Raziskave

Raziskave Odseka za reaktorsko tehniko se osredotočajo na računalniško modeliranje fizikalnih procesov, ki so pomembni za obratovanje in varnost jedrskih elektrarn.

Rezultati eksperimentalnega dela, ki so potrebni za potrditev in veljavnost naših simulacij, so pridobljeni z mednarodnim sodelovanjem in s projekti, ki imajo dostop do mednarodne infrastrukture.
