I think you were not talking about a d...netudiant,<br /><br />I think you were not talking about a direct release of the about 400,000 cubic meters of SARRY "pre-purified" water.<br />We all know this water is still grossly contaminated with its inventory in a whopping magnitude of about 1.2 megacuries of Strontium-90.<br />And in comparison with this, the daily release of up to three curies of Caesium-137 (and probably Strontium, too) is just peanuts.<br /><br />If ALPS works as advertised, and releases the water with all things (except tritium, ofc) at ND levels, there would be indeed no sensible reason (except maybe tritium decay) to keep the ALPS purified water stored.<br /><br />But, honestly, there is another thing to keep in mind.<br /><br />If they would construct concrete walls and dams to block tsunami and groundwater in- and outflow now, another question would arise:<br />Would it then be still possible to construct facilities to unload the four SFPs in the already very cramped area?<br /><br />Maybe this is the reason why we see no efforts be taken building walls and dams, and at the same time see the pool unloading schedule accelerated by the Abe govt.?<br />Atomfritznoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-79710357890046375422013-03-30T21:08:18.418-07:002013-03-30T21:08:18.418-07:00netudiant, unfortunately, yes, it would be too muc...netudiant, unfortunately, yes, it would be too much to expect rational thinking, particularly in Japan. <br /><br />Soil freezing?

It would make more sense to focus every effort on stopping the existing outflow, which should be pretty easy to achieve by freezing the ground. <br />The US was able to treat some of the most dangerous waste tanks at the Hanford site that way, before leakage from the tanks could pollute the Colombia River. Something similar is needed here, but it will take a long time based on the current plans for concrete walls and dams. netudianthttps://www.blogger.com/profile/11726679291917155189noreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-10499427461724446642013-03-30T16:57:33.557-07:002013-03-30T16:57:33.557-07:00Reduction factor of more than ten billions for Str...Reduction factor of more than ten billions for Strontium, for example?<br /><br />This sounds way too good to be true, I fear.Atomfritznoreply@blogger.com
