The potentialities of unfiltered Columbia River water as a pile coolant have been discussed in a recent survey of the available information on the subject. The survey report points out the gains which the use of unfiltered water offers, and proposes a logical framework of treatment by chemical additives which appears to have a reasonable probability of successfully developing a far less expensive pile coolant. A comprehensive testing program is now being initiated to obtain the required experimental information concerning the effects of unfiltered water on corrosion, film formation, and effluent activity. The purpose of this report is to outline the range of variables to be studied; to discuss the various experimental techniques to be used; and to establish the anticipated scheduling of the several phases of the program.

Summary: "The quantity of water adsorbed by graphite at various relative pressures has been determined and the data are presented in graphical and tabular form."
