· JVASP-14593· Pu

Plutonium (Pu) is a synthetic radioactive metal in the actinide series, produced primarily through nuclear reactor irradiation of uranium. Its use is restricted to nuclear weapons programs, nuclear fuel cycles, and specialized research applications under strict international safeguards and regulatory control. Engineers encounter plutonium primarily in nuclear security, materials science research, and legacy facility management contexts rather than conventional commercial engineering.

Regulatory Screening

Environmental

Export Control

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.
