ENEXSA | ADVERTORIAL FEATURE
All round talent meeting nuclear challenges Conceptual design, process simulation, and performance monitoring of
nuclear power plants all require a comprehensive and versatile modelling tool.
The complex steam cycle of nuclear power plants includes steam extractions at different pressure levels and moisture separator/reheater, as well as moisture removal stages for processing moderately superheated or wet steam. It creates a highly intertwined topology that requires a robust and fast-converging solver. The influence of moisture on the expansion
process in the steam turbine, as described by Baily, Booth, Cotton and Miller in their famous 1973 technical paper, goes far beyond simple textbook equations and requires the ability to add and manage a variety of correlations for both design and off-design simulations.
EBSILON® Professional may not be well known
yet in the global nuclear industry, but it has been performing an excellent job in the nuclear arena for more than 30 years. EBSILON®
Professional by IQONY Solutions,
Germany, was introduced in 1991 and has become a leading heat balance software used by major utilities, independent power producers, OEMs, engineering companies and R&D institutions world-wide. Since 2008, ENEXSA – a team of experienced process engineers and
Applications in nuclear power plants Over the last decades, EBSILON models have been used in performance monitoring systems, for planning purposes, and as educational tools primarily in Germany but also in the United States, Spain, Sweden, and China. EBSILON’s data
software developers based in Austria – has been cooperating with IQONY Solutions in the development of EBSILON. In a single package, EBSILON today covers all power generation technologies while at the same time providing options to integrate user-defined functionality and state-of-the-art interfaces to link to other software applications. Add-on packages allow for application-specific expansions, such as libraries for gas turbine and gas engine performance data, or detailed radiative heat transfer or thermal-hydraulic modelling. With a dedicated Europe-based development team of seven engineers and both a huge external user base and extensive in-house engineering use at IQONY and ENEXSA, EBSILON continues to improve and modernize to keep up with evolving power generation and software technologies.
reconciliation features lower the uncertainty of the operational measurements by combining statistical analysis with the laws of nature such as mass and energy balances, which effectively supported the permitting of power uprates, as margins to the limits could be reduced.
What comes next? With SMR and new technologies emerging, the scope of modelling is expanding. In addition to the IAPWS-IF 97 and IFC 67 formulations for the properties of water and steam, EBSILON includes further libraries for fluids, such as NASA, NIST RefProp, and other fluid-specific property sets, e.g. for supercritical CO2
or molten salts. It also provides options to
include user-defined fluids in a standardized scheme as a quick work-around solution until state-of-the-art fluid property formulations become available. And, of course, EBSILON can combine any required technology mix into a single comprehensive model.
If you’re having trouble modelling your new concepts with your current tools, let us know. We will be happy to help.
