[2J04] Development of a handy criticality analytis tool HAND for fuel debris retrieval

*Kenichi Tada1, Takao Sakino1 (1. JAEA)

Keywords:Fukushima Daiichi nuclear power plant accident, Fuel debris, Decommissioning, Criticality safety, HAND

The estimation of the criticality safety of fuel debris is imperative to prevent radiation exposure of workers. We developed a handy criticality analysis tool HAND to quickly estimate the criticality of fuel debris without expert knowledge of reactor physics. This presentation explains the overview and calculation example of HAND.
