Economic evaluation of a mobile nuclear power plant using uranium over 5% enrichment. <b>Light Water Reactor Fuel Enrichment beyond the Five Per Cent Limit: Perspectives and Challenges</b>.

Disponível em: http://repositorio.ipen.br/handle/123456789/31921.http://repositorio.ipen.br/handle/123456789/31921Moble nuclear power plants seem to be an interesting alternative to provide electric energy to isolated regions because the conventional electric network cannot reach isolated cities, islands, offshore and merchant ships. These reactors would be built over a floating barge that could go to client’s place. This new concept brings up new maintenance and operation issues, especially about autonomy and availability. This study evaluates economic advantages and limitations of using over 5% enrichment fuel on a mobile nuclear power plant (NPP). A supposed mobile NPP is taken as an example and used as calculation basis. An enrichment over 5% could better adjust the maintenance event periods, improving the plant availability, reducing operation costs and improving the competitiveness of this plant type. In addition to the high costs of the enrichment process, the fuel burnup limits and the maintenance activities restrict high levels of fuel enrichment. Therefore, this work suggests a fuel enrichment condition capable to conciliate both cost and performance for a supposed mobile NPP.openAccessavailabilityburnupcostcostenrichmentmaintenancenuclear fuelsnuclear power plantsoperationuraniumCapítulo de livro0000-0002-6689-3011https://orcid.org/0000-0002-6689-3011
