Description
The time-dependent temperature at the location of the electric equipment important to safety must be established for the design basis accident during or following which this equipment is required to remain functional. In the Kori Unit 1 auxiliary building, electric equipment such as 120V vital instrument panel(XPN- 218) and SFP MPP40A/B local panel(XPN-25) is installed at EL. 20 ft area but the thermal hydraulic conditions and its influence on the equipment have not been properly investigated under CVCS letdown line break accident conditions. The objectives of this study are to examine closely the influence of CVCS letdown break accident at the location of electric equipment in the Kori Unit 1 auxiliary building and to assess whether the equipment maintains its function under the accident conditions
