MANUAL REACTOR SHUTDOWN DUE TO LEAKAGE IN BLEED WATER RETURN PIPELINE

On January 7, 1996 Ignalina-2 was under normal operation at the thermal power of 3400 MW. Electrical power of Turbogenerators TG-3/4 was 700 MW/350 MW respectively. At 11:05 am during a routine room patrol leakage was found in a bleed water return pipeline. The leakage was located in a region of a 10 mm diameter pressure tap tube which cannot be cut off.
As required by the Technical Specifications Unit 2 was unloaded and shut down at 14:35. The deviation caused neither on-site nor off-site radiation impcat.
The reactor has been cooled down to enable repairs. It will take at least 5 days to remedy the defect.
