You are looking at CCW Condenser Cooling Water. Very, very high volume, low pressure.330,000gpm typical on 500MW units. Depending on lake water design temps. Heat transport when under power does require 10's of thousands of gallons per minute. Main headers are 2 to 4ft in dia max depending on design. However heat production when shut down, IF they can keep the unit sub critical is much lower. Probably less than 50MW after 24hrs. Residual decay heat from short lived isotopes is much less than running power/heat. 1500gpm of muddy salty fish whiz looks better than fuel exposed due to low coolant level. Apparently the old #1 BWR was damaged in the last quake and repaired. Then slated for shutdown due to old age last year. Too bad the old clunker was given a life extension. It just wasn't built with today's simpler passive safety systems. Engineers in the 1950's, 1960's, and 1970's thought more complex was better.For reasons unknown they preferred to pump emergency cooling water. Instead of letting gravity supply emergency cooling. Containment was a joke too. A square shaped concrete block building can't handle an over pressure. Compare that to 2 to 4 ft thick steel reinforced heavy concrete round building. Connected to a vacuum building with a quenching system.
