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.

UniStar Submits Application to Build Nuclear Reactor

LCG, November 16, 2007--UniStar Nuclear Energy, a joint venture between Constellation Energy and The EDF Group, yesterday submitted an application to the Maryland Public Service Commission (PSC) for a Certificate of Public Convenience and Necessity (CPCN) to construct a 1,600-MW nuclear reactor at Constellation Energy's existing Calvert Cliffs Nuclear Power Plant in Lusby, Maryland. Unistar anticipates a PSC decision by the end of next year.

Unistar filed in July with the Nuclear Regulatory Commission (NRC) the environmental report portion of a combined construction and operating license (COL) application to build the reactor. Unistar plans to submit the remainder of the application by March 2008.

Unistar Nuclear's application will include AREVA's 1,600-MW, U.S. Evolutionary Power Reactor (US EPR). The US EPR is based upon AREVA's 1,600-MW, European EPR that is now being deployed in Europe. One EPR reactor is currently under construction in Finland. AREVA completed phase one of its U.S. EPR Design Certification pre-application process with the NRC. AREVA expects that the Design Certification application will be validated by 2010, which would enable a U.S. EPR to be licensed and ready for operation as early as 2015.

Unistar has not made a final decision to build this new advanced-design reactor at Calvert Cliffs. According to Constellation, the ultimate decision to build will not be made until the overall economics and risks associated with the project are better defined, including the availability and cost of federal loan guarantees, and state and local fiscal policies that affect the tax treatment of the proposed plant.

Unistar is also considering the installation of another nuclear reactor at Constellation Energy's Nine Mile Point nuclear facility in upstate New York.
