Not being able (or willing) to turn turn nukes down or off to load-follow makes them sometimes as difficult to work with as intermittents. None in the GB grid load-follow, though one can AFAIK. And nukes need refuelling, so you need to fill in those generation gaps. And one of the last two big grid stumbles in the GB (UK) in the last ~20Y was caused by a big nuke (Sizewell B) tripping, so nukes can be big single points of failure too. Note: I am pro nukes in the mix, but nukes have difficult points too.
