The ISTP/IRUP Nuclear Cluster (Pôle Nucléaire®) has been working with companies of the nuclear sector for over 20 years in fields as varied as maintenance, dismantling, construction, and services, either on nuclear power plants and fuel cycle facilities.
This long experience has enabled us to develop a wide range of apprenticeship programs.
Our programs train skilled workers, advanced technicians, and engineers. Our technicians receive training in construction site management, mechanics, control-command, non-destructive testing, valve operation and can access intermediary management positions such as general foreman, integrated service supervisor, and radiation protection manager.
Our commitments in terms of quality assurance and sustainable development, as well as our ISO 9001, CEFRI-F, and CIN (EDF) certifications, testify for our dedication to customer satisfaction and innovation. Companies—whether they are large corporations or SMEs, are involved both in training design for their employees’ continuing education—and in the definition of certification criteria for the degrees awarded by IRUP and Saint-Etienne Graduate School of Engineering.
This constitutes the trademark of lifelong learning programs at the ISTP/IRUP Nuclear Cluster. Our collaboration with and commitment to companies also translate into tangible support actions. Our engineers work together with companies to improve quality, safety, efficiency, and productivity.
The ISTP/IRUP Nuclear Cluster trains students at two different centers equipped with two training worksites and many workshops. We have 75,350 sq ft dedicated to training including 13,000 sq ft of workshops (welding, valves, robotics, operational excellence, etc.).
In 2013, the ISTP/IRUP Nuclear Cluster was awarded the Yves Chellet Prize for its commitment to nuclear education and training. The Master’s of Engineering in Nuclear Facilities Engineering was awarded the Nuclear Training Award for on-the-job training and many other of our programs were nominated in the “apprenticeship” category. In 2014, a student from IRUP and in 2015, a student from ISTP, were awarded the Fem’Energia prize from EDF, WIN France and WIN Europe for their training paths in the nuclear field.
The ISTP/IRUP Nuclear Cluster is a member of French networks IFARE, COPSAR, SFEN, and WIN (Women in Nuclear); it is a partner of many competitiveness clusters such as Viaméca and PNB (Burgundy Nuclear Industry Cluster), and a member of ENEN (European Nuclear Education Network) and I2EN.
Our professional preparation to nuclear professions program trains job-seekers who wish to undergo retraining and turn to the nuclear industry. It is a preparatory qualifying program.
Accreditations: SCN1 (Common nuclear knowledge – level 1), RP1 (radiation protection – level 1) and CSQ (safety and quality).
Our maintenance and nuclear logistics technician program trains young high school graduates in one year to become technicians in maintenance, civil engineering, logistics, and dismantling. It is a qualifying program.
Accreditations: SCN1, RP1, CSQ, crane operator and electrician certifications.
Our maintenance technician specialized in nuclear sites program offers 3 specializations: valves, electrical mechanics, and pipes.
It trains young high school graduates in two years to become operations supervisor. The program leads to a vocational certificate.
Accreditations: SCN 1 and 2, RP1 and 2, CSQ, ARI (Self-Contained Breathing Apparatus), crane operator, electrician, and occupational first-aid certifications.
Our maintenance supervisor in nuclear environment program offers 2 career paths: general engineering or civil engineering. It trains in one year Associate’s degree holders for team supervision and to coordinate maintenance, dismantling, and decommissioning works. They can also aim at technical assistant positions. The program leads to a vocational certificate.
Accreditations: SCN1 and 2, RP1 and 2, CSQ, HN3 (nuclear accreditation level 3), and ARI.
Our operations supervisor in nuclear environment program offers 2 career paths: general engineering or civil engineering. It trains in one year Associate’s degree holders to become chemistry technicians, account officers, or intervention specialists. The program leads to a vocational certificate.
Our Master’s of Engineering in nuclear facilities engineering is jointly run by Saint-Etienne Graduate School of Engineering and INSTN. It can be taken either as a three-year program for future engineers or as 26-month continuing education program. It leads to a Master’s of Engineering degree delivered by Saint-Etienne Graduate School of Engineering.
Accreditations: SCN1, RP1, CSQ.
