Behavior of Personnel in Radiation Controlled Area /RCA/ in the Temelín Nuclear Power Plant.
SKOKOVÁ, Libuše
My bachelor´s work aims at measures and conventions of radiation protection of persons working in Temelín nuclear power plant radiation controlled area, mainly at using of personal work protective aids. The theoretical part gives description of measures and conventions for work in radiation controlled area and for usage of basic also special work protective aids, next of procedure for enter into/exit out from radiation controlled area, and description of barriers with measuring devices, where is carried out check of persons also clothing's surface contamination. Contains also description of personal doses optimalization system and of tools, used for implementation into practice. Detailed description of rules for usage of work protective aids, according to specific work conditions and radiation conditions, is included in this bachelor´s work. The main research part of this work are summaries of records about persons crossings of persons radiation controlled area borders, and about events of catching persons in measuring devices due to contamination. This summaries are processed into tables and graphs form and arranged so, that relationships between protective aids usage and contamination of workers are obvious. The aim of my work was to establish, whether presently applied rules of radiation protection are followed consistently and if there is a necessity for changes and improvement. For this finding were used all information about controlled area traffic, accessible legislation, statistical data from electronical personal dosimetry system and from electronical nearmiss, events and incidents database. The key findings are data and records about cases, when was necessary to dispose contamination of body surface by medical intervention. and about cases of body internal contamination. Medical interventions were necessary only rare, in year 2016 two times, during previous five years not once. There was not one case of body internal contamination throughout the whole time of Temelín nuclear power plant radiation controlled area operation. After evaluation of all the data, there is obvious, that measures and conventions of radiation protection, applied in Temelín nuclear power plant, are sufficient a there is no necessity of changes.
