Beta or Alpha emitter nuclear fuel cycle?

Click For Summary
SUMMARY

The forum discussion centers on the potential of utilizing beta or alpha emitting isotopes in nuclear fuel cycles, specifically uranium or thorium, to harness energy through direct energy conversion methods. Participants highlight the possibility of reducing power plant size and eliminating the need for steam turbines. Various methods such as betavoltaics and radioisotope thermoelectric generators are mentioned, but their inefficiencies in low power applications are noted. The discussion also raises questions about the efficiency of nuclear fusion based on aneutronic reactions.

Do exist some proposed nuclear fuel cycle in which uranium or thorium whoud be first converted in some beta or alpha emitting isotope and after energy whould be harnessed with direct energy conversion methods?Possibly, it could reduce size of power plant and make steam turbine unnecessary.
 
Engineering news on Phys.org
There are various ways of harnessing nuclear energy without a steam cycle, e.g. betavoltaics, radioisotope thermoelectric generators, etc. But these are all very inefficient and limited to low power applications.
 
Could you explan,why betavoltaics is very inefficient?It suppose to be efficient because energy could be converted directly,with help of MHD generator.
Do you think that nuclear fusion based on aneutronic reactions is also going to be unefficient?
