Development of a MELCOR input deck for Fukushima accident: tools and lessons learned

A database collecting all free information regarding Fukushima Daiichi NPP was created. This database was used as a reference for creating a first MELCOR input deck that was shared on a Dropbox folder with MELCOR users that expressed their interest in it. So far only Unit 1 was considered. The input deck was created in MELCOR 2.1 (last available release) with SNAP and without SNAP using Notepad++ text editor. Moreover, an animation file was created with SNAP in order to display main results and better check the simulation correctness. A bug in MELCOR was pointed out and sent to SANDIA. We will present the difficulties in collecting the data, sharing the information, advantages using SNAP and creating a running input deck. The preliminary results of the simulation of the Fukushima accident (Unit 1) will be presented.
