Neutron fluence measurements applied to reactor materials irradiation

Outgoing from the needs for neutron fluence measurements in the field of reactor material irradiations, a general review of the measuring methods is presented, including the discussion of their specific advantages and drawbacks. The application of the activation detector method is treated in more detail; special points are the choice of certain detector reactions, resp. materials, corrections and evaluation. Post-irradiation processing and measurement of the activated detectors is described. Concluding, selected monitoring problems and their treatment is discussed, like the monitoring of High-Temperature Reactor material irradiations and the demands for monitoring of radiation damage investigations
