【 摘 要 】

In the framework of the Fast Reactor R&D programme, an experimental electromagnetic (EM) induction pump has been designed with similar magnetohydrodynamic (MHD) characteristics to those expected for the secondary cooling system. This pump will provide us with experimental results that are needed to validate the numerical models used for the preliminary design 2, with the main objective being to develop and qualify a finite-element model of MHD instabilities of Annular Linear Induction Pump (ALIP). This paper describes the current status of the experimental and numerical analysis carried out to detect and investigate liquid sodium flow instabilities in the innovative ALIP, installed in the PEMDYN loop with the objective of better managing the EM pump and preventing MHD instability. In this paper we present the experimental results collected during the operation of the test campaign aiming establishing at performance maps of the high flowrate ALIP. It also describes the numerical finite-element models that have been built to gain a more in-depth understanding of the interdependent MHD phenomena 1.
