Zamenjava premogovnih enot Termoelektrarne Šoštanj s tehnologijo malih modularnih reaktorjev

Lončarič, Simon (author), Sekavčnik, Mihael (mentor)

V diplomski nalogi je obravnavana možnost postopne nadomestitve premogovnih enot Termoelektrarne Šoštanj z malimi modularnimi reaktorji (SMR). Analiza zajema primerjavo različnih tehnologij reaktorjev ter oceno njihove primernosti za integracijo v obstoječo infrastrukturo. Poseben poudarek je namenjen reaktorju BWRX-300, ki se je izkazal kot najprimernejša izbira zaradi tehnološke zrelosti, geopolitične sprejemljivosti in skladnosti s potrebami slovenskega elektroenergetskega sistema. Predstavljeni so tudi izzivi, povezani s prilagodljivostjo obratovanja, možnostjo uporabe hranilnikov energije ter ohranitvijo obstoječih infrastrukturnih zmogljivosti.

• Title: Replacement of coal units at the Šoštanj power plant with Small Modular Reactors

Abstract

This thesis addresses the possibility of gradually replacing the coal-fired units of the Šoštanj Thermal Power Plant with small modular reactors (SMRs). The analysis includes a comparison of various reactor technologies and an assessment of their suitability for integration into the existing infrastructure. Special emphasis is placed on the BWRX-300 reactor, which has proven to be the most suitable option due to its technological maturity, geopolitical acceptability, and alignment with the needs of the Slovenian electricity system. The thesis also discusses challenges related to operational flexibility, the potential use of energy storage, and the preservation of existing infrastructure capacities.
