Research currently underway to increase the burn-up (cumulative amount of energy extracted from a unit mass of fuel) of the oxide fuel that will be used in fast breeder reactors will help in reducing the cost of electricity generated. The oxide fuel to be used in the Prototype Fast Breeder Reactor (PFBR) coming up at Kalpakkam will have a burn-up of 1,00,000 MW days/tonne. Scientists at the Indira Gandhi Centre for Atomic Research (IGCAR) are working to increase the burn-up of the oxide fuel to 1,50,000 MW days/tonne by 2011 and ultimately to 2,00,000 MW days/tonne.
