Chapter 30, Problem 84A

To determine

To Explain:

The need for two loops in the nuclear reactor.

Answer to Problem 84A

Two loops are required as the first loop will carry the water that passes through the core at high pressure will not boil and second loop will help to carry water at low pressure producing steam.

Explanation of Solution

Introduction:

Boiling water nuclear reactor is the reactor whose core heats water, turning directly into steam in the reactor vessel.

The pressurized water reactor is a type of nuclear reactor that is used to generate electricity.

Use of light water is made in this type of reactor as the medium of coolant and neutron moderator.

The water that will pass through the core will tend to have high pressure and hence will not boil.

Thus, there is need for the second loop to carry water which will be at low pressure that will produce steam.

Conclusion:

Hence two loops are required as the first loop will carry the water that passes through the core at high pressure won't boil and second loop will help to carry water at low pressure producing steam.
