Study on improvement of safety for accident conditions in spent fuel pool, 9; Temperature evaluations of BWR fuels by three dimensional steady-state heat transfer analyses

Goto, Daisuke*; Tojo, Masayuki*; Kobayashi, Kensuke*; Nemoto, Yoshiyuki ; Kaji, Yoshiyuki

Steady-state heat transfer analysis method for the BWR spent fuel rack system was adopted to evaluate the cladding temperature in spent fuel pool accident condition. The cladding temperature seems to depend on spent fuel distribution, and the evaluation results were compared with the results obtained by using the MAAP. Ideas for the deployment of the fuels to prevent temperature elevation during the spent fuel pool water level decrease will be discussed.
