Lone G, I work Nuclear too, why you quit? 
The Molykote 33 Light would be good for colder temps, as it's a NLGI-1 grease. That stuff is about $25 for a 5.3oz tube from Amazon. In the Nuclear world, we get it for $16.95/5.3oz tube. The problem is that it's in a tube and actuators usually have a zirk for greasing the nut and threaded rod. A cartridge makes that much easier!
I'd suggest Mobilgrease 28. It's what we use for all our Nuclear safety related applications and has an operating range of -65°F to 350°F.
Amazon product ASIN B00G3BTV5A
This stuff is great and works well through a wide temperature range. It performs like a NLGI-1/2 grease and maintains great resistance to getting stiff in the cold weather. This is a cartridge and would work in a grease gun for getting the zirks. We get 35# tubs for $420, not bad.

Alternately, I'd look for any NLGI-1 grease for sat actuators. Just try to maintain grease compatibility, though the results of mixing types wouldn't be cause for panic.
