Verification of As-Builts Structures (37051)
The objectives of this inspection were to determine whether the as-built design and construction drawings and specifications correctly reflect the as-built structural condition of the plant; changes from the original design were properly reviewed and approved; and that plant seismic and other stress calculations were based on as-built conditions.
In this regard, the NRC inspectors reviewed the quality assurance program description, Revision 21, dated February 18, 1988, found in the Safety Analysis Report, and the following implementing procedures, specifications, and instructions:
Fabrication, Erecticn and Bolt-Up of Structural and Miscellaneous Steel, SSP-11, Revision 3, dated March 8, 1988, with Interim Change Notices (ICNs) through 13.
General Structural Welding Requirements, SSP-16, Revision 3, dated July 15, 1986, with ICNs through 2?..
Engineering Review Walkdowns, SSP-61, Revision 2, dated December 28,
1987.
Unit 2 Structural Steel Mapping Instructions, dated April 22, 1988.
Specification for Category I Structural Steel, 3A010SS0012,
Revision 5, dated August 22, 1986.
Specification for Erection of Stri ctural and Miscellaneous Steel, 3A010SS0026, Revision 8, dated June 15, 1987, with Field Change Notices (FCRs) BC 3741, BC 3848, and DC 2538.
The NRC inspectors performed a walkdown covering each elevation of all seismic Category I buildings, during which the structural steel connections were visually examined. During the walkdown, the NRC inspectors noted that a diagonal brace, which was shown on the design drawing, had been deleted from a platform at elevation -21 feet in the fuel handling building. The licensee did, however, provide a FCR No. EC-02216 which documented this change and the design review of the change.
In-the performance of the walkdown, a sample of 18 connections was established and each connection was inspected in detail.
The sample is described below:

The sample selected for inspection consisted of welded, bolted, and a combination of connections. The design drawings for each of the connections were reviewed in order.to establish beam and column size and configuration, weld size and location, bolt size and quantity.
The NRC inspectors-physically verified, by direct measurement, all of the accessible attributes.
The NRC inspectors reviewed the licensee's. inspection documentation, mapping drawings, report data sheets, vendor cut sheets, mark drawings, and inspection reports for torque testing for bolting and AWS D1.1
'
structural welding. All applicable deficiency. notices, nonconformance reports, requests for engineering assistance were also reviewed.
It was-also noted that four of the connections (those identified with a 1600 series drawing) had been part of a redesign effort associated with thermal expansion joints.
The redesign documentation and five additional FCRs were reviewed.
No violations or deviations were identified.

Exit Meeting
-
The NRC inspectors conducted an exit meeting on July 29, 1988, with the licensee personnel denoted.in paragraph 1.
The NRC resident inspector also attended. At this meeting, the scope and findings of.the inspection were summarized.
