The RBMK graphite reactor is an extremely complicated fission boiling water reactor added during the X3864 version.

Rbmk's working principle

Because graphite is a good neutron slower, it is often used to slow down the neutron of the reactor kernel fuel.

After the nuclear fuel occurs chain reaction, the neutron impact to a neutron reflection (dense lead plate/copper-lead alloy) material with a good neutron reflection, and then slow down the movement speed of the neutron after graphite (except that most fuel sticks are mostly fuel sticksThe coefficient also has special cases), which causes the next chain reaction to the next step.

RBMK's nuclear fuel stick

The fuel rod is a nuclear fuel in the RBMK reactor, and they can be placed in the fuel rod for a chain reaction.

RBMK fuel rod type

RBMK fuel rods can be divided into two types: conventional fuel rods and neutron radiation sources.

Conventional fuel rod refers to a fuel rod that can perform a stable chain reaction in the RBMK nuclear reactor and generate power generation.

Neutron radiation sources refer to the fuel rod with Self-Ignition attributes, promoting other fuel rods for chain reactions, spontaneous heat production and chain reactions, and fuel rods with the "S" head. TheyNot suitable for being put in the reactor, because their melting temperature is extremely low, and the neutron type released by spontaneous combustion is their "fission release neutron type" type.

RBMK fuel stick attribute

The two important attributes are the loss and Xenon Posion

The loss is the durability of the fuel rod. After the durability is used, the fuel rod cannot be used.

The key factor affecting RBMK power generation and heat production is the toxic of sannival.

因 Poisoning is one of the most important factor. The degree of poisoning generally refers to the accumulation of a highly captured reaction product "氙 -135" (xenon-135) in the reactor;From the decline of iodine-135, 氙 -135 belongs to neutron poison, and has a large neutron absorption section.If the 氙 -135 exists too much and absorbs too much neutron, the density of the neutron flux will be reduced, the reaction activity will be reduced, and the power cannot be recovered, entering a vicious cycle.This phenomenon can also be called "reactor poisoning".

In this module, the 氙 -135 of the RBMK reactor qi toxic effect generally comes from the long-term low-power running or wrong neutron type selection of the reactor.

RBMK fuel rod neutron type

All RBMK fuel rods have its corresponding fission neutron type.

The type of fission demand refers to the type that wants to make the fuel rod continuously chain reaction. Most fuel rods are slow neutron and a small part is fast neutron.

The fission release neutron type refers to the type of a neutron reaction in the fuel rod that has already performed a chain reaction, and the type of neutron released after the chain reaction. The type of all fuel rods is fast.

Only the matching of the neutron type and fission to release the neutron type of the fission demand of the fuel rod can maintain a continuous chain reaction of a fuel stick.

You can use RBMK Graphite Moderator to slow down the fast neutron to slow neutron.

The calories of RBMK fuel rod

All fuel rods have a data about the temperature and core temperature of the shell, which represent the current thermal value of the fuel rod and heat production.

These fuel stick data is also related to an important data called Melting Point. Once any of the two of the above two exceeds the melting point of the fuel rod, then the fuel rod with the fuel stick will be a fuel stick.There is a certain probability of melting. Of course, the general core temperature is not easy to surpass the shell temperature.

RBMK reactor part

The composition of the RBMK reactor is the following 9 parts:

RBMK fuel stick

RBMK steam storage tank

RBMK control stick

RBMK automation control stick

RBMK graphite neutron slower device

RBMK TUNGSEN Carbide Neutron Reflector

RBMK boron neutron absorber

RBMK structure column

RBMK controller

RBMK fuel rod (RBMK Fuel Rod)

It is one of the most important core components in the entire RBMK reactor. It is a component used to make RBMK fuel rods, and it is also a component of heat.

Red: The state of the reactor, if there is a fuel rod inside, is displayed as green, if not, it is displayed as the figure above.

Yellow: Insert the position of the reactor fuel rod.

Purple: The degree of poisoning of a fuel rod is that the fuel rod uses the wrong neutron type/continuously running at low power (no sufficient neutron reflection to nuclear fuel) will be produced.The lower the thermal efficiency, and the chain reaction will also stop.

RBMK steam storage tank (RBMK Steam Channel)

Like RBMK Fuel Rod, RBMK Steam Channel is also an important part.

Its role is:

Take away the excess calories of the adjacent RBMK Fuel ROD components to generate steam, that is, power generation

Gui is as follows:

Red: Set the type of production of steam, from top to bottom, from (quality) high to low divided into: steam (100 ° C), thermal steam (300 ° C), ultra -heat steam (450 ° C), and ultra -thick steam (600 ° C), can only produce one steam at the same time. Right -click the area in the red border to adjust the steam type.

Green: The steam cache, the RBMK Steam Channel provides its own large cache of 100000MB of steam in each type of steam.

Blue: Water cache, RBMK Steam Channel provides a water cache of 10,000MB.

RBMK control stick (RBMK Control Rods)

An important element in the RBMK reactor is used to suppress and control the number of neutron reactions released by the chain reaction of the RBMK Fuel ROD kernel fuel.If you are high, you should immediately adjust the control stick of the RBMK Control Rods adjacent to the reaction room to 0%.

The figure below shows GUI:

Red: It represents a color group that controls the rod, which can control a bunch of fuel rods in the RBMK controller more portable, and distinguish is not very necessary.

Green: The degree of control of the control stick can show a specific value of the rising control stick (percentage)

Fan: You can adjust the degree of raising of the control stick, with five levels: 0%, 25%, 50%, 75%, and 100%.

RBMK automation control stick (RBMK Automatic Control Rods)

The same role as the control stick, but the difference is that it can detect the temperature of the adjacent fuel rod, and automatically control the control rod to rise.The figure below shows GUI:

Red: In order to set the main features of RBMK Automatic Control Rods in order to set the reactor heat, heating curve, and storage position.

Green: The same control rod can see the current RBMK Automatic Control Rods from the green area.

RBMK graphite neutrophil (RBMK Graphite Modrator)

With its name, the role of RBMK Graphite Modrator is to make most of the fast neutron released by most fuel rods in the adjacent RBMK Fuel Rod, which is used for most of the slower neutron fuel rods, and the error is used.Type neutrons for fission can cause the ricorization coefficient of a fuel rod to increase.

Therefore, it is an important part of the RBMK reactor.

However, some fuel rods (such as MEN fuel rods) that cause fission are the same as the type of neutron (all slow neutron), that is, no neutron slowness is required.

It has no GUI.

Tungsten tanton reflex components

The name has been very concise: Neutron Reflector. The role of this component is reflecting neutron to nuclear fuel. It is composed of all fuel rods without this part.Part of the part will be distributed outside the area where the nuclear fuel generates chain reaction.

But if you place too much RBMK TUNGSEN Carbide Neutron Reflector, the reaction heap is melted.

Like RBMK Graphite Modrator, it has no GUI.

RBMK boron neutron absorption component (RBMK BORON Neutron Absorber)

Like the name, absorb neutron.

When building an RBMK reactor, multiple different fuel rods may be used, and the types of fuels in the internal installation may be different. So how to solve this problem?The figure below is an example:

Assuming that in the figure above, the PO210BE fuel rod is installed in the A fuel rod. We need to use its spontaneous combustion attributes to ignite other fuel rods to promote the occurrence of chain reactions.

We want to make the MEN fuel rod in the C fuel rod in a chain reaction without wanting the E fuel rod with the MOX fuel rod to cause a chain reaction. It only needs to replace the B position to the RBMK structure column, replace the E position to RBMKBoron Neutron Absorber can solve this problem. Of course, the actual problem may be much more complicated than this.

No GUI.

RBMK structure column (RBMK Structural Column)

The RBMK structural column does not have any effect on the chain -type reaction. Instead, it acts as the role of transmitting neutron between the two fuel rods in the two regions in the previous problem, and sometimes it can also be used to dissipate heat and transmit heat.

No GUI.

The RBMK Irradiation Channel RBMK radiation warehouse is a component added to the 1.027x3892 version. It can be transformed into another material by the heating neutron, similar to the proliferation reactor.

Huang: Enter the bar, put items you need to proliferate.

Red: Output a pyramid field, cache 64000MB of liquid 氚.

Green: Output bar, output solid -state items.

Available synthesis: Gold ingots → Gold-198 ingots, Lithium ingots → 氚

Do not use NEI query synthesis.

RBMK controller (RBMK CONsole)

The RBMK controller is a type of control device that controls the chain reaction of the entire RBMK graphite nuclear reactor. It is a very important existence (but may be available).

The outside scene is as follows:

It can control the temperature of the reactor and even the temperature of the reactor within the scale of a 15x15, and the control rod lifting, and even the famous AZ-5 button !!!!Similarly, all the control rods in the control range can be reduced to 0%, that is, closing the reactor.

It can also divide the reactor into several color groups to better manage different parts. The figure below is GUI:

Red: The temperature control system and control rod system of the group.

Green: Quick management of color groups.

Green: The height of the regulating control stick can be filled in, such as 25, 50, 75, 100, etc.

Blue: The AZ-5 button (the "A3-5" button may be due to Russian). After pressing, all the control sticks in the control range can be dropped.

Fan: All components related to the RBMK reactor in the range of 15x15, if you move the cursor on a component, you can see basic information such as the heat, the amount of steam, the speed of the steam, the amount of water, and the heating level per minute.
