Perfecting a control rod with a diving-bell

Creators

Description

A degassed control rod last longer because helium produced is eliminated avoiding pressure in the rod producing mechanical stress. Seven tests were carried out, at Interatom for testing the diving bell principle without irradiation: 5 in still sodium, one in flowing sodium and one in water. All the tests have confirmed the reliability of the system: control rod + diving bell

Abstract (French)

La barre de commande degazee offre l'avantage d'une duree de vie plus longue, car elle laisse echapper l'helium qui apparait et empeche ainsi une montee en pression dans la barre, qui y cree une sollicitation mecanique. On a effectue, a INTERATOM, 7 groupes d'essais afin de mettre a l'epreuve le concept de cloche plongeuse (sans irradiation), dont: - 5 dans le sodium au repos, - un essai d'arret rapide dans le sodium en ecoulement, - un essai en faisceau dans l'eau. Tous les essais ont confirme la fiabilite de fonctionnement du systeme: barre de commande + cloche plongeuse
