Use this mapplet to see what a nuclear disaster would look like for Fukushima nuclear plant, 3 reactors go. All 3 reactors combine put out like a 2 GW, not sure how that would equal in tons.
I checked out a 50 Mt nuke and it doesn't look so good for anyone within 40 km of the plant, best bet people better be 100 km away if this thing decides to really go KABOOM.

You can't relate this at all. A nuclear weapon works in a totally different fashion than this.
A meltdown is a problem because of the pressure it can build up inside the reactor vessel. If that pressure is unable to be released you can have a catastrophic failure of the containment vessel and the reactor itself will be blown to bits by the pressure inside. Its NOT a nuclear explosion.
The type of fuel inside a reactor is not weapons grade (most of the time, unless its a plutonium breeding reactor, but even then the amounts are so low and in such a low density it doesn't matter). Uranium fuel, or MOX (which is a mix of Uranium and reclaimed weapons grade plutonium) can not reach critical mass, they just come close (but that is very relative, close is not even near what it would take to create a run-away criticality).
So please, do not scare monger with links like that. The possible destruction, physically, by these reactors having a catastrophic failure is not even close to a 50MT nuclear explosion. You can not even begin to comprehend the differences (I am talking about, a fireball many miles in diameter, people getting instant third degree burns 30-40 miles away, blast damage stretching for hundreds of kilometers). The only comparable area would be on fallout, which is radioactive material that is taken into the atmosphere and deposited many miles away, irradiating those areas for potentially long periods of time.
