How is a nuclear power plant different from an atomic bomb quizlet?

How is a nuclear power plant different from an atomic bomb? A nuclear power plant has controlled chain reactions when energy is released. Atomic bombs are uncontrolled reactions that result in explosions.

What type of nuclear reactions occur in nuclear bombs?

Nuclear Weaponry A nuclear weapon can either undergo a nuclear fission reaction (atomic bomb) or a nuclear fusion reaction (H bomb or thermonuclear bomb). The first nuclear weapons built underwent pure nuclear fission. Uranium-235 and Plutonium-239 were the most common fissile isotopes used.

How do nuclear reactors keep nuclear chain reactions from getting explosive quizlet?

How do nuclear reactors keep nuclear chain reactions from getting explosive? The control rods absorb the neutrons and slow down the chain reaction.

What 2 chemicals are in the atomic bomb?

The isotopes uranium-235 and plutonium-239 were selected by the atomic scientists because they readily undergo fission. Fission occurs when a neutron strikes the nucleus of either isotope, splitting the nucleus into fragments and releasing a tremendous amount of energy.

Which type of reaction is used in nuclear reactors?

Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity.

Which type of nuclear reactions are used in atomic bombs quizlet?

In a nuclear chain reaction, the amount of energy released increases rapidly with each step in the chain. If a nuclear chain reaction isn’t controlled, the released energy causes a huge explosion. The explosion of an atomic bomb is an example of an uncontrolled nuclear fission reaction.

What is stronger nuclear or atomic bomb?

During World War Two, “atomic bomb” usually meant a bomb that relies on fission, or the splitting of heavy nuclei into smaller units, releasing energy. The action happens in the nucleus of the atom, so it is probably more accurate to call these “nuclear bombs.” These weapons are more powerful than fission weapons.

How are nuclear reactors different from nuclear bombs?

“Commercial reactors have just a few percent fissile material in them, and bombs have more than 90 percent,” Makhijani said. Those chain reactions aren’t slowed by uranium 238 or control rods. At least one neutron from each fission reaction is likely to cause another fission to occur.

How are nuclear fission reactions used in nuclear power plants?

Nuclear fission reactions are done to generate electricity at nuclear power plants. Nuclear power plants use nuclear fission reactions to generate electricity and the fuel used for this purpose is uranium-235. In a nuclear power plant, a fission reaction is carried out in a steel pressure vessel, and inside is a nuclear reactor.

What are the two types of nuclear reactions?

There are two types of nuclear reaction. They are: The heavy nucleus of radioactive atoms like uranium, plutonium, or thorium is bombarded with low-energy neutrons which split the nucleus into smaller nuclei. This process is called nuclear fission.

What happens when a nuclear reactor is turned off?

The rate of chain reactions is controlled by rods of material that soak up the neutrons, and slow that chain of fission reactions. (When the machine is turned off and idle, it continues producing some excess heat through radioactive decay, which has been the source of problems at Japan’s Fukushima plant.)
