SUMMARY

Per our conversation, CP&L requests a meeting as soon as possible with NRC management to discuss our need for early NRC approval of our exemption request (per Reference

1) which will allow removal of primary loop whip restraints.

BACKGROUND CP&L provided in References 1 and 2 substantiating documentation and requested an exemption to

10CFR50, Appendix A, criterion 4, with respect to asymmetric blowdown loads resulting from discrete breaks in the RCS primary loop.

This documentation was prepared using the guidance of Generic Letter 84-04 (Reference

3).

Based upon the technical confidence and industry justification for this exemption request and the long-term man-rem savings due to increased

access, CP&L is in the process of simplifying the inefficient design and cumbersome construction imposed by the loop whip restraints.

The simplified design concept starts with removal of the whip restraints located in the primary shield wall.

The Company's design/construction schedule requires that our exemption request be processed as quickly as possible.

To help in this regard, CPGL proposes a

CP&L/NRC management meeting as soon as possible.

Please contact me as soon as such a meeting can be scheduled.

Thank you for your cooperation.

Yours very truly, BZ S.
