Hall, T M; Kratzer, W K

The objective of this production test was to determine the decontamination effect of recirculating primary coolant in a shutdown 109-N cell at lower than normal pH while maintaining a high rate of feed and bleed. The procedure was applied to four of the 109-N cells during the period December 1973 through December 1974. Prior to and following each decontamination, radiation surveys were made at specified locations in order to measure any effects that might occur. Cell radiation readings were lower following each of the low pH flushes performed, although the change was rather insignificant. The main purpose of the low pH flush was to attempt to reduce the ''hot speck'' inventory in the primary coolant piping.
