If it were diluted to the same level it would be trillions of gallons, but this would be a terrible idea. The site is significantly too small because a long term SNF containment hole is about 100x as big as the spent fuel and needs to be separated from the next one for thermal reasons. The site is also woefully unsuited to containing something that dangerous. SNF is also a very small fraction of the intermediate and long lived waste generated by a nuclear plant.
