N2 - We calculate the sink strength of dislocations and toroidal absorbers using Object Kinetic Monte Carlo
and compare with the theoretical expressions. We get good agreement for dislocations and loop-shaped
absorbers of 3D migrating defects, provided that the volume fraction is low, and fair agreements for dislocations
with 1D migrating defects. The master curve for the 3D to 1D transition is well reproduced with
loop-shaped absorbers and fairly well with dislocations. We conclude that, on the one hand, the master
curve is correct for a wide range of sinks and that, on the other, OKMC techniques inherently take correctly
into account the strengths of sinks of any shape, provided that an effective way of appropriately
inserting the sinks to be studied can be found
