Categorical Exclusion Determinations: B3.6

This Second Amended Determination follows the approval of additional funding, extended period of performance, and new project milestones to support the project team's small-scale research and development of a simple, scalable route for immobilizing multiple waste streams (metals, salts, carbon) from any potential advanced reactor fuel cycle into a singular, high-density, durable cermet (a heat-resistant ceramic and metallic composite) waste form.
