San Onofre Nuclear Generating Station: Progress, Problems, and the Politics of Nuclear Waste


Decommissioning of the facility is well underway and estimated to be approximately 60–80% complete. Many of the original structures have already been dismantled. The once-iconic “twin domes,” which for decades defined the skyline along Interstate 5, are scheduled for demolition beginning in late 2026 or 2027. For some, their removal will symbolize the end of an era. For others, it represents only partial closure.

What remains, however, is the most consequential issue of all: nuclear waste.

Approximately 3.6 million pounds of spent nuclear fuel are still stored on-site. By 2020, all the radioactive fuel was transferred from cooling pools into stainless steel canisters encased in thick concrete, a process known as “dry storage.” These canisters now sit roughly 100 feet from the Pacific Ocean. While this arrangement is officially classified as “temporary,” there is no federal timeline for when the waste will be relocated to a permanent national repository.

This is where the problem shifts from engineering to governance.

For decades, the federal government has carried the legal obligation to develop and maintain a permanent storage solution for the nation’s nuclear waste. Yet no such facility is operational. Communities like ours are left hosting what was never intended to be permanent storage sites. The burden falls on local ratepayers and residents who must live with the uncertainty, while Washington continues to delay long-term resolution.

The federal government’s inaction has created a patchwork of stranded nuclear waste sites across the country. The absence of a centralized repository is not merely a bureaucratic oversight; it represents a failure of political will. Ratepayers have funded the Nuclear Waste Fund for years, yet the promised solution remains elusive. Meanwhile, coastal communities like San Onofre carry both the physical and psychological weight of that delay.

In the midst of this stagnation, Mike Levin, who represents California’s 49th Congressional District, has emerged as a consistent advocate for progress. Representative Levin has pressed federal agencies for transparency, demanded stronger safety standards, and worked to accelerate efforts toward consolidated interim storage and ultimately a permanent repository. His engagement has included direct oversight efforts, community outreach, and legislative advocacy aimed at ensuring that San Onofre does not become a forgotten liability.

While demolition crews continue their work and the domes await their final chapter, the larger story remains unfinished. The dismantling of buildings is measurable. The removal of nuclear waste is not. Until the federal government fulfills its longstanding obligation to establish a permanent solution, San Onofre will remain a symbol not just of decommissioning—but of unfinished federal responsibility.

The future of the coastline should not hinge on indefinite “temporary” storage. The technology exists. The funding has been collected. What remains is decisive action.
