| Popis: |
The physics and regularities of the neutron-thermoacoustic instability (NTAI) in nuclear channels with subcooled nucleate boiling flows are explained. The method for obtaining the characteristic equation of NTAI in a VVER-type reactor is given. The influence of steam reactivity coefficient ∂k/∂φ on NTAI boundaries is studied and the effect of a negative ∂k/∂φ favouring the oscillatory instability of neutron flux and pressure is shown. |
