1. Basic components
Playing RBMK involves a certain mathematical operation, friends with poor mathematics can use calculators or https://www.wolframalpha.com/
1.1 fuel stick
The description is like this, from top to:
name.
The degree of fuel rods has been consumed.The higher this level, the worse the ability to react.The waste recycling requires at least 10%.
氙 Poisoning level.The measuring neutron amount will be subtracted by 1, the higher the more difficult to react.
The neutron type required for reaction.
The neutron type launched after reaction.
The neutron launch function, the number of neutron emission emitted by this fuel rod is determined by this
Description of the above functions, SAFE/Medium/Dangerous, represents the danger level of this fuel rod burst, and also represents the temperature and radiation speed that this stick can provide.
Increase the function of poisoning.All fuel rods are the same, incident volume*.0.5.
Reduce the function of poisoning.All the fuel rods are the same. The Chinese description is written wrong here. In fact, it is (income*incident volume)/50.Solution (x^2)/50> X*0.5's inequality can be seen that as long as the incidence is greater than 25, it will never be poisoned.
The core temperature increased by a neutron. If the emission volume is 100, this value is 1, and the core will increase by 100 degrees per T
The diffusion degree is the proportion of the core temperature passed to the surface temperature, and it is also a fixed 0.02.
The higher the difference between the core temperature and the shell temperature, the more passed to the shell temperature
The shell temperature will be melted when the melting point exceeds the melting point, and the frying pile directly
The higher the melting point, the less difficult to fry the pile
1.2 RBMK reactor fuel rod
Where to store the fuel rod, align the mouse to see some information.
Important thing
Fluxfast: the number of fast neutron incident
Fluxslow: Number of slow neutron sons
Heat: The temperature of the pillar, other components can also see that the information temperature exceeds 1500, which will melt the frying pile.
1.3 RBMK reactor graphite slower agent
Without GUI, the fast neutron passed will be turned into a slow neutron. Except for a few fission, the fuel rod that needs fast neutron is required.
1.4 RBMK reactor, tungsten carbide neutron reflector
Without GUI, the neutron original road that is launched on it reflects back.
1.5 RBMK reactor pile boron neutron absorber
Without GUI, absorb all neutron emitted on it, is usually used to avoid radiation leaks caused by neutron emission.
1.6 RBMK reactor control stick
The left is used for the control group of the console, and the right is used to control the value.This numerical representative means that through the proportion of neutrons that control the stick, 0%is quite comparable to the boron neutron absorbers.Specific to 1%value adjustment requires the console.
1.7 RBMK reaction heap slower fuel stick
It is a fuel stick that will turn the fast neutron that is launched on it. With this, you don't need to put a graphite slow agent next to it.
1.8 RBMK reaction stack slowly control stick
It is a control stick that will turn the fast neutron that is launched into it.
1.9 RBMK graphite reactor console
Its GUI explanation is more complicated, and it is not critical to this tutorial.See Encyclopedia https://www.mcmod.cn/item/453237.html
1.10 RBMK reactor steam pipeline
The most critical parts except the fuel rod are used for cooling fuel rods and generating steam.The left side is used to regulate the steam level generated, and the right side is the steam and water cache.
The four levels are
Steam: 100 degrees, steam and water ratio 100: 1
Hot steam: 300 degrees, ratio 10: 1
Super -thermal steam: 450 degrees, ratio 1: 1
Thick steam: 600 degrees, proportion 1:10
If you are committed to power generation, dense steam is the best.However, the cooling effect is the worst. If you are committed to radiation items, in order to keep the high -middle volume, the temperature does not fry the pile, please select the steam.
1.11 RBMK reactor steam exporter
The steam guide export of a block is convenient for the tube layout.
1.12 RBMK reactor channel
The speed of absorbing neutron proliferation is the speed of absorbing neutron.Special design without piles, slow and scary.
1.13 RBMK reactor glass coverage layer
Place in a place where there is a neutron, otherwise there will be radiation.Of course, you wear a set of high -radiation resistance, which is not covered.
Initial reactor construction
If you only centrifugs uranium, start playing RBMK, the only fuel stick that can be used in the early stage is only
Radium 226-m RBMK reactor neutral source
NU RBMK reactor uncomfortable uranium fuel rod
Uranus in Meu RBMK-235 Fuel Stick
HEU-235 RBMK reactor high concentrated uranium-235 fuel rod
The next-level uranium-233 requires irradiation channels to radiate 钍 232 production.Among them, the radium 226-镭 RBMK reactor neutron source has spontaneous combustion attributes, that is, it will launch neutron itself, without other fuel rods to provide neutron activation.The temperature produced in each launch is also very low and the melting point is low.You can't expect to be used for power generation, but when you are centrifugal uranium, there must be a lot of playing here.
NU and Meu are the number function, log (x)*x type."Very safe", the sub -quantity locks below 20.HEU-235 is a square root, but 235 is more difficult to get.So recommend the following method
Building materials total 4X radium 226-铍 RBMK reactor neutral 4X tungsten neutron reflector 5x radiation channel 16X slower agent (29x glass coverage board is not necessary)
Use four radium 226-镭 RBMK reactor neutral sources as a fuel rod, while the fuel rods are all on the four sides of the slower, three directions are connected to the radiation channel.Beckon.
In 5 radio channels, neutron flux is 80/40*4, and the fever is very low, and it does not even need steam cooling.The disadvantage is that there is no steam output, which is only suitable for rapid output in the early stage.
Primary processes reactor design
Congratulations to the initial entering the frying pile, the high -tech flux will be destroyed by a little carelessness.
Through the radiation channel, you can have been irradiated from uranium 233 to 235, ingots, 钚 238, 钚 239, 钚 240.But the next level 1 241 requires a horrible 800W flux.The output speed is very slow, and the high -tech general volume represents a very high temperature.
At this stage we can use a lot, but many of them are changes in value.Among them, the highest value is:
The number function: MOX RBMK reactor fuel rod LOG (x)*20, but its neutron calories are 1.5 degrees.
The square function HEU-233 RBMK reactor high concentrated uranium-233 fuel rod SQRT (x)*5.
One function HEP-239 RBMK reactor high concentration 钚 -239 fuel rod x*0.3 unit neutron calories are 1.5 degrees.
A neutron that can accept the fuel rod at most of the four direction, and the pursuit of speed needs to increase the amount of neutron emission of these four fuel rods.The same four fuel rods also receive up to three inputs. Without considering the linear function, the output of this fuel rod must be greater than 1/3 of the total input value, otherwise why do we not directly input this input to the radiation to the radiation of the radiation to the radiation.aisle.
Calculate the definition of log10 (x+1)*20 <(1/3) x. Its upper limit is only when the total input 126 is output 42. No matter how high it is, it is better to input .. So it is impossible to choose this thing.
The limit of Heu-233 is output 75. Next, design a radiation channel with 60*4 input.
Solve SQRT [x]*5 = 60, require the previous level input to 48*3. Solve the request to the second level input to 92/3 again. Use the radium neutron source to make input when reflected two times ..
First put it on the first level input
Reflect
Put on neutron source input and steam channel
Finally, according to your own choice to put on the pipeline and other components that prevent radiation. Put the 233 fuel rod in the first circle, and the outermost layer can be put in the neutron source.It takes only two seconds to deal with a 钍 232 ingot, which generates a thick steam speed of about 1500MB/s.
However, it takes 1600 seconds to deal with a 800W 个 241. It still takes nearly half an hour. Small batch production is okay. To further accelerate, it can only move to the process of further frying.
Advanced Ratal Formation Refuel Design
A large number of mathematics calculation warnings.This section can skip it, and the speed of 240 in the previous section is also possible, which is a little slower.Wait hard, and wait until the rare prime fuel rod can easily reach the speed of thousands of neutron. You don't have to worry about the frying pile.
There is a limit whether it is pairing or square, but why not use the dangerous linear function fuel rod HEP-239 RBMK reactor high concentration 钚 -239 fuel rod or higher numerical HEP-241 RBMK reactor high concentration 钚-241 fuel rod.
If you put on a three-sided reflection, the 239 fuel rod can reflect into the shooting end with a three-fold amount of input. Even if the radium 226-铍 RBMK reactor neutron source is incorporated, it will emit 60 neutrons to increase its temperature per second.90 degrees.
Before designing a dangerous design, you must first understand the temperature mechanism and mathematical computing.
First of all, the sub -quantity is related to the increase in the core temperature. Each neutron will increase according to the description of the fuel rod.Each calculation rises by 90 degrees.
Then the core temperature will spread at the speed of (core temperature-case temperature)/2 * diffusion coefficient to the surface temperature. The diffusion coefficient is 0.02 by default, so in the stable state, (core temperature-case temperature * 0.01) cannot exceed more than more than a secondThe heat dissipation, otherwise it will melt the frying pile.The surface temperature will be transmitted to the column body at a rate of (surface temperature-column temperature)/2*Dialheatprovision, and the default value of DialheatProvision is 0.2.Even if the surface temperature is 2700, the temperature of the pillar is 0, the maximum value that can be passed is 270 degrees. At the same time, the stable launch limit is determined.Floid speed cannot exceed 270*4.
The actual pillar temperature, even if it is perfectly cooled, it can be the same as the steam temperature during cooling.If you produce ultra -dense steam, at least 600 degrees, and the upper limit of the launch is 210.The steam is 260.
The cooling mechanism is the average heat in the pillars in the four directions, and the average value of each direction is (average temperature-target temperature)*dialcolumnheatflow.Dialcolumnheatflow's default value is also 0.2.The calculation example is that if the column is close to 1400 degrees nearly melted, the four weeks are 600 degrees of steam pipeline.The average temperature is (1400+600*4) /5=760, 760-600*.2=32 degrees.The steam channel becomes 632 degrees, and the temperature of the pillar has dropped by 1400-760*0.2 = 128 degrees.
After understanding the mechanism, return to the beginning of the example.239 fuel rod launch is 60, and the core temperature rises by 90 per second.In order to pass the heat, it must be passed to the surface, which requires the core temperature to be at least 9,000 degrees from the surface temperature.Then passed to the column, which requires 900 degrees.
If you cool through the cooling tower by 90 degrees.If the four weeks are dense steam channels, the solution (x+600*4)/5-600)*0.2*4 = 90, we can see that the maximum temperature of the column body is 1162.5.In order to pass 90 degrees to the pillar, the maximum temperature of the surface temperature was 1920 degrees.The core temperature is up to 10920 degrees.
Of course, this is the highest value of the limit theory. Due to the attenuation of fuel rods, natural cooling and other factors, it is usually impossible to achieve the theoretical value.
If you want to design a faster reactor, but the 239 fuel rod has reached 2700 degrees close to the melting point to produce a dense steam, up to a maximum of 128 degrees when it reaches a balance.quantity
To further improve, you can only abandon the thick steam output and use the steam to cool (what you said that the cooling tower is 1.12 here).If you use ordinary steam, the maximum cooling degree can be increased to 224, and a neutron capacity of 150 is launched.
To use three -sided reflex 239 fuel rods, the main problem is that if the constant function is not used, the neutron volume received by the 239 fuel rod will continue to increase the frying pile.The control stick is a two -way interception and cannot be used
Plan 1 is to use a slow fuel rod. Accepting the fast neutron of ordinary fuel rods will reduce the actual neutron weight by half, but the slowization will automatically quantify.
In the middle is the slow fuel stick steam cooled is 239 fuel rods, and the right side is the concentrated 239 fuel rod used in the activated neutron source
The maximum rate can reach 80, and a few more reflective columns on the right can reach 90.Over attenuation, the fuel rod needs to be replaced in time.
Plan 2 is a high concentrated 241 fuel rod. It uses two -sided reflection to achieve double increase.The disadvantage is that the cost is very expensive, and the advantage is that the structure is simple and the calculation is easy.If you want to launch 120, you only need to return 60 while receiving the reflection 60.
Basic framework, 241 fuel rod connection irradiation channel, 233 fuel rods maintain stability, neutron source and controller control the launch amount
The speed limit is 128, but it is recommended to not be explosive 120
The above two reactors will be attenuated over time, and the input needs to be increased with attenuation.At this time, you need to control the automatic control.
Advanced processes reactor design
In intermediate design, we can already calculate the stable state of the reactor to ensure that it is not fried.However, the initial state is calculated. As time changes will become larger, the fuel rod will gradually decrease efficiency, resulting in the failure of the parameters used in calculation.In order to achieve a reactor that is still stable over time, we can use an automatic control rod to allow it to continue to adjust with the attenuation of the fuel rod.
We need front knowledge before designing.Similarly, there are still a lot of mathematics calculations. If you do n’t have interest, please jump to the next section. The primary steam reactor design.
Formulating formula for fuel rods
The amount of fuel in the 1.12 fuel rod affects the amount of incident.The accurate formula is as follows of actual incident volume = incident volume*fuel surplus amount
Launch value = theoretical value*fuel rod special function (remaining value)
This is not the case for 1.7, but because this is the 1.12 tutorial for only 1.7 readers who do not know how to come in provide formulas, do not do further derivation. There are five forms in total.
The completely unchanged in * x // x is the fuel remaining value IN is the incoming value
In * (x + sin ([x -1]^2 * pi))
In * (x + (sin (x * pi) / 2))
in * (x + (sin (x * pi) / 3)
The default is 5, if the test value does not meet, please judge which one is
Back to the topic, due to the continuous decay of the incident value, we need to continue to increase the incident neutron over time.
Automatic control stick
GUI is like this, the four numbers on the left are respectively
When the temperature reaches the maximum value, how much should the control stick be adjusted to
When the temperature reaches the minimum value, how much should the control stick be adjusted to
Set the maximum temperature
Set the temperature minimum value
The following is preservation
On the right is the selection function. The function will determine how much should be adjusted when the temperature is set in the middle
The specific formula is as follows
Definition
The maximum temperature interval is to set the maximum temperature-set temperature minimum value
The temperature difference is the current temperature-minimum temperature
The control range is the maximum temperature control value-minimum temperature control value
Control value per degree. It is the maximum temperature interval /control block
Linear: The control value of the temperature difference * per degree of control + minimum control value. In fact, it is a linear function. If your temperature reaches 50%, the control value will reach 50%.E.G. Set up maximum control 0, minimum 100. The maximum temperature is 100, minimum 0. Each degree is 1%. When the temperature reaches 50 degrees, the control rod becomes 50%.
Second, the square (temperature difference/maximum temperature interval)*control range+ minimum control value.The function graphics is like the game, the temperature control value is small, and the back is large.
The third is the second one.Specific mathematical formula (current temperature-maximum temperature)/(minimum temperature-maximum temperature)*(minimum control value-maximum control)+minimum control value
Which function to choose depends on the function that needs to be controlled.
Control rod rising speed
The control stick is not instantaneous, it takes a certain time.Therefore, if the automatic stack is close to the edge of the frying, the control value of each degree is too large, which will cause the lifting too slowly and fry the pile before falling to the right position.
The specific speed is 0.277/t, and it takes 18 seconds to 5.5/s from 0 to 100
Example of fuel stick control
Next, the reactor with a reactor with a high concentration of 241+ radium in the radium radium is used as an example to demonstrate how to control a reactor.
First of all, the left is the sore at the left, and the right side is 241.
First of all, we determine a goal, for example, let 239 keep the launch of 20 neutron weight.
Since we use the temperature as the control volume, we first need to calculate the incidence when the volume of 20 neutron volume is launched.
Calculate the corresponding temperature, but the control rod cannot turn its own temperature into 600 after each calculation is over, and the simple formula of the steam channel cannot be used.Either you must calculate the recursive formula of the two variables, or go to the game to measure it.The result here is 630.
After setting these two parameters, the minimum temperature control and minimum temperature of the remaining two parameters.The minimum temperature control determines the attenuation limit of this reactor, because even if it is pulled to 100%, the attenuation cannot be maintained above 50 when the attenuation reaches 0.85.Solution X = 0.85 (20+0.8X), x is 53, and the attenuation of the neutron source has not been considered yet.
The minimum temperature is mainly to determine the control ratio.If a linear function is selected, the control ratio of 50 (1/maximum temperature interval)*50 every time the decrease is selected. If you choose 580, each decrease will increase by 1%.
In addition, it is also determined that the acceptable attenuation efficiency is also determined, because when the 630 declines, the 1%control rod will be improved. If 1%can rise at a time, it can be maintained at 630.If too much attenuation, a new balance will be achieved at 629.If you want to keep as much as possible above 630, the temperature range should be smaller.
For example, set the minimum temperature to 629, so that it will jump repeatedly. As soon as 630 is lower, it will rise to increase the temperature.However, it is clear that due to the problem of heat transfer rate, the reactor that controls the upper limit of the temperature will explode directly.In addition, this is also very unstable, and the range of heat fluctuations is large.
Fuel stick recycling
When a fuel rod is consumed more than 10%, it can be recovered, and the corresponding fuel core block can be obtained.The surface temperature must be recovered at 20 degrees, which is completely cool.You can put it in the fuel pool to cool down, or you can directly put a fuel stick that is not running to cool it. Of course, it is not spontaneous.
Attenuation of fuel rods
The consumption of the fuel rod is a NBT label. Check the fuel rod with a tool to view the NBT. You will find a field called Yield. The full fuel rod value is 100000000.EssenceIf you use a fuel stick with poor numerical values, you may not be attenuated in one day.
When to recover the fuel stick
Relying on its formula, the linear fuel rod is attenuated by 15%, which is basically half efficiency left.The square shadow sound is relatively small, but it should not be attenuated to more than 50%from the efficiency of game time efficiency.
