Samenvatting:
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 in Petten, Netherlands.
This report presents the final metrology results obtained from activation
monitors in the specimen holder MANIA-11, coded as R276-11, 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
R276-11 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
