So you are going to put the fissile material which operates at muti megawatts in a briefcase and carry it away?

Disregarding the health and safety issues of the briefcase carrier the briefcase is sure to turn into a pile of molten radioactive sludge very quickly.



the multi-megawatts comes from the nuclear chain reaction. presumably any package used to transport fuel would prevent criticality.


I believe the 1% of nominal output is a reasonable ballpark for cooling requirements after a reactor is shut down. 1% of 1MW is still 10kW. You probably don't want to transport that in a briefcase.

Nah those have already existed for a long time: https://en.wikipedia.org/wiki/Radioisotope_thermoelectric_ge...


Yes, of course. Below critical mass for chain reaction, fissile material deteriorates fairly quickly into stable isotopes.
