Charge The review objectives include...

* Define the location of additional bolts

* Finalize the material selection and design of the shim, load washer, and spherical washer

* Establish the minimum bolt preloads for joints with through bolts and tapped holes

* Establish the adequacy of the bolted joint design through analysis consistent with NCSX Structural and Cryogenic Design Criteria and the NCSX Handbook for Bolted Joint Design (draft attached)

* Document the envisioned assembly sequence and assembly requirements

The review should establish a firm basis for going forward with final design and for performing the tension tests (PPPL) and shear tests (ORNL) to qualify the design of the modular coil interface hardware.
