nuclear power. Even if a leak should develop in
one of the welds, there would be no serious contamination
problem. Upon completion of the endurance
test, it should not be difficult to make a
thorough inspection of the parts - something that
could hardly be done after sustained operation at
high nuclear power.
At first thought, the ZPU might appear to delay
the program, but closer inspection indicates that
it may actually save a substantial amount of time,
because efforts to get it into operation can proceed
at full speed without the inevitable hazards, re-

straints, inhibitions, and hesitations that would
accompany high nuclear power operation. Work on
the CFRE can proceed at a inore deliberate pace,
and the mistakes disclosed by work on the ZPU
can be avoided. The degree to which the ZPU
will be a mockup of the CFRE will depend upon
the problems that develop in the course of the
component test work. It is hoped that a 104w
gas-fired furnace can be used, in place of one of
the two CFRE heat dumps, in making some heat
transfer tests on the fluoride-to-NaK heat exchanger
and in obtaining a temperature gradient
