Method of Cladding Rupture Localization by Tracer Gases - Experience Acquired by CEA (English Translation of Methode de localisation des ruptures de gaine par gaz traceurs - experience acquise au cea)
- Commissariat a l'Energie Atomique (CEA), Grenoble (France)
One method of cladding rupture localization (CRL) consists of introducing a certain volume of· "tracer" gas (or "label") into all pins of one assembly. The selected gases which must differ from fission gases are kryptons and xenons of specific isotope composition with light-isotope enrichment (Kr-78, Xe-124, Xe-126, Xe-128). In the case of cladding rupture, this tracer gas is transferred into the blanket argon. An activated carbon trapping device and mass spectrometry then allow a measurement of the isotope ratio (Kr-82/Kr-78, Xe-129/Xe-124 or Xe-129/Xe-126) identifying the tracer. Topics discussed include: Labeled Assembly Fabrication Experience; Labeling Experience in RAPSODIE; and Labeling Experiment in PHENIX.
