An flRC Construction Appraisal Team (CAT) inspection was performed in February and March 1984, for the Waterford Steam Electric Station (WSES) Unit 3 at As part of this inspection, records of the liRC Region IV Taf t, Louisiana.
inspection program were reviewed to identify those portions of the construction program that have been completed and those portions currently being performeo.
The results of this review indicatud that the construction inspection program was approximately 90 percent complete at the start of the inspection.
The total man-hours of direct inspection effort performed by Region IV in 1983 was
- 1239, A number of deficiencies identified during the CAT inspection had been pre-viously identified by the regional inspection program.
These included addf-tional loads on seismic supports, pipe to structure clearance problems and inconsistent insulation resistance testing of electric motors.
The CAT inspec-tion found that the applicant had not met his commitments for corrective action for these and other areas.
The Regional inspections had also identified several deficiencies regarding the a'pplicant's control of drawings and documents. While the CAT found design change control generally in conformance with requirements, examples were found of affected drawings and specifications not identified by the design change documents and approval of design changes without an approved design change ducument.
Two significant problems were identified by the tiRC CAT in the electrical and Instrumentation construction areat numerous raceway separation violations, j
and undocumented loads on raceway seismic supports. The separation violations had not been previously identified by the regional inspections.
It is noted, however, that the electrical inspections had not been completed. The undocu-mented loads on seismic supports was criginally identified by a Region lY inspe: tion; however, the applicant failed to implement their stated corrective action.
tio significant problems were identified by the CAT in the civil and structural area, and material traceability.
In the mechanical area, the CAT inspection found a continuing problem with an issue originally identified by a Region IV inspection; the clearance criteria between pipes, supports, structures, tubing, and raceway. The applicant had not met his comitment to assure that interferences were identified and evalu-ated. Additionally, pipe supports and restraints deficiencies being found af ter repeated inspections reflect an ineffective inspection program.
When problems with a contractor's (American Bridge) welded and bolted connee-tions were identified, the applicant committed to Region IV to evaluate all aspects of the American Bridge structures. While the CAT findings in welding and fide support the adequacy of corrective action for American Bridge welding, deficiencies were found in shop welds made by an American Bridge vendor. Only one unacceptable radiograph was found by the llRC CAT inspection.
s I
L The Regional construction inspection progree has resulted in the identification of a number of significant findings. Two areas were identified by the CAT Inspection where more regional efforts could have been effective, inspection of electrical raceway separation and followup on the applicant's corrective actions.
The Region's concern for the effectiveness of the inspection program in general and the CAT inspection in particular was evident in their support of the CA:
