Model Results Of The Draining Of Tank 25 Interstial Liquid

PDF Version Also Available for Download.

Description

SRNL was tasked to simulate the draining of interstitial liquid from Tank 25 saltcake which is scheduled to take place in 2005. The salt processing plan baseline identifies a target of 135,000 gallons of interstitial liquid to be removed from Tank 25. Due to the uncertainty of the Tank 25 material properties and conditions, several cases were modeled varying the saltcake and interstitial liquid properties. The cases present a wide range of performance. The nominal baseline, case 1, removed the 135,000 gallons in approximately 1,030 hours of pump operation. The cases with optimal drain characteristics (high intrinsic permeability, high temp.) ... continued below

Description

SRNL was tasked to simulate the draining of interstitial liquid from Tank 25 saltcake which is scheduled to take place in 2005. The salt processing plan baseline identifies a target of 135,000 gallons of interstitial liquid to be removed from Tank 25. Due to the uncertainty of the Tank 25 material properties and conditions, several cases were modeled varying the saltcake and interstitial liquid properties. The cases present a wide range of performance. The nominal baseline, case 1, removed the 135,000 gallons in approximately 1,030 hours of pump operation. The cases with optimal drain characteristics (high intrinsic permeability, high temp.) drain the 135,000 gallons in less time. Those with less favorable drain conditions did not approach the 135,000 gallons in a reasonable amount of time. Common to all cases unable to achieve the target volume was the low temperature at which they were run, 30 C (the lowest modeled), though there were additional contributing factors. A summary of the results are shown in Table 1.
