Worst case scenario v vodnem reaktorju je torej, da izpari vsa hladilna tekočina? Ali še kaj več? (npr. Three Mile, kjer so enostavno zaprli zadevo in stopljena sredica bo "tlela" še par milijonov let". )

The plant is safe now and will stay safe.
Japan is looking at an INES Level 4 Accident: Nuclear accident with local consequences. That is bad for the company that owns the plant, but not for anyone else.
Some radiation was released when the pressure vessel was vented. All radioactive isotopes from the activated steam have gone (decayed). A very small amount of Cesium was released, as well as Iodine. If you were sitting on top of the plants’ chimney when they were venting, you should probably give up smoking to return to your former life expectancy. The Cesium and Iodine isotopes were carried out to the sea and will never be seen again.
There was some limited damage to the first containment. That means that some amounts of radioactive Cesium and Iodine will also be released into the cooling water, but no Uranium or other nasty stuff (the Uranium oxide does not “dissolve” in the water). There are facilities for treating the cooling water inside the third containment. The radioactive Cesium and Iodine will be removed there and eventually stored as radioactive waste in terminal storage.
The seawater used as cooling water will be activated to some degree. Because the control rods are fully inserted, the Uranium chain reaction is not happening. That means the “main” nuclear reaction is not happening, thus not contributing to the activation. The intermediate radioactive materials (Cesium and Iodine) are also almost gone at this stage, because the Uranium decay was stopped a long time ago. This further reduces the activation. The bottom line is that there will be some low level of activation of the seawater, which will also be removed by the treatment facilities.
The seawater will then be replaced over time with the “normal” cooling water
The reactor core will then be dismantled and transported to a processing facility, just like during a regular fuel change.
Fuel rods and the entire plant will be checked for potential damage. This will take about 4-5 years.
The safety systems on all Japanese plants will be upgraded to withstand a 9.0 earthquake and tsunami (or worse)
(Updated) I believe the most significant problem will be a prolonged power shortage. 11 of Japan’s 55 nuclear reactors in different plants were shut down and will have to be inspected, directly reducing the nation’s nuclear power generating capacity by 20%, with nuclear power accounting for about 30% of the national total power generation capacity. I have not looked into possible consequences for other nuclear plants not directly affected. This will probably be covered by running gas power plants that are usually only used for peak loads to cover some of the base load as well. I am not familiar with Japan’s energy supply chain for oil, gas and coal, and what damage the harbors, refinery, storage and transportation networks have suffered, as well as damage to the national distribution grid. All of that will increase your electricity bill, as well as lead to power shortages during peak demand and reconstruction efforts, in Japan.
This all is only part of a much bigger picture. Emergency response has to deal with shelter, drinking water, food and medical care, transportation and communication infrastructure, as well as electricity supply. In a world of lean supply chains, we are looking at some major challenges in all of these areas.

To ni res. Delal je z zmanjšano močjo, ter popolnoma izklopljenimi zaščitami. Ko so želeli povišati moč, jim je zbezljal.

Mediji bi mogli poročat o njihovem projektnem šalabajzerstvu, da na potresnem obalnem območju ne predvidevajo cunamijev in da jim zasilne agregate zalije voda.......... (7 meterski val)..

Do tega sploh nebi smelo priti........ in to dost pove o natačnosti in varnosti japoncev....

na koncu falirajo na bizarnosti.........

Vir?
Pri izpostavljenosti "radiaciji" je prva stvar da se znebiš vsega kar je lahko kontaminirano .. prvo je to obleka, potem pa pride na vrsto tuš itd.
Tole meni zgleda kot slaba "šala", pa brez zamere!

Oba se motita, glede Černobila. Černobil je podivjal med testnim ugašanjem oziroma zaustavitvijo. Izvajali so test delovanja v primeru izpada reaktorja. Ta test so izvajali popolnoma šalabajzarsko. Problem je bil v tem, da je padla moč reaktorja pod 20% nazivne. Za reaktorje Černobilskega tipa je značilno, da lahko podivjajo med prehodom od 20% do 0% nazivne moči. Za ta prehod imajo posebna navodila. V tem območju jim je hitro zdivjal na 10.000-kratnik nazivne moči. Černobil je zbezljal, med ustavljanjem.

Dober link. In če mene vprašaš, je proti-jedrski lobi danes v svetu precej močnejši kot jedrski. Mini jedrske elektrarne v vsako mesto s 100.000+ prebivalci in naftni lobij je bye, bye.

Še copy&paste povzetka. Tudi po tem se mi zdi začetna predpostavka, da mediji ponovno napihujejo stvari do onemoglosti, zaenkrat pravilna.
