A Study of the Disaster Prevention and Protectim System in Taiwan with the Local Government¡¦s Nuclear Accident Emergency Response as an Example

Chian-Hsin, Chang 03 August 2004 (has links)
In the aftermath of the nuclear accidents at Chernobyl in Russia, at the Three Mile Island reactor in the United States and the nuclear criticality accident at the Tokai-mura JCO in Japan, the need for serious attention has been directed toward response planning for nuclear emergencies. Currently Taiwan has one of the highest population densities in the world. To handle energy needs, there are three nuclear facilities. Recently the first serious electrical failure occurred at the third nuclear reactor (3A). This incident in particular brought the need for proper measures to handle accidents to the attention of the public. The main purpose of this thesis is to investigate the effectiveness of the national planning for handling nuclear emergencies under the existing laws for nuclear accident emergency response and the laws for disaster prevention at the local government level. Attention is given to the capability of the design and organizational system for handling nuclear emergencies and whether this plan can be realized in actual practice. Having reached a thorough understanding through the analysis, the paper makes suggestions about the procedures to be followed for the national government¡¦s handling of nuclear plant emergencies.

Uso de ambientes virtuais para a simulação de acidentes radiológicos / Use of virtual environments to simulate radiological accidents

Tadeu Augusto de Almeida Silva 26 June 2012 (has links)
Em um ambiente virtual, construído com o uso de tecnologia computacional, encontram-se presentes entidades virtuais inseridas em um espaço tridimensional, que é utilizado para a simulação de processos críticos, como os acidentes radiológicos. A pronta detecção de um acidente radiológico e a determinação da sua possível extensão são fatores essenciais para o planejamento de respostas imediatas e de ações de emergência. A integração das representações georeferenciadas do espaço tridimensional, com modelos baseados em agentes autônomos, com o objetivo de construir ambientes virtuais que tenham a capacidade de simular acidentes radiológicos é a proposta dessa tese. As representações georeferenciadas do espaço tridimensional candidatas são: i)as representações espaciais usadas nos sistemas de informações geográficas (SIG) e ii) a representação adotada pelo Google MapsTM. Com o uso deste ambiente pode-se: quantificar as doses recebidas pelas pessoas; ter uma distribuição espacial das pessoas contaminadas; estimar o número de indivíduos contaminados; estimar o impacto na rede de saúde; estimar impactos ambientais; gerar zonas de exclusão; construir cenários alternativos; treinar pessoal técnico para lidar com acidentes radiológicos. / In a virtual environment, built with the use of computer technology, there are virtual entities, inserted into a virtual three-dimensional space, which is used to simulate critical processes, such as radiological accidents. Early detection of a radiological accident and determining its possible extension are essential for planning an immediate response and emergency actions. The purpose of this thesis is to build virtual environments that have the ability to simulate radiological accidents. These virtual environments are based on the integration of georeferenced representations of the three dimensional space with autonomous agents-based models. The georeferenced representations candidates are: i) the spatial representation used in geographic information systems (GIS); ii) the representation adopted by Google MapsTM. Using these virtual environments, in case of occurrences of radiological accidents, it will be possible to quantify the doses received by people, have a spatial distribution of infected persons; estimate the number of infected individuals; estimate the impact on the health network, estimate environmental impacts, generate exclusion zones, building scenarios alternative; train staff for dealing with these accidents.
