Reactor Concepts
SCRAM stands for this
What is Safety Control Rod Axe Man?
SFR is short for this
Steam spins this to generate power in a reactor
What is a turbine?
There are this many main Gen IV designs
What is 6?
The number of this neutral particle in atoms is the difference between isotopes.
What is a neutron?
This slows neutrons down enough to cause fission in a reactor
What is a moderator?
The most common coolant and moderator for nuclear reactors in use today.
What is water?
A PWR has one more of these than a BWR
What is a coolant loop?
The most commonly used generation today
What is Gen II?
This quantity represents how likely a given neutron interaction is to occur for a nucleus
What is a cross section?
Along with significant managerial oversight and SOMETHING-tipped control rods, this property was responsible for the Chernobyl accident.
What is graphite?
These reactors take up the most space compared with the other most commonly used reactor designs today.
What is AGR?
The name of the first reactor ever built
What is Chicago Pile-1?
The first-operated Gen-III reactor operated here
Where is Russia?
This type of material will not fission on its own, but will when hit by a neutron.
What is fertile material?
Reactor controls use these neutrons
What are delayed neutrons?
The first PWRs were designed for use on these
What are submarines?
The most common PHWR subtype; commonly used in Canada
What is CANDU?
The name of the first operational gen III reactor
What is VVER-200?
This gamma interaction dominates at high energies
What is pair production?
This property relates reactivity with gas bubbles in coolant/
What is the void coefficient?
HTGRs are at least this much more efficient than other conventional designs
What is 4%?
The Magnox reactor was used to breed this element
What is plutonium?
This percentage of Generation-II reactors have been given a license extension
What is 75%?
This type of nuclear fuel is used in HTGRs
What is TRISO?
