AbstractAbstract
[en] Many existing MCA and multi channel scaling (MSC) systems are physically large or plug-in cards thus require both a personal computer and proper measure instruments. Their main disadvantage is large weight and difficult mobility. As so, our motivation was to develop a compact, lightweight and mobile, fully feature PC radioactive spectrometry system. We have developed a portable spectrometry system which includes MCA, MSC, High Voltage Power Suppliers (HVPS), a laptop and all other components needed for spectroscopy measurement. One of the developed system's advantages is the ability to connect wide range of radiation detectors

AbstractAbstract
[en] Starting from the lump-sum criterion of distance, the criterion of MCA has developed based on the idea of limiting accident consequences with the object in mind of guaranteeing the protection of the population in case of the maximum credible accident in its absolute sense. This claim has proved to be indefensible for the utilization and design of the MCA criterion on nuclear power plants of larger capacities on sites near to conurbation centres. Within the concept of design basis accidents this is not claimed, an imperative formulation was found instead concerning the sort of accident to be considered, including possible demands on its safety design. Using probability methods has lead to a blurring of the relationship with the technological system of nuclear power plants for formulating a criterion for the advantage of risk quantification. If the probability method is to be applied in the licensing procedure concerning nuclear power plants it will be one of the tasks of future safety research to elaborate this relationship clearly.

Ausgehend von dem pauschalen Abstandskriterium hat sich auf der Basis der Idee von der Begrenzung der Stoerfallfolgen das Kriterium des GaU entwickelt. Dies mit der Zielsetzung, den Schutz der Bevoelkerung fuer den groessten erdenklichen Stoerfall im absoluten Sinne zu gewaehrleisten. In der Anwendung und Auslegung des GaU-Kriteriums auf KKW groesserer Leistung in zivilisationsnahen Standorten erwies sich dieser Anspruch als nicht haltbar. Innerhalb des Konzeptes der Auslegungsstoerfaelle wird dieser Anspruch nicht erhoben, statt dessen findet man eine imperative Formulierung, welche Art von Stoerfaellen zu betrachten sind, unter Einschluss moeglicher Anforderungen an die sicherheitstechnische Auslegung. Mit der Anwendung probabilistischer Methoden ist nun um den Vorteil der Quantifizierung des Risikos der Bezug zum technologischen System Kernkraftwerk fuer die Formulierung eines Kriteriums undeutlich geworden. Wenn die probabilistische Methodik Anwendung in der Genehmigung von Kernkraftwerken finden soll, wird es eine Aufgabe der zukuenftigen Sicherheitsforschung sein, diesen Bezug deutlich herauszuarbeiten.

AbstractAbstract
[en] Chronic inflammation plays a key tumor-promoting role in lung cancer. Our previous studies in mice demonstrated that neutrophils are critical mediators of tumor promotion in methylcholanthrene (MCA)-initiated, butylated hydroxytoluene (BHT)-promoted lung carcinogenesis. In the present study we investigated the role of neutrophil myeloperoxidase (MPO) activity in this inflammation promoted model. Increased levels of MPO protein and activity were present in the lungs of mice administered BHT. Treatment of mice with N-acetyl lysyltyrosylcysteine amide (KYC), a novel tripeptide inhibitor of MPO, during the inflammatory stage reduced tumor burden. In a separate tumor model, KYC treatment of a Lewis Lung Carcinoma (LLC) tumor graft in mice had no effect on tumor growth, however, mice genetically deficient in MPO had significantly reduced LLC tumor growth. Our observations suggest that MPO catalytic activity is critical during the early stages of tumor development. However, during the later stages of tumor progression, MPO expression independent of catalytic activity appears to be required. Our studies advocate for the use of MPO inhibitors in a lung cancer prevention setting

AbstractAbstract
[en] The course of a hypothetic transient overpower accident caused by the onset of a not further specified reactivity ramp accompanied by the simultaneous failure of both shutdown systems must be analyzed in the SNR 300 Mark 1A core licensing procedure. The present study is limited to the discussion of the starting and shutdown phases of such accidents for the fresh core. Depending on the operational state of the reactor, the core geometry is still intact during the starting phase. In the following shutdown phase (core disassembly phase), large-scale mass transfer leads to the nuclear shutdown of the reactor. (orig./AK)

Der Verlauf eines hypothetischen Leistungsstoerfalles, der sich durch Einlaufen einer von der Ursache her nicht naeher spezifizierten Einleitungsreaktivitaetsrampe bei gleichzeitigem Versagen beider Abschaltsysteme ergibt, muss im Genehmigungsverfahren des SNR 300 Mark 1A Kerns analysiert werden. Die vorliegende Studie beschraenkt sich auf die Diskussion der Einleitungs- und Abschaltphase solcher Stoerfaelle fuer den frischen Kern. Ausgehend vom Betriebszustand des Reaktors verlaeuft die Einleitungsphase bei noch intakter Kerngeometrie. In der dann folgenden Abschaltphase (Kernzerlegungsphase) fuehren groessere Materialbewegungen zur nuklearen Abschaltung des Reaktors. (orig./RW)Original Title

AbstractAbstract
[en] Sandia National Laboratories is conducting a hydrogen research program for the U. S. Nuclear Regulator Commission. The program has two major objectives: assessment of the threat to nuclear power plants (containment structure, safety and control equipment, and the primary system) posed by hydrogen combustion; and assessment of proposed hydrogen control and disposal methods, and development of new concepts. This paper discusses the major program elements, recent research results, and future plans. (orig.)

AbstractAbstract
[en] In reactors of the WWER-440 and WWER-1000 type the maximum credible accident is the rupture of the biggest piping of the biggest diameter in the primary circuit, i.e., pipes having a diameter of 500 mm in the former type and 850 mm in the latter type. The reactor protection system which includes reserve high- and low-pressure pumps and large-volume water tanks is therefore dimensioned in such a manner as to prevent radioactivity leak even in such a case. For such an event transients caused by coolant loss were computed and the theoretical aspects of the problem processed. Also described and schematically represented is the entire equipment of the WWER-440 designed for the elimination of such an accident. (O.K.)
