• Area Code 517 788-0550 August 14, 1$)75 The Division of Reactor Licensing US Nuclear Regulatory Commission Washington, DC 20555 DOCKET 50-255, DPR-20, PALISADES PLANT -

CORRECTION TO AUGUST 5, 1975 LETTER REQUESTING STEAM GENERATOR INSPECTION INTERVAL EXTENSION By letter dated August 5, 1975, Consumers Power Company proposed a change to the Palisades Technical Specifications which would extend the steam generator inspection interval.

Graphs of a number of important chemistry values for the period of April 2, 1975 through July 31, 1975 and graphs of the observed primary to seconday leakage were attached to the letter as Figures A (1 through 8), B (1 through 8) and C (1 and 2).

A review of these figures has disclosed a number of minor errors as well as a need to improve the graphical presentation.

These corrections and improve-ments have been completed and these figures are enclosed.

Please destroy the previously submitted figures and attach the enclosed figures to the August 5, 1975 submittal.

The enclosed figures are all marked Revision 1.
