A nuclear power plant has controlled chain reactions when energy is released. Atomic bombs are uncontrolled reactions that result in explosions. … They contain uranium dioxide that undergoes controlled fission in a nuclear reactor.
How is a nuclear power plant different from an atomic bomb?
One main difference between the two is that the fission events in a reactor are monitored and controlled closely. An atom bomb is an uncontrolled fission chain reaction, that releases exorbitant amounts of energy quickly. The design of a nuclear reactor includes control rods.
How is the rate of fission controlled in a nuclear power plant quizlet?
Metal fuel rods must be bombarded with neutrons in order to start a chain reaction. How can the rate of fission in a reactor be controlled? The rate of fission in a reactor can be controlled by control rods. Control rods absorb neutrons and put them between the fuel rods.
What is the main source of fuel for nuclear power quizlet?
The fuel source that nuclear power plants use is called uranium. They obtain this fuel source is mined from the western United States. How is the heat given off during nuclear fission used? The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the turbine blades.
Where do most experts think we will store nuclear waste in the long term?
Commercial energy generation produces the majority of nuclear waste in the U.S., which remains stored above ground near each of the 99 commercial nuclear reactors scattered around the country. Nuclear waste is stored in pools to cool for many years, and some is moved to above-ground concrete casks.
What happens if a nuclear power plant explodes?
What happens when there is a nuclear power plant accident? A nuclear power plant uses uranium fuel to produce steam for generating electricity. … If a nuclear power plant accident occurs, heat and pressure build up, and the steam, along with the radioactive materials, may be released.
Can nuclear fuel be weaponized?
Weapons-grade uranium and plutonium surplus to military requirements in the USA and Russia is being made available for use as civil fuel. Weapons-grade uranium is highly enriched, to over 90% U-235 (the fissile isotope).
What is the purpose of a chain reaction in a nuclear power plant?
A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats. The process may be controlled (nuclear power) or uncontrolled (nuclear weapons).
What are the problems associated with nuclear power plant?
Nuclear energy produces radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
What is an advantage of using nuclear power?
The advantages of nuclear energy are that it produces low-cost energy, it is reliable, it releases zero carbon emissions, there is a promising future for nuclear technology, and it has a high energy density.
What happened at the Chernobyl nuclear power plant in 1986 quizlet?
The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the atmosphere and downwind – some 5200 PBq (I-131 eq).
