Attached to this report is a letter containing pertinent information by P. R. Matthews, dated Jan. 20, 1958. 2p. The investigation of a magnetic- magnesia or magnetiteMg axial flow bed filter for high-temperature purification of S3G/S4G primary coolant included the following studies: foue out-of-pile tests of the hot bed filter, determination of the solubility of MgO up to 626 deg F in a stainless steel autoclave, two in-pile tests at the MTR site, and comparison of hot bed filter performance with expected ion exchange performance in S3G. The following conclusions are drawn: neither MgO nor Mg metal is suitable for maintaining high pH conditions in primary coolant water at S3G operating temperatures; except for maintaining the S3G reference pH, use of magnetite alone in the S3G coolant demineralizer would provide the requisite purification for normal operation of the plant; fission product removal was not conclusively analyzed, but the indications are that the bed filter does not perform as well as ion exchange.
