Inside California’s last nuclear power plant — as locals fear it’ll have catastrophic meltdown

California’s Last Nuclear Power Plant: A Closer Look

Have you ever wondered what California’s last nuclear power plant looks like? PG&E recently gave KQED a rare glimpse inside the Diablo Canyon Power Plant in San Luis Obispo. Originally facing a 2022 closing date, the plant is now set to operate until at least 2030.

Located near the warm waters of Diablo Cove, the plant draws billions of gallons of water per day for cooling purposes. However, this process results in the discharge of water that is 16 to 17 degrees hotter back into the environment. Despite being situated in a de facto marine sanctuary, the plant’s cooling system has been reported to cause the deaths of nearly two billion larval fish annually, leading to concerns about the impact on the surrounding ecosystems.

During the tour, KQED explored the turbine deck, where massive turbines generate electricity. This area is hot, loud, and close to where uranium atoms are split to produce energy. The plant generates approximately 8.5% of California’s power by using the heat from split atoms to warm water, which then releases steam to power the turbines.

One of the most intriguing aspects of the tour was the simulator used for training employees to handle catastrophic nuclear meltdowns. This simulator replicates the plant’s control room and has been a requirement for all nuclear power plants since 1979. Despite safety measures in place, there are still concerns about potential disasters.

Protesters, such as Linda Seeley, Vice President of Mothers for Peace, have been voicing their concerns about the plant’s nuclear waste storage. The group is worried about the long-term effects of the waste on future generations. While PG&E assures that the waste is stored safely, activists remain vigilant about the potential risks.

Diablo Canyon is currently the state’s only operational nuclear power plant, and plans are in place for it to operate until 2030, with a potential extension until 2045 pending state legislature approval. Governor Gavin Newsom has praised the plant for its contribution to clean energy generation in California, emphasizing the importance of a reliable grid and addressing extreme weather challenges.

While the prospect of the plant’s closure may appease anti-nuclear activists, it also raises concerns about the impact on California’s energy sources and costs. As the state navigates its energy future, Diablo Canyon remains a significant player in the quest for a safe, affordable, and resilient energy landscape.
