SUMMARY

- The plant operated at approximately 100% power for the entire month with the following exceptions.

On 12/06/91,. load was reduced to 50% due'to commencing a shutdown per Technical Specification 3.1.1.3.b for Moderator Temperature Coefficient

. concerns (i.e., MTC more negative than EOL limit). Discussions with the NRC and. Westinghouse resulted in a temporary waiver <f cocnliance for T.S.

's.l.1.3.b and full power operations resumed later that erf.

On 12/07/91, load was reduced to 96% to perform a Moderator Temperature Coefficient nearurement test on 12/09/91. Full power operation

. resumed on.12/09/91.

On 12/iS/91, load was reduced to 96% to perform a Moderator Temperature Coefficient measurement test on 12/17/91. Full power operations resumed on 12/17/91.
