The licensee, ,

will be refueling Unit 2 by early Jar.uary and will be prcviding us with their evaluations on the SOR switch experience, the long-term procram, and the justification for continued operation during implementation of the long-term program by December 22, 1986. Therefore, with the receipt of this information-and continued testing of the switches, short-term operation of La Salle Unit 1 is justified until we have completed our evaluation of the licensee's submittal.

We will keep you apprised of the resuitt of our evaluation.
