Title: 224-T TRUSAF Building upgrade

An examination of the process scheme for handling present and future 231 Building supernatant solutions is necessary to forecast the effects of placing one of the processing facilities (224B) in a standby status and to ascertain if rescheduling of any of the supernatant solutions to 202S will be necessary. The examination indicates the 231 Building process supernates and cell cleanouts together with the 221, 224T Buildings acid washes and the 234-5 Building returns can be processed through the 224 T Building as additions to regular runs or master recycle runs when T Plant is processing as much as 41.6 tons/monthmore » of 600 MWD/T material and S Plant is processing 120 tons/month of similar material. The processing rate through, 224 T Building to satisfy these conditions is seventy-six runs per month. This total is divided into 63 regular runs plus 13 meter master recycle runs. The number of master recycle runs are primarily dependent upon the T Plant rate in as much as only one master recycle is directly required for each 35 tons processed through S Plant.« less

The Isolation Process, contained in the 231 Building, has an operational cost of approximately $35,000 per month. The location of this process in the 224-T Building would result in lower manpower requirements and effect an estimated savings of $5,000 per month. This report details study made to determine the feasibility and approximate cost for installing this process in 224-T.

Since the issuance of HW-17398, Separations Section Operating Standards - Part I relating to the Bismuth Phosphate Process on March 1, 1951, several changes in the process have been found desirable and have been reduced to practice. This document presents these changes.
