FAST BREEDER REACTORS...."SUNSHINE" of Indian Nuclear Programme Over 55 years of Indian nuclear program, fast breeder reactors plays a key role. India's nuclear programme started with research reactors, grown up with thermal reactors and now rising high with FBRs. Owing to the scarcity of fissile fuel, FBRs become the backbone for the sustenance of nuclear power in India. Designing FBR is highly challenging in itself by reason of its exigent core design, safety issues, high fissile fuel inventory and economics. FBR core design is highly demanding because of large neutron flux of high energy...
