ITER NEWSLINE 8
In addition to the Design Office, the CEPS Department has responsibility for the pellet injector, the steady state electrical power network, the coil power supplies, the hot cell and radwaste services integration, the radwaste treatment and storage, the radiation monitoring, the vacuum systems, the tritium plant, the cooling water systems, and the cryogenics systems and distribution. So in many ways, the CEPS Department represents the life blood of the ITER project.
This year, the ITER Design Review is the highest priority. The list of actions resulting from the Review are used to generate a series of work plans, which detail what actions and resources are needed to finish the specifications of the Procurement Packages in time. Staffing and resource requests are then based on these estimates.
The input from the group working on the tritium plant issues (one of the eight Design Review working groups) has been given a more permanent character by the formation of a new Tritium Plant Project Team, including one member of each Participant Team, which will help steer the activities of the Tritium Plant Section and commit resources needed to generate detailed design packages in the tritium plant area. A similar team was formed by the Cryogenics Section.
The other sections in our Department are filling up quickly and starting their operation, on which we will report in a separate article on a later date.
In anticipation of the start of ITER operation, the Centre National de Recherche Scientifique (CNRS), Université de Provence and CEA are jointly launching a series of "ITER Physics Summer Schools". Their main goal is to offer advanced graduate students and recent PhDs a complete picture of both the theoretical and experimental aspects of tokamak physics.
The first Summer School will take place on July 16-20, 2007 at Aix-en-Provence, in parallel with the Fusion Theory Festival which is organized every odd year, and is devoted to the problems of turbulent transport in magnetic fusion devices. The emphasis of the first School will be on the physics of turbulent transport and its implications on confinement.
During the meeting held on Tuesday 20 February, representatives of the Autorité de Sûreté Nucléaire (ASN) and the Institut de Radioprotection et de Sûreté Nucléaire (IRSN, a support team of ASN), paid a visit to the ITER site to see the progress of the site preparation (see picture).
"Inside the ITER Organization as well as in the Domestic Agencies, many people will be involved with ITER for the first time. Therefore we need to broaden the knowledge base. And the best way to do so is to involve people in solving problems under the guidance of people who already know the details of the ITER design."

The ITER machine will contain ten such cryo-pumps that produce the vacuum necessary to operate the torus and the cryostat. The ITER torus pumps are unique in that they must function in a fast cyclic mode continuously pumping and regenerating the exhaust of the burning plasma, including the helium produced as a result of fusion.
The pump will take 18 months to build and will undergo a period of intensive testing at the TIMO-2 pump test facility at Forschungszentrum Karlsruhe. This prototype pump will enable validation of the design and fabrication methods prior to procuring the main batch of ten pumps for ITER.
ITER Director-General Nominee, Kaname Ikeda, comments: "I attach great importance to the International School and believe a critical issue in attracting high-calibre personnel to ITER is that we ensure their children receive a good education. Therefore, I welcome this important step, and I am counting on the full support of the Region for the further development of the school."
Introducing ... Dhiraj Bora, DDG Designate CODAC & IT, Heating and Current Drive, and Diagnostics (CHD) Department
For almost 25 years since then he has been active in plasma physics research, most recently at the Institute for Plasma Research (IPR) in Gandhinagar. Dr. Bora´s primary interest has been radio frequency heating and current drive in tokamaks. He has been the project leader of the RF group in his institute since its inception. In the past fifteen years the group has developed heating and current drive systems based on high power commercial tubes at megawatt levels and different frequencies. In his earlier days, Dr. Bora was involved in measurements using microwave diagnostics and bolometers in tokamak plasmas.
At ITER, he is responsible for diagnostics, CODAC, heating and current drive systems. He will have to make sure "that the plasma within the ITER device behaves the way we want it to," he said.
