VTT's APROS software is renewed to simulate nuclear power plants of the future

VTT Technical Research Centre of Finland has released version 5.08 of APROS (Advanced Process Simulation Software) that is widely used for process modelling and optimization of nuclear power plants in particular but also of other industrial processes. The most difficult process failures can be simulated using this software.

According to the main designer of the APROS software, Dr Kaj Juslin, Chief Research Scientist at VTT, it is developed to suite analysis needs of evolving new types of power plants such as Gen4 nuclear power plants and clean combustion power plants.

APROS version 5.08 brings several new features for the end-users. APROS steam tables have been extended to the supercritical region of interest in the design of new and more efficient power plants. Provisions are made for calculation of typical Gen4 coolants such as helium, sodium, lead and salts. Material properties for hydrogen and hydrocarbons, for example, are available for calculation of reactions and flows in synthetic fuel production processes.

APROS provides for elementary model building blocks enabling the user to graphically specify more extensive process component models in detail. Elementary blocks for the calculation of heat accumulation and diffusion in structures cover both plate, cylindrical, and spherical geometries. Model specifications can be written to ASCII-files using the versatile model specification language of APROS and easily transported to new software versions, computer hardware or operation systems. The specification language enables interconnection of APROS to other design tools and especially to new semantic design databases of both processes and control systems.

APROS simulation software is used in 20 countries. In Finland, it has been exploited in independent analysis calculations of the EPR plant under construction in Olkiluoto and in designing new digital automation systems for the Loviisa VVER plants. Other full-scope ARPOS-based simulators have been developed to replicate nuclear power plants of Russian, Swedish and Chinese design. As well as a design tool for prominent contractors and engineering agencies, APROS is used in training on how the processes operate.

APROS is the result of two decades of continuous and dedicated developments by VTT experts in co-operation with the Finnish energy company Fortum. The quality of each new version is thoroughly verified and validated. Along the way, end users have given valuable feedback and new goals to the developers. Now, for instance, the need for calculations that are hundreds of times faster than real-time in predicting simulators has been made clear to developers.

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
