Definition of a PDR
NCSX
PDR (pe’de-ar) n. 1. A project-level DOE review to
determine if the maturity of the project’s design and
cost and schedule estimates is adequate to establish
the performance baseline. 2. A subsystem-level
internal review to determine if all the deliverables for
Preliminary Design have been satisfactorily
completed.
The June PDR will be both a project-level DOE review
and a subsystem-level internal review of the Vacuum
Vessel (WBS 12) and the Modular Coils (WBS 14)

Requirements for the project
level DOE review
We need to establish the Preliminary Design Baseline
• Update the design of the stellarator core to reflect
configuration changes since the CDR and incorporate the
new modular coil design and vacuum vessel design
• Update the design of ancillary systems consistent with the
updated stellarator core design
• Update all cost and schedule estimates
We need to document the Preliminary Design Baseline
• Write a Preliminary Design Report (similar to CDR)
• Provide backup documentation for cost and schedule
estimates

Requirements for an internal PDR
NCSX
Performance requirements have been defined
A design has been developed that fully meets those requirements
All feasibility issues have been resolved
Interfaces with other systems have been fully defined
Plans for assembly, installation, and test are established
Models and drawings have been developed, reviewed, and
released at the Preliminary Design level
Activities needed to address PDR requirements for the VV and
modular coils should be identified in the SEMLs

Other key milestones
NCSX
again, representative dates

Summary
NCSX
We have a coil design!
The PDR has slipped until the week of 23 Jun because of
the delayed arrival and to put some time between the
PDR and the QPS CDR (26 Apr)
The PDR will serve two purposes – DOE’s requirements
for establishing the performance baseline and our own
requirements for proceeding with the Final Design of
the VV (WBS 12)and Modular Coils (WBS 14)
