Profiling Reactor Technology: Westinghouse and Oklo

February 24, 2026 - 02:04

The landscape of nuclear energy is undergoing a significant transformation, driven by innovators in both the public and private sectors. At the forefront of this shift are two companies charting very different, yet equally ambitious, paths: the industry giant Westinghouse and the agile startup Oklo.

Westinghouse, with its deep historical roots in conventional nuclear power, is leveraging its extensive experience to evolve proven technology. The company is focusing on advanced large-scale reactor designs that aim to enhance safety, efficiency, and operational performance. Their approach represents a strategic evolution of existing light-water reactor technology, seeking to provide reliable, high-capacity baseload power for large grids and industrial applications.

In stark contrast, Oklo is pioneering a radically different model. The company is developing compact, fast reactor systems designed to operate autonomously for years without refueling. These micro-reactors are intended for decentralized power generation, potentially supplying clean energy to remote communities, industrial sites, and military installations. Oklo's vision embodies a new paradigm of scalable, portable nuclear energy.

Together, these two entities highlight the diverse strategies being pursued to make nuclear power more adaptable, efficient, and integral to a future low-carbon energy mix. Their progress is closely watched as a bellwether for the broader advanced reactor industry.
