Editorial interest 87/100 Selection signal · not a rating of the site

An offline nuclear-engineering reference app with eleven calculators for nuclides, decay, dose, shielding, reactor physics, activation, and related work.

Landing page captured for the 2026-08-27 issue.

Field notes

The app ships its nuclear datasets locally and reports zero network calls, making the offline claim concrete rather than merely promotional. Its reference layer includes 3,383 ground states from IAEA NUBASE2020 / AME2020, gamma data for 120 emitters, and NIST attenuation coefficients for nine materials. Several tools expose domain-specific workflows, including Bateman decay-chain solutions with CSV export, Xe-135 transients, and shielding calculations using emission spectra and buildup.
