Attachment Post-Outage 90-Day ISI Summary Report INTRODUCTION The Inservice Inspection Summary Report addresses examinations, repair/replacement activities, and Containment Inservice Inspections (CISI) performed between the end of the previous refuel outage, (L1 R09)

February 4, 2002, through the end of the current refuel outage (L1 R10). This refuel outage was the tenth for LaSalle County Station Unit 1. It started January 13, 2004 and ended February 12, 2004. This refuel outage was the first scheduled for the Third Inspection Period of the Second Inspection Interval, effective from November 23, 1994, through October 11, 2006, for LaSalle County Station Unit 1. Paragraph IWA-2430(e) of the American Society of Mechanical Engineers (ASME) Code Section Xl allows an Inspection Interval to be extended for a period of time equivalent to the duration of a continuous outage that exceeds six months. The Second Inservice Inspection Interval is divided into three successive inspection periods as determined by calendar years of plant service within the inspection interval.

Identified below are the period dates for the Second Inservice Inspection Interval as defined by Inspection Program B. In accordance with IWB-2412(b),

the Inspection Periods specified below may be decreased or extended by as much as one year to enable inspections to coincide with LaSalle County Station's refuel outages.

Unit 1, Period 1 (November 23, 1994 through October 11, 1999**)

Unit 1, Period 2 (October 12, 1999 through October 11, 2003)

Unit 1, Period 3 (October 12, 2003 through October 11, 2006)

    • This date reflects a 690-day extension allowed by IWA-2430(e) for LI F35.

Inservice Inspection (ISI) examinations, Augmented Inservice Inspection (AISI) examinations, Containment Inservice Inspections (CISI), and Preservice Inspections (PSI) were completed prior to and during the refuel outage as required by the Code of Federal Regulations, Technical Requirements Manual, ASME Boiler and Pressure Vessel Code, Section Xl, 1989/1998 Edition, and the applicable requirements of the Performance Demonstration Initiative (PDI).

Personnel from General Electric Nuclear Energy (GENE) Inspection Services and Exelon Nondestructive Examination Services group (NDES) performed the Non-Destructive Examinations (NDE), Magnetic Particle (MT), Liquid Dye Penetrant (PT), and manual and/or automated Ultrasonic (UT) techniques that were used during these inspections. All Intergranular Stress Corrosion Cracking (IGSCC) examinations were completed by personnel qualified for the detection and discrimination of IGSCC Cracking in accordance with the PDI.

NDES provided necessary resolution of technical problems, reviewed all ISI personnel qualifications, and all visual, surface, and volumetric examination results.

1

Visual examinations of reactor vessel internals, component supports, and piping pressure tests were performed by GENE personnel, Exelon Generation Company (EGC), LLC, employees of the LaSalle County Station Programs Engineering Group and NDES personnel. These individuals were appropriately certified as ASME Code Section Xl Visual Examiners to EGC's written practice. An underwater camera was used for the visual inspection of the reactor vessel internals. The camera was proven capable of resolving 0.001" and 0.0005" stainless steel wires while underwater and, in the same lighting conditions found during the actual inspection.

The services of an Authorized Nuclear Inservice Concrete Inspector (ANIC) was provided by Hartford Steam Boiler Inspection & Insurance Co. of Connecticut, 2443 Warrenville Road, Suite 500, Lisle, IL 60532.

Mr. Rocky W. White, ANIC, State of Illinois #1927, reviewed written Nondestructive Examination procedures, personnel qualifications, instrument and material certifications, ASME Code Section Xl examination results, Owner's Reports of Repair or Replacement (Form NIS-2), and the Owner's Data Report for Inservice Inspection (Form NIS-1).

II. SCOPE OF INSPECTIONS The ISI Summary Report is provided with tables that consolidate the extent and results of inspections performed between the end of the previous refuel outage (L1 R09), February 4, 2002, through the end of the current refuel outage (L1 R1 0). An explanation of all abbreviations used is in Attachment 3 of the Summary Report.

Table A provides a listing of all completed ASME Code Section Xl examinations for this refuel outage with the exception of component support examinations and pressure testing which are addressed separately. Table A is divided by ASME Code Category with a description of the item(s) examined, including the examination type(s), and the examination result(s).

Table B provides a listing of all (AISIs). These are not ASME Code Section Xl requirements, but are either additional examination area requirements, increased frequency requirements, or combinations of these which are requested by the Nuclear Regulatory Commission (NRC). Others have been deemed prudent in view of EGC and industry experience. Table B also gives a description of the item(s) examined as well as the examination type(s), and examination result(s). Table B includes the following categories:

2

TYPE 1A - These are ASME Code Section Xl Category B-F and B-J welds of the high energy line break exclusion regions, which are identified in the Safety Analysis Report (SAR) and examined as required by the NRC.

BWRVIP These examinations are of austenitic stainless steel piping for the detection of intergranular stress c6rrosion cracking (IGSCC).

REACTOR VESSEL INTERNALS AISI - These examinations include inspection of reactor internal components which have been required by the NRC such as core spray spargers and piping. These have been adopted by EGC through its commitment to the Boiling Water Reactor Vessel and Internals Project (BWRVIP). Other examinations, such as the steam dryer and steam separator, were deemed prudent from industry experience.

MISCELLANEOUS AISI -

Pursuant to LaSalle County Station's commitment to the NRC (reference letter), the AISI examinations included an augmented "End-Shot" UT examination of 100% (68 total) of the reactor pressure vessel closure studs.

The "End Shot" UT examination was completed using procedures, calibration standards, and personnel which met all applicable requirements of the 1989 Edition of ASME Code Section Xl, and the PDI.

Table C provides a listing of all completed ASME Code Section Xl Class 1 and 2 component support examinations for this outage. Table C gives the support number(s), examination type(s), and examination result(s). Table C is divided by ASME Code Class.

Table D provides a listing of pressure testing of ASME Code Section Xl Class 1 & 2 piping and components completed during the period between the Ll R09 and LI R10 refuel outages. As applicable, Code Case N-498-1, "Alternative Rules for 10-Year Hydrostatic Testing for Class 1, 2, and 3 Systems Section Xl, Division 1," is utilized during the Third Inspection Period. ASME Code Class 1 components and piping were examined using the VT-2 method during the system leakage test conducted at 1040 psig prior to reactor start-up, within the nominal operating pressure range of the reactor pressure vessel associated with 100% rated reactor power. Pressure testing will be ongoing throughout the remainder of the Third Inspection Period.

SUMMARY

OF RESULTS AND CORRECTIVE ACTIONS The ASME Code Section Xl ISI results obtained this refuel outage were compared with the Preservice and InService results. The following is a summary of the results and corrective actions taken.

1. ASME Code Section Xl Components Recordable indications were detected in ASME Code Section Xl components and other non-code components, during augmented examinations as discussed below or in the applicable Tables. All indications detected in ASME Code Section Xl components were evaluated against the applicable acceptance standards.

During the period of time covered by this report examinations and tests for the Unit 1 ASME Code Section Xl Class CC post tensioning system were performed. The following conditions have been identified and are being reported as required by 10 CFR 50.55(a):

  • During the examination of tendons, free water was identified in either the grease can or anchorage of the following tendons:

ounce Field End Shop End I Shop End I V010A TV012A I V013A

<1 ounce 1 ounce 1 2 ounces Field End Field End I Shop End IV026A I V028A I V044C X1

_12 ounces I 1 ounce I

Field End V058C 2 ounces The difference between the amount of sheating filler grease removed and the amount replaced exceeded 10% of the tendon net duct volume in the following tendons:

V001A 11.16% V002A 22.32%

V004A 16.57% V005A 29.76%

V006A 32.29% V009A 10.74%

V010A 13.65% V011A 15.22%

V014A 15.53% V018A 19.73%

V027A 14.71% V028A 15.45%

V030A 17.96% V005C 10.79%

Grease leakage was detected during examination of the containment surface near the field end anchorages of tendons V027A, V029A, V004B and V020B.

Examination of tendons identified degradation in the form of broken wires found on the following:

V002A 10 of 90 wires broken V003A 72 of 90 wires broken. This tendon was replaced.

V010A 4 of 90 wires broken V012A 7 of 90 wires broken. This tendon was replaced.

V013A 77 of 90 wires broken. This tendon was replaced.

V029A 58 of 90 wires broken. This tendon was replaced.

V014A 2 of 90 wires broken V030A 1 of 90 wires broken Five 'A" tendons and all thirty "B" tendons are inaccessible for examination during power operations. Degradation of the tendons is due to water-induced corrosion by failure of the water intrusion barriers and, aided by a loss of the corrosion protection medium (grease) in the top region of the accessible "A" tendons. The design of the inaccessible tendons incorporates a welded cover that prevents this type of degradation. To confirm this conclusion, a corrective action has been generated to inspect one inaccessible "A" and "B" tendon at the next scheduled refueling outage. This inspection is tracked by Action Tracking Item #157920, Assignment 33.

The results of the examinations and tests of the Unit 1 ASME Code Section Xl Class CC post tensioning system are in the process of being reviewed and evaluated. If required, additional information will be reported in the next subsequent Unit 1 ISI Summary Report.

2. Steam Dryer Based on LaSalle County Station experience, an augmented visual examination of the steam dryer is completed during each refuel outage. The steam dryer contains numerous indications that were recorded during previous examinations. Areas where historically indications were identified include the lifting eye bracket welds, upper dryer bank vertical welds, upper support ring, drain channel welds, and dryer bank panels. During the tenth refuel outage, specific inspections as recommended by SIL 644 Rev. 1 were performed and new indications were identified on the end panels for banks A, B, D, and on a guide rod follower bracket. The two indications detected on the end panels for banks A and D were evaluated as acceptable as-is with no repair required in accordance with EC #346971. The indication on the end panel for bank B and the guide rod follower bracket were stop drill repaired to prevent future crack propagation. Condition Reports #195996 (bank B) and #196072 (guide bracket) were generated to document these conditions. These examination results have been documented on the GENE examination data sheets.
3. Steam Separator Based on LaSalle County Station experience, an augmented visual examination of the steam separator is completed during each refuel outage.

During this examination in L1R10, no new indications were observed. A previous indication was noted on a gusset. This indication was previously identified and no Condition Report was generated. These examination results have been documented on the GENE examination data sheets.

4. Jet Pumps During the tenth refuel outage, an augmented UT examination was completed on 100% (20 total) of the jet pump hold down Beams. The UT technique used interrogated the bolt hole area (BWRVIP-41 location BB-1), the beam ears (BWRVIP-41 location BB-2) and the beam transition area designated BB-3.

The examination detected one potentially detrimental indication in the bolt hole area of the beam on jet pump 15. Condition Report #196552 was generated to document this indication. This jet pump beam was replaced in LI R10 with a new design, weldless, rachet-lock beam. After replacement, visual examination revealed a gap between one adjusting screw and the respective inlet mixer. A permanent repair wedge was installed to eliminate the gap. The beam replacement and wedge installation was completed under Work Order

  1. 554306.

During Ll R10, augmented inspection of jet pump main wedges was performed. The VT-1 inspections revealed wear on 10 of the 20 wedges. The wedge on jet pump 19, the rod was worn and the upper nut on the rod had worn into the wedge bracket. As a result, all of the auxiliary wedges were inspected by VT-1. No additional auxiliary wedge wear was detected, but the ratchet teeth on two of the auxiliary wedges were not fully engaged.

Inspections were performed to determine if gaps existed between the jet pump inlet mixers and the set screws. Gaps were identified on nine jet pumps.

These inspection results were documented in Condition Report #197310. For sample expansion riser brace RS-8 and RS-9 welds were inspected by EVT-1.

Indications were noted on the RS-9 welds on both the jet pump 5 and 6 sides of the jet pump 5/6 riser brace. One indication was also noted on the jet pump 9 side of the jet pump 9/10 riser brace. Inspection results were documented in Condition Report #199081. Flaws at this location have been observed at other Boiling Water Reactors.

The main wedge wear and the lack of engagement of the ratchet teeth were accepted as-is under EC #347046. Due to the wedge rod and nut wear on jet pump 19, the inlet mixer was removed and replaced with a spare as authorized by EC #347046 and EC #347052. An auxiliary wedge was installed at locations where there was a gap between the jet pump inlet mixer and a set screw. Twelve auxiliary wedges were installed under WO #554306. The three riser brace indications were accepted as-is for one cycle under design analysis L-003012. This analysis was performed in accordance with the guidance provided in BWRVIP-03 and BWRVIP-41.

When the inlet mixer for jet pump 19 was removed, examinations of areas made accessible below the core plate were performed. Examinations included accessible portions of bottom head cladding in vicinity of jet pump 19, surfaces/welds on CRD stub tubes and guide tubes, shroud to RPV weld H-9 located below the shroud support plate, jet pump adapter welds on 18 and 20, and a general overview of the bottom head. No recordable indications were noted.

A root cause evaluation was performed and determined that one of the causes of the jet pump wedge wear, was operation with high slip joint differential pressure (low M-ratio) that puts the jet pumps under hydraulic conditions, and contribute to abnormal inlet mixer vibration and associated wedge wear. As a result of the root cause, a clamp was installed on all twenty jet pumps at the slip joint. The clamps were installed under WO #659181.

5. Core Spray Piping During the tenth refuel outage, an augmented UT examination was completed on accessible core spray piping welds internal to the reactor vessel. The examination detected five relevant indications; one on weld BP4a and two on welds DP6 and DP5. Condition Report #195988 was generated to document these indications. The indications were accepted as-is for one cycle under design analysis L-003008.

6. ASME Code Section Xl Piping & Component Support Examinations Piping and component supports were inspected (52 total) during this refuel outage. These were distributed between ASME Code Section Xl Class 1 and 21D+ supports as follows:
  • ASME Code Class 1 - 34 supports.
  • ASME Code Class 2/D+ - 18 supports.

Two rejectable indications were detected during examinations.

FW02-1158X had a loose nut on the pipe clamp load bolt. Condition Report

  1. 195554 was initiated to disposition the indication. The loose nut condition was corrected under Work Order #656884. Support FW02-1158X was re-examined and found to be acceptable.

RH04-1505C had a loose nut on the hanger rod connection to the pipe clamp load bolt. Condition Report #195900 was initiated to disposition the indication.

The loose nut condition was corrected under Work Order #657112. Support RH02-1505C was re-examined and found to be acceptable.

As required by ASME Section Xl Code Case N-491-1, "Alternative Rules for Examination of Class 1, 2, 3, and MC Components Supports of Light-Water Cooled Power Plants Section Xl, Division 1," sample expansion examinations were completed for the two rejectable indications. No further detrimental indications were detected.
