I know how it all works, I’m just saying you could give off more heat and less radiation if you designed it for heating rather than generating power, and having a separate heater item that can be turned on/off would probably be good in summer if you’re in a smaller vehicle/building.
The power generation one might have to be power only for balancing purposes.
NASA can -barely- manage to build these. They have too much plutonium stuff in the game as it is, largely because: 1. Environmentalist activists (as opposed to ordinary environmentalists, normal people) get completely hysterical whenever it comes to anything nuclear, and 2. They don’t make the stuff anymore.
What might be more realistic is coal. Easy to dig up across Appalachia, not running out anytime soon, relatively simple to set up machinery for. (Yes, I realize its bad for the environment; but its much more practical to do coal stuff then plutonium stuff AFTER A ZOMBIE APOCALYPSE.)
I never considered environmental activists as a reason not to include something in a game before >_> well, cataclysm isn’t based off of the US and such implementations might be compatible with the devs versions of historical accuracy. Maybe. I dunno.
RTGS are thermoelectric generators. As I understand it, they need a crazy high temperature difference between the poles to generate significant energy with present thermoelectric materials. Which is why RTGs are mostly restricted to satellites and space probes. The biggest one on earth listed on wiki weighs 2000 kg, and it generates 120 watts. You could run a lightbulb.
Now you’re talking. I’d rather need multiple minireactors running continously to run my tank than having to micromanage them with refuelling all the time. Plus currently they use up what seems like an unrealistic amount of plutonium.
Alternatively, you might consider basing it off of this, or similar:
You could probably get it crammed into something the size of a medium sized walk in closet or a very roomy bathroom for lower power models.
Speaking as an engineer, huge systems like nuclear reactors, chemical plants, etc are mostly piping and support systems like cooling or water treatment. Take that out of the equation and it gets a lot smaller.
Hell, wiki even mentions it.
"A water-cooled reactor is generally dwarfed by the cooling systems attached to it. Additional issues are that the core irradiates the water with neutrons causing the water and impurities dissolved in it to become radioactive and that the high-pressure piping in the primary side becomes embrittled and requires continual inspection and eventual replacement.
In contrast, a pebble-bed reactor is gas-cooled, sometimes at low pressures. The spaces between the pebbles form the “piping” in the core. Since there is no piping in the core and the coolant contains no hydrogen, embrittlement is not a failure concern. The preferred gas, helium, does not easily absorb neutrons or impurities. Therefore, compared to water, it is both more efficient and less likely to become radioactive."
