ジャーナル フリーA new organization, which is responsible for the disposal of high-level radioactive wastes, will be established in around 2000. The waste disposal will be promoted on a full scale after that. Before implementing the waste disposal, it is necessary to establish the related techniques. Therefore, a series of issues for each step of waste disposal, such as the selection of candidate sites, site characterization, design and construction of repositories, safety assessments, emplacement of wastes, closure of repositories, and management after closure, which are to be promoted by the implementation body, were studied from technical viewpoints. The consideration for design construction, assessment, etc. at each implementing step is offered as the result. The present paper describes the basic concept related to the disposal project.抄録全体を表示PDF形式でダウンロード (7080K) -

ジャーナル フリーThe factors, by which the modern engineering ethics has been profoundly affected, were classified to three categories, namely mental blow, the destruction of human function and environment damage. The role of atomic energy engineering in the ethic field has been shown in the first place. It is pointed out that it has brought about the mental blow by the elucidation of universal truth and discipline and the functional disorder by the power supply. However, the direct effect of radiation to the human kinds is only a part of the stresses comparing to the accumulation of the social stress which should be taken into account of by the possibility of disaster and the suspicion of the atomic energy politics. An increase in the multiple stresses as well as the restriction of criticism will place obstacles on the promotion of atomic energy.抄録全体を表示PDF形式でダウンロード (3811K) -

ジャーナル フリーIt is expected that light water reactors (LWRs) will continue to play a dominant role in the nuclear power generation even after the change of the century. Development of future LWRs suitable for this perspective has been promoted both in Japan and in other countries. This paper focuses on the studies on feasibility of extended operating cycle of the Next Generation PWR, one of the future types of LWRs.
First of all, extended operating cycles in oversea countries were studied, and then the operating cycle length suitable for Japanese plants was estimated. Overall feasibility of long operating cycles for the Next Generation PWR of 1, 700M We-level was studied from engineering, economic and equipment integrity standpoints in this study. As a result of the studies, the 18 and 24-month operating cycles are proved to be the desirable cycle patterns when the electric demand in Japan is taken into account. Possible economic improvement compared with the current operating cycles (of 15 months at maximum), as well as sufficient technical feasibility of the 24-month cycle, has been confirmed.
This paper also points out, as a future objective, that it is desirable to develop fuels with the burnup higher than the current limit of 55GWd/t and to raise the enrichment limit of 5%.抄録全体を表示PDF形式でダウンロード (6148K)
