[3D06] Prediction of decay heat of fuel debris considering volatilization of fission products

*Keisuke Okumura1, Eka Sapta Riyana1, Wakaei Sato2, Hirobumi Maeda2, Manabu Fujita3 (1. JAEA, 2. NESI, 3. JPC)

Keywords:Fukushima Daiichi Nuclear Power Station, Fuel Debris, Decay Heat

For the fuel debris of the Fukushima Daiichi Nuclear Power Plant, the time-dependent change of decay heat from the accident time to the future and major contributing nuclides were estimated in consideration of volatilization of fission products at the time of the accident.
