Mothers for Peace wants earlier closure of Diablo Canyon

San Luis Obispo Mothers for Peace applauds PG&E for its decision to close Diablo Canyon. However, our organization asserts that it would be in the best interests of ratepayers and the citizens of California if the shutdown date were moved forward to 2019/2020, rather than the 2024/2025 dates proposed by PG&E.

Among the reasons for this position are the following:

Early replacement of Diablo Canyon’s energy services is feasible

▪ Solar, wind and geothermal energy capacity is increasing rapidly.

▪ Innovation in energy storage capacity is advancing.

▪ Community Choice Aggregation is a growing movement.

Aging plant equals increased risks

▪ Diablo Canyon’s procurement of mechanical components began more than 50 years ago.

▪ It’s unlikely that Diablo Canyon reactors are mechanically capable of operating reliably until 2025.

▪ PG&E has issued a list of “canceled projects,” indicating the corporation is reluctant to spend funds needed for maintenance.

Seismic risks

▪ The age and degradation of the plant, coupled with the likelihood of seismic activity, creates economic and environmental risks to ratepayers.

Once-through cooling system is responsible for 80 percent of man-caused damage to marine environment along California’s coast

▪ Once-through cooling kills fish, eggs, larvae and other wildlife.

▪ It discharges tremendous amount of heated water directly into adjacent waters, damaging aquatic species, including plankton and plants that aquatic species depend on for survival.
