Nuclear Waste Repository 2D — Decay Heat & Radionuclide Migration

A decaying radionuclide inventory heats a waste canister and diffuses through an engineered clay buffer into the surrounding host rock, where groundwater can carry it onward — watch containment fail as you degrade the buffer or raise the flow rate.

This 2D companion swaps the 3D repository's decorative particle scene for a real transport model: a canister at the centre emits a radionuclide inventory whose activity — and heat output — decays exponentially with the chosen half-life, and a grid-based advection-diffusion field carries that activity outward through an engineered clay buffer and into the surrounding host rock. Degrade the buffer or turn up the groundwater flow and the plume reaches the far field faster, driving the migration-risk readout up in real time.

⚙ Under the hood

Grid-based 2D advection-diffusion-decay solver (explicit finite differences): decay heat and source strength follow P(t)=P₀e^(-λt) with λ=ln2/half-life, while the concentration field obeys ∂C/∂t = D∇²C - v·∇C - λC across three zones (canister core, clay buffer, host rock) with independently controllable buffer diffusivity and groundwater advection.
