Today, most software applications, also in the nuclear field, come with a graphical user interface. Recently, the Symbolic Nuclear Analysis Package (SNAP) was designed to simplify the process of performing safety analysis. The purpose of the present study was to develop an SNAP animation model for RELAP5 calculations of a nuclear installation. The facility selected was the Rig of Safety Assessm...

A web-based nuclear reactor simulator has been developed using the best-estimate nuclear system analysis code RELAP5 as its engine, and abVIEW for graphical user interface and web-casting. Simulator retains the accuracy of the best-estimate code. Results are displayed in user riendly graphical format. Color-coded nominal values are displayed along with the current status of different variables ...

Containment building is the final barrier for radioactive releases from a nuclear power plant (NPP). Preserving its integrity will minimize these even in case of severe accident with core degradation and melt discharge containment accompanied pressure temperature increase. Installation venting system ability to filter fission products preferred way deal issue present future NPPs, especially aft...

The system code ATHLET (Analysis of THermal-hydraulics Leaks and Transients) is being developed by the Gesellschaft für Anlagen-und Reaktorsicherheit (GRS) mbH in Garching, Germany. In paper, an overview activities performed at Faculty Electrical Engineering Computing (FER), University Zagreb, application transient analyses for NPP Krško (NEK) presented. Newly, NEK input deck released version (...

The present paper describes the experimental campaign executed at ENEA Brasimone Research Centre aiming supporting development of a PbLi/water heat exchanger suitable for lithium–lead loops dual coolant lithium lead and water cooled breeding blankets EU DEMO fusion reactor. experiments were performed in test section named HERO, installed inside main vessel lead–bismuth eutectic-cooled pool-type...
