Best Answer

To set off a fission reaction (the reaction that occurs in a nuclear reactor), a person must first pump a neutron into a heavy nucleus. So if a neutron is pumped into a uranium or plutonium nucleus capable of undergoing fission, the nucleus splits in two, and releases more neutrons, which hit more nuclei, which in turn send out even more neutrons, thus setting off a chain reaction where every time a neutron hits a nucleus, the nucleus splits in two and sends out more neutrons.

What does plutonium react with and wont react with?

Plutonium react with the majority of nonmetals; plutonium doesn't react with noble gases. Plutonium can form alloys with other metals.


Can plutonium mix ti make another element?

- Plutonium can react with other elements to form chemical compounds- Plutonium can be transformed in other elements by nuclear reactions or radioactive decay


How is uranium made in to energy we can use?

Uranium-235 react with thermal neutrons in a nuclear reaction called fission. The enormous energy released by the nuclear fission can be transformed in electricity and heat in nuclear reactors.


Does plutonium react with anything?

Plutonium can react with the majority of other nonmetals.


Why don't the pellets with uranium oxide start to react during the enrichment process?

1. The material for enrichment is the uranium hexafluoride (UF6) not uranium dioxide pellets. 2. For a nuclear fission and and a nuclear chain reaction we need thermal neutrons.


Why would a fusion reactor produce less radioactive waste than a fission reactor?

In my understanding, this is because a fusion reactor reacts deuterium to produce helium, which is not radioactive, whereas a fission uses uranium or plutonium, for example, which may react to form various radioactive isotopes. A fusion reactor may contain small quantities of tritium, in which case a radioactive isotope of hydrogen may be produced, but given that the majority of reactions occurring involve solely the deuterium, there is less radioactive waste produced.
