Evaluation of radiation impact on NPP personnel in GDR

The functioning of GDR state system for NPP personnel safety control is described. Taking two NPPs of 1830 MW(e) as an example, the activities within the scope of internal/external irradiation control programmes are demonstrated. The presented measurement results show the NPP personnel dose commitment to be within the accepted standards or much lower than the permissible limits. The collective dose commitments from the external irradiation are at the lowest part of world practice range. The major contribution into the dose commitment is obtained during fuel reloading, inspections and equipment maintenance operations. The contribution from the internal irradiation is negligible
