Criterion 1: People and the Environment,
Criterion 2: Radiological Barriers and Controls at facilities,
Criterion 3: Defence in Depth). The highest level among the three becomes the rating of the event. The scale ranges from level 0 (No safety significance) to level 7 (Major accident). (Ref. INES User’s Manual 2008 Edition
Units 1, 2 and 3 of Fukushima Dai-ich - It is considered that such total loss of cooling function led to the reactor core to be damaged, due to the inability to provide service by the Turbine Driven Pump resulted from the temperature rise in the Suppression Chamber caused by the operation of the pump. The leakage of radioactive materials continues. (Temporary rating of INES*)
Criterion 1 - TBD
Criterion 2 - 5
Criterion 3 - 3
The rating on Criteria l and 2 are to be determined later because the event is not led to be ceased
Meanwhile, TEPCO was considering using a German-made high-pressure pump capable of spraying water on a distant target with a boom longer than 50 meters, according to TEPCO sources. The pump is used to pour concrete at construction sites.

Instead, we have seen rising temperatures. Therefore the control rods are insufficient to damp down the reactor and the reactors are still running, so the reactors were likely operating in a 'breeding' configuration and we are being lied to.
If the melted rods pool, and the reactor was running in a breeding configuration, the pool can go critical or even supercritical. This means that they could detonate!
My bad, Red; I might have missed that; after 250+ pages here plus watching and reading about Chernobyl it gets a little confusing, my friend.

I was referring to plutonium in the fuel mix, as in MOX fuel. There is always some plutonium in a uranium decay.
Sorry, thought i was clear about that distinction but apparently not.
