SUMMARY

November, 1981

~

11/1/81 - 11/12/81 Reactor power was maintained at 95% (power was reduced to 95% due to a leaking extraction steam bellows expansion joint in No. 1 Low Pressure Turbine to No. 1 Deserator) until 0925 hours0.0107 days <br />0.257 hours <br />0.00153 weeks <br />3.519625e-4 months <br /> on November 5, 1981, when reactor power was reduced to approximately 83%. This power level was maintained until November 7, 1981, when it was further reduced to 66%. These reductions of power were necessary due to indications of further degradation of the expansion joint.

11/13/81 - 11/30/81 A manual reduction of reactor power was initiated at 1900 hours0.022 days <br />0.528 hours <br />0.00314 weeks <br />7.2295e-4 months <br /> on 11/13/81 for an expansion joint outage.
