Converting Maturing Nuclear Sites to Integrated Power Production Islands

Nuclear power programme planning: An integrated approach

FOREWORD The International Atomic Energy Agency (IAEA) has published material on different policy considerations in the introduction of nuclear power, primarily addressed to top level decision makers in government and industry in Member States. Several Member States and experts recommended to the IAEA to address the aspects of an integrated approach to nuclear power programme planning and to se...

Solid wastes from nuclear power production.

Radioactivity in nuclear power effluents is negligible compared to that in retained wastes to be disposed of as solids. Two basic waste categories are those for which shallow disposal is accepted and those for which more extreme isolation is desired. The latter includes "high level" wastes and others contaminated with radionuclides with the unusual combined properties of long radioactive half-l...

Optimal design of reliable integrated chemical production sites

Since plants that form the network are subject to fluctuations in product demand or random mechanical failures, design decisions such as adding redundant units and increasing storage between units can increase the flexibility and reliability of an integrated site. In this paper, we develop a bi-criterion optimization model that captures the trade-off between capital investment and process robus...

Histamine regulates cytokine production in maturing

Naive CD4+ T cells differentiate into Th1 or Th2 subsets, characterized by the release of distinct patterns of cytokines. Th1 cells produce IFN-γ and TNF-β, which promote cell-mediated immunity, while Th2 cells secrete IL-4, IL-5, IL-6, IL-9, IL-10, and IL-13, which favor humoral responses (1). The polarization of naive T cells toward Th1 or Th2 phenotypes is mediated primarily by dendritic cel...
