Nuclear Power Plant MCQs : This section focuses on the "Nuclear Power Plant" in Electric power system. These Multiple Choice Questions (MCQs) should be practiced to improve the Electric power system skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
A _________ is a thermal power station in which the heat source is a nuclear reactor
A. steam power plants
B. nuclear power plant
C. gas turbine power plants
D. All of the above
Explanation: A nuclear power plant is a thermal power station in which the heat source is a nuclear reactor.
In thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity.
C. Can be true or false
D. Can not say
Explanation: True, thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity.
Electricity was generated by a nuclear reactor for the first time ever in?
Explanation: Electricity was generated by a nuclear reactor for the first time ever on September 3, 1948
Nuclear reactors usually rely on _________ to fuel the chain reaction
Explanation: Nuclear reactors usually rely on uranium to fuel the chain reaction. Uranium is a very heavy metal that is abundant on Earth and is found in sea water as well as most rocks
A _______ is the amount of time it takes for half of a sample of a radioactive element to decay.
Explanation: A half-life is the amount of time it takes for half of a sample of a radioactive element to decay.
How much coal is required to generate energy equivalent to the energy generated by 1 kg of uranium?
A. 30000 tonnes of high grade coal
B. 300 tonnes of high grade coal
C. 10000 tonnes of high grade coal
D. 3000 tonnes of high grade coal
Explanation: One of the main attention for nuclear fuel is the huge amount of energy that can be released from a small quantity of active nuclear fuel. The energy obtainable by completely using 1 kg of Uranium would give energy equivalent 3000 tons of high grade coal i.e. Uranium has three millions times the energy of coal.
Nuclear fuel in reactor lasts for ________________
A. more than 5 months
B. few weeks
C. more than 5 years
D. few days
Explanation: Very small amount of nuclear fuel can produce very high amount of energy. Nuclear fuel may remain in a reactor for more than 5 years
Which particle is bombarded on heavy nucleus of nuclear fuel?
Explanation: Nuclear fission involvs bombardment of certain particles on heavy nucleus causing it to split. All modern fission reactors uses neutron particles for this purpose because they are neutral in charge and so, they can make their way through the shells of electrons and then through the nucleus at low energy
The fuel mainly used in nuclear fission reactors are:
Explanation: The materials U235,U233 and Pu239 are called fissionable materials. From all the above mentioned fuels only U235 will fission in chain reaction.
The water level in the steam generator and the nuclear reactor is controlled using the feedwater system.
C. Can be yes or no
D. Can not say
Explanation: Yes, The water level in the steam generator and the nuclear reactor is controlled using the feedwater system.
