The commitment of the Empresa Nacional de Residuos Radiactivos, S.A., S.M.E., (Enresa) for accessibility.

The website of the Empresa Nacional de Residuos Radiactivos, S.A., S.M.E., (Enresa) has been built with the aim of facilitating universal access to all people who consult it regardless of their physical, sensory or intellectual abilities, and the technical context. of use with which they do it (type of device, software, connection speed, environmental conditions, etc.).

Therefore, we work with the objective of eliminating the barriers that hinder access to information and communication.

The commitment of the Empresa Nacional de Residuos Radiactivos, S.A., S.M.E., (Enresa) is to achieve the “Double-A” (AA) level of conformity, as required of public administrations by European and state legislation.

The Directive (EU) 2016/2102 of the European Parliament and of the Council of October 26, 2016 establishes the standards required of Member States so that all public sector websites and mobile applications, regardless of the device used to access them, meet the accessibility requirements set out in the standard UNE-EN 301549:2022, accessibility requirements for public procurement of ICT products and services in Europe.

The standard UNE-EN 301549:2022 is mainly based on the Web Content Accessibility Guidelines (WCAG) 2.1, from August 2018. Specifically, it is necessary to meet level AA. However, the standard also has other additional, mandatory and conditional requirements.

The directive is mandatory, but it is not directly applicable, which is why at the state level a royal decree has been developed that develops the scope and requirements, at a minimum. The state transposition is Real Decreto 1112/2018, of September 7, on accessibility of websites and applications for mobile devices in the public sector.
