ジャーナル フリーResults of recent investigations of the greenhouse effect are reviewed. The temperature rise due to doubling of CO2 is estimated to be 3.0±1.5°C. Other trace gases also contribute to the warming significantly. Climatic records of the past century are not inconsistent with the warming hypothesis. Environmental effects of the warming are also discussed. The possible drought in the United States is suggested, which could affect the Japanese life seriously. The possible disappearance of upwelling regions in the world oceans is also pointed out. However, the most serious problem is melting of polar ice, particularly the catastrophic disintegration of the West Antiarctica, which could lead to the submergence of the world coastal regions. It is emphasized that introduction of nuclear energy could avoid this disaster, and hence nuclear energy has a global significance.抄録全体を表示PDF形式でダウンロード (511K) -

ジャーナル フリーSince 1980, the Research Program on Thorium Fuel has been performed under the support of Grant-in-Aid for Energy Research of the Ministry of Education, Science and Culture of Japanese Government on the university basis including several tens professors. The main results have been published in the English-written report, "Research on Thorium Fuel (SPEY-9, 1984)".
This report describes the outline and review of the symposium held on January 31, 1984. It consists of nuclear data, reactor physics, thorium fuel, irradiation of thorium, down-stream, biological effect, molten salt reactor engineering and others. It has been the first trial to perform such a big systematic cooperative studies in nuclear field on the university basis in Japan.抄録全体を表示PDF形式でダウンロード (507K) -

ジャーナル フリーEnhancement of forced convective heat transfer in a narrow concentric annulus was performed by turbulence promoters in order to improve the heat removal from High Temperature Gas-cooled Reactor, Gas-cooled Nuclear Fusion Reactor and other narrow flow passages. Present experiments, which were different from the conventional research, were carried out to examine the effect of the turbulence promoters on the inner insulated wall opposite the outer smooth heated wall by changing the ratio of the pitch and the height P/ε (from 5 to 60), the ratio of the height and the space ε/ε' (from 0.2 to 2) and the type of turbulence promoters. Experimental results were arranged for the local heat transfer coefficient distribution on the smooth outer tube, the average heat transfer coefficient, the friction factor and the thermal performance. Five kinds of evaluation for thermal performance were presented: The ratio of heat transfer coefficient with and without turbulence promoters at three conditions, (1) constant Reynolds number, (2) constant pressure drop and (3) constant pumping power, additionally, (4) pumping power reduction at constant heat transfer coefficient and (5) working ratio. An example of a fuel element of HTGR with turbulence promoters was indicated as an application of present results.抄録全体を表示PDF形式でダウンロード (534K) -

ジャーナル フリーOxidation by the catalyst bed with a metal oxide and subsequent adsorption to the porous dehydrative reagents is supposed to be effective process for scavenging tritium from an inert atmosphere. Use of spongy copper oxide or wires of copper oxide is not recommended to use as the metal oxide catalyst from the view point of mass transfer because of sintering and of limited effective surface area. Use of hopcalites and copper oxide-kieselguhr are examined in this study and it is concluded that hopcalites are more suitable as the metal oxide catalyst because they not only remain the oxidation power on hydrogen isotopes even at an ambient temperature, but also show a negligible drop in oxidation performances with repeated regeneration. The effective temperature is about 400°C for hopcalites and 300-600°C for copper oxide-kieselguhr to use as the oxidation bed of tritium.抄録全体を表示PDF形式でダウンロード (540K) -

ジャーナル フリーSeven aromatic lubricating oils which include four alkyl diphenyl ethers, a silicone oil and two polyphenyl ethers were irradiated with 60Co γ-rays at room temperature in vacuo and under bubbling oxygen. The irradiation was carried out at a dose rate of 1×106 rad/h up to 3, 000Mrad. Viscosity and total acid number were measured after the irradiation. Radical yield of each sample was obtained by means of ESR for the sample irradiated at 77K.
The relations between %CA and the viscosity change, total acid number, and radical yield were examined. The larger %CA resulted in the smaller viscosity change, total acid number and radical yield. Aromatic lubricating oils were more radiation-resistant than mineral oils. Among the aromatic oils, m-phenoxyphenoxy diphenyl showed the highest stability for radiation.抄録全体を表示PDF形式でダウンロード (419K) -
