Sake is a useful tool for promoting local industry, but sake consumption has been decreasing year by year. In Gunma prefecture, the Gunma industrial technology center has playing a central role in breeding original sake yeast. Furthermore, for quickly corresponding with the needs from market, JAEA have tried breeding of sake yeast by ion beam breeding technology for development of distinctive sake yeast and its practical use while closely coordinating with the Gunma industrial technology center. As a result, the high ethyl caproate producing novel sake yeast were obtained.

In order to develop the core damage evaluation technology (level 2 PSA) for sodium-cooled fast reactors, we develop the new analysis codes of post accident material relocation phase and of ex-vessel events, and we develop the technical bases that is necessary for level 2 PSA. In this presentation, summary and scope of the entire study is introduced as a part of the 4 series presentations.

To develop a core damage evaluation technology (level-2 PSA) in sodium-cooled fast reactors, a new analysis method is developed for core-material relocation phase and internal containment vessel event. This study also develop technical basis necessary for the level-2 PSA.

Development of imaging techniques with pulse neutrons were started using the NeutrOn Beam-line for Observation and Research Use (NOBORU) of J-PARC at December 2008. The results in the first three months, future research plans and discussions on a new imaging facility in J-PARC are shown.

We have previously obtained high ethyl caproate producing Sake yeasts "No.227" and "No.1333" by ion beam breeding. The fatty acid synthase genes (
and 
) and the fatty acid esterase genes (
and 
) might be involved in the higher production of ethyl caproate in the mutant strains. In this study, to identify the mutation sites of the mutant strains, each gene locus was sequenced. For the , and loci, all the mutations found in mutant strains are nonsense mutations, suggesting that these mutations did not involved in the higher production of ethyl caproate. On the other hand, strains No.227 and No.1333 carried G/A and A/A mutations in gene at nucleotide position 3,748 as heterozygous and homozygous states, respectively. This result strongly suggested that the higher production of ethyl caproate in strains No.227 and No.1333 is attributed to a dominant mutation in gene.
