Years ago I did some work for a UK firm called Powergen, I did similar for them (helped set up a new QC and trace-ability system etc), mostly coal and gas fired stations but nukes too. Also done some NDT myself, mostly magnetic/die-pen and ultrasonic but some Xray bombing.My last duty station was at a Naval Maintenance Facility in quality control making certain the the finished work package was complete with everything from chain of custody paperwork for welding rods to copies of the current eye tests for the welders and inspectors.
