Digital Modeling Automated System for Liquid NPP Radioactive Media Treatment
Abstract
The development and implementation of treatment technologies for the liquid radioactive waste (LRW) and liquid radioactive media (LRC) of nuclear power plants are among the most complex tasks of the modern nuclear power industry. The paper presents scientific research automated system (SRAS) designed for digital modeling, analysis and optimization of production and technological chains (PTC) for the management of LRW and an ontologically oriented approach that provides formalization of technological flows, redistributions and their interrelations in the form of a directed graph of transformations. A modular architecture has been developed, including data management tools, a technology knowledge base, a modeling module, and analysis and decision support tools. The system implements mathematical models of technological processes used in the existing LRW reprocessing complexes of NPPs with VVER reactors. The key mechanism is a digital experiment that makes it possible to study the behavior of PTCs when varying the parameters of input streams and the structure of the chain. The system passed acceptance tests and trial operation in 2025 and is registered as a computer program.
