摘要：

Neutron detector response to power reactor mechanical structure vibrations is computed in order to obtain a quantitative reference for noise analysis. For a space-dependent approach in large cores, Cohn's method of reducing time-dependent neutron balance equations to statics equations was considered. In order to produce detector response matrices, depending on many vibrating sources' and frequencies, a dedicated 3-D code was developed. Simulations indicated that response matrices could be used to locate vibrating sources for low local to global noise ratios and to obtain their vibration amplitudes. (C) 2003 Elsevier Ltd.
