- TL;DR Summary
- capturing only a percentage of the fusion neutrons in the thermal blanket to generate energy.

Regarding electricity generation from a fusion reactor:

I can't seem to find any discussion about the percentage of fusion product neutrons that can be realistically caught in the thermal blanket to utilise the energy they carry from the fusion reaction.

The neutrons from fusion have to be slowed to change their kinetic energy into heat so electrical power can be generated at a steam turbine. Thermal blanket may be the wrong term but I think it's obvious what my enquiry concerns.

So how comprehensive is the coverage of said ' thermal blanket' and what percentage of fusion energy is expected to be lost by neutrons that escape through the areas not covered by this thermal blanket ?

I can't imagine it is anywhere even close to 100% of the fusion product neutrons being caught in the "thermal blanket" to extract the KE they carry.

Nevermind catching the energy from neutrons that have been used to produce more tritium.
