Device for measuring the diameter of a rod for a nuclear reactor fuel element

Creators

Description

The device is used for the underwater determination of the diameter of a control rod of a PWR over its whole length. The guide is pivoted on the support on two pivots, which are at right angles to one another and to the longitudinal direction of the guide channel. Fitting bodies elastically sprung in the radial direction are provided for the rod on the wall of the guide channel. The second measuring cutter is supported elastically sprung in the direction of the measuring diameter. (orig./HP)

Abstract (German)

Die Vorrichtung dient zur Unterwasser-Durchmesserbestimmung eines Regel- oder Steuersatzes eines DWR ueber die gesamte Laenge. Der Fuehrungskoerper ist am Haltekoerper um zwei Schwenkachsen schwenkbar gehaltert, die zueinander und zur Laengsrichtung des Fuehrungskanals rechtwinklig sind. An der Wand des Fuehrungskanals sind elastisch in Radialrichtung federnde Anlagekoerper fuer den Stab vorgesehen. Die zweite Messschneide ist in Richtung des Messdurchmessers elastisch federnd gehaltert. (orig./HP)
