· JVASP-78817· PuO2

Plutonium dioxide (PuO2) is a refractory ceramic compound and the primary chemical form of plutonium used in nuclear applications. It is encountered in nuclear fuel fabrication, where it serves as the fissile material in reactor fuel pellets, and in specialized contexts involving plutonium storage, handling, and disposition. PuO2 is notable for its extreme radiotoxicity and thermal properties, making it essential for nuclear power generation and legacy nuclear materials management, though its use is restricted to authorized nuclear facilities and governed by international safeguards.

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.
