Abstract

As a complement of the IPSS - BWR R&D Cluster project the BWR - Physics and Thermalhydraulics Complementary Actions (BWRCA project) contributed to answer issues which are identified for the future BWR plants: - the design of innovative components; - an enlarged assessment of the performances; - a better understanding of the underlying physical phenomena both thermalhydraulics and neutronics. Following the first two objectives, three systems have been assessed: -the Thermal Valve device (TV) which is of interest for the systems using in-pool beat exchangers; - the Emergency Condenser and o the Building condenser, already studied as tasks of the IPSS - BWR R&D Cluster, for the Passive Decay Heat Removal respectively from the Core Region and from the Containment. The third objective intended to reduce the current uncertainties in BWR dynamic behaviour by performing coupled thermalhydraulics and reactor kinetics computer simulations of the natural circulation cooled Dodewaard reactor, and distributing the available experimental data from the Dodewaard reactor and the DESIRE flow loop.
