I heard that Pu238 has limited production capacity.
Apart from those widely discussed, I would be curious as of why these are rarely brought up:
My assumption is:
Apart from those widely discussed, I would be curious as of why these are rarely brought up:
- Pb210 is essentially Po210 with a longer half-life, which is more suitable for medium lifespan missions. How much Pb210 can be collected from a lead cooled reactor?
- Pu241 is essentially Am241, but it could give a slight power boost.
- Ac227 has a long decay chain which gives more (most?) power per atom. Any novel way for mass production?
- Cm242 is essentially Pu238, in addition to early power boost. Is it much harder to produce Pu238 this way?
- Pm147 has been discussed, but some sources give an unreasonably low power density (<1w/g) for its short half-life. Are they mistaken, or there is something I don't understand?
My assumption is:
- spent fission fuel can be reprocessed promptly,
- further decay of daughter isotopes contribute to total power output.
