Very good points about safety, Rezwan. I’d like to add that in any conversation regarding safety, the questioner must specify the degree or specification (OSHA, IEEE, Mil-spec, etc), and preferably also specify the configuration(s) which are being asked about. Also, the person representing FF DPF should have a firm grasp that the water jacket covered with boron-10 and lead is designed specifically to reduce operating (not long-term) radiation to below background radiation levels.
Thus the question and response need not necessarily be about the LPPX envisionment for some remote and or military applications. Safety includes specifics.
