RP1 (Radiation Protection Level 1) in detail
Radiation Protection Level 1 (RP1) is one of the modules in the Common Nuclear Knowledge (CNK) program. It complements the Savoir Commun du Nucléaire - Niveau 1 (SCN1) training course, because to be able to follow this course, trainees must hold an SCN1 training certificate that is less than 4 years old.
The program is designed to enable operators to acquire the specific knowledge required in the fields of radiation protection.
This scheme complements the regulatory "safety" training adapted to the workstation, and the training in quality assurance rules specific to each company, which is the responsibility of the employer.
The RP1 course, which lasts 4 days for initial training, 2 days for refresher training and 2 days for bridging training, is designed to enable all participants to implement the operator's basic rules on radiation protection.
RP1 training objectives
The aim of this program is to provide category A or B workers exposed to ionizing radiation with the essential notions of radiological risk prevention, so that they can apply best practices when working in a Supervised Zone (ZS) and/or Controlled Zone (ZC) at a Nuclear Power Plant (CNPE).
Target audience
RP1 training is aimed at all personnel who need to work in a Controlled Zone and/or a Supervised Zone on an EDF Basic Nuclear Installation (INB), and who require RP1 clearance.
Level of prior knowledge required
Proficiency in the language of instruction: reading, writing, speaking
SCN1 training certificate less than 4 years old
Animation language
This training is led by one or more trainers who master the language of instruction. However, depending on the organization, it can also be given in several languages.

Course duration
RP1 training lasts 28 hours for the initial course, 14 hours for the refresher course and 14 hours for the gateway course.
NB: For courses held in a language other than French, this duration may be increased by one hour per day.
The companies concerned
Any company working on the industrial installation of a nuclear power plant in a Controlled Zone and/or a Supervised Zone.
Certificates and authorizations issued
On successful completion of the course, the trainee will be issued with an RP1 training certificate. This certificate is a prerequisite for RP1 authorization by the employer.
Certificate validity
The RP1 certificate is valid for 3 years, with a 6-month tolerance. During this period, the employee can work in a Controlled Zone and/or a Supervised Zone on a nuclear power plant.
Once this period has elapsed, the trainee will have to undergo refresher or initial training again, at the employer's discretion.
Teaching objectives - Target skills
At the end of RP1 training, trainees will be able to :
- Acquire a responsible attitude to radiation protection and respect procedures and instructions.
- Identify the specific radiation protection risks and countermeasures specified in a worksite risk analysis.
- Distinguish between radiological hazards and the types of exposure encountered on a nuclear site.
- Explain the ALARA principle and apply the radiological cleanliness approach.
- Apply basic rules concerning radioactive waste and effluents.
- Explain the content and relevance of intervention procedures and the actions to be taken in the event of radiation protection incidents and accidents.
Choosing a training organization for RP1 certification
Key factors to consider
- A CEFRI-certified and EDF-approved training organization
- A CEFRI-certified and EDF-approved RP training site
- Trainers qualified by the training organization in accordance with CEFRI and EDF requirements, with a genuine pedagogical approach and technical expertise.
