Nope. Just need to get a nuclear regulatory commission license and you are all set. Will probably set you back $100,000,000 and there is a lot of training and emergency drills required to keep your license and avoid nasty fines. You need to establish the safety basis against accidents, such as, demonstrate that the public radiation doses limits will not be exceeded if a 747 crashes into your C14 power supply.

There is nothing to “drill” for with a decay cell.
There are no moving parts.
No emergencies either, unless someone bombs it from the air. Its just a container full of radio-active debris and thermocouples.
