Measure of 11B, 10B and 7L concentrations in control rods using the nuclear microprobe technique

  • 1. Laboratoire d'Etudes des Materiaux Absorbants, CEA Saclay, Gif-sur-Yvette (France)

Description

The nuclear microprobe technique has been used to measure 10B and 7Li profiles after thermal neutron irradiation of a boron carbide absorber. The measured 10B distribution along the pellet radius has been used to calculate the spatial 7Li distribution with the hypothesis of no lithium migration. This result shows a discrepancy with the 7Li measured distribution, indicating that up to 40% of the lithium may migrate out of the B4C pellet. (author)
