Description

Gegenstand des Hauptpatentes ist ein heterogener Kernreaktor mit Führungsrohren zur Aufnahme der Brennelemente, an deren Kühlmittelaustrittsende eine durch die Lademaschine betätigbare Brennelementsperre angeordnet ist.The subject of the main patent is a heterogeneous nuclear reactor with guide tubes for receiving the Fuel assemblies, at the coolant outlet end of which a fuel assembly lock that can be actuated by the loading machine is arranged.

Diese Einrichtung gewährleistet nur dann ein einwandfreies Funktionieren des Auswechselmechanismus der Brennelemente, wenn die äußere Gestalt der Brennelemente entsprechend ausgebildet ist (s. Anspruch 6 des Hauptpatentes).This device only guarantees the proper functioning of the replacement mechanism of the fuel assemblies if the external shape of the fuel assemblies is designed accordingly (see claim 6 of the main patent).

Die Brennelemente bestehen aus einer Stabhalterplatte (Lochplatte), die die einzelnen Brennstäbe trägt, und einem äußeren Leitrohr, dessen unterer Rand eingezogen ist.The fuel assemblies consist of a rod holder plate (perforated plate) that carries the individual fuel rods, and an outer guide tube, the lower edge of which is retracted.

Vorliegende Zusatzeriindung erweitert die Ausbildung dieses Brennelementes, um den Kühlmitteldurchfluß zu erleichtern und zu verbessern. Erfindungsgemäß wird der eingezogene untere Rand des äußeren Leitrohres des Brennelementes mit Bohrungen zum besseren Durchtritt der Kühlmittelströmung versehen.The present additional invention extends the training this fuel assembly to facilitate and improve the coolant flow. According to the invention is the retracted lower edge of the outer guide tube of the fuel assembly with holes for Provide better passage of the coolant flow.

Diese besondere Einrichtung ist außerdem deswegen erforderlich, um den Druckabfall an der aufschwimmbaren Drossel 5 in Fig. 1 des Hauptpatentes so groß als möglich zu machen. Je nach der Größe des Brennelementes kann es zweckmäßig erscheinen, den verhältnismäßig dünnen Rand des äußeren Leitrohres aus Festigkeitsgründen durch einen stabil gehaltenen und mit dem zylindrischen Teil dieses Leitrohres z. B. durch Schweißung fest verbundenen, ebenfalls mit Bohrungen versehenen Stützring aus ähnlichem oder gleichem Material zu ersetzen. Eine derartige Anordnung kann nicht nur aus festigkeitsmäßigen, sondern eventuell auch aus fertigungstechnischen Gründen zweckmäßig sein, wobei an die Beanspruchung durch die einrastenden Sperrklinken und durch das Aufeinandersetzen der einzelnen Spaltstoffelemente gedacht ist. Selbstverständlich können an Stelle der Bohrungen auch anders geformte Öffnungen treten, wie z. B. Schlitze. Letzteren ist unter Umständen der Vorzug zu geben, da sie sich schnell und leicht einfräsen lassen (der untere Rand des Stützringes muß dann nicht unbedingt geschlossen sein).This particular device is also required to reduce the pressure drop across the float To make throttle 5 in Fig. 1 of the main patent as large as possible. Depending on the size of the fuel assembly it may seem appropriate to use the relatively thin edge of the outer guide tube Strength reasons by a stable and held with the cylindrical part of this guide tube z. B. by welding firmly connected, also provided with holes support ring made of similar or the same Replace material. Such an arrangement can not only be based on strength, but possibly also be expedient for manufacturing reasons, taking into account the stress caused by the locking pawls and by putting them on top of each other the individual fissile material elements is intended. Of course, instead of the holes also occur differently shaped openings, such. B. Slots. The latter may be preferred because they can be milled in quickly and easily (the lower edge of the support ring then does not necessarily have to be be closed).
