What i´ve done:

First things about Fukushima I nuclear accidents. Saw this and expected deaths, which will sorrowful come true. Written some knowledge to help, that this and further nuclear accidents won´t go as bad as Chernobyl. But as clear as water-cooling failed for now 2 weeks, nearly nobody understands a thing how to improve and stop radiation and deaths.

Minimum triple deplorable tragedy: No brain to make it right, no brain to understand the warnings for decades and no brain to learn. Especially from me :-).

Italics content is fully by me. Think its important and the best solution. Somehow proud about knowing that.

Liquid metal cooling: On 17 March, KyivPost reported that a Ukrainian group of specialists who were involved in the aftermath of the Chernobyl nuclear disaster proposed low-melting and chemically neutral metal, such as tin, to cool the fuel rods even if molten or damaged. Chopped tin can be injected in the reactor through the existing cooling water pipes with compressed inert gas, helium or argon. Melted tin creates a crust (low vapor pressure), cools the reactor and delays the decay products recovery. Liquid metal cooled reactors need no pump and due to no pressure and a wider temperature-range are less likely to a Loss-of-coolant accident.	This solution has similarities with the 2400 metric tonnes of lead (see also Lead-cooled fast reactor) used to successfully cooling and covering the Chernobyl nuclear plant but avoids the toxic lead. Liquid metal cooled reactors were used in several Soviet submarines which shows additional basic feasibility. It also avoids the danger of additional explosions caused by water breaking down to hydrogen and oxygen starting at temperatures around 800 °C due to Thermolysis. A team of Ukrainian nuclear specialists is ready to fly out for realizing this in practice. The Japanese Embassy was informed.
"Sarcophagus": On 18 March, Reuters reported that Hidehiko Nishiyama, Japan's nuclear agency spokesman when asked about burying the reactors in sand and concrete, said: "That solution is in the back of our minds, but we are focused on cooling the reactors down."	Even 1800 metric tonnes of sand and clay used in the Chernobyl disaster acted worse as thermal insulators and accumulated heat. So first a non-evaporating coolant like liquid (and minimum surface-frozen) metal has to be applied, and after temperature has decreased, a sarcophagus.

Total emission

The Central Institute for Meteorology and Geodynamics estimated the total emissions of iodine-131 from 12 to 15 March at 4x10¹⁷ Bequerel, which is about 20% of the total emissions during the Chernobyl disaster. The emissions of Cesium-137 of the first 4 days were estimated to 3.3 x 10¹⁶ Bq, which is about 50% of the total emissions during the Chernobyl disaster. According to this data and data from Institut de radioprotection et de sûreté nucléaire a scientific consultant prepared for Greenpeace an analysis in which he rated the total Fukushima I accident at INES level 7 by March 24th. This can be quite easily roughly revised with the International Nuclear and Radiological Event Scale (INES) User´s Manual.
