Title in Portuguese
Aplicação da técnica de análise de modos de falha e efeitos ao sistema de resfriamento de emergência de uma instalação nuclear experimental
Keywords in Portuguese
AMFE
Análise de Risco
SRE
Abstract in Portuguese
Este trabalho consiste em aplicar a técnica de identificação de perigos e análise de risco conhecida como Análise de Modos de Falha e Efeitos (AMFE) ao Sistema de Resfriamento de Emergência (SRE) de uma instalação nuclear experimental, cuja função é a de mitigar as conseqüências de um eventual acidente de perda de refrigerante no circuito primário de um reator a água pressurizada. Esse tipo de análise tem como objetivo identificar as possíveis vulnerabilidades desse sistema e propor melhorias de modo a maximizar sua confiabilidade. Para isso foi realizado o estudo detalhado do sistema (por intermédio de sua documentação técnica), obtido o diagrama de blocos correspondente, feita a análise do tipo AMFE e, finalmente, apresentadas algumas sugestões.

Abstract in English
This study consists on the application of the Failure Modes and Effects Analysis (FMEA), a hazard identification and a risk assessment technique, to the Emergency Cooling System (ECS) of an experimental nuclear power plant, which is responsible for mitigating the consequences of an eventual loss of coolant accident on the Pressurized Water Reactor (PWR). Such analysis intends to identify possible weaknesses on the design of the system and propose some improvements in order to maximize its reliability. To achieve this goal a detailed study of the system was carried on (through its technical documentation), the correspondent reliability block diagram was obtained, the FMEA analysis was executed and, finally, some suggestions were presented.
