Attachment I Response to Appendix A Item of Noncompliance Infraction 10CFR 50, Appendix B, Criteria V, statei, in part, that:
" Activities affecting quality shall be prescribed by documented instructions, procedures or drawings... and shall be accomplished in accordance with these instructions, procedures or drawings.
The Limerick PSAR, Appendix D, Quality Assurars_e Program, Paragraph D.4.10 states in part, that the subcontractor "...shall have written procedtres governing the identification, sontrol, and disposition of materials, parts, or equipment that co not meet specification require-ments.
Repairs snall be in accordance with documented instruc+. ions."
The Supplier Deviation Disposition Request for Reactor Building #1 longitudinal tendon slippages, SDDR number L-12 Revision 3, January
- 29. 1979, states in part in Procedure (Item 3) for Rework of Slipped Strand, " Stress the strand to the required dead-end anchor force. A higher gage reading may be necessary to unseat and replace wedges.
Record elongation and force...".
Contrary to the above, as of May 9,1979, the elongation and force used to rework each of the slipped strands for stage 1 longitudinal tendons of the north and south fuel pool girders were not documented.
Response to Infraction A review of the existing documentation determined that documenting the elongation and force of the reworked strandt is not essential to the stressing operation and adequate documentation does exist to verify that the strands were satisfactorily reworked.
Therefore, the proced-ure has been revised to no longer require the documentation of the elongation and force.
To preclude recurrence of similar type problems, we have reviewed the subcontractor's procedures and have determined that the forms currently provide adequate space for reporting information cequired by the procedures.
In addition, the subcontractor's personnel have been re-minded to pay close attention to the documentation recording require-ments of their procedures.
