Collection and Review of VVER Transient Measurement Data

Technical Reports on VVER transients were provided by IVO, NRI, KI, STCNRS and INRNE. The present report gives a survey of the transients documented by the five organisations mentioned. The main actions and effects observed during each transient are briefly described. An overview of the information contained in the five Technical Reports is provided in tabular form. The tables comprise information on the initial states, the measured parameters, and the time regime of the measurement. For each reactor type, VVER­440 and VVER­1000, respectively, one transient is recommended for coupled codes validation in the current project.
