Purpose: justification, development and trial operation of elements of unified system for the account and registration of external and internal doses of the personnel of A category in NPPs. Methods: dosimetric (instrumental and calculational), statistical. Results: The analysis of influence of initial parameters uncertainty on internal dose assessment uncertainty for personnel of A category in NPPs. It is determined that the main source of uncertainty during internal dose assessment is an unknown date of intake. For the personnel which take part in dose-intensive works, this uncertainty can be essentially reduced due to the operational control. Calculation of derived investigation levels for measurements on whole body counters is executed. Trial operation of a method for determination of a gamma-radiation field anisotropy on NPPs workplaces is carried out. It is determined thatat works in reactor compartment during planned maintenance anisotropy reaches high values and for an effective dose assessment it is necessary to use alternative methods (combined measurements by several dosimeters).
