edge at the national level. It was found that, in general, there were changes in thermophysical
properties analyzed as function of volumetric concentrations and as function of temperatures
tested. Similarly, it was not proven significant changes in the physical structure of the nano-
composites tested, although images showed apparently particles modifications or agglomera-
tions. The results of the investigations are important to the development of knowledge of the
behavior of nanofluids under the action of ionizing radiation, making it possible, in the future,
its applications in new generations of nuclear reactors, in addition to contributing to the de-
velopment of knowledge and training of new researchers in the area of nanotechnology and
nuclear in Brazil. Figure 1 shows the nanofluids samples before and after irradiation, and Fig
2 shows the SEM image of the nanoparticles investigated. This project received funding from
the Regular Research Projects Call - FAPESP n. 2013/11703-2.

Digital radiographic images analysis applied to the nuclear plate type fuel of RMB

Figure 25. Digital radiographic image of the plate type fuel.

The radiographic images used to control the quality of the fuel plates produced for the IEA-R1,
as well as the core exchange of the IPEN / MB-01 reactor, and in the future in the RMB, are now
digitally processed, allowing a precise analysis of the homogeneity in the distribution of the
aluminum mixture with uranium silicide composing them. This analysis is part of a method-
ology under development at the Nuclear Engineering Center in conjunction with the Nuclear
Fuel Center. Figure 1 shows the digital radiographic image of the plate type fuel.

IAEA-CRP: Nuclear Security Culture - Application of Systems Theoretic Process Analysis (STPA)
to evaluate the culture of security in nuclear installations and its effects on safety. This work
aims at practical applications and will be done with the study of real cases of incidents involv-
ing “insiders”. It will also have applications in aspects of: Cyber Security, Physical Protection,
Intruders and Terrorism.

ITA Computer Department. Work aimed at applying STPA for safety analysis in high risk indus-
tries such as nuclear and aeronautics. Security aspects involving computerized controls, espe-
cially embedded software in the case of aircraft and automated controls in nuclear plants (ac-
tivity being formalized), will be studied.

Collaboration with CTMSP. Study of the effects of electromagnetic interference on the safety
of nuclear installations (activity under analysis).
