Now that the nuclear horses are getting out…again. (Thanks to wdydfae for the link.)
I have no idea why they didn’t have pumps set up from the beginning. I know it’s a real pain, given the water volume they must deal with. And filtering tritium from water isn’t nearly as easy as separating things like cesium and strontium.
But it would have been less painful if they hadn’t waited until the last minute.
