Coupled modelling of groundwater flow and hydrochemistry in the Sellafield area

UK Nirex Limited (Nirex) is investigating a site at Sellafield in Cumbria to assess its suitability as a host formation for a deep disposal facility for solid low and intermediate level radioactive waste. As part of the evaluation process, extensive characterization work has been performed. This characterization has included the acquisition of various types of information and data from the area around the site, and the use of this information in developing an understanding of the groundwater flow regime at Sellafield. Modelling the groundwater flow processes at the site is an important input to assessing the performance of the site as a host for a radioactive waste repository
