On Some Fundamental Peculiarities of the Traveling Wave Reactor [PDF]
Science and Technology of Nuclear Installations, 2015 On the basis of the condition for nuclear burning wave existence in the neutron-multiplying media (U-Pu and Th-U cycles) we show the possibility of surmounting the so-called dpa-parameter problem and suggest an algorithm of the optimal nuclear burning ...

Traveling waves in a bio-reactor model [PDF]
Nonlinear Analysis: Real World Applications, 2004 The existence of a family of traveling waves is established for a parabolic system modeling single species growth in a plug flow reactor. The proof uses phase plane analysis, geometric singular perturbation theory and the center manifold theorem.

Fast traveling-wave reactor of the channel type
Мiждисциплiнарнi дослiдження складних систем, 2017 The main aim of this paper is to solve the technological problems of the TWR based on the technical concept described in our priority of invention reference, which makes it impossible, in particular, for the fuel claddings damaging doses of fast neutrons to excess the ~200 dpa limit.

Boiling water cooled travelling wave reactor
Annals of Nuclear Energy, 2019 Abstract This study investigates the principal possibility of a boiling-water-cooled travelling wave reactor that can potentially improve the natural uranium utilisation in Boiling Water Reactors (BWRs), and more general in water-cooled reactors, appreciably.

Study of a distributed ICRF antenna system in DEMO
EPJ Web of Conferences, 2017 Different feeding options for distributed ICRF antenna systems in DEMO are analysed and compared, based on detailed circuit modelling. Voltages and currents (amplitude and phase) are computed for each element of the array.

Advanced Materials, EarlyView.This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Asymptotic Solutions of Serial Radial Fuel Shuffling
Energies, 2015 In this paper, the mechanism of traveling wave reactors (TWRs) is investigated from the mathematical physics point of view, in which a stationary fission wave is formed by radial fuel drifting. A two dimensional cylindrically symmetric core is considered
