Question

control rods in a nuclear reactor.
select one:
a. remove heat from the reactor core.
b. provide fuel for the reaction
c. control a chain reaction by absorbing neutrons.
d. prevent the leakage of radiation into the environment.
the function of the heat exchanger in a nuclear reactor is to...
select one:
a. prevent the leakage of radiation into the environment.
b. convert water into steam, which turns a turbine
c. cool the reactor water.
d. absorb neutrons to slow down the chain reaction.

Explanation:

For the first question:

• Option a is incorrect; coolants remove reactor core heat.
• Option b is incorrect; fuel rods provide reaction fuel.
• Option c is correct; control rods absorb neutrons to regulate the nuclear chain reaction, speeding or slowing it as needed.
• Option d is incorrect; containment structures prevent radiation leakage.

For the second question:

• Option a is incorrect; containment structures block radiation leakage.
• Option b is correct; the heat exchanger transfers heat from reactor coolant to another water supply, turning it to steam that spins a turbine for electricity.
• Option c is incorrect; the reactor's cooling system handles cooling reactor water.
• Option d is incorrect; control rods absorb neutrons to manage chain reactions.

Answer:

1. c. control a chain reaction by absorbing neutrons.
2. b. convert water into steam, which turns a turbine
