Book Proceedings of the Conference on Breeding Economics and Safety in Large Fast Power Reactors October 7 10 1963

Download or read book Proceedings of the Conference on Breeding Economics and Safety in Large Fast Power Reactors October 7 10 1963 written by Alvin Glassner and published by . This book was released on 1963 with total page 938 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fast reactors are gradually attaining a very prominent place in the research and development programs of reactor research centers throughout the world. It is appropriate, therefore, that international conferences be held periodically to foster direct communication among fast reactor specialists. Subject-wise, this first conference was limited to the topics of breeding, economics, and safety of large fast reactors, with particular emphasis on the interrelation among them. Many other topics remain to be covered in future meetings.

Book Some Physics Calculations on the Performance of Large Fast Breeder Power Reactors

Download or read book Some Physics Calculations on the Performance of Large Fast Breeder Power Reactors written by S. Yiftah and published by . This book was released on 1960 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical mass, spectrum, breeding ratio, and coolant removal coefficients were calculated for a series of large Pu-U238-fueled sodium-cooled fast-breeder power reactors, using a new 16-group cross-section set based in part on recent microscopic cross-section measurements. The parameters studied include reactor size, plutonium isotopic content, and type of structural material. Reactors cooled with Pb-Bi eutectic and those containing U233-Th fuel were examined.

Book PRELIMINARY REPORT ON SODIUM TEMPERATURE COEFFICIENTS IN LARGE FAST REACTORS

Download or read book PRELIMINARY REPORT ON SODIUM TEMPERATURE COEFFICIENTS IN LARGE FAST REACTORS written by and published by . This book was released on 1959 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Present practice in fast reactor design is to eliminate any known positive temperature coefficients of reactivity. This approach has been feasible for the fast power reactors now being constructed. In recent considerations of advanced fast reactor designs at APDA, some cases were encountered in which the sodium temperature coefficient of reactivity was positive. Because of the serious implications of this result. a study of the sodium temperature coefficient of a design in which the problem appears to be most severe was made. The principle objective of the study was to obtain a better understanding of the problem. Simply stated, reducing the sodium density causes spectral reactivity effects which can, in some situations, be positive and larger in magnitude than the negative leakage effect, thereby causing a positive temperature coefficient of reactivity. In addition. some attention was also given to possible methods of influencing the sign of the sodium coefficient. Although the results indicate that these methods couid be successfully applied. there are penalties involved with their use. The results given are believed to be quaiitatively correct, but the uncertainties in the cross section data on which they are based cast some doubt on the quantitative accuracy. (auth).

Book A STATUS REPORT ON REACTIVITY COEFFICIENTS IN FAST REACTORS AND METHODS OF INVESTIGATING THEIR EFFECTS ON REACTOR STABILITY

Download or read book A STATUS REPORT ON REACTIVITY COEFFICIENTS IN FAST REACTORS AND METHODS OF INVESTIGATING THEIR EFFECTS ON REACTOR STABILITY written by and published by . This book was released on 1961 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BS>Methods for predicting the stability of fast reactors in the presence of both positive and negative reactivity coefficients are surveyed. Experimental methods of determining reactor stability are reviewed: excursion, transient, and oscillator. Sources of reactivity coefficients are discussed for both zero power and nonzero power operation. Representative reactivity coefficient values are presented, and positive coefficients due to Doppler effect, fuel bowing, and sodium coolant expansion are discussed. (D.L.C.).

Book Current Status of Fast Reactor Physics

Download or read book Current Status of Fast Reactor Physics written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of calculation of reactivity coefficients for fast reactors is developed, starting with a discussion of the status of relevant nuclear data and proceeding to the subjects of group cross section generation and of methods of obtaining reactivity coefficients from group cross sections. Reactivity coefficients measured in critical experiments are compared with calculated values. Dependence of reactivity coefficients on reactor design is discussed. Finally, results of the recent international comparison of calculated reactivity coefficients are presented.

Book Status of Fast Reactor Research and Technology Development

Download or read book Status of Fast Reactor Research and Technology Development written by International Atomic Energy Agency and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Based on a recommendation from the Technical Working Group on Fast Reactors, this publication is a regular update of previous publications on fast reactor technology. The publication provides comprehensive and detailed information on the technology of fast neutron reactors. The focus is on practical issues that are useful to engineers, scientists, managers, university students and professors. The main issues of discussion are experience in design, construction, operation and decommissioning, various areas of research and development, engineering, safety and national strategies, and public acceptance of fast reactors. In the summary the reader will find national strategies, international initiatives on innovative (i.e. Generation IV) systems and an assessment of public acceptance as related to fast reactors."--Résumé de l'éditeur.
