An explicit Runge-Kutta type method for systems of ordinary differential equations with special structure is considered. For partitioned a family methods order six just stages constructed, which makes them more efficient than classic six. It shown that second equations, right-hand side doesn't depend on the first derivative, can be rewritten as considered systems. Direct application constructed to generates two different families Runge-Kutta-Nyström methods. The comparison known held.
Neutronics and thermal physics studies of BN-VT reactor installation with 600-MW power demonstrated the possibility in principle to achieve required parameters high-temperature fast for production large quantities hydrogen on basis, instance, one chemical cycles or hydrolysis high efficiency use electric power. Relatively small dimensions, type coolant, selection fissile material structural materials allow developing nuclear particular inherent properties (exclusion prompt-neutron...
The presented results of neutron-physical, thermophysical, and technological studies have shown that it is possible in principle to provide the required parameters a high-temperature (900-950 °C) reactor installation with 600 MW (heat) sodium coolant for hydrogen production other innovative applications based on one thermochemical cycles or high temperature electrolysis coefficient thermal use electricity. relative small size, type coolant, choice fissile material structural materials make...
One of the main issues in using materials for nuclear facilities is to minimize production most hazardous radionuclides. In ideal case, all reactor materials, except a fuel, should be low-activation. The term “low-activation material” means that this one loses its induced activity short time after removal from irradiation. Proposals building fusion low-activation are given Ref.1, 2. For purpose, structural based on V-Ti-Cr alloys stage R&D several countries [3,4]. Another technique avoid...
The Cornell Electron Storage Ring (CESR) operates as an electron-positron collider with 9 trains of 2 to 5 closely spaced bunches per train beam. Linac is the initial component injector for CESR and it needs provide multibunch electrons positrons at high injection rates CESR. This paper presents results simulations which have studied effects operating currents needed production positron bunches. Results include effect longitudinal wakefields induced by beam in linac prebuncher cavities a...
Long-term scenarios of nuclear energy evolution over the world scale predict deployment fast reactors (FRs) from 2020–2030 and achievement near 2050 installed capacity equal to 1500 GWe with essential increasing FRs number. For several countries (i.e. Russia, Japan) which policies are based on a sharp increase production, at stage 2030–2040 when plutonium, Pu, PWR spent fuel is consumed, Pu lack will stimulate minimizing its loading in FRs. The period deficiency be prolonged till years...
In the paper a possibility of using isotopic tailored chemical elements in functional materials Accelerator Driven Systems (ADSs), structural Fast Reactor (FR) cores and matrix uranium free fuels is considered. The first subject possible usage lead enriched with isotopes, ^<206>Pb or ^<208>Pb, as liquid coolant ADSs FRs. Lead low activation, ^<210>Po ^<207>Bi free, 'pure' ^<208>Pb an ideal moderating absorbing neutrons material for coolant. second dedicated to nickel depleted isotope ^<58>Ni...
