Last signature for ITER Russia

With the signature in April of a final Complementary Diagnostic Procurement Arrangement with the ITER Organization, the Russian Domestic Agency has now formalized the procurement of its complete in-kind scope—two dozen work packages in all that define the equipment for ITER that is under Russian responsibility.

Holding up the plastic model of what will soon turn into a 10-ton diagnostic tool: Tokamak Engineering Department Head Alexander Alekseev, Russian Domestic Agency Head Anatoli Krasilnikov, Port Plugs & Diagnostics Integration Division Head Mike Walsh, ITER Deputy Director-General Eisuke Tada, Procurement Responsible Officer William de Cat, Diagnostic Engineer Natalia Casal, and Mikhail Kochergin from the Ioffe Institute in St. Petersburg.

Holding up the plastic model of what will soon turn into a 10-ton diagnostic tool: Tokamak Engineering Department Head Alexander Alekseev, Russian Domestic Agency Head Anatoli Krasilnikov, Port Plugs & Diagnostics Integration Division Head Mike Walsh, ITER Deputy Director-General Eisuke Tada, Procurement Responsible Officer William de Cat, Diagnostic Engineer Natalia Casal, and Mikhail Kochergin from the Ioffe Institute in St. Petersburg.
The Complementary Diagnostic Procurement Arrangement signed on 14 April by Anatoly Krasilnikov, the head of the Russian Domestic Agency, and Eisuke Tada, ITER Deputy Director-General, covers the fabrication and delivery of the diagnostic equipment that will be integrated into lower port #8. This includes the required structures and services for the integration, installation and operation of three diagnostics: the erosion monitor, divertor Thomson scattering, and laser induced fluorescence.

The function of these structures is to accurately position and align the diagnostic systems in the ITER machine and to provide structural integrity to withstand the harsh conditions inside of the vacuum vessel at maximum machine performance. Last but not least, they will provide neutron shielding to guarantee that radiation doses are kept below the established limits in areas where human access is required.

The diagnostic equipment will be installed inside of a support structure called a diagnostic rack, a stainless steel structure measuring 4 metres and weighing 10 tons. It will be fully remote handling compatible and connected to the main services such as cooling, gas and electrical supplies. Other equipment covered in the Complementary Diagnostic Procurement Arrangement are ex-vessel structures such as interspace and port cell support structures.

With this final signature, all Russian contributions to the project are now in the hands of industry.
