Description
The initial events considered were a long-term outage of the main coolant system, power failure, primary coolant circuit leakages, and steam generator heating tube, leakage. The relevant consequences are practically nothing but the remobilisation of fission products which have deposited at the primary coolant circuit surfaces during normal operation. The most frequent case was response of the primary coolant circuit pressure relief valve. Pressure drops in the primary coolant circuit may also be a consequence of steam generator heating tube failures causing an incident. (DG)
Abstract (German)
Als ausloesende Ereignisse wurden der langfristige Ausfall des Hauptkuehlsystems, der Notstromfall, Lecks im Primaerkreislauf sowie ein Leck im Dampferzeuger-Heizrohr beim HTR-Modul analysiert. Die relevanten Folgen von Spaltprodukten, die sich im Normalbetrieb auf Primaerkreislaufoberflaechen abgelagert haben. Als haeufigster Fall erwies sich das Ansprechen des Primaerkreis-Druckbegrenzungsventils. Druckentlastungen des Primaerkreislaufs koennen auch eine Folge stoerfallausloesender Dampferzeuger-Heizrohrschaeden sein. (DG)Additional details
