Proposta de programa de garantia da qualidade para uma organização de manutenção e apoio ao submarino convencional com propulsão nuclear

Abstract

A quality assurance system is the set of systematic measures developed to provide adequate confidence that a structure, system, component or installation, will work safely. This system is described in a document called a quality assurance program. Currently, there is no standard aimed at establishing requirements for a quality assurance program aimed at an installation that performs maintenance, repair and support activities for the conventional nuclear-powered submarine. This work aims to propose a quality assurance program for a naval base, which meets the requirements of nuclear and naval safety. The implementation of this program is essential for the nuclear installation to obtain the operating license from the licensing agency. To achieve the objectives, bibliographic research, documentary research and field research at the Nuclear Power Plant in Angra I were used. The latter consisted of observations by the researcher, collection of documents and interviews with professionals in the nuclear sector. As a consequence of the research carried out, this work highlighted the particular characteristics of a naval base and the scope of the quality assurance programs of the nuclear sector. The project also showed that the quality assurance program of the Angra I Nuclear Plant has additional requirements not foreseen in the rules of the regulatory body. The interviews conducted in this work clarified that it is possible to propose a quality assurance program based on the program used at the Angra I Nuclear Plant with the necessary adaptations. As a result, a quality assurance program with 13 additional requirements to the CNENNN- 16 standard was proposed in this work, totaling 25 requirements. This program was validated through interviews with specialists in the sector and should be part of the licensing process for the Naval Base. Once this program is implemented, control over activities that affect the quality of equipment, systems, components, etc. of the Naval Base that influence the nuclear safety of the installation and submarine will be ensured, contributing to the preservation of the lives of employees, crew, society and the environment.
