You know you can always ... not use it (and probably disable it in config)
it will also be much much more expensive than a RC tank so probably still best to use one of them.

on the topic of nuclear waste: since IC2 reactors appear to be fast reactors (ie no neutron moderator) they would produce a much much smaller amount of waste than the inefficient reactors used in most RL plants. What would happen though is the reactor chamber and stuff near the reactor would get radioactive over time (due to neutron radiation).
Maybe have it so that anything that is near a nuclear reactor for too long becomes radioactive and results in radiation poisoning if approached without proper protection. Also have the blocks maintain the radioactivity if moved from the reactor, but slowly lose it over time. Also have some block type that absorbs the neutrons (thereby becoming very radioactive) and stops blocks on the other side of them from getting irradiated. This way it would make more sense to build a containment vessel around your reactor, not for explosion reasons (Nuclear reactors cannot go boom like a nuke, it is not possible for them to get to the supercritical mass needed), but for blocking the neutron radiation.
Have nukes irradiate any blocks near the blast, but have this irradiation drop over time as well.
http://en.wikipedia.org/wiki/Fast_reactor
Note that on the above page it mentions that this type of reactor can use most of the contents of the current nuclear waste, by transmuting the waste into more fuel, just like the IC2 breeder reactors.
also note under the disadvantages it states that control is done via neutron reflectors, rather similar to the ic2 ones

I see, that you are actively working on your mod, thats great.
Another suggestion is stupidly simple:
making "oil refining" a more real process.
Oil > fuel is funny, because roughly 2\3 of our surrounding are based on oil refinement byproducts. USE THIS TO YOUR ADVANTAGE!!
I say, best would be to make some big multiblock structure (towerlike) which will do processing on different tempretures. I can expand this idea, if you wish.i agree with this, having a proper petroleum refinery would be great.
As for the reason i use nuclear reactor in steam mode:
if only running at about 200-400EU/t it is more energy/fuel than normal. it doesn't work too well at more than that due to problems getting enough steam pipes connected (i use valve pipes industrial pipes)
also, it makes the reactor more expensive, bigger, more impressive and more realistic -
For fear of highjacking my own thread, the steam functionality of Railcraft looks sick! Definitely can't wait to go play with steam turbines and the likes - having a basement full of boilers will look awesome.
I only operate my nuclear reactors in steam mode now

Greg, would you mind adding an electric bucket filler, because all the bucket filler mods i can find are 1.2.5.
thermal expansion would be your friend there

@the comment on degenerate matter armour
Electron degenerate matter is not stable at low pressure (unless the temperature is approximately 0K), so is impossible to make armour out of as whatever you are using to keep it degenerate would provide much much better armour than the degenerate matter itself.
@the nuclear fuel topics:
The only ore that would make sense to add would be thorium ore, more common than uranium (by factor of 3 or so). this would be op, so my suggestion would be to nerf uranium ore to 1/4 of the current rareness, then make thorium ore 3x more common. then require uranium dust to be centrifuged (or even mixed with fluorine capsules to make uranium fluoride, then centrifuged) to get the uranium used in nuclear fuel. Then have the re-enriched cells be centrifugable to get plutonium and thorium cells.
This would be a much more realistic way to get the plutonium for the nuke, as well as will mimic the extremely long process needed to enrich uranium. It will also nerf the nuclear reactor a small amount, as thorium cells would be the more common one, and they make less power (same energy).
Then, if you do ever implement my stuff from water idea, you can have it not give any thorium and just give uranium (uranium is much much more abundant in seawater than thorium is)
edit: about the americium, it has a much lower half life (longest isotope is 7370 years) so does not occur naturally in any usable quantities. (neptunium has half life of 150,000 years, so not found in any large amounts, but some is generated during nuclear processes in uranium ore so is a bit more abundant) uranium has a half life in the range of 500M-4.5B years depending on the isotope, so is still around in large amounts.

Gee all this talk about having a star use iron as fuel... lol you know what neutron stars are made out of right? Iron... very, very highly condensed iron. It sometimes is what is left over after a super giant star goes super nova and blows itself up in a violent explosion. Of course there are only two results of a super nova happening, the core which has become so dense can't support the material around it so it either implodes and becomes a blackhole or it blows off all it's layers leaving behind it's core which becomes the neutron star.
neutron stars are not made of iron, they are made of neutron degenerate matter, ie a nucleus of Z = 0 and A = 10^n where n is some large number. Iron cannot exist in nuclear degenerate matter, as electrons cannot be confined in such a small volume along with protons, it is energetically favorable for them to undergo electron capture in those conditions, resulting in the formation of neutrons and neutrinos.
edit: If you do attempt to stick a bare iron nucleus onto nuclear degenerate matter, there would be enough gravitational potential energy to form enough electron/positron pairs that the electrons would combine with the protons, then the positrons would later annihilate any electrons that got attracted to the slightly positively charged neutron star.
the black hole or neutron star are formed almost entirely from the core, stars that result in black holes also blow off the outer layers.
Edit:
Back on the topic of the polywell fusion reactor:
The pipe things would be for water/steam and for fuel intake/waste output.

since i can't get to sleep, will respond to these posts
If my own meager knowledge of astronomy is anything compared to what's being talked about right now, then, if I recall correctly, smaller stars are essentially guaranteed to form white dwarfs at their 'death,' and the 'middle class' stars become neutron stars, and the 'super massive stars' are the ones that have so much mass behind them at their death that they form black holes. Again, my knowledge is meager, old and has been too deep in the 'archives' for so long, I think it eroded a bit, so I could be wrong.
Thutmose: I think what Crafter meant by "ripping spacetime" is that the massive gravity of the black hole causes a massive time dilation effect due to (I believe) the black hole sucking in light, meaning that it's harder for distant observers to make accurate guess based on time.... Now that I think about it, the phrase should be closer to "stretching spacetime to near breaking" which is so close to ripping, that people just go straight to "ripping."
some very very small stars do not have enough mass to result in the electron degenerate matter that composes the white dwarf, so just turn into brown dwarfs instead, otherwise your generalization is quite good.
The gravitational field near a black hole does necessarily cause any large gradients in spacetime. the larger (physically) the event horizon, the lower the resultant stresses, so it actually has less tidal effects than a small one.
The definition of a spherical event horizon (aka the "surface" of a black hole) is the surface of radius r, such that r = 2*G*M/(c^2), where G is the universal gravitational constant, M is the mass of the black hole, and c is the speed of light. this means that the radius of the black hole is proportional to the mass, and a sufficiently large one would not really affect space time (in terms of a "steep stress") that much.
The time dilation effect is just a result of the apparent acceleration as the object approaches the event horizon, and has nothing to do with the black hole absorbing light, just to do with the strength of the gravitational field.
On the topic of Artificial Stars
why do you want such a horribly inefficient source of energy?
The volumetric power density of core of the sun is approximately the same as a lizard or compost heap. keeping a pen of cows next to a RP2 thermopile, next to a block of water would be a much better power supply than a star of comparable size. If you take the whole volume of the star, rather than just the core (which is about 1/4 of the radius, or 1/64 of the volume), you would now get much more power per volume from sticking a thermocouple to a mildly radioactive object than out of your star.
A few references: http://en.wikipedia.org/wiki/Solar_core#Energy_production
TL:DR
Stars are very very bad sources of energy if you have to build a new one, practically anything we can make would do the job better.note: our methods of producing fusion result in many many orders of magnitude higher power densities than stars can ever hope to achieve, mainly due to the fact that we can choose to introduce only a specific set of isotopes to fuse, and we can operate at much much higher temperatures, and comparable pressures (in the case of the polywell design the effective pressure at the center is very very high, despite being in a vacuum chamber)
-
In then which creates a white dwarf. And while we are on astronomy i might as well say if that is a duo sun it will suck all of its energy and... Well it will explode with the most powerful super nova. But the larger stars collaps when the atoms in the core are put under pressure until it rips spacetime creating a blackhole, and when it feeds on the surrounding star spitting out gammaray bursts(?) this is all from memory, i may not be correct.
The collapse doesn't "rip" spacetime, all a black hole is, is a gravity well which light cannot escape. current physics does not actually explain what happens once inside the event horizon, so anything beyond there is merely speculation.
The white dwarf is what is sucking matter off the companion star, not the other way around. the reason why the dwarf explodes is that at approximately 1.38 solar masses it reignites with carbon fusion at the core, and the large amount of energy produced by this causes the supernova.
Some larger stars produce neutron stars instead of black holes, the source of gamma ray bursts is currently uncertain, but it is probably either neutron stars colliding or large amounts of matter falling into a black hole (due to conservation of momentum related reasons when stuff falls into a black hole, right before it gets to the event horizon, sometimes large amount of energy is shot away from the black hole.)
-
One question, if you try to fuse iron in a reactor would it explode like a dying star?
no, it would just consume more energy than you gain.
Edit: the only reason a star explodes is that the core no longer generates the energy needed to prevent gravitational collapse, and the resulting collapse generates shockwaves that blow off the outer layers. This means that the explosion only occurs due to the use of gravitational confinement. Any other confinement method is based on external factors, and will not result in an explosion if you start losing energy rather than generating it.
Also, some stars "explode" before they even get as far up as iron, as they do not have hot enough cores to fuse past carbon, which will produce very large amounts of energy, but needs a fairly high pressure/temp to start the fusion.
Edit 2:
For the fusion reactor you might consider doing one of these instead: http://en.wikipedia.org/wiki/Polywell
For this you would want to have some sorta spherical chamber with coils around it, being minecraft, in a cube, with 6 rings, or even 14 rings (6 as faces of a cube, 8 as the corners, so a truncated cube) With nothing in the center (have the rest of the cube filled with vacuum chamber block)
hmm seems someone beat me to that idea...
You then get steam out of pumping water into the walls, the walls can also produce tritium, though this would do D-D fusion just fine.Last edit before i go to sleep:
The main advantage to the polywell design in reference to minecraft is that realistically it can be much much smaller than the tokamak. a realistic tokamak for fusion power generation is huge (see the image posted by crafter, and note the size of the human reference), in comparison, a polywell would only need to be a couple meters in radius to be viable, so could realistically be built 4 blocks tall or so, compared to the 10 or 20 blocks minimum for a realistic tokamak.
-
I'm surprised about all this fusion talk... but something came to mind then. Wouldn't certain elements when combined produce more energy than certain elements?
yes, depending on which reaction you use you get a different yield, but also different containment requirements, the relevant wiki topic covers some of the relevant details: http://en.wikipedia.org/wiki/Fusion_power
You will see that the D-T reaction is not the highest energy gain (actually quite low), but is the easiest to get going. On contrast, the D-He and H-Be reactions produce less neutron radiation, much more energy, but are also much harder to contain, so may not be feasible in a tokamak design.
Pinkishu you could always do what i currently do for the macerators: have multiple of them and have each only take a certain subset of ore, that will help solve the problem until greg implements a way to detect if something is full.
-
Reading the "possible to do list" again... What kind of protection will the nanite and force field suit give you? (if it ever gets implemented) and will they be stronger than quantom
most sensible nanite suit would be some sorta utility fog like system (http://en.wikipedia.org/wiki/Utility_fog) where a cloud of it surrounds you and detects/stops anything that much harm you. The "recharge" cost would then correspond to the energy needed to allow whatever is controlling the fog to rebuild more foglets whenever they get damaged by whatever is trying to kill you.
If you do use some sorta nano fog like system for armour, it would technically only require 1 worn piece, the control computer. This would then allow for the ability to wear other things like bat packs, and still get the full use of the armour. This would also make sense to require a computercube or so in the recipe, as it would take quite a powerful computer to control the huge number of foglets needed to make up the armour.

When i think of a multiblock fusion reactor,i think of something like this
This is initially a ring with coils surrounding it and a magnet in the center(?) I was thinking about you would build something like this structure and use pipes to pump in tritium and deuterium, then flip a lever to activate the super magnet and start fusing the two elements.
the donut shaped chamber is where the plasma is contained. the stuff (i think the green parts) around it is the magnets for containing/heating it.
The magnets surround the vacuum chamber, and contain the plasma to the center of the chamber (keeps it in a ring not touching walls) The magnets also allow energy to be put into the plasma to heat it to the temp needed to initiate fusion.
Once fusion starts the radiation produced (mostly gamma and neutron) hits the walls of the chamber and makes it get hot. The neutrons also convert lithium into tritium in the walls. Water is passed through the hot walls to get the heat out to use to make electricity.
There is also a system to extract the helium produced, as it would otherwise poison the reaction.
-
Thank you, that will help.
Edit: Multiblock fusion reactor?
If you do make the fusion reactor multiblock:
Assuming it is a type of tokamak reactor (indicated by the need for an advanced computer to control it as well as the shape of the fusion coils) then the heat should be produced in the walls of the coil, then transferred to whatever turns it into electricity.
This would mean that maybe you could make it so that the fusion reactor could output steam instead of EU (still needs the input to start it, but to a different part). Since the liquid api was moved to forge, you could probably add your own high capacity steam pipes, which go into some turbines (very much like the railcraft ones). This would then allow for a natural progression from fission to fusion reactors, as both would require the same steam + turbine setup, but the fusion one will have more room to extract pipes from (much larger structure) so will be able to run many many more turbines than the fission version.
This would ofc stop it from having to output to a supercondensator, though that might be solvable via implementing an advanced turbine that outputs that high, but needs absurdly large amounts of steam to run.
-
First of all, there wouldn't be "a chance" as soon as it fuses iron it explodes. Iron is the death element of a star.
Implodes, not explodes, iron results in the core imploding (the resultant shock waves outwards which result from instabilities during the core collapse blow off the outer layers of the star in the form of the supernova/planetary nebula formation)
This implosion occurs as iron fusion consumes energy, which would cool the star if it occured, so the core contracts (due to both the contracting effect of a cooling gas, as well as the lower thermal pressure to oppose gravity). Similar implosions occur in stars that are too small to fuse lighter elements, just without the accelerated cooling (which would only last for a very very short time, if it happens at all).

pick your poison of technical information :p
hmmm planning planning... geez... trying to figure out a good reactor design with the new cells is difficult... almost always blow up on me in simulation... designs from the nuclear engineering section seems obsolete with these new cells in the mix lol...
though if you also use railcraft you notice that the maximum possible output of the reactor is dropped (limited by the number of steam pipes, even will the valve pipes mod that has the industrial pipes), though it is much easier to get a stable, highly effecient reactor that will suffice while you build the components for the fusion reactor. -
NEI won't bring up the uses for the heat rings. I would expect them to go in the fusion reactor. Speaking of the reactor, what exactly do the coils do? Do the elements fuse in them, or is it where the heat comes from?
Simplest answer to the question about the fusion coils:
They contain the 100MK+ plasma to prevent it from touching the walls of the chamber and they provide a method to heat the plasma to that temperature without wasting too much energy in loss to other media.

Forgive me if I'm repeating something someone's already said but reading through 20 + pages of a thread isn't a fun prospect...
Got a industrial grinder set up, grinding ores down fine an all until they stacks get halfway done and the process grinds to a halt and stutters. It takes in another dust and water cell and the progress bar then just flickers near the beginning and doesn't move, it keeps flickering like it wants to move but doesn't. basically I lose 1 dust each/ore and a water cell and am forced to break the block to reset it. It's rather annoying seeing how a lot of the stuff to make more advanced stuff is made inside this machine. It seems to happen when the player closes the GUI and reopens it to check the progress.Now I might be a bit behind and it could have been fixed already I just want confirmation since I just updated it and was wondering if something is amiss.
check your power going to it, if it does not get the full 128EU/t it will act like your description. what might be happening is you are draining your storage (why it works fine at first), and your production is not keeping up (so it stops working after storage is empty)

Why would you want to use a blast furnace to melt aluminium? based on its physical and chemical properties using an induction furnace would be a much better idea.
relevant physical properties: Low melting point (<1000K), fairly Conductive.
relevant chemical properties: Highly reactive, so induction furnace is easier to arrange the needed inert atmosphere.Related suggestion: Maybe have another easy to obtain inert gas (say argon extracted from air) to use in the second slot of the blast furnace as an atmosphere for smelting of reactive metals into bars (aluminium being one of the more common very reactive metals)
Suggestion on how to obtain said argon: Compress/chill air cells to get liquid air cells then put the air cells into a fractional distiller to get nitrogen, oxygen and argon cells (or just extract it). (you might even be able to assume that the minecraft atmosphere has more argon than earth, so get more argon than the normal 1%)
Edit: as it currently is the aluminium seems to take a bit too long to smelt, given it's melting point it should smelt much faster than the other metals in the furnace

I would be interested to see some higher power condensors running off diamond dust or ender dust
Redstone > Lapis > Ender / Diamond
Not sure if ender or diamond should be higher as both can be moderatly difficult or easy to obtain, probably ender > diamond due to the ease of endereyes late game.But why waste the enderpearl dust on that when it should be used to make neutron reflectors for use in large scale excavation projects! (aka nuclear excavation)
