[en] Nuclear waste management in West Germany still depends on the loyalty of the French partners to present agreements. If the French should break the contract, German nuclear power plants would have to be shut down one by one according to their refuelling schedules. If power plant operators were prevented from setting up compact storage facilities, as the decision of the Darmstadt administrative court seems to indicate, this situation would be quite likely to occur.

[en] The purpose of the invention is a selective filter material absorbing the element iodine. Starch is used as the material absorbing the iodine. The element iodine is incorporated in the spiral hollow spaces of the starch. The mechanism of incorporating is due to Van der Waal forces. The filter effect is not affected by salt loading or by extreme pH values of the water to be cleaned. (orig.)

[en] A process for treating waste water containing hydrazine from nuclear power stations is proposed, characterized by the fact that the water is taken continuously through a water decomposition cell. If the water does not have sufficient conductivity itself, a substance raising the electrical conductivity is added to the water to be treated. The electrolysis is situated in the waste water tank.

[en] The waste air is led across a catalyst on which organic iodine compounds are decomposed. The elemental iodine is retained in adsorption filters. (orig./HP)

[en] An analytical program for irradiation planning is presented for the 60-beam π-applicator (Piotron). Using this program, the three-dimensional dose distribution can be calculated for an arbitrary orientation of the patient and arbitrary applicator parameters. To study the influence of inhomogenieties of the human body, the stopping power for π^--mesons has been measured for relevant materials. As a result, the stopping power of heavy particles can be described with a high precision by the Bethe-Bloch-equation using an appropriate average of the ionisation potentials. Thus also the range variations due to inhomogenieties can be taken into account by an analytical program. To verify the calculated dose distributions, an experimental method has been developed to measure the three-dimensional π^--dose distributions simultaneously, using CaF₂:Tm thermoluminescence dosemeters. From the analysis of the glow curve the total dose can be determined as well as the mean LET-value, so that the distribution of the biological efficiency can be predicted. A special treatment of the TL-materials opens new possibilities for the application in ''in vivo'' dosimetry, for the dosimetry of other heavy charged particles and for neutrondosimetry. (orig./HP)

[en] Automatic translation: Summary: The overall objective of the present assessment of the IWR degassing technologies for the HTR is, touchpoints in the outer fuel cycle, especially for reprocessing and. Waste treatment, between HTR and LWR line and to determine which of the established LWR technologies for the HTR fuel cycle can be taken over in full or in modified form. As a reference for the LWR restoration, a 1,400 jato system based /1/. The characterization of this Reprocessing plant takes place up to a the process qualitative descriptive detail. The single ones Material flows of the various process steps are with regard to the amount of flow, acid, uranium and plutonium concentration as well as the specification of the specific activity.

[en] The value of the critical revaluation of reactor lines will however be determined by the Munster for Research. Despite the amount of facts which evoke doubts whether the further financing of both projects is still reasonable, would be considered as ''admitting that Germanys economy and sciences are incapable to deal with complex modern technologies'' of Germany gave up the breeder and high-temperature reactor projects. Fears exist that ''thus will have considerable effects on the overall economic situation''. So they want to carry on. (orig./GL)

[en] In 1982 and 1983, the Federal German Minister for Research and Technology, Mr. Riesenhuber, put into effect what his predecessor, member of the SPD, Mr. von Buelow, had been aiming at: The power industry had to contribute a larger share to the construction of the SNR-300 near Kalkar. Up to then, their commitment amounted to only DM 200 millions, although the utilities clearly will draw most benefit from the new technology. The financing share to be paid by the electricity supply companies was then fixed to DM 1.4 thousand millions. The Federal Government is in with DM 4.2 thousand millions, and adding the contribution by Belgium and the Netherlands, public funds are contributing DM 5.2 thousand millions. The remaining investments come from the nuclear industry (DM 340 millions) and from banking establishments (loans amounting to DM 100 millions). In reality, however, the utilities share only is about DM 400 millions, as they in advance obtained permission to pass on one thousand millions of expenses to the customers, via the electricity rates. Should the Kalkar SNR-300 now be left uncompleted, claims for damages would pile up to a total of about one thousand millions (of which 400 millions will be claimed by the power industry, 340 millions by the nuclear industry, and 100 millions by the banks).

[en] Andreas von Buelow, Federal Minister for Research and Technology, wants to avoid becoming a target for the opposition as Hans Apel, Minister of Defense, has. For this reason, an independent expert is to find out why the development of new nuclear reactors has become so expensive. According to the latest estimation, there is a financing gap of DM 1.500 million. A breeder capacity of 10,000 MW (ten breeders) would save only about DM 200 million for imported natural uranium. On the other hand, the additional cost of the ten breeders amounts to DM 30,000 million. It seems that public utilities have found this out even before von Buelow has asked them for cash. (orig.)
