Essay

The thesis is devoted to the scientific and technical solution of the problem of the pressure vessel radiation exposure determination for VVER-440 operating power Unit. It is shown that the optimal solution of this problem is to use a technique that involves numerical neutron transport calculations within reactor near-vessel space by the transport code based on the Monte-Carlo method, and ex-vessel dosimetry measurements by the neutron-activation method. The complex analysis of the results of determination of neutron flux functionals that characterize the irradiation conditions of VVER-440 re-actor pressure vessel of units № 1 and № 2 Rivne NPP is performed.
