Testing System Development for Full-Scale Simulators of Nuclear Power Plant Unit

Abstract

The full-scale simulator (FSS) of nuclear power plant (NPP) unit is designed for operating personnel professional joint training of the power unit’s main control room using its real full-scale model. Testing of all FSS systems has an important place in the software part of the development of FSS. Currently, the development of software testing for FSS systems is required. The article provides an overview ozf modern testing systems. In addition, the article presents the algorithms for the operation of tests designed by using Pytest – the framework for writing software tests. The paper presents the following tests: overpower test and check for the presence of chugging; test of the correctness of the decay heat model in terms of amplitude in the event of scram and stable attenuation of decay heat after scram.
