Guide: Designing A RBMK Reactor

Ok considering how vague the main page was on creating a RBMK, here's a guide to do so

Color coding:

* Green: Fuel Rod
* Orange: Steam Channel
* Black: Moderator
* Grey: Reflector
* Blue: Control rods
* White: Blank

## Neutron Directions

ReaSim fuel rod output 6 neutrons per tick. It doesn't just output diagonally but they output in 6 random directions 360 degrees around it. Do not get fooled

## Temperature

Now, temperature is the most important thing you need to think of when making a RBMK. Temperature can be dissipated more the bigger your RBMK is, though this does not really matter in non-reasim, it matters the most in reasim. RBMKs will ALWAYS meltdown if one of the part's temperature exceeds 1500 degrees, this process is accelerated even further if a fuel rod exceeds their melting point, as they start to melt into the RBMK parts increasing their temperature even further. If a fuel rod exceeds their melting point, good luck saving your reactor. There is a big difference in controlling the temperature of your reactor in non-reasim and reasim.

* In reasim your entire reactor acts as a boiler, producing significantly more energy while being more random, and only producing super-dense steam. To fill with water, put water inlets on one side and steam outlets on the other it should start filling every part with water.
* Non-reasim reactors use steam channels/boilers to control the temperature of the reactor and can be set into 4 modes from steam to ultra-dense steam. Pretty sure filling this is in the main page
* The strategy for reasim reactors is just supply with A LOT of water and fill every empty spot that serves no purpose with blanks to further dissipate heat

## Control Rods

Look at main page

Quick Summary:

100% = absorber

0% = full power

\*These things are the lifeboats of your reactor, use them carefully, and place them optimally like around a self-igniting rod and behind a reflector

## Moderation

~~A **forum moderator** oversees the communication activity of an Internet forum.~~

Moderation is a very important aspect in designing your reactor, most fuels cannot do anything meaningful if it's hit by fast neutrons, excluding Americium-241 and Neptunium-237 which can fission by fast neutrons. Fast neutrons get slowed down by moderators so that it can do funny things with other fuel rods. These neutrons come from "self-igniting" rods like the MEP-239 rod. Moderating in non-reasim reactors if pretty straightforward. However, in the world of **reasim** reactors, you need to fully surround the self igniting rods moderators to achieve optimal results (or simply just make its moderated variant because it's much cheaper anyways). In contrast LES doesn't require moderation between them unless it's receiving fast neutron from a different fuel.

## Reflectors

Reflectors are parts that well, reflect neutrons back. Useful to squeeze more power out from your reactor but gets annoying if you wanna shut it down if the control rod placement isn't optimal. Not advised to be used with dangerous function fuel like MES, Flashgold, Balefire, etc.

## Neutron Absorber

Absorbs neutrons, useful to control the power in a reactor with highly reactive fuels.

## Irradiation Channels

Basically an absorber with the added bonus of being able to make Tritium out of Lithium and Gold-198 out of gold, Thorium fuel out of Thorium and Glowing mushroom stew out of mushroom stew, as said in the main page, fast neutrons are only 20% as effective.

## Cooler

You'll barely ever use this if you know what you're doing, trust me.

Useful for cooling a reactor on its verge to meltdown, other than that it just decrease efficiency for an intentionally designed hot reactor.

## DIGAMMA

**DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA DIGAMMA**

Translation: DIGAMMA is a dangerous particle among us, trolls a world if it explodes in a RBMK reactor with a big sword to top it off. Your world is ruined, but you get to see a cool stick.

## Water

5-6 Heavy infinite water barrels are necessary paired with a closed loop with the big cooling tower for an average reactor.

## Fuels

* Natural Uranium is funny. (it's decent like the one in the zirnox reactor)
* MEU is NU but stronger flux function.
* **HEU235 and MEP239 are staples in RBMK fuels**, easily achieves high flux, cheap, all a designer could ask for.
* LES is a *very good* alternative to HEU-235 as it don't require moderator between it.
* MES and HES are very unstable, be very careful before running it.
* Flashgold and Flashlead are stupidly unstable, don't use if inexperienced.
* MOX is quite powerful here, don't let the big reactor's MOX fool you.
* HEAus is also a good fuel to use, no rads, really cheap if you have a lot of Australium, and high melting point.
* LEAus is also very good for a secondary neutron source with how cheap it is and it doesn't deplete when no external flux is received.
* Americium is very reactive and has very low melting point. But can output large amount of energy if correctly controlled.
* Thorium is almost the same as NU but safer, an excellent driver fuel alongside LEAus.
* Balefire is very good if you can control it.
* Digamma is certainly not very friendly but can be easily controlled by utilize driver fuel.
* **HEU-233 became Linear in version X4263, and instead HEU-235 became identical it.**
