Statement on Columbia River Problem (Dictated by Dr. Bugher at Rochester, although will not be used at this time) In recent meetings the Committee has received extensive information from the Division of Production as well as from members of the scientific staff of the Hanford Works concerning the induction of small amounts of radioisotopes in the reactor cooling water which is returned to the Columbia River. The small significant isotope still appears to be Phosphorus-32, which is selectively concentrated in some of the biological systems of the Columbia River so that detectable amounts appear in the whitefish. With the projected power increase it must be anticipated concentrations of the various radioisotopes will be still further increased. While we do not feel that there is immediate threat to the public health we do recognize that there is a public relations problem of potential gravity. We concur therefore in tkplan suggested by the Division of Production to initiate extended studies which, it is hoped, would lead to substantial reduction particularly in the amount of P-32 produced. The study would involve the exploration of the use of aluminum nitrate instead of aluminum sulfate for water purification and an examination of the ways for reducing the formation of films adherent to the surfzi~eof the cooling system of the reactor. It is our understanding tests will also be needed on possible methods Of removing isotopes from the coolant water after it leaves the reactor. The scientific and engineering studies must necessarily be coorelated with cost estimates before final decisions can be reached concerning the methods to be used.
