Purpose
 Present the main achievements, research and studies
in progress at the Instituto de Engenharia Nuclear
(IEN), Nuclear Engineering Institute in English.

3. 3
Presentation
 The Instituto de Engenharia Nuclear (IEN) is a research and development
unit of the Comissão Nacional de Energia Nuclear (CNEN), the Brazilian
Nuclear Energy Commission, of the Ministry of Science, Technology and
Innovation (MCTI). IEN is located in Rio de Janeiro city;
 The Institute has recently celebrated its 58th year of existence, time during
which it contributed significantly to the development of Nuclear Science
and Technology in Brazil.

IEN’s research activities
 The Reactor Engineering and Thermo-hydraulics Service develops
theoretical and applied research in nuclear reactor physics and thermo-
hydraulics for both power and research reactors.
 Argonauta Reactor Service provide major contributions to training and
formation in the nuclear domain. There are also a number of ongoing
research activities regarding radiographic imaging using the reactor neutron
flux, and the non-destructive testing of mechanical components.

 The Nuclear Materials Service develops research on ultrasonic techniques
for stress analysis and ultrasonic characterization of nuclear fuels.
 The Chemical and Radioactive Waste Service performs activities regarding
storage and management of radioactive waste and chemical analysis.
 The Instrumentation Service develops nuclear instrumentation (reactor
instrumentation, radiation protection and nuclear medicine equipment) and
electronic maintenance.

 The Radiopharmaceuticals Division maintains a routine production of 18-
FDG, 123-MIBG and Ultra-pure 123-I. The existing facility, includes two
cyclotrons (a CV-28 and RDS Eclipse), and a radiochemistry laboratory.
 The Complex System Engineering service develops research on:
- human-system interfaces
- human reliability
- artificial intelligence and fuzzy models for nuclear process, safety and
resilience engineering
- virtual reality applied to control room designing and nuclear facilities
security
- knowledge management (KM)

This research group studies strategic solutions for the
preservation, sharing and diffusion of the knowledge produced at
IEN, having as a guiding element the country's scientific and
technological development in the nuclear area.

Main achievements
1. The CarpeDIEN Platform
 Institutional repository of information and research data of
IEN: theses, scientific data, technical-scientific publication,
administrative documents, historical documents, presentations,
and other digital objects;
 Techniques and methodologies were used to represent and
preserve data and information in digital form: Digital Curation of
Research Data;
 Web application based on the DSpace software. DSpace is an
open source repository software package typically used for
creating open access repositories for scholarly and/or published
digital content.

Main achievements
1. The CarpeDIEN Platform
 This platform integrates since the end of July 2014 the world
ranking of digital repositories produced by Cybermetrics Lab, a
group linked to the Higher Council for Scientific Research in
Spain (CSIC, in the acronym in Spanish), the largest public
research organization in that country.

Main achievements
2. WikiIEN
 This tool aims to improve the sharing of information among
institute researchers, thorough a dynamic common knowledge
base that can be on-line updated.
 Wiki-type web application based on the MediaWiki software.
MediaWiki is a free, open-source wiki-type web application
widely used. Wikipedia is the most famous website that uses
MediaWiki;
 All users are required to login to be able to create / edit articles
(mathematical formula, images and videos), a relevant point
because of the application’s serious purpose in a research institute.

14. 14
2. WikiIEN
 The content is focused on nuclear knowledge and/or IEN-related;
 Its purpose is to enable the users to write new article and to
improve the existing ones collaboratively, in order to preserve the
knowledge of workers and collaborators.

3. Progress Report
 Academic journal that publishes articles about scientific
research accomplished by IEN.
 It is based on the Open Journal Systems (OJS) software.
OJS is an open source software application for managing and
publishing scholarly journals.
 Current edition of Progress Report highlights the research and
development in the period 2018-2019.

Research and studies in progress
1. A Fuzzy Decision Making Method for KM
1. Determination of a framework of critical success factors (CSFs) in order to
be able to monitor the success of a knowledge management initiative;
2. This framework is based on seven themes: top-level commitment,
organizational culture, organizational structure, human resources
management practices, measuring and results, information technology and
learning culture;
3. The use of properties of fuzzy logic (mathematics) to model of critical
success factors. Fuzzy logic used to deal with uncertainty and
imprecision of human judgment assessing CSFs.
4. Prioritization of CSFs to serve as a pattern for the KM assessments;
5. Assessment of KM based on the ideal KM pattern.
