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: Wed, 29-01-1997
ERF description: On August 5, 20 and 21, unusual high activity up to 2203 Bq/m3 was reported by the Health Physics surveyor in the I-131 plant room during routine air sampling. Investigations revealed that the ventilation of the building was shut down during off-working hours. Due to the closure of exhaust/ventilation system, the negative pressure in I-131 cell was lost and the pressure in the cell became in equilibrium with room pressure, thereby by un-utilized Iodine-131 vapors in the fume hoods diffused and escaped the cell causing spread of radioactivity in the plant room. The Iodine-131 released ws from the left-over of the process. Had it been the total amount of Iodine which is 10 Curies (designed capacity of the plant) the situation would have been more severe.
