Tokamak Cooling Water System, team members continue with preliminary design activities including collaboration on using the international computer-aided design. The team is working closely with representatives from the IO Cooling Water Section and In-vessel Component Division to establish draining and drying parameters. Currently the team is initiating integrated draining experiments by developing a plan for testing physical properties and hydraulic performance at the water/gas interface. The first procurement of TCWS equipment is underway with the Drain Tank Final Design Review and evaluation of proposals to fabricate from five drain tanks manufacturers. US ITER is reviewing and commenting on the second revision of Process and Instrumentation Diagrams for distribution to the ITER-IO.

For
Diagnostic Systems, first procurement arrangements are awaiting input from high level discussions regarding commissioning and operation of US ITER diagnostics. The diagnostics team is on track for the completion of Annex B of the Procurement Arrangement for the low-field-side reflectometer this fall.

In
Vacuum, Pumping and Fueling Systems, a Procurement Arrangement (PA) for the Vacuum Auxiliary System was signed in April. Team members have improved the modeling technique for the cryogenic viscous compressor (CVC) roughing pump design. CVC swirl tube testing is underway now. A pellet shattering system for plasma current disruption mitigation will be tested in July.

Tokamak Exhaust Processing System, staff continue essential preliminary design activities and are coordinating with the IO to resolve changes to the TEP Task Agreement for 2011. Changes to the work plans will be made once apath forward is finalized.

The
Steady State Electrical Network team is engaged in discussions with the EU/F4E about possible changes in US scope responsibilities; alternate proposals are now under review. A new procurement arrangement draft will be ready this summer.

The
Ion Cyclotron Transmission Lines System team continues with R&D and preliminary design activities. A design contract for gascooled coaxial transmission line componentswas awarded in May. The team also issued a RFP for prototype high-current and high-voltage tuning capacitors. In addition, a prototype was designed to evaluate the "guided radar" method of arc detection for use inside ICH transmission lines.

In the
Electron Cyclotron Transmission Lines System, contracts were awarded for short-pulse and long-pulse power test loads. The staff also received IO approval of the US Quality Plan for the EC transmission lines procurement arrangement. To support preliminary design progress, the USIPO and MIT have hosted visits from the ITER officer responsible for EC transmission lines.

US ITER has awarded 90 major contracts totaling over $103 million. Significant awards include $25.9 million to Luvata Waterbury and $7.7 million to Oxford Instruments for superconducting strand for the toroidal field (TF) conductor; $19 million to AREVA Federal Services for design and engineering support for the tokamak cooling water systems; $5 million to MIT for scientific/engineering support of the magnet and electron cyclotron systems; and $4.1 million to High Performance Magnetics (formerly known as CICEFT) for integration services for the TF conductor.
