Which risk escalates when containment fails around decaying reactor fuel?

💡 Explanation

Environmental contamination risk increases, because the mechanism is diffusion of radioactive isotopes into the surrounding environment during alpha decay. This is more concerning given fuel volatility, therefore radionuclides spread, rather than fuel remaining contained or structural helium increase after decay.
