ISO discusses nuclear energy options and waste disposal challenges in California
During a recent meeting of the Senate Rules Committee in California, discussions centered on the future of nuclear energy and its role in the state's energy landscape. A key takeaway from the dialogue was the recognition of nuclear power as a carbon-free energy source, which is gaining attention nationwide as states seek sustainable energy solutions.

One committee member emphasized the importance of being resource agnostic, stating that the Independent System Operator (ISO) is obligated to utilize the most suitable and cost-effective power sources for consumers. However, decisions regarding which technologies align with California's energy needs ultimately fall to the Public Utilities Commission (PUC), which oversees resource adequacy and long-term planning.

The conversation also highlighted ongoing challenges related to nuclear energy, particularly waste disposal. A member noted that the federal government has made little progress in addressing waste management, which poses significant hurdles for the nuclear industry. For instance, spent fuel from the Rancho Seco nuclear facility remains in dry cask storage, awaiting federal action that has yet to materialize.

While acknowledging the complexities and costs associated with nuclear energy, the committee expressed hope for advancements in small modular reactors, which have been discussed for over a decade. The potential for these technologies to be both cost-effective and quickly deployable could play a crucial role in California's energy future.

As the state navigates its energy transition, the discussions from this meeting underscore the importance of exploring all available technologies while addressing the pressing issues of waste management and cost-effectiveness in the nuclear sector. The outcomes of these discussions will likely influence California's energy policies moving forward.
