Apparently the reactors were shut down automatically as soon as seismic activity registered on the instruments, so there are probably no neutrons to speak of. The heat is largely due to the decay of radioisotopes, and having boron in the water wouldn't make any difference, though it does surprise me that there is no gravity feed for the cooling water. However one has to wonder whether the pumps were electric, and shutting down the reactors resulted in no power for the pumps....? Did the earthquake destroy the grid connection too? >Can someone here explain why nuclear sites are not required to have a >gravity feed tank filled with borated water ready to flood reactors? >What am I missing here. > >Dennis > > > Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
