Abstract
A new method of determining the fluence with an integrating diamond sensor is developed. The method is based on the results of many experiments on combined irradiation in VVER-1000 of diamond sensors and control samples for which activity data on the fast-neutron fluence were obtained from the 54Mn by a computational-experimental method. The expansion of the crystal lattice of irradiated diamond, which is measured with a comparatively high accuracy, is used as the measured property. The new method is free of many of the drawbacks of the activation method, and its relative accuracy is higher than the accuracy of the computational-experimental method, especially for a long holding time in the reactor.
