1.
The role of a moderator in a fission reactor is to
slow down neutrons
absorb neutrons
cool the core
shield the workers from gamma-rays
2.
Why must fusion occur at very high temperature?
To produce neutrons
To overcome the strong nuclear force
To overcome the electrostatic repulsion between nuclei
To increase the mass of the nuclei
3.
A fission reaction releases about 200 MeV. In joules this is
3.2 × 10−17 J
3.2 × 10−11 J
1.25 × 1021 J
200 J
4.
A fission fragment has a higher binding energy per nucleon than the parent because
it is further from iron
it is lighter
it has more neutrons
it is closer to the peak of the curve
5.
In a controlled chain reaction, the average number of neutrons from each fission that go on to cause another fission is
0
2 or 3
exactly 1
as large as possible
6.
Which statement about fusion is correct?
It releases energy because products have lower binding energy per nucleon
It releases energy because products have higher binding energy per nucleon
It needs control rods
It uses uranium-235
