Abstract

Osnovna ideja ovog rada bila je dati uvid u izuzetno bitno područje kontrolnih ventila kao tipa
opreme koji služi ne samo za kontrolu procesa, već i za postizanje optimalnih performansi
nuklearnih elektrana. No, ono što je pri tome najbitnije, to je ispravan odabir strategije
održavanja ovih ventila, kao garancije da će funkciju za koju su namijenjeni obavljati sigurno
i pouzdano.
U radu je dan i pregled suvremenih trendova u području održavanja tehničkih sustava.
Osim toga, namjera je bila i dati kratak prikaz funkcioniranja nuklearnih elektrana te ukazati
na njihov siguran i pouzdan rad, ekološku prihvatljivost te neminovnost. Kao primjer dan je
detaljniji prikaz strategije poslovanja i održavanja Nuklearne Elektrane Krško (NEK).
I na kraju, dat je i pregled razvoja i implementacije AOV programa, detaljne informacije u
svezi utjecaja AOV-a na funkcioniranje NE te konkretne dobiti nakon optimizacije njihovih
performansi, u svrhu čega je predložen i način unapređenja održavanja ovih ventila.

Abstract (english)

The basic idea of this paper is to provide insight into the very important field of control valves
as a type of equipment that is used not only for process control, but also for achieving optimal
performances of nuclear power plants. What is most important is the correct selection of
maintenance strategy for these valves, as a guarantee that the function for which they are
designed will be performed safely and reliably.
Also, this paper gives an overview of contemporary trends in the field of technical systems
maintenance.
Besides, the intention was also to give a presentation of the functioning of nuclear power
plants and point to their safe and reliable operation, environmental acceptability and
inevitability. As an example, a more detailed strategy for operation and maintenance of
Nuclear Power Plant Krško (NEK) is given.
At the end, the review of the development and implementation of AOV program is given, as
well as detailed information regarding the impact of AOV operation on NPP performances,
including all related benefits, for which purpose the maintenance improvement of these valves
is recommended.
