  • The neutron resonance phenomena constitute one of the most fundamental subjects in nuclear physics as well as in reactor physics. It is the area where the concepts of nuclear interaction and the treatment of the neutronic balance in reactor lattices become intertwined. The later requires the detailed knowledge of resonance structures of many nuclide of practical interest to the development of nuclear energy. The key issue of the resonance treatment in reactor applications is directly associated with the use of the microscopic cross sections in the macroscopic reactor cells with a wide range of composition, temperature,and geometric configurations. It givesmore » rise to the so called self-shielding effect. The accurate estimations of such a effect is essential not only in the calculation of the criticality of a reactor but also from the point of view of safety considerations. The latter manifests through the Doppler effect particularly crucial to the fast reactor development. The task of accurate treatment of the self-shielding effect, however, is by no means simple. In fact, it is perhaps the most complicated problem in neutron physics which, strictly speaking, requires the dependence of many physical variables. Two important elements of particular interest are : (1) a concise description of the resonance cross sections as a function of energy and temperature; (2) accurate estimation of the corresponding neutron flux where appropriate. These topics will be discussed from both the historical as well as the state-of-art perspectives.« less
  • A report is presented on a recent visit to Venezuela and Brazil to investigate their national programs directed toward the development of heavy oil and alcohol fuels respectively. The delegation had the opportunity to talk with the responsible government officials, the industry participants and the researchers in the field. Venezuela has made a national commitment to develop their extensive heavy oil reserves. With conventional oil wells declining in production, heavy oil promises to make an important contribution to their total oil production in the next 20 years. Venezuela's National Technological Institute of Petroleum has the important task of research onmore » the recovery and upgrading of heavy crudes from the Orinoco Oil Belt and the Maracaibo Basin. It is their hope that this research will open the way for the production and sale of these heavy crudes. Although Venezuela's long-term oil future appears stable, they have a carefully planned program of investments of more than $18.7 billion over the next 10 years to assure their production levels. Brazil has made a similar aggressive commitment to the development and utilization of alcohol fuels. With 85% dependence on imported oil, Brazil decided in 1975 to make an all-out effort to reduce imports and utilize their sugar stocks to produce alcohol for their transportation sector. Their first phase goal of achieving a 20% alcohol-gasoline blend has already been met. Their next phase calls for the use of 100% alcohol-fueled vehicles and a production goal of 2.8 billion gallons by 1985. Not only is the government committed to this goal, but so also is the private sector. The several largest automobile manufacturers have cooperatively agreed to manufacture over 1 million cars in the next 3 years which will run on 100% alcohol.« less
