Characterization modeling to support the hanford 618-10 and 618-11 burial grounds remediation design solution: two differing approaches with similar results

Two different approaches were applied to characterization modeling of the waste in the 618-10 and 618-11 burial grounds. The results were compared and it was found that the independent approaches validate each other. The 618-10 and 618-11 burial grounds, located on the Hanford site in Washington state, received primarily radioactive laboratory waste in the 1950's and 60's; however, disposal records from burial activities have since been destroyed. North Wind Inc. (NWI) is completing a technology demonstration project, funded by DOE Headquarters to develop methodology for remediation of the vertical pipe units and develop supporting documentation. Washington Closure Hanford (WCH) is developing a design solution for remediation of the 618-10 and 618-11 burial grounds, including the development of a characterization model and estimates of radioactivity and waste volumes present. Each company independently developed their characterization models and radionuclide inventories, using a different methodology; however, the results of each model revealed only a two to five percent difference, which is significant given the complexity of the waste matrices, the high dose rates of the waste when disposed, and relatively high levels of transuranic radionuclides projected.
