Already in 1998, the city of Hanover, the Stadtwerke Hannover and six further cities of the region initiated the funding programme 'Hannover proKlim' for promoting energy-relevant modernization measures in domestic buildings. One year later, the social marketing campaign 'Haus-Partner Hannover / Der (H)Eissbaer'' was started, which addresses building owners in Hanover with the intention to induce them to action. The 'Energiepass Hannover' is another important instrument of the campaign. This report takes stock of the results achieved so far. [German] Beim Klimaschutz im Gebaeudebestand lassen sich in Hannover drei Ansaetze hervorheben, die parallel zueinander entwickelt wurden und die in besonderer Weise dazu beitragen, die CO{sub 2}-Emissionen im Gebaeudebestand zu reduzieren: Bereits 1998 hat die Landeshauptstadt Hannover gemeinsam mit den Stadtwerken Hannover und sechs weiteren Staedten der Region den ...

Application of a gamma spectroscopy system to the measurement of neutron cross sections necessary to the development of nuclear energy; Mise au point d'un systeme de spectroscopie pour mesurer des sections efficaces neutroniques applicables a un possible developpement du nucleaire comme source d'energie

This work concerns the development of nuclear energy and nuclear waste management in particular. Two parts of this study can be distinguished. In the first part (theoretical), a thorium-plutonium fuel based on MOX and dedicated for PWR was investigated in order to transmute plutonium in a potentially low waste fuel cycle. It was shown that this type of fuel is not regenerative but could be used for a transition to the industrial thorium fuel cycle without building new reactors. Thanks to moderated neutron spectra and high loaded actinide mass in the core, U-233 is quickly created ({approx}300 kg/y) for a loss of about {approx}1200 kg of fissile plutonium. In the second part (experimental), we have developed and built a new reaction chamber to measure neutron cross sections of actinides by alpha-gamma spectroscopy. This experimental device (in principle transportable) was commissioned in the high flux reactor of ILL Grenoble. Neutron flux was measured by gamma spectroscopy of irradiated ...
