Please, read the thread carefully. The point is that with VHTRs you don't need the usual electrolysis to split water into hydrogen and oxygen. Instead you can use high temperatures produced by a reactor to power conversion directly, th

For HB you need pressure of 250-350 bars, while existing PWRs routinely work with 150 bars of coolant pressure. I assume it's possible to produce hydrogen with the necessary pressure using VHTRs, i.e. you would get hydrogen already pre

The Haber-Bosch process used in ammonia production is done at high temperatures (400-500 °C), so you can use "hot" hydrogen to power it (i.e. to heat input nitrogen) and maybe even extract some of leftover energy in produced ammon

With very-high-temperature reactors (one of potential paths for Generation IV reactors) you can produce hydrogen using reactor heat directly, bypassing the electricity conversion step, thus significantly improving efficiency of the process.

>Then you're reconfiguring a breeder into a burner. You don't have both at the same time. My point was what the same fast reactor can be used as both breeder and burner without specifying "at the same time". And I am

What? Different blankets simply produce different results. Load blanket with mostly U238, irradiate it with fast neutron flux for a bit, and finally radio-chemically process the result to extract useful fission elements for new fuel rods to

AFAIK most fast-neutron reactors can be used as both burners and breeders depending on loaded blanket. The same neutron flux can be used to split actinides and transform U238. The planned BREST reactor is a good example here: https:/&

I was answering the GP question with a rough estimate based on simplistic calculations, not building a full blown business model for the reactor in question.

This is why I wrote that realistically it will be closer to 15-20 years. There are other factors which are not considered in my simplistic calculation.

Note that in my comment $25 MWh was only about OPEX (fuel cost, personnel, etc.), while your cost includes CAPEX, interest, and probably payments to a decommission fund. The number is based on 2013 estimate of the US Department of Energy (I

by fuoqi 5y ago
Assuming electricity cost $110 MWh and OPEX of the reactor on the level of $25 MWh with 90% capacity factor without accounting for interest (since it's near zero nowadays), it will take slightly more than 10 years for the reactor to pa
