Axial offset as measure of stability of light water nuclear reactor during capacity maneuvering

High reliability and security of power unit are required during operation of power unit while maneuvering.They depend on the stability of reactor when transition from one power bolia outlet gent level to another.The axial offset is a quantitative measure of the reactor stability.It is shown that change of the active core inlet coolant temperature yields an uncontrollable disturbance affecting the axial offset and therefore the reactor stability.

To insure the reactor stability the compromise-combined power control method is proposed.Analysis of the influence of temperature of coolant at the magnitude of the axial offset for different regulatory programs is carried out.The change in the depth of immersion of regulators in the active Jeans zone for different regulatory programs when the reactor plant daily capacity maneuver is studied.
