Westinghouse Electric Company has signed a contract with Slovenia’s state-owned power company, GEN energija, to evaluate the deployment of a reactor at the proposed Krško-II nuclear power plant.

The technical feasibility study (TFS) will evaluate the potential deployment of an AP1000® reactor. Westinghouse has partnered with Hyundai Engineering & Construction Company to carry out the TFS.

The Krško-II project is planned on a site next to the current Krško nuclear power plant, which also uses Westinghouse technology.

Westinghouse Energy Systems president Dan Lipman stated: “Since delivering the first Krško unit, which has operated very successfully since it started operating in 1983, Westinghouse has built a decades-long partnership with GEN energija through operational and fueling support. We are pleased to extend the relationship to closely study the feasibility of the Krško-II project.

“This potential AP1000 project will not only provide clean, reliable baseload power to Slovenians, it will also deliver real economic benefits and high-quality jobs for years to come while fostering Slovenia’s energy independence.”

The AP1000 reactor is a Generation III+ design featuring fully passive safety systems, modular construction and a compact footprint per megawatt electric.

Westinghouse is currently setting operational performance and availability records, with six units already in operation.

In addition to the operational reactors, 12 further AP1000 units are under construction and five additional units are contracted.

By 2030, 18 AP1000 reactors are expected to be operational globally.

The AP1000 technology has been chosen for nuclear energy projects in Poland, Ukraine and Bulgaria, and is being considered for locations in Europe, the UK, India and North America.

Westinghouse, KEPCO and KHNP reached a global settlement in January 2025 to resolve their long-standing nuclear IP dispute, paving the way for collaboration on new reactor deployments worldwide.
