Reactor go boom, wth?

There's your problem. Your reactor is a Mark IV and had a reason to explode.

If you haven't seen part 5, starting around 4:30,

Yes, his nuclear reactor exploded as well.

Also: blast, RichardG beat me to the punch (sort of).

You watched yogscast and followed a design they used which they got from a random person on the internet... I might as well have told you to fill your reactor with only uranium cells and said "This way you get 2,400 EU/t, which beats any other generator in known history" and fail to mention that no matter how much water you have around it, it is still going to explode (VIOLENTLY) in 6 seconds.

Oh well, now you have learned to not blindly follow what yogscast says. And you have learned that reactors can (and will) explode if you don't use them properly.
There is a whole plethora of information on them in this forum section. Feel free to read and learn all about them and then return to your design.

And use that Talonfiremage site to check your reactor designs. If it says anything other than "Mark I" then your reactor can explode.

There are non Mark I designs which have /other/ engineered things which prevent explosion (cut-off timers, switched use, other such things); however all of them /can/ explode if the engineering controls fail.

That's exactly what I was thinking. Also, never count on anything but source blocks of water to provide ongoing cooling! Even containment vessels that are cooled by flowing water have it supplied by an un-reachable source (meaning outside the range of what the reactor can evaporate due to heat). I don't think the ocean is a good place for it (besides, what are you planning to power out there?). See the missing water where the reactor was? That just goes to show that blocks in an ocean don't replenish themselves the same way as a man-made vessel full of source blocks.

Simple version; there is no safe way of high EU.

You will require either buildcraft + additional pipes mod OR Redpower2 to build a Constantly Applied Reusable Use Coolant (everyone else but me calls it a CASUC, except I argue no resources are being consumed (the water involved regenerates) and thus the description isn't accurate) reactor which is cooled by say, water buckets. (In the build planner you'll want one that is missing one/two chambers (depending on your build plan) and has a multiple of 250 excess heat per second before adding buckets to match that, make sure you change the buckets per second option+tick to the correct value; oh and building it... you'll want to experiment with feeding it buckets at that rate or better. RP2 is very easy to do that in.)

An alternate plan if not using either of those mods is explored in my nuclear battery thread; but there you'd need to build and route power from ~4 reactors per 128 load; though one design could almost do it with 2 sets of reactors (the costs are higher though so you'd probably want to go the other way).

However there's also a glitch in 1.42 which causes a crash at the end of reactor cycles. Supposedly a patch is known and a bugfix release is expected 'soon' (probably a safe bet before Xmas).

With redpower you can run this like a mk1:

Through that will require a ton of recourses and alot of time to get it working properly. My old casuc reactor is a good place to start (link in sig). With retrievers you can go way faster than with filters.

You could do it in many different ways. Since you have buildcraft installed you can make tree farms that automate a power plant of 40 generators. I recommend the BC addon "additional pipes" which makes working with BC pipes a whole lot easier.
There are many other possibilities of course but most of them call for redpower 2 to be installed or another kinds of power conversion mod...
If you wanna see what a 1740 EU/t CARUC (hi Evans!) design looks like then see this video:

I have yet to see anyone else do anything that produces as much power... Mainly due to nuclear reactors being bugged at the moment

holy wow that's an insane reactor. Nicely done and designed but wow.

You trusted a dwarf known for building bridges out of TNT? Be more careful.

This is a slightly safer design. But you can only run one cycle before cooldown.

Both links are the same...
