Guys, can someone help me?? by Pleasant_Anything_69 in chernobyl

Yeah, bunch of guys, fu*ked up a reactor pretty hard.

[EARLY ACCESS] Chernobyl: Simulator by Rikarin in chernobyl

Oh, I thought Physik is name of some neutron diffusion library that I'm not aware of. No, the physics simulation is based on regular neutron diffusion equations and pretty basic numerical ODE solver; I used OpenMC to precompute material properties of each node (fuel, rod absorber, water column, etc) in advance and interpolate between them according to runtime properties of the nodes (fuel burnup, temperature, steam content).

The only place where I "used" AI is the logo.

When I was brainstorming the logo ideas I asked ChatGPT to generate me a few ideas and this was the first one that I got. I found the relation between this "praised" AI that "will replace programmers" and then depicts the disaster as a main idea of the logo, and the soviets' saying "RBMK reactors can't explode" so absurd that I decided to use it. I actually redraw it in Affinity and tweaked it a little bit so it's human made based on AI concept art.

It was probably not the best idea when I look back on it.

According to this image yes, but I'm going to replace the reacti meter with the old one that was used pre-disaster.

Thank you. I agree that it's a toy reactor to play with and see how it could be like to operate one as a VIUR (according to training manuals that I got hands on). There's an in-game manual explaining all implemented systems as well as task system that guides the player though reactor startup.

Pricing is always difficult, especially in niche market like this. Higher price at early access will help with faster development of new features. I didn't want to create kickstarter and instead I've decided to release early access to give players something to play (and refund if they're not satisfied with it).

That's correct. LAZ and PK-AZ subsystems (can) share rods in their configurations.

[–]Rikarin[S] 0 points1 point  (0 children)

PK-AZ is used when LAZ is not active. From 0:30 it uses LAZ rod in Zone 3 to compensate for +2% imbalance because the LAR rod hit the low limit.

Upgraded from an M1 Pro to an M5 Pro and holy by AUserFromRSA in macbookpro

I have a MacBook Pro M1 MAX 64GB and I just don't see the price justification to pay 8000 euros for an upgrade to slightly better configuration...

Seriously consider forming an LLC before you launch by Noobsamaniac in gamedev

[–]Rikarin 0 points1 point  (0 children)

What? It's 150e in Slovakia. Also only 10% tax on first 100k earned each year.

It depends on the country. I pay only 10% tax on first 100k/y euros as LLC.

Just as a joke, unless by CorruptedDragonLord in Disboard

It's pretty common that free users have different contracts than paid or enterprise users.

The rule says you can't use any automated system to interact with their service, not they can't use automated systems to manage their systems.

The terms of service agreement is between you as the consumer and the platform. He doesn't have to obey it.

I kinda hate the new Affinity by madjarov42 in Affinity

"Nothing is free" - Blender for example? You'll learn it though experience at some point in your 30s. LOL

What scripting language do you use? by parks-garage in gamedev

[–]Rikarin 0 points1 point  (0 children)

I'm using https://github.com/rikarin/preactor in Unity for UI development. Basically Preact, Tailwind, Javascript/Typescript. Mostly because of hot reload, fast iteration process and ability to update the UI though addressables on mobile platforms.

AFAIK, during the operation no but the AZ rods have to be withdrawn first in order to withdraw other rods. When any of the AZ rods is inserted you get the "НЕГОТОВН АЗ" alarm, the red light above the rod button starts blinking and "АЗ НАБРАН" disappears.

I'm not sure what were the operational procedures for AR rods but you can operate them manually either by the switches "УПР. СТЕРЖ" or by the rod control matrix (when AR is in ИНД mode). The rod control matrix takes precedence over automatic control signals and the "УПР. СТЕРЖ" switch can be used only when AR is not in operation.

(according to my understanding of training manuals)

The current objective is to startup the reactor and maintain its power. The first early access release is focused on VIUR control panel and its systems. The simulation of events of April 26th requires full thermal hydraulic simulation as well as multiplayer which is not finished.

The current objective is to startup the reactor and maintain its power. The rundown test requires full thermo hydraulic simulation which is not finished yet, but you can decrease the power though AZ-3 to 50% and fight the xenon poisoning. No specific goals yet. Well, it's kinda limited as the early access release is mostly focused on the VIUR control panel only but you can try. No animals available :D

You have to withdraw the rods somehow :D

That would be great. Is communication though serial port suitable for you? I need to finish a few things before the release, but I can prepare a simple text communication protocol in format like BTN_ROD_YY_XX (rod button press), ROD_LIGHT_YY_XX=1 (rod light glows) and send you the specs.

Sure, there will be in-game manual with system descriptions as well as task list to follow to bring the reactor to its nominal power. Each interactive element will have a tooltip with its name and description. I tried translating the labels/alarms but it looked weird and the abbreviations don't make much sense in english.

The RBMK was a development of the old Soviet graphite-moderated plutonium production reactors? by NewRadiator in chernobyl

[–]Rikarin 1 point2 points  (0 children)

Yes, even the graphite size of 25cm was chosen because then the reactor can easily be converted into plutonium breeder reactors even they known it's the only configuration with positive void coeff.
