Tank 41H Drained Saltcake Core Sample Analysis (HTF-E-03-033 - HTF-E-03-035)

PDF Version Also Available for Download.

Description

The Savannah River Site (SRS) has 49 carbon steel tanks that currently house 37 million gallons of High Level Waste (HLW) in the form of salt supernate, saltcake, and sludge solids. The saltcake in several of the SRS tanks was identified as candidates for the Low Curie Salt (LCS) process. LCS involves removing supernatant liquid, draining the saltcake interstitial liquid, and dissolving the remaining saltcake as a feed for the Saltstone Processing Facility. Three samples were received that correspond to approximately the top 26 inches of drained Tank 41H saltcake. The saltcake had an average bulk density of 1.91 g/mL. ... continued below

Description

The Savannah River Site (SRS) has 49 carbon steel tanks that currently house 37 million gallons of High Level Waste (HLW) in the form of salt supernate, saltcake, and sludge solids. The saltcake in several of the SRS tanks was identified as candidates for the Low Curie Salt (LCS) process. LCS involves removing supernatant liquid, draining the saltcake interstitial liquid, and dissolving the remaining saltcake as a feed for the Saltstone Processing Facility. Three samples were received that correspond to approximately the top 26 inches of drained Tank 41H saltcake. The saltcake had an average bulk density of 1.91 g/mL. Two of the samples were extracted with 30 psi N2, the test on the upper sample was stopped after one week, and the other sample continued for one month. The bulk of the salt was light in color, hard packed, and had 3 to 4 wt per cent water. Being drained saltcake, it had relatively small amounts of NaOH and NaNO2. Combining the data from both tests in a conservative manner, the dissolution of the top 26 inches of Tank 41H saltcake may yield a 6 MNa+ solution with as high as 0.10 Ci/gal of 137Cs.
