Thermal nuclear reactors using enriched uranium as fuel contains a maximum of __________ percent fissile material i.e. U-235.

Correct Answer: 3
Thermal nuclear reactors using enriched uranium as fuel contains a maximum of 6 percent fissile material i.e. U-235.

Consider the following statements.
1. The chain reaction process is used in nuclear bombs to release a vast amount of energy, but in nuclear reactors, there is no chain reaction.
2. In a nuclear reactor, the reaction is controlled, while in nuclear bombs, the reaction is uncontrolled.
3. In a nuclear reactor, all operating reactors are 'critical', while there is no question of 'critically' in case of a nuclear bomb.
4. Nuclear reactors do not use moderators, while nuclear bombs use them.
Which of the above statements about operational principles of a nuclear reactor and a nuclear bomb is/are correct?

Thermal nuclear reactors using 'enriched uranium' as fuel contain a maximum of . . . . . . . . percent fissile material i.e., U-235.

Fast breeder nuclear reactors using enriched uranium as fuel may contain upto a maximum of __________ percent of U-235 (i.e. fissile material).

Which of the following statement is true? I. In homogeneous reactors the nuclear fuel and the moderator represents a uniform mixture in the fluid form. II. In heterogeneous reactors separate fuel sludge or roads are inserted in the moderator III. Most of the nuclear reactors used these days are of homogeneous type

To meet its rapidly growing energy demand, some opinion that india should pursue research and development on thorium as the future fuel of nuclear energy. In this context, what advantage does thorium hold over uranium?
1. Thoriumis farmore abundant in nature than uranium.
2. On the basis of per unit mass of mined mineral, thorium can generate more energy compared to natural uranium.
3. Thorium produces less harmful waste compared to uranium.
Which of the statements given above is/are correct?

In which of the following reactors material converted into fissile materials is more than fissile material consumed?

Nuclear fuel generally used in reactors is uranium oxide instead of uranium, because the former has higher

U-235 content in enriched uranium, that is normally used in power reactors (e.g., at Tarapur atomic power plant), is about __________ percent.

Rearrange the parts of the sentence in correct order. Tarapur agreement guaranteed supplies of P : Tarapur reactors for entire life Q : enriched uranium fuel from R : the US for running the
