Seems a bit on the overkill side of things. If practical factor demonstration is included then could be a somewhat useful tool. Spending 6 hours jawing about theoretical aspects with a job-coverage technician is a waste of time. Knowing that 1 joule/kg = 100 rem = 1Sv, 1Gy = 100 rad = 1 joule/kg, - yada yada accomplishes little. Showing that ya know when/why to hang a rope, when /why to establish an area and guard it, when to stop and call a RP supervisor, etc. is good use of time. Perhaps to kill some valuable time a quick drawing of the main feed system with all required valve positions to support a N2H4 addition could be used !! How do money matters work up there with the dollar and whatever is used up yonder not being on equal terms ?
