Description

Determination of the two-phase flow (critical or otherwise) through a pump is an essential requirement for complete description of a loss of primary coolant accident in a PWR plant. Theoretical and experimental research at Electricite de France on this subject is described and problems associated with the introduction of a two-phase fluid (with mass transfer) are discussed, with an attempt to single out new phenomena involved and establish their effect on pump behavior. A complementary experimental investigation is described and the results of tests at pressures and temperatures up to 120 bars and 3200C respectively are compared with the theoretical model data

Abstract (French)

La determination du debit diphasique (critique ou non) au travers d'une pompe est un element essentiel pour la description complete d'un accident de perte de refrigerant primaire dans un reacteur PWR. Cet article presente les recherches theoriques et experimentales menees sur ce sujet a E.D.F. On examine les problemes poses par l'introduction d'un fluide a 2 phases (avec echange de masse) et on essaye de preciser quels sont les phenomenes nouveaux qui apparaissent et leurs influences sur le comportement de la pompe. Une etude experimentale vient completer cette recherche theorique et on presente une comparaison entre la modelisation et les resultats experimentaux en eau-vapeur dans un domaine allant jusqu'a 120 bars et 3200C
