It is proposed to use the nuclear fusion reaction
in a nuclear reactor of 200 MW rating. If the energy from the above reaction is used with a 25 per cent efficiency in the reactor, how many grams of deuterium fuel will be needed per day. (The masses of 
and 
are 2.0141 atomic mass units and 4.0026 atomic mass units respectively)
Text Solution
Verified by ExpertsCHECK THE SOLUTION.
Sol. Mass defect in the given nuclear reaction,
Therefore, energy released
Efficiency is only 
, therefore,
i.e. by the fusion of two deuterium nuclei, 
energy is available to the nuclear reactor.
Total energy required in one day to run the reactor with a given power of 200 MW ,
:. Total number of deuterium nuclei required for this purpose,
Mass of deuterium required 
Number of g - mo 
so f deuterium required
