Ion microprobe analyses of ancient human bone

Jankuhn, S.; Butz, T.; Flagmeyer, R.-H.; Reinert, T.; Vogt, J.; Barckhausen, B.; Hammerl, J.; Protsch Von Zieten, R.; Grambole, D.; Herrmann, F.; Bethge, K.

At the Rossendorf nuclear microprobe facility, a beam of protons with MeV energy was used to analyse ancient human bones of the Merowingian period (6-8th
century AD), Emitted X-rays were detected to determine the elemental composition of the bones and to estimate the influence of the burial environment on the
elemental content of the skeletons, In cross sections of human femora, a different behaviour of the radial distributions of the main and trace elements like P, Ca, Mn,
Fe, Zn, Br, and Sr was observed using lateral-resolved mu PIXE. This result indicates post mortem mineral exchange processes and diagenetic alteration during
burial of bone tissue in soil.

Finite element-based vibration analyses of WWER-440 type reactors

Altstadt, E.; Weiss, F.-P.

To support the early detection of mechanical component faults at WWER-440 reactors a finite-element-model describing the mechanical vibrations of the whole primary circuit was established. A special element was developed to describe the fluid-structure interaction in the downcomer. It is based on an approximated analytical 2D-solution of the coupled system of 3D fluid equations and the structural equations of motions.
The vibration modes up to 30 Hz were calculated. It is shown that the fluid-structure interaction strongly influences those modes with a relative displacement between reactor pressure vessel and core barrel.
Moreover, by means of the model the shift of eigenfrequencies due to the degradation or to the failure of internal clamping and spring elements was investigated. Comparing the frequency spectra of the normal and the faulty structure, one could prove that a recognition of such degradations and failures even inside the reactor pressure vessel is possible by pure excore vibration measurements. The results hint at the
opportunity to establish a monitoring procedure that is capable of distinguishing between guide lug and spring pipe failures, because these two types of failures are mapped in different and well separated frequency regions. Moreover, it seems that it is possible to detect these failures by pure excore vibration measurements, what is important since incore vibration measurements are difficultly to be implemented over longer time periods. When measuring the displacements for x and y-direction even the localization of the failed guide lug might become achievable.

Altstadt, E.; Weiss, F.-P.

A finite-element-model describing the mechanical vibrations of the whole WWER-440 primary circuit was established to support the early detection of mechanical component faults. A special fluid-structure module was developed to consider the reaction forces of the fluid in the downcomer upon the moving core barrel and the rector pressure vessel. This fluid-structure interaction module is based on an approximated analytical 2D-solution of the coupled system of 3D fluid equations and the structural equations of motions. By means of the vibration model all igenfrequencies up to 30 Hz and the corresponding mode shapes were calculated. It is shown that the fluid-structure interaction strongly influences those modes that lead to a relative displacement between reactor pressure vessel and core barrel. Moreover, by means of the model the shift of eigenfrequencies due to the degradation or to the failure of internal clamping and spring elements was investigated. Comparing the frequency spectra of the normal and the faulty structure, it could be proved that a recognition of such degradations and failures even inside the reactor pressure vessel is possible by pure excore vibration measurements.

Finite element analysis of a BWR feed water distributor under extreme transient pressure load

Altstadt, E.; Ohlmeyer, H.; Otremba, F.; Weiss, F.-P.

During a hypothetical break of a BWR feed water line, the feed water distributor (FWD) inside the RPV is subjected to a high pressure load for a short time (10 ms). Because of the sudden coolant release from the inner volume of the FWD there is a pressure difference between the inner and outer surface. It is conservatively assumed that the pressure difference nearly can reach the operating pressure for a few milliseconds. The ring line of the feed water distributor is modelled with shell and volume elements capable of being used for large strain analyses with elastic-plastic material behaviour. It is demonstrated by non-linear static calculations (without consideration of the inertia of the material) that a buckling instability occurs at about 60% of the maximum pressure load. The arc-length method is used for the numerical solution to overcome this point of instability. To evaluate the influence of the dynamics of the process a non-linear transient analysis is done showing that the maximum strain occurs with a time delay to the pressure peak. The maximum plastic strain differs only nsignificantly between static and transient solution. Inspite of the large strains the mechanical integrity is maintained during the hypothetical event.

Keywords: BWR; Finite element analysis; Large strain; Plasticity; Transient analysis

Tritium depth profiling in carbon samples from fusion experiments

Friedrich, M.; Pilz, W.; Sun, G.; Behrisch, R.; Garcia-Rosales, C.; Bekris, N.; Penzhorn, R.-D.

Tritium depth profiling measurements by accelerator mass spectrometry have been performed at the facility installed at the Rossendorf 3 MV Tandetron. Hydrogen and deuterium profiles are measured with the Faraday cup between the injection magnet and the accelerator, while the tritium is counted after the accelerator with semiconductor detectors. Depth profiles have been measured for carbon samples which had been exposed to the D,D plasma at the first wall of the Garching fusion experiment ASDEX-Upgrade and from the European fusion experiment JET, Culham/UK, which had been operated part time with a D,T plasma. The tritium contents of the samples from JET were up to six orders higher compared to the samples from ASDEX-Upgrade. The problem of the detector overloading during measurements of samples with a medium tritium content has been solved by installation of a scanning system in the AMS beamline, which enables defined scanning of the tritium beam over an aperture in front of the detector. The tritium beam current from samples with high tritium content has been measured directly in the Faraday cup before the accelerator. A dedicated AMS facility with an air-insulated 100 kV tandem accelerator is under construction.

Fernüberwachung ukrainischer Kernkraftwerke (in Russisch)

Beyer, M.; Carl, H.; Schumann, P.; Seidel, A.

Die zu Beginn der neunziger Jahre in der Ukraine praktizierte Überwachung der Kernkraftwerke ermöglichte der Genehmigungs- und Aufsichtsbehörde nur einen unzureichenden Zugang zu Informationen über den jeweils aktuellen betrieblichen Sicherheitszustand.
Deshalb wurde für den 5. Block des KKW Saporoshje (WWER-1000/W-320) ein modernes betriebliches Überwachungssystem als Pilotprojekt konzipiert, eingerichtet und Ende 1995 in den Probebetrieb überführt. Es ergänzt die vorhandenen betrieblichen Kontroll- und Überwachungseinrichtungen durch Einbeziehung moderner informationstechnischer Mittel. Das System ermöglicht schwerpunktmäßig eine kontinuierliche Beobachtung des Zustandes vom Block 5 bei Normalbetrieb und bei Betriebsstörungen bzw. Störfällen, so daß bei erkennbaren Abweichungen vom bestimmungsgemäßen Anlagenbetrieb frühzeitig durch Nachfrage und Anordnung darauf reagiert werden kann.
Ein ähnliches Überwachungssystem konnte 1998 für den ersten und zweiten Block des KKW Rovno (WWER-440/W-213) eingerichtet und an das Informations- und Krisenzentrum in Kiew angeschlossen werden.

Astatine-211 production at the Rossendorf cyclotron

Guratzsch, H.

The production of Astatine-211 with the 120 cm Rossendorf cyclotron U-120 has been going on for two decades. Natural Bismuth evaporated on an Aluminium backing, a specially constructed water cooled target-block, is irradiated by 28 MeV Alpha-particles: 209Bi(Alpha, 2n)211At. For safety reasons the beam current is limited to 10 µA. The irradiated target is transported to the user who extracts the Astatine by himself. He also prepares the target with Bismuth for the next irradiation.

Keywords: Isotope production; Astatine-211; cyclotron; target construction

Pressure/composition isotherms of proton conducting SrYb0.05Zr0.95O2.975/H2O by means of nuclear resonance reaction analysis

Hempelmann, R.; Eschenbaum, J.; Altmayer, M.; Groß, B.; Grambole, D.; Herrmann, F.; Nagengast, D.; Krauser, J.; Weidinger, A.

Films of SrYb0.05Zr0.095O2.975 were prepared by sol-gel processing. Water vapour pressure/hydrogen composition isotherms were recorded ex-situ comprising
pressures between 0 and 84.5 kPa and temperatures between 873 and 1073 K. Nuclear Resonance Reaction Analysis (NRRA) was used to determine the
hydrogen concentration and, in addition, depth profiles of hydrogen concentration. The chemical potential of interstitial hydrogen in oxides could be determined; from
its temperature dependence thermodynamical constants were calculated. We observe two hydrogen fractions with a site energy difference of 20 kJ/mol. A size effect
of the thermodynamic properties is observed below a thickness of 350 nm: nanofilms exhibit higher solubility than bulk material.
