Nuclear power plants rely on which of the following reactions to generate energy?
Fusion
Fission
Nuclear power uses ____ for fuel.
adamantine
stoat
uranium
hydrogen
Uranium-235 is considered ideal for use in nuclear reactors because
it is a widely distributed resource.
it is a stable isotope.
it has a high EROEI (efficiency rating).
it produces minimal radioactive waste.
it is highly fissionable.
Nuclear energy uses (a) to rotate the turbine on a generator. (one word)
What is the difference between a nuclear bomb and a nuclear power plant?
Bomb releases energy all at once, power plant release is slow and controlled.
Bombs use fusion while power plants use fission
Power plant releases more energy, faster.
A different chemical reaction is taking place
What controls the reaction within a nuclear reactor?
Rods made of neutron absorbing material
Moderator made of neutron emitting material
Containment building made of steel, lead, and concrete
Condenser chamber at the end of the second circuit
Of the three most pre-eminent nuclear disasters known around the world, what was the common theme across the failed systems?
Failure of cooling systems
Explosion from fission
Earthquakes and tsunamis
Deaths from radiation
Which is NOT a disadvantage of nuclear energy?
Nuclear power plants are very expensive to build.
Acquiring nuclear fuel requires mining.
Radioactive waste can be dangerous for thousands of years.
Air pollution occurs while the nuclear power plant is active.
Nuclear meltdowns can lead to catastrophic consequences.
Which is NOT a disadvantage of using nuclear energy? (were you paying attention to the last question?)
Radioactive waste disposal
Reactor accidents or terrorism
The amount of CO2 released by the reactors
Mining for uranium
How is nuclear waste currently stored?
Waste is stored on site.
Waste is contained in drums and stored on the ocean floor.
Waste is sent into space on a rocket.
Waste is stored in a geologically stable site away from human habitation.
The time needed for half of a radioactive sample to decay is called its __________.
decay period
fission period
transmutation time
half-life
