ジャーナル フリーGeneral results obtained from an initial program for developing liquid sodium loop technology and related techniques are reported. The loop systems are outlined, together with operating experi-ences on three types of test loops, i.e., for studies in corrosion and in purification, and a system of mother and daughter loop. A description is given of results obtained on the purification system (cold trap, hot trap, etc.), work undertaken on the loop sodium, and the adopted standard operational procedure. Preliminary results of the corrosion test and carburization test are reported. The main objective of the present experiment was to test austenitic stainless steels, but supplementary work was also done with Cr-Mo steels and refractovy metals (Nb, Ta, Mo, Zr and Ti). Also reported are the methods adopted for analyzing the data, the behavior observed on oxygen, carbon and other impurities in sodium, and work in developing an impurity meter (plugging indicator).抄録全体を表示PDF形式でダウンロード (4475K) -

ジャーナル フリーAn adiabatic calorimeter has been designed for measuring energy absorbed in materials (C, Al, (CH2)n and Pb) placed in the experimental hole of a nuclear reactor.
Details are given of the apparatus and procedures of the calorimeter, followed by an account of the results of calibration and of dosimetry in the TRIGA II type reactor of the Atomic Energy Research Laboratory of the Musashi Institute of Technology, The operating temperatures were 25 ?? -30 ?? at 100kW reactor power, and the energy deposition (or dose) rate was 0.2-2mW/g. The performance has been satisfactory in spite of the poor agreement between the observed and calculated rates of temperature rise. The ratio between energy absorption due to fast neutron scattering and that due to γ-rays obtained in the TRIGA II is consistent with the data obtained with BEPO. The experimental accuracy (standard error) at full reactor power is estimated to be within 2.1%.抄録全体を表示PDF形式でダウンロード (1510K) -

ジャーナル フリーA code was developed for the calculation of external exposure to radioactive cloud from several reactors with different stack heights and release-rates.
Using this code, the resultant exposure rates for 41Ar released from three reactors with assumed release rates were obtained to cover the area in and around the Tokai nuclear site, and iso-pleths were drawn under different wind directions. In the case of NE-wind, mutual superposition of the effects from the three sources must be taken into consideration, while in other cases the effect of each source may be considered independently.
The annual exposure does not exceed 100mR in the populated zones with the release rates assumed in this study.抄録全体を表示PDF形式でダウンロード (399K) -

ジャーナル フリーIn the companion paper(1) the author developed an analytical model for space-dependent boiling water reactor kinetics by method of conventional adiabatic approximation. In this paper some numerical simulations were performed for a sample boiling water reactor of 200MW(th), together with an analysis of its space-time behavior. The external perturbations applied to the reactor were: (1) A step increase in reactivity of 90 cents, (2) sinusoidal variations in reactivity with an amplitude of 10 cents, and (3) sinusoidal variation in vertical acceleration with an amplitude of 0.5g. Results of the simulation study indicate that space-dependence is significant when the reactor is undergoing a large transient, while for small disturbances the reactor behaves with little nuclear space-dependence. The latter fact agrees with experimental results on existing boiling water reactors.抄録全体を表示PDF形式でダウンロード (369K) -

ジャーナル フリーA single-open-end coaxial type Ge(Li) γ-ray detector with an effective volume of 8.7cm3 and a capacitance of 35pF was made by Li-drifting for 440hr at an applied voltage of 140V at 40 ?? in thermomodule-controlled constant-temperature water coolant. The FWHM energy resolution with an E810F preamplifier was 4.2 and 8.0keV for γ-rays of 122 and 1, 173keV respectively. The pulse height distributions of γ-rays from an irradiated natural U sample and 105Rh isotope were measured.抄録全体を表示PDF形式でダウンロード (306K) -

ジャーナル フリーThe propagation of high-frequency disturbances in an infinite plasma is studied by the method of propagators. The plasma is assumed to be an electron fluid with positive uniform background. The propagator is given explicitly in terms of generalized functions. It possesses a characteristic rear wake behind the head of the wave, attributable to dispersion within the plasma.抄録全体を表示PDF形式でダウンロード (574K) -
