Reactor Components PWR, BWR, and
Valves
In a PWR what powers the reactor coolant pump? - correct answer-Electric Motor
In a PWR, the pressure of the RCS is maintained by saturated steam located in what
component? - correct answer-Pressurizer
There are two functions of the emergency core cooling systems (ECCS) in a PWR. One is to
provide core cooling to minimize fuel damage following a loss of coolant accident. The other
is to: - correct answer-To provide neutron poisons to ensure the reactor remains shutdown
following the cooldown associated with a main steam line rupture.
When taking a quiz, test, or exam, which Fundamental Human Performance Tool should you
use to ensure you have answered all questions? - correct answer-Self-Checking
What component associated the pressurizer of a PWR is used to increase pressure? -
correct answer-Electrical heaters
Which Conditional Human Performance Tool is performed when following a procedure to
perform a task in the nuclear industry? - correct answer-Placekeeping
Why is Boron used in the reactor coolant system (RCS) of PWRs? - correct answer-To
absorb neutrons
Which of the following is a correct definition of "decay heat" associated with a nuclear power
plant? - correct answer-Heat produced by the decay of fission products in the reactor core.
What is the function of control rods or control blades in a nuclear reactor? - correct
answer-Absorb neutrons
In what region of the world are the highest deposits of uranium found? - correct
answer-Australia
What is the function of a moderator in a nuclear reactor? - correct answer-Slows down
neutrons
In the secondary system of a PWR, steam entering the turbine comes from: - correct
answer-Steam generators
The secondary function of the reactor coolant system in a PWR is to: - correct
answer-Contain fission products that escape the fuel
