Lead Cask
The only safe stationary home for hot radioactive cargo. Drones drop Raw Uranium into it, the Fuel Assembler draws from it and returns finished Fuel Rods, and the Reactor pulls its fuel from it.
Stats: Storage 100 units
How to obtain: The recipe unlocks when you complete Helios, Plate Order. Requires the Shielded Logistics research (Oxygen 3,000). Fabricate on a Fabricator: 3× Lead Plate, 1× Machine Frame. Deploy from Inventory.
Access: get_component(id) · Like every component, exposes .id and .name.
Methods
Section titled “Methods”.outpost
Section titled “.outpost”The outpost where this building is deployed, as an OutpostRef.
.count(item_id)
Section titled “.count(item_id)”Units of item_id currently casked. Returns 0 when the cask is empty or latched to the other hot item. Inventory, Storage Bins, and Warehouses expose the same count(item_id) query.
Returns: Number
.fill_percent()
Section titled “.fill_percent()”Fill fraction 0-1: watch your strategic reserve.
Returns: Number (0-1)
.capacity()
Section titled “.capacity()”Maximum hot units (100).
Returns: Number
.material()
Section titled “.material()”What the cask is latched to: "raw_uranium", "fuel_rod", or empty when unassigned. One material per cask, like every stock bin. Casks accept ONLY hot items; everything else refuses them.
Returns: String
.transfer_to(target, item_id, count, properties=None, property_match=None)
Section titled “.transfer_to(target, item_id, count, properties=None, property_match=None)”Requires Auto Feeders research. Move hot cargo to another same-outpost storage endpoint. Hot cargo must move through compatible Lead Casks ("hot_cargo_requires_cask" / "cask_accepts_hot_only" enforce this).
Returns: TransferResult; see that page for the full shared outcome table.
