With regard to the inspection above the inspector noted, on June 10 1982, that there was a gap between the bottom of a W14x167 column base plate and the pedestal capping grout except at the shims. This column is located at AZ 72 in the Unit 2 containment tunnel area. Subsequent licensee examina-tion indicated that a 1/16" to 1/64" gap existed all the way around the column base, except at the shims, extending two to seven inches under the f base plate. The inspector indicated that the lack of bearing appeared to be the result of poor grouting technique, rather than welding stresses, as evidenced by the seven inch depth. At the time of this inspection it could not be determined whether the reduced column base bearing area was consistent with the column design criteria. The licensae indicated that they would look further into the matter. The inspector stated that the above would be unresolved item 413/82-15-02 and 414/82-12-02: " Column Bearing."

Within the areas examined no violations or deviations were note . Safety-Related Piping (Unit 2)

The inspector observed non-welding work activities for safety-related piping as described below to determine whether applicable code and procedure requirements had been met. The applicable code for safety-related piping is the ASME B and PV Code,Section III, Subsection NC and ND 1974 edition with addenda through Summer 197 Observation of Non-Welding Activities (1) Review of specific work activities records was conducted to determine conformance, where applicable, with the following inspection and/or work procedures, record keeping, installation specifications or plans, specified materials, specified NDE, calibration and use of proper test equipment, and qualified inspection and NDE personnel. (Actual obervation of work was not possible as the window of opportunity had passed.)

The records review included, where applicable, the following; material test reports /

certification records, vendor manufacturing certifications, NSSS manufactruers quality release forms. Receiving inspection reports (including records of disposition of nonconforming materials) installa-tion records (checklists, isometrics, NDE and inspection. hydrostatic testing, cleanliness, qualification of inspection personnel).

The inspector observed welding and non-welding activities associated with structures and supports during various stages of weld completion. Observa-tions were made in order to determine whether the requirements of applicable specifications, standards, work and/or inspection procedures had been met for the activities involved and in the following stages of weld completion: Non Welding Activities (1) Review of Quality Reccrds

(a). Structures and Supports Inside Containment The inspector reviewed quality records for the below listed completed and accepted structures and supports in the area of installation / erection and inspection (QC). The review was made to determine whether those records met established procedures and reflected work accomplished consistent with NRC requirements and SAR commitment Applicable Structure Unit Drawing Code Suplementary 1 CN-1684-NC-102-B AWS-DI.1-72 Steel Frame "B" Frame B 1 CN-1684-NC-017-B AWS-DI.1-72 W14x167 2 CN-1051-6S7 AWS-D1.1-72 Columns (Tunnel Area)

Applicable Support Unit Drawing Code Frame "F" 2 CN-1073-10511 AWS-DI.1-72 Pressurizer 1 CN-1070-14 AWS-D1.1-72 Lower Support With regard to the inspection above the inspector noted, on June 10,1982, a fillet weld on Frame F, required by the drawing to be 8" X 5/16" that was in fact 7 5/8" X 5/16". The licensee subsequently documented this cordition in NCI N . The above is part of unresolved item 413/82-15-01 and 414/82-12-01 discussed further in paragraph 7a (1)(b).

(b). Structures and Supports Outside Containment The inspector reviewed quality records for the below listed structures and supports in the area of material, installa-tion / erection and inspection (QC). The review was made to determine whether these records, met established precedures and reflected work accomplished consistent with NRC require-ments and SAR commitment Applicable Structure Unit Drawing Code Boron Recycle 1 CNM-1148.00-26 ASME III ND Holdup Tank "A" CNM-1148.00-27 74S75 CNM-1148.00-28

The vender welds attaching the anchor lugs to the boric acid tank were not as specified on the drawing. Reinforcing fillet welds in some cases were undersize or missing and the specified full penetration welds showed little or no evidence of full penetration. This condition was subsequently documented by the licensee on NCI-1497 The above combined with the example cited in paragraph 7a (1)(a) indicate that welding inspectors had accepted welds that did not comform to drawing requirements. - The licensee indicated that they would investigate the matter to determine the extent of the problem. The inspector stated that the above would be evaluated for significance upon the completion of the licensee's investigation. This matter will be identified as unresolved item 413/82-15-01 and 414/82-12-01: " Structural Weld Deficiencies".

(Actual observation of work was not possible as the window of opportunity had passed.)

(1) The inspector examined records of weld joint fitup, prior to welding, to determine whether weld identification / location, joint

preparation and alignment and QC verification were in conformance with existing requirement Several welds on each of the i structures and supports listed in paragraph 7a (1)(b) were so ex eni ned.

(2) The inspector examined records of weld joints, and weld joints

where welding was in progress to determine whether weld identi-fication, weld procedures, welder qualification, weld material, defect removal (if applicable), specified NOE and periodic checks of welding variables were in conformance with existing require-ments. Several welds on each of the structures and support listed in paragraph 7a (1)(b) were so examine Within the areas examined no violations or deviations were identifie . Licensee Identified Items (50.55(e))

(Closed) Item 414/CDR 81-032: " Inappropriate Welding Procedure Specified For Pressurizer Upper Lateral Supports" On December 21, 1981, the licensee notified IE:II of a 50.55(e) item concerning the inapppropriate specifica-tion of welding procedures. The final report was submitted on January 21, 1982. The report has been reviewed and determined to be acceptable by IE:I The inspector held discussions with responsible licensee and/or contractor representatives, reviewed supporting documentation, and observed representative samples of work to veri fy that the corrective actions identified in the report have been completed.
