I was thinking, in most of the cience fiction movies (also in real live), a big throuble presents into a ship when the reactors are damaged, causing even somekind of nuclear explotion, i was thinking. On space engineers we have reactor, but whenever we shoot them, nothing goes wron, so, why not making them explode into a big kind of nuclear reaction. it could hace somekind of "damage-meter" so you have to repair it inmediatly before it explodes. there could even be a "nuclear reaction" option to make it someway of nuke, with a different kind of explotion animation (maybe not a gigantic fungus explotion) but sure a big colorful explotion, which could be bigger and bigger deppending the size of the generator, for example: a small generator (of a small ship) could just cause a explotion 2 or 3 times of a big ship warhead, a small ship big reactor, could cause an explotion of a radius of 30 blocks (of abig ship) and the big ship big reactor could cause an exploion of maybe just a radius about the 60 or 100 blocks.
the advantages: 
It would be more realistic.
it would be a great variation of torpedos or something like that when the players build it.
it would make player be more carefull about how to design them ships with a reactor on them.
in multiplayer, if another player fail protecting the reactor it would be more notorious for the others, (also it would look great).
if you want to have "self destruction" of a ship, you wouldn´t need to fill it of warheads.
the disadvantages:
it would maybe cause some of lag.
if we have a lot of them on our big ships it would be catastrophic.
if we had a station or big ship very complex and we have not the blue prints it would blow a lot of work.
it would replace a little the warheads. For this one, maybe not everyone would like to make nooks of them missiles, they could use also warheads for big jobs.

I don´t know what you guys think about it i jope you like my idea, and hopefully be on game. It would be fun to see into multiplayer we shooting to a ship and suddenly it ecploding.

Hate to break it to you dude, but nuclear reactors can't cause nuclear explosions.  So, to expand upon WhiteWeasel's point, no, it wouldn't be more realistic.

the only way that you'd get an explosion in space would be from pure oxygen igniting or hydrogen and oxygen mixing and then igniting.

Oddly enough (odd because SE is suppose to be based in the future), even the concept of explosive components being made to detonate when hit by another weapon is unreal. With todays material (c-4 and other such explosives) you can safely place it in fire or shoot it and it wouldn't even detonate. In order for it to do so you'd have to place a primer in it or something. But this I guess can be overlooked.

However, what will never happen is a nuclear reactor EVER causing a nuclear explosion. You can try all you want, but no matter what a nuclear reactor cannot explode like it does in the movies.

There are two options if you want an explosion. 1: make a nuclear weapon or 2: Ignite a ships O2 tank... eh, batteries would also be a possible source of a small explosion too but they wouldn't really do much to the ship.

Yeah... space is actually really boring in real life.

It depends entirely on what sort of explosive you are using. Dynamite can be triggered by a bullet. As can Nitrogen triiodide (but for practical purposes, NI3 is not used, since it is so shock sensitive, alpha particles can set it off)
C4, or any other type of Plastique is designed not to explode when shot, thrown, hit, burnt etc. It is designed only to  go off when a specialist detonator is activated (typically it is a shaped charge).
Returning to the point about Nuclear reactors, the only reason why the Chernobyl reactor exploded was because of an insane design for the nuclear pile coolant mechanism. It was a very primitive soviet-era design with no consideration for safety. Cherbonyl blew up because the pressure in the water coolant system did not get relieved.
Three mile island was a similar story. Reactors do not explode. They overheat and the core might melt (hence the term meltdown) but the nuclear pile itself does not explode.
Most fission cores are made of Uranium-235, which is indeed the same power source as was used in the Little boy nuclear device that was dropped on Hiroshima in 1945. Unlike the Little Boy device, however, Fission reactors are designed for controlled emission of neutrons, which have their propagation carefully moderated by graphite control rods or in more modern reactors, special water cooling rods.
If you shot a nuclear reactor, most of the time you'd get ricochet wounds, but if you somehow managed to break through the containment, the worst that would happen is that you'd likely die of radiation poisoning. No explosion.
If you closed the valves on the cooling system and left the pressure to build up.... well that would be a different story, but the explosion would be no worse than an oversized pressure cooking going boom. Only the inside of your ship would now be painted with highly radioactive isotopes that would render the vessel uninhabitable for the next 30 million years.

An explosion is possible in any sense of the word as long as a fuel is present. An example of this is a nuclear element, exactly what this post is based about.

Uranium is not explosive! The only way it does is if an uncontrolled neutron cascade occurs within the mass of Uranium, which requires it to be at critical mass. 
[nuclear-fission-diagram] 
When you guys are talking about "Fuel" you are talking about chemical fuel, which stores chemical energy in its bonds, and releases it in a CHEMICAL reaction.
Fission occurs only when a U-235 atom is hit by a slow moving neutron, which causes it to split and produce more neutrons and trigger an uncontrolled chain reaction.
Burning it, hitting it, shining light on it whatever, unless you have a critical mass of U-235 or another unstable isotope such as plutonium (that drifts into the realms of thermonuclear devices, which we will leave alone for now), NO REACTION WILL OCCUR.

The reactors that explode in movies are Anti-matter reactors

Have you heard of the atomic bomb? If i shot one with a gun it would explode. Nonetheless hit it with an object. In space the only difference would be the lack of a mushroom clod, and a spherical explosion would take place.

If you shot one it should not explode.  You might be exposed to radiation from the hole though.  The explosion only occurs from a high-impact collision slamming two pieces of nuclear material together, reaching critical mass and causing catastrophe.

Actually, I don't believe that's correct.

A nuclear bomb isn't like a conventional explosive that just needs a primer to initiate.  The nuclear reaction happens when a certain amount of fissile material is in close enough proximity.  You've probably heard of the term "Critical Mass"

Nukes are designed to carry a lot of that material, but to keep it separated until it's time to go boom.  The actual explosives in a nuke are pretty small... All they do is push the separate pieces of fissile material (Such as plutonium) together to cause the nuclear reaction.  The trick is timing those explosions so precisely that all of the fissile material gets pushed together at exactly the same time, to create the strongest possible reaction.  This isn't going to happen from a gunshot.

(This stuff is all on Wikipedia)


As for REACTORS exploding... Nope.  Nuclear bombs get that massive blast because of that precise timing that pushes a large amount of fissile material together at once.  A nuclear meltdown doesn't do that... That's why they call it a meltdown instead of an explosion.  I think it's closer to a big fire than an actual explosion... Of course, the radiation still sucks.

It's the difference between popping a balloon with a pin, and just opening it to let the air out slowly.

All that said..... This is a game, not real life.  If Keen wants to make reactors explode, that's their call.  But it wouldn't be more realistic.



EDIT:  TL;DR; = Killacyte is right.

I know this is totally off-topic, but this is something that I think about a lot.

Your description of the events at Chernobyl are nowhere close to accurate. Chernobyl blew up because of design failure, human error, and physical stress. However, it is true that the cause of the explosion was steam over-pressure, and not from rapid burning of uranium.

The minor pop at Three Mile Island was a Hydrogen explosion, but that did nothing more than scare a few workers.

But what happened in Japan? There was a significant explosion at Reactor 3, that completely destroyed, hell, damn near vaporized, the reactor vessel, and produced a rather large oddly-recognizable cloud. The building of unfueled Reactor 4 was also heavily damaged by a different explosion. Hydrogen-Oxygen based explosions couldn't possibly have the necessary blast force to do the kind of damage seen in that disaster.

So, I ask you, what happened there, if not a nuclear explosion of some kind?

Steam explosion. The fuel rods get really, really hot. Around 2800°C / 5000°F. Water vapor and air expand outward, creating a pressure with enough force to break through containment. Stuff proceeds to burst into flames from the temperature.

Edit: And concrete loses strength at around 1200°C. That's bad news for reactor containment.
