The corium issue • Corium = the liquid or solid slag within or below the reactor pressure vessel (RPV) resulting from a melting of fuel rods, cladding, steel structures, and subsequent chemical reactions and physical events • If the corium melts through the steel RPV to the concrete basemat of the primary containment vessel (PC or PCV), coriumconcrete chemical reactions may include gases including CO, CO 2, H 2 • There is a further possibility of corium passing through the basemat if the PCV is ruptured (e. g. by H 2 explosion) or if melted by the corium 47

Inculcating “a false sense of TEPCO’s competence” “It is not clear why TEPCO chose

Inculcating “a false sense of TEPCO’s competence” “It is not clear why TEPCO chose not to release the key instrumentation records of RPV and fuel core conditions during and immediately following the tsunami strike until 15 May. Certainly, TEPCO would have had access to these records at the time… The role and judgment of NISA in presenting the daily updates of reactor conditions is also questionable, particularly in that it must have been aware that Unit 1, at least, had undergone a full melt within 16 hours or shorter of the earthquake but then, even in this certain knowledge, why it continued to publish its daily but unrelated readings of the RPV shell temperatures is baffling. At best, what must be construed as mismanagement of information has frustrated observers and analysts following progression of the Fukushima Daiichi incident. At worst, the information withheld most likely resulted in ill-informed and incorrect decision-making and management both on and off the Fukushima Dai-ichi nuclear site. Source: John H.

Convention on Nuclear Safety • Need for fundamental challenge to nuclear sovereignty embedded in Convention on Nuclear Safety – CNS parties last week deferred Fukushima review meeting till August 2012 • • IAEA on the Convention: “The Convention is an incentive instrument. It is not designed to ensure fulfillment of obligations by Parties through control and sanction but is based on their common interest to achieve higher levels of safety which will be developed and promoted through regular meetings of the Parties. The Convention obliges Parties to submit reports on the implementation of their obligations for "peer review" at meetings of the Parties to be held at the IAEA. This mechanism is the main innovative and dynamic element of the Convention. ” – http: //www-ns. iaea. org/conventions/nuclear-safety. asp 84
