Plutonium
Could it also include Neptunium? This I believe is also man made.
No, they don't. All Pakistan nuclear power reactors are imported from outside.
Yes, plutonium can be produced in a commercial nuclear reactor from uranium through a process called irradiation. When uranium-238 absorbs a neutron, it is transmuted into plutonium-239. This production of plutonium is a byproduct of the fission process in traditional nuclear reactors.
They all use nuclear fission
No, nuclear fission operates all nuclear reactors. If they are power plant reactors it is used to generate electricity.
No, plutonium is obtained in all the types of nuclear reactors.
I have put a link to the Wikipedia page, "List of nuclear reactors," below. It seems to be pretty good, and includes some reactors that are not in nuclear plants, such as research reactors.
All power producing reactors are either PWR or BWR types
Absolutely, this occurs naturally all the time in radioactive decay and in fusion in stars and supernovae as well as artificially in particle accelerators, nuclear reactors, and nuclear bombs.
nuclear reactors are not very safe at all. the nuclear energy buisness basically went to crap after the three mile island accident, because people decided the risks outweigh the benefits
All countries that have nuclear reactors have nuclear waste and it is always a problem, though a manageable one.
Nuclear power plants, submarines and aircraft carriers propelled by nuclear reactors. In the future, may be all sort of vehicles could have small and very protected nuclear reactors instead of today's fuel.
See www.nrc.gov, there is a list of all states with nuclear power reactors.
