OSTI ID:4843869
For the detection of bursts of fuel elements, the activity is measured of the solid decay products of gaseous fission products, which may be conveyed by a portion of the reactor coolant coming at a given instant from a selected reactor channel. For this purpose the coolant sample is led beforehand through a chamber in which a sufficient portion of the said decay products may be formed and is then led into a precipitation chamber. A part of the wall of the latter chamber is formed by the surface of a collecting drum constituting the negative electrode. A repulsion electrode is placed in front of the surface of the drum. The solid decay products collected on this drum during a precipitation period are then transposed by a rotation of the drum and brought in front of a scintillation counter to measure their activity.
