Nuclear Proliferation Concerns Regarding Small Modular Reactors and Weapons Testing. Henry Sokolski raises proliferation concerns about Small Modular Reactors (SMRs) using High-Assay Low-Enriched Uranium (HALEU) fuel (20% enriched). Declassified cables from 1954 and 1977 suggested that uranium above 10% requires special concern, demanding a review before SMRs are exported. Sokolski also clarifies that US maintenance of its nuclear arsenal relies on non-critical tests and simulations, not full-yield explosions, though adversaries may be conducting critical tests.
