Exit Interview The inspection scope and findings were summarized on March 29, 1979 with those persons indicated in Paragraph 1 above.
The inspector identified the areas inspected which included safety-related piping record and radiograph review; reactor building refueling canal liner welding activities; steel liner (containment)
weld repairs; open storage and housekeeping; cable tray restraint installation.
No dissenting comments were received from the licensees 3.
Licensee Action on Previous Ins ection Findin s
Actions on previous findings were not reviewed during this inspectio.
Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve noncompliances or deviations.
New unresolved items identified during this inspection are discussed in Paragraph 6.
5.
Inde endent Ins ection Effort a.
Stora e and Housekee in Work areas inside the reactor and auxiliary buildings were inspected in order to observe work progress housekeeping conditions and control of unconsumed weld ei.ectrodes.
In the lay-down storage areas used to store safety-related components (piping), the inspector observed storage conditions including component identification, protection and segregation of noncon-forming items.
Within these areas the inspector noted that weld reinforcement geometry on certain B. F.
Shaw fabricated safety injection spools would preclude UT examination of the weld during preservice exami-nation. This matter was discussed with the licensee who agreed to review this area.
The inspector stated that RII would be looking again into this matter as pipe installation gets underway.
b.
Cable Tra Restraint Installation Cable tray restraint installation (welding) was in progress in the auxiliary building. Melding is being performed in accordance with the AWS Structural Welding Code D1.1-74.
The controlling docum'ent is Ebasco's engineering specification 2998-761 which references the aforementioned code, quality control inspection requirements, type and control of weld material. Instructions to the field are delineated under general notes on Ebasco's engineering drawing No.
2998-G-824, sheet 1, 8/1/77.
Inspection of welds is performed by QC personnel qualified under requirements of procedure CPL:QI5.1.
The inspector reviewed the aforementioned drawings, specifications, procedures and inspection personnel qualification records.
C.
Steel Liner (Containment)
Meld Re airs The inspector reviewed CBSI's Repair Check List (RCL) and Nonconformance Control List (NCL) to ascertain whether con-struction deficiencies relative to the containment liner have been
properly documented and whether appropriate and timely corrective action had been or would be taken.
In order to perform this task the inspector selected the following items for review:
NCL(s)876-98, "Miscellaneous Surface Cracks on Column Stub Areas
//1-/24" NCL//64 Laminar Indications on bottom edge of Ring E to F Girth Seam in Roof, Plate ll-l S/N 46" NCL//71, Gouge in Shell Plate 12-1-3 Cut Torch Generated NCL//73, "Slag Type Defect in First Shell Ring, 192 degree Azimuth.
Corrective action for the above items was discussed in depth with the CBRI site representative.
In reference to NCLj/64, CBGI stated that laminar type indications were discovered while arc gouging (preping) the weld seam.
Subsequent UT examination disclosed the presence of extensive (continuous)
indications with amplitudes ranging from 15 to 60 percent of CRT screen height.
CBSI's decision to replace the plate in question was documented in CBI's letter BBC-179, BBC-180 to the licensee.
Within the areas inspected, no items of noncompliance or deviations were identified.
6.
Safet -Related Pi in (Weldin -Review of ualit Records Unit 2 The inspector reviewed the quality records described below relative to safety related pipe welding to determine -whether these records reflected work accomplishment consistent with NRC requirements and SAR commitments.
The applicable code for this welding is the ASME Boiler'nd Pressure Vessel Code,Section III, 1971 Edition with Addenda through the Summer of 1973.
This is implemented by Ebasco's piping specification 62-72 to B. F. Shaw-the piping fabricator/vendor.
The following completed weld records were reviewed in the areas of.:
visual and dimensional inspections, weld history, vendor gA releases, code data reports, PT reports and radiographs, weld repair, welder
-4-identifications, and receiving inspection reports, as applicable to each weld:
Weld Number S ool Number
~Sstem I-6-SI-464-2 Safety Injection I-6-SI-111-6
,
Safety Injection I-6-SI-144-1A Safety Injection I-6-SI-181-6 Safety Injection While reviewing radiographs the inspector noted that on several instances welds near spool ends were radiographed, using the film side penetrameter technique.
The inspector stated that while this technique was permissible by code where inaccessibility precludes placing the penetrameter on the source side, this did not appear to be t'e case in the afore-mentioned spools.
The licensee agreed to review this matter.with B. F.
Shaw and report back on a subsequent RII inspection.
This matter was identified as unresolved item 79-06-01.
Within the areas inspected, no items of noncompliance or deviations were identified.
7.
Steel Containment Structures (Weldin )-Observation of Work and Work Activities The inspector observed field welding activities associated with the reactor building refueling canal liner (liner).
The applicable Code for erection/fabrication of the liner isSection III of the ASME Code 1974 Edition with addenda through the Winter of 1976 as implemented by Ebasco specification F1,0-2998-745 and drawing
/l2, R/4.
This drawing provides general and specific erection/fabrication information to the field.
The inspector observed welding activities where joint fitup and align-ment were complete and in progress to determine conformance with appli-cable specifications and procedures in the areas of: weld identification, specified weld procedures, qualified welders, specified weld material,
-5-specified NDE being performed and periodic checks of welding variables.
Welds selected for this activity were as follows:
Liner Weld Plate Numbers B"1 B-2 B-26 41-8-1 to 41-2"3 41-2-2 to 41-2-3 Knuckle 41-2-7 to 41-2-4 Assembliers B and J were being tacked to the knuckle plate.
equality
" records and receiving reports were reviewed for plates 41-2-7 and 41-2-4.
Observation of weld material control included: identification, segregation, oven temperatures, weld rod issue slips and control of unused material at issue stations and work areas.
equality records, receiving reports and control of stored material were reviewed for the following weld electrodes:
~Te Heat j/

sufficient number of qualified inspection personnel at the work area.
Within the areas examined, there were no items of noncompliance or deviations identifie '1
