*Note 1:* if looping the high pressure steam back through the exchanger as I did, remember to take that into account when calculating how many tubes you need! *Note 2:* You can now copy the tube side configurations along a line by sneak-placing - should save a lot of time!

[@huba9930]

the tubes seem to be very difficult to set up (even with shift) and when it doesn't work, it's hard to troubleshoot. how about coloring the tubes? then they can auto connect within a color but don't mix. and to make it very easy, marking the output (vent or last tube) so it "request" fluids would help too.

[@abduahmed6639]

Can I take the steam and use it to generate electricity with hbm steam turbines?

[@Schplatnel]

Wow, just wow. This is so, so awesome. I’m making one of these inside my server with my friends right now, this is probably the closest to thermodynamic accuracy that Minecraft will ever get. I’m a mechanical engineering student and I’m taking heat transfer right now after thermodynamics a year ago so this is all so cool to me. I feel like I’m going to have to start drawing T-s diagrams, lol. I’m building a big room where I have all of the processing machines to make the FLiBe mixtures for fuels and NaK mixtures for coolants. Then I’m going to make a big room with a balcony that overlooks the reactor, heat exchanger, and turbine. It’s gonna be so neat when it’s done! Also, are you a real life engineer? I feel like only an engineer would make a Minecraft mod this accurate. One last thing: Excellent choice in music. Money for Nothing by Dire Straits is my favorite song of all time. I love playing the 8 bit version on the jukebox when I’m building reactors, haha.

[@NuclearCraftMod]

Thanks verey much! You are one of a reasonably small group to really go crazy with the MSR setup, so good luck! Although it gets closer than most, there are still inaccuracies - the physics of the heat transfer make very little sense realistically, for example. The new versions of NC will fix that :) I am studying physics at uni, but NC developed many years ago into more of a nuclear and thermal engineering mod than originally planned :P

[@proxy1035]

this makes everything so much more complex and i love it! so you now can get a almost completely closed circle!

[@NuclearCraftMod]

Yep, just the condenser to go :)

[@beherith2874]

This is literally so cool to actually think about what ur doing and engineering the whole system bit by bit. So much more innovative than to judt put down a draconic reactor. Also this molten salt stuff is so awsome. Thx for your work, you da best.

[@NuclearCraftMod]

Thanks again! Just about to get an update out which completes the Rankine cycle. Will record a video going through the whole thing ;)

He may have knowledge, but he is no physicist.

[@aquasama588]

We all have knowledge of physics like "Fg= Gm1 m2/R² " or "E = mc²" and it's just a minecraft mod, never think that everything that is in minecraft is the same as real life. It's just a game...

[@Shark_A_Tack]

The new molten salt stuff looks like it'll be fun to play around with. I have one suggestion however, a copy tool for copying the settings from one heat exchanger tube to another or for the reactor cells would be really nice because having to click on the individual blocks so many times seems kinda inconvenient.

[@NuclearCraftMod]

A couple others in the Discord server have asked for the same - on the to do list!

[@polyjohn3425]

It could be as simple as shift+right-clicking a tube onto an existing tube places the new tube with the same settings as the one already placed. That would greatly reduce the tedium of running straight lines, at least, even if it doesn't exactly help going around corners and such.

[@NuclearCraftMod]

@@polyjohn3425 Your suggestion turned out to be the slickest one - added in the latest version :)

[@sbowen574]

I'm really loving this mod and I had a triple solid fuel reactor setup in Modern Skyblock 3 that was really fun to automate! I'm playing through Enigmatica 2 Expert Mode right now and I'm really looking forward to trying to make this my main power source!

[@NuclearCraftMod]

Cheers! Good luck with your next build :)

[@sbowen574]

I'm going to try my best to automate more that just Fusion and Fission, those salt reactors are making me just scratch my head at the moment

[@falizure]

could you use the same exchanger frame for both high pressure and normal steam, in other words having your rows of hot coolant and water in half of the exchanger, and then feed the high pressure steam and water in the other half to cool it down to normal steam? in theory that would save in casings by removing a redundant wall and extra piping since your just going over to another section on the same wall rather then around to a separate multiblock. The problem i see with that is in dont think the interface is smart enough to account for cooling multiple types of fluid BUT if it did work in theory you could do some sort of double layered system where you wrap your hot coolant in water, and then wrap the water lines in your high pressure steam lines, that is assuming you had enough water flow to take all the heat from the coolant and high pressure.

[@NuclearCraftMod]

Yep, that's perfectly valid :) All that is needed for the heat exchange to occur is for a cold -> hot recipe to flow past a hot -> cold recipe :)

[@JYPark1101]

Would it be possible to have transparent tubes? It would be awesome to see the thermal exchange in action

[@JYPark1101]

Now I think about it, it might not be possible to design such block that looks good

[@AlexJones-qf7rw]

@@JYPark1101Could possibly be made with some sort of gradient. Like going from blue (water) to white (steam). The heated stuff would be a little more complicated though.

[@fueege374]

Чудно!

[@sharkyk0223]

I'm using this version of nuclearcraft in the modpack I'm using and my heatexchangers say the tube activity is only 80% and sometimes drops even lower why is that? is my reactor too cold? or is the design of my heatexchanger

[@sharkyk0223]

nevermind I think I get it now these MSR take a lot of time to balance out so glad I went into creative saving so much time, good mod

[@JohnDoe-kf3rd]

These multiblocks are still broken, right?

[@MakarovFox]

i like this reactor, that the coolant is a fluid that you need to pomp in the reactor like real life something that would be interesting would be a reactor that needs liquid coolant but uses solid fuel and used this heat exchanger to produce steam and maybe a simple reactor that use solid fuel and water for coolant so the water heat up and exit the reactor like steam and the steam go to the turbine then it condenses and returns to the reactor in a close system and you can see in the reactor the water and the steam if you mess up the reactor break an steam exit out of control and meltdown like chernobyl

[@NuclearCraftMod]

I'm not sure about mixing solid/liquid fuel/coolant yet, but if the maths works out nicely in a way that would encourage different reactor styles, we could definitely try it!

[@MakarovFox]

@@NuclearCraftMod nice thank you, your mod is really cool yesterday all day whit the mod testing things

[@lorddeathofmurdermountain76]

I have a question can you add like a ingame guide to how to build these reactors

[@NuclearCraftMod]

I will at some point for the overhaul version, yes :)

[@zecorezecron]

Ok, so I've watched this a few times and I'm a little fuzzy on something. When you are explaining the heat transfer rates between the cooling tubes, it seems like the total amount of heat is not conserved. As in the water is gaining 400 heat per tick while the coolant is losing 900 heat per tick. Is this correct or am I simply misunderstanding things? Usually I'd just over design this sort of thing, but my reactors tend to be 9X9X9 monstrosities so that's not really feasible.

[@NuclearCraftMod]

You are correct, yes - this is one of the major things that will be changed/fixed in the overhaul :)

[@zecorezecron]

@@NuclearCraftMod Thanks dude, you're amazing.

[@NuclearCraftMod]

@@zecorezecron No worries!

[@bentcheesee]

I am so confused I just want to play SkyFactory 4, yet I can't wrap by brain around this

[@NuclearCraftMod]

If I remember correctly, SF4 doesn't have any quests for the later multiblocks, so hopefully you were alright :P

[@Exo594-b5v]

Does it ONLY work with a counter-flow heat-exchanging design? Would there be any advantage to a zig-zagging entaglement of tubes that increases shared surface area, vs. having several individual tubes surrounding one other?

[@NuclearCraftMod]

Exo 594 As long as the flow is not *parallel*, then it will work, so you can have any sort of crazy design with the tube flows perpendicular or opposite ;)

[@ryuguy032197]

first off you can still have counter-flow while having a zig-zag pattern, and another way I imagine it is that if you think of a double helix(you know, what DNA is structured as) and the hot fluid flows one way while the cool one flows opposite. it will increase the surface area and amount of heat exchangers used.

[@Exo594-b5v]

Yeah, I was thinking something similar. I'll be interested to see something like a "twin spiral" works compared to a checkerboard or layers of snakes.

[@NuclearCraftMod]

Very true - also keep in mind that tubes can be 'interlocked' by playing with the flow direction of the product fluid as the long as the input fluid is spread in the right direction :)

[@RF_N]

I feel like this mod is the better ic2 (maybe..)

[@ryuguy032197]

will you add support/ore dictionary for IndustrialCraft 2's high-pressure steam, and steam turbine.......... (IC2 uses the same turbine for high-pressure steam and regular steam)

[@NuclearCraftMod]

Ryan Schultz I might be able to, yes. There is no ‘ore dictionary’ for fluids, so either I’ll have to add the recipes or the IC2 devs could.

[@AlexJones-qf7rw]

@@NuclearCraftMod Correct me if I'm wrong but didn't Forge recently add "Forge fluids"? I remember that I played some time and was looking for a buckets of some fluid. Turned out it had been sorted as a "Forge liquid bucket".

[@shamux4043]

Are there any plans to make solid-fuel reactors produce steam for turbines?

[@NuclearCraftMod]

Check out the recent overhaul videos :)

[@Keineahnung4015]

Hello, I hope somebody is going to help me. I have tried building an heat exchanger just like you did in the video, but it is not working. It is consuming water and hot coolant, but it is not outputting anything. I am using NuclearCraft-2.18o-1.12.2 in Mc. Ethernal

[@NuclearCraftMod]

Will just ask here for completeness - did you solve the problem after the discussion in the Discord server?

[@Keineahnung4015]

@@NuclearCraftMod Yes, it did, I didn't power the heat exchanger with a redstone signal.

[@AlexJones-qf7rw]

The amount of maths you need to do tho... I think I need to rewatch it a few times to understand. Math was never my strong point. You got a wiki or something with the values? Cos it's not the easiest to follow along in a video. Still I'd think it's nice how realistic you're trying to be here and you do seem to enjoy it a lot. I'm a little concerned about the amount of IDs the mod uses though. I experienced first hand twice how the IDs exceeded Minecraft's hardcoded limit of 4096 IDs when making my own packs. Sure there are mods to alleviate that and 1.13 is redoing all IDs but it's just something I've noticed when trying to recreate your test modpack (cos I wanna get into all this new stuff.) Not sure how much you can do on your side though.

[@NuclearCraftMod]

I've recently set up an MSR and Heat Exchanger calculator that you should be able to make a copy of and use to help with the calculations :) docs.google.com/spreadsheets/d/1dMKsUrZST3iK1dgOlLnxShaFYcidx_s9zHVtMeRf1lM docs.google.com/spreadsheets/d/1ZV5va57mvOl86M66vGs72CE9XW2p4jG4cwHD9qEdLqM As for IDs, I could technically be a little more sparing with the multi-block parts, but really not by that much. For example, blocks that have different states, make up parts of different types of multi-blocks or even must be places in different places in the structure can not share IDs.

[@KWash-xu9nh]

Does the heat exchanger work with a solid fuel fission reactor?

[@NuclearCraftMod]

No - right now, the solid-fuel reactor produces energy directly, and in the future it will produce steam for use in turbines. The only currently planned sources of hot coolant for heat exchanging are the MSR and fusion reactors.
