ANNOTATION:
The paper presents computational and experimental studies focused on the radiation characteristics of the reactor vessel and reactor internals performed to estimate the volume and the characteristics of activated intermediate- and high-level waste expected to be generated from the decommissioning of unit No. 3 at the Novovoronezh NPP. Two software products, namely, MCU-6 and Serpent were used in the calculations by the Monte Carlo method. To verify the calculation results these were compared with data on metal samples of the reactor internals and reactor vessel obtained from their laboratory studies.
Keywords: induced activity, WWER-440, Monte Carlo method, spectrometry, verifi ation, decommissioning, radioactive waste.
