","Stevenson","Smaller cuts in the vessel were evaluated prior to arriving at the present design solution. The increased tangency radii are necessary for current drive and higher performance which are key goals of the upgrade. The increased tangency radii, the NBI fan array, and the TF outer leg at Bay K require a change to the Bay K opening because the beam trajectory cuts across the interstitial wall of the vacuum vessel between Bay K and Bay J. Because of the removal of the metal in the area to allow beam passage a cap was added to move the vacuum boundary out and to carry the stresses in this region. Rather than lose Bay J for diagnostics, the port was added to the cap also. These issues drove the size of the cap and the size of the VV hole. ","Closed.","CLOSED",null,"YES","Verified with Tim Stevenson on 9/30/10.  A more modest modification of the proposed large cutout of the vacuum vessel was considered.  It was determined that a smaller cutout is not feasible as the larger cutoff is needed to meet the requirements in the NSTX Second Neutral Beam General Requirements Document (Revision 0, 4/1/09).  The GRD requires the second NBI to be installed in such a way that the 3 beams are tangent to the radii: 130 cm, 120 cm, and 109.4 cm.

The new design utilizes Superbolts which will eliminate the concern that a clamping load is achieved without creating a torsional spring from the bolt.  Superbolts are designed to achieve the specified load, their jack bolts are also pre-lubricated to allow the proper load to be more easily set.  Details on the Superbolts are outlined in slide 23 of Tom Willard's  \"TF Flex Joint and Stub Bundle\" presentation from the June 23-24, 2010 PDR. ","Jedic","Willard","August 2009 Peer Review"]
