20 positions at the CSN 2026: requirements, deadlines and how to apply

Key data

The Nuclear Safety Council opens 20 high-level positions in its Senior Scale for the 2026 fiscal year. The call, published on 27 October 2026, is based on the Public Employment Offer 2026 approved through Royal Decree 387/2026 and establishes two differentiated access routes: open competition and internal promotion.

For those working in the nuclear, energy or regulatory bodies sectors, these positions represent one of the few stable incorporation routes to a first-level technical body with competencies in nuclear safety and radiological protection in Spain.

What does this call establish?

The resolution convenes a selective process to fill 20 positions in the Senior Scale of the Nuclear Safety and Radiological Protection Corps, with scale code A1300, classified in group A1 of the General State Administration.

The positions are distributed in two access systems:

The valid university qualifications for access through the open competition system are:

• Doctor
• Licentiate
• Engineer
• Architect
• Graduate (university degree qualification)

The application for participation is exclusively electronic, using form 790 through the General Access Point of the Administration. Notifications of the process will also be made by electronic means, through the Citizen Folder.

Economic and operational impact

For applicants, joining the Senior Scale of the CSN means accessing a group A1 position in a specialized regulatory body. Group A1 positions in the General State Administration entail basic remuneration and supplements specific to the highest level of the civil service system.

For organizations in the nuclear and energy sector, the opening of these positions has relevant operational implications:

• The CSN strengthens its technical capacity with 20 new high-level personnel, which may influence the pace of processing authorizations, inspections and regulatory resolutions.
• Companies in the nuclear sector that regularly interact with the CSN can expect greater response capacity from the body in the medium term.
• Civil servants of subgroup A2 of the CSN itself or other bodies have a direct route for promotion to group A1 through the 3 internal promotion positions.

From the perspective of HR planning in the public sector, this call is part of the Public Employment Offer 2026 approved by Royal Decree 387/2026, which confirms the body's intention to consolidate staffing in the current fiscal year.

Who does it affect?

• Higher education graduates (Doctor, Licentiate, Engineer, Architect or Graduate) who wish to access the CSN through the open competition route.
• Persons with disability equal to or greater than 33% with higher university qualification, who have a specifically reserved position.
• Career civil servants of subgroup A2 with at least two years of seniority who aspire to promote to group A1 through the 3 internal promotion positions.
• Companies and entities in the nuclear sector that operate under CSN supervision and will see the technical capacity of the regulatory body strengthened.
• Advisors and consultants specialized in civil service and energy sector who advise candidates or organizations on HR planning.

Practical example

An industrial engineer with five years of experience in a nuclear sector company who wishes to make the leap to the public sector can apply through the open competition route. His Engineer qualification is expressly included among the valid qualifications. He must complete form 790 electronically through the General Access Point and activate his Citizen Folder to receive all notifications of the process, as they will not be sent by postal mail.

On the other hand, a civil servant of the CSN or another AGE body classified in subgroup A2 who has been active for more than two years can apply for one of the 3 internal promotion positions, which would allow him to advance to group A1 without competing with the entire group of external applicants.

What should interested parties do now?

1. Verify that you meet the qualification requirements: only qualifications of Doctor, Licentiate, Engineer, Architect or Graduate are valid. Check that your degree fits before starting the process.
2. Activate the Citizen Folder: all notifications of the selective process are made exclusively by electronic means. If you do not have your Citizen Folder active, do so as soon as possible so you do not miss any official communication.
3. Prepare form 790: the application for participation is processed obligatorily electronically through the General Access Point of the Administration using this specific form.
4. If you are an A2 civil servant, evaluate the internal promotion route: check if you have at least two years of seniority as a career civil servant in subgroup A2. If so, you can apply for the 3 positions reserved for internal promotion, with significantly less competition.
5. Consult the complete call in the BOE: review the full text published on 27 October 2026 in the BOE (BOE-A-2026-22478) to learn about the syllabus, scoring system and exact deadlines for submitting applications.
