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