アブストラクト
Small long life fast reactor with CANDLE burn-up concept was investigated. The core with 1.0m radius, 2.0m length can realize CANDLE burn-up with nitride (enriched N-15) natural uranium as fresh fuel. Lead-Bismuth is used as coolant. From equilibrium analysis, we obtained the burn-up velocity, output power distribution, core temperature distribution etc. The burn-up velocity is less than 1.0cm/year that enables a long life design easily. The core averaged discharged fuel burn-up is about 40%. For more understanding about the effect of the coolant to fuel volume ratio, the comparison between five cases is made. The coolant channel radius is different from each other, while fuel pin pitch is fixed. Further, the comparison is made with fixed coolant channel radius and different fuel pin pitches.
