fissionable

Well, the only problem was, he had no what you call "fissionable" materials.

Do we know if there's a way he could get his hands on fissionable material?

The fissionable material defined by the preceding paragraph should be reported to the Atomic Energy Council once every half-year.

But in nuclear reactors, which contain far less fissionable material, the chain reaction and the release of energy are carefully controlled.

In a hole in the center of this system is placed a subcritical sphere of fissionable material.

The reaction is slowed by a combination of depletion of the fissionable material and expansion of the core .

Fissionable material used in a nuclear reactor .

the commonest isotope of uranium; it is not fissionable but when irradiated with neutrons it produces fissionable plutonium 239.

An atomic bomb uses conventional explosives to slam together two lumps of fissionable material, usually uranium-235 or plutonium-239.

It can be applied to complicated critical calulation for the fissionable material , such as critical calulation for duplex non-even system.

it may be fissionable material which, in a nuclear reactor, will heat water to produce steam;
