Senate Concurrent Resolution No. 120 expresses the Idaho Legislature's support for the advancement of used nuclear fuel (UNF) reprocessing capabilities within the state, emphasizing Idaho's unique position due to its existing infrastructure and workforce at the Idaho National Laboratory (INL). The resolution highlights the importance of modern reprocessing technologies in managing UNF, reducing high-level waste, and producing reactor-ready fuel, which aligns with national energy security and economic growth goals. It reaffirms Idaho's commitment to the 1995 settlement agreement with the U.S. Department of Energy (DOE) regarding the management of nuclear waste while advocating for potential modifications to facilitate reprocessing activities.

The resolution encourages collaboration among state agencies, INL, the DOE, and private industry to expand reprocessing research and initiatives, ensuring transparency and environmental protection in the process. It asserts that reprocessing is compatible with the terms of the 1995 settlement agreement and calls for the renegotiation of any restrictive provisions that may hinder reprocessing efforts. Additionally, the Legislature requests federal support for reprocessing initiatives and mandates a report on progress by the Governor and Attorney General in the 2027 legislative session, aiming to enhance Idaho's role in nuclear fuel management and research.
