The storage and management of radioactive wastes.
Why: high-level radioactive waste remains hazardous for thousands to millions of years, risks long-term groundwater and ecosystem contamination if containment fails, and safe, permanent disposal is technically and politically difficult. (By contrast, operational nuclear plants emit very little greenhouse gas; proliferation is a serious security/safety issue but less a direct, widespread environmental threat; high cost is economic.)
