SUMMARY
OFOPERATING EXPERIENCE November 1994
(
The unit began the month shutdown in mode 3 due to a reactor trip which occurred 10/2794 for a loss of electricalload. De cause of the trip was due to a failure of the A phase transition links to the Isophase Bus Duct. The links were replaced and the unit was again paral eled to the grid at 0051 on 11/6/94. Power was slowly escalated at the request of the dispatcher due to low demand on the grid.
Power was returned to 10C% at 0200 on 11/7N4.
l.
1 On 11/1894 at 2315 power was reduced for Temperature Coefficient testing. Reactor power was reduced to %.6% for the testing. De power was again returned to 100% at 2140 on 11/20N4 and l
remained there through the end of the month.
