Abstract
CE DISPOSITIF SIMPLE ET ROBUSTE, DE HAUTEUR RELATIVEMENT FAIBLE NE COMPREND QUE DEUX GRAPPINS ELEMENTAIRES SERVANT A SAISIR RESPECTIVEMENT LE BARREAU COMBUSTIBLE ET LES BARRES DE SERVICE A L'INTERIEUR DE CE DERNIER. A CET EFFET, LE BLOC TELESCOPIQUE SUSPENDU AU CABLE 11 COMPREND LE CARTER EXTERIEUR 7, PORTANT LE GRAPPIN AFFECTE AU BARREAU COMBUSTIBLE ET LE GRAPPIN INTERIEUR 9 AFFECTE AUX BARRES DE SERVICE. UN DISPOSITIF D'ENTRAINEMENT ET D'ACCOUPLEMENT 12 COMMANDE LE MOUVEMENT DES TAQUETS PIVOTANTS 60, DONT LA POSITION DETERMINE LA SOLIDARISATION OU LA LIBERATION DE LA COMMANDE DU GRAPPIN DES BARRES PAR RAPPORT AU CARTER SUSPENDU 7. CE GRAPPIN PEUT ETRE UTILISE A L'EXTRACTION DES BARREAUX COMBUSTIBLES ET DES BARRES DE SERVICE DE TOUT REACTEUR NUCLEAIRE.
