DRAFT MUST BE MODIFIED AT MEETING
Attendance
Thompson, Creel, Dixon, Wright, Laverdure, Butler, Radovic, Wijernatne,
Goals
The purpose of this weekly meeting is to discuss plant operations and group projects with the cryogenics group managers and supervisors. During this meeting we will discuss ongoing and future projects, priorities, manpower, schedules, expenditures, and problems.
Agenda and Notes
1. Operations
CMTF is having problems with the LCLS2 cryomodule testing. They have had issues with reaching the desired pressure.
CHL C7 and C8 have their suction check valves installed sideways. People are going to call the manufacturer and make plans to turn them upright.
2. Projects
A new utube is being fabricated with a manual valve to replace the existing utube because it has a leak. Drawings are released but have not been delivered to Scott to see and order parts.
The pre-shutdown work was scheduled to be finished by Christmas but it will spill over into January for about 1 week. The manufacturer has shipped the reworked venturies and they should arrive soon. (Dano, Troy, Fuentes, Conlin).
We are currently working on a new plan that splits the installation and commissioning/testing of CB3.
Venturies are on site but not with Scott yet. Scott will find them and Thilan verify them against the drawings. At the current time we believe we will be starting the shutdown on Feb 17. Jonathan is working with FM to plan to move the 480V electrical junction box above the new cold box.Thilan is working on the TOSP's for pressure testing. Buddy and I are working on a plan to install the junction box #4.
Designers are working on the drawings for moving the Kinney pumps. Shirley has approved the current conceptual design for the suction piping. Designer is also working on the cooling water header designs. The drawings are finished for the small warm gas tie ins that we will try to install during the Feb shutdown.
The mechanical material has arrived. As soon as a crew becomes free they will start fabricating the piping spools. (Likely Willy)
We must order the electrical supplies including 4160v wire, 120v/480v conduit and wire.
We must find out the status of the funding from Rusty.
The electrical materials were ordered today. Piping spools are being fabricated now.
Pressure tests completed. Vacuum, leaks sealed. CM should be in place in 2 weeks to allow the final utube measurements to be taken. Then it will take about 4-5 weeks to build the utubes. We have the parts.(Roy)
The thermosiphon can fabrication and installation is expected to take about 2 months to build and install. Likely to be Dano's crew once they complete UIM.
HDIce return line is a fill work. Its low priority.
Tech is working on the LN2 subcoooler liquid level probe. Fab is working on the thermosiphon. The height of the can is sufficient.
We have been tasked with fabricating flex lines for the solenoid can. It will take approximately 4 months. (Jay)
Roland is continuing to work with Ruben on solenoid can instrumentation.
We are working to accumulate the pressure systems documentation.
We are looking for an in house designer to replace the contractor Michael. The scope of the work is not clear.
All but 2 bayonets were shipped. The remaining 2 had to wait for the original valve we spec'ed to arrive. The SLAC group overrode our valve selection at design time and opted for a cheaper valve that does not meet pressure requirements.
We are building two recovery compressors. Due in July 17'. These will take more hours than estimated because of seismic modifications. (Issac)
We are building a guard vac skid for LCLS2. Not started. Due end of October 17'(Issac)
SLAC operations is interested in drafting a long term support agreement for after the machine is running. (??)
Cold compressor FDR was completed last week (results unknown). PHPK is continuing to fabricate the first set of warm compressors.
The guard vac skid is mechanically installed. The electrical power and controls need to be finished. There is one more box to install. We are waiting for wire to be delivered to complete the job.
The electrical installation is 66.469% complete. The water tower pressures are compatible with the skid.
On hold.The skid is mechanically finished. The skid is electrically 50% finished. There is no funding or plan to install the machine yet.
We have most of the parts. The installation is on hold.
Started building flex lines. It will take 1-2 months. Roland is finishing the I&C installation which much be done by end of Jan.
CHL to FEL Utubes
If a designer becomes available they will be placed on this project.
The Kinney suction piping modifications are in engineering and design. The piping will be inside the building. We plan to buy supplies and fabricate by the end of FY17'
The gas management system modifications are in planning. This will require a shutdown to install.
Action Items
1. Kelly will ping Rusty about funding for the electrical supplies for JLAB C6 installation.
2. Jonathan, Mat, and Thilan will complete the modifications to the CTF CB3 installation plan and try to get an answer on the Feb 17 shutdown.
3. Add other group engineers to this meeting.
Action Item Updates
1. As of 01/04/2017 Kelly reported that Rusty says to move forward with purchasing the electrical hardware for the CHL2 C6 installation.
I gave Buddy the go ahead to buy the parts.
2. Perform EI&C maintenance on CHL2 while it is down for 6 weeks this summer.
3. Perform EI&C maintenance on CHL1 while it is down for several months this summer.
