    The operation of a nuclear reactor is said to be critical, if the multiplication factor \[(k)\] has a value                                

    A)  1               

    B)  1.5

    C)  2.1             

    D)  2.5

    Correct Answer: A

    Solution :

     The multiplication factor \[(k)\] is an important reactor parameter and is the ratio of number of neutrons present at the beginning of a particular generation to the number present at the beginning of the next generation. It is a measure of the growth rate of the neutrons in the reactor. For \[k=1,\]the operation of the reactor is said to be critical. Note: If\[k\]becomes greater than one, the reaction rate and the reactor power increase exponentially. Unless the factor k is brought down very close to unity, the reactor will become supercritical and can even explode.
