Reprising:

There are 187000000000000 million gallons of water in the Pacific Ocean, meaning that "radioactive waste" is 2.1 x 10^-10% of the body of water itself. The waste takes the form of HTO, tritiated water, which has extremely low bioavailability and has already been introduced in abundance to the ocean by other events. There are things to be alarmed about, but this isn't one of them.
