==Dear Mr. Stello:==

Re:   St. Lucie Unit   1 Docket No. 50-335 Potential CEA-to-Guide Tube  Interaction Combustion Engineering     (C-E)  recently informed Florida Power 6 Light Company (FPL) of a potential CEA-to-guide-tube interaction that may lead to deterioration of the guide tube at a position corresponding to the long term resident position of the CEA's.
C-E has prepared a generic report to describe the phenomenon and 'has recommended repositioning CEA's about three inches different from their present position to minimize potential guide tube wear at a single location. This will,involve a Technical Specification amendment to support a withdrawal position less than that presently required by certain specifi-cations. The appropriate amendment is being prepared and will be reviewed by our on-site and off-site review groups.                We plan to forward the proposed     amendment   to  your office    no  later     than January 4, 1977.
In the interim,    we have  implemented weekly cycling of CEA's as requested by your    staff during   a telephone conversation on December 23, 1977. This additional surveillance will remain in effect until we    have implemented an approved Technical Specification amendment.
We  will keep   your staff  informed of our progress in        this matter.
Very  truly yours, obert E. Uhrig Vice President REU:MAS:sl cc:   Mr. James P. O'Reilly,   Region   II Robert Lowenstein, Esquire                                     780040i27 PEOPLE... SERVING PEOPLE
