A major scientific concern over nuclear energy is how to--
store the waste products safely
reduce the high levels of carbon dioxide emitted into the air
deal with the large amounts of fossil fuels required
prevent the depletion of the ozone layer
What physical process in nuclear reactors is used to produce heat?
Combustion
Fission
Fusion
Conduction
What does the heat produced in a nuclear reactor do?
It is used to cool down the reactor core.
It is used to make steam that spins a turbine to create electricity.
It is used to increase the temperature of the reactor for better efficiency.
It is used to generate light.
How is electricity generated in a nuclear reactor?
By burning fuel rods
By converting water into steam to spin a turbine
Through solar panels
By using batteries
What is the purpose of pumping water into the reactor core under high pressure in a PWR?
To generate electricity directly
To cool down the reactor core
To prevent the water from boiling
To create steam for the turbine
Where does the production of steam occur in a boiling water reactor (BWR)?
Outside the reactor vessel

What happens to the core water after it has been used in the heat exchanger in a PWR?
It is discarded as waste
It is cooled in the cooling tower
It cycles back to the reactor to be reheated
It is converted into steam for the turbine
Enriched uranium is required as a fuel in a nuclear reactor, if light water is used as moderator and coolant, because light water has
High neutron absorption cross-section
Low moderating efficiency
High neutron scatter cross-section
Low neutron absorption cross-section
The control rods in the control system of nuclear reactors are used to
Absorb excess neutrons
Control fuel consumption
Control temperature
All of these
What is the primary function of control rods in a nuclear reactor?
To absorb excess neutrons and regulate the fission process
To generate heat by undergoing fission
To cool down the reactor core
To convert water into steam
Which of the following is a major advantage of using nuclear power plants for electricity generation?
They produce no greenhouse gas emissions during operation
They have unlimited fuel resources
They are the cheapest form of energy
They can be built quickly and easily
In a Pressurized Water Reactor (PWR), what is the role of the pressurizer?
To maintain the water in a liquid state at high temperatures
To convert water into steam
To cool down the reactor core
To absorb excess neutrons
