Action Items for HAPL MI Chamber Core

• Schematic of overall configuration to be used
  as basis for studies (C. Priniski)
• Compare tritium removal from flibe and from
  Pb-17Li (C. Gentile)
• Containment concepts to minimize size and
  shielding (C. Gentile)
• Include all ancillary rooms/vaults in layout
  (HTS, Tritium, Pumping, Target Injection) (C.
  Gentile/check with M. Sawan on shielding
  requirements)
• Formalize vacuum pumping system through laser
  ports (C. Gentile)
• Minimize coil weight and cost (possibility of
  using Rutherford configuration (F. Dahlgren)
• Temporal and spatial ion energy distribution on
  dumps (B. Robson)
• Dump design including armor configuration and
  maintenance (R. Raffray/G. Sviatoslavsky)
• HX material size (R. Raffray/ G.
  Sviatoslavsky)
• Blanket attachment and maintenance scheme with
  smaller opening for both main blanket region and
  upper/lower blanket regions (C. Priniski/G.
  Sviatoslavsky)
• Beam shielding, support and attachment outside
  biological shield (G. Sviatoslavsky/M. Sawan)
• Thickness of blanket for VV to be reweldable
  (M. Sawan)
• How to maintain tight fit between adjacent
  blanket modules.use of compliant layer
  (Graphfoyl??) (PPPL)
• Failure mode effect analysis - check TFTR
  experience, others? (C Gentile/R. Raffray)
• Assessment of blanket fabrication properties
  (SiC/SiC) (L. Snead/ G. Sviatoslavsky)
• How to join SiC/SiC piping during blanket
  replacement (mechanical joint i.e flangebolts
  probably preferable to welding or other
  processes)? (L. Snead)
• How to drain different blanket sections (G.
  Sviatoslavsky)
• Set up conference call within about a month to
  discuss progress on these action items (R.
  Raffray)
