The Uranium Cell is the main component of nuclear fission in a Nuclear Reactor. Every Uranium Cell has the potential to produce enormous amounts of energy, between 2-10 million EU. However, during the process of fission, the Cell generates excessive amounts of heat, which must be eliminated by the use of different cooling elements.

The Uranium Cell can be obtained either by combining Refined Uranium with an Empty Cell, or combining a Re-Enriched Uranium Cell with Coal Dust.

Uranium physics (v1.106+)[edit]

Used variables:

  • n: Nearby uranium cells (by "nearby" I mean one slot horizontally or vertically)
  • p: Amount of pulses this reactor tick
  • h: Heat produced this reactor tick
  • e: Energy produced this reactor tick
  • c: Amount of cells in this item

A uranium cell will always pulse once plus the amount of cells that are directly adjacent (and contain uranium):

  • P = 1 + N

Addition: To compensate Dual (C = 2) Or Quad (C = 4) cells you should use:

  • P = 1 + (C / 2) + N

A single Uranium Cell will always create Heat and Energy based on how often it pulses per reactor tick:

  • H = 2 * P * (P + 1)
  • E = 5 * P

Addition: To compensate for Dual and Quad cells you should use:

  • H = 2 * C * P * (P + 1)
  • E = 5 * C * P

Coolant physics in 1.106+[edit]

As uranium reactions produce heat and coolant is what you need to not let your reactor melt. In order to do so you can use one of these:

  • The coolant cell. There are 3 types of coolant cells which can store up to 10K, 30K or 60K heat and you can get that heat out again. Be careful tough, as it will break when being heated beyond the max heat value.
  • The condensator. There are 2 types of the condensator, the RSH (20K) and the LZH (100K). They are pretty much coolant cells but can store more heat, will not break when reaching their heat cap but you can still get the heat out again.

Additionally you can "repair" them using redstone (and lapis for the LZH). Redstone fills up a RSH by 10K a LZH by 5K and lapis fills a LZH by 40K.

  • If you want to heat the reactor instead, you can use a heating cell. They stack to 64 and heat every adjacent component by stack size until it reaches stack size * 1000.

Heat switch physics in 1.106+[edit]

Heat switches distribute the heat of themselves, the reactor and the nearby components, until they all have the same heat compared to their respective max heat.

Used Variables:

  • Tm: max heat
  • Ts: side heat transfer rate
  • Tr: reactor heat transfer rate

There are 4 types of heat switches or heat exchangers:

  • The (normal) heat exchanger.
    • Tm = 2500
    • Ts = 12
    • Tr = 4
  • The advanced heat exchanger, which is just the upgraded version of the normal one.
    • Tm = 10000
    • Ts = 24
    • Tr = 8
  • The component heat exchanger, it only transfers heat between nearby components and itself.
    • Tm = 5000
    • Ts = 36
    • Tr = 0
  • The reactor heat exchanger, it only transfers heat between the reactor and itself.
    • Tm = 5000
    • Ts = 0
    • Tr = 72

Heat vent physics in 1.106+[edit]

Heat vents are basically heat switches that additionally cool themselves down. They will however not give their heat away by themselves, you have to take it away using other elements. There are 5 types of heat vents that are similar to the heat switches except for the overclocked one as it is new: Used Variables:

  • Tm: max heat
  • Tr: reactor heat transfer rate
  • Tc: the self cooling rate

The types of switches are as follows:

  • The (basic) heat vent that only vents heat it has stored.
    • Tm = 1000
    • Tr = 0
    • Tc = 6
  • The advanced heat vent which is again a better version of the basic one.
    • Tm = 1000
    • Tr = 0
    • Tc = 12
  • The overclocked heat vent which is the fastest but also gets destroyed pretty fast if it always finds heat.
    • Tm = 1000
    • Tr = 36
    • Tc = 20
  • The reactor heat vent takes the heat only out of the reactor again.
    • Tm = 1000
    • Tr = 5
    • Tc = 5
  • The component heat vent takes the heat only out of components again.
    • Special case: it removes 4 heat from every nearby component each tick and can not store heat.

Conclusion[edit]

  • Uranium cells:
    • Basic Formulas:
      • h = 2 * c * (1 + floor(c / 2) + n) * (2 + floor(c / 2) + n)
      • e = 5 * c * (1 + floor(c / 2) + n)
