Abstract
To qualify the calculation methodology, measurements of neutron flux responses of a VVER-440/230 reactor pressure vessel have been carried out.
The activity of shavings sampled out from the inner pressure vessel wall of Unit 1 of Kozloduy NPP after the 14th cycle has been measured. Calculation of the expected activity at the shaving positions has been carried out, taking into account the local power distribution. Comparison of calculated and measured activity values has indicated that the computed value for the fast neutron fluence is underestimated by up to 20%.
