Fusion campus study models heat reuse, according to Zenodo (CERN European Organization for Nuclear Research)
According to Zenodo (CERN European Organization for Nuclear Research), a paper published on 7 September 2026 proposes MetroVolt, a modeled deuterium–helium-3 fusion power system supplying direct-current electricity to AI data centers, without identifying a deployment location. According to Zenodo (CERN European Organization for Nuclear Research), its potential significance for data-center environmental management lies in reduced electrical conversion losses, waste-heat recovery and lower neutron output, but the concept depends on confinement performance far beyond demonstrated tandem-mirror results.
According to Zenodo (CERN European Organization for Nuclear Research), the design addresses energy efficiency and radioactive-source management, including a modeled mobile tritium inventory of 3.6 g; the paper does not establish alignment with global environmental agreements.
Economic & investment implications
According to Zenodo (CERN European Organization for Nuclear Research), the proposed architecture reduces the electricity-conversion chain from four-to-six stages to two-to-three, offering an efficiency rationale for data-center infrastructure development. According to Zenodo (CERN European Organization for Nuclear Research), the publication contains no financial information, so it does not establish capital requirements, operating-cost savings or commercial viability.

Key findings
According to Zenodo (CERN European Organization for Nuclear Research), modeled source-to-chip efficiency increases from 75.9% for conventional AC delivery to 88.1% for direct-current delivery.
According to Zenodo (CERN European Organization for Nuclear Research), absorption cooling powered by recovered heat lowers modeled facility power usage effectiveness from 1.35 to 1.17.
According to Zenodo (CERN European Organization for Nuclear Research), the required ion-confining plug potential is 248.75 kV, a target more than two orders of magnitude beyond demonstrated tandem-mirror performance that requires a dedicated experiment.
Research method
According to Zenodo (CERN European Organization for Nuclear Research), the study uses the Kronos toolkit and OpenMC, GPU-accelerated computation, global sensitivity analysis, Monte Carlo uncertainty analysis and comparisons with published literature. According to Zenodo (CERN European Organization for Nuclear Research), results are fixed design-point calculations rather than demonstrated plant performance, and alternative synchrotron-radiation models change the calculated plant energy multiplication from 0.39 to 1.32 or 4.56.
