ジャーナル フリーThe economical status of Liquid Metal Fast Breeder Reactor (LMFBR) which is the succession of Light Water Reactor (LWR) from a view-point of beneficial utilization of the uranium resource is not still competitive with those of LWR, thus we need further efforts to reduce the cost for the plant construction and for the fuel recycling. On the other hand, the requirement for the burning or incinerating the TRU nuclides (long-life radioactivities) which are the products from the operations of LWRs has also been raised. Recently, in accordance with the foregoing needs the studies of Actinide Recycle Fast Reactor (ARFR), a concept of the power generation/TRU incineration systems, are progressing. In this paper the emphasis is on the proposal of the molten chloride salt fuel (MCSF) option for the power generation/TRU incineration systems. The MCSF system has the potential for leading us to a great deal of simplification for the fuel recycling, thus contributing to the solution of the major remaining problems for the ARFR (or LMFBR) option.抄録全体を表示PDF形式でダウンロード (8360K) -

ジャーナル フリーJapan has fifty nuclear power plants in operation and some of them has been operated more than twenty five years. It becomes more important to develop maintenance technologies to prevent unscheduled outage. We have developed wet shot peening system to change tensile stress to compressive stress around the weld preventing stress corrosion cracking (SCC).
Together with the stress improvement technology, we have developed multipurpose remote handling equipment to execute the tasks required in a core area and an annulus area.抄録全体を表示PDF形式でダウンロード (9711K) -

ジャーナル フリーA numerical analysis has been performed on developing turbulent flow in a circular pipe containing two rods located off-center. In calculation, an algebraic stress model was adopted in order to predict Reynolds stresses precisely, and the boundary-fitted coordinate system was introduced as the method of the coordinate transformation. Calculated results were compared with the experimental data available. The calculated profiles of secondary flow and Reynolds stresses for developing turbulent flow were investigated in detail. As a result of this calculation, it was found that the calculated distributions of the streamwise velocity and friction velocity are predicted well within 3% error range. Although the secondary flow along the wall of the outer circular pipe is not observed in the experimental data, the calculated result suggested that its secondary flow is generated by anisotropic turbulent in the region between off-center rod and circular pipe. The generation mechanism for its secondary flow was presented by evaluating the production terms in vorticity equation quantitatively. But more active research is necessary to make clear whether the predicted secondary flow exists or not.抄録全体を表示PDF形式でダウンロード (14328K) -
