Abstract
Paying attention to diversification of Brazilian energy matrix and the approach of the decommissioning of nuclear power plants in Brazil and around the world, such as Angra I nuclear power plant, planned for 2025, this paper presents a study of repowering and staggered decommissioning of a PWR (Pressurized Water Reactor) nuclear power plant from a combination of gas turbine and nuclear power plant. The proposed combined cycle “gas-nuclear”, as reported in the literature, operates a gas turbine cycle connected with a nuclear power plant steam cycle (secondary loop) using a Heat Recovery Steam Generator (HRSG). After extending the life of a nuclear power plant the nuclear thermal power is gradually replaced by adding gas turbines, and then the nuclear reactor is shutdown. Energy and Exergy analysis about the combined cycle “gas - nuclear” and a standard NPP were made to compare the behavior of the arrangement. The Engineering Equation Solver (EES®) software was used for the simulations where different coupling were tested seeking the best operating conditions.
