The function of control rods in nuclear plants is to
Reactors designed for propulsion applications uses
Solid fuel for nuclear reactions may be fabricated into various small shapes such as
Match List-I (Materials) with List-II (Application) the following:
1. Ferrite material
2. Control rods
4. Fissile material
A B C D
(a) 4 3 2 1
(b) 2 1 4 3
(c) 2 3 4 1
(d) 4 1 2 3
Which one of the following pairs is not correctly matched?
Identify the type of reactor which converts a ferrite material into fissile isotopes:
Natural uranium is made up of
There are many elements found in nature as mixture of isotopes of varying quantity such as naturally occurring Uranium called, natural Uranium
It is composed of
where the atomic number is 92 is all three cases.
The unit of radioactivity is
The process by which a heavy nucleus is splitted into two light nuclei is known as
The most commonly used moderator in nuclear power plant is
Moderator is used to slow down the neutrons as they come at very high velocity
Example of moderators
Energy released by the fission of one U-235 atom is nearly
Energy released by fission reaction depends upon the type of reaction.
The reaction given as
This reaction yields 196 MeV energy as fission of U-235 takes place.
A nuclear unit becoming critical means
The moment, nuclear power plant starts producing nuclear power, it is said that nuclear power plant goes critical.
Which one of the following types of nuclear reactor does not require a heat exchanger?
Boiling water reactor
In boiling water reactor no heat exchanger is required a mixture of water and steam comes out through the core and steam is separated and allowed to expand in the turbine.
In fast Breader Reactor
The risk of radioactive hazard is greatest in the turbine with the following reactor:
