This tutorial is set by the author's setting without permission.

RBMK is the most distinctive reactor in HBM, but most tutorials aims to introduce the function of the structural column, the basic principles of the reactor (that is, the guidance of the own), and the setting of some simple RBMK.The tutorial you can see can only be written by yourself.

The MC version of the tutorial is 1.7.10, and the MOD version is 1.0.27_x5027.In addition, I am an automated residue, so there will be no discussions related to RBMK automated input and output here.

Cool for reactor

If you want RBMK to run stably, strong heat dissipation is essential. Let's talk about heat dissipation.The structural column of the reactor heat dissipation has RBMK steam pipes, RBMK fluid heater and RBMK cooler. The latter is not familiar, so I won't say it here.

Steam pipeline

Steam pipes can output four types of steam: steam, hot steam, ultra -heat steam and ultra -thick steam.The four types of steam exchanges are multiplied by 10 in turn.And the conversion of water and low -voltage steam is 1: 1, which has important reference significance for the choice of heat dissipation.

Water: Super strong = 1: 0.1

Water: Ultra -heat = 1: 1

Water: Hot steam = 1:10

Water: Steam = 1: 100

Water: Low -voltage steam = 1: 1

Under the condition of low calories, you can use the electric pump to match the drainage port without water circulation.You need to grasp the number of liquid ports to avoid low -voltage steam burst.

The other is to use the condensed tower to cool down the low -voltage steam. Because the output of ultra -thick steam and ultra -thermal steam is not high, it is more important to pay attention to the output of low -voltage steam and steam.Of course, you can also directly Livatt+electric condensate. For example, the output of the fusion reactor is 600MB/T ultra -thick steam, so the output of low voltage steam is 6kMB/T, and the steam is 600kMB/T. It requires 1 cooling tower.6 industrial steam turbines.The number of calculators cooling tower is secondary. It is important to grasp the conversion of the steam series, which is of great benefit to understanding the steam system that understands HBM.

Liquid heaters

The liquid heater can heat the liquid described by Heatable. Depending on the heat capacity of the liquid, the heating speed is also very different.Taking the steam as an example, except for the three super three steams, they can be heated, but the efficiency is not as good as entering the boiler to boil high, and the heat capacity is also unsatisfactory. Therefore, it is not recommended that the RBMK heater heating steam series.

The thermal Capacity above here refers to this type of steam heated to the TU required by the next level. The Thermal Capacity below refers to the TU that will be released to the next level. Like the ultra -dense steam cannot continue heating, there is only one thermal capacity.It is the Tu released by cooling, and the water is vice versa.After calculation, 1MB of water becomes super thick and will absorb 300TU calories (the official Wiki introduction is a real pit father).Emphasized as coolant.By the way, the strongest combination of heat exchange is blood and blood, and the heat capacity is as high as 500TU.

Usually use the coolant as the medium to heat the heat, turn the thermal coolant into a coolant, and then heat any device you want to heat, usually heating the boiler.

Without considering the power generation, it is already the optimal solution to heat dissipation. Because the heat exchanger can manually set the input, the upper limit of a horror input of 24000MB/T, the heat control is completed, and the expansion is simple. The most important thing is that it is not yet.It will explode.This is also a topic that can be launched with the use of heat exchanges+boilers. You can go out another tutorial in the future, and I won't go into details here.

Fuel stick

We assume that your reactor already has a very strong heat dissipation, and the heat dissipation system of the reactor will never have enough water, the wheelblapper blocking various problems, and then we will conduct the following content.Let's take a look at the prompt of the fuel rod:

Spontaneous combustion: It refers to spontaneously launching neutrons without accepting neutron.

Fuel consumption: The degree of fuel consumption, the fuel core block obtained after cooling according to the degree of consumption is also different.

Fission requires/after fission and release: literal means.

度 Element accumulation/generate function/combustion function: In the case of too much neutron acceptance, it will cause fuel rod ingredients to accumulate, commonly known as poisoning.Generally, the element does not accumulate when the fuel rod is fully burned, which can be ignored.

The neutron radiation function/function type: The independent variable X is the current slow/fast neutron weight, and the calculated value is changed according to the need to change the fission of the fuel rod.The coefficients of the radiation function of some fuel rods will increase or decrease with the consumption of fuel, so pay attention to this when designing, so as not to melt unnecessary.

Surface temperature/melting point: The surface temperature reaches the melting point will explode.

Core temperature: According to the continuous increase in the continuous increase of neutron weight, the actual effect is not great.

In the RBMK running RBMK, the fuel rod always shoots a neutron to the four planes. At this time, the neutron shot from the reflected fuel rod allows it to return to itself.The release of fuel rods increased as the neutron increased, and the slower the growth, the safer.The following figure is a neutron radiation function of the three fuel rods.

critical

If a certain amount of neutrons are provided or reflected, the reactor will reach a critical state.Take LES as an example to make a simple reactor.We put a LES in a fuel rod. Since the slow neutron is released after the fission, we can see the reflection on all sides. You can see that the slow neutron is stable at about 400. According to the radiation formulaA neutrons shot in a direction are about 100. The smart partner has found that its critical point is the intersection of Y = 1/4X and neutron radiation formula.At this moment, the neutron of the fuel rod will return to him next moment, so it will reach a critical state when the neutron is 4 times the release of the neutron.In the same way, the situation of reflection, two sides, and three sides will be different.For linearly growth fuel rods (usually Dangerous), FACTOR similar to GT6 fuel rods, when the accumulation of the coefficient K of the reflex surface N and the neutron radiation function is larger than 1, at this time the reactor is a supercritical state, neutron childThe flux will increase indefinitely.

Taking HEP241 as an example, its radiation function coefficient is 0.4, and the release of the neutron to the original neutron through three sides is 1.2 times the number of neutron numbers.By controlling the initial input neutron with the automatic control rod, it can play an unexpected effect.(It may also be an unexpected explosion (sad))

Neutron source

There are 3 types of neutron sources, namely 钋 210-铍 铍 子, Radium 226-铍 铍 子 中, 钚 238-铍 铍 子 中.Among them, 226 and 210 neutron radiation functions are constant. Taking the radiation function as 20 radium 226 neutron source as an example, the neutron source is 60 after three -sided reflection, which is well understood.Because the radiation function of the 钚 238 neutron source is not a constant, it will involve the calculation of neutron radiation.

Due to the low melting point of these three neutron sources, the radium 226 melting point is only 700 ° C, and the other two are only 1287 ° C, which is lower than the melting temperature of the shell 1500 ° C.In the high -end RBMK reactor, the neutron source will only start the ignition effect as the neutron source in the research heap.

The neutron source also has an upgrade process.The initial neutron source is radium 226, and the nuclear products that extract radium 226 can get 钋 210, and the nuclear products with uranium 235 can be obtained by 钚 238.Here is a special LES. Although the name of the LES is called a fuel rod, the fission is released slowly, and the melting point is high, and the critical point is relatively safe.select.
