1. control temperature
2. control radioactive pollution
3. control absorption of neutron
4. control fuel consumption
control absorption of neutron
1. acts as good moderator
2. produces maximum steam
3. transfers heat from core at a fast rate
4. breeds neutrons
transfers heat from core at a fast rate
1. fast
2. slow
3. in bulk
4. static
slow
1. used fuel should be reprocessed
2. moderator should be used
3. coolant should be employed
4. control rods should be used
used fuel should be reprocessed
1. chain reaction can be initiated
2. it becomes uncontrollable
3. it explodes
4. it produces no power
chain reaction can be initiated
1. infinite
2. zero
3. exactly balanced by the loss of neutrons through leakage
4. initiated
exactly balanced by the loss of neutrons through leakage
1. at the lower rate than the consumption
2. at a higher rate than the consumption
3. at an equal rate of the consumption
4. depends on other considerations
at a higher rate than the consumption
1. almost same
2. slightly more
3. slightly less
4. much less
much less
