Amentum Selected for Nuclear-Powered AI Data Center Project in US

Key Facts

In a move reflecting the growing trend of integrating sustainable energy solutions with advanced infrastructure, Amentum has been selected by the U.S. National Nuclear Security Administration (NNSA) to negotiate a lease at the Savannah River Site in South Carolina. The project aims to pair a 1-gigawatt (GW) AI data center with approximately 2 GW of dedicated on-site nuclear power generation. This selection is part of a broader U.S. Department of Energy initiative to utilize federal land to meet the surging power demands of modern data centers.

This project represents a new public-private partnership model designed to address energy consumption challenges in the tech sector, as regulators seek to provide reliable and continuous power sources. According to reports, integrating nuclear capabilities directly into data center sites reduces pressure on public grids and provides long-term operational stability. These developments come at a time of increased global market interest in clean energy stocks and AI infrastructure, amid expectations of growing investment in this vital sector.

Operationally, the agreement remains in the negotiation phase and is subject to final investment and regulatory approvals. In the absence of updated price data for the instrument at the time of this report, investors are closely monitoring the progress of negotiations as a future catalyst. Markets are also looking ahead to significant economic data in the coming days, including the UK Consumer Price Index (CPI) scheduled for July 22, 2026, which may influence investor sentiment in global energy and infrastructure sectors.
