ジャーナル フリー原子力エネルギーの開発においては従来の中性子データに加えて,核構造や崩壊データの必要性が増してきた。この種の核データについても1976年に編集・評価・普及を国際協力で行うためのネットワークが構成され,その活動が始まっている。本稿では,この協力システムで採用されている評価済み核構造データファイル(Evaluated Nuclear Structure Data File)と核構造文献ファイル(Nuclear Structure Reference File)の性格,内容,評価基準,利用の見通しなどを概説する。抄録全体を表示PDF形式でダウンロード (663K) -

ジャーナル フリーThis paper reviews current status of research and development on special instrumentation sensors and some instruments for high temperature gas-cooled reactors.
Main topics described are high-temperature neutron detectors for the nuclear instrumentation system, high temperature thermocouples for in-core temperature-distribution monitoring, ex-core process sensors for the reactor plant, impurity monitors in helium cooling gas, fuel failure detection method, measurement of fission product plateout and surveillance of reactor components.抄録全体を表示PDF形式でダウンロード (7672K) -

ジャーナル フリーA tentative set of group constants is presented for the C-core of the Kyoto University Critical Assembly (KUCA), which is light-water moderated, and which can furnish loadings of three different pitches (2.96, 3.49 and 4.54 mm). The fast group constants were prepared by the familiar computer code “UGMG-42”, which employs continuous slowing-down model; thermal group constants by “THERMOS”. Special care has been taken so that the buckling as input data of UGMG is chosen consistently with the leakage in the stage of criticality calculation. With the resulting constants as input, criticality calculation is carried out by a two-dimensional code “EQUIPOISE-3”. The difference between criticality calculation and experiment proves to be 0.72.2%.
The effect of diffusion constant on neutron flux is examined by intentionally giving different values of this quantity. In view of the considerable effect, it is concluded that the procedures of producing the thermal diffusion constant for the core has to be further investigated. The exponential attenuation constant of fast neutron flux in the reflector has to be incorporated adequately in future in the fast constant preparation.抄録全体を表示PDF形式でダウンロード (823K) -

ジャーナル フリーThe paper considers the recent published data on the phase relations and thermodynamic properties of the ternary uranium oxides. The systems of the major fission products (Rb, Cs, Sr, Ba, Y, La, Ce, Pr, Nd, Sm and Eu) and Na as coolant of FBR and Gd as burnable poison with uranium-oxygen are contained.抄録全体を表示PDF形式でダウンロード (846K) -

ジャーナル フリーThe finite element computer codes are now widely used not only for structural analyses but also for thermal, fluid-dynamical and nuclear-physical problems. In performing calculations with these computer codes, however, it is essential to get a full understanding of their limitations and accuracy of the results.
The finite element method (FEM) computer codes working group under the Research Committee on Nuclear Computer Codes has conducted the benchmark tests for seismic response, inelastic structure and heat transfer problems, in order to study the adequacy of presently-used FEM computer codes and the accuracy of calculations.
This report describes the results and discussions of these benchmark tests.抄録全体を表示PDF形式でダウンロード (888K) -

ジャーナル フリーA method was discussed to lay out monitoring locations for predicting migration of critical radionuclides around a radioactive waste burial site by detecting predictor materials. A case study was done to allocate the monitoring locations around an assumed waste burial site by using 90Sr as a critical radionuclide and 90Y as a predictor material. Possible displacement of monitoring locations with design parameters such as time interval of monitorings is also discussed.
Some instructive results were obtained as follows: (1) The method discussed and proposed in this paper is feasible to get reasonable lay-out of monitoring locations. (2) Time required for detecting a predictor material could be reduced more by the shorter time interval of monitorings. (3) Number of monitoring locations could be reduced more by an analytical technique with lower detection limit.抄録全体を表示PDF形式でダウンロード (6317K) -
