Preservation of knowledge through networking with retirees
2010 - BARROSO, A.C.O.; REIS-JUNIOR, J.S.B.; MONTEIRO, C.A.; SEARY, A.
Nuclear organizations, in most countries, have for many years endured a process of a reducing workforce and of a shift of the average age of their technical professionals towards the mid fifties range. Loss of emphasis or phasing down of their nuclear programs has reduced substantially the hiring of new employees. As a result some knowledge management activities with emphasis on knowledge preservation have been undertaken in many such organizations. This work is part of an ongoing research effort aimed at studying spontaneously emerged knowledge preservation mechanisms at IPEN that could be leveraged and may be replicated in other organizations. In a previous paper recently presented at the XXIX Sunbelt Social Networks Conference a first round of results were presented, with emphasis on: (a) measuring the output of the network; (b) characterization of its key global properties and those of its key players; and (d) test of its robustness. This work shows some further results along the same path and starts a new perspective trying to unveil the factors and mechanisms that were responsible for the creation and nurturing of this network.

CNEN in the IRIS Project
2002 - BARROSO, A.C.O.; BAPTISTA FILHO, B.D.; PALMIERI, E.T.; SABUNDJIAN, G.; ANDRADE, D.A.; MACEDO, L.A.
IRIS, the International Reactor Innovative and Secure is an international development program of an innovative, water cooled reactor designed to meet the requirements of proliferation resistance, enhanced safety, cost effectiveness, modular deployment, innovative waste management and high efficiency fuel. By the end of 2001 CNEN signed a collective agreement with Westinghouse Electric Company to officially participate in the development of this integral primary system reactor (IPSR). CNEN team is responsible for the internal pressurizer design and for the independent review of RELAP 5 input file. The design tasks for the pressurizer have included steam-water volume sizing, pressurizer to vessel physical separation, thermal insulation and surge connections dimensioning. Future work will address the need of passive spray devices, honeycomb insulation and surge baffles. This paper present some of the most relevant characteristics of the IRIS design and the preliminary results of pressurizer design, operating modes analysis and transients analysis with RELAP 5.
