Hi Randy,

We’ve discussed internally, and the documents are approved for distribution to IRSN (but not for further distribution outside of IRSN). .Attached are the cover pages to the documents under consideration. Do you have them readily available to send to IRSN? If not, I can go through ADAMS and collect the documents one by one.
Thank you,

Dear Randy,

As you may imagine, we are looking at the possible accident progression in Fukushima power plant. A t the time being we are looking at the problem of the spent fuel storage pool of reactor #4.

We will make evaluations of the consequences of the loss of water for different scenarios of emptying, calculate heat-up and associated source term.

You certainly have made such evaluations in the past using MELCOR calculations. So i have the following question: would it be possible for you to send us some results so as we can make cross-comparisons with our results.

You can certainly understand that this is an urgent request.
