It needs long time to carve a molding die of bumper, which has a large and deep cavity. To shorten the milling time, we must make the machining more performable and accurate, and develop the new technology of CAM. In the milling sequence, Primary Roughing, which cut out 90% of the stock, should be more and more performable. So we established Tilt-Plunging and Curve-Fit Spiral Cutting techniques. These techniques will reduce lateral force to the tool, and make remains more small. With the techniques, we reduced both machining and NCdata preparing time to one half. 1 ref., 14 figs.

It is said that the image of ultraprecision improved from 0.1[mu]m to 0.01[mu]m within recent years. Ultraprecision machining is a production technology which forms what is called nanotechnology with ultraprecision measuring and ultraprecision control. Accuracy means average machined sizes close to a required value, namely the deflection errors are small; precision means the scattered errors of machined sizes agree very closely. The errors of machining are related to both of the above errors and ultraprecision means the combined errors are very small. In the present ultraprecision machining, the relative precision to the size of a machined object is said to be in the order of 10[sup -6]. The flatness of silicon wafers is usually less than 0.5[mu]m. It is the fact that the appearance of atomic scale machining is awaited as the limit of ultraprecision machining. The machining of removing and adding atomic units using scanning probe microscopes are expected to reach the limit actually. 2 refs.

Application of ion beam processing to 2-dimensional shapes in the past has been limited to flat shapes or small areas. There is a 3-dimensional plasma-based ion implantation (PBII) technology for which high-density plasma is generated using plural metal ion sources and gas ion sources for the application of pulse voltages. Using this technology, ions are implanted into intricate shapes, large areas, and surfaces of 3-dimensional shapes, and surface reforming is accomplished through thin film formation. It is low in cost and high in productivity, and finds a great demand for use in the fabrication of members of large and complicated engines for automobiles, spacecraft, and aircraft, members of precision machines, and members of electric power facilities and chemical plants where high resistance to abrasion, corrosion, and heat are mandatory. Research and development for its practical application, however, has just started and, before its commercialization, technologies have to be completed involving surface treatment using gas plasma for ion implantation, thin film formation using metal ion plasma, and their hybrid. Similarly important is the technology of generating homogenous plasma. This new technology is expected to enhance economic efficiency, provide means to deal with environmental matters, and improve on energy efficiency. An outline of the proposition for the project is compiled in this report. (NEDO)

Behavior of neural networks relative to noise and the constitution of an optimum network are studied for the construction of a 3-D MT data interpretation system using neural networks. In the study, the relationship is examined between the noise level of educational data and the noise level of the neural network to be constructed. After examination it is found that the neural network is effective in interpreting data whose noise level is the same as that of educational data; it cannot correctly interpret data that it has not met in the educational stage even if such data is free of noise; that the optimum number of neurons in a hidden layer is approximately 40 in a network architecture using the current system; and that the neuron gain function enhances recognition capability when a logistic function is used in the hidden layer and a linear function is used in the output layer. 2 refs., 7 figs., 2 tabs.

Efforts are made for the creation of high melting point metal-base materials to replace the currently-used Ni-base superalloys for the turbine to withstand higher operating temperatures. The main efforts made in fiscal 1997 are outlined. As in fiscal 1996, Nb-base solution alloys, in which solution reinforcement elements such as Mo and W are alloyed, are manufactured by button arc melting and tested for mechanical properties and texture/characteristics. In the designing and evaluation for a strongest Nb-base composite material, Nb-base composite materials are manufactured by use of particle dispersion-strengthening attained by addition of intermetallic compounds or elements to contribute to the formation of oxides, carbides, or nitrides. Nb-base composite materials may also be manufactured by use of eutectic-strengthening attained by utilizing crystallization in the process of coagulation. The resultant Nb-base composite materials are evaluated for their dynamic characteristics at high temperatures. In the development and evaluation of technologies for creating Nb-base materials for high-temperature components, larger specimens as heavy as several kg are tested in line with small specimens for basic studies, and the results are utilized for alloy designing for high-temperature materials. 50 refs., 97 figs., 15 tabs.

This synopsis outlines the Japanese guideline Version 2.0 for the data acquisition protocol of oncology FDG-PET/CT scans that was created by a joint task force of the Japanese Society of Nuclear Medicine Technology, the Japanese Society of Nuclear Medicine and the Japanese Council of PET Imaging, and was published in Kakuigaku-Gijutsu 2013; 33:377-420 in Japanese. The guideline aims at standardizing the PET image quality among PET centers and different PET camera models by providing criteria for the IEC body phantom image quality as well as for the patient PET image quality based on the noise equivalent count (NEC), NEC density and liver signal-to-noise ratio, so that the appropriate scanning parameters can be determined for each PET camera. This Version 2.0 covers issues that were not focused on in Version 1.0, including the accuracy of the standardized uptake value (SUV), effect of body size together with adjustment of scanning duration, and time-of-flight (TOF) reconstruction technique. Version 2.0 also presents data acquired with new PET camera models that were not tested in Version 1.0. Reference values for physical indicators of phantom image quality have been updated as well.

R and D was conducted on a bio-functional material that is formed by synthesizing non-natural amino acids required for the manifestation of the function, incorporating the amino acids into new bio-functional peptides to be synthesized, and fixing the peptides on a substrate such as plastics. Activities were carried out in three areas, which were (1) innovative technologies for producing functional molecules, (2) R and D on materialization technologies of functional molecules: technique of pattern formation by photochemical reaction and of fixation, and technique of preparing peptide film using vacuum thin film forming technology, and (3) comprehensive investigation and adjustment. In (1), migration stimulating activity for microphage was selected as a molecular recognition evaluation system, and on the basis of the structural analysis result of a non-peptide compound/imidazolin compound having migration stimulating activity, molecular structural design was carried out for peptides having migration stimulating activity. The result of the analysis revealed that the spatial arrangement of three phenyl nuclei and the presence of basic structures were important. Among the 22 peptides so designed, only Cbz-Phe-Phe-His-NH{sub 2} showed the migration stimulating activity. For the design, a peptide molecule design system CHARMm/QUANTA/PM3 was used. (NEDO)

The R and D programs were implemented to develop techniques for creating members of high-melting metals, having a very high melting point and potentially excellent high-temperature strength characteristics. These are expected to replace Ni-based superalloys for gas turbine members, to further increase operating temperature of the turbine. The programs were aimed to improve their high-temperature strength and toughness and hence their reliability by microscopically controlling their compositions and structures, and also aimed to improve their durability by coating them with a film capable of preventing oxidation and resisting to gas-induced corrosion to impart resistance to oxidation and corrosion to them. For the design of Nb-based solid solution alloys, it is found that dissolution of Mo at around 30 at.% or less and W at 20 at.% or less in Nb improves their high-temperature strength and toughness. For the design of high-strength Nb-based composite materials, it is found that Si-containing Nb-based composite materials, prepared by mechanical alloying, are amorphous or present in the form of solid solution of Ni supersaturated with Si. The R and D activities were also directed to development of techniques for creating Nb-based superhigh-temperature members, their evaluation, and imparting oxidation resistance to them. (NEDO)

Two kinds of Japanese guidelines for the data acquisition protocol of oncology fluoro-D-glucose-positron emission tomography (FDG-PET)/computed tomography (CT) scans were created by the joint task force of the Japanese Society of Nuclear Medicine Technology (JSNMT) and the Japanese Society of Nuclear Medicine (JSNM), and published in Kakuigaku-Gijutsu 27(5): 425-456, 2007 and 29(2): 195-235, 2009. These guidelines aim to standardize PET image quality among facilities and different PET/CT scanner models. The objective of this study was to develop a personal computer-based performance measurement and image quality processor for the two kinds of Japanese guidelines for oncology (18)F-FDG PET/CT scans. We call this software package the "PET quality control tool" (PETquact). Microsoft Corporation's Windows(™) is used as the operating system for PETquact, which requires 1070×720 image resolution and includes 12 different applications. The accuracy was examined for numerous applications of PETquact. For example, in the sensitivity application, the system sensitivity measurement results were equivalent when comparing two PET sinograms obtained from the PETquact and the report. PETquact is suited for analysis of the two kinds of Japanese guideline, and it shows excellent spec to performance measurements and image quality analysis. PETquact can be used at any facility if the software package is installed on a laptop computer.

Research, development and evaluation were performed with an objective of establishing the basic technology related to three-dimensional circuit elements that integrate functions at ultra-high density. For the basic technology of lamination, the SOI technology suitable for the three-dimensional circuit elements was developed, and it has become possible to manufacture high-quality multi-layered crystalline structure by means of annealing that uses laser and electron beam. In addition, a lateral epitaxial technology for solid phase was developed, and the base to be applied to the three-dimensional circuit elements was established. Furthermore, the technology to put thin film circuits together would be useful for high-density integration in the future. The three-dimensional circuit makes parallel processing in each segment possible, whereas a possibility was shown that the processing can be performed at much higher speed than before. Actually a prototype three-dimensional circuit equipped with functions for parallel processing and judgment processing was fabricated.

In the study of a corrosion resistant high sensitivity gas sensor, the following two technologies are needed: decrease in impurities of materials for super-higher purity, and formation of films with physically high quality such as orientation and homogeneity. Experiments were made on laser excitation separation refining, CVD, laser ablation, super-high vacuum, etc. For the stabilized formation of high-adhesion thin/thick films, studies were carried out of the surface activation for processing substrate surface before film formation, interface counter diffusion in thin film formation process, and the technology for combination of these. The higher-order structure control of materials was attempted using the reaction field combined with the photochemical reaction by the high grade photon field, based on the molecular beam vapor-deposition technology under super-high vacuum. In the synthesis of materials by the photon combined reaction field, studies were made of the design/process of a dynamic device which reacts like pulse the photon/high pressure/strong magnetic field on carbonaceous materials and a static combined reaction field device by the stationary high pressure field. A study was commenced of a synthesis method in relation to fullerene with a new structure which has unique characteristics. (NEDO)

The paper described the FY 1993 results of the technology to create high efficiency power generation use members. A processing method was proposed in which to manifest magnetic characteristics up to the theoretical value level, crystallization of magnetic alloy amorphous was controlled and size/configuration of precipitated micro-fine crystals are made ideal. For the development of environmental purification use high functional catalysts, experiments were conducted on the heightening of purity of materials. Namely, by the two wavelength two stage excitation method using color laser, atomic beams of the material metal emitted by electronic beam evaporating source are photo-excited up near the ionization level. These are separated from the non-ionized components by electrostatic field application, and only the ionized atoms are vapor-deposited on substrate. The separation accuracy was good. Plasma excitation of raw gas was done independently for every component, and the multi-source excitation plasma CVD was proposed which is film-formed on the substrate of which the periphery was separately controlled. The synthesis method was considered of higher-order structure control high functional organic materials which are composed of electrode reaction/high grade photon/extreme magnetic field.

This report summarizes the fiscal 1996 development result on technology for creating advanced bio-affinity materials. The functionally gradient artificial tooth root with fine structure was fabricated by the following processes. The surface of a cylindrical Ti rod was first dry-jet-sprayed with ultrafine particles prepared by RF plasma, where its composition was changed continuously from Ti to alumina in a radial direction to form an FGM layer. The so-formed green composite was then sintered while heating the Ti side and alumina side at 1400K and 1800K, respectively. Compressive strength over 200MPa, durability of 10{sup 7} stress cycles at 1000N, and adhesion strength over 65MPa to substrates were obtained. As the outermost surface of the composite was coated with hydroxyapatite by plasma spraying, cell growth on the surface was confirmed without any contamination with heavy metals. This material is suitable for dental use in mechanical and chemical properties. Study was made on non- destructive analysis of FGM. A slant angle injection method was studied to increase the instrumental resolution power of Rutherford backscattering spectrometers. Composition modification was analyzed at a nm level quantitatively. Positron annihilation Doppler broadening was also measured. (NEDO)

Faults are being actively investigated across Japan since the Great Hanshin-Awaji Earthquake. Discussed in this report is the application of the 3D near-surface reflection seismic survey in big cities. Data from trenching and drilling is used for the geological interpretation of the surroundings of a fault, and the reflection seismic survey is used to identify the position, etc., of the fault. In this article, when the results obtained from the experimental field are examined, it is found that the conventional 2D imaging reflection survey betrays the limit of its capability when the geological structure is complicated, that the 3D reflection seismic survey, on the contrary, is capable of high-precision imaging and, when augmented by drilling, etc., becomes capable of a more detailed interpretation, and that it also contributes effectively to the improvement of local disaster prevention in big cities. Using as the model the Tachikawa fault that runs near JR Tachikawa Station, embodiment of the 3D reflection seismic survey is reviewed. For the acquisition of data excellent in quality in a 3D reflection seismic survey conducted utilizing the roads in the sector chosen for experiment in the urban area, the shock generating points and receiving points should be positioned by taking into account the parameters in the bin arranging process so that the mid-points will be regularly distributed on the surface. 3 refs., 11 figs., 1 tab.

The system was verified with regard to data banking to confirm feasibility of the system to practical application. Among the cloth stabilizing technologies, discussions were given on age-based stability of cloth properties, repetitive transformation resistance, temperature, hardener deposition amount, and bending rigidity in cloths treated with temporary hardening agents. Discoloration, robustness and device damaging effect of cloths were also investigated. A partial and temporary hardening device was fabricated to make partial hardening possible. A continuous deflocculating device was also fabricated making deflocculation of temporarily hardened cloth possible. The deflocculation was discussed on the sewing process in relation with workability, and it was revealed that low-level hardening treatment is effective. It was verified that the handling is facilitated particularly in cloths that tend to curl. (NEDO)

Full Text Available Procjene za prosječan porast morske razine na globalnoj razini do kraja 21. stoljeća najčešće variraju od 0,18 m do ≥ 1 m u odnosu na današnju razinu. Ako se razmatraju procjene koje obuhvaćaju i otapanje grenlandskog i antarktičkog ledenog pokrova, tada se može očekivati porast morske razine od 5 i više m. Sukladno s globalnim promjenama, razina Jadranskog mora također je u porastu. Radi analize potencijalne ugroženosti hrvatske obale od porasta morske razine, izrađena su tri modela porasta razine Jadranskog mora (od 1 m, 3 m i 6 m. Na temelju modela analizira se utjecaj porasta morske razine na različite socioekonomske segmente obalnog prostora. Cilj je istraživanja definirati najugroženije dijelove hrvatske obale. Kako bi se mogli diferencirati najugroženiji dijelovi, izrađen je Indeks ugroženosti obalnih općina ( . U izradi Indeksa koristili su se analizom utjecaja dobiveni kvantitativni podaci o prostornom obuhvatu poplavnih zona te ugroženosti stanovništva i prometne infrastrukture obalne zone. Navedenim su varijablama s pomoću Analitičkog hijerarhijskog procesa (AHP pridruženi različiti težinski koeficijenti, ovisno o važnosti varijable. Pri analizi svih triju modela uočeno je kako se Zadar i njegova okolica ističu kao najugroženije područje hrvatske obale. Zbog toga je na primjeru Zadra izvršena znatno detaljnija analiza mikrolokacijskog utjecaja porasta morske razine. Podaci dobiveni analizom različitih modela pokazuju kako je gotovo cijela hrvatska obala ugrožena, ali i da postoji velik nerazmjer u razini ugroženosti pojedinih dijelova hrvatske obale. Važnost je ovog istraživanja u tome što ono predstavlja temelj za pravovremenu adaptaciju na negativne utjecaje budućeg porasta razine Jadranskog mora.

Research, development and evaluation were performed with an objective of establishing the basic technology related to three-dimensional circuit elements that integrate functions at ultra-high density. For the basic technology of lamination, the SOI technology suitable for the three-dimensional circuit elements was developed, and it has become possible to manufacture high-quality multi-layered crystalline structure by means of annealing that uses laser and electron beam. In addition, a lateral epitaxial technology for solid phase was developed, and the base to be applied to the three-dimensional circuit elements was established. Furthermore, the technology to put thin film circuits together would be useful for high-density integration in the future. The three-dimensional circuit makes parallel processing in each segment possible, whereas a possibility was shown that the processing can be performed at much higher speed than before. Actually a prototype three-dimensional circuit equipped with functions for parallel processing and judgment processing was fabricated. The image pre-processing which has been impossible on the real time basis in the conventional two-dimensional integrated circuit was realized in a speed as fast as milli-second order. These achievements lead to a belief that the targets for the present research and development have been achieved. (NEDO)

In fiscal 1997, study was made on formation of peptides with a biogenic function and molecular recognition function, and peptide materials. The existing automatic design technique of peptides including non-natural amino acids was applied to design of complementary peptides of proteins with known structures to optimize a development technique of ligand. Practical function of peptides as advanced receptor ligand was verified by applying the existing conformation control technique to stable holding of peptide active conformation. Creation of bio-materials, and development of preparation technology of bio-substrates and materializing technology of functional molecular materials were carried out. To construct an electron transfer system by self- organized body of peptides formed on a substrate, a peptide molecular device was prepared and verified using linkers. To use peptides as photoelectron functional molecule, metallized peptide with main helix structure was prepared. The possibility of molecular materials with a fixation function of CO2 was examined. A high-sensitivity bio-sensor was also mentioned. 75 refs., 130 figs., 25 tabs.

Described herein are the results of the FY1993 research and development project, implemented for development of the technologies for modification of material surfaces and interfaces, with the objectives to develop the optimum members for methane-fueled aircraft engines. For R and D of multi-layered films with controlled microscopic structures, the tests are conducted for forming thin-film layers by, e.g., ion implantation, ion mixing and implantation of large quantities of ions as the surface controlling/modification techniques based on, e.g., ionic techniques. The tests are conducted for, e.g., chemical vapor-phase reaction evaporation and low-pressure plasma spraying as the technologies for forming multi-functional films of, e.g., high reliability and resistance to corrosion. For development of the technologies for controlling/compositing the microscopic structures, the tests are conducted for, e.g., selection of the matrix materials, and prevention/removal of defects by the chemical vapor-phase reaction penetration treatment effected for extended periods. For development of the technologies for evaluation of the characteristics under superhigh-temperature environments, the tests are conducted to investigate the mechanical characteristics of isotropically uniform metallic materials under multi-dimensional stresses and evaluation thereof, and mechanical and thermal characteristics of carbon-fiber-reinforced carbon composites and evaluation thereof.

For the creation of new industries and for their expansion to the consumer market, efforts are made to develop laser-aided technology of bonding titanium with other metals and CAD/CAM (computer-aided design/computer-aided manufacture)-aided technology of high-precision multidimensional laser machining for titanium. In the development of technology for bonding titanium and other metals, combinations of titanium and stainless steel and titanium and copper are examined, and a dissimilar metal joint is successfully manufactured, free of cracks at a tension shear strength level of approximately 4200N/40mm and shear stress of 200MPa or higher. In the study of the mechanism of bonding, it is found that a sound weld metal is created with the formation of intermetallic compounds well inhibited by allowing titanium to be on the upper surface. In the study of laser-aided titanium cutting, a dross-free cutting process is realized by optimizing cutting conditions such as those involving laser excitation and assist gas application. Three-dimensional laser-aided cutting is carried out in compliance with a 3-dimensional laser cutting program incorporating metal pattern data, and the process is found to reduce the number of necessary dies to 1/4 to shorten and simplify the process.

Kako se nositi s ekonomskom depresijom: iskustvene i teorijske lekcije Velike depresije

Full Text Available Cilj ovog rada je da ukaže na moguće razloge zbog kojih ne samo da dužnička kriza u evrozoni ne prolazi, već se produbljuje. Mišljenja sam da iskustvo Velike depresije iz tridesetih godina prošlog veka može pomoći ekonomskim teoretičarima i zvaničnicima da sagledaju problem iz druge perspektive, pošto je očigledno da ekonomska ortodoksija i mere ekonomske politike koje se na njoj zasnivaju ne daju željene rezultate. Ruzveltov fiskalni aktivizam i Kejnzova revolucionarna teorija su dali odgovor na pitanje zašto je u periodu krize neophodna odlučna fiskalna reakcija ekonomskih vlasti i zašto slobodno tržište nije u stanju da samostalno izađe iz magle koja vremenom, u slučaju nečinjenja, postaje sve gušća.

This paper describes how to grasp the characteristics of reflected waves which means how the reflected wave can be received in its magnitude depending on the complicated subsurface structure. Data acquisition parameters were also investigated, as to offset distance distribution and mute setting during the HMO correction. A velocity structure model was prepared for an area of 9km{times}8km including the given 3D seismic exploration area at Minami Noshiro, Akita Prefecture. For the geological sequence used for the velocity structure model, three formations, i.e., Katsurane Formation, Funakawa Formation, and Onagawa Formation, were inputted in an order from the shallower depth on the basis of the depth structure profile obtained from the previous data. Ray tracing was calculated by means of the two-dot dashed line tracing method. For this method, amplitude as well as travel time of waves can be calculated at the same time. This was effective for grasping the magnitude of reflected wave on simulating the traced data. For the velocity structure model used in this study, existing data inputted were old, which limited the quantity of information. However, this model would sufficiently contribute to the verification of survey design and the determination of optimal layout. 1 ref., 3 figs.

UPRAVLJANJE ODNOSIMA S POTROŠAČIMA U FUNKCIJI ZADRŽAVANJA POTROŠAČA

Full Text Available Poput mnogi drugih suvremenih pojmova i pojam upravljanja odnosima s potrošačima (CRM u svakodnevnoj praksi izaziva dvojbe vezane za njegovo značenje i njegov obuhvat. Razlog tome treba tražiti u činjenici kako je CRM ujedno i strategija i proces i sustav, stoga je teško jednoznačno definirati pojam koji obuhvaća toliko široko područje. No, prilikom proučavanja CRM-a treba uzeti u obzir kako je to koncept razvijen u okvirima marketing odnosa i poslovne filozofije koja teži zadovoljavanjem individualnih potreba potrošača; potrošača učiniti zadovoljnim i kroz izgradnju sustavne interakcije s potrošačem, potrošača transformirati u klijenta. Kako bi se to uspjelo, potrebno je uspostaviti sustav komunikacije s potrošačem koji će osigurati neposrednu interakciju s potrošačem. Kroz takvu se interakciju potrošač od anonimne jedinke u masi potrošača transformira u individualiziranu i personaliziranu jedinku, o kojoj se sustavno prikupljaju informacije, ali i kojoj se sustavno pružaju informacije. Takav sustav komunikacije, posebice kada je riječ o većem broju potrošača, nije moguće izgraditi bez upotrebe suvremene informacijsko-komunikacijske tehnologije. Zbog toga se CRM sustav integrira u marketing i informacijske sustave, kao i menadžment. Prikupljeni su podatci u točki dodira temelj za kreiranje slike o potrošaču te učinkovito zadovoljavanje njegovih potreba. Takav sustav, također omogućava izbor kvalitetnih potrošača u smislu osiguranja lojalnosti kvalitetnih potrošača. Prema tome CRM omogućava izgradnju defanzivne marketinške strategije koja teži zadržavanju i boljem iskorištenju postojećih potrošača, što u naravi zahtjeva manje napora i sredstava za provedbu od ofanzivne marketinške strategije.

Full Text Available Život počinje mirisom lavande. Moj otac stoji ispred ogledala. Upravo se otuširao i obrijao te se sprema obući odijelo. Gledam ga kako pričvršćuje čvor na kravati, spušta ovratnik košulje i zakopčava najgornji gumb. I onda kao i obično: lavanda.Znam odakle miris dolazi. Na ormariću leži savršeno oblikovana bočica. Jednog dana dok me muči grozna migrena i ležim na kauču u dnevnoj sobi, moja majka, pokušavajući smisliti kako da mi olakša bol, poseže za bočicom, otvara je i kapne par kapi na maramicu koju mi onda stavlja pod nos. Olakšanje je trenutno. Kaže mi da je mogu zadržati. Volim je držati u šaci s glavom lagano zabačenom unatrag, kao da me netko u tučnjavi opalio po nosu koji još krvari – ili kao što sam vidio druge da rade kad su bolesni ili shrvani tugom pa hodaju po kući povremeno udišući s maramice izvlačeći iz sebe zadnji atom snage u očajničkom pokušaju da ostanu na nogama. Volio sam tu maramicu, taj miris koji je dolazio iz njezinih nabora, volio sam je potajno nositi u školu i pod satom kradomice udisati njezin miris koji me vraćao roditeljima, našoj dnevnoj sobi, u svijet koji je bio toliko spokojan da bi samo udisanje tog mirisa oko mene stvorilo zaštitni oblak. Miris lavande značio je da sam zaštićen, sretan, voljen. Miris lavande nosio je sa sobom sretne misli – o životu, o onima koje volim, o meni. Miris lavande izbrisao bi svaku udaljenost i svi bismo bili na okupu u toploj i udobnoj sobi punoj jastuka, pokraj pucketave vatre, a zvuk kiše koji je dopirao izvana podsjećao bi nas kako smo ovdje sigurni. Miris lavande značio je da nas nitko ne može razdvojiti.

This paper describes fault survey by 3D seismic reflection exploration. Survey has been conducted mainly at flat land area without pavement not in urban area in Japan. Subsurface structure is complicated with intersecting multiple faults. In this area, a lot of geological investigations have been done prior to the seismic reflection exploration. Fairly certain images of faults have been obtained. However, there were still unknown structures. Survey was conducted at an area of 170m{times}280m in the CDP range. Measurements were carried out by using 100 g of dynamite per seismic generation point combined with 40 Hz velocity geophones. Fixed distribution consisting of lattice points of 12{times}12 was adopted as an observation method. In and around the lattice, a great number of explosions were carried out. The CDP stacking method and the method of migration after stacking were used for the data processing. The 3D structures of six horizons and five faults could be interpreted. Interpreted horizons were well agreed with the logging results. 3 figs.

Discussed in this report is a wavefield simulation in the 3-dimensional seismic survey. With the level of the object of exploration growing deeper and the object more complicated in structure, the survey method is now turning 3-dimensional. There are several modelling methods for numerical calculation of 3-dimensional wavefields, such as the difference method, pseudospectral method, and the like, all of which demand an exorbitantly large memory and long calculation time, and are costly. Such methods have of late become feasible, however, thanks to the advent of the parallel computer. As compared with the difference method, the pseudospectral method requires a smaller computer memory and shorter computation time, and is more flexible in accepting models. It outputs the result in fullwave just like the difference method, and does not cause wavefield numerical variance. As the computation platform, the parallel computer nCUBE-2S is used. The object domain is divided into the number of the processors, and each of the processors takes care only of its share so that parallel computation as a whole may realize a very high-speed computation. By the use of the pseudospectral method, a 3-dimensional simulation is completed within a tolerable computation time length. 7 refs., 3 figs., 1 tab.

This paper reports pre-stack migration in elastic wave exploration as to its algorithm and examples of processed data. The time migration processing hypothesizes that seismic waves propagate linearly. It calculates travel time by dividing the sum of the straight distance from a vibration transmitting point to an image point and the straight distance from the image point to a vibration receiving point with RMS velocity given as a parameter. To maintain the relative relation of amplitude sizes, the signal on an elliptic body is made smaller in inverse proportion to the size of that elliptic body. With regard to apparent interval of input trace as seen from the reflection surface, or with regard to density, the signal is made smaller by cos{theta} times. While this program deals with three-dimensional migration, its output turns out as an arbitrary two-dimensional plane. The program requires a huge amount of data processing, whereas a method is used, that the input trace is divided, each group is processed by using separate computers, and the results are summed up. 3 refs., 4 figs.

An ultrasonic probe with its point fine is navigated in blood vessels and body cavities by 3-dimensional ultrasonic signals (with the oscillator driven by transmission from a catheter for position detection) for the acquisition of accurate 3-dimensional ultrasound images in a less invasive way. The transmission and reception circuits are provided with circuits for ultrasound tomographic images and for navigation. Trial units are fabricated and tested for transmission waveform and reception performance. The scanner is rotated for the acquisition of intravascular 3-dimensional radial images. The scanner rotating rate is set at 30 rps for the scanner performance not to be affected by heartbeat and the rate is controlled by the observation unit which changes voltage for the control. The 3-dimensional display software program, thanks to the navigation function of the external probe, detects the external probe position relative to the small-diameter probe for the construction of accurate 3-dimensional images. Specifications for a total system, which makes full use of a navigation function, are compiled, consisting of a small-diameter probe and a body surface real-time 3-dimensional display. (NEDO)

Three-dimensional TDEM modeling using finite-difference method; Sabunho ni yoru TDEM ho no sanjigen modeling

Energy Technology Data Exchange (ETDEWEB)

Noguchi, K; Endo, M [Waseda University, Tokyo (Japan). School of Science and Engineering

1997-10-22

Study is made on the theory of three-dimensional modelling of TDEM (Time Domain Electromagnetic) method based on the theory of Wang and Hohmann. A difference scheme is built and investigation is conducted about calculation accuracy with attention paid especially to space and time division, and the obtained optimum value is compared with the analytical solution for a homogeneous medium. As the result, it becomes possible to have a high-accuracy TDEM response thanks to the obtained optimum parameter. In an example, a response is determined in the case of a high-resistivity body in presence near the ground surface. Calculation is performed under the given conditions of a medium 100 ohm/m in resistivity, anomalous bodies 200, 500, 1000, 2000,5000, and 10,000 ohm/m in resistivity, respectively, and a distance in the direction of depth of 20m. The result indicates that it is possible to estimate the effect of the ground surface terrain on a TDEM response. Since the effect of the ground surface terrain emerges at the initial part of a response, it is inferred that consideration of terrain is mandatory in building a model if it is for interpreting the subsurface structure in detail. 5 refs., 7 figs.

Three-dimensional analysis of the magnetic structure in Hokkaido, Japan; Hokkaido no sanjigen jiki kozo kaiseki

Energy Technology Data Exchange (ETDEWEB)

Makino, M [Geological Survey of Japan, Tsukuba (Japan)

1996-10-01

The magnetic structure in Hokkaido was quantitatively analyzed by the magnetic anomaly distribution. This paper describes its characteristics. Detection of structural boundaries and 3-D analysis of double-layer structure were conducted for the regional magnetic data in a region with about 500 km square. There was not so large difference in patterns of magnetic anomaly distribution between the case that the direction of magnetization was set at 45{degree} to the west during the geomagnetic conversion according to Segawa and Oshima and the case that it was set as same as the current geomagnetic direction. The method of Blakely and Simpson was useful to detect the boundaries of magnetic structures. The structural boundaries obtained were more linear than the iso-magnetic contour lines. A new method has been conceived in which the approximation of 3-D magnetic structure analysis can be deduced, and the irregularity of magnetic basement can be determined by the repeated calculation. In practice, this method was applied to the magnetic data in the whole Hokkaido. The calculation was stably converged. It was found that the magnetic structure obtained in the Kamuikotan/Ishikari-Kitakami magnetic belt exhibited a fault structure having steep slopes accompanied by the basin structure in the western boundaries. 19 refs., 6 figs.

The type and applications, manufacturing method, characteristics, road pavement etc. of asphalt were introduced. Among the petroleum asphalts, straight asphalt is used for road pavement,industry, and combustion, while blown asphalt is mainly used for the waterproofness of a building. Also, the demand for modified asphalt where rubber or thermoplastic elastomer was mixed is increasing. Straight asphalt is obtained by allowing atmospheric distillation tower bottom oil to be subjected to reduced pressure distillation and drawing reduced pressure gas oil and lubrication oil cut. Blown asphalt is produced by the oxidation dehydrogeneration and condensation polymerization reaction of soft straight asphalt. Rheology characteristics of asphalt are expressed by stiffness, relaxation elastic modulus, complex elastic modulus, etc. Also, asphalt has high electrical dielectric properties. Asphalt pavement has functions for dispersing traffic load and then transferring it to a lower layer, for resisting wear and cracking, and for preventing penetration of rainwater. 30 refs., 5 figs., 4 tabs.

A large quantity of coolant is used in the grinding process for ensuring high accuracy and quality in the work. This presents a serious problem from the viewpoint of environmental impact or energy conservation, and now environment-conscious grinding methods requiring no or less coolant are sought for. With a view to answering the demand, efforts are exerted to put to practical use, and improve, an EcoloG grinding technique. The goal is to reduce to half the energy that the grinding process is now consuming. The EcoloG technique is a grinding method under which vegetable oil mist is cooled for lubrication and a small amount of cooling water is fed to the point of grinding for removing chips. In fiscal 1999, a survey was conducted on technical literature, patents, and the like in and out of Japan for the study of the actual state of dry machining, and then the course of future studies was clearly established. Studies were also carried out aiming at the practical application and improvement of the EcoloG grinding technique, and the technique achieved a quality level as high as that of the conventional coolant-aided method in a process of grinding a shaft to have an accurate outer diameter by use of an ordinary wheel head.

Three-dimensional modelling methods using the difference method and finite element method are applied to the simulations respectively of the surface electromagnetic method, borehole electromagnetic method, and airborne electromagnetic method, and they are compared with each other in point of accuracy and practicality. The object of calculation in this study is a 3-D model which is a semi-finite medium 100 ohm/m in resistivity that contains a rectangular parallelopiped 1 ohm/m in resistivity. A vertical magnetic dipole is installed on the surface in the surface electromagnetic method, providing a vertical magnetic field on the surface. In the borehole electromagnetic method, a vertical magnetic dipole is placed in a borehole and the resultant vertical magnetic field is measured at a station in another borehole. In the airborne electromagnetic method, the flight level is 20m high and the distance between the source and the receiving point is 10m. The results of calculation all agree well with the results of calculation previously made known. When the difference method and finite element method are compared, it is found that the finite element method requires calculation time and memory capacity two to three times more than the difference method. 5 refs., 9 figs.

Difficult area in this context means an exploration-difficult area supposed to store oil/gas but retarded in exploration for the lack of knowledge about the geological structure due to poor quality of available seismic survey records. Discussed in this paper is a survey conducted into an area covering the southern part of Noshiro-shi, Akita-ken, and Yamamoto-cho, Yamamoto-gun, Akita-ken. An area size suitable for data collection at a target depth of 2500m is determined using an interpretation structure compiled on the basis of available well data and 2D seismic survey data. The plan for siting shock points and receiving points is modified case by case as restrictive factors come to the surface (resulting from the complicated hilly terrain, presence of pipes for agricultural water, etc.). The peculiarities of seismic waves in the terrain are studied through the interpretation of the available well data and 2D seismic survey data for the construction of a 3D velocity model for the confirmation of the appropriateness of the plan for siting shock points and receiving points. Efforts are exerted through enhanced coordination with the contractor to acquire data so that a technologically best design may be won within the limits of the budget. The quality of the data obtained from this experiment is in general better than those obtained from previous experiments, yet many problems remain to be settled in future studies about exploration-difficult areas. 4 refs., 4 figs., 1 tab.

Described herein are results of survey on brown coal liquefaction techniques and peripheral techniques, centered by COSTEAM process under development in USA, solubilization by alcohol and liquefaction and cracking with the aid of tetrahydroquinoline as the hydrogen donor under development in Japan, and low-temperature carbonization and new promising techniques. The COSTEAM process shows higher reaction rates, conversions and oil yields for brown coal liquefaction than the one using hydrogen gas. Some of the problems involved in this process high viscosity and oxygenated compound content of the product oil. The product oil is acceptable as fuel for power generating plants and can be produced at a moderate cost, but may be unsuitable as vehicle fuel. Coal liquefaction and solubilization processes are mainly represented by those which use hydrogen. The hydrogen cost, which is high, determines the product price. The processes which use alcohol or tetrahydroquinoline are still in the experimental stage. (NEDO)

Processed foods must be produced in mass, cheap and safe and should be suitable for the delicate taste of human being. Food tastes are effected by an outlook on human attitude, and the surrounding environment. And these factors are reflected to unit operation in food manufacturing and processing and it is clarified that there are many technical difficulties. The characteristics of unit operation for food manufacturing and processing are that the food materials are a multicomponent system, moreover, a very small amount of aroma components, taste components, vitamin, physiologically activation materials and so on are more important than the main components, and also inapplicable of the model centering to the most quantitative component. The purpose of unit operation in food manufacturing and processing is to produce the properties of matter matching to human sense, and therefore there are many problems left unsolved. The development of analytical technology also has an influence on manufacturing and processing technology. Consequently, food manufacturing and processing technology must be based on general science. It is necessary to develop unit operation with an understanding of mutual effect between food and human body.

A wind-resistant design of cables for large cable-stayed bridges is required as a measure against rain-wind induced vibration. In such bridges, many cables are arranged in a short pitch, which causes a large drag force on the cables. Therefore, reduction of drag force on cables is essential for rationalizing bridge design, as well as restraint of vibration. This paper describes studies on a new cable having both a low drag co-efficient force and rain-vibration suppressing effects. Through many investigations using wind tunnel tests, an indented cable was developed as a countermeasure against rain-wind induced vibration, and finally it was applied to the Tatara Bridge which is the largest cable-stayed bridge in the world.

As a realistic measure to reduce environmental pollutants emitted from coal-fueled boilers, a developmental study was conducted of high-efficient combustion systems. In fiscal 1994, four types of topping cycles which are different in system structure and gasifier type were selected, and topping cycles assuming a 300MW-class power plant were trially designed. Further, an evaluation of adaptability of these systems was made, and an selection of the optimum system for the early development was made among the systems. As a result, the evaluation was obtained that `a system using air blown gasifier` is most suitable for conducting the next-stage research. In the element test on the topping combustion technology, collection was made of data of desulfurization activity, desulfurization oxidation mechanism and alkali metal behavior at the laboratory level, data of temperatures and gas concentration distribution in coal gasification, data of simulation of the gasifier reaction, and the other data. 262 figs., 66 tabs.

Introduced herein is a reflection wave velocity analysis method using model scanning as a method for velocity estimation across a section, the estimation being useful in the construction of a velocity structure model in seismic exploration. In this method, a stripping type analysis is carried out, wherein optimum structure parameters are determined for reflection waves one after the other beginning with those from shallower parts. During this process, the velocity structures previously determined for the shallower parts are fixed and only the lowest of the layers undergoing analysis at the time is subjected to model scanning. To consider the bending of ray paths at each velocity boundaries involving shallower parts, the ray path tracing method is utilized for the calculation of the reflection travel time curve for the reflection surface being analyzed. Out of the reflection wave travel time curves calculated using various velocity structure models, one that suits best the actual reflection travel time is detected. The degree of matching between the calculated result and actual result is measured by use of data semblance in a time window provided centering about the calculated reflective wave travel time. The structure parameter is estimated on the basis of conditions for the maximum semblance. 1 ref., 4 figs.

A study was made about integral equation-assisted numerical calculation in a time domain electromagnetic (TDEM) 3D modeling. The total number of cells should be minimized now that the time required for calculation depends a great deal upon the total number of cells. On the assumption of a thin plate-like layer of anomaly in presence, with its center positioned just below the receiving point and with its entirety buried in a homogeneous 100 Ohm m medium, the correlation between the distance and the maximum cell length in the horizontal direction and the method of dividing were examined. As the result, it was found that a dividing method respecting the exponential function shortens the calculation time and that, for obtaining a true response and for minimizing the calculation time, the length of the horizontal side of the cell nearest to the transmission source needs be set to be not more than 1/2 of the distance. It was also found that the length of the side in the direction of depth of the topmost cell needs be set to be not more than approximately 1/3 of the depth of the upper surface of the plate-shaped anomaly. 2 refs., 10 figs., 2 tabs

A slamming load generated by interactive motions between a ship body and water face is an important load in ensuring safety of the ship. A flat plate approximation developed by Wagner is used as a two-dimensional slamming theory, but it has a drawback in handling edges of a flat plate. Therefore, an attempt was made to expand the two-dimensional Wagner`s theory to three dimensions. This paper first shows a method to calculate water face slamming of an arbitrary axisymmetric body by using circular plate approximation. The paper then proposes a method to calculate slamming pressure distribution and slamming force for the case when shape of the water contacting surface may be approximated by an elliptic shape. Expansion to the three dimensions made clear to some extent the characteristics of the three-dimensional slamming. In the case of two dimensions or a circular column for example, the water contacting area increases rapidly in the initial stage generating large slamming force. However, in the case of three dimensions, since the water contacting area expands longitudinally and laterally, the slamming force tends to increase gradually. Maximum slamming pressure was found proportional to square of moving velocity in a water contacting boundary in the case of three dimensions, and similar to stagnation pressure on a gliding plate. 12 refs., 17 figs., 1 tab.

Research and development has been made with an objective to replace the electric discharge processing consuming a large amount of energy and having environmental load, with the cutting process consuming less energy while maintaining the equivalent processing precision. This paper summarizes the achievements in fiscal 2000. Development of cutting tools has made three times or more as many multi-aspect utilization as compared to conventional tools possible by researching the tip shapes. In addition, ultra hard end mill suitable for cutting very hard materials using an ultrasonic cutting head was fabricated on the trial basis, and its cutting capability was verified. In developing the cutting processing heard, a vibration mode possible of cutting with the ultra hard tool was generated, ATC has become possible, and the possibility of cutting hard-to-cut materials was verified. For processing a narrow and deep part, an improved type tool was developed, whereas the practical cutting performance suppressing wear of the blade tip was obtained. To deal with the environment, development and prototype fabrication were performed on a unit having a grease lubricated high-speed main shaft that is considered to be the mainstream in the future. In the operation test at 20,000 min-L, know-how was acquired in relation with the basic performance, manufacture and use of the unit. (NEDO)

For 3-D magnetotelluric (MT) modeling, spectral Lanczos decomposition method (SLDM) was applied as high-speed high- accuracy modeling algorithm. SLDM was developed by Druskin to reduce computational time considerably by obtaining responses in the whole frequency domain all at once. The computational time of 3-D modeling was reduced by introducing Maxwell`s equation and Lanczos matrix as transformation matrix. The computation was carried out on the 1km{times}2km{times}2km low resistivity model body of 5 ohm{center_dot}m supposed in the uniform ground of 100 ohm{center_dot}m using 43{times}43{times}31 nodes at 17 frequencies ranging from 0.01Hz to 100Hz. Apparent resistivity at lower frequency decreased with approach to the low resistivity body. The computational time amounted to 6 hours 14 minutes. The 3-D MT modeling using SLDM method was independent of frequency, and its algorithm was superior in computational speed, however, it was inferior in computational time as the number of measuring nodes increased. 2 refs., 3 figs.

The R and D were conducted of a grinding machine system of an environmental-friendly type in which no coolant is used or the amount of coolant is reduced, and the FY 2000 results were summed up. As to the ECOLOG grinding newly thought up, the roles were divided: the lubrication into a trace of the vegetable oil supplied onto the grindstone surface, cooling into a trace of the cooling water supplied to the structure, discharge of chips to the cooling water for bed table cleaning. By this, the amount of the cooling water becomes approximately 1/3 of that in the conventional grinding. Concerning the ECOLOG grinding using the usual grindstone, the grinding performance equal to that in the conventional grinding was confirmed. In the study for making the cooling water non-pollutant, the chlorine/sulfur free coolant was developed which includes no chemical substances designated by the PRTR law at all. It was confirmed that the grinding performance was almost the same level as the existing coolant which includes sulfur. In the study of the supply of coolant applied with ultrasonic waves, the result was obtained that in the optical glass grinding, the number of scratches decreased and the surface roughness improved even at the flow rate of coolant which is less than in the conventional grinding.

The number of road traffic victims in Japan has been above the level of 10,000 annually during 8 consecutive years, but in 1996 and 1997, it becomes below this level. The casualty of road traffic accidents is found to be occurred during driving and senior persons account for a large part among victims while 55.1% of the case took place at night. As for the countermeasures, it is possible to indicate the regulatory strengthening, advancement of accident investigation and analysis, provision of safety information to the user and research and development of advanced safety vehicle (ASV). Concerning preventive safety, studies on the human recognition, systems for assisting judgement and running and so on can be enumerated. The ASV is in the course of 2nd program that lasts until 2001 with 6 safety research subjects such as prevention, collision, automatic operation, containment of disaster from expanding and so forth. In terms of post-accident safety, remarkable research and development have been conducted on collision by means of dummy and human body, human resistance against injury, air bag for rider protection and child seat, and especially the form comparison of interior materials for head protection apparatus as well as study via simulation, together with commercialization of side bag for reducing head damages. As for car body materials, energy absorption by pillar type elements, use of aluminum materials, resistance comparison and design concept of structural separation and so on are being carried out. 69 refs., 1 fig.

This paper describes attempts of establishing an oil recovery technology utilizing microorganisms and of aiming at improving the practicability of that technology. Fiscal 1994 has investigated effects of inorganic salts existing in reservoir beds and NaCl concentrations on proliferation of microorganisms and production of metabolites. The investigation was intended to discuss applicability of microorganisms to environments that are brought closer to actual field conditions. Furthermore, a core sweeping test using sandstone was carried out on the fiscal 1992 separated bacteria, the 4118 bacteria, that has high surfactant production capability. In addition, a sand pack was used to perform a flooding experiment under conditions of 50{degree}C and 50 KSC to evaluate functionality of microorganisms when environments in the reservoir bed are simulated with respect to pressures and temperatures. An oil recovering experiment was carried out using a sandstone with a diameter of 1.5 inches, a length of 1.0 foot and permeability of 600 md, and using Bacillus subtilis 4118 bacteria which attained the lowest interfacial tension among the bacteria examined. A recovery rate of 4.4% Sor was derived in the experiment. A recovery rate of 29.0% Sor at maximum was obtained when Bacillus licheniformis 18-2-a bacteria was supplied into a sand pack filled with silica sand. 20 figs., 7 tabs.

This paper reviews the current status from the standpoint of chemical engineers facing the coming of the 21st century, and surveys the paradigm for new scientific technologies. The criticism is mixed with unique opinions everywhere, such as `departure of students from scientific and engineering faculties is none other than the result of a market principle`, `national burden of trillions of yens should not be spent only under a justice of advancement of the science`, and `the global civilization itself has no other way but to change from the conventional expansive development type of the western country style to the internal development type of the oriental country style`. Values that define the paradigm for new scientific technologies may include such keywords as saturation in technology, baseless expansion of research projects, criticism on science, market principle, and centering human being. It should be looked at seriously that profit from research and development should exceed the cast invested therein in the future, and scientific technologies that serve truly the society should be aimed at. These efforts will result in one of the large pillars that support the future in which creation of new functions is aimed at as a result of structuring the new systems. Trying to overcome the environmental problems is one of them.

This survey was conducted to construct the core of intelligent social infrastructure technology (ISIT), and to investigate its practical application to industries and society. For realizing the ultra-safe and ultra-reliable society, it is necessary to develop the ISIT which can integrate various social infrastructures, such as architecture, city, energy, and lifeline systems required for living. For the systematization of cities, it is necessary to process and control the intelligent information by holding integrated and transverse information in common, as to logistics, lifeline, communication, monitoring, and control. For the communication engineering, the centralized systems are acceleratingly to be converted into the distributed network systems. For the mechanical engineering, intelligent control and robot technology are required. For the architectural engineering, a concept exceeding the conventional antiseismic structure idea is investigated. It is necessary to develop a new information technology providing an intelligent social infrastructures by merging the information networks and the physical world seamlessly. Necessity of ISIT is large for constructing the intelligent and ultra-reliable society consisting of these integrated and organized networks. 84 refs., 68 figs., 6 tabs.

From the sonic prospecting on the ground, it was confirmed that faults distributed in the inner part of Suruga Bay extend near the Fujigawa river mouth. While, faults in the sea bottom were found by the sonic prospecting using a single air-gun. However, continuity of faults running from the land to the sea has not been reported. This paper describes the continuity of Fujigawa fault system running from the land to the sea around Fujigawa river mouth along the subduction zone of Philippine Sea Plate using single air-gun seismic reflection records. Locations of the faults can be expressed as fracture information of linearment obtained from the satellite remote sensing images, which agreed well with those found by the Active Fault Research Association. As a result of the image processing, they agreed distinctly with the topography of Fujigawa fault system. Thus, much more accurate analysis can be performed by comparing the regional information by the remote sensing with the sonic seismic reflection profiles. 3 refs., 2 figs.

Discussions were given on a method to suppress coherent noise in data derived from a non-uniform vibration transmitting-receiving point layout in three-dimensional seismic exploration. The discussions attempted suppression of coherent noise by utilizing a prediction filter for the frequency-space zone. The prediction filter for the frequency-space zone is a filter which handles coherent waveforms found in the record as a signal, and attenuates random noise. Methods to remove coherent noise may include paralleling of signals, making the tracing order random, use of an FX prediction filter, restoration of the tracing order, and restoration of the signal positions. As a result of the discussion using a simple model, it was made clear that coherent noise distributed spatially can be suppressed and signals can be extracted by applying the frequency-space zone filter. In addition, the signals extracted by this operation were found to maintain well the original waveforms. 7 refs., 9 figs.

For improving the quality of data collected by reflection seismic exploration, a lattice was deployed at one point of a traverse line, and the data therefrom were used to study the 3D coherent noise suppression effect of the areal array. The test was conducted at a Japan National Oil Corporation test field in Kashiwazaki City, Niigata Prefecture. The deployed lattice had 144 vibration receiving points arrayed at intervals of 8m composing an areal array, and 187 vibration generating points arrayed at intervals of 20m extending over 6.5km. Data was collected at the vibration receiving points in the lattice, each point acting independently from the others, and processed for the composition of a large areal array, with the said data from plural vibration receiving points added up therein. As the result of analysis of the records covering the data collected at the receiving points in the lattice, it is noted that an enlarged areal array leads to a higher S/N ratio and that different reflection waves are emphasized when the array direction is changed. 1 ref., 6 figs.

The 3-D model program was developed to apply a mise-a-la-masse method to linear current sources with optional shapes. Mise-a-la-masse method is a bipolar mapping survey method using current sources installed in wells, and recently has been widely used for direct exploration of geothermal reservoirs. This method is also used for monitoring underground fluid as electrode arrangement of fluid flow tomography for surveying underground fluid (geothermal fluid, underground water, petroleum). In the geothermal reservoir exploration, the casing pipes of wells are used as linear current sources, and measured data are processed as those based on vertical current source. In the largely inclined well, the inclination of current sources should be considered. The 3-D modeling program was developed by difference calculus using the theoretical potential equation and apparent resistivity based on linear current sources with optional 3-D shapes. The numerical model experiment result clarified that the previous theoretical equation for vertical wells is inapplicable to inclined linear current sources because of clear asymmetric apparent resistivity distribution. 6 refs., 6 figs.

Based on the uranium microstructure in the fuel element, i.e. grain size, presence of other phases, porosity and the position of metal connections, some data could be obtained about the mechanical and thermal treatment of the uranium during fuel element fabrication. The mentioned characteristics could indicate the behaviour of the fuel under reactor operating conditions taking into account its stable dimensions and roughness of its surfaces. Na osnovu mikrostrukture urana u gorivnom elementu, odnosno velicine i oblika njegovih kristalnih zrna, prisustva drugih faza, pozoziteta kao i rasporeda metalnih ukljucaka, mogu se dobiti izvesni podaci o tome koje je postupke mehanickog i termickog tretiranja pretrpeo uran u pripremi za gorivni elemenat. Prethodne karakteristike takodje mogu da daju predstavu o tome kako ce se gorivo ponasati u uslovima rada reaktora, s obzirom na njegovu dimenzionu stabilnost i ogrubljivanje njegove povrsine (author)

Dejavniki, ki sodobne turiste spodbujajo k obisku narodnih parkov, pogosto niso jasni. Sodobne družboslovne raziskave se jim ne posvečajo dovolj. Zato smo preučili profil in potrebe urbanih obiskovalcev narodnega parka Pelister v Republiki Makedoniji. Zanimalo nas je, v kolikšni meri je njihovo zanimanje za naravne značilnosti območja pristno oziroma površno in simbolno. Izsledki so pokazali, da je zanimanje urbanih obiskovalcev predvsem površno. To razkriva potrebo po razvoju učinkovite strategije za odnos do obiskovalcev, ki bo sestavni del splošnega upravljanja narodnih parkov.

zahvat, koji se odnosi na zamenu celokupne instrumentacije je u toku, ali njegova realizacija u 1991. godini kasni zbog zastoja u isporuci opreme koja se izradjuje u Sovjetskom savezu. Izradu ove opreme finansira Medjunarodna agencija za atomsku energiju kroz ugovor sklopljen decembra 1988. godine sa moskovskom firmom Atomenergoexport. Prema tom ugovoru trebalo je da celokupna nova instrumentacija za reaktor RA bude isporucena Institutu u Vinci do kraja 1990. godine, ali je do septembra 1991. godine isporuceno svega 56% od predvidjene kolicine. Od tada je svaka isporuka obustavljena, a razlog je privremena zabrana na sve isporuke opreme za Jugoslaviju izrecena od strane ove organizacije Ujedinjenih nacija. U 1991. godini na reaktoru RA je demontirana postojeca instrumentacija u maksimalno mogucem obimu, kako bi se zadrzala neka osnovna merenja neophodna i u uslovima kada reaktor nije u pogonu. Pri kraju je izrada odredjenih konstrukcionih elemenata za novu instrumentaciju, koju je prihvatio da realizuje Institut u Vinci, kako bi se ubrzala realizacija ovog projekta. Ako sva predvijena oprema ne bude isporucena do kraja marta 1992. godine, nece moci da se otpocne sa probnim radom reaktora u prvoj polovini 1993. godine, kako je planirano. Na realizaciji projekta u 1991. godini ucestvovalo je efektivno 53 radnika, sto je dovoljan broj u uslovima remontnih i investicionih radova. Godisnji izvestaj o radu nuklearnog reaktora RA za 1992. godinu sastoji se od dva dela: prvi deo obuhvata pogon i odzavanje reaktora RA, a drugi poslove zastite od zracenja na reaktoru RA.

This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a steel technology field. Japanese steel industry should correspond to requirements of the international economic society as the top runner. Although it is now difficult to suppose a basic technology innovation, stable supply of basic materials is necessary for peripheral industries. The basic raw material technology is the basis of domestic and overseas socio- economic activities. The technology development support system to retain the world-wide leadership of Japanese industries is a strategic issue. Preparation of cooperative R and D bases of industry, academia and government along a national policy is important. Strong promotion of such national projects is also essential as global environment problem, positive use of advanced information tools, development of technologies and products of unexplored fields, and development of new products and demand creation according to social needs. Such measures along social requirements are also important as raw material development to double an energy efficiency, and the policy and system to construct a recycling society and living spaces.

Research and development have been carried out on a high-level water purifying system using ozone and activated charcoals to supply drinking water free of carcinogenic matters and odors. This system comprises a system to utilize ozone by using silent discharge and oxygen enriching device, and a living organism/activated charcoal treatment system. The latter system utilizes living organisms deposited on activated charcoal surfaces to remove polluting substances including ammonia. The treatment experimenting equipment comprises an ozone generating system, an ozone treating column, an activated charcoal treating column, an ozone/activated charcoal control device, and a water amount and quality measuring system. An experiment was carried out using an experimental plant with a capacity of 20 m[sup 3]/day on water taken from the sedimentation process at an actual water purifying plant. As a result, trihalomethane formation potential was removed at about 40% in the ozone treatment, and at 70% in the whole treatment combining the ozone and living organism/activated charcoal treatments. For parameterization of palatability of water, a method is being studied that utilizes nuclear magnetic resonance to investigate degrees of water cluster. The method is regarded promising. 1 ref., 4 figs.

Sludge generating in a sewage treatment plant is disposed through the processes such as concentration, dehydration, and incineration in sludge disposal facilities. In recent years, there has been a trend that this sludge increases in volume as well as worsens in the concentration. A case is predictable where the sludge load to the dehydrating process is so large that the sludge can no longer be processed in sufficient quantity. In the meantime, if sludge is ozone-treated, viscous substance on the surface of sludge particles can be separated with a comparatively small amount of ozone, with sludge concentration enhanced. At Meidensha, an experimental plant was set up for the ozone treatment of sludge in a sludge intensive treatment plant of a metropolis, with a verification experiment carried out for a sludge concentration improving system by ozone. As a result of comparison of the treatment performance between an assessment system for performing ozone treatment and a reference system for not performing, the average value of the sludge concentration of a gravity concentration tank was 1.9% of the reference system against 1.7% of the assessment system in a continuous treatment experiment in the summer, while the solid collection ratio was 65.8% of the reference system against 95.5% of the assessment system, enabling a superior improving effect to be obtained.

Modern apparel industries are required to supply many kinds of products corresponding to various needs of consumers. Among consumers' needs, comfortableness to wear such as size-fitness is primarily important. To facilitate apparel industries, it is expected to develop a new technology of pattern designing of comfortable garment and measuring garment pressure distribution. Our research is aimed at developing technology that uses computer simulation to predict and evaluate wear comfort, including size suitability, without the need to actually sew up a garment. First, we developed a basic system to predict wearing silhouette, garment pressure, and ease looseness of the garment. Using this system, we carried on the following study. The 3-dimensional distributions of the garment pressure and ease looseness were reversely mapped on the paper pattern in order to indicate the preferable modification. The system was extended for several poses, e.g. twist, bend. From various parameters, we examined the factors of garment pressure and ease looseness. In addition, we selected the parameters for the size-fit indicators and investigated size-fit evaluation indicators. (author)

The paper described the results of the survey of the fine ceramics technology field relating to the FY 1999 long-term energy technology strategy. The fine ceramics industry is a new industry for which the future development is expected. It has far-reaching effects on other industries. Japan has the advantage over other countries. As subjects to remarkably develop the industry, needed are the long-term basic preparation which promotes technology innovation such as the promotion of the fundamental/creative R and D, construction of an industry/university liaison system, and arrangement of the intellectual base. Preparation of the competitive environment and promotion of policies paying attention to the market are needed which make the development under the private control by creative study/corporate activities possible. Also important are the demonstration of leadership and secure international competitive force in the light of Japan's international position. For the private-control development, the role and course of various groups should be made clear from a long-term aspect. It is desirable that university/government will newly develop innovative technology, and industry will make the present technology force more developmental and competitive. Support from the nation is requested for researches large in scale. (NEDO)

1983-01-01

Fresh water, 100 l each, was collected, and to which the carriers of strontium and cesium were added immediately after the sampling. The sample was vigorously stirred and filtered, and passed through a cation exchange column. Strontium and cesium were eluted with hydrochloric acid from the cation exchange column. The eluate was used for radiochemical analysis. The chemical separation of strontium-90 and cesium-137 was carried out, and the chemical yields were determined. The precipitates were counted for the activity using low background beta counters normally for 60 min. The net sample counting rate was corrected for the counter efficiency, recovery, self-absorption and decay, to obtain the radioactivity per sample aliquot, and the concentrations of these nuclides in the original samples were calculated. The data at six sampling locations in Japan from September to December, 1983, on fresh water are reported. (Kako, I.)

In order to carry out the structural design of high temperature pipings, intermediate heat exchangers and isolating valves for a multipurpose high temperature gas-cooled reactor, in which coolant temperature reaches 1000 deg C, the creep characteristics of Hastelloy X used as the heat resistant material must be clarified. In addition to usual creep rupture life and the time to reach a specified creep strain, the dependence of creep strain curves on time, temperature and stress must be determined and expressed with equations. Therefore, using the creep data of Hastelloy X given in the literatures, the creep constitutive equation was made. Since the creep strain curves under the same test condition were different according to heats, the sensitivity analysis of the creep constitutive equation was performed. The form of the creep constitutive equation was determined to be Garofalo type. The result of the sensitivity analysis is reported. (Kako, I.)

Attention is paid to reduction in area required for solar cells by solar concentration as a means of solving cost limits of solar cells and unstable supply of Si materials. Low concentration solar cells are effective from the aspects of utilization of scattered light and unnecessary ray tracing. The optical concentration ratio was calculated of three-dimensional lens having design values of various north/south and east/west direction allowable incidence half angles. The three-dimensional lens are designed by cutting a rectangular parallelepiped by the two-dimensional composite elliptical plane designed by various allowable incidence half angles from two directions of north/south and east/west. Using Perez`s sky solar radiation models and meteorological data HASP, calculated were the annual accumulated global radiation ratio on an inclined surface and the optical efficiency. Calculated were the solar cell area ratio and solar concentration area ratio of the concentration type to obtain solar radiation the same as that of the planar type. From the optimization calculation, it was found that lens are optimal which have design values of north/south and east/west direction allowable incidence half angles of 30-70deg. The solar cell area ratio is 57% and the solar concentration area ratio is 1.2 times. It was found that by making the module area 1.2 times, more than 40% of the solar cells used can be saved. 5 refs., 8 figs.

This report summarizes the fiscal 1999 basic research result on industrial technology strategy of an aircraft technology field. In an aircraft field, since the major theme is application of new technologies to new airframe development, with joining in international cooperative development of aircraft, Japanese initiative development of airframes based on the domestic market demands and profitability should be started as early as possible. Because there is no airframe development by only one country including U.S.A., Japan is profitable to unite with some overseas companies, and invest selectively in specific leading fields. Positive technical support to safety, reliability, comfort and environment harmony are also important. More important theme than establishment of elementary technologies is preparation of an integrated flight demonstration system to expand application chances of development results, and preparation of various test facilities for tests required during development activities. Application of information technologies to the whole aircraft industry, and organic cooperation between the private and public sectors are also important. (NEDO)

1980-01-01

Study was made on a helium turbo-expander, the heart of helium refrigerator systems, in order to develop a system which satisfies the required conditions. A helium turbo-expander with externally pressurized helium gas bearings at the temperature of liquid nitrogen and an alternator as a brake have been employed. The essential difference between a helium turbo-expander and a nitrogen turbo-expander was clarified. The gas bearing lubricated with nitrogen at room temperature and the gas bearing lubricated with helium at low temperature were tested. The flow rate of helium in a helium refrigerator for a large superconducting magnet is comparatively small, therefore a helium turbine must be small, but the standard for large turbine design can be applied to such small turbine. Using the alternator as a brake, the turbo-expander was easily controllable electrically. The prototype turbo-expander was made, and the liquefaction test with it and MHD power generation test were carried out. (Kako, I.)

Recently, in order to meet the difference of electric power demand owing to electric power situation, large scale load following operation has become necessary. Therefore, the development of the cladding tubes which withstand power variation has been carried out, as the result, zirconium-lined zircaloy 2 cladding tubes have been developed. In order to reduce the sensitivity to stress corrosion cracking, these zirconium-lined cladding tubes require uniform liner thickness over the whole surface and whole length. Kobe Steel Ltd. developed the nondestructive liner thickness measuring technique based on ultrasonic flaw detection technique and eddy current flaw detection technique. These equipments were applied to the manufacturing and inspection processes of the zirconium-lined cladding tubes, and have demonstrated superiority in the control and assurance of the liner thickness of products. Zirconium-lined cladding tubes, the development of the measuring technique for guaranteeing the uniform liner thickness and the liner thickness control in the manufacturing and inspection processes are described.

In the past, the construction works of almost all reactor buildings were carried out by big five companies, but as the number of joint venture projects increased, the way opened for submajor firms to participate in the construction of main nuclear buildings. When the five major companies alone engaged in the construction of nuclear plant buildings, three submajor firms did most of the civil engineering works needed. The civil engineering works have been carried out also as joint venture. In order to break through the big five barrier, submajor companies have been engaged in the independent and joint development of nuclear-related design and construction techniques, and the gap with major companies has been closing. The typical joint study done by seven submajor companies was on the load-deflection characteristics of building structures. Also they engaged in aseismatic studies. The method of stripping the contaminated surface layer of shielding concrete is a new technique studied by JAERI. The activities of eleven submajor companies are reported. (Kako, I.)

Influence of pseudo-random geometry on the imaging for 3D seismic exploration data acquisition has been investigate using a simple model by comparing with the regular geometry. When constituting wave front by the interference of elemental waves, pseudo-random geometry data did not always provide good results. In the case of a point diffractor, the imaging operation, where the constituted wave front was returned to the point diffractor by the interference of elemental waves for the spatial alias records, did not always give clear images. In the case of multi point diffractor, good images were obtained with less noise generation in spite of alias records. There are a lot of diffractors in the actual geological structures, which corresponds to the case of multi point diffractors. Finally, better images could be obtained by inputting records acquired using the pseudo-random geometry rather than by inputting spatial alias records acquired using the regular geometry. 7 refs., 6 figs.

Performance of a Wells turbine was improved by equipping 3D guide vanes before and behind a rotor. For further improvement, 3D guide vanes have been proposed in this paper. The performance of the Wells turbine with 2D and 3D guide vanes have been investigated experimentally by model testing under steady flow conditions. Then, the running and starting characteristics in irregular ocean waves have been obtained by a computer simulation. As a result, it is found that both of the running and starting characteristics of the Wells turbine with 3D guide vanes are superior to those of the turbine with 2D guide vanes. (author)

As the surroundings of objects of oil exploration grow more complicated, seismic survey methods have turned 3-dimensional and, in this report, several models are examined using the 3-dimensional simulation technology. The result obtained by the conventional wave tracking method is different from actual wavefields, and is unrealistic. The difference method among the fullwave modelling methods demands an exorbitantly long computation time and high cost. A pseudospectral method has been developed which is superior to the difference method, and has been put to practical use thanks to the advent of parallel computers. It is found that a 3-dimensional survey is mandatory in describing faults. After examining the SEG/EAGE Salt model, it is learned that the salt is well-developed and that 3-dimensional depth migration is required for sub-salt exploration. It is also found through simulation of the EAGE/S Overthrust model, which is an elastic model, that no quality records are available on thrust zones in complicated terrains. The records are poor in quality since the actually measured wavefield is regarded as an acoustic wavefield when it is an elastic wavefield. 1 refs., 18 figs., 2 tabs.

In order to predict the three-dimensional response to vortex-induced oscillation of bridges, a model was investigated using the aerodynamic force coefficient including vortex-induced and self-excited forces, and the nonlinear response coefficient expressing constancy of response to vortex-induced oscillation. In the analysis, change of frequency in wind by the self-excited force, aerodynamic damping term, effect of the mode, and correlation of the vortex-induced force along member axis were taken into account. The aerodynamic force and nonlinear response coefficients were identified from the homogeneous and turbulent flow results of wind tunnel tests using a two-dimensional spring support rigid body model with varied damping factor. The aerodynamic damping term can be estimated from the nonlinear aerodynamic force coefficient, but it was enough to calculate it from the quasi-stationary coefficient in general bridge profiles. The correlation of the vortex-induced force was obtained from measurements of the vertical variation components of trailing flow under the resonance state, or the pressure distribution of the member surface. When comparing to the wind tunnel test of three-dimensional model of cable-stayed bridge, the response amplitude by the present analysis method was consistent well with the test results rather than by the method in which the amplitude of two-dimensional model was corrected. 10 refs., 4 figs., 3 tabs.

Remarkable progress has been made in superconducting technology recently. This paper describes the details and technical features of every cooling type of practical superconducting magnet (SCM), including the SCM for magnetic resonance imaging (MRI), SCM for semiconductor pulling devices, high-field SCM, SCM for magnetically confined plasma devices, and SCM for particle detectors. Commercial production of pool-boil-cooled SCMs has been realized by reducing helium evaporation and decreasing the frequency of helium pouring. The development of forced-cooled SCMs has made it possible to build large SCMs. Moreover, the development of the 4 K-GM refrigerator has enabled liquid-helium-free SCMs to be introduced. Since this type of SCM can be operated merely by turning on a switch, SCMs are expected to come into more widespread use. 7 refs., 1 fig.

For the application of photon to industrial technologies, in particular, a hard photon technology was surveyed which uses photon beams of 0.1-200nm in wavelength. Its features such as selective atom reaction, dense inner shell excitation and spacial high resolution by quantum energy are expected to provide innovative techniques for various field such as fine machining, material synthesis and advanced inspection technology. This wavelength region has been hardly utilized for industrial fields because of poor development of suitable photon sources and optical devices. The developmental meaning, usable time and issue of a hard photon reduction lithography were surveyed as lithography in ultra-fine region below 0.1{mu}m. On hard photon analysis/evaluation technology, the industrial use of analysis, measurement and evaluation technologies by micro-beam was viewed, and optimum photon sources and optical systems were surveyed. Prediction of surface and surface layer modification by inner shell excitation, the future trend of this process and development of a vacuum ultraviolet light source were also surveyed. 383 refs., 153 figs., 17 tabs.

Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

According to the trend of car suspensions announced in 1989, not only sports cars but also sedans have extensively applied a multi-link type and a double-wishbone type which are to improve operation stability and comfortableness by reexamining all their fundamental structures. Active suspensions with electronic control have been put to practical use and adopted for the first time to mass-produced cars such as INFINITI'' and CELICA''. Concerning steerings, most types of light cars are now equipped with power steerings. Moreover, application of air bags has increased, and safety has been improved by commercialization of the first mechanical air bags in addition to the conventional electrical ones. As for brakes, more anti-lock brakes have been used for 4WD cars and low-displacement cars. Motorcars with a traction control system have consequently increased. Thus both the anti-lock brakes and the traction control system are contributing to the improvement in safety. 17 figs., 2 tabs.

It may be intended that CWM is manufactured in areas near coal producing areas in overseas countries and imported as a product requiring lower handling cost than in bulk products. In order to achieve this idea, it is necessary to establish a distribution and relaying system for product transportation inside and outside the country, including relaying bases for receiving, loading and storing the product. This paper reports results of the demonstration tests performed since 1992 to 1996. In the tests, CWM made from Chinese coals was transported from Shijiu Port to the Hibiki relaying base in the city of Kita-Kyushu on 5000 DWT ocean vessels, unloaded, stored, and loaded again on 700 DWT domestic vessels for distribution to users. Since the inauguration of transportations, 40,000 tons of CWM were delivered yearly to the Okayama plant of Tayca Company, and about 20,000 tons to the Mizushima power plant of the Chubu Electric Power Company over a period from 1995 to 1996. During the period, a number of findings were acquired in different aspects, including quality control of incoming and outgoing CWM, stability in quantity and properties, loading and unloading works, and transportation. Although reduction in subsidence during transportation and storage was indicated desirable, the practical applicability was verified for the relaying system as a whole. 4 refs., 15 figs., 3 tabs.

This paper looks back the history of applications of laser processing in the automobile industry, and introduces contents of some particularly unique applications from among them. The CO2 laser and YAG laser that are used mainly have increased their outputs with the times, and 50-kW CO2 laser and 4-kW YAG laser have now become available commercially. The laser processing has become used widely for cutting purpose in Japan, which is in contrast with their high application to welding in Europe and America. Cutting thick plates has been developed recently, which is applicable to plates as thick as about 25 mm. A flexible system in which YAG laser is combined with an optical fiber/articulated robot is operating for three-dimensional shape processing. Automobile makers are adopting laser processing for welding in place of the electron beam welding that has been used conventionally. The process is used also for a number of other applications including surface reformation, such as surface quenching for cylinder liner, and valve seat padding. 8 refs., 8 figs.

Study was made on the applicability of mechanical milling (MM) and mechanical alloying (MA) to Fe system alloys. Metastable austenitic stainless steels such as SUS316L and SUS304L form {alpha} phases by strain induced transformation due to MM, and are subjected to further plastic deformation. Nano-size fine structure was obtained through inverse transformation into austenite({gamma}) by heat treatment or high-temperature sintering of MM powder. Fine microduplex structure of 620nm in average crystal grain size was obtained for SUS316L. This material showed nearly 3.3 times higher 0.2% tensile proof stress, nearly 1.8 times higher tensile strength, and 35% higher elongation than conventional ingot steels. Solid solution powder of 12Cr-Mo-W ferritic steel was sintered by hot isostatic pressing (HIP) under low- temperature and ultrahigh-pressure conditions of 650degC and 588MPa. The as-HIP`ed sample and sample annealed at 800degC showed average {alpha} grain sizes of 33 and 50nm, respectively, and a strength twice as high as that of 12Cr steel. 97 refs., 60 figs., 18 tabs.

The paper described the results of the survey of the nonferrous metal field relating to the FY 1999 long-term energy technology strategy. The needs for electronics products are increasing toward the 21st century. Domestically the competition with other countries in enlarging the market share has been intensifying. At the same time, the smaller the size of device becomes, the more the barriers in technology to be overcome increase. In the development of Si wafer to cope with such a situation, there are a lot of problems to be broken down in liaison with industry/government/university. Compound semiconductors are higher in speed than Si, and have a marked feature of producing light, but are difficult in crystal growth. It was in the past 20 years that the development of commercialization technology has rapidly advanced. Compound semiconductors are indispensable as a device in the energy problem which strongly influences the global environment. In the U.S., for the military use, a policy for upbringing national industries has been carried out since 1993. The role of compound semiconductor materials playing as the fundamental industry which supports the semiconductor industry and system industry as the nation's core industries is important even in Japan the same as in the U.S. (NEDO)

This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a semiconductor equipment field, viewing until 5-10 years after. For the future semiconductor industry, the favorable cycling of creation of new demands through performance improvement, and further technology innovation through market expansion is essential absolutely. Since technology development is followed by investment, not only the performance of each equipment but also the higher productivity and cost balance of the whole factory are essential. Self-intelligent function and networking are thus necessary for the equipment. As measures for environment preservation and energy saving, such innovative technologies are required as recycling, reuse, reaction process improvement and alternative technology. Because of diverse final products and a short life time of products, a large-scale collective investment is becoming difficult. A mini-line sequential investment production system according to demand scales is under investigation. Some issues such as micro-technology, realization of 300mm wafer, modularization, CIM, reliability and standardization are also described. (NEDO)

A polygonal mirror in a printer and the main shaft of a high-speed milling machine are used as models for the development of technology for applying C/C (carbon/carbon) composite materials to machine components that are required to turn at high speeds. Various C/C composites are tested for flexural strength and thermal expansion for the designing and manufacturing of C/C composites for the polygonal mirror and main shaft. The first coating on the C/C composite is deposited by laser/plasma hybrid spraying, and is a Mo coating. A spraying robot is experimentally built for homogeneous coating. In the case of polygonal mirror, an Al coating is deposited further by the gas-deposition method. The polygonal mirror proves excellent in both dimension and reflectance, and attains the target speed of 45,000rpm. In the case of milling machine main shaft, however, it is not strong enough to withstand 40,000rpm although it is a success from a viewpoint of coating technology and manufacturing technology. 15 refs., 33 figs., 13 tabs.

Researches have been made to increase density of 200,000-kW class generator and to increase capacity of 600,000-kW class generator necessary for putting superconducting generator into practical use. This paper summarizes the achievements in fiscal 2000. In the study of increasing densities of superconductors and field windings, strands were fabricated, in which aging heat treatment conditions, number of aging, and processing degrees between each aging were varied, to increase the critical current of Nb-Ti strand, wherein as high critical current as corresponding to about 90% of the target was obtained. Possibility of increasing the critical current with the final processing degree in the range of 4 to 5 was verified from the relationship between the final processing degree and the critical current. In the study of increasing capacities of superconductors and field windings, findings were acquired on enhancement of conductor stability and reduction in AC loss, with regard to superconductor strands well balanced in the two elements. Prospects were obtained in achieving the AC loss of 200 kW/m{sup 3} in the targeted superconductor. The residual resistance ratio was found to be 200, showing sufficiently high value, and sufficient function was verified in the stabilized copper. In the research of design technologies, primary basic design was performed. (NEDO)

1982-01-01

Atomic energy has settled completely in Japan, and the new development has been achieved successively. But radioisotopes are closer to human life than atomic energy, and their roles in medical treatment, biology, agriculture, scientific research and the development of industrial technologies are indispensable. In order to open up a new field or to develop a new technology, the exact selection of isotopes corresponding to needs, the planning of experiment based on correct data, detection and quantitative determination are necessary to obtain new information. This book is intended to meet such demand. By using this book, readers are released from the troubles to select among complicated enormous data and to make correct judgement. The data of wide range accumulated in the Isotope Training Institute are presented to public in the form of this book. The fundamentals, the list of isotopes and decay scheme, natural radioactive nuclides, nuclear fission products, photon weakening coefficient, interaction of charged particles, orbital electrons, radiation sources and detectors, measurement of liquid scintillation and formation of radioactive nuclides are the main contents.

Two years have elapsed since the accident in Chernobyl nuclear power station shocked those concerned with nuclear power generation. The effect that this accident exerted on human environment has still continued directly and indirectly, and the reports on the effect have been made in various countries and by international organizations. In Japan, about the exposure dose of Japanese people due to this accident, the Nuclear Safety Commission and Japan Atomic Energy Research Institute issued the reports. In this report, the available data concerning the envrionmental radioactivity level in Japan due to the Chernobyl accident are collected, and the evaluation of exposure dose which seems most appropriate from the present day scientific viewpoint was attempted by the detailed analysis in the National Institute of Radiological Sciences. The enormous number of the data observed in various parts of Japan were different in sampling, locality, time and measuring method, so difficulty arose frequently. The maximum concentration of I-131 in floating dust was 2.5 Bq/m 3 observed in Fukui, and the same kinds of radioactive nuclides as those in Europe were detected. (Kako, I.)

In nuclear power stations, remote operation devices have been positively developed and applied, thus largely contributed to the reduction of the radiation exposure of workers. However, when requirements are diversified, the number of devices increases, and their management becomes complicated. The largest obstacle to the adaption of versatile robots in nuclear power stations is the environmental condition, and the small size for narrow space and the capability to withstand severe temperature, humidity and radiation must be ensured with high reliability. Mitsubishi Heavy Industries, Ltd. carried out the development of the manipulator for light works, which takes early counter-measures to the abnormality during operation, for five years as the subsidized project by the Ministry of International Trade and Industry. This robot is composed of a slave robot working in vessels and the central control system. The slave robot comprises a modular manipulator arm, the slave controller, a running carriage and the three-dimensional visual system. The components of the central control system are connected with optical fibers. The features and function and applicability of this manipulator are described. (Kako, I.)

Recently, anisotropic materials have been used widely for reactor core elements and fast flying objects, therefore, the problem of thermal stress in anisotropic bodies has been studied actively. In this study, the unsteady plane thermal stress in an orthotropic rectangular thin plate heated by the temperature of ambient medium was analyzed, taking the heat transfer on both surfaces into account. The influence that the anisotropy of material constants and the heat transfer on both surfaces exert on the temperature and thermal stress of the plate was examined. Moreover, in order to investigate into the effect of the aspect ratio of the plate on the temperature and thermal stress, the unsteady distributions of temperature and thermal stress in an orthotropic semi-infinite band, of which the end surfaces are heated by ambient medium, were analyzed. The numerical calculation was carried out, and the results are shown. Before, it was difficult to satisfy the boundary condition related to shearing stress, accordingly, the analysis has not been performed, but in this study, it was shown that the analysis is possible.

1988-01-01

In the development of a rule-based expert system, one of the key issues is how to acquire knowledge and to build a knowledge base. When the knowledge base of DISKET was built, which is an expert system for nuclear reactor accident diagnosis developed in Japan Atomic Energy Research Institute, several problems have been experienced. To write rules is a time-consuming task, and it was difficult to keep the objectivity and consistency of rules as the number of rules increased. Certainty factors must be determined often according to engineering judgement, i.e. empirically or intuitively. A systematic approach was attempted to cope with these difficulties and to build efficiently an objective knowledge base. The approach described in this paper is based on the concept that a prototype knowledge base, colloquially speaking an initial guess, should first be generated in a systematic way, then it is modified or improved by human experts for practical use. Factor analysis was used as the systematic way. DISKET system, the procedure of building a knowledge base, and the verification of the approach are reported. (Kako, I.)

1985-01-01

In order to develop energy-saving techniques and new energy techniques, and also most advanced techniques by making industrial equipment with high performance, heat transfer performance frequently becomes an important problem. In addition, the improvement of conventional heat transfer techniques and the device of new heat transfer techniques are often required. It is most proper that chemical engineers engage in the research and development for enhancing heat transfer. The research and development for enhancing heat transfer are important to heighten heat exchange efficiency or to cool equipment for preventing overheat in high temperature heat transfer system. In this paper, the techniques of enhancing radiative heat transfer and the improvement of radiative heat transfer characteristics are reported. Radiative heat transfer is proportional to fourth power of absolute temperature, and it does not require any heat transfer medium, but efficient heat-radiation converters are necessary. As the techniques of enhancing radiative heat transfer, the increase of emission and absorption areas, the installation of emissive structures and the improvement of radiative characteristics are discussed.

1988-01-01

It has been known that the mixture of an unsaturated prepolymer and a thiolated prepolymer can be cured by the relatively low dose of electron beam irradiation. As a thiolated prepolymer, polyether-polythiol prepolymer has been in the market. However, the coating films derived from the composition comprising the thiolated prepolymer do not have enough mechanical strength for practical use. In this study, the synthesis of thiolterminated urethane prepolymer and the coating composition comprising this prepolymer for obtaining the coating films having good mechanical properties were investigated. The raw materials used for the synthesis of thiolterminated urethane prepolymer are shown. Its synthesis and the measurement of thiol content, coating formation, the electron beam curing of the coatings and the testing method of coated film performance are explained. The results of the synthesis of the thiolterminated urethane prepolymer, the thermal stability, curability, physical properties and adhesion strength of the coatings are reported. The coatings can be applied to steel and PVC films, and used as the adhesive for steel-PVC film laminates. (Kako, I.)

The buildings in nuclear power stations are the reinforced concrete structures which are constructed with the massive members having much rein forcing bar quantity and relatively high strength due to the requirement of aseismatic capability, shielding and others. Also their scale is large, and in the case of a power station of one million kW class, concrete as much as 300,000 m 3 is used for one plant. Accordingly, at the time of construction, the case of stably supplying the concrete of high quality in large quantity by installing the facilities of manufacturing ready mixed concrete at construction sites is frequent. Moreover, electric power companies carry out thorough quality control to undergo the inspection before use by the Agency of Natural Resources and Energy from the aspects of materials, structures and strength. Since prestressed concrete containment vessels were adopted for No.3 and No.4 plants, the quality of concrete and the facilities for manufacturing ready mixed concrete were examined in detail. The precooling facilities for concrete and the effect of precooling are reported. (Kako, I.)

The samples of fresh water, 100 l each, were collected. The carriers of Sr and Cs were added immediately after the sampling, and the samples were vigorously stirred and filtered, then passed through cation exchange columns. Sr and Cs were eluted with hydrochloric acid from the cation exchange columns. Sr-90 and Cs-137 were separated from the sample solutions by the methods described, and their activities were counted with low background beta counters for 60 min. The net rate of sample counting was corrected for the counter efficiency, recovery, self-absorption and decay. As the environmental data, the results of Sr-90 and Cs-137 in fresh water obtained from October, 1978, to June, 1979, and the locations of sampling are given. In a table, the months and the locations of sampling, pH, and the amounts of Sr-90 and Cs-137 (pCi/l) are shown. The maximum values are 0.39 pCi/l of Sr-90 and 0.09 pCi/l of Cs-137 found in Miho County, Fukui Prefecture, in December, 1978. (Kako, I.)

The recent negotiation of enterprisers and local people concerning the location of power stations tends to extend for long period because of diversified arguing points and the information exchange of high density, and also to be complicated by the interrelation with other points. It is a large problem to seek the policy of such negotiation for enterprisers to respond to local people. In this study, as the first step, the policy and action appeared in location negotiations and the development of the negotiations were analyzed on the cases of location, and two kinds of the model analysis were carried out, taking fishery compensation negotiation as the object among them. The knowledge was obtained about what response to local fishery associations is effective to promote the location. The classification of location negotiation and the factors affecting the development of negotiation were investigated. It was shown to be effective to divide the process of location negotiation into five stages of advancement. The model analysis was carried out according to game theory and by gaming simulation method. The results are reported. (Kako, I.)

Vegetables breed by seeds and vegetative organs. In main vegetables, the differentiation of clopping types, the adoption of monoculture and year-round production and shipment are carried out, adapting to various socio-economic and cultivation conditions. Protected agriculture has advanced mainly for fruit vegetables, and the seeds for sale have become almost hybrid varieties. Reflecting this situation, the demand for breeding is diversified and characteristic. The present status of mutation breeding of vegetables is not yet well under way, but reports of about 40 raised varieties have been published in the world. The characters introduced by induced mutation and irradiation are compact form, harvesting aptitude, the forms and properties of stems and leaves, anti-lodging property, the size, form and uniformity of fruits, male sterility and so on. The radiation sources used were mostly gamma ray or X-ray, but sometimes, combined irradiation was used. Results obtained in Japan include: burdocks as an example to gamma ray irradiation of seeds; tomatoes as an example of inducing compound resistance against disease injury; and lettuce as an example of internal beta irradiation.

The reliability and safety of nuclear power plants have decisive meaning under the situation that nuclear power generation steadily increases, and among various measures aiming at ensuring the reliability and safety in the operation of nuclear power plants, the countermeasures for protecting reactor core, main process equipment and high pressure circuits from damage have the important role, and the monitoring of condition and the organization of forecast, which are carried out continuously or periodically during the operation of nuclear power stations using the diagnostic expert system specially developed for the purpose, are included in them. Such monitoring enables the early detection of mechanical damage, increase of vibration, defects caused during operation and so on in reactor cores and primary and secondary circuits, and the continuous watching of defect developments. Also boiling in a core is detected, the place of abnormality occurrence is identified, and the intensity and characteristics of boiling are determined, thus the occurrence of dangerous condition is prevented. The developments of an in-core monitoring system and noise diagnostic systems are reported. (Kako, I.)

1985-01-01

Under the condition of mechanical load, on which the thermal stress due to temperature change is superposed, the deformation behavior of structural materials is affected by not only loading history but also temperature history. Also at the time of working materials, the case that the relation between plastic deformation and temperature change becomes a problem is not few, such as cold working after hot rolling. In this study, the effect of temperature change exerted on the plastic deformation of SUS 304 stainless steel was examined, as this material has been frequently used as a high temperature structural material. That is, the plastic deformation behavior at a certain temperature after prestrain was applied at a different temperature was experimentally determined under various temperature and load conditions. Moreover, the quantitative evaluation of the results obtained was attempted by using the concept of an equal plastic strain curved surface. The test pieces and the experimental method, the behavior in uniaxial loading and the behavior in combined loading are reported. (Kako, I.)

1981-01-01

Sea water was collected at fixed stations where the effect of terrestrial fresh water from rivers was expected to be negligibly small. Weather conditions were also considered, and the sampling was carried out after a few days in which rain did not fall. Attention was paid to avoid the contamination in sampling and storing. The sample was stored in 20 l polyethylene containers in the acidified state of pH lower than 3. 200 ml of sea water was also collected at the same stations for the determination of chlorinity. The radiochemical separation of strontium-90 and cesium-137 was performed, and the mounted precipitates were counted for activity using low background beta counters normally for 60 min. Net sample counting rates were corrected to obtain the content of strontium-90 and cesium-137 radioactivity per sample aliquot, and concentrations of these nuclides in the original sample were calculated. The maximum values obtained were 0.16 pCi/l of Sr-90 in Osaka-bay and 0.17 pCi/l of Cs-137 in Mutsu-bay in August, 1981. (Kako, I.)

Radioactive waste management

International Nuclear Information System (INIS)

Strohl, P.

1985-01-01

The OECD Nuclear Energy Agency (NEA) attaches considerable importance to its cooperation with Japan. It was said in the annual conference in 1977 that the presentation of the acceptable policy regarding radioactive waste management is the largest single factor for gaining public confidence when nuclear power is adopted with assurance. The risk connected with radioactive wastes was often presented as the major obstacle to the development of nuclear energy, however, an overall impression of optimism and confidence prevailed by the technical appraisal of the situation in this field by the committee of the NEA. This evolution can be easily explained by the significant progress achieved in radioactive waste management both at the technical level and with respect to the implementation of special legislation and the establishment of specialized institutions and financing schemes. More research will focus on the optimization of the technical, safety and economic aspects of specific engineering designs at specific sites on the long term isolation of wastes, and the NEA contributes to this general effort. The implementation of disposal programs is also in progress. (Kako, I.)

The Nuclear Safety Commission reported to the Minister of International Trade and Industry after prudent deliberation on this alteration problem which had been inquired on August 28, 1986. It was recognized that the technical capability of the applicant is appropriate, as the result of deliberation. It was judged that the safety after this alteration of the installation of the reactor facilities can be ensured. As the result of examining new type 8 x 8 zirconium liner fuel, there was no problem in its mechanical design, the analysis of dynamical characteristics, and the analysis of abnormal transient change and accident in operation. As to the change of the average degree of enrichment of replacement fuel, the thermonuclear design of the reactor core was adequate. In the incineration of spent resin and filter sludge, the effect of radioactive substances to the environment was negligible. The safety after abolishing the auxiliary protection function against exhaust radioactivity is ensured with a rare gas holdup equipment. The soundness of fuel and the soundness of reactor coolant pressure boundary are maintained in abnormal transient change and accident. (Kako, I.).

In the incineration of spent resin and filter sludge, the effect of radioactive substances to the environment was negligible. The safety after abolishing the auxiliary protection function against exhaust radioactivity is ensured with a rare gas holdup equipment. The soundness of fuel and the soundness of reactor coolant pressure boundary are maintained in abnormal transient change and accident. (Kako, I.)

1982-01-01

Recently, the thermal and nuclear power stations in Japan are often exposed directly to severe sea condition owing to the situation of their location and construction. In this paper, underwater asphalt construction method (asphalt mats, sand mastic) and hydrocrete construction method (underwater unseparable concrete) are described as the reinforcing method for littoral structures such as breakwaters, protective banks, water intakes and discharge chennels. The asphalt mats are formed in precast state, burying reinforcing core materials such as glass fiber nets or wires in asphalt mastic, the mixture of asphalt, filler and aggregate. The sand mastic is the fluid asphalt compound, in which asphalt, stone dust and sand are heated and mixed, and is poured and solidified into the gaps in rubble mounds in water, to reinforce them. The hydrocrete is the underwater concrete of high quality made by blending special polymer compound to ordinary concrete, which does not separate during free descent in water, and the contamination of water quality is scarce. The features and applications of these construction methods are explained. Also, the examples of actual construction works are shown. (Kako, I.)

The aseismatic design of nuclear power generation facilities carried out in Japan at present must conform to the ''Guideline for aseismatic design examination regarding power reactor facilities'' decided by the Atomic Energy Commission in 1978. In this guideline, the earthquake motion used for the analysis of dynamic earthquake response is to be given in the form of the magnitude determined on the basis of the investigation of historical earthquakes and active faults around construction sites and the response spectra corresponding to the distance from epicenters. Accordingly when the analysis of dynamic earthquake response is actually carried out, the simulated earthquake motion made in conformity with these set up response spectra is used as the input earthquake motion for the design. For the purpose of establishing the techniques making simulated earthquake motion which is more appropriate and rational from engineering viewpoint, the research was carried out, and the results are summarized in this paper. The techniques for making simulated earthquake motion, the response of buildings and the response spectra of floors are described. (Kako, I.)

Extensive studies have been carried out on the structure of X-ray spectra from the highly stripped ions of first transition elements and their behavior in high temperature plasma, using a high resolution crystal spectrometer. Calculation was made on the design and the use of a curved crystal spectrometer for plasma diagnostics. A Johann type crystal spectrometer for measuring X-ray lines was constructed on the basis of the calculation. The characteristics of curved crystals of LiF, Ge and quartz used for the measurement of Kα lines from first transition elements were investigated. Vacuum sparks have been formed for producing high temperature plasma which emits X-ray lines from highly stripped ions. Two different structures of vacuum spark plasma were shown, that is, thermalized point plasma and extended plasma associated with non-thermal electrons. The X-ray lines from the extended plasma, those associated with the K shell from the point plasma and the Kα lines of Ti through Zn from the point plasma have been observed. (Kako, I.)

1982-01-01

In the age of energy conservation at present, the power generation facilities have been examined from the viewpoint of performance, endurance and economy, and in particular, the prevention of the loss due to the corrosion of various facilities is one of most important problems. Since circulating water pipings are in contact with sea water and soil, the peculiar corrosion phenomena are brought about on their external and internal surfaces. Namely, the pitting corrosion due to the environment of soil quality difference, the defects of coating and the contact with reinforcing bars in concrete occurs on the external surface, and the overall corrosion due to the increase of flow velocity and the pitting corrosion due to the defects of coating, the contact with different kinds of metals and the gap in corrosion-resistant steel occur on the internal surface. As the measures for corrosion prevention, corrosion-preventive coating and electric corrosion prevention are applied. The principle, the potential and current density, the system, the design procedure and the examples of application of electric corrosion prevention are described. (Kako, I.)

Recently, the exciting system for electric power heating as seen in nuclear fusion plasma heating and medical purpose has been actively studied and developed. Since such system treats basically a neighborhood field, various problems unlike conventional exciting system for communication arise. In such situation, the structure having the waveguides of simple and robust construction as the main body has been proposed. In this exciting system including the condition of media, the complex distribution of a neighborhood field based on a three-dimensional structure exerts an important effect on the characteristics. Especially in large power excitation, the higher mode of relatively small power distribution cannot be neglected. Besides, also a transient field distribution exerts an important effect on the characteristics, and the time response analysis is required. In this analysis, by the three-dimensional time response analysis method using Bergeron method, the unified analysis of the total system comprising a cutoff waveguide, a coaxial exciting part and a heating region was carried out for determining a radiation neighborhood electromagnetic field by a cutoff waveguide antenna.

When guiding a complex process and associated intermeshed systems in a nuclear power plant, a primary issue consists of the call for excellent information. Technically speaking, today's centralized control rooms are at the end of a development phase which has been governed by the introduction of remote information and remote control systems. But by centralization, an information overload problem arose, and it has been solved by dividing panels according to systems, operational phases and specific tasks. In addition, the overview and relationship of systems have been visualized by mimic diagrams. It is attempted to make transparent the technical back-ground of the processes and systems to be controlled, thus to provide the necessary basis for understanding the problems of operators. Practical examples are used for the purpose. The information dilemma, the systems for high level information, automation and information, plant safety and information, and the problem of where to go from here are described. Computerized operator aids must be discussed along assistance in information and assistance in automatic control. (Kako, I.)

1983-05-01

The methods of generating group constants have been studied to predict accurately the nuclear characteristics of fast reactors. In resonance energy region, the accuracy of the group constants was investigated, which were calculated by the approximate weighting spectrum used for a conventional standards group constant set such as ABBN. It was shown that the basic assumption of constant collision density for group constant calculation was not always satisfactory. Moreover, a multilevel formula was derived without losing the useful characteristics of the Breit-Wigner single level formula. Using this formula, the interference effect between resonances was examined. In addition, the mutual interference between different resonant nuclides was calculated. The cause of a systematic dependence of effective multiplication factors on U-238 concentration ratio was studied, and the cross section adjustment was performed. In the unresolved resonance region, the average resonance parameters were searched. As a result, the JFS-2 set was generated, and several studies were performed to advance the concept of the group constant set JFS-2. (Kako, I.)

The development of remote control, automatic equipment for nuclear power stations has been promoted to raise the rate of operation of plants by shortening regular inspection period, to improve the safety and reliability of inspection and maintenance works by mechanization, to reduce the radiation exposure dose of workers and to reduce the manpower required for works. The taking-off of control rod drives from reactors and fixing again have been mechanized, but the disassembling, cleaning, inspection and assembling of control rod drives are manually carried out. Therefore, Hitachi Ltd. has exerted effort to develop the automatic equipment for this purpose. The target of development, investigation, the construction and function of the equipment, the performance and the effect of adopting it are reported. The equipment for the volume reduction of spent fuel channel boxes and spent control rods is developed since these are major high level radioactive solid wastes, and their apparent volume is large. Also the target of development, investigated things, the construction and function of the equipment, the performance and the effect of adopting it are reported. (Kako, I.)

Tomoda, Yoshio

1981-01-01

In relation to the safe maintenance of nuclear power plants, it is necessary to prevent reactor coolant pipings from burst type failure caused by the unstable propagation of defects and cracks, such as stress corrosion cracking and fatigue cracks. In ductile materials, crack propagation is stable in tensile loading under fixed grip condition, when a specimen is controlled to deform in proportion to the increase of tensile load. However, it has been known that the instability of ductile cracks occurs after tensile load reached the maximum, especially under constant loading condition arising in the loading devices with high compliance or low tensile rigidity. In order to confirm the reliability of SUS 304 stainless pipes subjected to SCC, the crack propagation behavior was examined with the specimens having center cracks, using both testing machines with high compliance and low compliance. The instability of ductile cracks and the propagation velocity of unstable cracks were analyzed, and the calculated results were compated with the experimental results. Not only the compliance of testing machines but also the conditions of specimens affected the propagation of cracks. (Kako, I.)

By the continuous monitoring and grasp of operational condition, the preventive maintenance and the improvement of the rate of operation can be expected. Also it is desirable in view of the reduction of radiation exposure of operators. The mechanization of and the labor saving in inspection and maintenance works is necessary because skilled workers will be short. The design and the composition of the system and its tests are reported. (Kako, I.)

Azuma, Takao; Saito, Shinobu

1984-01-01

In rotary machines, at the time of earthquakes, whether the rotating part and stationary part touch or whether the bearings and seals are damaged or not are problems. In order to examine these problems, it is necessary to analyze the seismic response of a rotary shaft or sometimes a casing system. But the conventional analysis methods are unsatisfactory. Accordingly, in the case of a general shaft system supported with slide bearings and on which gyro effect acts, complex modal method must be used. This calculation method is explained in detail in the book of Lancaster, however, when this method is applied to the seismic response of rotary shafts, the calculation time is considerably different according to the method of final integration. In this study, good results were obtained when the method which did not depend on numerical integration was attempted. The equation of motion and its solution, the displacement vector of a foundation, the verification of the calculation program and the example of calculating the seismic response of two coupled rotor shafts are reported.

1985-01-01

Recently, the research on free convection in vertical ducts has become active again concerning the problem of cooling in nuclear reactor accidents and the cooling of electronic equipment. Generally, in the convection heat transfer in ducts, when the wall temperature is high, the fluid temperature in the ducts conspicuously changes, accordingly, the temperature dependence of the properties cannot be neglected. In this study, about the laminar free convection in parallel plates and a circular pipe having uniform wall temperature, the numerical analysis taking the temperature dependence of all properties into account was carried out, thus the effect of the temperature dependence of properties exerted on free convection heat transfer was clarified, and the relation to the solution in constant properties was examined. Moreover, by introducing a new representative dimension, it was attempted to express mean heat transfer coefficient which is independent of the form of ducts in unified way. The mean Nusselt number of the constant property solution using entrance pressure condition agreed very well with the exact numerical solution. (Kako, I.)

1985-01-01

Accompanying the development of large electromagnetic pumps transporting liquid metals used as the heat transfer media for nuclear power plants and the electromagnetic flow meters of large capacity, many researches have been carried out on the flow of liquid metals under the action of magnetic field. The utilization of electromagnetic force for continuous casting facilities seems very effective for the total processes from refining to solidification. Hereafter, it will be a technologically important problem to clarify the behavior of electro-conductive fluid with free surface under the action of magnetic field concerning the non-contact control of the interface form of molten metals as well as the cooling problem in nuclear fusion reactors. In this study, first the flow phenomena of MHD liquid film flow in a magnetic field with intensity gradient was analytically examined, and the effect of magnetic field gradient exerted on liquid film thickness and liquid surface form was clarified. Next, the experiment using mercury was carried out. For liquid film flow, magnetic field gradient acted as a kind of non-contact weir. (Kako, I.)

1985-01-01

It has been well known that there are added mass and attenuation effect due to surrounding fluid in a structure vibrating in the fluid, and those are different according to the density and viscosity of the fluid and the form of the structure. In this study, in order to clarify added mass, the model of the vapor-liquid two-phase fluid with discontinuous density distribution was made. That is, bubbles were assumed to be a bubble column without bending stiffness and mass, and potential analysis was applied to a two-dimensional fluid field composed of a round section beam and the bubble column, thus their relative motion was hydrodynamically analyzed, and the theory for evaluating added mass was developed. The added mass experimentally determined from the response gain of a single round section cantilever when it was oscillated steadily, uniformly and at random in the vapor-liquid two-phase fluid being stationary as a whole and the theoretical result were examined by comparison, and equivalent bubble diameter was considered, thereafter, the validity of the model was examined.

Khan, M.A.

1985-01-01

In this panel discussing nonproliferation and international cooperation, the point of view of developing countries, both signatories and nonsignatories to the NPT, is presented. The slow-down in the growth of nuclear trade and industry has adversely affected the economy of energy deficient developing countries, depriving them of the benefits of atomic energy in agriculture and health as well as in power sector. Among 26 countries using nuclear energy for electricity generation, there are just half a dozen developing countries, and their share in the installed nuclear power capacity in the world is only 2 %. Besides the overall slow-down of global economy, the inflexible framework of treaties and quidelines is an important factor of the slow-down. The gradual erosion of mutual confidence between supplier states and recipients has arisen. The greatest threat to world peace is the growing nuclear arsenals of superpowers rather than nuclear proliferation. The role of the IAEA, the setting up of the Committee on Assurance of Supplies, the economy of developing countries and others are discussed. (Kako, I.)

State of art in incineration technology of radioactive combustible solid wastes

International Nuclear Information System (INIS)

Karita, Yoichi

1984-01-01

The features of incineration treatment as the method of treating radioactive wastes are the effect of volume reduction and inorganic stabilization (change to ash). The process of incineration treatment is roughly divided into dry process and wet process. But that in practical use is dry incineration by excess air combustion or suppressed combustion. The important things in incineration techniques are the techniques of exhaust gas treatment as well as combustion techniques. In Europe and USA, incineration has been practiced in laboratories and reprocessing plants for low level combustible solids, but the example of application in nuclear power stations is few. In Japan, though the fundamental techniques are based on the introduction from Europe, the incineration treatment of combustible solids has been carried out in laboratories, reprocessing plants, nuclear fuel production facilities and also nuclear power stations. The techniques of solidifying ash by incineration and the techniques of incinerating spent ion exchange resin are actively developed, and the development of the treatment of radioactive wastes in the lump including incineration also is in progress.

The spheromak technique, one of magnetic plasma containment techniques, has such arrangement of magnetic fields that the toroidal magnetic field is produced by the poloidal current flowing in plasma, and the poloidal magnetic field is produced by the toroidal current in plasma and the current in external coils. The authors proposed external flux core method as the technique of plasma formation by this spheromak method, in which the toroidal magnetic field is injected by the discharge using electrodes, whereas the poloidal magnetic field is injected by induction discharge without electrode. Its fundamental action was analyzed by computer simulation and confirmed by experiment. In this study, the behavior of the spheromak plasma produced was investigated in detail and summarized. The contents were the measurement of the spheromak configuration produced and the estimation of plasma parameters. The experimental setup, the principle of action, and the experimental results of magnetic field distribution obtained by a magnetic probe, ion current measured by an electrostatic probe, electron temperature by spectroscopic measurement and the behavior of spheromak plasma observed with an image converter camera are reported.

It was concluded that reactor the reactor operation is very dangerous for the reactor installation as well as safety of the staff under conditions of heavy water increased activity. Two fundamental arguments in favour of this conclusion are: insufficient possibility of reactor components inspection during maintenance and operation in the future period; difficulties in prevention of accidents that could occur is equally dangerous for the reactor facility and the environment. Cleaning and decontamination of the complete heavy water system is needed before the reactor operation starts in order to avoid possible failures or accidental events. [Serbo-Croat] Zakljuceno je da je eksploatacija reakora u uslovima postojece aktivnosti teskovodnog sistema veoma opasna po sam reaktor i po personal. Dva osnovna razloga u prilog ovog zakljucka su: nedovoljna mogucnost kontrole ispravnosti svih elemenata reaktora u toku remonta i ekspolatacije u predstojecem periodu; teskoca borbe sa udesima, koji bi se eventualno dogodili podjednako je opasna po instalaciju i okolinu.

This paper describes the surveys to establish strategies in the water related technology field. The primary question relates to realizing a circulation type water utilization society. Establishment of technologies as the element technologies is demanded on treating trace amount harmful substances and pathogenically harmful micro-organisms such as environmental hormones. Technologies requiring early practical application include high-efficiency energy recovery from sludge by means of methane fermentation, accelerated oxidation and super critical sludge decomposition, and composting. Structuring a comprehensive water management information system is also important. Establishment is demanded on such technologies as high stability sensors to treat harmful chemical substances, ultra high sensitivity bio-sensors for risk control, and detection of pathogenic micro-organisms. Alga identification and quantification systems are also necessary. In developing a contaminated environmental water and waste water purification system, early practical application is desired on technologies to purify soil and large-quantity diluted environmental waters by utilizing such natural materials as soil and activated carbons, biotope and micro-organisms. Manufacture of high function water by utilizing electromagnetic waves and ultra-sonic waves, and high-efficiency low-cost desalting technologies by means of membrane separation and evaporation are also required to be developed as water resource utilizing and water making technologies.

For increasing the excimer laser output, the discharge-exciting technologies necessary for designing the 2kW laser as the final target are established. The service life tests are started to demonstrate the member service life of 10{sup 9} shots or more. For development of the technologies for large-current composite ion beams, the plant is constructed to attain the final targets (100keV, 2A, width: 500mm or more). The currents reaching the substrate are developed to have 2.8mA with the Ar ion and 2.9mA with the Ca ion by, e.g., developing the ion sources and improving functions of the ion beam controlling systems. Researches on the surface modification technologies for producing the superhigh-quality metallic surfaces involve composite ion implantation and providing the modified layer of Ti-B-based hard compound. Corrosion rate of the modified titanium surface in a boiling sulfuric acid solution is reduced from 300mm/year to around 0.13mm/year. (NEDO)

The paper made a fundamental investigation to promote historical succession and creative use of the industrial scientific technology. As for the wind power generation, the large-scaling became centralized wind power plants, and the downsizing became the distribution to remote areas. The solar power generation shifted from the thermal power generation to the light power generation. There is also a method to use solar heat directly. As to power systems and the distribution of electric power, the subjects are a combination of energy source, geographical energy transportation, and heightening of consumption efficiency. It was indicated that the subjects changed with a lapse of time under technical/social/systematical conditions, and under the developable energy amount prescribed by those conditions. Heightening of efficiency, which can be realized even by a paper simulation, was realized partly helped by the developing measuring technology. The environmental problem becomes historically severe as a condition of the technical development. However, aimed at was the process where discharged matters and by-products are effectively used and disused matters are not produced. In the coal-thermal power generation, for example, a load of flue gas purification was reduced by the conversion to LNG. 253 refs., 65 figs., 12 tabs.

Thermo-mechanical treatment was given to improve further the superplastic behavior of SUS 304 stainless steel. In the SUS 304, martensite phase produced by the processing induced transformation may be reversely transformed to the primary austenite phase by high-temperature heating. Crystal grain size is micronized to 1 {mu} m by combining this reverse transformation and recrystallization of the austenite phase. However, the straining rate at that time is as extremely low as 1 times 10 {sup -4}/s or lower, which is insufficient for an industrial material. Therefore, the SUS 304 processed as described above was given again a series of thermo-mechanical treatment of the similar forced cold processing and annealing to ultra-micronize the crystalline particles. Majority of the crystalline particles have come to have a grain size of several hundred nm. This test piece showed a total elongation of 400% or more at a test temperature of 973 K and a straining rate of 1.8 times 10 {sup -3}/s or lower. In addition, the straining rate sensitivity index `m` at that time was 0.45 or higher. The superplastic deformation of the SUS 304 has a high possibility of being governed by dynamic recrystallization. 4 refs., 7 figs., 1 tab.

For the purpose of developing a fan for an engine with ultra-high by-pass ratio, the design code of three-dimensional cascade of blades based on the Navier-Stokes equation has already been developed. This paper describes a method created by calculation grids which are part of this design code. This method is to generate boundary fitted grids to calculate the flow field across a cascade of blades placed radially in the axially symmetric space between hub and casing. In this method, one-period domain of the cascade of blades is mapped on a box in computational space by a series of combined streching transformation and conformal mapping. The grid in physical space is then obtained by successive inverse conformal mapping on the grid points in computational space. The grid obtained in this method is H-type and has a periodicity which includes the inclination of grid lines at the periodic boundary. As an example of the grid generated by this method, grids for primary and secondary models of the fan with ultra-high by-pass ratio are shown. 6 refs., 12 figs.

Theory of parameter setting for data acquisition is arranged, mainly as to the seismic generating and receiving geometry. This paper also introduces an example of survey planning for three-dimensional land seismic exploration in progress. For the design of data acquisition, fundamental parameters are firstly determined on the basis of the characteristics of reflection records at a given district, and then, the layout of survey is determined. In this study, information through modeling based on the existing interpretation of geologic structures is also utilized, to reflect them for survey specifications. Land three-dimensional seismic survey was designed. Ground surface of the surveyed area consists of rice fields and hilly regions. The target was a nose-shaped structure in the depth about 2,500 m underground. A survey area of 4km{times}5km was set. Records in the shallow layers could not obtained when near offset was not ensured. Quality control of this distribution was important for grasping the shallow structure required. In this survey, the seismic generating point could be ensured more certainly than initially expected, which resulted in the sufficient security of near offset. 2 refs., 2 figs.

Preliminary experiment, investigation, and study are conducted prior to an experimental 3-D MT (magnetotelluric) survey planned to be carried out in the Minaminoshiro district, Akita Prefecture. In the preliminary investigation, MT measurements were performed at nine locations. It was anticipated that national highways, waste treatment plants, high-voltage power lines, and railways in presence in the district would act as noise sources. Although the impact of such noise was detected in the single site treatment result, yet it was found that it would be mostly eliminated by use of the remote reference treatment. It was learned that the resistivity structure in this district was quite low in contrast or 1 ohm/m against 30 ohm/m, but the result of 3-D model calculation indicated that a sufficient analysis would be possible even in such a low contrast case. Furthermore, as the result of the study of the density of observation stations in the magnetic field, it was found that changes in the response of magnetic field to the resistivity structure would be approximately 2% at the maximum and that the ill effect on the result of measurement would be of the negligible magnitude even when a single magnetic field observation station is deployed against plural electric field observation stations. 6 refs., 7 figs.

Analysis of the cycle-by-cycle variation of combustion in an internal combustion engine can be aided by the cycle-resolved measurement of the in-cylinder gas velocity. This paper describes the principle and operation of, and results obtained from, a particle coded-pulse velocimeter (PCPV) which measured the three components of velocity within normal planes to the axis of cylinder. The PCPV was applied to a 1.5 litre lean-burn engine in order to record the flow pattern. The intake air was seeded with light microcapsules of approximately 50{mu}m diameter which scattered light from a system of up to two sets of three plane laser sheets, distinguished by colour and thickness and pulsed by acousto-optic modulators, illuminating planes in the bore of the engine. The magnitudes of the axial and cross bore components of the velocity vector were found from the measured lengths and the duration of the particle tracks. The results from the PCPV measurements are time-resolved and instantaneously three-dimensional and thus the PCPV is capable of identifying the transition from a disordered flow, such as the intake process, to well-ordered flows such as occur during a compression process. The derived swirl and tumble ratios were relatively in good agreement with those measured by an impulse swirl meter. 6 refs., 8 figs., 1 tabs.

In the next generation media environment, it is required to remove the boundary between virtual and real environment. The integration of these heterogeneous environments will enhance the applicability and availability of the human media. The aim of this work is to pioneer the new technology of 3-D integrated information environment in which both virtual and real environment are embedded, and to give a guide into the construction of human media. Our results consists of three parts as follows : (1) As a benchmark of the 3-D integrated information environment, the immersive television which has surrounding multi-projection displays was investigated. (2) A new method to synthesize arbitrary 3-D viewpoint images from 2-D real images was developed. On the other hand, a new concept of ray data description was introduced to represent whole visual data of 3-D real space. In the new concept, the whole visual data is treated as a set of ray data. New methods for superimposing and handling ray data were proposed. Potential applicability of the methods were clarified. (3) In order to enhance the reality of operations under the virtual environment, quantitative analysis was performed assuming that the HMD (Head Mounted Display) was used for displaying 3-D space information.

Research and development was conducted of a technology for manufacturing an ultrathin polycrystalline silicon solar cell capable of efficiency enhancement and cost reduction earlier than the types of polycrystalline solar cells now available on the market. In this fiscal year, a silicon melt/solidification experimenting apparatus was built for manufacturing high-quality silicon ingots. Using an apparatus with its performance similar to the newly built one, a preliminary experiment was conducted involving high-purity silicon ingot manufacturing. In the experiment, boron was added to 75 kg of silicon for semiconductor devices so that its resistivity may be 0.5 ohm-cm. The silicon was melted in a quartz mold, and then subjected to unidirectional coagulation at 0.13 mm/min that started at the bottom to proceed upward. The result was a silicon ingot 44 cm times 44 cm times 17 cm (height). The ingot thus obtained exhibited 0.4-0.8 ohm-cm in resistivity distribution. Solar cells produced from the ingot showed a conversion rate of 16.9%. (NEDO)

Bioconsortia are microbial composites composing of more than two kinds of microorganisms with special functions. To utilize their advanced functions, some techniques have been developed for analyzing their functions and interactions, and for identification, separation and incubation of the constituent microbial groups. In FY 1997, an investigation was made on technology trends, domestic researchers, and research topics related to bioconsortia. To manage and promote the progress of research at the National Institute of Bioscience and Human-Technology where the centralized management of this project is conducted, meetings are held once a month to examine the progress at the institute, in which reports are made and discussions are held on how each research item is progressing. In addition, meetings of the committee to promote research are held every other month to consider and examine measures required for promoting the research. Re-entrustment of research has been made on two subjects, i.e., `Studies on biological significance of symbiotic microorganisms` by Prof. Ishikawa of the University of Tokyo, and `Study on the relationship between the biosynthesis of useful terpenic materials of plant origin and the differentiation of plant tissues, and their effective production by plant cell cultures` by Prof. Inoue of Gifu Pharmaceutical University. 27 refs., 13 figs., 1 tab.

The paper described the results of the survey of the nonferrous metal field relating to the FY 1999 long-term energy technology strategy. The needs for electronics products are increasing toward the 21st century. Domestically the competition with other countries in enlarging the market share has been intensifying. At the same time, the smaller the size of device becomes, the more the barriers in technology to be overcome increase. In the development of Si wafer to cope with such a situation, there are a lot of problems to be broken down in liaison with industry/government/university. Compound semiconductors are higher in speed than Si, and have a marked feature of producing light, but are difficult in crystal growth. It was in the past 20 years that the development of commercialization technology has rapidly advanced. Compound semiconductors are indispensable as a device in the energy problem which strongly influences the global environment. In the U.S., for the military use, a policy for upbringing national industries has been carried out since 1993. The role of compound semiconductor materials playing as the fundamental industry which supports the semiconductor industry and system industry as the nation's core industries is important even in Japan the same as in the U.S. (NEDO)

Described herein are the results of the FY1994 research program for energy conversion technology using chemical reactions by the aid of solar energy. The demonstration runs were conducted by a bench-scale unit, which was operated stably for 100h, to produce promising results. The catalyst exhibits stable performance, without showing a sign of deactivation. It is found that the heat pump system works well, without being interfered with accumulated by-products. A heat of approximately 2,100kcal/h is recovered. It is confirmed that steam of 150{degree}C and 200{degree}C is generated from hot water of 80{degree}C and 95{degree}C, respectively. The bench-scale runs show a thermal efficiency of around 10%, which is lower than the target level. However, the runs with hydrogen-occluding alloy attain a process thermal efficiency of 30%. The system in which solar collector and chemical heat pump units are combined is evaluated with respect to its economic efficiency and operability for its eventual commercialization. 6 figs., 2 tabs.

The aim is to develop and popularize techniques relating to geological information such as thermal history. The efforts center about the application of a now-available core fracture measuring system to developed geothermal fields and about the development of new technologies. The measuring system is applied to some core cuttings collected from five boreholes in the Akinomiya district, Akita Prefecture, and the system is used for (1) the evaluation of homogenization temperatures of inclusions in the fluid, (2) the measurement of the points of melting from ice of inclusions in the fluid, and (3) the implementation of laser Raman spectroscopy. Under item (1), it is found that the minimum homogenization temperature of quartz phenocryst in the mother rock or of low-salinity fluid inclusion in a quartz vein is near the current subsurface temperature and that subsurface and reservoir temperatures may be known by evaluating their homogenization temperature. Under item (2), it is found that the NaCl equivalent salinity is distributed in the range of 0.0 to 25wt% and that, in this connection, there is difference between a fluid in a fluid flow and a fluid spurting as thermal water in the Akinomiya district. Under item (3), CO2, N{sub 2}, and CH{sub 4} are detected in most of the boreholes. Efforts are exerted to develop a hydrothermal fluid analyzing technique using a rapid rock dating method and traces of chemical ingredients in hydrothermal minerals. (NEDO)

The project aims to establish basic technologies for the mass culture of cells by utilizing the features of animal cells, which will enable a large, stable supply of fine chemicals such as highly functional physiologically active proteins whose industrial production the conventional technique of synthesis fails to realize. For this purpose, efforts are exerted to select cells which are capable of producing target substances, to breed highly productive strains, to develop a serumless medium that satisfies demands for an all-purpose feature and heat sterilization, and to develop technologies of high-density culture and effective refining, etc. Some DNA (deoxyribonucleic acid) recombination technologies are also resorted to. As the result, a high-density culture of 2 times 10{sup 8} cells/ml has become available. Production is now feasible of various differentiation-inducing elements such as monoclonal antibodies with anti-HB virus activity, DIF, etc. Furthermore, cooperation with the Tsukuba University leads to the discovery of a novel vasopressor peptide (endothelin). The heat sterilization accepting serumless medium, which is put to practical use as the first of the kind in the world under this research and development project, contributes to the advancement of basic studies about cell biology.

A sharp rise in industrial productivity in Asia countries indicates a rising level of R and D technology. Since Japan has not clearly grasped the R and D ability in these countries, it has not given appropriate personnel/material R and D support to them. Therefore, for the purpose of exactly grasping the R and D ability of Asian countries (Korea, Taiwan, the Philippines, Indonesia and India) and studying an effective and appropriate method for R and D cooperation, a survey was conducted of R and D potentials in Asia and R and D support policies of the countries. As a result of the survey, the following are taken up as items to be considered: promotion of exchanges between Tsukuba, etc. in Japan and research/university towns and science parks being constructed in lots of countries, participation of private companies in high-tech joint work in cooperation with Japan, sending information from Japan using internet, etc. and exact grasp of needs at partner side, cooperation given to new comers without asking for research results (use of OB researchers, etc.) 25 refs., 39 figs., 59 tabs.

A phenomenon of excess heat generation through the electrolysis of heavy water using palladium metals as electrode can be recognized as new hydrogen energy. Its mechanism has been investigated for four years since FY 1993. In FY 1993, the New Hydrogen Energy Demonstration Research Center and the New Hydrogen Energy Demonstration Laboratory were organized, and the research was initiated. For the excess heat generation demonstration model tests, two types of electrolysis experimental units were constructed, and the Pd/D-based electrolysis experiments were initiated. For the measurements of excess heat using an open type electrolysis cell, there were rather large errors ranging from -13% to +7%. It is necessary to improve the accuracy. For the measurements using a fuel cell type electrolysis cell, generation of the excess heat ranging from 0% to 6% was observed. For the validity of this, it is required to confirm the long-term stability of calibration and cell components. For the correlation between the increase in absorbing rate and the generation of excess heat, results of 2 to 3% lower were obtained. 28 refs., 89 figs., 26 tabs.

This paper aims to develop a clean coal production process which excellently removes environmental pollutant, is low-costed, and need no particular systems for distribution of products. The result of the development was described paying attention to column flotation which is a technology to high-efficiently select particulate regions, particulate heavy media cyclone, magnetic separation, and the basic design of the process into which those above were integrated. The two-stage selection process, which is an integration of column flotation and particulate heavy media cyclone into the conventional coal preparation equipment, can produce low-ash clean coal at high separation efficiency and also suppress the rise in processing cost. This process was also effective for removal of sulfur content and trace metal elements. The use of clean coal at power plant can be effective for not only the reduction in ash treatment amount, but the aspect of boiler operation characteristics such as heat transfer efficiency of boiler furnace wall, ash related troubles, loads of electrostatic precipitator, loads of flue gas desulfurization facilities. 17 figs., 5 tabs.

Recent trend of CO2 laser cutting is described. The cutting speed has increased five times in these seven years, and cutting is now performed at 8m/min for a hole that satisfies a circularity of 50{mu}m. In the low-speed domain, again, cutting accuracy is as high as 20{mu}m. In the cutting of thick plates, laser encounters some difficulties, which include the increased thermal load on optical parts and devices in the oscillator, lessened cutting condition tolerance, variation in the accuracy of products, difficult cutting, etc. Discussed in this report are measures for correcting factors affecting product quality with reference taken to a thick soft steel plate. A laser beam emitted by an oscillator is condensed by and projected through a condenser lens, and the condensing capability is affected by various factors, such as the beam mode order, beam diameter, and focal length, etc. What is important is to find out the optimal conditions. The assist gas has to satisfy certain conditions because it assumes an important role in controlling the discharge of molten metal from cut grooves, heat generated by oxidation reaction, and cooling. The properties of the material to be cut also exert some influence. In the case of thick plate cutting, the cutting capability is governed by the geometry to be fabricated. Also employed for the prevention of poor jobs due to improper condition switchover and cutting routes is an optimal cutting condition control technique. 3 refs., 12 figs.

This paper describes features of high power YAG cutting. The optical fiber transmission YAG laser machining system has some advantages in which optical path length compensation unit is not required and measures for low power loss and dust are not required, when compared with the CO2 laser system. Its application to the cutting of stainless steel plates has attracted attention. Cutting tests of SUS304 were conducted using high power YAG laser. Cutting of SUS304 plate with a thickness of 40 mm could be successfully done at the power of 3.5 kW. Cutting tests of SUS304 pipes with a thickness of 8 mm in water under the depth of 20 m were also conducted using air as assist gas at the power of 2.5 kW. Excellent results were obtained without scale deposition. For the tests by the composite beam using 3 kW and 4 kW systems, SUS304 plate with a thickness of 50 mm could be cut at the cutting speed of 0.1 m/min. Laser cutting of pipes from the internal surface was conducted using a newly developed small machining head which can rotate in the peripheral direction. Excellent quality for welding was confirmed. Cutting speed and plate thickness were improved by combining water jet cutter and YAG laser unit. 6 refs., 10 figs.

This paper describes the measurement and analysis for clarifying solution structure of supercritical water and exhibition mechanism of solvent functions. It also describes the development of new processes using supercritical water as reaction solvent. The PVT measurements were conducted in the supercritical region using pure water and NaCl aqueous solution, to confirm the reduction of molar volume of the electrolyte solution. The hydration structure was examined in the supercritical aqueous solution by the molecular dynamic simulation. As a result, presence of hydrogen bond structure, where the contribution of two branching hydrogen bond can not be ignored, was suggested under the supercritical condition. Characteristics of supercritical aqueous solutions are analyzed through in-situ Raman and scattered X-ray spectral measurements. Moreover, this paper introduces developments of some processes in the supercritical water, such as decomposition of wasted polymers, recovery of chemical materials, reforming of heavy hydrocarbons by contact hydrogenation, and synthesis of fine powders of metal oxide by reaction crystallization.

This report describes results of the study on the excess heat generation phenomenon during the electrolysis of heavy water using palladium metals as electrode in FY 1995. For the measurements of excess heat using an open type electrolysis cell during the excess heat generation demonstration model tests, significant excess heat beyond the range of input was not measured both for ICARUS-1 and for ICARUS-2. For the measurements using a fuel cell, high absorbing rate more than 0.85 was stably achieved for highly pure Pd electrode material by heat treatment and surface treatment. The excess heat could be reproduced for plural tests. The heat recovery rate more than 98% was obtained using the NHE type flow calorimetric system. The excess heat measurements using this are examined. For the reactive palladium materials, various materials ranging from single crystal to cold working polycrystal materials were systematically used for the absorbing experiments. Benchmark tests were also conducted through the cooperation with related researchers. 18 refs., 135 figs., 28 tabs.

As feed screws, ball screws have become to be adopted in place of trapezoidal threads. The structure of ball screws is complex, but those are the indispensable component of NC machine tools and machining centers, and are frequently used for industrial robots. As the problems in the operation of ball screws, there are damage, life and the performance related to friction. As to the damage and life, though there is the problem of the load distribution on balls, the results of the research on rolling bearings are applied. The friction of ball screws consists of the friction of balls and a spiral groove, the friction of a ball and a ball, the friction in a ball-circulating mechanism and the viscous friction of lubricating oil. It was decided to synthetically examine the frictional performance of ball screws, such as driving torque, the variation of driving torque, efficiency, the formation of oil film and so on, under the working condition of wide range, using the screws with different accuracy and the nuts of various circuit number. The experimental setup and the processing of the experimental data, the driving performance of ball screws and so on are reported. (Kako, I.)

Nickel-base Alloy 600 is the principal material used for the steam generator tubes of PWRs. Generally, this alloy has been proven to be satisfactory for this application, however when it is subjected to extremely high stress level in PWR primary water, it may suffer from stress corrosion cracking. The authors have systematically studied the effects of test temperature and such metallurgical factors as cold working, chemical composition and heat treatment on the stress corrosion cracking of Alloy 600 in high temperature water, and also on that of Alloy 690 which is a promising material for the tubes and may provide improved crrosion resistance for steam generators. The test materials, the stress corrosion cracking test and the test results are reported. When the test temperature was raise, the stress corrosion cracking of the nickel-base alloys was accelerated. The time of stress corrosion cracking occurrence decreased with increasing applied stress, and it occurred at the stress level higher than the 0.2 % offset proof stress of Alloy 600. In Alloy 690, stress corrosion cracking was not observed at such stress level. Cold worked Alloy 600 showed higher resistance to stress corrosion cracking than the annealed alloy. (Kako, I.)

The Nuclear Safety Commission acknowledged the policy of handling this matter by Science and Technology Agency after having received a report from the Committee on Examination of Nuclear Fuel Safety on April 11, 1985, and carried out the deliberation. The investigation and deliberation of this matter were instructed by the NSC to the Committee on January 24, 1985. It was confirmed that the repair welding applied to the place of leak of the dissolution tanks would not hinder the expected test dissolution, and if the leak occurs, the measures to detect it properly have been taken. In order to confirm the soundness of the repair welding, the Power Reactor and Nuclear Fuel Development Corp. is to carry out the test dissolution for about 400 hours per one tank dividing into three runs, and the observation of appearance is to be made after every run. The time of test dissolution, the items and contents of inspection were confirmed to be adequate. Moreover, the immersion corrosion test of test pieces and the long term corrosion test in a laboratory are to be carried out. (Kako, I.)

Blueprint for domestic uranium enrichment

The AEC advisory committee on domestic production of uranium enrichment has studied for more than a year how to achieve the domestic enrichment of uranium by the construction and operation of a commercial enriching plant using centrifugal separation method, and the report was submitted to the Atomic Energy Commission on August 18, 1980. Japan has depended wholly on overseas services for her uranium enrichment needs, but the development of domestic enrichment has been carried on in parallel. The AEC decided to construct a uranium enrichment pilot plant using centrifuges, and it has been forwarded as a national project. The plant is operated by the Power Reactor and Nuclear Fuel Development Corp. since 1979. The capacity of the plant will be raised to approximately 75 ton SWU a year. The centrifuges already operated have provided the first delivery of fuel of about 1 ton for the ATR ''Fugen''. The demand-supply balance of uranium enrichment service, the significance of the domestic enrichment of uranium, the evaluation of uranium enrichment technology, the target for domestic enrichment plan, the measures to promote domestic uranium enrichment, and the promotion of the construction of a demonstration plant are reported.

1987-01-01

On the aseismatic walls of a reactor auxiliary building, many temporary openings are provided at the time of the construction for carrying equipment in later, due to the demand of shortening the construction period. Thus on the aseismatic walls, in most cases there are the joints due to the concrete placed later. As equipment tends to be unitized and become large, the quipment is placed close to the wall having an opening, consequently, the workability is poor, and the standardization of construction method is urgently demanded. The conventional method of closing temporary openings has the problems of safety and connecting reinforcing bars, therefore, the new construction method was proposed. In reactor buildings, the joints of walls are unavoidable, and since those are large scale structures, the joints are numerous. Therefore, at the joint parts, it abandoned and buried frames are used, it is advantageous in the time and cost of joint construction. In both cases, the mechanical properties were confirmed by the fundamental performance test partially modeling the joints and the verifying test modeling the whole walls. In this paper, the test of applying only shearing force to joint models is reported. (Kako, I.)

Nuclear power generation as seen from construction aspect

1984-01-01

The measures to vitalize atomic energy industry in low economical growth age are grasped from the viewpoint of heightening the quality of technology, and the improvement of the economical efficiency of nuclear power generation as seen from construction aspect is discussed. By 2000, the nuclear power generation in Japan will be increased by about four times to 62 million kW, and the proportion of nuclear power increases steadily. Recently, the nuclear power stations in Japan have been stably operated at high level, and the capacity ratio has exceeded 70 %. However, the power generation cost tends to rise, and it is feared that the economical advantage over thermal power will be lost. Recently, the construction cost of nuclear power plants has continued to rise, which causes the high cost of nuclear power. The reason of the high construction cost is in short too much quantity of materials and long construction period. As the proposal to reduce the construction cost, three stages of the rationalization are discussed, such as the rationalization of simulated earthquake for design and the improvement of reactor building design. The promotion of technical development is indispensable for the cost reduction. (Kako, I.)

As one of the methods to dispose long life actinide nuclides, the actinide burning fast reactor using only actinide wastes as the fuel has been proposed. Kawasaki Heavy Industries Ltd. carried out the conceptual examination on the ABFR cooled with helium gas, cooperating with Japan Atomic Energy Research Institute, and its feasibility and problems were clarified. In this report, the setting-up of various fundamental dimensions by the parameter survey of the thermal and flowing performance of the core, the examination of the thermal and flowing characteristics of the core based on the detailed power distribution, and the examination of the plant system centering around the main cooling system are outlined. The fuel is composed of actinide oxide and diluent MgO. The diluent is used for obtaining proper excess reactivity, and MgO has been taken up also in foreign countries, considering the compatibility with actinide oxide, the easiness of reprocessing and manufacture. The fuel element is of pin type, and actinide oxide and MgO pellets are in a SUS 316 cladding tube. This ABFR can treat the wastes from ten 1000 MWe power reactors, and has the power output of about 1000 MWt. (Kako, I.)

Considerations for tritium protection at a fusion reactor

International Nuclear Information System (INIS)

Easterly, C.E.

1982-01-01

The view on the radiological hazard associated with future fusion power stations as presented in this discussion is rarely supported by reasonably certain or reliably accurate prediction. This fact should not be taken as indicating a major programmatic deficiency. In fact, it is expected that large uncertainty would be present in health effect at the current level of technological development. The details of tritium exposure will be clarified, waiting for the operation of the Tritium System Test Assembly. Once the data base for the TSTA is established, future fusion design can be made based on economic cost/radiation exposure risk benefit. The actual execution of this cost/benefit analysis is complex because three populations are of interest: occupational work force, local population and global population. The knowledge of tritium management must be increased if D-T fusion reactors are to become compatible with the needs of utility companies. In order to exploit the differing hazard between HT and HTO, it is necessary to know much more about the mechanism of uncatalyzed conversion over a wide range of concentration and about the change caused by the variety of potential catalytic sequence in potential tritium leak.

As one of the large subjects for putting FBRs to practical use, the increase of the economical efficiency is pointed out, and for this purpose, the reduction of the construction cost by the simplification of system and the rationalization of equipment structures becomes an important target of development. The operational condition of FBR cooling system is high temperature above 500 deg C at core exit, and low pressure below 6 kg-cm 2 g. Consequently, the effect of earthquake load in the structural strength design is relatively large, accordingly the reduction of earthquake load is effective from the viewpoint of structural rationalization. Hitachi Ltd. considered that earthquake isolation is an effective means to reduce earthquake response, and has examined the effect and feasibility of introducing earthquake isolation into FBR plants for three years from 1984. In this study, the mechanical characteristics and endurance of the system suitable to the earthquake isolation of FBRs were examined, the effect of reducing earthquake response by earthquake isolation was grasped, and the effect of plant rationalization brought about by the reduction of earthquake input was examined. The summary of these studies is shown. (Kako, I.)

Cryogenic properties of V-bearing austenitic stainless steel

International Nuclear Information System (INIS)

Nohara, Kiyohiko

1985-01-01

A new type austenitic stainless steel which is expected as the cryogenic structural material for superconducting magnets has been developed. This steel is that vanadium was added to SUS 316 stainless steel of low carbon and high nitrogen, which has the sufficient strength and toughness at 4 K, and maintains the stable nonmagnetic state. This is applicable both to the solution state and the state of carrying out age hardening heat treatment for precipitating Nb 3 Sn subsequent to it. Accordingly, this material can be applied to the sheath material for nuclear fusion and the manufacture of superconducting magnets by Wind and React process besides the candidate material of superconducting magnets for nuclear fusion. This phenomenon is due to the fact that vanadium carbide precipitates in crystal grains before chrome carbide precipitates at grain boundaries, thus the precipitation of chrome carbide is suppressed. In this experiment, the effect of vanadium addition on the cryogenic properties of SUS 316 stainless steel was examined. The experimental method and the results of the effects of vanadium and nitrogen, solution treatment and precipitation aging, and the measurement of magnetism are reported. (Kako, I.)

In this experment, the blood ammonia and glutamine amide came from infused ammonia were determined when N-15 labeled ammonium acetate was intraportally infused into the chickens fed 5 or 20 % protein diet. The data obtained indicated that the infused ammonia was taken into blood glutamine amide, and also accumulated in blood as it is, in both dietary groups. 10 to 12 months old White Leghorn male birds were used. The experimental diet was fed once a day for 5 days to the birds weighting about 1.2 kg by 35 g per kg body weight. The experimental diet was consumed within 40 min in all cases. Cardiac and portal catheterization were performed for blood collection and ammonia infusion, respectively. After finishing the infusion, blood samples were taken to analyze the ammonia and glutamine contents and their N-15 enrichment. Statistical difference was not observed in the appearance of N-15 in ammonia and glutamine amide between two dietary groups. The N-15 enrichment in blood ammonia and the amide of plasma glutamine, and the calculated exogenous nitrogen in the ammonia and glutamine amide tended to be more in the 5 % protein diet group than the other.

1982-01-01

Styrene divinyl benzene copolymer (SDBC) is hydrophobic, and porous with large specific surface area. Utilizing these properties, the SDBC was used for the carrier of catalyst in water-hydrogen exchange reaction process, and the hydrophobic platinum catalyst with very high performance was able to be developed. However, the SDBC is usually fine particles smaller than 1 mm, and is not suitable as the filling catalyst for exchange reaction towers. Therefore, in this study, using only platinum as a catalyst metal, the improvement of the property of carriers was emphatically examined, and platinum bearing was proved with an optical or electron microscope. As the result, it was found that the SDBC catalyst showed high activity practically usable as the hydrophobic catalyst for heavy water or tritium exchange reaction. The characteristics of SDBC are explained. The manufacturing processes of the catalyst by making SDBC carriers with fine particles and letting them bear platinum are described. The results of the trial manufacture of spherical, extrusion-formed and honeycomb carrier catalysts are reported. Platinum must be dispersed over the large specific surface area of SDBC carriers.

In main vegetables, the differentiation of clopping types, the adoption of monoculture and year-round production and shipment are carried out, adapting to various socio-economic and cultivation conditions. Protected agriculture has advanced mainly for fruit vegetables, and the seeds for sale have become almost hybrid varieties. Reflecting the situation like this, the demand for breeding is diversified and characteristic, and the case of applying mutation breeding seems to be many. The present status of the mutation breeding of vegetables is not yet well under way, but about 40 raised varieties have been published in the world. The characters introduced by induced mutation and irradiation were compact form, harvesting aptitude, the forms and properties of stems and leaves, anti-lodging property, the size, form and uniformity of fruits, male sterility and so on. The radiation sources used were mostly gamma ray or X-ray, but sometimes, combined irradiation was used. As the results obtained in Japan, burdocks as an example of gamma ray irradiation to seeds, tomatoes as an example of inducing the compound resistance against disease injury and lettuces as an example of internal beta irradiation are reported.

The behavior of internal pressure creep rupture of the thin-walled cylinders with circumferential joints is affected by the combination of creep characteristics of parent materials and weld metals. In particular, the compatibility of the creep strain rate of parent materials and weld metals becomes an important controlling factor. The behavior of internal pressure creep of the welded parts in circumferential joint cylinders can be evaluated simply with the uniaxial creep data of parent materials and weld metals, considering it by approximately substituting with the creep behavior of a uniaxial longitudinal joint. The method of evaluation is, first, to analyze the breaking behavior of uniaxial longitudinal joints using the uniaxial creep characteristic values of parent materials and weld metals, and next, by combining the equation for the relation between the rupture times of uniaxial creep and internal pressure creep with the analyzed breaking behavior of uniaxial joints, the internal pressure creep rupture behavior of the cylinders with circumferential joints can be evaluated. The internal pressure creep behavior of the thin-walled cylinders with circumferential joints, their rupture life and the uniaxial creep rupture life of longitudinal joints, and the examination of Hastelloy X cylinders are reported.

The activities of the Research Committee on Marine Reactors are summarized, and the present status of marine reactors on the world is reviewed. The characteristics of marine reactors are discussed, and the prospect and problems of the research and development of an advanced marine reactor in Japan are reported. This Committee was established in fiscal year 1983, when the 'Mutsu' project was going to be on the right track, and the project of developing an advanced marine reactor was advanced.

Regarding the method of environmental test on the electric wires and cables used for the safety system in the containment vessels of nuclear power plants, the draft recommendation was issued by the Institute of Electrical Engineers of Japan in 1982. Its contents follow the IEEE Standard of USA, and are composed of the tests on the deterioration in normal operation, the case of LOCA and the prevention of spread of fire. In this report, as to the testing method regarding normal operation, the appropriate method and its basis are described in view of the recent experimental data. In the draft recommendation, the successive method carrying out irradiation after thermal deterioration is adopted, and both testing conditions are given. However, the fundamental problems remain in the propriety of the acceleration of deterioration and the multiplied effect of heat and radiation. The qualitative and quantitative data on these problems have been accumulated in various countries, therefore, the examination of the testing method was carried out based on these data. The dose rate dependence of radiation deterioration, the multiplied effect of radiation and heat, and the correlation of thermal deterioration rate with temperature are discussed. The appropriate method is proposed. (Kako, I.)

1984-01-01

The radiation damage accompanying ion irradiation and the various problems caused with it should be determined in principle by resolving Boltzmann's equations. However, in reality, those for a semi-infinite system cannot be generally resolved. Moreover, the effect of crystals, oblique incidence and so on make the situation more difficult. The analysis of the complicated phenomena of the collision in solids and the problems of radiation damage and sputtering accompanying them is possible in most cases only by computer simulation. At present, the methods of simulating the atomic collision phenomena in solids are roughly classified into molecular dynamics method and Monte Carlo method. In the molecular dynamics, Newton's equations are numerically calculated time-dependently as they are, and it has large merits that many body effect and nonlinear effect can be taken in consideration, but much computing time is required. The features and problems of the Monte Carlo simulation and nonlinear Monte Carlo simulation are described. The comparison of the Monte Carlo simulation codes calculating on the basis of two-body collision approximation, MARLOWE, TRIM and ACAT, was carried out through the calculation of the backscattering spectra of light ions.

In nuclear power stations, in order to carry out sound and stable operation, the routine inspection and regular inspection of machinery and equipment are performed, therefore, the transportation of heavy things is frequently carried out. Especially, the transportation of heavy things over the steps of passages and stairs requires much labor. Therefore, Chubu Electric Power Co., Inc. and Chubu Plant Service Co., Ltd. carried out the research on the development of a vehicle for transporting heavy components of nuclear power plants. In this research, it was aimed at developing a vehicle which can carry heavy components and get over a step, climb and descend stairs, and run through a narrow passage having many curves as well as running on flat ground. For this purpose, the actual state of the transportation of heavy things was investigated during the regular inspection of a nuclear power station, and on the basis of this results, a prototype vehicle was made and tested. Thereafter, a transporting vehicle of actual scale was made and tested. The investigation of actual state and the examination of the fundamental concept, the design, trial manufacture and verifying test are reported. (Kako, I.)

For operating nuclear power stations safely and economically, it is necessary to control nuclear fuel itself and reactor cores. Nuclear fuel must be controlled consistently in view of quantitative balance and operational method over the whole nuclear fuel cycle of uranium ore, fabrication, burning in reactors and reprocessing, based on the plan of using fuel in electric power companies. The control of the burning in reactors is called core management, and it is important because the users of fuel execute it. For dealing with such core management works, Shikoku Electric Power Co., Inc., has developed the computer code system for grasping the state of fuel exchange and the burning condition in reactors and used it since 1972. The outline of the core management in Ikata Power Station is reported in this paper centering around computing works. The core management works are divided into those at the time of regular inspection and those in operation. In the regular inspection, fuel inspection, fuel exchange and reactor physics test are performed. In operation, the burning condition of fuel is grasped. The technical computations corresponding to these works are explained, and the examples of computations are shown. (Kako, I.)

Production of reciprocal translocation lines and genetical analysis of tetravalent behavior in barley

Energy Technology Data Exchange (ETDEWEB)

Makino, Tokuhiko

1988-03-01

The seeds of a barley cultivar, Chikurinibaraki No.1 and of an early mutant line, Ea 52, derived from it were exposed to the external irradiation of gamma ray and thermal neutrons, and to the internal irradiation with the alpha ray from the nuclear reaction B-10 (n, alpha) Li-7 generated by the thermal neutron irradiation of B-10 imbibed seeds. The reciprocal translocation induced by these irradiation was detected and bred in the pedigrees of irradiated materials by the selection in terms of the partial sterility of seeds. The examination of seed fertility and chromosome pairing at the MI of meiosis of the F/sub 1/ hybrid between the selected lines and the original cultivar was also used. Consequently, 50 homozygous lines of reciprocal translocation were confirmed. The tester lines for translocated chromosomes were established by the cytological examination of the chromosome pairing in the hybrids between each two of the tester lines. The investigation of the inheritance of translocation heterozygotes showed that most of the newly obtained lines differently behaved from the expectation on the genetical basis of reciprocal translocation.

1984-01-01

On the cables used for nuclear power stations, in particular those ranked as IE class, flame retardation test, simulated LOCA environment test, radiation resistance test and so on are imposed. The results of the evaluation of performance by these tests largely depend on the insulating materials mainly made of polymers. Ethylene propylene copolymer rubber has been widely used as cable insulator because of its electrical characteristics, workability, economy and relatively good radiation resistance, but it is combustible, therefore, in the practical use, it is necessary to make it fire resistant. The author et al. have advanced the research on the molecular design of new fire retarding materials, and successfully developed acenaphthylene bromide condensate, which is not only fire resistant but also effective for improving radiation resistance. The condition of flame retardant, radiation resistant auxiliary agents is explained, and there are additive type and reaction type in fire retarding materials. The synthesis of acenaphthylene bromide condensate and its effect of giving flame retardant and radiation resistant properties are reported. The characteristics of the cables insulated with the flame retardant ethylene propylene rubber containing acenaphthylene bromide condensate were tested, and the results are shown. (Kako, I.).

Dynamics of high energy reactions

During last several years, a new framework to describe strong interaction physics has emerged, i.e. quantum chromodynamics (QCD). It is the simplest field theory which incorporates color-dependent force among quarks. This force is generated by the exchange of colored vector gluons coupled to the quarks in gauge-invariant manner. The theory is closely related to the most successful quantum field theory, QED, and the only but very important difference is the gauge group involved. Although the theory is well defined, precisely what it predicts is not yet clearly known. However, at very high energy or momentum transfer Q, the effective coupling between quarks and gluons decreases toward zero with increasing Q 2 , and the calculation of a process involving high Q 2 is possible by the use of perturbation theory. In this paper, many applications of QCD to the processes involving high momentum transfer are examined. The effective coupling resulting from strong interaction between quarks and gluons, the scale violation in deep inelastic lepton scattering, large mass muon pair production, quark and gluon fragmentation functions, large transverse momentum meson and jet production in hadron-hadron collision, and the search for three-jet events are discussed.

The advanced thermal prototype reactor ''Fugen'' attained the criticality on March 20, 1978, and 100% output operation on November 13, 1978. On March 20, 1979, it passed the final inspection, and since then, it has continued the smooth operation up to now. The measuring and control equipments are provided for grasping the operational conditions of the plant and operating it safely and efficiently. At the time of designing, manufacturing and installing the measuring and control equipments for Fugen, it was required to clarify the requirements of the plant design, to secure the sufficient functions, and to improve the operational process, maintainability and the reliability and accuracy of the equipments. Many design guidelines and criteria were decided in order to coordinate the conditions among five manufacturers and give the unified state as one plant. The outline of the instrumentations for neutrons, radiation monitoring and process data, the control systems for reactivity, reactor output, pressure and water supply, the safety protection system, and the process computer are described. Finally, the installations and tests of the measuring and control equipments are explained. The aseismatic capability of the equipments was confirmed. (Kako, I.)

1983-01-01

The examples of the analysis of thermal stress in multiple connection regions such as heat exchangers, nuclear reactor cores, ingot cases and polygonal region with elliptic holes are not few, but the temperature dependence of material constants was neglected in these researches because of the difficulty of analysis though the industrial problems related to thermal stress are apt to occur in the condition of relatively large temperature gradient. Also, the analysis of heat conduction problems taking the temperature dependence of material constants into account was limited to one-dimensional problems for which Kirchhoff's transmission can be used. The purpose of this study is to derive the equation of condition which assures the one-value property of rotation and displacement, taking the temperature dependence of material constants into account, and to complete the formulation of the plane thermal stress problems in multiple connection regions by stress function method. Also the method of numerical analysis using difference method is shown to examine the effectiveness of various formulated equations and the effect of the temperature dependence of material constants on temperature and thermal stress. The example of numerical calculation on a thin rectangular plate with a rectangular hole is shown. (Kako, I.)

In Japanese nuclear power stations, owing to the improvement of fuel management, thorough maintenance and inspection, and the improvement of facilities, high capacity ratio has been attained. The thorough training of operators in nuclear power stations also contributes to it sufficiently. The BWR operator training center was established in 1971, and started the training of operators in April, 1974. As of the end of March, 1986, more than 1800 trainees completed training. At present, in the BWR operator training center, No.1 simulator of 800 MW class and No.2 simulator of 1100 MW class are operated for training. In this report, the method, by newly adopting it, good result was obtained, is described, that is, the method of introducing the feeling of being present on the spot into the place of training, and the new testing method introduced in retraining course. In the simulator training which is apt to place emphasis on a central control room, the method of stimulating trainees by playing the part of correspondence on the spot and heightening the training effect of multiple monitoring was tried, and the result was confirmed.

Recently in the field of scientific and technical calculation, the usefulness of supercomputers represented by CRAY-1 has been recognized, and they are utilized in various countries. The rapid computation of supercomputers is based on the function of vector computation. The authors investigated the adaptability to vector computation of about 40 typical atomic energy codes for the past six years. Based on the results of investigation, the adaptability of the function of vector computation that supercomputers have to atomic energy codes, the problem regarding the utilization and the future prospect are explained. The adaptability of individual calculation codes to vector computation is largely dependent on the algorithm and program structure used for the codes. The change to high speed by pipeline vector system, the investigation in the Japan Atomic Energy Research Institute and the results, and the examples of expressing the codes for atomic energy, environmental safety and nuclear fusion by vector are reported. The magnification of speed up for 40 examples was from 1.5 to 9.0. It can be said that the adaptability of supercomputers to atomic energy codes is fairly good. (Kako, I.)

The Nuclear Safety Commission reported to the Minister of International Trade and Industry on October 27, 1983, that the technical capability was recognized to be adequate, and the safety after the alteration of the installation of reactors was judged to be ensured. At the time of deliberation, the guidelines for examining the safety design and safety evaluation of LWR facilities for power generation were used. Regarding the change of the degree of enrichment of replacement fuel from 3.2 to 3.4 wt.%, the limiting conditions are satisfied in the replacement core, and the nuclear design is appropriate. Eight test fuel assemblies using UO 2 pellets containing gadolinia are charged in the core of No.2 reactor, and the irradiation of two cycles is carried out. As the result of the safety examination regarding this test, the propriety of the nuclear design and mechanical design of the test fuel assemblies was confirmed. This alteration does not exert influence on the result of safety analysis made so far. This report was decided by the Committee on Examination of Reactor Safety based on the conclusion of No.26 subcommittee. (Kako, I.)

The dialytic coefficient for hydrogen is especially large in palladium and its alloys. Recently, with the research on fusion reactors, the dialytic coefficient of tritium permeating through solids and its isotopic effect have been the object of interest. The ratio of the dialytic coefficients of tritium and hydrogen has been usually assumed to be 3. The measurement of the dialytic coefficient in solids using pure tritium is practically difficult. Therefore, the authors carried out the experiment to determine the ratio of the dialytic coefficients of pure T 2 and pure H 2 by permeating the mixed gas of T and H through Pd-Au-Ag alloy. The mixed hydrogen gas was filled in a separation cell containing a palladium alloy tube, and the separation factor of tritium and hydrogen was measured by changing pressure, flow rate and temperature. The separation factor depends mainly on the relative dialytic coefficients of tritium and hydrogen, therefore, the ratio of dialytic coefficients can be determined by the simple analysis of the experimental results. This experimental method is suitable to determine the relative value of dialytic coefficients, and the obtained ratio was about 2.1. (Kako, I.)

When the balanced downflow type condensers were adopted for actual plants, the construction, strength and production method were examined, and the reliability of the new condenser was confirmed by the thermal characteristic experiment with the model similar to the actual machine. The condenser comprises a condenser body, supporting plates, cooling tubes, tube plates, water chambers, and reinforcements, and the cooling tubes are arranged so as to exchange heat effectively. The arrangement of tubes is divided into three regions, namely radiation portion, densely arranged portion, and air cooling portion. In the balanced downflow type condensers, the dilution by utilizing condensate is provided against ammonia attack. The apparatuses for the thermal characteristic experiment and the experimental results, and the results of the performance test on the actual balanced downflow type condenser are reported.

Kajima, Ryoichi

1987-01-01

It is stipulated that nuclear power plants are to be built on solid rock bases on land in Japan. However, there are a limited number of appropriate siting grounds. The Central Research Institute of Electric Power Industry has engaged since 1981 in the studies on the construction technology of power plants, aiming at establishing new siting technology to expand the possible siting areas for nuclear power plants. Underground siting is regarded as a proven technology due to the experience in underground hydroelectric power plants. The technology of siting on quaternary ground is now at the stage of verification. In this report, the outline of floating type offshore/inshore siting technology is introduced, which is considered to be feasible in view of the technical and economical aspects. Three fixed structure types were selected, of which the foundations are fixed to seabed, plant superstructures are above sea surface, and which are floating type. Aiming at ensuring the aseismatic stability of the plant foundations, the construction technology is studied, and the structural concept omitting buoyancy is possible. The most practical water depth is not more than 20 m. The overall plant design, earthquake isolation effect and breakwater are described. (Kako, I.)

1987-01-01

In order to rationalize the aseismatic design of nuclear power stations, it is necessary to elucidate the characteristics of effective input when the earthquake motion for the design is inputted in the foundations of nuclear power stations. In this study, among the research subjects concerning the reduction of effective earthquake input, regarding the uplift of foundations, its response characteristics and the method of the rational evaluation of earth contact ratio were experimentally examined, and the method of analysis which can evaluate the damping effect due to the uplift was proposed. The experimental method is reported. It was found that accompanying the uplift of foundations, vertical motion was induced, and horizontal motion showed nonlinear response. It was confirmed that the nonlinear response accompanying the uplift can be approximately evaluated by the conventional analysis technique using the S-R model. The current equation for evaluating earth contact ratio is adequate for a soft ground model, and tends to undervaluate for a hard ground model. The S-R analysis model introducing the experimentally obtained characteristics in the dampling coefficient of a nonlinear rocking spring was newly made. (Kako, I.)
