The thesis is mainly focused on the design of the intermediate heat exchanger primary circuit of the reactor ESFR. Heat exchanger is calculated heat, hydraulic and strength and is finally processed part drawings. There are designed the basic dimensions of the tube bundle and container heat exchanger. There are included an overview of concepts and so far used types IHX at the nuclear power plants with fast reactors. There are also mentioned basic parameters of the project ESFR and evaluated the safety and operational reliability of the heat exchanger.

This dissertation covers the application of heat accumulation systems in nuclear power engineering, namely in nuclear power plants. It is mainly a case of passive emergency systems, whose task is to accumulate the heat produced in the reactor’s active zone and in spent fuel pools during DBA (design-basis accidents) or beyond DBA. A particular example of heat accumulation is steam condensation after LOCA (loss of coolant accident). The primary circuit steam leakage increases containment pressure and has to be decreased by the steam condensation. This thesis deals with a theoretical substitute for ice condensers, which are used as a passive safety measure in some nuclear power plants. The substitute involves a choice of an alternative material, whose melting temperature (for heat accumulation) is closer to nuclear power plant operating temperatures. The other part of the dissertation discusses heat accumulation in spent fuel pools in case of all cooling systems failure.

Werden Defizite in Bewässerungssystemen als rein technisches Problem betrachtet, führt dies zur Ausblendung sozialer und kultureller Aspekte der Ressourcenverwaltung. Als Konsequenz werden sinnvolle technische Innovationen von der Bevölkerung nicht angenommen und verbleiben letztendlich ungenutzt. Bisherige Studien über das südmarokkanische Oasengebiet im Ziz-Tal hatten überwiegend ökologische und ingenieurtechnische Ansätze verfolgt. Das Forschungsinteresse dieser Arbeit liegt stärker auf den kollektiven Handlungsmustern, Regelsystemen und spezifischen Variationen sozialer Vereinbarungen in Form von formellen und informellen Institutionen der traditionellen und der heutigen Bewässerung. Zum Verständnis der gegenwärtigen Situation werden die rechtlichen und politischen Rahmenbedingungen, der soziokulturelle Kontext sowie die naturräumlichen Voraussetzungen und Umweltveränderungen – mit besonderem Blick auf die verfügbaren Wasserressourcen in dieser ariden Region – analysiert und das institutionelle Gefüge in einer auf Methoden der qualitativen Sozialforschung basierenden Fallstudie in einem Oasendorf untersucht.

Många av Sveriges badhus byggda i slutet av 1900-talet börjar idag visa tecken på kraftiga fuktskador på grund av extrema inomhusklimat. Denna rapport förklarar den allmänna problematiken kring högt fuktbelastade byggnader och berör det fuktskadade badhuset Aquarena i Katrineholm.  Extrem noggrannhet krävs vid montering av ångspärr i en konstruktion, speciellt vid högt invändigt fukttillskott. Optimal placering av fuktspärren i konstruktionens varmare del innebär att fukt aldrig tillåts kondensera och därmed minimeras risken för fuktskador och negativa konsekvenser. Verkligheten visar också att om kunskaper om fukt och fuktskador prioriteras redan i ett tidigt stadium under projektering kan många hundratusentals kronor sparas. Beräkningar av fukttransport har gjorts för tidigare ytterväggskonstruktion i Aquarena (den som drabbats av skador) och nybyggd ytterväggskonstruktion (nyframtagen till återuppbyggnaden) i datorprogrammet WUFI Pro 4.2 och analyserats i WUFI Bio 3.0.  Beräkningarna visar att den tidigare väggkonstruktionen får de skador som undersökningar av den visat och att skadorna hade kunnat undgås om genomförningar i ångspärren hade utförts på ett korrekt sätt.  Vi har med beräkningar inte kunnat bevisa att alla delar i den nybyggda ytterväggskonstruktionen kommer fungera perfekt. Främst beror osäkerheten i beräkningar utförda i WUFI på att beräkningsmodellen inte är färdigutvecklad. Osäkerheter beror också på otillräcklig kännedom av egenskaper hos de simulerade materialen. Beräkningar för den nyframtagna väggkonstruktionen visar dock entydigt på bättre resultat än för den tidigare väggkonstruktionen. Det finns därför anledning att vidare utreda vilka värden på fukt och temperatur som kommer att råda över de närmaste åren. Detta bland annat för att senare kunna korrigera beräkningsmodellen efter verkligheten. / Many of Sweden's public indoor swimming pools built in the late 1900’s are beginning to show signs of excessive moisture damage due to extreme indoor climate. This report explains the general problem of high moisture-loaded buildings and involves the moisture-damaged public indoor swimming pool Aquarena in Katrineholm. Extreme care is required when assembling the moisture barrier in a structure, especially with high internal moisture content. Optimal placement of the moisture barrier in the warmer parts of the construction means that moisture is never allowed to condense, thus minimizing the risk of moisture damage and negative consequences. Reality also shows that if risks of moisture and moisture damages are assessed early in the planning process, amounts in the range of hundreds of thousands of Swedish crowns can be saved. Calculations of moisture transport have been made for the previous exterior wall structure (the one that suffered damage) and new exterior wall structure the (new design for the reconstruction) using the computer program WUFI Pro 4.2 and analyzed in WUFI Bio 3.0. Calculations show that the old exterior wall structure in Aquarena would have been able to withstand moisture damage and damages due to moisture if joints and transitions in the moisture barrier had been correctly performed.  Calculations have not proven that all elements of the newly built wall design will work perfectly. The main reason for uncertainty in calculations when using WUFI is that the calculation model is not fully developed. Uncertainty is also due to insufficient knowledge of properties of the simulated materials. However, calculations show unambiguously better results than the previous wall construction. It is therefore necessary to further investigate what values of humidity and temperature will exist over the next few years to be able to later on correct the calculation model after reality.

This thesis deals with the engineering of novel nanomaterials, particularly nanocomposites and nanostructured surfaces with enhanced functionalities. The study includes two parts; in the first part, an in situ sol-gel polymerization approach is used for the synthesis of polymer-inorganic hybrid material and its exceptional transparent UV-shielding effect has been investigated. In the second part, electrodeposition process has been adapted to engineer surfaces and the boiling performance of the fabricated nanostructured surfaces is evaluated. In the first part of the work, polymer-inorganic hybrid materials composed of poly(methylmethacrylate) (PMMA) and zinc compounds were prepared by in situ sol-gel transition polymerization of zinc complex in PMMA matrix. The immiscibility of heterophase of solid organic and inorganic constituents was significantly resolved by an in situ sol-gel transition polymerization of ZnO nanofillers within PMMA in the presence of dual functional agent, monoethanolamine, which provided strong secondary interfacial interactions for both complexing and crosslinking of constituents. In the second part of the work, nanoengineering on the surface of copper plates has been performed in order to enhance the boiling heat transfer coefficient. Micro-porous surfaces with dendritic network of copper nanoparticles have been obtained by electrodeposition with dynamic templates. To further alter the grain size of the dendritic branches, the nanostructured surfaces underwent a high temperature annealing treatment. Comprehensive characterization methods of the polymer-inorganic hybrid materials and nanoengineered surfaces have been undertaken. XRD, 1H NMR, FT-IR, TGA, DSC, UV-Vis, ED, SEM, TEM and HRTEM have been used for basic physical properties. Pool boiling tests were performed to evaluate the boiling performance of the electrodeposited nanostructured micro-porous structures. The homogeneous PZHM exhibited enhanced UV-shielding effects in the entire UV range even at very low ZnO content of 0.02 wt%. Moreover, the relationship between band gap and particle size of incorporated ZnO by sol-gel process was in good agreement with the results calculated from the effective mass model between bandgap and particle size. The fabricated enhanced surface has shown an excellent performance in nucleate boiling. At heat flux of 1 W/cm2, the heat transfer coefficient is enhanced over 15 times compared to a plain reference surface. A model has been presented to explain the enhancement based on the structure characteristics. / QC 20101118
