An ex-vessel steam explosion may occur if the primary system is breached by hot debris. Debris in the reactor outlet piping may fail the piping and fall onto the pump room floor or debris on the reactor vessel bottom may be blocked from flowing into the outlet piping if it freezes in the effluent piping nozzle muff structure. If this occurs, the debris will heat up on the reactor vessel bottom and eventually fail the bottom shield. The likely mode of failure of the bottom shield is collapse of the shield as a whole. If it collapses, the entire shield, as well as the molten debris, will fall into the pin room below the reactor vessel. The debris will then flow across the floor into the pump room. In either event, a large portion of the reactor fuel inventory will be deposited on the pump room floor. The pump room floor will be covered with water in many scenarios. A steam explosion may result when the debris enters this water. 1, record 1, English, - ex%2Dvessel%20explosion

La condition nécessaire à une explosion vapeur est le simple contact entre les deux fluides, mais les situations les plus énergétiques sont celles où les deux fluides sont mélangés avant que ne se déclenche la fragmentation. Dans les réacteurs à eau pressurisée de tels mélanges pourraient se former après la fusion du cœur lors de la relocalisation du corium en fond de cuve (explosion en cuve) et/ou éventuellement lors de la percée de la cuve et la chute du corium dans le puits de cuve (explosion hors cuve). 1, record 1, French, - explosion%20hors%20cuve

For an operator, the accident simulation functionality could be used in a different way, to test several operating strategies and define the most efficient regarding core dewatering for instance. It could be used as well to assess the necessary water flow to be injected into the reactor coolant system to avoid core dewatering or if heat removal is sufficient to avoid core heat up. 1, record 2, English, - core%20dewatering

Record number: 3, Textual support number: 2 CONT
Besides aerobic biological treatment and mechanical separation processes, anaerobic treatment becomes more and more important in the purification of liquid waste with high organic load. The search for an economic treatment procedure leads to a two-stage anaerobic-aerobic treatment concept. Aerobic secondary treatment is required because the purification capacity will not be sufficient with anaerobic treatment only. Comparing two different anaerobic procedures, suitability, advantages and disadvantages can be determined. These procedures are the anaerobic contact sludge procedure(digester) and the up-flow reactor(UASB). The following aerobic stages are identical, they consist of activated sludge tank and final sedimentation tank with separate return sludge flow. 4, record 3, English, - up%2Dflow%20reactor

La granulation a été examinée dans un réacteur anaérobie à flux ascendant avec une couverture de boue (UASB, Upflow Anaerobic Sludge Blanket), à une température ambiante de 21,8° C. Des eaux d'égouts de brasseries, avec une demande chimique en oxygène (DOC) moyenne de 2030 mg/l et une demande en oxygène biochimique de 1150 mg/l, furent utilisées comme substrat et de la boue anaérobie digérée comme inoculum. 1, record 3, French, - r%C3%A9acteur%20ana%C3%A9robie%20%C3%A0%20flux%20ascendant
