On March 14th Ceradyne, Inc. had a press release concerning Fukushima nuclear reactor. In the statement they offer to supply boron carbide to help control and contain the radiation of the damaged reactor. Boron has the unique ability of absorbing neutrons. The plan would be to use boron carbide rod to control the radiation leaving. Another use for boron carbide would be to enriched boric acid. The acid would then be dumped into the reactors coolant system causing a reduction in nuclear fission and hopefully reduce the amount of radiation leaving.
Lastly I wish to express my concerns and sympathy for all those effected by this disaster.
