Neutrinos and Arms Control Thinking Big about Detection of Neutrinos from Reactors at Long Distances

We discuss a somewhat futuristic plan for a world network of enormous neutrino detec tors which may be employed for monitoring the activity of all reactors on earth Three or more cubic kilometer size instruments with sensitivity down to about MeV placed in the deep oceans or possibly lakes can record the electron anti neutrino uxes from reactors no matter where they reside Using known power levels from the roughly operating reactors one can detect and monitor any new reactor in particular one which may be producing illicit nuclear weapons material Such a signal cannot be hidden or jammed and via tomography may be located to a precision of order kilometers over a
