[en] World has become sensitive to the security of energy supply after experiencing oil crises and has given priority to the policies directed at developing alternatives to oil, notably coal, natural gas, and nuclear as well as encouraging rational use of energy and guiding the advent of new energy saving technologies. Nuclear energy is produced by the use of complicated technological facilities as well as uranium. Although immense technological effort was devoted before it has become widely used, the commercialization of this energy has opened a new way to assure stable supply of energy through the possession of technology, in addition to the classical way through the possession of natural resources. This is an important option to the countries like Japan which endowed almost no significant amount of natural energy resources except solar, use of which also depends on the progress in the related technology. Nuclear energy is considered as a semi-domestic source of energy in Japan and expected to account for growing share of total energy supply in coming years. Expecting that the 21st century will be a century of plutonium, technology bases for the stable nuclear energy supply system based on plutonium are under development. Prerequisite for the accomplishment of this role is the assurance of safety and public acceptance. Efforts are concentrated on further improvement of the plant technology, training and education of the personnel involved, and safety measures installed, without being content with the current excellent record of operation. Furthermore, a number of leading R and D projects are promoted aggressively with a view to pursue new possibility of nuclear energy. These R and D expected to bring about various spillover in other industries and lead the development of science and engineering in general
[en] The provisional data available indicate that Italy's total primary energy demand Increased in 1987 by 3.8% (see table 1) as compared to a GNP Increase in real terms of 2.7%. Oil and natural gas consumption registered a growth of 4% and 11.3% respectively compared to the 1986 levels. Primary electricity (hydro-geo and nuclear) decreased by 18% due essentially to a total lack of nuclear contribution. Net electricity import increased by 4.5%. It should be noted that the Italian energy dependence on external primary sources has continued at the very high level of 81% being the highest among the industrialized countries

[en] The Nuclear Industry is now over 40 years old and a proven, mature product has been developed. That proven mature product has evolve into a small set of standardized designs - designs based on evolution of the best and safest features, not revolutionary changes. Just as the product design must be standardized, the regulatory process must also be standardized. With a predictable regulatory environment and rate structure the economic advantages of Nuclear Power will be self-evident. The Nuclear Industry in the United States has had a history of cycles as the economy and need for power has changed. The need for electricity to support growth is a given. With a strong focus on the standardization of the process and the product, a competent engineering approach to safety, and improved economies, the 21st century will see nuclear power assume its appropriate role as a key source in the energy mix in the United States. Presenting a discussion dealing with the future is always a risky thing. One man's prognosis is another mans wild guess. Today, I would like to talk briefly on my views of the future, and especially my views on the Prospects for Nuclear Energy in the U. S. in that future. Though it is clear that nuclear energy will play a key role in fulfilling the energy needs of the world, the future of nuclear energy in the United States is not as clear. A discussion of the future of the U. S. Nuclear Industry is especially appropriate here today because I am firmly confident that the Republic of Korea will play a major role in that future. The world energy situation and the role of nuclear power has undergone a number of upsets in the last decade. Often we tend to dwell on the gloom of the past and overlook the strengths that the Nuclear Industry has developed. Presently over 437 gigawatts of electricity in the world is planned to be produced by 564 nuclear units. There are over 32 countries with commercial nuclear programs. One of the brightest of these being here in Korea. The Korean program has managed to move forward aggressively where other programs have become mired down
[en] These studies are about electric power in seven fields, which are computerized system of electric facility management research on dismantling nuclear power plant, development of reasonable operation program in hydroelectric power plant, an empirical study on saving of mineral energy and a case study, redaction measures of nitrogen oxides, nondestructive testing of concrete and research of penetration rate of appliances.
[en] This analysis is part of the report on ' Implementation of geometry module of 05R code in another Monte Carlo code', chapter 6.0: establishment of future activity related to geometry in Monte Carlo method. The introduction points out some problems in solving complex three-dimensional models which induce the need for developing more efficient geometry modules in Monte Carlo calculations. Second part include formulation of the problem and geometry module. Two fundamental questions to be solved are defined: (1) for a given point, it is necessary to determine material region or boundary where it belongs, and (2) for a given direction, all cross section points with material regions should be determined. Third part deals with possible connection with Monte Carlo calculations for computer simulation of geometry objects. R-function theory enables creation of geometry module base on the same logic (complex regions are constructed by elementary regions sets operations) as well as construction geometry codes. R-functions can efficiently replace functions of three-value logic in all significant models. They are even more appropriate for application since three-value logic is not typical for digital computers which operate in two-value logic. This shows that there is a need for work in this field. It is shown that there is a possibility to develop interactive code for computer modeling of geometry objects in parallel with development of geometry module
[sr]Ova analiza predstavlja deo izvestaja a radu na zadatku UGRADNJA GEOMETIRJSKOG MODULA PROGRAMA 05R U DRUGI MONTE CARLO PROGRAM, tacka 6.0: Utvrdjivanje pravca daljeg rada na pitanjima geometrije u Monte Carlo metodi. U uvodnom delu izvestaja ukazano je na neke probleme u toku resavanju slozenih trodimenzionih modela iz kojih proistice potreba za razvojem efikasnijih geometrijskih moduIa u Monte Carlo proracunima. Drugi deo sadrzi formulaciju problema i geometrijskog modela. U okviru toga definisana su dva osnovna pitanja koje treba resiti: (1) za datu tacku treba odrediti materijalnu zonu ili granicu kojoj ta tacka pripada i (2) za dati pravac odrediti sve tacke preseka sa granicama materijalnih zona modela. Treci deo razmatra mogucnost sprege Monte Carlo proracuna sa programima za kompjutersko modeliranje geometrijskih objekata. Teorija R-funkcija omogucava izradu geometrijskog modula koji bi se bazirao na istoj filozofiji (slozene oblasti se konstruisu pomocu elementarnih oblasti i operacija sa skupovima) kao i programi konstruktivne gecmetrije. R-funkcije mogu efikasno da zamene funkcije troznacne logike u svim kljucnim pitanjima modeliranja. Stavise one su pogodnije za primenu jer troznacna logika nije svojstvena digitalnim racunarima, vec se obavlja pomocu vise operacija dvoznacne logike. Prednosti primene R-funkcija sumirane su u zakljucku, gde se ukazuje da postoji kako potreba tako i znacajna osnova za rad na ovoj problematici. Pored toga, ukazano je da paralelno sa razvojem geometrijskog modula moze da se radi i na razvoju interaktivnog programa za kompjutersko modeliran]e geometrljsklh objekata. (author)
[en] India’s Gross National Product, growth rate during 1987-88 has been about 1.8%, while the industrial growth rate was about 10%. The low GNP growth rate compared to the earlier years is due to severe drought the country had to face due to failure of monsoon. The import of oil during 87-88 was 18.6 million tonnes and caused a heavy burden on foreign exchange. The hydel power generation was low due to failure of rains. However, this has been partly made up by improved capacity factors of the coal based thermal power plants. The average plant load factor (PLF) in the country improved markedly to 56.4%. Some of the coal based thermal plants achieved PLFs over 75%. Four 500 MWe coal based thermal power stations have been commissioned during 87-88. About 1200 Km out of 1750 Km, of underground gas pipeline, Hazira-Bijapur- Jagadispur, has been commissioned for transporting gas for fertiliser and power plants. Encouraging results are being achieved for oil exploration in Cauvery, Krishna and Godavari basins
[en] Nuclear energy in the United States has made major contributions since the small Shippingport prototype power plant began operating in 1957. Recent legislative and regulatory actions, as well as research an development, are indicating that additional nuclear capacity can be available in the years ahead. These actions reflect the public's recognition of the importance of nuclear energy. In addition, recent regulatory actions are reaffirming the health and safety of our current nuclear plants, as well as of those being completed. The performance of our current plants is being improved through the conscious dedication of the entire industry to excellence. There is increasing discussion in the United States of the importance of advanced reactor concepts development. The next generation of nuclear plants is already being ordered outside of the United States for example, here in Korea, in Japan, in the United Kingdom and those plants all use light water reactors. We are pleased that U. S. companies are working with you on these new plants. That continues to mean that we never let up on our drive for excellence. Excellence in operations must continue to be the conscious target of all operators. Excellence in communications to the public of the need for electrical capacity, of the benefits of nuclear energy, and of the excellence being achieved in operations is also essential. And excellence in communication to decision makers at all levels of government is also required to assure that sound legalisation and regulation is established and implemented
