New Curriculum

Há um grande interesse em restringir a ampla gama e vasto domínio dos possíveis temas que poderiam ser ensinados sobre astronomia em uma estrutura gerenciável. Embora não haja nenhum currículo nacional obrigatório nos Estados Unidos, uma análise dos três esforços nacionais recentes para criar uma sequência apropriada de conceitos de astronomia por idade para serem ensinados nas escolas primárias e secundárias revela uma considerável falta de consenso a respeito de quais conceitos são mais apropriados para cada idade e quais tópicos devem ser cobertos. O esquema de padronização mais recente para a educação científica dos EUA, o Next Generation Science Standards (Padrões em Ciência: Nova Geração), sugere que a maioria dos conceitos de astronomia devem ser ensinados apenas nos últimos anos de educação do aluno; e no entanto  foi recebido com críticas consideráveis. Uma comparação dos esquemas de aprendizagem da astronomia nos Estados Unidos e uma breve discussão das críticas levantadas podem proporcionar aos educadores de astronomia internacionais dados de comparação na formulação de recomendações em suas próprias regiões.

The phenomenal growth of penal confinement in the United States in the last quarter of the twentieth century is still a public policy mystery. Why did it happen when it happened? What explains the unprecedented magnitude of prison and jail expansion? Why are the current levels of penal confinement so very close to the all-time peak rate reached in 2007? What is the likely course of levels of penal confinement in the next generation of American life? Are there changes in government or policy that can avoid the prospect of mass incarceration as a chronic element of governance in the United States? This study is organized around four major concerns: What happened in the 33 years after 1973? Why did these extraordinary changes happen in that single generation? What is likely to happen to levels of penal confinement in the next three decades? What changes in law or practice might reduce this likely penal future?

The United States Department of Energy’s Next Generation Nuclear Plant (NGNP) Advanced Gas Reactor (AGR) Fuel Development and Qualification Program will be irradiating up to nine low enriched uranium (LEU) tri-isotopic (TRISO) particle fuel (in compact form) experiments in the Advanced Test Reactor (ATR) located at the Idaho National Laboratory (INL). The ATR has a long history of irradiation testing in support of reactor development and the INL has been designated as the United States Department of Energy’s lead laboratory for nuclear energy development. These irradiations and fuel development are being accomplished to support development of the next generation reactors in the United States, and the irradiations will be completed over the next five to six years to support demonstration and qualification of new TRISO coated particle fuel for use in high temperature gas reactors. The goals of the irradiation experiments are to provide irradiation performance data to support fuel process development, to qualify fuel for normal operating conditions, to support development and validation of fuel performance and fission product transport models and codes, and to provide irradiated fuel and materials for post irradiation examination (PIE) and safety testing. The experiments, which will each consist of multiple separate capsules, will be irradiated in an inert sweep gas atmosphere with individual on-line temperature monitoring and control of each capsule. The sweep gas will also have on-line fission product monitoring on its effluent to track performance of the fuel in each individual capsule during irradiation. The first experiment (designated AGR-1) started irradiation in December 2006 and completed a very successful irradiation in early November 2009. The second experiment (AGR-2) is currently being fabricated and assembled for insertion in the ATR in the early to mid calendar 2010. The design of test trains, the support systems and the fission product monitoring system used to monitor and control the experiment during irradiation will be discussed. In addition, the purpose and differences between the first two experiments will be compared, and updated information on the design and status of AGR-2 is provided. The preliminary irradiation results for the AGR-1 experiment are also presented.
