Reactivity Coefficients in Large Fast Power Reactors. Harry H. Hummel, David Okrent. Item ID: | 1st Edition | pages. Recommend to My Librarian. This book introduces students, reactor physicists, and nuclear engineers to the literature and state-of-the-art of a subject of vital importance as the nuclear community becomes. Abstract. Several safety parameters are calculated for a large, fast, Na-cooled, oxide-fueled reactor. The Doppler coefficient is studied as regards its effect on the reactivity during a power excursion, and its dependence on the neutron spectrum, on the concentrations of U/sup /, Pu /sup /, a nd Pu/sup /, on spatial temperature and power distributions, and on temperature. @article{osti_, title = {PRELIMINARY REPORT ON SODIUM TEMPERATURE COEFFICIENTS IN LARGE FAST REACTORS}, author = {Nims, J B and Zweifel, P F}, abstractNote = {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. Book Review Reactivity Coefficients in Large Fast Power Reactors, by Harry H.

The Doppler effect has been important in the design and safety evaluation of projected large fast breeder reactors. In some systems under consideration, it is the largest contributor to the net power coefficient of reactivity, and an accurate knowledge of its magnitude is required in the design of the control and safety systems, in the evaluation of the steady-state and transient operating Cited by: 8. It explains the fast reactor temperature coefficients that differ in a number of respects from those of thermal reactors. The chapter examines reactivity control and the concepts of excess reactivity, temperature, and power defects. The chapter concludes with a discussion of reactor transients.   Power coefficient of reactivity. The change in reactivity per percent change in power. The power coefficient is the summation of the moderator temperature coefficient of reactivity, the fuel temperature coefficient of reactivity, and the void coefficient of reactivity.

Proceedings of the Conference on Breeding, economics and safety in large fast power reactors, October , [Alvin Glassner; U.S. Atomic Energy Commission.; Argonne National Laboratory.;] -- Fast reactors are gradually attaining a very prominent place in the research and development programs of reactor research centers throughout the world. Operation of the Phenix prototype fast reactor has resulted in 35 years of experience in controlling fast reactors. The self-stabilizing thermal feedbacks, the low spatial effects and the high. An Introduction to the Engineering of Fast Nuclear Reactors is a concise yet comprehensive introduction to all aspects of fast reactor engineering designed for both graduate-level engineering students and practicing nuclear engineers who want to expand their knowledge of fast Cited by: 3. power coefficient is thus expressed in moderator coefficient aP fT 1 k k Tc 1 k k = + 1 () 2Wcp 1 Rf + 2Wcp aP = Rfaf + (2Wcp)-1 (af + ac) • • Thus as power is increased positiveThus, as power is increased, positive reactivity is required to overcome negative coefficients and maintain criticalitycoefficients and maintain criticality.
