Fissile Fuel Cell Engine

A Fissile Fuel Cell Engine is essentially a Fuel Cell Engine designed specifically and exclusively to work by producing electrical energy from the radiactive decay of high energy atoms such as Plutonium.

Fissile Fuel Cell Engines are rare due to the nature of this type of fuel, that normally has to be artificially enriched beforehand.

Rules
They are very fuel efficient and don't explode, but are expensive.


 * Fissile Fuel Cell Engines need 2 heatsinks. They come integrated in the case of vehicles.
 * Fissile Fuel Cell Engines don't have a conventional "fuel tank" that can be critted.
 * Plutonium cells give 3000 km of operative range. Extra cells can be added to a design, occuping 1 crit slot and weighting 10 percent of the engine weight.
 * Fissile Fuel Cell Engines are 10% heavier than conventional Fuel Cell Engines.
 * Fissile Fuel Cell Engines are 15% more expensive than conventional Fuel Cell Engines.
 * Fissile Fuel Cell Engines require power amplifiers to work with high-energy weapons (unlike Fission Engines), since radiactive materials decay slowly and this is not a reactor.
