[ RadSafe ] Highly Enriched Fuel Reactors

[Jaro Franta]

The ignition assemblies in TWR are said to be about 14% U235 -- whereas
"highly enriched" starts at 20%.

The rest of the fuel is DU.

Hey All,
 
     So, with these TWR's and other highly enriched  fuel reactors, with
significant use of the fuel, the Cs-137, Sr-90 (i.e. Fission  Fragment)
radiation will build up quite quickly.  This will be a challenge  for Health
Physicists, Nuclear Engineers at such reactors.  Sounds like  fun.  Neutron
production will increase considerably also.
 
    Have a good week.

PS  I wonder if the bug zapper could be tuned up for tse tse  flies......
