FUKUSHIMA CORIUM

a commentary by Rik:

A recent article on Enenews ( http://enenews.com/ ) said that the melted fuel
mixture under the reactors in Fukushima was likely to be remelting.

A friend asked me to comment.

As I understand it, the corium, (a mixture of the melted nuclear fuel itself, the zirconium tubes that held the fuel pellets, and the steel racks that held the fuel bundles, all melted together) has slumped to the floor of the PCV, (pressure containment vessel) in the form of several large blobs, totalling some 130 tons per reactor. By luck rather than good management the PCVs of each of the three reactors ruptured above the level of the blobs, so they are pretty much covered by water. Several tons an hour of water is still injected into each reactor, so it must be boiling off still. So the molten corium would have formed a crust on the outside, where it is in contact with the water, but inside this crust, the corium would probably be still liquid or partly liquid, due to the heat produced by the on-going splitting of uranium atoms when struck by a neutron, in turn firing off more neutrons, and by the continued decay of the fission by-products. In other words, due to the occasional resumption of fission within the corium, it will sometimes probably again melt.

As wikipedia says: –
‘Heat is produced by the radioactive decay of fission products and materials that have been activated by neutron absorption. This decay heat-source will remain for some time even after the reactor is shut down.’

It is not that a dramatic new stage has been reached in the Fukushima disaster. The corium has been probably melting, on and off, for the whole four years.

Fukushima witness accounts, English translation in digital format

‘Fukushima Radiation: Will You Still Say No Crime Was Committed?’

by 50 Complainants for Criminal Prosecution of the FUKUSHIMA Nuclear Disaster

Norma Field (Translator), Matthew Mizenko (Translator)

This booklet is a translation of statements by 50 citizens who were residing in Fukushima at the time of the triple disaster of March 11, 2011.
They range in age from 7 to 87, and they wrote these statements as part of the criminal complaint filed with the public prosecutor by the Fukushima Complainants for Criminal Prosecution of the Fukushima Nuclear Disaster. What, exactly, is a criminal complaint, and who is a “complainant”? In this case, the complaint is the formal legal procedure initiated by citizens in response to the failure of both prosecutors and police to investigate the criminal liability of Tepco and government agencies for their roles in the nuclear disaster. The group complaint, filed at the office of the public prosecutor, is a demand for investigation and indictment of the responsible parties.

Because this is a criminal and not a civil procedure, these citizens are “complainants” rather than “plaintiffs.”

True, some of the Complainants are also plaintiffs in the various civil cases generated by the Fukushima disaster, such as the “Give Us Back Our Livelihood, Give Us Back Our Community” Fukushima Nuclear Power Plant Lawsuit; “Denounce Nuclear Power Generation: Redress for the Villagers of Iitate”; or “The Fukushima Collective Evacuation Trial for the Right to Education in a Safe Place.”

Although several Complainants in this booklet draw a connection between the failure of the state to pursue criminal liability and the difficulty of getting anything resembling adequate compensation from Tepco, it is important to keep in mind that as Complainants, they do not stand to gain anything individually even under the best-case scenario: if, after all the prosecutorial refusals, an indictment is brought, a trial held, and some parties found to be criminally responsible for the nuclear disaster.

Rather, the Complainants are driven by grief, anger, and incredulity. So much harm had been inflicted, with demonstrated negligence not only leading up to the disaster but in its aftermath, with dire consequences not only for themselves but flung far into the future. After all this, how could it be that no one was held responsible? How could it be that the police, let alone the prosecutors, had not conducted a thorough investigation? Did the rule of law not prevail in Japan? As victims bearing witness, they seek to exercise their responsibility to future generations, that the calamity not be repeated, that the harm be contained by all means possible.’
