- It would depend a lot on the particular technology. Something like a
- SNAP generator, packaged like for the space program, I'd buy. Something
- like a BWR sans concrete containment with melt down potential, I'd pass...
-
- Key Issues: 1) Structure such that physical abuse might make chunks
- of it, but not release {gas, liquid, or dust} that was radioactive. That
- is, no product that was subject to natural transport away from a crash site.
-
- 2) Structure such that a fire could not cause release of radioactives.
- That is, each 'chunk' from a crash site should be inert in a gasoline
- fire.
-
- 3) Fuel 'bundle' such that fuel recycling/reprocessing is 'easy'. I do
- not like the idea of burying partly used fuel bundles and calling it
- waste disposal (as we are planing now for commercial reactors). Make
- sure that the fuel bundles are re-processed to removed the long lived
- isotopes that make good fuel and only bury the short lived isotopes that
- are most radioactive but decay in the shortest time.
-
- 4) A 'nice to have': fuel bundle such that they are self sheilding.
- That is, if the {what, lead?} reactor shield is broken open in a crash
- the fuel elements are not lethal to a rescue worker... This implies
- either one heck of an interesting fuel element structure or a reaction
- that produces few/no neutrons and gammas... This may be an imposible
- constraint to meet in something that would fit in a car, ask the
- nuke engineers here, they know their stuff.
-
- Summary: If it doesn't pose a crash hazard, or a fuel handling/waste
- disposal hazard, I'd buy one.
-
- How large would a properly packaged 10 kW SNAP generator be?
-
- Any way to make a HTGR of a 20 kW size with fuel pellets that are,
- oh, marble sized,and with a fire proof chemistry?
