Claiming, as you do that "... they knew already that MOX didn't have a thing to do with the #3 explosion..." is quite a bold statement without any science to back it up.
There's PLENTY of science to back up that the MOX had nothing to do with it.
First, MOX can't explode. MOX is only about 7% plutonium; that percentage is WAY too low. Saying that MOX is explosive is about as implausible as saying that a mixture of 1% gasoline in 99% water is explosive.
The Comprehensive Test Ban Treaty Organization is setup to test for nuclear explosions. They are the United Nations organization that is setup to police the CTBT when / if it goes into effect. They have to be able to distinguish between a nuclear explosion and the effluent from a reactor accident.
Suppose there was a country that wanted to make nuclear weapons and test them even though they signed the CTBT promising not too. If they had a nuclear reactor, and they designed a nuclear bomb and tested it, the fallout from the explosion would be detected outside their country. They could then just claim, "We had a reactor accident, like Fukushima. That's where the fallout came from". How could CTBT prove that they actually exploded a bomb in violation of the Treaty.
It turns out that bombs use a fast or high-energy neutron spectrum; they have to. Reactors mostly use a slow or low-energy neutron spectrum. The distribution of fallout products from fissions depends on the energy of the incident neutrons. Therefore, the fallout from a bomb looks different in composition than the fallout from a reactor accident. That's how CTBTO can check to see if the fallout is from a nuclear explosion or a reactor accident.
In the case of Fukushima, the CTBTO says that the fallout they measure was from a damage reactor, and NOT a nuclear explosion like that IDIOT Gundersen claimed:

The CTBTOs monitoring system, custom-tailored to detecting nuclear explosions, can detect a range of radioactive isotopes, among them Iodine-131 and Caesium-137. Looking at the ratios between the various radioactive isotopes in particular Caesium-137 enables the source of the emission to be identified. In the case of the current readings, findings clearly indicate radionuclide releases from a damaged nuclear power plant, which is consistent with the recent accident at Fukushima in Japan.
BTW, since you obviously don't know the requisite science; you should refrain from telling those that do know the science what has / has not been proven by the science. You are way over your head.
