Uranium Waste

Uranium Waste is a radioactive byproduct of s created by burning Uranium Fuel Rods. It can be reprocessed into Plutonium Fuel Rods. It is one of the few items that cannot be discarded with the trash button in containers or the inventory.

A single Nuclear Power Plant will produce 50 barrels of Waste every 300 seconds.

The current maximum production rate of Uranium Waste is 2520/min

Resource acquisition
Lizard Doggos can bring single barrels of Uranium Waste at any game stage, which can be especially dangerous before the required equipment or infrastructure to handle it is available.

Crafting
Note: The crafting process of this item is only in the Nuclear Power Plant.

Dealing with Uranium Waste
Uranium Waste cannot be fed into an AWESOME Sink, (legitimately) deleted or destroyed; it must be stored indefinitely or reprocessed into Plutonium Fuel Rods.

It is advised to reprocess it rather than store it. Reprocessing into Plutonium Fuel Rods and burning them creates Plutonium Waste at a slower rate than the Uranium Waste it was made from. Alternatively the Plutonium Fuel Rods may even be sunk eliminating any type of waste entirely.

If the Uranium Waste is stored instead, it is advised to build the waste containment in a remote location, as the radiation spread can reach even 400 meters in radius. The barrels stack to 500, which allows for 12,000 (20 hours per Nuclear Power Plant) to be contained in a Storage Container or 24,000 (40 hours per Nuclear Power Plant) in an Industrial Storage Container.

Removing Uranium Waste
Two known ways to delete Uranium Waste without save editing are as follows:

Doggo deletion

 * 1) Find and tame a Lizard Doggo
 * 2) Feed it a full stack of Uranium Waste
 * 3) Kill it, effectively deleting its inventory contents

Cochrane cannon:

 * 1) Build a Hyper Tube cannon powerful enough to make an extremely rapid exit out of the map boundary; the cannon should be aimed at 45° to gain maximum travel.  23 Hyper Tube Entrances with a mk5 conveyor feed have proven adequately powerful.
 * 2) Empty your inventory and remove any equipped items.
 * 3) Equip a Hazmat Suit and carry a small number of filters.
 * 4) Fill your remaining inventory space with Uranium Waste.
 * 5) Enter the cannon; this will result in the engineer being killed very quickly by boundary damage.
 * 6) Respawn at the HUB and repeat steps 2-5 as many times as required.

Using a save editor reveals that, if done correctly, no death crate containing the waste will be spawned either at the boundary, the cannon position, or anywhere else on the map.

Please note that both ways of deleting Uranium Waste are likely not intended and may be patched out eventually.

Vehicles
Loading Vehicles with Uranium Waste and dropping them into the void might seem as a logical solution, however, doing so is greatly counterproductive. Dropping a vehicle into the void will cause it to fall forever, which degrades game performance, it should therefore be avoided at all costs.

Under the map
An alternative location to store Uranium Waste is underneath the map, where a large distance from the radiation sphere can be achieved without losing valuable legitimate map area. However, this is especially dangerous given game updates can change the terrain and make it impossible to go under.

History

 * Patch 0.4.0.11:
 * Halved Uranium Waste output from Nuclear Power Plant (from 20 to 10 per minute).
 * Halved Uranium Waste usage on all relevant recipes so the ratios remain the same:
 * Non-fissile Uranium: 75 to 37.5 per min
 * Fertile Uranium: 50 to 25 per min
 * Plutonium Pellet: 50 to 25 per min
 * Radioactivity is again doubled (5->10) due to the above changes.
 * Patch 0.4.0.0: Renamed from Nuclear Waste to Uranium Waste. Uranium Waste radiation also reduced to 25% (20->5), at the cost of 4x waste produced per fuel rod. Can now be sorted by Smart Splitters and Programmable Splitters once Particle Enrichment is unlocked.
 * Patch 0.2.1.4: Fixed typos in the trash message
 * Patch 0.2.1.1: Nuclear Power Plants now produce waste over time instead of all at once after a Fuel Rod is consumed
 * Unknown intermediate patch: It can now be brought by Lizard Doggos
 * Patch 0.1.16: Added some feedback when trying to delete with the trash slot
 * Patch 0.1.14: Made officially available
