Tank 241-BY-104 rotary core sampling and analysis plan

Tank Characterization Report for Single Shell Tank (SST) 241-TX-118

“…Under the direction of the Tank 241-IX-I18 Push Mode Core Sampling and Analysis Plan (Benar 1997) AI1 results were 2 percent of the lower flammability limit (LFL) or less. The results from the combustible gas meter readings are reported in the ZH SnzrData Standard Report.…”

“…Two core samples were requested to be taken from tank 241-TX-118 (Benar 1997 andMcCain 1998). Seven segments per core were expected from the tank to obtain a full core profile.…”

“…The data obtained from the core sampling events were collected and analyzed with approved and recognized sampling and laboratory procedures and in accordance with the sampling and analysis plans (Benar 1997 andMcCain 1998). The laboratory procedures for the core sample analysis can be found in the Analytical Methoak and Procedures Standard Report.…”

Test procedures and instructions for Hanford tank waste supernatant cesium removal

“…Approximately four and one-half liters of dre.inable Double-Shell Slurry Feed (DSSF) supernatant liquor from Hanford Tank 241-AW-101 will be acquired through the sampling efforts of the TWRS Characterization Project at Hanford (Benar 1996) and will be placed in the hot cell with the test apparatus. The DSSF supernatant liquor will be diluted with water to a concentration target of five molar sodium, mixed, settled, decanted, and centrifuged to remove particles, and then placed in the feed tank(s) to be used as the feed for the column flow tests.…”

“…The 'waste feed will be composed of a composite of drainahle supernatant liquor from samples taken from Hanford Double-Shell tank 241-AW-101 during the 1996 core drilling operations which commenced in February 1996 (Benar 1996). The waste feed is of approximately 10 M Na+ and 5 M OH-.…”
