That was the conclusion of the Idaho National Engineering Laboratory, which several years ago conducted a study of all the nuclear reactors in the United States. Merle Griebenow, former BNCT director at the laboratory and president of Neutron Technology since 1992, says Georgia Tech's reactor can easily be converted to provide the best epithermal neutron beam in the world for the treatment of cancer. Essentially it means inserting a filter consisting of aluminum sheets between the core and the vessel, spaced to allow heavy-water to circulate between the gaps. The face of Georgia Tech's reactor core has a large beam port to effectively treat a patient, Griebenow says. You don't have to cut any holes in the reactor vessel, and there is no big engineering challenge.
Conversion is kind of a no-brainer.
