There are literally thousands of Star Wars fans who would kill for this job.
Yep people working in the industry tend to die as well. A company i worked for repaired the robot/manipulator arms at Sellafield here in Cumbria. The arm was taken out the pot and decontaminated to work on, whilst one of our guys was working on it a drip of grease landed on him off one of the arm joints. Sadly he is is no longer with us. He got irradiated by the grease and was gone in 24 months.
We also have the site of Windscale where Britain had its first nuclear disaster https://en.wikipedia.org/wiki/Windscale_fire.

I cant see a laser being used much to cut up reactor parts, the risk of causing a fire and the knock of effect of discharge into the environment/atmosphere would outweigh the benefits. Probably why the clip is the companies promo video.
