The installation was found to be complete and accept-able.
On April 27, 1983, the Pre 79-14 Walkdown identified a sway strut out cf alignment.

On March 25, 1983, during the Pre 79-14 Walkdown, Hanger Engineer-ing examined this support and as documented on the Pre 79-14 checklist, the cotter pins were found to be in place.
Subsequent to the Quality Inspection and Pre 79-14 Walkdown, the NRC Inspector discovered the cotter pins to be missing.

Though the actual cause of the deficiencies is indeterminate, the investigation confirms that the inspection procedure is adequate.
Verification of correct cotter pin and retaining ring installation is a requirement of Daniel Quality Control Procedure QCP-200 (Inspec-tion of Fabrication and Installation of Safety-Related Pipe Supports),
Exhibit BI.
The subject cotter pins and retaining rings were inspected by Quality Inspection as evidenced by the Inspectors' initials on the specific items on the checklists.
Corrective Action To Be Taken To Avoid Further Noncompliance:
The Deficiency Reports written to document the identified deficiencies state the cause to be indeterminate because inspection records indicated correct installation.
As corrective action to discourage the possibility of tampering with hardware following inspection, Project Management has advised craft and supervision of the severe disciplinary action that they will take against individuals who engage
a
=
Mr.
R. C. Knop July 18, 1983 in such activities.
In addition they were also notified such acts are a violation of federal law.
The Constructor Pre 79-14 Walkdown, followed by the actual 79-14 Walkdown performed by the Architect Engineer provides a means to identify deficiencies such as the inspector reported.
Additionally, though not intended to be a detailed inspection, the final walkdown prior to Release for Test provides another opportunity for identifi-cation of deficiencies.
The Date When Full Compliance Will Be Achieved:
Full compliance will be achieved upon conpletion of the rework required for EF15-R003/314Q, scheduled to be complete by July 25, 1983.
If yoa have any questions regarding this responsc or if additional information is required, please let ma know.
