[en] The purpose of this Annex is to report lessons learnt from the resumption of Angra 2 NPP construction and to analyze them with a view to resumption of Angra 3 NPP project. Angra 2 is in operation since February 2001, and Angra 3 is close to resumption. In 1976, at the beginning of the Project, a twelve-month time gap between the conclusion of the two plants was planned. Later this time gap was changed to 18 and then to 24 months until the investments were greatly reduced in the period from 1984 to 1994. A programme for equipment storage and preservation was implemented and inspections were planned. Personnel were maintained to continue with the engineering work and site structures. Construction was resumed only for Angra 2 with full cooperation of the foreign supplier. Many challenges had to be overcome before Angra 2 could be successfully concluded; the core loading took place in April, 2000, the operational commissioning phase followed and was concluded in December, 2000. Therefore, Angra 2 Project was in development for 25 years. At the time Angra 2 was concluded, the utility tried to start the construction of the third unit, but the Authorities did not allow it, claiming funding problems and requiring additional studies to demonstrate the economic feasibility of the project. These studies were developed and approved and the Angra 3 project resumption decision is expected to be made in the next months. (author)
