes have been plugged and 52 tubes have been sleeved to date. The design number of tubes is 9350 tubes and the sleeve to plug equivalency ratio is 38 sleeves per plug. The effective plugging percentage for E-089 is 7.6%.

Causes And Corrective Actions The degradation detected during this inspection remained within the Technical Specification category "C-3". There is no significant update since the previous report of causes and corrective actions for "C-3" category results. Thus, this portion of the previous report is provided below.

Actions have been taken to improve the secondary side chemistry environment for steam generator tubing in both Unit 2 steam generators. These actions have been reviewed by a panel of industry experts for application at SONGS. The expert panel concurs with these measures.

The actions include:

SPECIAL REPORT - INSERVICE INSPECTION OF STEAM GENERATOR TUBES ATTACHMENT Page 4 of 29

1. Chemical cleaning of the entire tube bundle (full bundle) performed during the last refueling outage.

2. Addition of an inhibitor (titanium dioxide) for IGA/SCC immediately after the chemical cleaning for maximum crevice penetration potential.

3. Use of Ethanolamine (ETA) for pH control of the secondary fluids.

4. Boric acid addition in the secondary side to help reduce denting of the tube supports and stress corrosion cracking of tubing.

In addition, SCE has initiated a plan to reduce the reactor coolant temperature at the steam generator inlet (F-hot) by about 130 F. SCE expects this will reduce stress corrosion cracking of the tubing initiating from the inside diameter of the tubing. The first phase of this plan, a reduction of about 40 F, was completed in January 1998.

Supervisor or De nee Date Note 1: AF Min Path Leakage Rate is outage related. Failure to meet limit of less than or equal to 0.6 La may be reportable.

Note 2: AL Max Path Leakage Rate is outage related. Must be less than 0.6 La prior to Mode 4 entry.

Note 3: AL Min Path Leakage Rate is applicable when containment intergrity is required. Must be less than 0.6 La.

Failure to meet this limit may result in plant shutdown.

COMMENTS This is to document that the total containment LLRT leakage is less than 0.6 La for Mode 4 entry coming out of U2C1 0 outage.

U2C9 = Cycle 9 outage: M2C9 = Cycle 9 midcyc!e outage; U2C10 = Cycle 10 outage.

AR 990201060 documented the As-Left (AL) LLRT result exceeding the admin limit for S21415MU236 for Pen 11.

1.0 INTRODUCTION

This report describes the results of the fifteenth year "tendon surveillance at San Onofre Nuclear Generating Station (SONGS)

Unit 2 containment structure.

The work was conducted between October 1997 and November 1997.

The surveillance was performed by the ISI Group of Site Technical Services with assistance from Nuclear Construction. The surveillance was performed based on the requirements found in procedure S023-XVII-3.8, Revision 5.

The surveillance purpose is to determine if the post tensioning system is functioning within the specified design requirements per Technical Specification 3.6.1 and Licensee Controlled Specification (LCS) 3.6.100, to identify unacceptable conditions which may exist, and to recommend corrective action where unacceptable conditions are found.

This report provides the Civil Engineering evaluation of the Unit 2 containment structure fifteenth year tendon surveillance.

The overall condition of the containment structure post tensioning system is evaluated from the obtained data and compared to previous surveillance data.

Major Items of work included:

SA.

Visual inspection of the concrete surrounding the bearing plates of all horizontal surveillance tendons listed in Table I for the applicable surveillance year.

B.

Inspection of the tendon anchor assemblies for deleterious conditions such as corrosion, cracks, missing wires, and inadequate grease coverage.

C.

Visual rinsoection of anchor head shims. where installed, for adequate grease coverage.

D.

Visual inspection after cleaning to determine corrosion levels and indications of excessive stress.

E.

Visual inspection of bearing plate for cracking, excessive deformation, and movement into the anchorage.

F.

Visual inspection of all tendon end caps to detect any grease leakage, cap deformation, missing petcocks or degradati on.

G.

Visual and laboratory examination of sheathing filler.

2.0 RESULTS / CONCLUSIONS A.

RESULTS

1.

The visual inspection records in Appendix A for the concrete surrounding the anchorages of the horizontal tendons did not reveal cracks of significant size.

There is no abnormal degradation of the containment structure concrete which would adversely affect the Post-Tensioning system.

2.

The visual inspection results of the tendon anchorages from Appendix A are summarized in Table 1:

1. All tendon components were adequately covered (100%)

with grease and no free water was observed.

2.

NCR 971001038 addresses tendon #13 on the east side of buttress 1, where three slipped tendon strands were found.

Two strands were slipped uniformly while the third strand had differential slippage with one wire full length and the remaining 6 wires with slippage varying from

)

approximately 7 to 9 inches.

In addition, approximately 6 wedges were unevenly set with a differential of about 1/4". One of the wedge pieces for a strand that slipped uniformly was also loose.

An operability assessment was performed and determined that the 52 remaining strands are sufficient for the tendon to perform its design function. The design of the cylindrical hoop tendon is for a prestress of 780 k/ft (Ref:

Vendor calc. S023-204-3-8) which provides an allowable concrete stress of 5400 psi (hoop).

52/55 x 5400

= 5105 psi would be a conservative estimate of the remaining prestress after the loss of the three strands out of the 55 strands total for the tendon. Since the maximum hoop stress in the wall is 2921 psi (Fig.

7-1 of calc. C-257-1.04) and is still less than 5105 psi, the containment structural integrity is adequate for its design loads.

15th Year Containment Structure Tendon Surveillance Report SONGS 2 3-

3.

There were no missing tendon strands found and "all anchorage steel components were observed to be free of cracks and deformations.

4.

Minor corrosion on a few of the anchor heads inspected were consistent with previous inspections.

5.

No corrosion was observed on the shims, bearing plates, tendon strands or wedges inspected.

6.

None of the inspections disclosed conditions that would have an adverse effect on the performance of the Post-Tensioning system.

3.

Samples of the casing filler (grease) for each insoected tendon were taken to Truesdail Laboratories, in Tustin, CA, on November 6, 1997 for testing.

All twelve grease samples tested were within the acceptance criteria.

The laboratory results of the grease are summarized in Table 3.

No unacceptable levels of nitrate, chloride, sulfide, or water were found. The Total Base Number for all the samples, as determined by the method shown in Attachment 10 of procedure S023-XVII-3.8, exceeded 35 as required.

4.

All tendon end-caps were properly installed with new 0-rings and end anchorages regreased.

All voic ratios were determined to be less than 5% of the net duct volume (Technical Specification limi:).

The "Containment Structural Integrity Surveillance" procedure (S023-XVII-3.8, Rev.

5)

formula, as documented in Section 7.4.2, was used to calculate the void ratios. The void ratios reported in the data sheets are summarized in Table 2.

B.

CONCLUSIONS The Unit 2 containment structure post-tensioning system is within the requirements specified per Technical Specification 3.6.1 and Licensee Controlled Specification (LCS) 3.6.100.

There is no evidence of abnormal degradation and no reportable conditions were 15th Year Containment Structure Tendon Surveillance Report SONGS 2 found except for NCR 971001038 as noted in Section A above.

3.0 METHODOLOGY /

SUMMARY

OF DATA This surveillance was performed in accordance with Station Procedure S023-XVII-3.8, Revision 5, "Containment Structural Integrity Surveillance" (Reference 4.2).

The work was performed by Site Technical Services and witnessed by SCE Quality Control.

The surveillance data for each tendon is included in Appendix A.

Material test results for the grease chemical analysis tests are included in Appendix B.

3.1 CONCRETE INSPECTION The concrete surface around the tendon anchorage is visually inspected for any signs of containment degradation and reported in the data sheets in Appendix A.

Inspection of the concrete adjacent to vertical tendon end anchorages is not possible and has been exempted in the surveillance procedure. The tendon gallery steel panels completely cover the concrete surface around the anchorages.

Several cracks (0.010" or less in width) were discovered in the concrete around the bearing plates for horizontal tendons 50 and 114. These cracks were found to be acceptable and were of the type emanating from the corners of the bearing plates..This type of crack :s caused by shrinkage of the concrete around the bearing oiates.

The steel does not snrink and causes the concrete to form small diagonal cracks at the corners.

This is a typical condition and considered normal.

Also, see Appendix III of C-501-01.01, "Maintenance Rule - Containment Unit 2 Inspection Report" for additional acceptance criteria for cracks in concrete.

In addition, numerous bugholes with diameters varying from 1/16" to 1/8" were found in the concrete surfaces adjacent to several baseplates.

Some minor concrete surface spalling was also observed in the same vicinity. These conditions are typical and considered normal for such concrete and do not impact ;he structural integrity of the containment structure.

15th Year Containment Structure Tendon Surveillance Report SONGS 2 3.2 ANCHORAGE COMPONENT INSPECTION The anchorage components are visually inspected for signs of corrosion, cracking or fatigue which would indicate abnormal degradation.

None of the anchorage components exhibited any sign of cracking, embrittlement, deformation, or other physical damage.

All inspected strands, shims, bearing plates and wedges were found to be free of visible corrosion or oxidation.

Several anchor heads were found to have some visible oxidation without any pitting. This type of minor oxidation observed is consistent with previous inspections and the observed corrosion does not indicate anchor head degradation.

The grease adjacent to these anchorages showed no signs of water intrusion or discoloration.

3.3 VISUAL AND LABORATORY INSPECTION OF SHEATHING FILLER The sheathing filler material (grease) is visually inspected for signs of water and chemically analyzed to verify that there are no corrosive conditions present in the tendon.

The visual inspection of filler grease disclosed that all anchorage components had adequate grease coverage with the exception of the top half of anchor head 12 for tendon 12-140.

AR 971001469 was written and the condition was dispositioned as acceptable. There was no sign of contamination of the filler grease.

No free water was found near the tendon end anchorage or in the sheathing filler. Also, there was no corrosion on the anchorage components.

Laboratory analysis of the sheathing filler samples contained in Appenaix B, disclosed that.he grease was free of unacceptaole nitrate, chloride, suifide, or water contamination.

3.4 RESEALING OF TENDONS All tendons were adequately greased with the specified sheathing filler (grease).

New 0-ring gaskets were placed on all tendon end caps removed for inspection and refilled with grease.

Tendon end caps were visually inspected for leakage.

None of trhe scheduled surveillance tendons were found to have any leaks.

I 15th Year Containment Structure Tendon Surveillance Report SONGS 2 3.7 NON-CONFORMANCE REPORTS

)*

There was one NCR written against the tendon surveillance on Unit 2.

It is included in Appendix C and the NCR has been properly dispositioned and no reportable conditions exist. The NCR documented three slipped strands for tendon #13 and its disposition and conclusions are discussed in greater detail in Section 2.A.2.2 of this report. The cause for the slipped tendon strands has not been determined but a root cause assessment will be performed for the NCR.

S023-XVII-3.8. 1 IS] Report Page 3 1.0 Introduction The Containment concrete was inspected as mandated by the NRC's final rule that amended 10CFR 50.55a, Codes and Standards, on August 8, 1996. The final rule required the examination of Class MC and Class CC components of ASME Section XI Code and was effective September 9, 1996.

The Containment concrete is considered a Class CC component for the inservice inspection requirements. The Class MC components and metallic liners of Class CC components of the containment will be examined in the ISI program per procedure S023 XVU-3.4 (Reference 5.6). Inspection of the tendons was performed independently of this inspection and was done per procedure S023-XVII-3.8, "Containment Structural Integrity Surveillance."

This report describes and documents the results of the visual examination of the Unit 2 containment concrete shell at San Onofre Nuclear Generating Station. The examination was performed between June and July 1998.

The objective of the examination is to ensure the containment structure will meet its design basis to maintain structural integrity during design conditions.

S023-XVII-3.8.1 ISI Report Page 4 2.0 Inspection Implementation 2.1 Procedure The examination of the Containment concrete was performed in accordance with procedure S023-XVII-3.8.1, "Visual Examination of Containment Concrete Surfaces," Revision 0 (Reference 5. 1).

2.2 Personnel Qualification The qualification requirements are specified in procedure SO23-XrVI1-3.8.1. The examination was performed by Torrey Yee of the Nuclear Engineering Design Organization, who is the Containment System Design Engineer or Responsible Engineer. Mr. Yee is a registered Civil Engineer in the State of California and is certified as an ASME Level II inspector for VT-1 C and VT-3C per procedure S0123-XalI-2.17.

2.3 Method The containment concrete shell is Examination Category L-A, Item L L.10, L1. 11 and Ll.12 per ASME Section XI, Subsection IWL (Reference 5.2).

Direct visual examinations were performed when possible without the need for scaffolding and mechanical lifts. Otherwise, accessible surface areas were visually examined remotely using binoculars or a spotting scope having the resolution and clarity to attain the acuity requirements for the VT-I C and VT-3SC inspections.

The tools used for the visual examination included a 9X (power) Nikon binoculars, a 77mm Bausch & Lomb spotting scope with a 20-60X zoom eyepiece, a IOX crack comparator that is able to read from 0.001 to 0.120 inch, 6 inch scale, 25 ft.

tape measure, a light meter and portable light sources that are able to provide a minimum 50 foot candle illumination. Maximum examination distance was checked with a card that contained 0.044 inch and 0.105 inch high lower case letters in accordance with ASME Section XI, Subsections IWA and IML.

S023-XVII-3.8.1 ISI Report Page 5 Concrete conditions were VT-3C visually examined for evidence of damage or degradation using the guidance of ACI 201.1R-92 (Reference 5.4). The findings of the examination are noted on inspection data sheets that have been included in Appendix A of this report. The following conditions were to be noted as suspect conditions and require a VT-IC visual examination:

1.

Crack widths between 0.013 in. to 0.040 in. shall be noted as existing. Crack widths greater than 0.040 in. shall be recorded with the measured length, location and frequency.

2.

Leaching, exudation, stalactites, and laitance.

3.

Medium and severe scaling.

4.

Spalts greater than I in. In any dimension. Popouts and bugholes greater than I in. in diameter.

5.

Concrete deterioration by abrasion damage, blistering, cavitation damage, corrosion, impact and delamination.

6.

Rust stains from reinforcement corrosion and efflorescence.

7.

Exposed reinforcement.

The acceptance criteria as provided in Procedure S023-XVII-3.8.1 (Reference 5.1) follows:

The condition of the concrete surface is acceptable if the Responsible Engineer determines that there is no evidence of damage or degradation sufficient to warrant further evaluation or repair. The following conditions are acceptable and do not need an evaluation:

1.

Crack widths.013 in. or less.

2.

Light scaling

3.

Spalls, popouts and bugholes 1 in. in diameter or less.

S023-XVII-3.8.1 ISI Report Page 6 3.0 Inspection Results and Evaluations 3.1 General Condition The general condition of the containment concrete shell is good and most areas met the acceptance criteria of procedure S023-XVII-3.8. 1. Conditions that were within the acceptance criteria included concrete cracks, light scaling, small bugholes and spalls. Concrete cracks were found throughout the containment surfaces and their crack widths were less than.013 in. Light scaling, small bugholes and spalled concrete were also observed in various locations and appeared to have existed since the time of original construction. The minor and superficial defects do not adversely affect the structural integrity of the Containment. The visual examination was performed between June and July 1998.

3.2 Suspect Conditions As required by the inspection procedure, suspect conditions were recorded and a VT-IC visual examination was performed. The majority of the reported suspect conditions involved bugholes greater than I inch in diameter. Some very localized spalling were found at the containment penetrations. The spalls were usually at the edges of the penetrations and appeared to have occurred during original construction. Bugholes greater than 1 in. in diameter were evident in scattered locations on the walls and with greater frequency on the dome between Elevation 112 feet to about Elevation 174 feet. The bugholes occurred during the placement of concrete in constructing the containment. The bugholes do not show any signs of distress, exposed reinforcement, or concrete degradation. They were less than 1.5 in. deep and do not affect the concrete wall strength because the outer concrete surface of the containment will be under tension during design basis events. The concrete cover on the containment is a minimum of 2 to 2-1/4 inches so there were no exposed reinforcement bars found on the spalls and voids.

The containment is considered a massive concrete structure because of the nominally 4 feet thick walls and heavy steel reinforcing. The voids do not affect containment concrete strength because in reinforced concrete design, the concrete cover is not considered when calculating the concrete element's tensile strength.

The reinforcing steel and post-tensioned tendons withstand the tensile stresses and govern the capacity to allow for a ductile design. Also, there is sufficient safety margin in the concrete to account for minor defects in the concrete surface. When the concrete cross-section is in compression, the maximum design concrete stress is calculated to be 3626 psi which is less than the concrete allowable of 5400 psi

S023-XVII-3.8.1 ISI Report Page 7 (Reference 5.5). If the concrete thickness was uniformly reduced by 1.5 inches, the concrete stress would increase about 3 percent and still be below the allowable stress (3735 psi < 5400 psi). Therefore, the spalls and voids will not affect the structural integrity of the concrete containment.

The suspect conditions were also documented on AR 980800999 as required by the inspection procedure. Since the structural integrity of the containment is not adversely affected, the containment is operable and will function as designed. No corrective actions were required.

Since the tendon gallery is not an essential appurtenance for containment integrity, the concrete walls and floor are not subject to the TWL examination. The tendon gallery primarily provides access to the vertical tendons and the following description of its condition is for information. Water leakage in the tendon gallery is occurring at the concrete construction joint at the top of the tendon gallery wall and the bottom of the basemat. The water leakage condition has been noted in the past and was reported in the maintenance rule inspection of the containment in 1997. The leakage is mostly evident during the rainy season. Some leaching has occurred, but there is no other indications of concrete degradation, such as cracking and spalling. There is corrosion of the ledger angle at the top of the tendon gallery wall and surface corrosion on the ceiling plates. While the tendon gallery condition is currently acceptable, the area will be monitored in the maintenance rule program for changes in condition.

3.3 Summary of Data Sheets The data sheets of the examination are provided in Appendix A of this report. The "Containment Concrete Visual Examination Summary Sheets" show that all areas of the containment concrete shell were inspected with the exception of the noted inaccessible areas. The "Concrete Surface Visual Examination Report Forms" were utilized to record the suspect conditions that are discussed in Section 3.2 above. The majority of the examination report forms were prepared to record the presence of bugholes that have existed since the containment was built.

S023-XVII-3.8.1 ISI Report Page 8 3.4 Inaccessible Areas The inaccessible areas include the following areas:

1.

Plant vent stack ducts cover Buttress 2 surface.

2.

Walls from Elev. 15' to 30' are below grade and embedded in the soil, except the tendon access shafts and the Penetration Area.

3.

Basemat is embedded in the soil

4.

Tendon Gallery ceiling (bottom of basemat) is covered by steel plates that were used as the concrete forms.

5.

Expansion joints between adjacent structures are covered with material for fire barriers.

6.

Portions adjacent to MSIV and penetration area that abut the containment shell.

No conditions were found in accessible areas that indicate the potential for degradation of the inaccessible areas. While cracks, bugholes and spalls could also exist in the inaccessible areas, the extent of the defects does not affect structural integrity as stated in Section 3.2. Also, the concrete cover of the containment is primarily relied on to provide corrosion protection of the reinforcement bars. No evidence of corrosion of reinforcement bars was found in accessible areas during the visual examination.

The containment basemat is deep enough that the buried exterior surfaces may be exposed to groundwater. Groundwater samples at the site show very low concentrations of elements, such as chlorides and sulfur, that could cause concrete and reinforcement degradation.

Therefore, the condition of the inaccessible areas is deemed to be acceptable because there is no signs of significant concrete degradation in accessible areas and the inaccessible areas are not exposed to a harsh environment.

S023-XVII-3.8.1 ISI Report Page 9 4.0 Summary and Conclusion The containment concrete shell was examined as required by procedure S023-XVII-3.8.1 which was written to comply with the NRC Final Rule. The visual examination did not find any significant defects in the containment concrete. The containment concrete surface exhibited small cracks, spalls and bugholes throughout the structure. Some areas with suspect conditions (larger bugholes and spalls) were also observed and reported in AR 980800999. The suspect conditions were determined to have existed since original construction and do not adversely affect the structural integrity of the containment.

Inaccessible areas were deemed to be acceptable due to the insignificance of defects found in accessible areas and the inaccessible areas are not exposed to a harsh environment.

Therefore, the containment structure's concrete shell is acceptable and will be able to withstand its design loads.
