SUMMARY
Reactor power was mairtained at approximately 100% full power for the majority of the month. On December 7,1997, at 0000 hcurs, reactor power was reduced to approximately 92% to perform monthly turbine valve testing. At the completion of testing at 0255 hours0.00295 days <br />0.0708 hours <br />4.21627e-4 weeks <br />9.70275e-5 months <br />, power was increased to 100%.
