From the Pages of Nuclear News: Industry update July 2025
Here is a recap of industry happenings from the recent past:
Utah moves to forefront of advanced nuclear development
EnergySolutions has signed a memorandum of understanding to partner with Utah’s Intermountain Power Agency and the Utah state government to explore the development of advanced nuclear power generation at the Intermountain Power Project (IPP) site near Delta. The MOU calls for the leveraging of existing infrastructure at the IPP site; potential development of small modular reactor nuclear baseload power; potential synergy with the existing Intermountain Power Agency energy hub and advanced grid stabilization technologies; collaboration with local, state, and regional stakeholders; and commitment to rural economic development and job creation in the state. The partnership is aligned with Utah Gov. Spencer Cox’s Operation Gigawatt, an initiative to double Utah’s energy production over the next 10 years.
