A survey of recent developments in the field of plutonium disposal by
the application of advanced nuclear systems, both critical and
subcritical. Current national R&D plans are summarized. The
actinide-fuelled critical reactors are associated with control problems,
since they tend to have a small delayed neutron fraction coupled with a
small Doppler effect and a positive void coefficient. Current thinking
is turning to accelerator-driven subcritical systems for the
transmutation of actinides.
The book's conclusion is that the various systems proposed are
technically feasible, even though not yet technically mature. The book
presents a unique summary and evaluation of all relevant possibilities
for burning surplus plutonium, presented by experts from a variety of
different disciplines and interests, including the defence
establishment. The obvious issue - the non-proliferation of nuclear
weapons - is vital, but the matter represents a complex technological
challenge that also requires an assessment in economic terms.
