Effects of Novovoronezh NPP-2 industrial development on the assessment of the external radiation dose to personnel
摘要
The article examines the effects of the Novovoronezh NPP‑2 industrial development on the external radiation dose to personnel calculated using the ROUZ software for design basis accidents. The ROUZ assessment of the dose is compared with the results of mesoscale models used for calculating radiation safety of personnel at nuclear power plants. We have established that increasing atmospheric stability makes ROUZ estimates of radioactive surface contamination for the ground and buildings at an industrial site and personnel exposure doses from clouds and ground surface more conservative than those using mesoscale models, regardless of the propagation direction and emission height.
