As I know, the sodium is used for heat transfer for some

However, the coolant of choice for large electric generators is
hydrogen gas since it carries away about 5-times as much heat as air.

Their answer after a
lot of research was to make the exhaust valve stem hollow and fill it
with Sodium with significantly good results.
Sodium valves were used in a lot of internal combustion engines, not
just Nortons! The idea is that the liquid sodium inside the valve
stem
would actually flow, thus transferring heat by convection away from
the
valve face and through the valve guide to the cylinder head. In the
case of coils, there's no obvious analogue for the cylinder head to
dissipate heat.
