Laverdure on vacation

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. Safety

No issues.

2. Schedule

   Near term schedule Media:img_3327.jpg

3. JLAB Internal Group Projects

UIM (Wijeratne, Wright, Creel)

Cold box #3 Linde has returned to begin working through start up and cooldown sequences and move into acceptance testing next week. Double check what support might be needed for the weekend.

GPP (Yang, Thilan)

Kinney Pump Relocation

• Detailed design of Kinney suction and discharge piping system was completed.
• The material for Kinney suction has been received. The material for Kinney discharge has ordered.
• Started the detailed design package of the cooling water system.
• The actual design hours have been over the budget. This is mainly because:

 1. The modification of the existing Coalescers piping system was not initially budgeted.
 2. More efforts were put on the design in order to meet the clearness requirement of the control panel.
 3. The girder and other components near the piping system had to be modeled after interference between the piping and structure components were found.
 4. The design of the piping support was much more than originally estimated.

Gas Management System

• 35% concept planning has been completed.
• The 3D model was done based on the concept design.
• All pneumatic control valves have been ordered.

Check on parts ordering. Valves, transducers, venturies

CHL2 C6 (Perry, Creel)

C6 installation work has started. Mechanics are working now. Electrical work is complete. We are expecting about 2 more weeks of work to complete installation then commissioning will start. Code is loaded. Controls check out started. We will perform main motor bump and magnetic centering Thursday. Still on track for PHPK visit.

JLAB Guard Vac (Schleeper, Radovic)

Electrical techs are completing the power and controls work. Mechanical will then modify the railings.

CHL LN2 Dewar Fill Transfer line (Schleeper)

-process improvements being tested -vacuum needs to be pumped -relief valve needs to be replaced/ordered (will set up a meeting)

JLAB recovery header rework (Saringer, Nate)

Job is being re-planned to shrink the required down time and cost.

JLAB Vaporizer (Perry)

We have most of the parts. The installation is on hold. It might be used as a filler job if things ever get light. Robert will check if there is any instrumentation and controls associated. Not this year.

CHL to FEL Utubes (Perry, Corey)

If a designer becomes available they will be placed on this project. It is currently in Craig's queue.

CHL LN2 Dewar Instrumentation Replacement (Schleeper, Thompson) causing errors in the pressure gauge on fill station.

CHL LN2 Pressure Building Coil leaks (Schleeper, Thompson, Hunewill)

ESR Carbon Replacement (Schleeper, Butler)

Evaluate changing the carbon during the summer shutdown 2018.

ESR Oil Containment (Schleeper, Thompson), working. Paused to support C6 work.

CHL1 Regeneration Skid Removal (Schleeper, Thompson)

4. JLAB External Group Projects

Hall B 12GeV (Thompson)

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 as needed.

Solenoid is expected 12 May ????. Scott says officially its June.

UITF (Perry, Radovic)

Thermosiphon being installed. Utubes are being fabricated. The electrical controls work will start after guard vacuum.

CHL2 Main Compressor Oil Level Alarms (Saringer, Wright)

We are having trouble managing compressor oil levels especially when there are large ambient temperature changes. We need to work on a solution. Drawings are approved. We will start ordering parts soon.

NL cooldown header re-connection (Schleeper, Wright)

-NL piping has been purged with GN2, and pumped/backfilled (20mTorr). cool down flange has been re-connected and relief valve installed. -cool down valve has been tagged to contact creel or dixon prior to use. -long term plan is being developed.

Sintered Metal filter test: -skid has been fabricated. Testing set to begin ????

SRF is planning to replace cold windows on 15 modules

Ongoing.

5. JLAB External Projects

LCLS2 (Dixon)

We are building two recovery compressors. Due in July 17'. (Issac) We are building a guard vac skid for LCLS2. Not started. Due end of October 17'(Issac). We might also fabricate a water skid. FDR for 2K cold box Mar 9. Issac and Stapleton found grit or metal shavings in the inlet piping of the compressor. Bill Crahen is investigating.

We are starting to buy hardware to build 230 bayonets in approximately 6-7 months.

Shop is starting to cut metal for the vacuum skid.

CTF CMTF Junction Box

Repair of EV245RT Coming up with preliminary design for applying force without an EV.

CHL

Inspection of Relief Devices per Pressure System's Requirement: Started CTF and CHL2. Meeting yesterday to decide path forward. Alicia is writing several task hazard analysis, CTList, TOSP.
