“Reducing the San Onofre Nuclear Generation Station’s thirst for salt water would cost about $2.5 billion and require an untenable amount of construction under one of the region’s busiest freeways, according to recent estimates released by the power plant’s majority owner.

The plant, which now relies on massive amounts of seawater to cool the steam that spins its electrical generators, is looking at an alternative cooling method in response to a draft policy released June 30 by the state water quality control board. The panel wants all coastal power plants to cut their water intake by 95 percent to reduce the number of fish and fish eggs killed by the cooling process.

The policy, which is up for public comment at a hearing in Sacramento set for Sept. 16, recommends that San Onofre install cooling towers to manage heat released inside the plant rather than use a continuous stream of ocean water to do so. …”
