Nuclear Power Engineering MCQs
A nuclear reactor can’t be used for
the production of radioisotopes.
supplying intense fields or beams of neutron for scientific experiments.
marine ship propulsion.
none of these.
✅ The correct answer is option D.
H2 is a better coolant than CO2, due to its relatively
lower density.
higher specific heat.
non-reactivity to uranium.
lower neutron capture cross-section.
✅ The correct answer is option B.
Fuel for a nuclear reactor (thermal) is
uranium
plutonium
radium
none of these
✅ The correct answer is option A.
The electric power generation cost in nuclear power plant is less than that in a coal based thermal power plant, mainly because the
fuel cost per unit power generated is less.
thermal efficiency of the former is higher.
maintenance cost of the former is less.
none of these.
