EVALUATION OF ENCLOSED MATERIAL Issues now before the Rancho Seco Licensing Board encompass control of auxiliary feedwater system flow rates. The enclosed material appears to be relevant to these issues. The enclosure is a letter from Babcock

& Wilcox to the Sacramento Municipal Utility District pointing out the potential concerns associated with the overfilling of steam generators.

The letter requests that the utility undertake a review of the effect of overfill on the main steam line pipes.
