Technical instructions are technical nuclear safety and radiation protection standards that become binding once they have been published in the Boletín Oficial del Estado, Spain’s official journal.

Legally speaking, technical instructions are permanent regulations. They become part of Spanish legislation and, like any general legislation, they are subject to judicial review. Infringement of technical instructions is an administrative offence.
 
The process the Nuclear Safety Council (CSN) follows to draft instructions encourages participation by stakeholders and the public. In addition, before technical instructions are approved by the CSN, they are reported to the Congress of Deputies and even to the European Union,  in case they concern radiation protection.
