The joint project was initiated to investigate if and to which degree native or chemical pretreated coal can be metabolized or degraded by microorganisms. The experimental results obtained by university partners of the project indicated that anaerobic rea...

Actual Point of Research: Todays used tanks for storage and transportation of gases are made of metal. They mostly are cylindrical with welded caps and used to be very heavy. Intention: By coating CFRP with thermal spraying, a composite structure with imp...

The following investigations are described: (1) Isolation and cultivation of marine luminescent bacteria, especially strains with higher optimum temperatures, testing of their applicability in toxicity tests, and attempts to standardize the procedure. (2)...

For in situ and on site treatment of PAH contaminated soils biotechnological methods were developed and applied. The selection of suitable areas for field experiments was investigated by sampling and hydrogeological investigations. Soil samples were chara...

This project investigates the fabrication of microwave components by use of high-Tc superconductors. Detailed descriptions are given of the manufacturing and use of active Y-Ba-Cu-O components. The surface resistance of thin films used in high-quality pas...

Heat transfer at pool boiling from three novel finned tubes with different fin geometry to the new refrigerants R134a (CH(sub 2)F.CF(sub 3)), R152a (CH(sub 3).CHF(sub 2)), R227 (CF(sub 3).CHF.CF(sub 3)) and to a nearly equimolar mixture of R134a and R152a...

In this research sub-project four main topics have been treated: (1) Physical fundamentals of high-temperature hydrides: (Mg(sub 2)Ni, Mg(sub 2)Cu, Mg(sub 17)Y(sub 3), MgCo(sub 2), Mg(sub 2)Ca, Mg(sub 17)La(sub 2), TiNi(sub x)Fe(sub y)) The target of thes...

The report describes the creep-rupture tests carried out with a 17Cr-13Ni-2Mo-steel in the frame of the German-Spanish collaboration (KfK-CIEMAT). The material studied is the austenitic steel AISI 316(L) selected as potential first-wall material for NET (...

The investigations were carried out with the aim to quantify the effects of stable iodine taken up in various concentrations with the food on the rates of radioactive iodine-131 eliminated in the milk. The experiments clearly pointed to the fact that vari...

In the event of a severe reactor accident involving core meltdown, sumps containing fission iodine can form in the annulus and in the auxiliary building of a PWR. Iodine revolatilization from these sumps has to be considered. The report contains results o...

The report comprises the operation period of the 10 t/h-prototype plant from June 1989 until January 1991. The test operation of the gasification was successfully completed. The technological qualification and the long-term operability of the technologica...

The study gives a survey on the training methods for the operating personnel of reactors in operation or under construction in the FRG and compares them with the training and testing methods of other countries, in particular the USA. (RW/AK)

The final report of the project 'Evolutionary Diesel Engine 2000' outlines the development of a direct-injection diesel engine for passenger cars. It comprises the following chapters: Comparison and assessment of different fuel injection systems; Design o...

With this 'Sonder-Demo' research program we demonstrated that these 25 kW elektrOmat wind generators with used synchronous generators and grid-steered alternators can be installed at nearly all sites, even with low-wind and strong-wind conditions. After f...

Processes for refined waste water purification combining adsorption, flocculation, and filtration can be optimised with regard to filter service life, filter charge rate and output quality by adding a sedimentation stage upstream the filter to enhance the...

The research project aimed at obtaining verifiable knowledge of structural development during welding, precipitation and embrittlement tendencies, changes of the austenite-ferrite ratio, and corrosion behaviour, for the application of such coatings to che...
