1976 RAPS-2
Reactors were flooded due to construction errors. Emergency Core Cooling System got obstructed and this could have led to a meltdown.
1980 MAPS
Zircalloy pieces found in the moderator pump following cracking of the reactor inlet. This led to de-rating of the reactor from 235MWe to 175MWe, resulting in colossal economic loss.
1988 MAPS
Heavy water leak exposed workers to high radioactivity and forced the plant to shut down.
1992 RAPS-2
Fire spread through 4 out of 8 pumps. Had the potential to affect the cooling system leading to a meltdown - a serious nuclear accident.
1993 NAPS-1
Fire triggered by broken turbine blades led to near-meltdown. This could have led to a partial explosion.
1994 Kaiga-1
The pre-stressed concrete dome collapsed resulting in dispersal of radioactivity.
KAPS-1 & 2
Flood water entered condenser pit and turbine building basement. The soaked cable trenches threatened the secondary safety system endangering the entire safety back-up.
1999 MAPS
Four tonnes of heavy water leaked exposing workers to high radioactivity.
Recurring TAPS
Extensive tube failures have resulted in de-rating of the reactor and massive losses.
