Description The neutron fluence load in structural components of reactor systems is crucial for the issues of reactor dosimetry. The neutron spectrum in construction parts of light water reactor systems is modified by water and iron, whereas the spectrum in advanch (MSR/FHR) reactor systems is shifted by fluoride salts and graphite. The majority of commercial nuclear power plants are light water reactors, where the neutron spectra were examined many times. In case of progressive technologies, as MSR/FHR, neutron spectra are measured only rarely. Therefore, a series of experiments with fast two parametric spectrometric system were performed in LR-0 reactor in order to analyze the effect of graphite and fluorides on neutron spectrum.
