Nuclear Reactor/Legacy

The Nuclear Reactor is a multi-Block EU generator added by IndustrialCraft 2, with GregTech and nuclear Control adding more funcionality to it. It is possible to let the Nuclear Reactor generate Steam in the IC2 config file. The nuclear reactor is, especially when GregTech is enabled, not a very expensive machine, but it is tricky to operate and difficult to get significant amounts of EU out of it without exploding.

The Nuclear reactor consist of 2 parts:
 * 1 Nuclear Reactor
 * 0-6 Reactor Chambers

The Reactor Chambers can be placed against the sides of the Nuclear Reactor to increase it's inventory space and thus increasing the power. This structure is often referred to as 'core' or 'reactor'. This is only a empty hull though, to render the reactor operational fuel and reactor components need to be placed inside it

Reactor Terminology
To understand how a reactor works and to know how to build one yourself, these terms are important to know

Reactor Tick
Not to be confused with Game Tick (1/20th of a second) Every second, the reactor updates it heat, cell durability and so forht. This update is called a Reactor Tick.

Heat
A Reactor produces 2 things, Heat and EU. This heat generation is what makes a reactor tricky. Every fuelcell generates heat, depending on type and location of other cells. Other components like Heat vents cool the reactor down again. If the heat value reaches a certain level, a reactor meltdown will happen. The ratio heat produced/heat dissipated determines the reactor type

Pulse
Every tick, a fuel cell pulses, generating heat and energy. How many pulses it gives is determined by the amount of other fuel cells and reflectors directly around it.

Cycle
A Cycle is the time it takes for a reactor to fully deplete it's cells. This varies per fuel type:

Reactor Design
There are a lot of different Reactor designs. These are dividable in 2 main different designs:

Power
A reactor meant to generate EU, trying to be as efficient in it as possible related to time, components and fuel.

Breeder
This reactor is ment to revitalize Depleted Isotope Cell. To do so the reactor tries to have an as high as possible heat level without exploding.

Power Generating Reactor
This reactor is meant to output as much EU as possible. It can be split up depending on it's heat generation:

Mark I
Mark I reactors generate no excess heat each reactor tick and thus are safe to use continuously for as long as you supply Uranium. Mark Is tend have a low efficiency, but that's the price of a completely safe reactor. Mark Is have two sub-classes: Mark I-I for design that do not rely in outside cooling in anyway and Mark I-O for those that do.

Mark II
Mark II designs produce a small amount of excess heat and will need to be given a cool down period eventually to prevent the hull reaching 85% maximum heat or melting component. A Mark II must complete at least one full cycle before encountering heat problems. The sub-class for Mark IIs denote how many cycles the design can run before reaching critical heat levels. For example Mark II-3 will need a cool down period after running 3 cycles in a row. Mark II s that can run 16 times or more get the special sub-class 'E' (Mark II-E) for almost being a Mark I.

Mark III
Mark III reactors tend to have an emphasis on efficiency at the cost of safety. Mark IIIs are unable to complete a full cycle without going into meltdown and thus need to be shutdown mid-cycle in order to deal with the high amount of excess heat. This can be done manually or by using Redstone. Mark IIIs have the additional condition that they must run at least 10% of a cycle (16 mins 40 secs) before reaching critical heat or losing any components.

Mark IV
Mark IVs still have to run at least 10% of a cycle, just like Mark IIIs. The difference being that Mark IVs are allowed to lose components to overheating, and that must be replaced before the reactor goes critical.

Mark V
Mark Vs are for those who want to squeeze every last scrap of EU from their uranium cells; they cannot run long without needing a cool down period. You'd better have great Redstone timer skills, or you'll never be able to turn your back on these things.

Breeder suffix
This suffix is for designs that also recharges isotope cells. Isotope cells charge up faster when the reactor runs hot, so heat management is important. There are three breeder types: Negative-Breeders slowly lose heat over time and will need heat to be added manually, or they can be left for a safe slow way to recharge isotopes. Equal-Breeders have exactly the same heat generation as they do cooling ability and usually only require a user to boost the reactor's heat level manually at the beginning. Positive-Breeders gain heat over time and will require more precise cool down management for the reactor to remain hot. Reactors whose sole purpose is to recharge cells may not even have a 'Mark' classification and are simply called Breeders instead, with the efficiency/SUC suffix added

o calculate efficiency, take the number of uranium pulses a design makes per tick and divide it by the number of uranium cells it possesses. The number provided will show the efficiency rating a design has:

Breeding Reactor
A reactor purely meant to revitalize Depleted Isotope Cells.The time it takes to revitalize the cell is determined by the. Most breeders have components to increase the maximum hull temperature and try to stay as low as possible below that. Reactor Ticks required to fully revitalize a Depleted Isotope Cell

In order for a Breeder reactor to work the Depleted isotope needs to be placed next to a fuel cell. If more fuel cells are next to it, the Isotope cell charges faster. 2 fuel cells mean the Isotope cell charges twice as fast, 3 fuel cells and the isotope cell charges 3 times as fast. This also counts for double and quad cells, meaning a quad cell will charge 4 times as fast. The varying power Plutonium and Thorium Cells also work different. Plutonium cells are twice as powerful as uranium and thus charge twice as fast, and thorium cells thus twice as slow. The maximum speed is a Depleted Isotope Cell surrounded by 4 Quad Plutonium Cells, being 16 times as fast as the base speed in the table above. Isotope Cells also generate additional heat like normal cells would when placed next to fuel cells, but not EU. Re-enriched energy cells are stable and won't cause any extra heat production. For more detailed information about heat production, see the Heat Production.

Heat Vents
The Heat vent allows for fast cooling, releasing the heat into the air.
 * Heat Vent: The basic vent dissipates 6 heat from itself every second.
 * Reactor Heat vent: This vent moves 5 heat from the reactor vessel to itself and dissipates 5 heat every second. This has the advantage that it can function effectively anywhere in the reactor, not just next to the uranium cell.
 * Advanced Heat Vent: An improvement to a basic heat vent, this component dissipates 12 heat from itself.
 * Component Heat Vent:This vent dissipates 4 heat from each surrounding component.
 * Overclocked Heat Vent:This vent moves 36 heat from the reactor to itself and then dissipates 20 heat from itself. This will cause the component to overheat if steps are not taken to cool this component.


 * heat dissipated=Amount of heat released every tick.
 * Heat pulled From Reactor=Amount of heat pulled from the reactor. If this is 0 the heat vent can't actually cool down the reactor. In order for this heat vent to work it needs to be placed directy next to a cell. It will take ALL the cells heat. (if this is more that the dissipasion rate the heat vent will melt.
 * maximum heat = maximum heat it can store before smelting.

Heat Exchangers
Heat exchangers do not dissipate heat or actively draw heat from other objects, but they transfer the heat they get from other components like cells transfer around, making it easier for other components to dissipate. Heat exchangers work intelligently, seeking to make every component they interact be equally far from disintegration.

For instance, if a basic heat exchanger (which is destroyed at 2500 heat) was transferring heat from itself to the reactor (which usually is destroyed at 10 000 heat), and the heat exchanger contains 1,250 heat, it gives the reactor 1000 heat (10% of the reactor's capacity) and itself 250 heat (10% of its capacity).

There are four types.
 * Heat Exchanger: These will first exchange up to 12 heat with each surrounding component, and then up to 4 with the reactor itself.
 * Advanced Heat Exchanger: These transfer up to 24 heat with each surrounding component, and then up to 8 with the reactor.
 * Reactor Heat Exchanger: These transfer up to 72 heat with the reactor, put will not move heat to or from nearby components. These will usually be at the same percent capacity as the reactor, so they are useful as a kind of thermometer for your reactor.
 * Component Heat Exchanger]]: These transfer up to 36 heat with each adjacent component, but does not transfer any with the reactor itself.

Cooling Cells and Condensators
Cooling Cells and Condensators have the ability to absorb large amounts of heat, but cannot dissipate or transfer it by them selves. If Coolant Cells Reaces their maximum heat, they melt, but Condensators way stay at 1 durability, but renering it useless. They can be cooled down inside a reactor via heatvents More To Come
