why didnt you start off with that. At Fukushima daiichi there is a lot of surface water that flows INTO the facility (An inch of rain is over 25K gal per acre). Thi influent water will be controlled by an ice kral for GW and using berms snd channels. The surface water is being treated for the hvier Non conservative radionuclides as I said before. Their adsorption coefficients allow them to be "Stuck to the surface of adsorbents like GAC and Powdered Al). The adsowbents are holding the radionuclides till they are periodically desorbed. The water i as clen as it can get for now, And, I believe that the plans for more effective control mens are being "blue printe"
As I understand then, the Tritiated wter is taken up a s bio mass and the biomass is composted thus allowing several half lives of remediation within soil that is underlain by a 10_7 cm/sec composite liner.
Water that is kept from touching the plant property itself is allowed to runnoff with only monitoring at this point.
All I know is what Ive gleaned from a remediation Conf two years ago that was specific to nuclear accidents. Yeh water is going to the Pacific but it int like its being ignored as far as rad concentrations and activities. I understand they were looking at allowing water to discharge at Darcy Velocities into the nearby subduction zone. They wre looking at doing something like that in Calif for Organic chemical contaminants
