FRAMATOME RCVS Concept and Physics

摘要

We have tried through this presentation to emphasize on what FRAMATOME thinks to be the most specific problems of the advanced RCVS (Reactor core with spectral shift) core concept (Spectral shift, voidage, reactivity control). Besides, FRAMATOME is analysing the most important safety related topics typically LOCA and DNBR, and has launched developments on them, in connection with CEA. The core behaviour during a loss of Coolant Accident is quite similar to PWR's, the pitch between rods being sufficiently large for clad ballooning not to cause any damage. To conclude, the core improvements developed by FRAMATOME on the RCVS concept economize the use of fissile materials. (ERA citation 13:018184)
