Conceptual Design Requirements for FIRE
John A. Schmidt
FIRE PVR
March 31, 2004
Outline
• Conceptual Design Requirements• History• Issues to be addressed during Conceptual
Design• Conclusions
Requirements for Conceptual Design
• The two sources of requirements for completion of conceptual design are:
– The DOE Critical Decision process
– Engineering requirement to initiate Preliminary Design

Mission Need Review (CD-0)
• Key review elements for a Mission Need Review are:– Mission Need Statement. Assess adequacy of documentation
confirming that the new project provides a specific capability that the Department currently lacks to meet its assigned mission.
– Program/Mission Requirements. Assess whether high-level requirements are sufficiently defined to identify potential alternatives (to be analyzed in the next phase) that are both applicable and capable of meeting project goals.
– Total Project Cost and Schedule Ranges. Review basis of the rough order of magnitude cost range and provide an assessment of whether this range reasonably bounds the cost and schedule of alternatives to be analyzed in the next project phase. Review basis of schedule range and assess whether the schedule is consistent with strategic requirements for when this project is required. Also, for projects closely linked to other projects, assess whether schedule results in appropriate integration.
CD-1 Documentation
• Conceptual Design Report - Alternative Analysis, Hazard Analysis, Site Selection Criteria, NEPA Documentation, Systems Requirements, cost and schedule estimates
• Risk Management Assessment
• Safety Documentation
• Acquisition strategy
Requirements to Initiate Preliminary Design
• Subsystem Requirements
• Feasibility– Is there a design solution within the allotted
envelopes?
• Cost (range)
• Schedule
Sliding Joint
PF Coils
OH Coil
Vacuum Vessel
TF Coil Inner Leg Assembly
TF Coil and Case
Dewar
Conceptual Design Issues - Magnets
• Solenoid leads
• Elbrodur fatigue
• Welding R&D
• Insulation R&D
Conceptual Design Issues - PFC’s
• Time dependent forces
• With transient thermal
• Connected to the vessel
• Startup with passive plates
• Magnetic detectors with passive plates
• First wall cooling for AT operation
Conceptual Design Analysis - VV
• Plastic analysis
• Limit analysis
• Optimized geometry and refined FEA models
• Dynamic analysis
• Fatigue analysis, including plastic effects
• Seismic analysis
Conceptual Design - VV
– Develop design of generic port plug
– Optimize divertor attachments for
stress, remote handling
– Design internal plumbing and
shielding
– Re-design / optimize gravity supports
Conceptual Design R&D - VV
– Select/verify method for bonding of copper cladding to vessel skin
– Select/verify method for routing of cooling passages into and out of cladding
– Develop fabrication technique for in-wall active control coils
– Perform thermal and structural tests of prototype vessel wall, with cladding, tubes, tiles, etc. (need test facility)
– Verify assembly welding of octants and tooling for remote disassembly/reassembly (need test facility)
Remote Maintenance Conceptual Design
• Many in-vessel remote handling system designs and procedures remain to be developed in concert with components– Divertor module remote attachment and handling interface– FW tile and limiter module attachment, handling end-effector and
interface– Standardized midplane port assemblies and handling systems– Upper and lower auxiliary port assemblies and handling systems– In-vessel inspection (metrology & viewing) system deployed via
midplane port
• Ex-vessel and hot cell remote handling systems have less design development– Component transfer casks, transport and positioning at ports (crane vs
air cushion, how are casks positioned at upper auxiliary ports?)– Upper and lower vertical ports are currently being fitted with diagnostics
but can they be maintained?– Hot cell layouts, remote handling systems and component repair stations
Conclusions
• The FIRE design is well positioned to complete the engineering required for Conceptual Design.
• The biggest effort will be in Remote Maintenance - both design and initiating R&D.
• It should be relatively straight forward to complete Conceptual Design in about nine months given approval of CD-0 and adequate funding.
