one that captures neutrons for example (but you must have a neutron source)

Quoted By:

Considering a reactor produces 6 TWh of electricity per year (roughly 18 TWh of heat).
That is 7.0E+16 J per year.
The loss of mass is Dm = E / c^2 = 7.0E16 / (3.0E+8)^2 = 0.8 kg

This seems measurable

in fuel you always have a net positive neutron production, that is what the fuel is for. Therefore all fuel lose mass
