TV talk shows and press stories immediately indulged into obviously
fissionable narratives and accounts of the stated and even 'unstated' reasons behind Mr.
At the time of such an accident the pump sprays boric acid water into the vessel and eliminates contamination of the

Unlike uranium, which contains only 0.7 percent
fissionable material, thorium doesn't require enrichment to be used in nuclear reactors.
Khan remains a hero to many of his compatriots, even though the technology that has allowed Pakistan to produce the
fissionable material needed for a bomb was stolen rather than developed.
Pearce describes the huge quantities of energy required to obtain
fissionable uranium isotopes out of uranium ore, which contains only a fraction of a percent to a few percent uranium oxide ([U.sub.3][0.sub.8]).
In the years after 1939, the last theoretical uncertainties about whether nuclear weapons were even possible had basically been eliminated, but there was great doubt on all sides as to whether the sheer task of generating
fissionable uranium-235, or plutonium, was industrially feasible.
Recycling proponents want ultimately to build a fleet of fast neutron reactors that could consume the plutonium and other
fissionable material.
"While it is true that the plutonium in recycled nuclear fuel is
fissionable, no country in the world has ever made a nuclear weapon out of low-grade plutonium from recycled high burn-up nuclear fuel.
