Question

In a nuclear power plant, Choose one: A. control rods regulate the rate of the reaction by releasing excess neutrons. B. pitchblende (U238) is the most common fuel. C. there must be enough nuclear fuel to exceed a critical mass. D. fusion is happening.

Answer 1

Answer:

option A.

Explanation:

The correct answer is option A.

Nuclear power plant are used to generate electricity. In these power plant energy is produced by fission in the nuclear reactor.

The most common fuel used for the production of energy is U-235.

Control rods are inserted in the reactor if energy requirement is less and when energy requirement is large Control rods are remove. Hence, we can say that control rod can be used to regulate the reaction in the nuclear power plant.
