    Consider the following statements
    1. The Fast Breeder Test Reactor (FBTR) is at Kalpakkam, and it is a fore runner to the second stage of the country's nuclear power programme.
    2. Past reactors use 'Fast' (high energy) neutrons to sustain the fission process, in contrast to water cooled reactors that use thermal (low energy) neutrons. Which of the above statements is fare correct?

    A)  Only 1 

    B)  Only 2

    C)  Both 1 and 2    

    D)  neither 1 nor 2

    Correct Answer: C

    Solution :

    [c] Fast breeder reactors constitute the second stage of India's three stage nuclear energy programme. The Fast Breeder Test Reactor built at Indira Gandhi Centre for Atomic Research, Kalpakkam, is for runner to the second stage of Indian nuclear power programme. The reactor design is based on the French reactor Rapsodie, with several modifications, which were made to suit India's requirement. Major modifications include the provision of a steam water circuit and indigenously developed turbine- generator in place of sodium air heat exchanger in Rapsodie. The reactor uses Pu-U mono-carbide developed indigenously as the driver fuel, and went critical on 18th October, 1985. Being a unique fuel of its kind without any irradiation data, it was decided to use the reactor itself as the test bed for this driver fuel.
