Pu from nuclear weapons stockpiles for making mixed oxide fuel (MOX), which is now being redirected to become fuel for nuclear reactors.

This dilution, also called downblending, means that any nation or group that acquired the finished fuel would have to repeat the very expensive and complex chemical separation of uranium and plutonium process before assembling a weapon.

The half life of carbon 14 is about 5,000 years, so it becomes increasingly difficult to detect at time much longer than this.

Geologists use radiometric dating employing other elements that decay more slowly such as uranium/lead and potassium/argon for rocks, particularly very old rocks. Carbon-14 has a short half-life and is normally only used by archaeologists or anyone working on sediments less than 50,000 years old. Scientists used many different isotopes for dating rocks in Radiometric Dating, uranium/lead, potassium/argon and others are used.

However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239.

It also requires other things, such as that the elements involved do not wash away in water or escape as gas in an unknown manner.

Around 99.284% of natural uranium's mass is uranium-238, which has a half-life of 1.41 By December 2005, the only breeder reactor producing power was the 600-megawatt BN-600 reactor at the Beloyarsk Nuclear Power Station in Russia.

Russia has planned to build another unit, BN-800, at the Beloyarsk nuclear power plant.

Because depleted uranium has no critical mass, it can be added to thermonuclear bombs in almost unlimited quantity.

The Soviet Union's test of the "Tsar Bomba" in 1961 produced "only" 50 megatons of explosive power, over 90% of which came from fusion, because the U been used instead, the yield of the "Tsar Bomba" could have been well-above 100 megatons, and it would have produced nuclear fallout equivalent to one third of the global total that had been produced up to that time.

The breeder reactor as its name implies creates even larger quantities of Pu than the fission nuclear reactor.
