Goal of this dissertation is to establish increasing of radioactive discharges with reference to projected construction of next nuclear power units. This dissertation describes radionicludes composition in gaseous also liquid discharges and resulting impact to individual from critical group of the public. Dissertation includes annual summaries of discharges, released into environment during Temelín NPP operation. Procedure of the analysis: 1) calculation of average annual activity of most considerable radionuclides 2) determination of environment influence to radionuclides distribution 3) calculation of supposed committed effective dose 4) calculated supposed committed effective dose comparison with actual authorized limit, with double authorized limit and with dose constraint for effective dose for individual from critical group of the public, caused by discharges of radioactive substances Main conclusion of this dissertation is suggestion of to increase authorized limits for individual from critical group of the public: for gaseous discharges: 50 % above current value {--} it means 60 {$\mu$}Sv per calendar year for liquid discharges: 100 % above current value {--} it means 6 {$\mu$}Sv per calendar year This values are quite acceptable in comparison with dose constraints defined by Regulation No. 307/2002 of Coll., § 56, section 3 {--} {\clqq}average effective dose of 250 {$\mu$}Sv per calendar year for the appropriate critical group of the public, from which 200 {$\mu$}Sv shall be for discharges into the atmosphere and 50 {$\mu$}Sv for discharges into watercourses``. It is possible to utilize this dissertation in process of new nuclear power units projection, next this dissertation demonstrates radiation protection optimisation in area of radioactive discharges according to valid legislation.
