What is the purpose of a moderator in a nuclear reactor?
to absorb excess neutrons
to cool the reactor core
to slow down neutrons to the appropriate speed for fission
to shield the reactor from radiation
|
Which of the following materials are commonly used as moderators in nuclear reactors?
neither water nor graphite
water
graphite
both water and graphite
|
What is the term for the minimum amount of fissile material required to sustain a chain reaction?
reaction mass
chain limit
fission threshold
critical mass
|
What is the primary function of control rods in a nuclear reactor?
to generate electricity
to cool the reactor core
to initiate the fission reaction
to regulate the rate of fission
|
How do control rods affect the rate of fission in a nuclear reactor?
control rods are only used in emergency situations
control rods have no effect on the rate of fission
inserting control rods increases the rate of fission
retracting control rods increases the rate of fission
|
What is the purpose of the coolant fluid circulating within the reactor?
to absorb neutrons and slow down the fission reaction
to lubricate the moving parts of the reactor
to carry away heat generated by the fission process
to shield the reactor from radiation
|
How is the heat generated by the fission process used to produce electricity?
the heat is not used for electricity production
the heat is converted directly into electrical energy
the heat is used to create a temperature gradient for thermoelectric generation
the heat is used to boil water, creating steam that powers turbines
|
Which of the following is an advantage of nuclear power?
minimal radioactive waste
widespread public support for reactor sites
low carbon emissions during operation
low construction costs
|
What is a key challenge associated with nuclear power?
high operational costs
dependency on fossil fuels
fluctuating energy output
secure, long-term isolation of radioactive waste
|
Explain the process of nuclear fission and how it generates energy in a nuclear reactor.
|
What role do moderators and control rods play in managing fission reactions within a nuclear reactor?
