London, Tuesday 20 January 2026
Amentum has secured the pivotal delivery role for Rolls-Royce’s Small Modular Reactors, a strategic move set to generate 1.5GW of low-carbon energy and over 8,000 British jobs. Commencing with deployments in the UK and Czech Republic, this partnership signals a major shift towards the commercial viability of scalable nuclear infrastructure and strengthened energy security across Europe.

Operational Framework and Strategic Responsibilities

Under the collaborative agreement announced on 20 January 2026, Amentum (NYSE: AMTM) assumes the critical role of programme delivery partner, tasked with the integration, governance, and construction management of the Small Modular Reactor (SMR) fleet [2][3]. This partnership leverages Amentum’s extensive workforce of approximately 50,000 employees and its historical involvement with Rolls-Royce, dating back to a consortium formed in 2016 to develop modular power stations [2][3]. Work is set to commence immediately, focusing on the first deployments in the UK and the Czech Republic, where Amentum will apply its full nuclear life cycle experience to ensure the projects remain on schedule and within budget [1].

Engineering a Low-Carbon Future

The technical specifications of the Rolls-Royce SMR design promise high efficiency within a compact footprint. A single SMR power station is designed to occupy a site roughly the size of two football pitches while generating enough electricity to power approximately one million homes [4]. In the UK alone, Rolls-Royce SMR aims to deliver up to 1.5GW of low-carbon energy to the national grid [1][2]. This deployment is not merely an infrastructure project but a significant economic catalyst; the initiative is projected to create more than 8,000 long-term jobs in Britain [1][4]. Loren Jones, Amentum’s senior vice president, confirmed that the company plans to support this job creation trajectory over the next four years [3].

Global Partnerships and Market Context

To bolster the delivery of this complex infrastructure, Amentum has secured the support of HOCHTIEF, a global infrastructure group, following a Memorandum of Understanding announced on 19 January 2026 [5]. HOCHTIEF brings decades of nuclear experience, having been involved in the sector since the 1950s and contributing to an overall output of 37 GW globally [5]. This collaboration aligns with broader market trends; at COP28, over 25 countries pledged to triple nuclear capacity to 1,200 GW by 2050, driving a market where cumulative investments are forecast to exceed €600 billion by 2040 [5]. John Heller, CEO of Amentum, described the collaboration as a critical enabler for strengthening energy security across the UK and continental Europe [2].
