Abstract

The second Egyptian research reactor ET-RR-2, is a pool type reactor. A sudden loss of pool water would leave the core region uncovered. The reactor core is surrounded by chimney chambers with water isolated from the pool water. This accident would lead to significant external doses. A model is developed and used to calculate the dose rates for key access-areas and traffic plans from indirect line of sight of the core which have a maximum dose rate. The model developed uses the discrete ordinate method as implemented in the code DOT3.5.

Abstract

Der zweite ägyptische Forschungsreaktor ET-RR-2 ist ein Reaktor vom Pool-Typ, bei dem der plötzliche Verlust des Wassers im Pool den Reaktorkern unbedeckt lassen würde. Der Reaktorkern ist umgeben von Kammern, deren Wasser vom Pool-Wasser getrennt ist. Ein solcher Unfall würde zu einer erheblichen Strahlendosis führen. Ein Modell wurde entwickelt und angewendet zur Berechnung der Dosisleistungen für die Hauptzugangswege.

Das entwickelte Modell verwendet die Methode der diskreten Ordinaten, die auch im Programm-Code DOT3.5 verwendet wird.
