Question
The CANDU design of these devices is partially named for its use of heavy water as a neutron moderator, as well as the country of Canada. For 10 points each:
[10m] Name these devices, which use control rods to limit the propagation of neutrons. The first one of these devices was known as Chicago Pile-1.
ANSWER: nuclear reactors [or fission reactors; prompt on reactor or CANDU reactor]
[10e] Control rods are often made with this allotrope of carbon, which is the so-called “lead” in pencils.
ANSWER: graphite
[10h] CANDU reactors can use thorium to generate uranium, which makes it one of these types of reactors that generates more fissile material than it uses.
ANSWER: breeder reactor
