Additional protection provided with engineered barrier systems can overcome major concerns the public has with shallow land burial: subsidence; percolating ground waters; radionuclide migration; and the vulnerability of shallow trenches to intrusion. The presence of a variety of engineered barriers to restrict water movement, retain radionuclides and to prevent plant animal or human intrusion leads to significant changes to input data for performance assessment models. Several programs which are underway to more accurately predict the long-term performance of engineered barriers for low-level waste will be described. %0Conference %NAECL-9611; CONF-870859-;Other: ON: DE92620961; TRN: CA9200070026372 %1 %CCanada %Rhttps://doi.org/ Other: ON: DE92620961; TRN: CA9200070026372 INIS %GEnglish
