This report documents the development and validation of the in-drift precipitates/salts (IDPS) process model. The IDPS process model is a geochemical model designed to predict the postclosure effects of evaporation and deliquescence on the chemical composition of water within the Engineered Barrier System (EBS) in support of the total system performance assessment (TSPA). Application of the model in support of TSPA is documented in Engineered Barrier System: Physical and Chemical Environment (BSC 2005 [DIRS 175083]).
The technical work plan (TWP) for this report is Technical Work Plan for: Revision of Model Reports for Near-Field and In-Drift Water Chemistry (SNL 2007 [DIRS 179287]). It calls for a revision of the previous version of the IDPS model report (BSC 2004 [DIRS 169863]) to update the thermodynamic database, augment the validation, reanalyze model uncertainty, and address several condition reports (CRs) (CR-6489, CR-6731, CR-6770, CR-7143, and CR-7721). Note that there is a small deviation from the TWP. In the TWP it notes that CR-6752 will be resolved in this document, by the update to the thermodynamic database. This is erroneous; CR-6752 does not apply to this thermodynamic database, thus it has not been addressed by this document.
