Autor: María C. Romero-Toribio, Elena Angulo, Ramón C. Soriguer, Javier Madrigal, Francisco Senra-Rivero, Xim Cerdá, Joaquín Cobos
Publikováno v: Land, Vol 13, Iss 10, p 1706 (2024)
Prescribed burns have recently become a widespread environmental management practice for biodiversity restoration to reduce fuel load, to provide forest fire suppression operational opportunities, to favor plant recruitment or to manage wild species.

New insight studies of the secondary phase formation under repository conditions
Autor: Joaquín Cobos, Laura J. Bonales, Nieves Rodríguez-Villagra
Publikováno v: MRS Advances. 5:539-547
In a deep geological repository (DGR) scenario, uranium oxidized in aqueous systems will be stabilized as UO22+ (hexavalent uranium), as a consequence of tetravalent uranium oxidation by radiolytic byproducts. Uranyl cationic species (UO22+) in diffe

Publikováno v: New Journal of Chemistry. 43:15714-15722
Acetohydroxamic acid (AHA) has been widely used in the development of reprocessing processes for spent nuclear fuel (SNF) due to its ability to form hydrophilic complexes preferentially with tetravalent metals and to contribute to the control of thei

Current necessities of nuclear power plants have led to increase burn-up of the fuel during operation. In this context, some undesirable processes, such as a higher release of gaseous fission products, may occur. New UO2-based fuels are being develop
