The '''Fast Breeder Reactor''' is a machine that generates large amounts of {{infoicon|SteamSp|text=Steam (Super)|link=Steam (Super)|new=yes}} from {{infoicon|Water}} and {{infoicon|Core Fuel|new=yes}} for use in generators. The reactor can also enrich {{infoicon|Blanket Fuel|new=yes}} to {{infoicon|Blanket Fuel (Enriched)|new=yes}}, which is used in the production of {{infoicon|Core Fuel|new=yes}} and other nuclear products.

Because of this, it is only necessary to produce enough initial {{infoicon|Core Fuel|plural=|new=yes}} from a [[Chemical Plant II|Chemical plant II]] to begin the loop, as long as you are recycling the spent core fuel and enriched blanket fuel. Once this cycle is operating successfully, you will only need to make sure that you continue adding a small amount of {{infoicon|Blanket Fuel|new=yes}}, which can be easily made from a relatively small amount of {{infoicon|Yellow Cake|new=yes}} with no {{Infoicon|Depleted Uranium|new=yes}} byproduct.

Power is generated by passing the output {{infoicon|SteamSp|text=Steam (Super)|link=Steam (Super)|new=yes}} through [[Super-pressure Turbine]]s, [[High-pressure Turbine]]s, and [[Low-pressure Turbine]]s with their output shaft connected to [[Power Generator]]s, typically Tier 2 variants of each. A majority of the Water can subsequently be recovered for reuse using a [[Cooling Tower (Large)]].
Generated {{infoicon|SteamSp|text=Steam (Super)|link=Steam (Super)|new=yes}} can be also used to [[Thermal Desalinator|desalinate]] {{infoicon|Seawater}} and produce {{infoicon|Hydrogen}}.

== Core and Blanket Fuel ==

=== Core Fuel ===
{{infoicon|Core Fuel|new=yes}} is the primary fuel used by the Fast Breeder Reactor and is required for it to operate. An equal amount of {{infoicon|Core Fuel (Spent)|new=yes}} is produced as the result, which can be reprocessed in a {{infoicon|Nuclear Reprocessing Plant|new=yes}}.

{{infoicon|Core Fuel|new=yes}} in a running reactor loop typically does not need to be externally provided. For initiating a loop however a minimum of 40 should be provided so the reactor can begin to work, for which both {{infoicon|Plutonium|new=yes}} and {{infoicon|Enriched Uranium (20%)|new=yes}} can be used.

Reprocessing of {{infoicon|Core Fuel (Spent)|new=yes|text=Spent Core Fuel}} returns 75% of the amount as {{infoicon|Core Fuel|new=yes}} alongside a {{infoicon|Fission Product|new=yes}} by-product.

=== Blanket Fuel ===
{{infoicon|Blanket Fuel|new=yes}} is an optional input fuel for the reactor. While it does not contribute to power generation, it can be enriched into {{infoicon|Blanket Fuel (Enriched)|new=yes}}, which can in turn be used to produce {{infoicon|Core Fuel|new=yes}} to sustain the reaction or to produce other nuclear products.

{{infoicon|Blanket Fuel|new=yes}} is typically produced from {{infoicon|Yellowcake|new=yes}}, though {{infoicon|Depleted Uranium|new=yes}}, {{infoicon|Spent Fuel|new=yes}} and {{infoicon|Spent MOX|new=yes}} as by-products of earlier nuclear power production chains can also be used to produce it.

The enrichment of {{infoicon|Blanket Fuel|new=yes}} is optional. The reactor's {{infoicon|SteamSp|text=Steam|link=Steam (Super)|new=yes}} production and {{infoicon|Core Fuel|new=yes}} consumption are not affected if {{infoicon|Blanket Fuel|new=yes}} is not provided or {{infoicon|Blanket Fuel (Enriched)|new=yes}} is not removed.

Reprocessing of {{infoicon|Blanket Fuel (Enriched)|new=yes}} returns 75% of the amount as {{infoicon|Blanket Fuel|new=yes}} and the rest as a secondary product of choice.

== Enrichment options ==
The Fast Breeder Reactor has three modes of enrichment:

0: Enriches no {{infoicon|Blanket Fuel|new=yes}} and halves {{infoicon|Core Fuel|new=yes}} consumption. Not recommended unless you have a lot of {{infoicon|Plutonium|new=yes}} to spend.

1: Enriches as much {{infoicon|Blanket Fuel|new=yes}} as {{infoicon|Core Fuel|new=yes}} consumed. This mode creates a zero-sum loop where only {{infoicon|Blanket Fuel|new=yes}} needs to be provided and {{infoicon|Fission Product|new=yes}} to be removed, and is ideal for power generation.

3: Enriches trice as much {{infoicon|Blanket Fuel|new=yes}} as {{infoicon|Core Fuel|new=yes}} spent and cuts {{infoicon|SteamSp|text=Steam|link=Steam (Super)|new=yes}} production by 75%. Used to produce {{infoicon|Plutonium|new=yes}} and {{infoicon|Enriched Uranium (20%)|new=yes}} for space-related parts.

Below are the recipes for all three operating modes at 1x and 4x reactor speed.
