Tank characterization report for single-shell tank 241-T-108

Preliminary tank characterization report for single-shell tank 241-TY-102: best-basis inventory

“…Tank 241-T-108 is expected to contain lClCW sludge as well as T1 salt cake (Agnew et ai. 1997a); however, the analytical results indicate that the tank 241-T-108 sample retrieved was primarily salt cake as evidenced by the high sodium concentration (223,000 pglg) reported for the composite (Baldwin 1996). Tank 241-T-109 contains only T1 salt cake generated from the 242-T Evaporator concentration of TBP and lClCW supernatants.…”

“…The analytical results were corrected to a silicon-free basis since diatomaceous earth (92 percent SiO,) was added to tank 241-TX-116 in November 1970, (Buckingham and Metz 1974). The analytical results are included in Table D3 Baldwin (1996 Horton (1977) Silicon-free basis due to the addition of diatomaceous earth to tank 241-TX-116 Agnew et al (1997a) e Calculated from the mean analyte concentrations for the three tanks.…”

“…The auger samples for tanks 241-T-108 and 241-T-109 are recent (1995) and the laboratory analyses of the samples should meet all Tri-Party Agreement requirements. Tank 241-T-108 is expected to contain 1C/CW sludge as well as T1 salt cake (Agnew et al 1997a), however, the analytical results indicate that the tank 241-T-108 sample retrieved was primarily salt cake as evidenced by the high sodium concentration (223,000 pglg) reported for the composite (Baldwin 1996). Tank 241-T-109 contains only T1 salt cake generated from the 242-T Evaporator concentration of TBP and lC/CW supernatants.…”

“…The analytical results were corrected to a silicon-free basis since diatomaceous earth (92 percent 30,) was added to tank 241-TX-116 in November 1970, (Buckingham and Metz 1974). The analytical results are included in Baldwin (1996) Horton (1977 Silica-free basis due to the addition of diatomaceous earth to this tank Since these analytes were not expected in this waste, the lower value was used instead of an average Predicted T1 salt cake radionuclides are decayed to January 1, 1994. The radionuclides for tanks 241-T-108, 241-T-109, and 241-TX-116 are reported as of the date analyzed, therefore, the average predicted.…”

Preliminary tank characterization report for single-shell tank 241-TX-112: Best-basis inventory

“…The auger samples for tanks 241-T-108 and 241-T-109 are more recent (1995) and laboratory analyses should meet all Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement) (Ecology et al 1994) requirements. Tank 241-T-108 is expected to contain lClCW sludge as well as T1 salt cake (Agnew et al 1997), however the analytical results indicate that the tank 241-T-108 sample retrieved was primarily salt cake as evidenced by the high sodium concentration (223,000 pglg) reported for the composite (Baldwin 1996).
