Energy and directional distribution of neutrons at the Beloyarsk NPP workplaces is a subject of this study. Measurements of H*(10) rate and neutron energy distribution were taken at 8 workplaces, which can bedivided into three categories: work with spent or fresh nuclear fuel, work with radionuclide neutronsources, work at the rooms adjusted to reactors. The Hp(10) measurements were performed only at 6 outof 8 locations, due to the fact that long term placing of an effective neutron moderator in fresh nuclearfuel storage facility is forbidden. As a result of the research energy and direction distribution of theneutron fields at 8 locations of the Beloyarsk NPP workplaces was obtained. To estimate the accuracy ofthe H*(10) rate and Hp (10) measurements the reference values of dose equivalents were calculatedusing energy and directional distribution. To take into account the difference between the referencevalues and the measured results site-specific correction factors were calculated.
