NuScale Power Achieves Standard Design Approval from NRC for 77 MW SMR

LCG, May 30, 2025--NuScale Power Corporation (NuScale), a leading provider of advanced small modular reactor (SMR) nuclear technology, yesterday announced that it has received design approval from the U.S. Nuclear Regulatory Commission (NRC) for its uprated 77 MW power modules. NuScale states that it remains the only SMR technology company with design approval from the NRC, and the company remains on track for deployment by 2030, with 50- and 77-MW SMR options.

EIA Presents Analysis of California's Solar and Wind Power Curtailment Challenges

LCG, May 29, 2025--The U.S. Energy Information Administration (EIA) released an analysis yesterday showing that the California Independent System Operator (CAISO), the grid operator for most of the state, is increasing its curtailment of the rapidly growing solar- and wind-powered generation facilities in order to balance electricity supply and demand, which is necessary to maintain a stable electric system.

Reactor Company Applies for MOX Fuel Permit

LCG, February 27, 2003-Duke Energy has applied to install mixed oxide (MOX) fuel lead assemblies.

Mixed oxide fuel combines the uranium oxide normally used in reactors with roughly 5 percent plutonium oxide. European companies have used MOX fuel for over twenty years, in part to reduce weapons-grade plutonium stockpiles.

35 European reactors utilize MOX fuel, but in the United States some people are cautious about its use for safety reasons. Fission of MOX fuel, because of its plutonium content, may cause increased embrittlement of the reactor metal, and MOX fuel, until expended in the reactor, could still be used by terrorists.

Duke Energy has announced that it wants to use MOX fuel assemblies in either the McGuire or Catawba reactor starting in 2005. Four of the 193 fuel assemblies would be MOX.

Duke Energy began the regulatory process today as it sent in its preliminary application to the Nuclear Regulatory Commission.
