Fukushima Daiichi Nuclear Power Plant
Officials have thought about putting in or aerial dropping radiation killing boric acid, boronated plastic beads or boron carbide pellets into the spent fuel pools to absorb neutrons. France flew 95 tonnes of boron to Japan on 17 March 2011. Neutron are absorbed by boric acid, which has been injected into the reactor cores, but is unclear if boron was also included with the hose and fire truck water spraying of SFPs.
