System and method to control migration of contaminates within a water table

摘要: System and Method is described that controls the release of contaminated water by rapidly freezing ground water, including salt which permeates area underneath a contamination source, so resulting ice lens mitigates extent to radioactive released into environment. An aperture in containment allows dispersal dilution contaminates allowing from outside, and/or removing area. The variable may be physical valve or preferably an opening shield size controlled thawing portions shield.
