Uranium Fuel

Uranium fuel is perhaps the simplest nuclear fuel to produce. It is usually the first fuel a player will make for their reactor when leaving the fossil fuel stage. It is also usable in the RBMK and ZIRNOX GCR as a mid-strength fuel.

Production
It can be made right after a Uranium Hexafluoride batch is done processing as the materials needed all come from there.

Using that method directly, it is made with 5 U-238 nuggets and 1 U-235 nugget to make a billet.

ZIRNOX
Medium enriched Uranium fuel provides 50 heat/tick and has an estimated lifespan of 100,000 ticks.

Small Reactor
Uranium fuel rods produce 15 heat and have a 100,000 tick lifespan.

Heat statistics for the small reactor, being filled with 12 (complete fill) of each rod type and temperature counted in degrees Celsius (no external modifiers used):

Large Reactor
Heat statistics for the large reactor, checking every operating level and temperature checked in degrees Celsius:

RBMK
MEU RBMK fuel is a mid-strength fuel that is craftable, but not recyclable yet.

It has a flux function of: $$\log_{10}(x + 1) * 0.5 * 20$$

The function is considered medium danger and is of the "Logarithmic" type.

A Xenon-135 generation function of: $$x * 0.5$$

And a Xenon burn function of: $$x^2 * 50$$

ZIRNOX & Generic Reactor
Spent fuel emits 40 RAD/s per "piece" when hot and 30 RAD/s when cooled.

When recycled, it gives 1 Plutonium nugget, 1 Reactor Grade Plutonium nugget, 1 Technetium-99 nugget and 2 tiny piles of nuclear waste.

(To calculate with Xenon-135 poison, remove 1% from Uranium fuel and add 1% to Xe135)

Uses

 * Uranium fuel can be used in both small and large nuclear reactors, as well as the RBMK.
 * Producing Plutonium either for more advanced fuel or for nuclear weapons.


 * 2 Uranium Quad Fuel Rods are used to make and power the Mk.I FOEQ Duna Space Probe because it uses an experimental nuclear propulsion system.


 * Will reward you with the Bobmazon Atomic Science achievement when crafted.
 * Ingots are used in the recipes for BF Rocket Fuel thrusters.
 * Curiously, the recycling recipe only yields 5 nuggets instead of 6.

Trivia

 * Technically has a net positive fissile matter consumption over production, though it is in the form of Plutonium, instead of Uranium-235.
