OF OPERATING EXPERIENCE April 2005 The unit began the month at 100% reactor power.
On 04/20/2005 at 0200 reactor power was reduced to -97% for eddy current testing of 13B waterbox.
Power was further reduced to -95% due to a high condenser differential temperature on 13B waterbox.
The waterbox was cleaned and eddy current testing was performed and completed on 04/22/2005 at 1500.
Power was returned to 100% at 1715.
