Join us for the premier international event on nuclear waste management, the Scientific Basis for Nuclear Waste Management Symposium (SBNWM), taking place from November 2–7, 2025, at the Three Rivers Convention Center in Tri-Cities, Washington, USA.

Hosted by Pacific Northwest National Laboratory (PNNL) and endorsed by the Materials Research Society, the SBNWM Symposium gathers experts and young scientists from research and waste management organizations to discuss the latest innovations and challenges related to the safe management and disposal of nuclear waste. From materials science breakthroughs to collaborative efforts aimed at improving nuclear waste treatment, this event serves as a platform for knowledge exchange and solution development. 

More details to be announced.
