SUMMARY

OF OPERATING EXPERIENCE FOR SEPTEMBER 1994 The unit ran at full power until September 29.

Due to the need to saturate a new demineralizer with boron, there was a potential for an inadvertent dilution of the PCS.

As a precautionary measure, reactor power was lowered to 99% on September 29th and 30th for this process.
