What is the smallest size a nuclear reactor could be?

Looking to see if a atomic reactor could break faith with made to fit in 4 cubic feet or less

Well they manage to fit one into a nuclear submarine - it's just the lead shielding that takes up the space - but I suspect they are a bit larger than 4 cubic feet - perhaps nearer a cubic metre.

No it couldn't You need a certain amount of uranium before a reaction is possible. Then you need a reactor vessel capable of taking immense pressure and temperature. Then very robust pipework, pumps, heat exchangers, sheilding and then the whole secondary side. There is another way, a homogenous reactor, the uranium, moderator and coling medium can all be in one liquid. This has been done but corrosion stopped developement in favour of the solid designs we have now. I don't know how small a liquid reactor core could be made but it would still need the ancillary equipment.
