Artigo IPEN-doc 31154 Soft Systems Methodology as an approach to the safety management of nuclear facilities2024 - GUILHEN, S.N.; CAMARGO, I.M.C.; POTIENS JUNIOR, A.J.; MARUMO, J.T.; SILVA, T.M. da; RUBIN, G.A.; VIEIRA NETO, A.S.This manuscript presents an account of the Sociotechnical Systems Safety Analysis Group’s (GASSST) application of Soft Systems Methodology (SSM) to a complex safety issue at the Nuclear and Energy Research Institute in São Paulo, Brazil (IPEN-CNEN/SP). Drawing from both theoretical foundations, based on the documentation produced by Peter Checkland and other researchers, and practical experiences, the study explores the SSM approach in addressing challenges that involved technical and human factors.The principal results include the identification of key stakeholder perspectives, the development of a rich picture to capture the complexity of the problem, and the initiation of potential solutions. However, the full application of SSM was curtailed due to proactive interventions by the facility staff, which resolved the initial problem before all SSM steps could be completed. The process was further interrupted by the COVID-19pandemic-induced hiatus, during which facility staff were absent for 1 year and 10 months.The study concludes that timely application of SSM and the expertise of facilitators are critical for navigating complex safety issues effectively. This experience underscores the need for experienced practitioners and a more prompt application of SSM to fully leverage its potential in addressing organizational challenges. GASSST's reflections anddocumented experiences contribute valuable insights to the ongoing discourse on SSM's practical relevance in similar contexts.Artigo IPEN-doc 30521 Soft Systems Methodology (SSM) as an approach to the safety management of nuclear facilities2024 - GUILHEN, S.N.; CAMARGO, I.M.C.; MARUMO, J.T.; SILVA, T.M. da; RUBIN, G.A.; NETO, A.S.V.Relatório IPEN-doc 28911 Revisão do Questionário Técnico do Reator IPEN/MB-01 (BRH / Dezembro 2021)2022 - BITELLI, ULYSSES d'U.; RUBIN, GERSON A.Esta Informação Técnica tem por finalidade registrar a revisão 8 (Agosto/2022) do Questionário Técnico do Reator IPEN/MB-01, visando o atendimento às exigências do Parecer Técnico nº PT-COSAP/CC-011/2022, rev. 0, de 05/08/2022, constante do Processo SEI nº 01341.004248/2019-60.

This approach, however, doesn’t properly address the complex dynamic interactions between technical, human and organizational factors occurring within and outside the organization. After the accident at Fukushima Daiichi nuclear power plant in March 2011, experts of the International Atomic Energy Agency (IAEA) recommended a systemic approach as a complementary perspective to nuclear safety. The aim of this paper is to present an overview of the systems thinking approach and its potential use for structuring sociotechnical problems involved in the safety of nuclear installations, highlighting the methodologies related to the soft systems thinking, in particular the Soft Systems Methodology (SSM). The implementation of a systemic approach may thus result in a more holistic picture of the system by the complex dynamic interactions between technical, human and organizational factors.Publicação IPEN-doc 01416 Equacoes de estado para a agua leve1982 - RUBIN, G.A.; GRANZIERA, M.R.Artigo IPEN-doc 06742 Modificacao do sistema de protecao do reator IEA-R1m para operacao a 5MW1999 - RUBIN, G.A.; MONTEIRO, P.R.B.; MASOTTI, P.H.F.Artigo IPEN-doc 06923 Safety of research reactors: sensors and actuators fault detection and isolation in nuclear research reactors2000 - GONCALVES, I.M.P.; PENHA, R.M.L.; RUBIN, G.A.Artigo IPEN-doc 03482 SIMPCO - Uma ferramenta para estudo de sistemas de controle de centrais nucleares1996 - RUBIN, G.A.; SOARES, A.J.
