ITER Converter Preliminary Design Reviewed

count: [2012-07-30] [Close]

A meeting was held on July 16-18 in Beijing to review the preliminary design (PD) on ITER Converter Procurement Package (PA). Chaired by Dr Alberto Coletti, ENEA, attended by CN/DA, KO/DA and ASIPP engineers, the meeting reviewed the PD from the perspectives of feasibility, reliability, maintainability,economy and environmental protection.

The review panel comprised Professor Pan Huanhong, CN/DA, representatives from ITER organization, Professor Charles Neumeyer, PPPL, Professor Wang Jing, Ohio State University, Dr Tang Guangfu, China Electric Power Research Institute.

Deputy Luo Delong, Director of CN/DA, delivered a welcome speech and a brief introduction on the content, scope, objective and task progress of converter PA. Dr Ivone Benfatto, ITER IO power supply division responsible officer (RO) and and Dr Dong Ling, CN converter procurement package RO introduced the design contents, important milestones, design difficulties and progress made in China.

After listening to 15 reports on design principal, design schemes and time schedules, the review panel and DA representatives had deep discussion, and exchange ideas frankly, they concluded that this ITER PA preliminary design meets the technical standards with reasonable specifications, accurate setting of parameters, excellent design structure system.  The review panel gave 54 comments on ITER converter PA design, much less than the average number, usually more than 100, of comments given on other preliminary designs. ASIPP staff will improve the preliminary design according to the comments of review.

The converter PA, undertaken by ASIPP, is the biggest CN ITER PA and the first functional PA for preliminary design review. ASIPP scientists complete the preliminary design with high quality within 6 months after December 2012 when contract was signed.

Background: Converter power system is one of the important subsystems of ITER Tokamak device. The system receives AC from 66KV busbar of impulsive power network, and delivers controllable DC current/voltage to superconductor coil. It provides necessary engineering fundamental and control for the generation, control, maintenance, heating of plasma, and the control over the current, position, shape, distribution and breakdown of plasma. This power system is a vital factor for the performance and security of ITER device, and determines whether the physics experiments will succeed or not.
