Last Energy Launches 5 MW Nuclear Reactor Project in Texas

Last Energy has taken a significant step in advancing nuclear technology by announcing the deployment of a pilot microreactor at Texas A&M University’s RELLIS campus in Texas. This project features the PWR-5, a five megawatt reactor designed to demonstrate safe, low-power criticality, with plans to eventually generate electricity for the grid. The initiative is fully financed by private capital and is expected to commence testing in summer 2024.

Last Energy has been selected by the U.S. Department of Energy (DOE) for fast-tracked licensing under its New Reactor Pilot Program, an effort initiated by an executive order from former President Donald Trump. This marks the company’s inaugural reactor deployment in the United States, positioning it as a leader in the shift towards modern nuclear solutions.

In a statement, Robert Albritton, chairman of the Board of Regents of the Texas A&M University System, expressed optimism about the project, saying, “This pilot project is an example of what’s possible when we try to meet the needs of the state and tap into the latest technologies.” He emphasized that this development represents a proud moment for the Texas A&M System and an important step forward in unleashing American energy innovation.

The CEO and Founder of Last Energy, Bret Kugelmass, highlighted the project’s potential, stating, “We’re partnering with Texas A&M to usher in the next Atomic Era.” He noted that with secured fuel, an optimal site at RELLIS, and DOE authorization underway, the conditions are ideal for showcasing a standardized, scalable microreactor product to the United States.

Technical Specifications of the PWR-5 Reactor

The PWR-5 reactor is a scaled-down version of Last Energy’s larger PWR-20 design, which has a capacity of 20 megawatts (electric) and 80 megawatts (thermal). This larger reactor aims to provide behind-the-meter solutions for industrial facilities and boasts a 95 percent uptime rate. With a 72-month fuel cycle, it can be conveniently refueled using modular nuclear batteries.

The PWR-5 features a closed-cycle air cooling system for its tertiary loop and is designed for flexibility in power output to adapt to increasing energy demands. Last Energy has implemented industry-standard equipment and has partnered with over 100 global supply chain partners to ensure component availability, operational experience, and cost-effectiveness.

Additionally, the PWR-20 reactor has a compact footprint of just 0.3 acres, allowing it to be situated closer to energy consumption sites, which minimizes transmission losses. This compact design means it can be assembled on-site within a mere four months using road-transportable modules, further enhancing its appeal as a modern energy solution.

The reactor will utilize standard UO pellets with less than 4.95 percent enrichment, positioning it as a safe and efficient option for future energy needs. As the project moves forward, it stands as a testament to the potential of innovative nuclear technology in addressing the energy challenges faced by the United States and beyond.
