of support activities required both to provide raw fuel and
to recover and recycle the uranium and plutonium make up
wnat is known as the nuclear fuel cycle.
The AEC has
projected that over 4 million megawatts of nuclear capacity
will be installed between 1970 and 2020.
Over the lifetimes
of these plants this installed capacity could result ina
cumulative flow of approximately 200 million kilograms of
plutonium throush the nuclear fuel cycle.
