BWX Technologies partners with Rolls-Royce on SMR development

BWX Technologies (NYSE: BWXT) jumped 5.8% in pre-market trading after announcing a nuclear steam generator design contract and a memorandum of understanding (MoU) with Rolls-Royce (OTCPK: RYCEF, RYCEY).
The agreements aim to support future collaboration on developing Rolls-Royce’s Small Modular Reactor (SMR) program.

Key details of the partnership

Rolls-Royce SMR has agreed to procure steam generators for multiple reactor units from BWXT.
Both companies will work together on a localization plan for future manufacturing and deployment of SMRs in global markets.
The partnership underscores a shared vision to accelerate clean nuclear energy adoption through modular, scalable power systems.

Strategic significance

Rolls-Royce SMR is currently the only company with multiple commitments to develop small modular reactors in Europe, having:

Been selected as the preferred bidder in the Great British Energy–Nuclear SMR competition.
Signed with European utility CEZ to build up to 3 GW of new nuclear capacity in the Czech Republic.

This collaboration positions BWXT as a core supplier of critical nuclear components for the Rolls-Royce SMR fleet, potentially expanding its presence in the European and global nuclear markets.

Leadership commentary

Ruth Todd, Operations and Supply Chain Director at Rolls-Royce SMR, said:

“The agreement with BWXT for the design of the nuclear steam generators — reinforced by an MoU to support the first units in a global fleet of Rolls-Royce SMRs — is another major stride forward for our organization.”

Market and policy backdrop

BWXT shares also gained momentum amid broader optimism following the U.S. government’s partnership with Cameco, Brookfield Asset Management, and Westinghouse, aimed at building at least $80 billion worth of new nuclear reactors.
The deal highlights a growing renewed focus on nuclear power as part of the global clean energy transition and AI-driven energy demand surge.
