The immediate aim of the research was to study the transient thermal strain behaviour of four AGR type nuclear reactor concretes during first time heating in an unsealed condition to 600 deg. C. The work being also relevant to applications of fire exposed concrete structures. The programme was, however, expanded to serve a second more theoretical p...

The thermohydraulic response on the primary and secondary during transients with and without a break were investigated in the PKL Integral test facility. The results show that: isolating one, two or three of four SGs does not lead to stalling of existing steady state natural circulation in the isolated SGs; the growth of an upper plenum steam bubbl...

The Work Process Program ''PROMO'' has been expanded by the ''Non-steady state supercharging'' project for application to supercharged engines. New program modules were developed for the compressor and the single channel turbine. Due to the modularity of the selected formulation, the non-steady state flow in the system of pipes before the compresso...
The objective of this project performed jointly with the Gesellschaft fuer Reaktorsicherheit, an promoted by the Federal Ministry of Research and Technology, consisted in developing and 'analysis simulator' by which quick and comprehensive analyses of complex reactor accident trees (including multiple incidents) could be carried out. The priority o...
In the FVV project 'Total process analysis', a complete vehicle is simulated by a computer program. The computer component associated with this, which describes the steady state and non-steady state behaviour of the engine was produced here as a special FVV research contract ''thermodynamic car Diesel engine''. To save computer time, the pre-chambe...
