How is synchronous reactance for a cable defined?

The paper linked has the section 2.2 Determining the various short-circuit impedances.
Hopefully, that will answer your questions. If not, you need to be more specific about which rectance you mean.

Thanks :)

Interesting, I'd never heard that term before, "synchronous reactance", but there it is in the paper!

likewise, but then, am not into high power motors or generators for which this seems to apply toD

In my humble opinion, no synchronous reactance is defined for any part of a circuit except synchronous

machine: the ratio between EMF induced in the stator and short-circuit current at the same excitation level.
