Subject: NBI Upgrade Weekly Status 2/18/11
Mike,
NBI
Upgrade: For the vacuum vessel modification, evaluation of the weld
design for the Bay K cap continues. The global model shows stresses between Bay
K and L that require attention. Design details are being considered to
ameliorate stresses in this area. This item is the last main area to be
resolved in preparation for the Peer Review. At the BL2 meeting this week, this
weld item, the armor, and the bellows were discussed and appear to be in good
shape. The existing duct was checked for clarification of details to be incorporated
in drawings. A significant amount of designer time is yet required for NBI to
prepare for the FDR in June. No refurbishment activities were planned this week
due to outage tasks taking near term precedence.
Regards,
Tim
