An identical component on the same unit failed a year ago, causing an explosion and fire. The reactor was shut down at 1 p.m. Thursday after an online monitoring system identified a possible problem with the bushing, said Emily Christensen, PG&E spokeswoman. The shutdown will enable workers to conduct an in-depth inspection and make repairs if needed. Each of Diablo Canyon's two reactors has three transformer banks, which feed electricity generated by the plant into the electrical grid. The bushing connects the transformer to the high-voltage transmission line. A bushing on a different transformer bank of the same unit exploded in the middle of the night in August 2008 with enough force to break nearby windows. Insulating oil caught fire. No one was injured in that accident, but it caused the unit to be shut down for 20 days while repairs were made. Operators do not know how long this shutdown will last because they do not yet know whether repairs will be needed, Christensen said. The other unit continues to operate at full power.
