So, a gallon of water weighs about 8 lbs so if they’re dumping 1.25 million tons, that equates roughly to to 312 million gallons. I think describing it in tons is misleading and the gallon number lets people really know how much water they’re planning on dumping. They’ve got plenty of unused real estate, build more tanks (out of stainless) and let the radiation cool down.
Run the water through an ion exchange process. There are zeolites specific to elements like cesium. Send the spent resin to be mixed with borosilicate glass and melted, then placed in steel casks. Same process used at the West Valley Demonstration Project.

This is the same technology used by the French nuclear industry for decades.
I worked on this project.
The water being dumped is not even a drop in the bucket it is so tiny relative to the ocean. Reporting it in tons, not 312 million gallons or 957 acre feet, is misleading. The solution to pollution is dilution.
Volume of Pacific Ocean - roughly 170 million cubic miles.
300 million gallons works out to not quite two gallons PER CUBIC MILE!
Half life of tritium (the main contamination isotope) is only 12.3 years.
It will all go away naturally. Almost half has already decayed.
