Uncertainty quantification of Doppler coefficient for MONJU

Chiba, Go*; Hazama, Taira ; Kinjo, Hidehito*; Nishi, Hiroshi; Suzuki, Takayuki

Uncertainty of Doppler coefficient is quantified for a Monju core, reflecting present knowledge. Various uncertainty sources are evaluated: (1) Nuclear data and numerical method, (2) Fission product nuclear data, (3) Control rod position, (4) Approximated treatment of temperature dependence, (5) Averaged fuel temperature, (6) Approximated treatment of temperature spatial distribution, etc. Resulting uncertainty for Doppler coefficient is estimated at 11.7% for the 2 reliability.
