Microreactors are a class of very small modular reactors targeted for non-conventional nuclear markets. The U.S. Department of Energy (DOE) supports a variety of advanced reactor designs, including gas, liquid-metal, […]

The fate of Pacific Gas & Electric’s (PG&E’s) Diablo Canyon Power Plant is expected to be decided by year-end, with the California Public Utilities Commission (CPUC) set to hear final arguments about the plant’s future on November 28.
The 2.2-GW nuclear plant has operated near Avila Beach, California, since 1985. A judge in early November supported PG&E’s plan to retire the plant’s two Westinghouse-designed 4-loop pressurized-water reactors when their federal operating licenses expire in 2024 and 2025.
PG&E has said several factors entered into its decision to shutter the plant, which is the last operating nuclear facility in California. On its website, the utility says, “California’s energy landscape is changing dramatically. State policies that focus on renewables and energy efficiency, coupled with projected lower customer electricity demand in the future, will result in a significant reduction in the need for electricity produced by Diablo Canyon Power Plant past 2025.”
Proponents of keeping the plant in operation argue it was built to last a century.…
Panelists debating the pros and cons of a regionalized western power grid seemed to agree that the development of such a system is inevitable, but they disagreed on how fast the evolution should occur.
The panel discussion took place during the California Independent System Operator (ISO) Stakeholder Symposium held on September 7 in Sacramento. At one point, the moderator of the session, John Danner, senior fellow at the University of California, Berkley, Hass School of Business, suggested that the dialogue had progressed beyond the question of whether or why a regional approach might be beneficial, to a debate about how and when it should be implemented (Figure 1).

“It’s certainly true that the physics suggest operating a bigger grid is better,” said Marc Joseph, attorney with Adams, Broadwell, Joseph, and Cardozo, “but .…
