Loop L-2-19 operated in HB-2 of the WTR for 1148.9 hours of circulation and 2705 Mwhr of LITR operation. The solution contained 0.17 m enriched UO/sub 2/ SO/sub 4/, 0.02 m CuSO/sub 4/, 0.12 m excess H/sub 2/SO/sub 4/, and 0.20 m Li/sub 2/SO/sub 4/ in H /.sub 2/O, The main stream was 280 deg C and the pressurizer 295 deg C. There was no unusual difficulty during loop operation. A revised loop sample procedure gave better flushing of the sample lines. Four valves failed due to severe corrosion and fracturing of the 420 SS stems. 1-131 was not detected in a sample of gas taken from the gas hold-up tank. The run was terminated when the circulating pump failed. (auth)
