The Pacific Ocean contains approximately 170 million cubic miles of water.

1 mile = 5,280 feet
1 foot = 12 inches
1 mile = 63,360 inches
1 square mile = 4,014,489,600 square inches
1 cubic mile = 254,358,061,056,000 cubic inches
1 gallon = 231 cubic inches
1 cubic mile = 1,101,117,147,429 gallons = 1,101 billion gallons
17 X 10^8 cu mi = 187,189,915,062,930,000,000 = 187,189,915,062 BILLION Gallons of water or about 187 x 10 to the 18th power gallons of water.

I think it can diffuse a few billion gallons of radioactive water.

I doubt it. Otherwise we would have been dumping our radioactive waste into the ocean for many years. There would be no need for Yucca Mountain.

Several nuclear weapons were detonated in the Pacific during the 1950s and 1960s. From shot Baker 11 months after the defeat of Japan to various live testings of nuclear-armed torpedoes and depth charges.
