8. Previous Review Recommendations – FDR 3/17
Provide the following documentation to the SLAC Building Inspection Office for review and approval prior to releasing an RFP:
1. Vacuum vessel (79222-P0002) seismic analysis and anchor scheme (79222-A0001.
2. Formalized analyzes of the internal piping for seismic, thermal and shipping requirements.
3. 2D drawings.
A project level decision was made to advance the procurement process before the completion of the typical review cycle.
These documents are complete and underwent an internal review process prior to the RFP.

9. Previous Review Recommendations – FDR 3/17
Have a procurement specification written, reviewed and approved by the project prior to the procurement readiness review.
Complete.
Justify loss of redundant isolation valve downstream of the last CC for the high flow (1st Light) case.
Complete. In both cases there are two isolation valves in series.
Produce a reviewed and signed off assembly sequence document.
The assembly drawing structure defines a sequential and detailed fabrication sequence. This will be thoroughly reviewed with fabricator and optimized where appropriate.
Evaluate and verify access to components on the 2K cold box with the u-tubes installed.
Access to components was evaluated and assured in the design.

10. Previous Review Recommendations – EPR 1/18
JLab shall document the process required to reconfigure the 2K Cold Box internal piping to accommodate low flow operation.
Complete. Part of Mechanical Design Presentation.
* - It should be noted that the current design is only for the high flow configuration. Additional engineering, design, & fabrication steps are required for any potential future conversion to low flow.
JLab will evaluate increasing the valve/line size within 2K cold box to accommodate off-normal condition of 4K return flow
Complete. Implemented change of PV41212 and associated piping to 2”.
JLab will revise piping analysis to document design philosophy.
Complete. Addressed in Piping Flexibility Analysis Presentation.
JLab will perform benchtop test of 2K heater.
In process. Addressed in Testing / Commissioning Presentation.
