A detailed analysis of the course of Transients in Nuclear Power Plants aims at both the establishment of effective and reliable control procedures and the optimisation of recovery procedures. For this, information in the form of measured data is needed. For Light Water Reactors, data has become available in the past from both reactor start-up and shut-down transients and from Transients experiments with the LOFT and Semiscale test facilities of the USNRC. The Member States of the European Communities (E.C.) recognise the need for additional experimental data and have requested that a Transients experimental programme be performed with the integral system LOBI test facility of the Commission of the E.C. at its Ispra Establishment.
