Event Report Forms (ERFs) are filed to the IAEA. Sometimes there are multiple event reports, updating the rating, the event description. Here you only see the latest event report

ERF send date: Mon, 22-08-1994
ERF description: On August 21, 1994 Unit 1 was under normal operation conditions at a thermal power of 2340 MW with turbogenerator no. 2 at an electrical power of 750 MW. At 20:00 am routine surveillance detected the increased leakage in reactor building room 208/l where the ECCS pipe headers were located. The radiation monitoring system confirmed the presence of water leakage in the reinforced leaktight compartments encasing the left loop of the coolant recirculation circuit. At 21:32 the reactor was shut down in order to locate and eliminate the leak. The leaking joint weld is assumed to be located in the ECCS pipelines of 100 mm diameter.
