Abstract

Cilj ovog rada je koncipiranje i konstruiranje prototipa uređaja za instaliranje Forerunner manipulatora tvrtke INETEC, na vertikalnu cijevnu stjenku parogeneratora. Na samom početku, ukratko je opisana pojava nuklearne reakcije te uvjeti za njezino iskorištavanje u nuklearnim elektranama. Nadalje su opisani podsustavi nuklearne elektrane te ključni dijelovi neophodni za održavanje nuklearne reakcije. U nastavku je opisan način rada i konstrukcija parogeneratora kao okoline sustava u kojem će se nalaziti uređaj koji je predmet ovog diplomskog rada. Analizom patenata i postojećih rješenja na tržištu dobiven je uvid u nekadašnje i trenutno stanje tehnike, na području instalacije objekata u parogenerator sa svrhom nerazornog ispitivanja cijevi. Razvoj uređaja započeo je izradom tehničkog upitnika i utvrđivanjem definicije cilja razvoja. Nakon toga utvrđene su tehničke specifikacije uređaja te je kreirana funkcijska dekompozicija uređaja. Rješenja pojedinih funkcija, uz pomoć morfološke matrice, poslužila su stvaranju koncepta. Uređaj je podijeljen na 3 podsustava, a za svaki su kreirani zasebni koncepti. Nakon evaluacije, odabrani koncepti su uklopljeni u konačno rješenje koje je poslužilo kao osnova za konstrukcijsku razradu. Proračunom su provjerene kritične točke uređaja, poglavito kritična mjesta nosive konstrukcije, te su odabrane standardne komponente. 3D računalni model i tehnička dokumentacija izrađeni su pomoću programskog paketa Autodesk Inventor 2016.

Abstract (english)

The main goal of this thesis is the product development of an installation device for INETEC's Forerunner mobile robot on a steam generator tube sheet. First, the nuclear reaction and its use in nuclear power plants are briefly described. To continue, nuclear plant key systems vital for maintaining the nuclear reaction inside the plant are described. Following that up, steam generator design and work schematics are explained as an operating environment for the device being developed in this thesis. An overview of Forerunner specifications is given. Market and patent research give insights into past and current state of the art in the field of installation devices in steam generators. The development begins by establishing product specifications and development goals. A functional decomposition is made by listing all the product sub functions and connecting them with flows of energy, material and information. Technical solutions for each sub function are listed in a morphology and combined into individual concepts. Several concepts were generated for each of the device’s sub-systems. By evaluating the concepts, the most appropriate were chosen to form the final solution. This final solution served as a basis for further development. Further development included stress calculations in critical points of the support structure and selection of standard components. 3D CAD model and following technical drawings and documentation were made with the help of Autodesk Inventor 2016 CAD program.
