Mr James G Keppler Office of Inspection and Enforcement Region III US Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, IL 60137 DOCKET 50-255, LICENSE DPR PALISADES PLANT - ER-77-02, ER-77-11, ER-77 TECHNICAL SPECIFICATIONS LIMITS -

SODIUM, pH, CONDUCTIVITY As a result of recent discussions with your staff and DOR staff, we have con-cluded that any chemistry excursion, as identified by Section 3.18 of the Palisades Plant Technical Specifications, that occurs during power operation shall be reported even if it does not exceed the allowable time limit.

The attached reportable occurrence (ER-77-11) was not reported previously because this item had not been resolved.

Corrected versions of ER-77-02 and ER-77-17 are being resubmitted at this time.
