Section I

Introduction



The fifteenth lnservice Inspection (ISi) of Dresden Unit 2 was performed during the Spring Refueling Outage, which lasted from March 7, 1998 to April 17, 1998. This was the first and only scheduled outage of the second inspection period of the unit's 3rd 10-year ISi Inspection Interval which commenced on March 1, 1992. The second period commenc·ed on January 20, 1997 and is currently scheduled to end on January 19, 2000. In addition to examinations performed during D2R15, this report also contains inspections which were not included in the previous Unit 2 Summary Report (dated July 23, 1996) as well as examinations completed prior to D2R15.

General Electric was contracted to perform the non-destructive examinations and reactor vessel visual examinations during the refuel outage. General Electric and ComEd personnel performed the remaining visual examinations. Personnel from ComEd's System Materials Analysis Department (SMAD) participated in performing inspections, technical advice, reviewing examination results, and evaluating indications.

The Authorized Nuclear lnservice Inspector's (ANll) services were provided by Hartford Steam Boiler Inspection and Insurance Company (HSB). The ANll reviewed procedures, personnel qualifications, instrument and material certifications, and examination results.

All examinations were performed in accordance with the Unit 2 Technical Specifications, the ASME Boiler and Pressure Vessel Code, Section XI, 1989 Edition and 1992 Edition with 1992 Addenda, Generic Letter 88-01, NUREG 0619, BWRVIP-07, BWRVIP-18, and BWRVIP-41.

A list of abbreviations used throughout this report can be found in Section IV of this report.

Spring 1998 lnservice Inspection Unit 2; National Board No. N-137 Commercial Service Date: 6-9-72

Summary of Reactor Vessel Interior Examinations Attachment A

During the D2R15 refueling outage, comprehensive visual and ultrasonic examinations of reactor vessel internal components were conducted to ensure continued integrity. These examinations serve to meet the requirements of Section XI of the ASME Code, anticipated inspection requirements of various BWRVIP (Boiling Water Reactor Vessel and Internals Project) Guidelines to which the station will eventually become committed and the recommendations of various SI L's. The specific components examined, the methods employed, the results of these examinations and the impact of identified flaws to plant safety are discussed in the following.

Jet Pump Beam Ultrasonic Examinations

An ultrasonic examination of all twenty jet pump hold down beams was performed by ComEd SMAD personnel in accordance with SPPM Procedure NDT-C-29 utilizing the new Siemens inspection fixture which now examines the engagement ears as well as the bolt area. All twenty beams were determined to be free of defects. These items were examined under work request number D960032097-01 and are examined every refueling outage as recommended in General Electric Services Information Letter (GENE-SIL) number 330.

Shroud Head Bolt Ultrasonic Examinations

An ultrasonic examination of all forty-eight shroud head bolts was performed by qomEd SMAD personnel in accordance with SPPM Procedure NDT-C-49. Bolts at locations 9, 14,19,24,28,32,37,41,43,45 and 48 for a total of thirteen were reported to contain flaws. Previously, after D2R14, bolts 9,15,18,28,33,37,41and45 were identified to contain flaws for a total of eight at that time. Two bolts, numbers 15 and 18 previously declared flawed, were not reconfirmed this outage and have been declared acceptable. Bolt number 8 was determined to be damaged by galling and not functional during installation after D2R14.

Prior to replacing the moisture separator in the reactor, bolt numbers 8, 32 and 34 were replaced with new bolts and the remaining eleven flawed bolts were shuffled to achieve a configuration that optimizes tolerance for additional non-functional bolts. Bolt 37 (flawed) was to be shuffled to position 34 but would not fit in that location, so it was replaced with a new bolt.

During reassembly of the reactor, keepers on these bolts will on occasion not rise (engage) and as a result, those bolts must be considered "non-functional". A General Electric analysis (D.Drendel to G.Whitman dated February 5, 1996) was used fo provide guidance for an acceptable configuration of the bolting.

During the assembly of the Shroud head, all forty-eight keepers were verified to have risen to engage their respective bolt heads with an underwater camera and so no additional bolts are considered to be "non-functional".

Core Spray Ultrasonic and Visual Inspections

The internal Core Spray piping inspections were performed in_ accordance with the recommendations of BWRVIP-18, "BWR Core Spray Internals and Inspection Guidelines". The inspection scope consisted of an automated inspection of the welds from and including the two RPV Core Spray nozzle's thermal sleeve to junction box inlet pipe welds, through the junction boxes, the headers and downcomers, and to the four shroud penetration thermal sleeves to shroud welds. Where access was restricted to this equipment, the weld was visually examined (Enhanced Visual Inspection, EVT-1, which resolves a 0.0005" wire) to assure 100% coverage where possible. EVT-1 was performed at locations designated "P4d" and "P8a" where the ultrasonic inspection equipment is not fully qualified. Inspection equipment is "Qualified" per methods described in BWRVIP-03, "Reactor Pressure Vessel and Internals Inspection Guideline". Where flaws were identified by UT, the area was supplementary EVT-1 examined. Additionally, all wall brackets were visually examined on this piping using a "Modified VT-1 "(MVT-1) which resolves a 0.001" wire.

Internal to the shroud, "baseline" EVT-1 examinations were performed on the four Core Spray tee-box cover plate and sparger connection welds and the sparger end caps. Also,. MVT-1 examinations were performed on all sparger nozzle, piping, and sparger brackets and tee-box gusset welds .

General Electric issued two reports summarizing the results of (1) the visual inspections (IWI), Report DRD-98-1 HDM9 and (2) the ultrasonic examinations of the Core Spray piping in the reactor vessel, Report# 1 HL4C.

The results of the ultrasonic examination identified three previously not identified (new) cracks and reconfirmed three cracks identified during D2R14. Two of the new flaws could not be confirmed visually. One is internal to the 80° downcomer Slip Joint (1 PS) and the second is at the 110° downcomer shroud thermal sleeve (2P8a) where extensive weld undercut is present. The third new flaw is at the 260° downcomer elbow to shroud weld (3P4d) and was the only new flaw to be visually confirmed at about 1.5" in length.

Flaws that were identified during D2R14 were more accurately characterized with this (automated UT) examination. The flaw located on the 260° downcomer at the thermal sleeve (3P8a) was measured during D2R14 using a manual ultrasonic technique to be 8.5" long. The more refined technique employed during D2R15 determined the length of the flaw to be 4.60". The second and similar flaw on the 290° downcomer (4P8a) was previously determined to be 2.0" is now determined to be 1.70" in length. The third flaw, weld 3P4c on the 260° downcomer at the top side of the lower elbow, originally measured at 3.5" is now confirmed to be 2.98" in length.

An evaluation of the Core Spray flaws was conducted by Sargent & Lundy utilizing limit load analysis techniques (Calculation numbers DRE-98-0050, -0066 and -0067, completed 4/7/98 and Report number SL-5197, Dresden Unit 2 Core Spray Flaw Evaluation Report, dated 4/10/98).

Spring 1998 lnservice Inspection Unit 2; National Board No. N-137 Commercial Service Date: 6-9-72


The results of this a:n·alyses demonstrate that the Core Spray downcomer piping is capable of withstanding all normal operating, design basis and "beyond design basis" loadings in this current degraded condition for two cycles of operation. Consequently, no repairs of this piping were attempted this outage and Operability Evaluation 98-020 was closed "Operable with No Concerns".

The condition of the degraded Core Spray piping will continue to be monitored by following the recommendations of the BWRVIP-18, "BWR Core Spray Internals Inspection and Evaluation Guidelines" during subsequent outages.

Jet Pump Riser Piping Visual Examinations

Recommendations for the inspection of Jet Pump riser piping is addressed in General Electric Service Information Letter (SIL) number 605 and in BWRVIP-41, "BWR Jet Pump Assembly Inspection and Flaw Evaluation Guidelines". During D2R15, the three butt (BWRVIP-41 weld designations RS-1, 2, 3) and two fillet (RS-4 and 5) welds on each of the ten risers were selected to be visually examined using the EVT-1 method. The RS-1 weld has been found flawed at two other plants. BWRVIP-41 classifies these welds as "high priority" since their failure could result in the disassembly of jet pumps and render 2/3 core height unachievable in a LOCA.

The results of Jet Pump riser inspections are included in the GE IWI report. One riser located between Jet Pumps 15 and 16 was identified to contain a short (1.5" long) IGSCC flaw on the elbow side of it's RS-1 weld.

A General Electric "Handbook", report number GE-NE-523-813-0169-054 Revision 0, was issued in June of 1997 to address potential flaws on Dresden's Recirc riser piping. Flaw Evaluation Report SGRVP-98-0023, dated 4/10/98 was prepared by Com Ed using the information contained in the "Handbook" to demonstrate that the riser piping is capable of withstanding all normal operating, design basis and "beyond design basis" loading conditions with the flaw present for at least two operating cycles. The Flaw Evaluation also addresses LPCI leakage through the flaw which was determined to be within the Siemen's (fuel vendor's) LOCA analysis limits which was verified by NFS (reference NFS letter NFS-BSA:98-035, dated 4/7/98).

The Flaw Evaluation's conclusion will be that considering the presence of the flaw with anticipated growth, the Recirc system piping will remain operable, within Code allowable stresses and within the LOCA Analysis allowed leakage limits for two fuel cycles.

Core Shroud Repair Assembly Inspection

The four "tie-rod" assemblies installed to alleviate concerns over circumferential shroud cracking during D2R14 by General Electric were inspected as established in BWRVIP-07, "Guidelines for Reinspection of Core Shrouds". The designer of the shroud repair (GE) provided inspection . points and acceptance criteria. Contact points at the shroud and vessel wall, thread engagement and locking devices (keepers), and clearances at clevis pins were specifically examined as was the condition of the four core plate wedges.

No areas of concern were identified .
