A qualitative approach of the regulation for the life extension of brazilian nuclear power plants

Abstract

The advantages of Long-Term Operation (LTO) in dealing with the end-of-life-cycle issue of Nuclear Power Plants (NPPs) in operation today, when compared to the creation of new NPPs, have major social and economic implications. The Life Extension process of the Brazilian NPP Angra 1 has already started, and its methodology is well defined in the technical notes NT-CGRC-007/18, (CNEN, 2018a) [1] and NT-CGRC-08/18, (CNEN, 2018b) [2]. This work aims to present a critical analysis of the two technical notes. The technical notes are in an initial version, therefore, the results of their verifications and validations are presented, which were carried out through a qualitative analysis, the factors that can be modified to be adjusted and/or modified to generate improvements for the notes or documents that may replace them.
