Neptunium Fuel

Neptunium fuel is a special type of fuel utilizable by both the Watz Power Plant and RBMK. The two forms are quite different from each other.

Production
See Neptunium-237 for information on making the element itself.

For Watz fuel, it is simply 5 pure ingots for each pellet.

For RBMK fuel, it can be made by either mixing 1 Neptunium-237 billet with 2 U-238 billets to make 3 billets or 4 U-238 nuggets and 2 Neptunium nuggets to make 1 billet.

Watz Power Plant

 * 216,000 tick estimated lifespan
 * 300 HE per tick
 * +10% power multiplier
 * 25 heat
 * +10% heat multiplier
 * +0.5% decay multiplier

RBMK
Neptunium is a high strength RBMK fuel and is special because it does not require the use of moderators due to fissioning with fast neutrons.

It has a flux function of: $$\sqrt{x} * 45 / 10$$

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

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

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

Watz
All Watz Plant fuel pellets decay into lead.

RBMK
(To calculate with Xenon-135 poison, remove 1% from Neptunium fuel and add 1% to Xe-135)
