ERF send date: Wed, 05-04-1995
ERF description: Dhruva reactor was in shutdown state since 24.8.94 for refuelling and other maintenance works. After removal of irradiated assembly, when a fresh fuel assembly was being lowered in pile position K-13, the assembly could not be lowered beyond the gauge ring region. Several attempts were made with wet storage block. The fresh fuel assembly which had seen the obstruction in the pile was inspected, and it was found that one of the 5 leaves of the bottom bulge had got bent. Subsequent investigations revealed the cause of the incident to be the use of improper gauge ring for the pile position K-13. The event is rated at level 0 of INES scale. The incident took place during reactor shutdown and involved fresh fuel. There was no significant implication for the safety of the plant as there was no
radioactive release nor was there any radiation exposure due to the incident.

Hence as per Section III-3.13 para. 2, the event is rated at level 0.
