Methodology for forming the VVER reactor parameter requirements in cycling power reactor tests

Abstract

The work was carried out as part of the computational and experimental justification of the operability of U and U‑Gd fuel rods of the VVER reactor in cycling power operating modes as part of the process of licensing domestically-produced fuel according to the requirements of Russian and foreign supervisory authorities. A methodology for forming the requirements for the rate of change in the local linear power of VVER reactors during tests in the research reactor simulating the cycling mode was developed.
