SUMMARY
OF OPERATING EXPERIENCE FOR AUGUST, 1989 Palisades began the month of August with power maintained at 80%.
On August 4 at 1949 hours0.0226 days <br />0.541 hours <br />0.00322 weeks <br />7.415945e-4 months <br />, the reactor underwent an automatic trip while DC ground trouble-shooting was being performed.
During transfer of preferred AC Bus Y20 to the Bypass Regulator, a fuse blew in the "B" Steam Generator level control circuit resulting in a loss of feed to the "B" Steam Generator.
Consequently, the reactor tripped 9n "B" Steam Generator low level.
The reactor was returned to critical at 10-4% power on August 7 at 0415 hours0.0048 days <br />0.115 hours <br />6.861772e-4 weeks <br />1.579075e-4 months <br /> with the main generator being synchronized to the grid at 1238 hours0.0143 days <br />0.344 hours <br />0.00205 weeks <br />4.71059e-4 months <br />.
Reactor power reached 80% on August 9 at approximately 0100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br />, and this level was maintained for the remainder of the month.
