X-energy Commences First Irradiation Tests of Advanced TRISO-X Nuclear Fuel at Idaho National Laboratory

LCG, November 6, 2025--X-energy Reactor Company, LLC, (X-energy) and the U.S. Office of Nuclear Energy today announced the start of confirmatory irradiation testing at Idaho National Laboratory (INL) to qualify X-energy’s proprietary TRISO-X fuel pebbles for commercial use in the Xe-100 Small Modular Reactor (SMR). (TRISO stands for TRi-structural ISOtropic). This is the first time that TRISO-X fuel pebbles will undergo irradiation testing in a U.S. lab, which is a critical step in meeting requirements set forth by the U.S. Nuclear Regulatory Commission (NRC) for the commercial deployment of advanced reactors that will use the fuel.

NextEra Energy and Google Collaborate on Accelerating Nuclear Power Deployment

LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

Senators Propose National Renewable Electricity Standard

LCG, September 22, 2010--Senators Bingaman (New Mexico) and Brownback (Kansas) yesterday announced plans to reintroduce a bill to create a federal renewable electricity standard (RES). The legislation is alleged to increase our energy security, enhance the reliability of the electricity grid by creating more homegrown renewable energy, and reduce our greenhouse gas emissions.

The stand-alone, 43-page RES bill is almost identical to the RES included in the American Clean Energy Leadership Act, S. 1462, according to Senator Bingaman. The bill requires electricity suppliers to ratchet up the percent of renewable energy supplies (or energy efficiency improvements) from 3 percent in 2012 to 15 percent in 2021. The bill is designed not to affect state programs.

Like prior the proposal, the bill includes (i) an exemption for utilities selling less than 4 million megawatt hours per year of electricity and (ii) the option to pay alternative compliance payments to the Secretary at a rate of 2.1 cents per kWh.

Renewable energy sources include wind, solar, ocean, geothermal, landfill gas, incremental hydropower, hydrokinetic, and new hydropower at existing dams, an expanded waste-to-energy definition that includes municipal wastes, and biomass.

Although biomass is included as a renewable resource, the bill does nothing to address the carbon neutrality of biomass, which the Environmental Protection Agency (EPA) has called into question with its proposed Tailoring Rule that does not treat biomass as carbon neutral. Without carbon neutrality, biomass development will likely be limited, and it will not become the primary, non-hydro source of renewables, as forecast this year in the Energy Information Administration's Annual Energy Outlook.

Senator Bingaman states, "I think that the votes are present in the Senate to pass a renewable electricity standard. I think that they are present in the House. I think that we need to get on with figuring out what we can pass and move forward."
