Eummary A number of deficiencies were identified in the inspection documentation of structural steel installation. The deficiencies resulted from failure to follow inspection procedures and inadequate / confusing procedural requirements. The appropriate procedures have been clarified and the need for strict adherence to the approved procedures has been reemphasized to the QC personnel.

Evaluation of the procedural deficiencies has indicated that the structural integrity of the structural steel installation is not c ompromised. Had this ites gone uncorrected it would not have adversely affected safe operation of the plant. Therefore, this item is not reportable pursuant to 10CFR50.55(e)

II.

Damerintf an of Defie f mary Based upon a Quality Assurance surveillance and an audit, a number of deficiencies pertaining to the inspection documentation of structural steel installation were identified. The deficiencies can be categorized as follows:

A.

Some inspection reports were not properly filled out/ processed.

B.

Mapping of inspections on structural steel drawings, in many cases, was either inadequate or incomplete.

C.

Some inspection reports documenting the acceptance of structural steel connections / members could not be located / retrieved.

As the extent of inspection documentation deficiencies was unknown and the safety impact could not be defined, the item was identified as potentially reportable.

The documentation deficiencies were caused by:

1) Noncompliance to inspection procedures in the areas of

- proper filling out and completely annotating all the " blocks" of inspection reports.

- issuance, logging, and tracking of inspection reports to ensure that the Record Management System (RMS) receives them.

2)

Inadequate procedural requirements pertaining to mapping of connections / members.

>^ * ,

Filo No.: 012.286 Pag 3 2 of 2 III. Carrectiva Action The appropriate procedures were immediately revised esplicitly defining mapping requirements for both bolted and welded connec tions. These changes required espping of connections within l 30 days of quality Control (QC) acceptance, prior to embedding in concrete / grout. or prior to area turnover, whichever occurs first.

In addition, the procedure was clarified requiring the QC personnel to ensure that complete inspection reports exist documenting the final acceptance of all structural steel connections prior to their incorporation into concrete /groot placements. The QC personnel were trained to the revised procedural requirements and the need for strict compliance to the established requirements.

In order to determine the estent of documentation deficiencies associated with previous structural steel installations, the "eapping" process (annotating the corresponding inspection report number on drawings adjacent to the members or the joints) was initiated imunediately. The results of the espping completed to date and follow-up QA Surveillance performed has provided sufficient information to evaluate the safety impact described below.

IV.

Emeurranca Cantral The inspection procedures have been revised and the appropriate QC personnel have been retrained to prevent recurrence of the documentation deficiencies. A quality Assurance audit and surveillances have been performed to assess the effective loplementation of the revised inspection precedural rsquirements, and the results indicate proper adherence to the procedures.

V.

Safety Analvala As a result of " mapping" completed to date and the follow-up QA surveillances conducted, some additional deficiencies reisting to incomplete inspection reports and alssing or lost inspection reports have been discovered; however, these deficiencies are not wide spread and no hardware deficiencies have been identified.

We have concluded that the type of deficiencies found are insig-nificant to the safety of the structural steel installation.
