Plutonium is a key component used in nuclear weapons, and the proposal is already raising concerns in the Livermore community. If approved, there would be an increase in the amount of highly radioactive plutonium at the lab, as well as increased transportation of plutonium-related materials on local freeways. Community members and advocacy groups are concerned about the possible health and environmental risks, including accidents, fires, contamination, transportation crashes, or other security incidents. #publichearing #nnl #livermore #site300 #contamination ♬ original sound – Tri-Valley CAREs

@tri_valleycares 5 Years of the Treaty on the Prohibition of Nuclear Weapons Five years ago today, the Treaty on the Prohibition of Nuclear Weapons entered into force, making nuclear weapons illegal under international law. With 95 signatories and 74 ratifications, the growing global consensus is clear: the threat of nuclear weapons is unacceptable. It’s time for nuclear-armed states, including the U.S., to join. #TPNW #nuclearban #LLNL #livermore #nomorewars ♬ original sound – Tri-Valley CAREs
