The Holtec SMR-300 (small modular reactor) offers a unique optional Air-Cooled Condenser system, enabling operation in arid environments like Utah, where water resources are scarce.
A Florida-based company’s small modular reactor has been chosen to power an advanced nuclear project in Utah. Holtec International SMR-300 stands out with its advanced design rooted in 80 years of proven pressurized water reactor technology.
The transformative initiative is set to advance Utah’s clean energy goals under Operation Gigawatt. The Green River Advanced Nuclear Project leverages the innovative Holtec SMR-300 Small Modular Reactor technology, supporting reliable, carbon-free power generation tailored for the region’s needs. The Holtec SMR-300 offers a unique optional Air-Cooled Condenser system, enabling operation in arid environments like Utah, where water resources are scarce.
This“With Holtec’s restart of Palisades Nuclear plant in Michigan ongoing, and the first Holtec SMR-300s, Pioneer 1 & 2, in the NRC licensing process and early site preparation, the work by our partners to acquire sites for next-of-kind deployment in Utah is paramount to our Mountain West expansion strategy as part of Operation Gigawatt,”“Supply chain development follows reactor deployments, making the advancement of this project crucial to downstream supply chain investments in the state across the nuclear ecosystem. ” The company also revealed that the latest project supports Utah’s Operation Gigawatt goals and builds on the state’s growing nuclear ecosystem, including previous projects such as the Brigham City advanced nuclear initiative.
“Fulcrum Point is stepping into this project as a true development partner to help move the Blue Castle Project from years of groundwork into the next phase of execution,” said Chris Hayter, Founder of Fulcrum Point and Chief Operations Officer of Hi Tech Solutions. “Blue Castle has done important work to position this site for success, and we now bring the technical, operational, and project development capabilities needed to helpit through licensing, deployment planning, and eventual construction.
This project has the potential to strengthen Utah’s energy future, support rural economic growth, and deliver reliable power for decades to come. ” The Green River site, benefiting from extensive environmental and technical analysis including meteorological, seismic, and groundwater studies, also offers important logistical advantages such as existing water rights, access to the Union Pacific railway, proximity to I-70, and multi-market transmission opportunities.
The project supports Emery County’s long-standing identity as an energy-producing region and is expected to create construction and skilled energy sector jobs that will benefit workers, families, and local businesses as energy demand grows, according to a press release. This project supports Utah’s Operation Gigawatt goals and builds on the state’s growing nuclear ecosystem, including previous projects such as the Brigham City advanced nuclear initiative.
The company also revealed that the SMR-300 is a compact nuclear reactor that generates over 300 MWe using a simple, two-loop system with a built-in steam generator and pressurizer. It’s designed to be safer and more reliable by using passive safety features that work without needing operators to step in during emergent events.
Because of this, it needs a lot fewer staff—around 270 people for a twin reactor plant — for an economic cost of operation compared to older nuclear plants. The SMR-300 is a two-loop PWR, utilizing two cold legs each with a vertically mounted reactor coolant pump, two hot legs, and a single OTSG with an integral PZR stacked on top. The OTSG is located adjacent to the reactor pressure vessel and is designed to produce superheated steam at full power-conditions.
The single, vertical, straight tube, once-through, countercurrent flow OTSG operates in the general ranges of pressure and temperature of existing PWR OTSG designs,Prabhat, an alumnus of the Indian Institute of Mass Communication, is a tech and defense journalist.
