摘要

The irradiation experiment R277-01/02 is part of the fusion materials test program to evaluate the mechanical properties of ferritic/martensitic steel. Experiment R277-01/02 contained three different types of FM steel, MANET-II, US-I and F82H-1. The experiment has been irradiated on the HFR Petten, in core position E7 at 300 C up to about 1,5 dpa. The two specimen holders have been irradiated under different circumstances, to investigate the influence of helium on the mechanical properties of the steel. Specimen holder R277-01 contained a B(sub 4)C shield to reduce the thermal fluence rate and consequently the He production. This report presents the final neutron metrology results obtained from the activation monitors in the specimen holders, coded as 01 and 02. Data about the helium production as well as the number of displacements per atom are also included. (orig.). (Atomindex citation 28:006822)
