Westinghouse places initial orders for Polish plant

COMMENT – Funding largely subsidised by the government

14 October 2026, WNN

Westinghouse has placed conditional purchase orders for safety-related modules with four Polish companies, a week after being commissioned to begin ordering long-lead items for the first unit of Poland’s planned first nuclear power plant.

Three Westinghouse AP1000 reactors are planned for the plant at the Lubiatowo-Kopalino site in the Choczewo municipality in Pomerania in northern Poland. The AP1000 reactor design uses modular construction techniques, enabling large structural modules to be built at factories and then installed at the site. The reactor building and systems consist of dozens of prefabricated, steel-concrete structural and mechanical modules.

Polskie Elektrownie Jądrowe (PEJ) last week gave Westinghouse the go-ahead to start ordering long-lead items for the project’s first AP1000 unit. It said the scope of the order for the first unit covers six key components of the nuclear island, including the reactor containment vessel and associated structural modules.

The conditional purchase orders cover the CA02 Walls Module Scope for Mostostal Kielce, the CA03 Module Scope for EPG, the CA05 Walls Module Scope for Mostostal Krakow, and the CA20 Floors Module Scope for FAMAK.

In an AP1000 unit, the CA02 walls module and the CA03 module are part of the in-containment refuelling water storage tank in the containment building. The CA05 walls module consists of reinforced steel plates that provide protective walls separating various rooms in the containment building. The CA20 floors module consists of reinforced concrete slabs placed on steel plates to form the floors of the larger CA20 module that houses plant equipment inside the unit.

Westinghouse said that, as part of its ongoing supplier development programme, each of the four companies is steadily progressing toward full NQA-1 compliance. Upon NQA-1 certification and the successful fabrication of pre-production qualification mock-ups – which demonstrate increasing readiness to support future nuclear safety-related manufacturing activities – Westinghouse will award companies the full project scope……………………………………………..

Early procurement of components with long lead times is common in nuclear projects worldwide. It helps secure the availability of production capacity, mitigates the risk of delays, and supports timely project implementation. The scope of work includes preparing technical documentation, quality and supervision plans, selecting and contracting suppliers, and initiating material procurement necessary to commence production. The production and delivery of finished components to the construction site will be handled as part of a subsequent order, which PEJ plans to issue as part of the power plant construction contract.

Last month, Polish construction engineering firm Polimex Mostostal was selected by Bechtel to deliver, assemble and commission two large-scale assembly halls as part of the project to construct the Lubiatowo-Kopalino plant. Under the contract, Polimex Mostostal will provide a key element of the production and assembly facilities for the construction of three Westinghouse AP1000 units commissioned by PEJ. The contract includes a full range of engineering services, including the development of design documentation for obtaining necessary permits, as well as the supply of materials, structural assembly, testing, acceptance, and final handover of both halls.

Construction of the Lubiatowo-Kopalino plant is scheduled to begin in 2028. Under the recent update to the country’s nuclear power programme, the first unit is scheduled to start commercial operation in 2036, and the plant is expected to reach full capacity by 2038 – three years later than previously planned. https://www.world-nuclear-news.org/articles/westinghouse-places-initial-orders-for-polish-plant
