METHOD FOR CONTROLLED INTERMITTENT FEED OF TRITIUM IN TOKAMAK

摘要

FIELD: nuclear fusion; energy generation in magnetic traps of tokamak type. SUBSTANCE: tritium is fed to tokamak chamber due to its separation from gas absorbers combined in groups of N/k gas absorbers (k≥2, N is quantity of gas absorbers in tritium generator) in each k-th group as a result of their parallel connection by sequential connection of groups of N/k gas absorbers to impulse power supply raising its voltage up to ultimate destruction of gas absorbers; first pulse voltage corresponds to low value of required gas quantity range and next pulses are chosen according to recurrence formula including voltages of two preceding pulses and amounts of separated tritium in these pulses, as well as values of empirical function determined at constant voltage of pulses for each feed during service life of group of gas absorbers. EFFECT: improved stability at controlled intermittent tritium feed to tokamak.
