The '93 Narora fire was investigated by an independent AERB committee. The fire resulted from the failure of two steam turbine blades. It could've caused a partial meltdown of the core. The blade failure was identical to several failures observed more than three years prior to the accident. GEC, which manufactured these turbines, had intimated these failures and sent corrected blade designs to bhel, who were their collaborators in manufacturing the turbines. bhel urgently conveyed to npc the need for blade replacement in the turbines at Narora, Kakrapar and Kaiga plants. Though this advice was given to the DAE/npc a couple of years prior to the Narora fire, no action was taken.
