Measuring device of the flow of the dose in a tower containing radioactive waste materials.

摘要

Front of transport on a site of a flask in which has been placed a container filled with radioactive waste, it is introduced through a hole formed in the flask a door - probe (32) connected by electrical connectors (76, 80) to an external measuring device (36). The door - probe (32) is equipped with a handle (68) making it possible, by means of a mechanism (66, 56, 54, 50), the swinging of a door (42) on which is fixed a probe (34) between a retracted position of introduction and a measurement position in which the probe can be oriented to 90degré with respect to the axis of the door - probe. After the latter has been coupled by a nut (40) on a door - container in which is housed the container containing the waste, a precise and reproducible measurement of the dose rate inside the flask can thus be carried out.
