Abstract:
In the frame work of up-dating non-destructive examination techniques,linked up with industrial demands ECN has started the project VENDEOS,
verification of non-destructive versus destructive testing techniques of fuel
pins. The objectives of this verification are easy to state but may not be
easily achieved. In this case also comparative examinations of both
techniques will be performed. To this end a niobia doped type of fuel has
been chosen. The following program me is planned; Non-Destructive: -
Irradiation programme at the HFR; - Neutrography at 0 and 90 degrees after
irradiation; - Gamma spectrometry; Pulse Height Analyzing (PHA); Gross gamma
scan (area 350 through 850 keV); Multi Nuclide Scan over the total fuel
stack; Computer Tomography at 4 axial locations; Fission gas release
measurement (PHA) at the plenum region; - Visual inspection with a color
camera system; - Profilometry measurements; - Eddy-Current Testing.
Destructive measurements: - Puncturing of the fuel pin for: Fuel pin
pressure; Fission Gas Release; Determination of krypton and xenon by
mass-spectrometry; Void volume determination; - Fabrication of 3 or 4 samples
for further examinations. The positions for cutting will correspond with the
tomography axial positions; - Macro photographs; - Alpha and beta auto
radiography; - EPMA, Electron Probe Micro Analyses; - Micro gamma scanning,
two cross lines with small step size; - Pore size distribution. In this
report the non-destructive examinations of profilometry and eddy current
testing are presented. In the same programme the following reports have been
written: ECN-1--95-019, Gamma spectrometry of VENDEOS 263-05. ECN-1--95-044,
Gamma emission computer tomography of VENDEOS 263-05. 25 figs., 7 tabs., 2
