Abstract

The device used comprises one or more vertical arms carrying sensors oriented in a cross-sectional plane of the fuel element casing. These vertical arms can be moved longitudinally, parallel to the ideal side faces of the casing in steps, so that a succession of cross-sections can be measured. There are three sensors on each side of the casing, one at the mid-height and the other two located at points just at the corner radii. Used for checking fuel element casings e.g. of 3-5.5m length, where high accuracy in cross-section dimensions, e.g. of plus-or-minus 0.12 mm is required. Rapid surveying of the casings is possible with this device.

Die Anforderungen an die Maßhaltigkeit von Brennelementkästen, d.h. die Hüllkästen für die Brennelemente eines Kernreaktors, sind äußerst hoch. Die Toleranzen betragen beispielsweise nur + 0,12 mm, wobei sie Uber die ganze Länge, die in der Regel 3 - 5,5 m beträgt, garantiert werden mUssen.The requirements for the dimensional accuracy of fuel assembly boxes, i.e. the cladding boxes for the fuel elements of a nuclear reactor are extremely high. the Tolerances are, for example, only + 0.12 mm, whereby they are over the entire length, which is usually 3 - 5.5 m, must be guaranteed.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen. Diese Vorrichtung soll zudem eine möglichst schnelle Vermessung bzw. Prüfung des einzelnen Brennelementkastens ermöglichen.The invention is based on the object of providing a device of the initially described called type to create. This device should also be as fast as possible Allow measurement or testing of the individual fuel assembly.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein oder mehrere Träger für in einer Querebene liegende Meßtaster relativ zum Brennelementkasten und parallel zur ideal-geometrischen Oberfläche des Brennelementkastens schrittweise bewegbar sind, und daß jeder Seite des Brennelementkastens drei Meßtaster zugeordnet sind, deren einer auf die Mitte und deren andere auf knapp neben den Eckradien liegende Punkte gerichtet sind.This object is achieved according to the invention in that one or more Carrier for probes lying in a transverse plane relative to the fuel assembly box and gradually parallel to the ideal geometric surface of the fuel assembly are movable, and that each side of the fuel assembly three Measuring probes are assigned, one on the middle and the other on just short points lying next to the corner radii are directed.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dar gestellt. Es zeigt: Fig. 1 die Vorderansicht (Rückansicht) auf einen zu vermessenden Brennelementkasten mit der einen Abstützung, teilweise im Schnitt, Fig. 2 die Rückansicht (Vorderansicht) auf den Brennelementkasten mit der anderen Abstützung, teilweise im Schnitt und Fig. 3 die Zuordnung der Meßtaster zu einer der Prof kurven des Brennelementkastens.An exemplary embodiment of the invention is shown schematically in the drawing represented. It shows: FIG. 1 the front view (rear view) of one to be measured Fuel assembly box with one support, partially in section, FIG. 2 the rear view (Front view) of the fuel assembly box with the other support, partially in section and Fig. 3 the assignment of the probe to one of the Prof curves of the fuel assembly box.

Auf einer Grundplatte 1 mit hochgenauer, in die Waagrechte eingerichteter Oberfläche sind zwei, der Abstützung des zu vermessenden - mehrere Meter langen - Brennelementkastens 4, d.h. des Hüllkastens für ein Brennelement eines Kernreaktors, dienende Halter 2, 3 mit Abstand angeordnet.On a base plate 1 with highly precise, set up in the horizontal Surface are two, the support of the to be measured - several meters long - fuel assembly box 4, i.e. the cladding box for a fuel assembly of a nuclear reactor, serving holder 2, 3 arranged at a distance.

Jeder Halter 2, 3 weist einen auf der Grundplatte aufliegenden Fuß 5 und ein U-förmiges Kopfteil 6a, 6b auf. Auf der Basis 6a jedes Kopfteils befinden sich zwei starre Auflager 7, 8 und ein bewegliches Auflager 9. Das bewegliche Auflager 9 besteht aus einem waagrechten, auf einer Rolle 10 aufliegenden Arm 11, der zwei Lagerelemente 12, 13 für den Brennelementkasten trägt. Die Aurlager 7, 8 und 9 bilden eine Dreipunkt-Abstützung für den Brennelementkasten, wodurch der Brennelementkasten statisch bestimmt abgestützt ist. An den beiden nach oben gerichteten Schenkeln 6b jedes Kopfteils sind ein fester (14) und ein beweglicher (14a) Anschlagbolzen zur seitlichen Fixierung des (zu vermessenden) Brennelementkastens angebracht. Die unmittelbaren Lagerstellen für den Brennelementkasten liegen in einer zur Oberfläche der Grundplatte 1 parallelen Ebene.Each holder 2, 3 has a foot resting on the base plate 5 and a U-shaped head part 6a, 6b. Located on the base 6a of each headboard two rigid supports 7, 8 and a movable support 9. The movable support 9 consists of a horizontal arm 11 resting on a roller 10, the two Bearing elements 12, 13 for the fuel assembly box. Form the supports 7, 8 and 9 a three-point support for the fuel assembly box, whereby the fuel assembly box is supported statically determined. On the two upward facing legs 6b each head part is a fixed (14) and a movable (14a) stop bolt for lateral fixation of the (to be measured) fuel assembly box attached. The immediate Storage points for the fuel assembly box are located in one to the surface of the base plate 1 parallel plane.

Zum Vermessen der Außenkontur des Brennelementkastens 4 dienen auf elektrischer Grundlage arbeitende Meßtaster 15, die repräsentativen Punkten des Profiles des Kastenquerschnittes zugeordnet sind. Die Meßtaster 15 sind an zwei Trägern 16, 17 befestigt, von denen jeder einen senkrechten Arm 18 und einen waagrechten Arm 19 aufweist. Die Träger 16, 17 sind gegenüber dem Brennelementkasten parallel zur tdeal-goometrlsohen Oberfläche (Seitenfläche) des ttI.1t.kftsteflz verschiebbar geführt. Als Bezugs-Führungsflächen für die Träger 16, 17 dienen die Oberfläche der Grundplatte 1 und die Seitenflächen 20 jeweils eines auf der Grundplatte fest angeordneten FUhrungslineals 21.To measure the outer contour of the fuel assembly box 4 are used electrical basis working probe 15, the representative points of the Profiles of the box cross-section are assigned. The probes 15 are on two Straps 16, 17 attached, each of which has a vertical arm 18 and a horizontal Has arm 19. The carriers 16, 17 are parallel to the fuel assembly box Can be moved to the tdeal-goometrl-like surface (side surface) of the ttI.1t.kftsteflz guided. The surface serves as reference guide surfaces for the supports 16, 17 the base plate 1 and the side surfaces 20 each fixed one on the base plate arranged guide ruler 21.

Die Meßtaster 15, wahlweise elektronisohe Taster oder Meßuhren, werden an den einzelnen Armen 18, 19 mittels einer Lehre 22 auf die vorher festgelegten Punkte des Soll-Profiles eingestellt. Versuche haben ergeben, daß jeweils drei Meßtaster 15a, 15b, 15c pro Seite genügen, wobei der mittlere (15b) der Seiteinitte und die beiden äußeren (15a, 15c) Punktenknapp neben den Enden der Eckradien zugeordnet sind.The measuring buttons 15, optionally electronic buttons or dial gauges, are on the individual arms 18, 19 by means of a gauge 22 on the previously established Points of the target profile set. Tests have shown that three probes 15a, 15b, 15c per side are sufficient, with the middle (15b) of the side center and the two outer (15a, 15c) points assigned just next to the ends of the corner radii are.

Das Verschieben der Träger 16, 17 erfolgt schrittweise von Hand oder durch einen Antrieb, wobei - entsprechend der Länge des Brennelementkastens - eine ausreichende Zahl von Querschnittsebenen - z.B. 18 bei 4 m Länge - abgetastet werden. Die elektronischen Meßtaster bzw. Meßuhren werden zweckmäßig vorher so eingestellt, daß nur die Abweichungen von der ideal-geometrischen Form des Brennelementkastens angezeigt werden. Die Ausschläge der Meßtaster werden entsprechend vergrößert aufgezeichnet und ausgewertet. Das Ergebnis der Vermessung kann aber auch in Form einer Lochkarte festgehalten und automatisch ausgewertet werden.The carrier 16, 17 is moved step by step by hand or by a drive, whereby - according to the length of the fuel assembly - a A sufficient number of cross-sectional planes - e.g. 18 with a length of 4 m - can be scanned. The electronic probes or dial gauges be expedient beforehand adjusted so that only the deviations from the ideal geometric shape of the fuel assembly are displayed. The deflections of the probes are recorded enlarged accordingly and evaluated. The result of the measurement can also be in the form of a punch card recorded and automatically evaluated.
