New paper, just published in Physical Review X Energy, on the muography of the G3 nuclear reactor

by Baptiste Lefevre and co-authors
doi.org/10.1103/PRXEnergy.4.01

The visualization software I developed for #Cosmology contributed in the mapping of the inner, inaccessible structure of the reactor.

▶️ see the video and interactive visualization here: journals.aps.org/prxenergy/abs

A screenshot captured on the frontpage of the Physical Review X Energy webpage showing an article thumbnail image, title, summary and other details. Title reads "3D Reconstruction of a Nuclear Reactor by Muon Tomography: Structure Validation and Anomaly Detection". Summary reads "Muon tomography, a non-invasive technique that can be used to image large, inaccessible structures, is combined with machine learning to create a 3D reconstruction of a historical nuclear reactor that reveals material density variations, including potential anomalies in the graphite core." Dated 28 January, 2025. Thumbnail image shows a 3D reconstructions and slices of the density field of the reactor.
A screenshot of a figure of the article, featuring a black on white technical drawing mixed with a colorful 3D visualization. Captions reads "3D visualization of the postprocessing of SART’s real data reconstruction, showing an isosurface of the density field 𝑑 =1.5 together with a 𝑦 =0 slice and the corresponding technical drawing. This 3D visualization is complemented by a video in Supplemental Material".

@gregeganSF @johncarlosbaez Agree, muons are minimal-ionizing-particles (doing a little ionization and don't shower up via bremsstrahlung as electrons do) and as such super detector friendly. We created cosmic muon detectors in the physisc lab at uni by anti-correlating two scintillator with a lead plates inbetween and there are school versions of that experiment even. Here I assume a large area would be useful and extracting momentum and direction are the challenging bit. Dark matter and neutrino experiments have muons as a major background, which is why e.g. #icecube built a large surface array of scintillators for vetoing them. Will check out the sources now...
