Abstract

Un reattore nucleare a acqua pressurizzata impiega il suo impianto di rimozione di calore residuo per integrare acqua nel circuito refrigerante del reattore da una alimentazione d'acqua di rifornimento nel contenimento durante depressurizzazione e stadi portante a raffreddamento di emergenza passivo mediante alimentazione a gravità del serbatoio di immagazzinamento dell'acqua di rifornimento e allagamento dell'edificio di contenimento. Quando depressurizzazione inizia a causa di una perdita occidentale o controllabile, il sistema o impianto di rimozione di calore residuo viene attivato manualmente e impedisce allagamento del contenimento quando tale azione non è necessaria. Il funzionamento del sistema o impianto di raffreddamento passivo non è compromesso. Un serbatoio di immagazzinamento d'acqua di integrazione ad alta pressione è collegato al circuito refrigerante del reattore mantenendo refrigerante di integrazione o rincalzo alla pressione di funzionamento del reattore. Il sistema o impianto di depressurizzazione a stadi sfoga il circuito del refrigerante al contenimento, riducendo così l'alimentazione di refrigerante di integrazione. Il livello di refrigerante di integrazione può essere rilevato per innescare l'apertura di condotti di depressurizzazione successivi. Le pompe di rimozione del calore residuo spostano acqua del serbatoio di immagazzinamento dell'acqua di rifornimento nel circuito del refrigerante quando il circuito del refrigerante è depressurizzato, impedendo di raggiungere lo stadio di depressurizzazione finale a meno che il livello del refrigerante di integrazione non continui a diminuire. Il sistema di rimozione di calore residuo può pure essere collegato in un ciclo chiuso o anello con il serbatoio d'alimentazione dell'acqua di rifornimento o ricarica per un percorso di rimozione del calore ausiliare.
