Radioactive Waste Vault

Description
The Radioactive Waste Vault is a high-capacity, scalable multiblock solution for storing and processing nuclear waste. Built using the same multiblock structure as Mekanism's Dynamic Tank, it offers a powerful alternative to standard waste management.
Size
- Minimum Size: 3 × 3 × 3
- Maximum Size: 18 × 18 × 18
Components
- Radioactive Waste Vault
- Radioactive Waste Valve
Features
- Scalable Storage Capacity: The larger you build the structure, the more radioactive waste it can hold.
- Scalable Decay Rate: The waste decay rate scales directly with the vault's physical size. As you expand the structure, the decay speed increases, allowing larger vaults to process waste far more efficiently than standard barrels.
Note: The example below is for a 3x3x3 structure.
