[2K14-16] Light Water Reactor Behavior Under Accident Conditions

Tue. Mar 27, 2018 3:50 PM - 4:40 PM Room K (U3-311 -U3 Building)

Chair: Hidemasa Yamano (JAEA)

4:20 PM - 4:35 PM

[2K16] Analysis of MCCI phenomena by MELCOR and SAMPSON

(3)Study on Heat Banance of Fuel Debris in Wet Cavity

*Masashi Himi1, Hidetoshi Morita1, Koetsu Ito1, Yoshihiro Ide1, Koichi Nakamura2 (1. Advancesoft co., 2. CRIEPI)

Keywords:severe accident, corium-concrete interaction, heat balance, core debris

We examine how the temperature of the fuel debris falling into the wet cavity varies depending on the heat balance of decay heat, oxidation reaction heat, thermal radiation and heat transfer due to cooling water.
