· JVASP-20072· UOs2

UO₂ (uranium dioxide) is a ceramic compound and the primary chemical form of uranium fuel used in nuclear reactors. It is a dense, refractory material that remains stable under extreme temperatures and intense radiation, making it the de facto standard for commercial nuclear power generation. Engineers select UO₂ for its ability to withstand the demanding thermal and neutron-irradiation environment of reactor cores while maintaining structural integrity over extended operational periods.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
