- Angra 1 NPP in-service inspection and in-service testing programs for operating license and long-term operation Ana Rosa Baliza Youssef Morghi Amir Zacarias Mesquita Biología in ASME Code Angra 1 NPP License Renewal service inspection The in-service inspection program of the Angra 1 plant is updated every 10 years, according to applicable standards - designer (American Westinghouse project based on NRC requirements) and CNEN. NRC approves the use of ASME Section XI (In-service Inspection of Nuclear Power Plant Components). To provide this assurance for those components that are subject to the requirements of the ASME Boiler and Pressure Vessel Code presents as requirements a set of rules has been formulated to provide assurance that the functional requirements of the components are available when required. The rules have been arranged to provide appropriate levels of assurance according to the importance of the component in its relationship to plant safety. The classifications that are established during design and manufacturing have been adopted to provide the levels of importance for the components. Nuclear power plants (NPP) have operation license for 40 years. Angra 1 operation license will complete 40 years in 2024. But, according to international standard an NPP can renewal the license for more 20 years. Brazilian standard does not have requirements for license renewal. So, CNEN had prepared two technical notes for License Renewal and Long-term operation for NPP in Brazil - CNEN NTCGRC-007/18 and NT-CGRC-008/18. Angra 1 had already started the Renewal License and Long-term Operation project and ISI program will need to be on the Aging Management Program form, that require more robust trend analyzes, corrective and preventive actions and others attributes. The main purpose of this article is to show the ASME section XI subsections that are important for the License Renewal and Long-term Operation for Angra 1. 2020 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280924010 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3A Vol.8
