Abstract
L'indicatore di otturazione permette la misura in continuo della purezza del sodio che circola nei circuiti di un reattore a neutroni veloci senza richiedere smontaggio o sostituzione completa dell'indicatore, in caso di otturazione della sezione di misura.Comprende principalmente una conduttura di derivazione comprendente una parte esterna (8) ed una parte interna (9) coassiali. Una testa di misura (10) è montata mobile tra queste due parti ed è composta principalmente da almeno una termocoppia (24) e da una griglia (22) mobile che fa variare la sezione di misura ed anche la portata misurata, per favorire le disotturazioni e la dissoluzione delle impurezze cristallizzate durante le misure. Questo gruppo è completato da altri elementi principali dell'indicatore di otturazione in un corpo longitudinale allungato, e circondato da uno scambiatore termico (11) per il raffreddamento del sodio.(Figura 1).
