Innovative small and medium sized nuclear power reactors

Ovaj rad obrađuje temu novog pristupa nuklearnoj energiji. Radi se o malim i srednjim nuklearnim reaktorima. Na početku rada se govori o ključnim pojmovima za svaki nuklearni reaktor. Obrađen je općeniti pojam nuklearne elektrane, fisije, nuklearnog reaktora, te dva osnovna modela nuklearnih postrojenja BWR i PWR. Nadalje, obrađuje se općeniti pojam SMR-a te smisao, prednosti i mane tog koncepta. Rad također opisuje i 6 vrsta SMR-a i njihove ključne karakteristike. SMR-ovi koji su opisani u ovom radu su: PHWR-220, CNP-300, VBER-300, NuScale, mPower, UK SMR. Za svaki pojedini reaktor su opisane ključne karakteristike koje ih čine ili će ih činiti veoma bitnim faktorima energetike budućnosti.This paper deals with the topic of a new approach to nuclear energy. Small and medium nuclear reactors. At the beginning of the paper, the key concepts for each nuclear reactor are discussed. The general concept of nuclear power plant, fission, nuclear reactor, and two basic models of nuclear plants BWR and PWR have been elaborated. The general concept of SMR is also addressed, as well as the meaning, advantages and disadvantages of this concept. The paper also describes 6 types of SMR-s and their key features. The SMR-s described in this paper are: PHWR-220, CNP-300, VBER-300, NuScale, mPower, UK SMR. For each individual reactor, the key features that make or will make them a very important energy factor of the future are described
