Abstract:
The experiment series R276 (MANIA) is part of a materials' irradiationtesting program, investigating different types of stainless steel. The
experiments are, or have been irradiated in the HFR Petten. This report
presents the final metrology results obtained from activation monitors in the
specimen holder MANIA-10, coded as R276-10, containing austenitic stainless
steel 316HIP-BONDED. The monitor sets are used to calculate the thermal and
fast neutron fluences, displacements per atom and the generated helium
content. The irradiation circumstances for this experiment, carried out in a
TRIMURTI insert placed into channel 03 of a TRIO type capsule in HFR position
G3, represent the conditions at the first wall of NET (Next European Torus).
The aim of this irradiation for specimen holder R276-10 was to reach a damage
level of nearly 5.0 dpa at a temperature of 275C. The main results of the
thermal and fast neutron fluence measurements, indicate that the maximum
obtained damage levels are slightly more than 4.0 dpa. 17 refs.
