Subject: NBI Upgrade Weekly Status 4/22/11
Al,
NBI
Upgrade: A NBI technical Peer Review was held this week to assess
progress toward the FDR in June. This review covered work since the PDR last
June. COGs reported that design work and drawings are done or near done.
Analysis on the armor confirms survival for operational scenarios for stresses
and temperatures. Some additional design details will be included for hot
spots. Some additional work continues based on global model analysis for
reinforcing the vacuum vessel. The VV modification prototype setup and testing has
started. This work is on track for completion prior to the FDR.
NBI
Refurbishment: Setup and core drilling of the old full energy ion dump
continued in situ this week. These samples will be tested for residual tritium.
Additional machining on the full energy ion dump continued in the shop.
Regards,
Tim
