JEMA has successfully completed the installation and commissioning of the five power supplies for the superconducting magnets of the JT60-SA nuclear fusion reactor.. The contract was awarded to JEMA through a public tender in 2013 by the French Centre for Nuclear Research (CEA) and included the design, manufacturing, factory testing at 100% of nominal power, transportation, installation and commissioning of five power supplies for superconducting magnets of Idc +20kA / -20kA and 1000V voltage each.

The acceptance of the equipment in Japan is an important milestone for JEMA as it represents the culmination of a technically complex project that was completed within the deadline. Meeting the requirements and deadlines stipulated in such a large-scale project is yet another boost to JEMA's position in the field of nuclear fusion.

The site acceptance test (SAT) was successfully completed last July following 100% compliance with the required specifications of CEA and the European agency for nuclear fusion F4E. JEMA conducted equipment testing at full power in its own facilities, which provides great value for the customer. Because of this capacity, JEMA has been able to accelerate the work on the ground in Japan for the commissioning of the equipment, and has received the express recognition of the customer for this achievement..

The JT60-SA fusion reactor will be one of the largest in the world and will be commissioned in 2019. The magnetic configuration of the plasma, which will have an approximate power of 240MW during the pulse, will be supplied entirely by JEMA power supplies. The supply of the other eight power supplies required for the reactor's superconducting magnets was also awarded to JEMA through another international tender, by the Italian Energy Agency (ENEA).

The installation and commissioning of the five power supplies required compliance with the customer's numerous specific requirements for their integration in a large and complex installation. The JT60-SA project in Japan now joins JEMA's extensive list of references in this field.. There is also increasing interest in nuclear fusion within the private sector and several private organizations are currently entrusting JEMA with the development of their power supplies. JEMA has extensive experience in the field of nuclear fusion. At the start of the 90s it was already supplying all the systems for the TJ-II machine of Madrid. The advances developed in this field in recent years have reinforced JEMA's international position - today it is recognized as one of the most qualified suppliers of power conversion systems in the world. JEMA has references of magnet power supplies and high voltage power supplies (RF heating and NBI) in many well-known fusion machines, both public and private, such as Joint European Torus project JET (United Kingdom), Tri Alpha Energy (United States), TCV-CRPP (Switzerland), Wendelstein 7-X IPP (Germany) IPR (India) and MAST-U or Tokamak Energy (United Kingdom)

JEMA wins the tender for the installation and commissioning of the eight magnet power supplies for JT60-SA in Japan

 

The contract, awarded by Fusion for Energy (F4E), is a continuation of the recently completed installation and commissioning of five power supplies by Jema for JT60-SA.

The eight power supplies were previously manufactured and tested by JEMA under another contract with the Italian Energy Agency (ENEA) in 2013. The installation and commissioning of these eight power supplies begun in September 2017 and completion is scheduled for the first quarter of 2019. JT60-SA will become one of the largest fusion reactors in the world.

The thirteen power supplies required for the magnetic plasma confinement are built by Jema and can deliver approximately 240MW of pulse power.
