This report presents the development and the use of a Lasersystem that when used in conjunction with the $\beta$- and $\gamma$- spectrometry, is suitable not only for determination of fission product-concentrations and their local distribution inside the coated particles but also for determination of release of solid fission products out of particles with defined defects in the coating. The investigation of the release behaviour of particles with Laser-induced defects gives the first direct proof for the reduced Cs-release of damaged particles with kernel additions which are capable to "getter" fission products by comparison with those without kernel additions. The use of the Laser to determine the distribution of fission products inside the particles partly completes the methodically caused information gaps in the fission product-transport data established with other detection techniques. |
