摘要

Responding to the TEPCO's Fukushima Dai-ichi nuclear power station (1F-NPS) accident, the design study was carried out to enhance cooling function of fuel handling system (FHS)for Japan sodium-cooled fast reactor (JSFR). Design measures to maintain an FHS cooling function even in case of Design Extension Conditions(DECs) are studied; such as alternative cooling systems which are independent and diversified from design basis cooling systems. Based on effectiveness evaluations, it was confirmed that these measures have adequate availability against the postulated design extension conditions.
