Utah Associated Municipal Power Systems (UAMPS) and NuScale Power Corp. (NuScale) have mutually agreed to terminate the Carbon Free Power Project (CFPP), a small modular reactor (SMR) project that was planned for construction on Idaho National Laboratory (INL) property near Idaho Falls, Idaho.

“Despite significant efforts by both parties to advance the CFPP, it appears unlikely that the project will have enough subscription to continue toward deployment. Therefore, UAMPS and NuScale have mutually determined that ending the project is the most prudent decision for both parties,” the developers said in an announcement issued on Nov. 8.

UAMPS is a political subdivision of the State of Utah that provides comprehensive wholesale electric-energy, transmission, and other energy services, on a nonprofit basis, to community-owned power systems throughout the Intermountain West, including in Utah, California, Idaho, Nevada, New Mexico, Oregon, and Wyoming. The CFPP was a major project for UAMPS. At one point in time, it was envisioned to be a 720-MWe power plant comprised of 12 NuScale SMR power modules. As time progressed and member subscriptions for plant production lagged expectations, the project was scaled back to six modules with a combined capacity of 462 MWe
