ジャーナル フリーOf the environmental radiation monitoring around nuclear power station, conducted by Fukui Prefectural Government, objective, program and results are described in this paper.
Improvement of public relation is the most important objective, taking into consideration the fact that radioactivities released from the nuclear power stations are so small that it cannot be detected in the environment around most of the nuclear power stations.
One of the features of our monitoring program is use of inedible indicator plants for estimating the upper limit of radionuclides concentration accumulated in agricu1tural and marine products.
The results of the measurements in 1981 showed that the exposure of the public individual living in the vicinity of the nuclear power stations was far below 5mrem/yr, the guide line for light water reactor.抄録全体を表示PDF形式でダウンロード (475K) -

ジャーナル フリーAn experimental system for tritium gas in small scale handling has been designed and constructed which consists of glove box, tritium removal system, tritium gas generating system and tritium gas subdivide system. The volume of the glove box is about 2m3, and the processing flow rate of the tritium removal system is 3.8m3/h. Tritium generating system is composed of a heating furnace, a gas reservoir, an ionization chamber and a vacuum pump. Subdivide system is equipped with a teopler pump for taking out some parts (less than 50mCi) of tritium gas from the tritium generating system or from carrier free tritium ampoule to out of the glove box. The results of performance test showed that all these systems can be operated satisfactorily for each object. The leak rate of tritium from the connecting parts of tritium ampoule was confirmed to be very small, thus the tritium ampoule could be used with high safety.抄録全体を表示PDF形式でダウンロード (655K) -

ジャーナル フリーVery High Temperature gas-cooled Reactor (VHTR) reference fuels were irradiated in an in-pile gas loop (OGL-1) and irradiation performance of the fuels taken out from OGL-1 fuel body was studied by post-irradiation examination. In the examination, dimensional and weight changes of the fuel compacts, and failure fraction of coated particles included in the compact were measured, and also ceramographic and X-ray radiographic observations on the fuels were carried out. Major results of the examination are as follows; relation between shrinkage of the compact and fast neutron fluence was obtained, but influence of irradiation temperature on the shrinkage was not detected. Weight change of the compact was hardly recognized. As for failure of the coated particles, the compacts taken out from 3rd fuel body revealed relatively high failure fractions, although the fractions were under the allowable limit in VHTR design. The other compacts showed good performance under irradiation.抄録全体を表示PDF形式でダウンロード (13445K) -

ジャーナル フリーAlthough the finite difference method has been applied to various flow problems, it is well known that this method occasionally encounters difficulties for the analysis of the problem whose configuration is complicated. The authors, adopting the penalty finite element method, developed the two-dimensional thermal convection analysis code formerly. In this paper, it is extended to the axisymmetric and the three-dimensional code so that the three-dimensional effect can be taken into consideration to analyze variety of problems with high accuracy.
In the penalty finite element method, the reduced integration technique is applied for the penalty term to avoid the phenomenon called locking. In this paper, it is shown for the axisymmetric analysis that the accuracy is lost in evaluating the penalty term by 1×1 Gauss point for the 4-node element, and that exact integration by 2×2 Gauss points leads the solutions to the locking. On the contrary, it is observed that the 9-node element with 2×2 Gauss points gives good solutions for various types of problems. And performed also is the three-dimensional analysis for a cavity flow and a duct flow.抄録全体を表示PDF形式でダウンロード (378K)
