One benefit of having mutiple small power stations as opposed to one mega- power station is that it makes it easier to use the waste heat for some useful purpose.

I don’t think there is much waste heat. The heat is hoarded carefully, because it is needed in the plasma to keep things hopping! In fact, the whole electron beam output is deliberately fed back into the plasma to keep it heated. Of course, an overall operating efficiency of even 85 or 90% does suggest the other 10% is ending up as thermal waste, the famous Laws being what they are … 😉
Keep in mind that this is a SMALL reactor. The actual operating core is measured in inches, not feet, yards, meters.
