Attachment to CP&L Letter of Response to NRC Report RII: NM 50-400/82-38 Reported Violation:
10CFR 50, Appendix B, Criterion V, as implemented by the PSAR section 1.8.5.5 and CP&L Corporate QA Manual section 6, requires that activities affecting quality be performed in accordance with documented instructions and procedures of a type appropriate to the circumstances. Construction procedure number WP-203 is the work procedure used for the installation of seisnically supported electrical cable trays. This procedure gives the torquing requirements for cable tray holddown bolts and cable tray splice bolts.
Contray to the above, on cable tray section X1803SA, running from plan points 2982 through 2986, the following items were identified:
1.
Twelve (12) cable tray splice bolts did not have the specified torque of 25 15 ft/lbs applied. This installation had been inspected and accepted in accordance with the sampling program describe in QC procedure number TP-42.
2.
One cable tray holddown bolt was found not to have the specified torque of 55 15 ft/lbs applied. This was also QC inspected and accepted.
This is a Severity Level V Violation (Supplement II).
Denial or Admission and Reason for the Violation:
The violation is correct as stated. A sampling-type inspection was adopted to provide a level of confidence, versus 100 percent verification, of corpliance with the specified torque values.
Corrective Steps Taken and Result Achieved:
Field Change Request FCR-AS-2378 has been issued which now permits cable tray splice plate bolting to be installed snug-tight versus specified torque values.
Specified torque values for tray holddown bolts remain unchanged. The sampling-type inspection for cable tray bolting has been changed to a 100 percent inspection program. The bolting for cable trays installed under the sampling-type inspection will be 100% reinspected to the specified requirements.
Corrective Action Taken to Avoid Further Noncompliance:
Technical procedure TP-42, Inspection of Safety Related or Seismically Installed Raceways and Components, has been revised to require 100 percent inspection of torque values for cable tray holddown bolts and for 100 percent inspection of snug-tightness of cable tray splice plate bolts.
Date When Full Compliance Will Be Achieved:
Full compliance will be achieved by 4/1/83.
