Hd HTkfCH Separated from grid and manually scrammed the reactor because of high condensate conductivity. The high conductivity in the condensate system was caused by the following: approxi-mately nine extraction line expansion Joints inside the condenser failed.

h is failure caused the 1/4" steel penthouse around t,hese expansion joints to deform and break apart. We metal from the penthouse fell on top of the condenser tube and caused them to start leaking. Approximately 5-6 days- i

On September 6th, the unit was separated from the grid because of high condensate conductivity. The conductivity was caused by some failed expansion joints inside the condenser which caused some condenser tube leaks. The outage was extended approximately six days to inspect the reactor recirculation pump nozzles.-

Total outage time was 423 hours0.0049 days <br />0.118 hours <br />6.994048e-4 weeks <br />1.609515e-4 months <br />.
