  1. 6. Sensitivity and Uncertainty Analysis of Boiling Water Reactor Stability Simulations

    Författare :Ivan Gajev; Weimin Ma; Tomasz Kozlowski; Kostadin Ivanov; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BWR Stability; Sensitivity; Uncertainty; SRA - Energy; SRA - Energi;

    Sammanfattning : The best estimate codes are used for licensing of Nuclear Power Plants (NPP), but with conservative assumptions. It is claimed that the uncertainties are covered by the conservatism of the calculation. LÄS MER

  3. 7. Hereditary breast and ovarian cancer in western Sweden with a special focus on BRCA1 3171ins5 mutation

    Författare :Zakaria Einbeigi; Göteborgs universitet; []
    Nyckelord :BRCA1 gene; breast neoplasm; ovarian neoplasm; hereditary; haplotype;

    Sammanfattning : Aims: To describe the phenotype and geographic distribution of the western Swedish founder mutation BRCA1 3171ins5, evaluate the reliability of mutation analysis of this mutation on archival material, analyse the haplotype for founder effects in families with BRCA1 3171ins5 mutation, estimate the age of this mutation and evaluate whether the occurrence of both breast and ovarian cancers in the same women may be a marker of a BRCA gene mutation. Materials and methods: The first study was based on 16 families with BRCA1 3171ins5 mutation and the second study was based on 18 families with the same mutation. LÄS MER

  4. 8. Etiologic, diagnostic and prognostic factors in vulvar cancer

    Författare :Gunnel Lindell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :sentinel node biopsy;

    Sammanfattning : Vulvar Squamous Cell Carcinoma (VSCC) can be divided into two subgroups basaloid and/or warty (HPV-associated) and keratinizing/non-keratinizing carcinomas (not HPV-associated). The inguinal lymph node status represents the most powerful prognostic factor. LÄS MER

  5. 9. Nuclear data uncertainty quantification and data assimilation for a lead-cooled fast reactor : Using integral experiments for improved accuracy

    Författare :Erwin Alhassan; Henrik Sjöstrand; Rochman Dimitri; Michael Österlund; Stephan Pomp; Oscar Cabellos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Total Monte Carlo; ELECTRA; nuclear data; uncertainty propagation; integral experiments; nuclear data adjustment; uncertainty reduction;

    Sammanfattning : For the successful deployment of advanced nuclear systems and optimization of current reactor designs, high quality nuclear data are required. Before nuclear data can be used in applications they must first be evaluated, tested and validated against a set of integral experiments, and then converted into formats usable for applications.

  7. 10. Uncertainty and Sensitivity Analysis Applied to the Validation of BWR Bundle Thermal-Hydraulic Calculations

    Författare :Augusto Hernandéz Solís; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Latin Hypercube sampling; uncertainty and sensitivity analysis; Thermal‐hydraulic codes; simple random sampling; reactor safety analysis; BFBT benchmark;

    Sammanfattning : In recent years, more realistic safety analyses of nuclear reactors have been based on best estimate (BE) computercodes. The need to validate and refine BE codes that are used in the predictions of relevant reactor safetyparameters, led to the organization of international benchmarks based on high quality experimental data.
