05/02/2017 Meeting

Attendance

Thompson, Creel, ,Radovic, Dixon, Wright, Butler, Radovic, Wijeratne, Norton, Saringer, Schleeper, Yang, Perry, Laverdure

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

We had an incident where an individual was working in the SBR compressor room and tripped over installed piping and injured his leg. His injury required stitches and is a recordable event.

2. Schedule

3. Operations (A brief description of the highlights for the past week at CHL's, ESR, HDR, CTF)

CTF is operating. Team is working on reassembling the K2.

ESR normal.

CHL1 at 4K

CHL2 is off to support C6 work.

CHL Recovery: Purifier 5 carbon has been replaced. pump and backfills on-going. After purifier 5 is online and operating acceptably, carbon will be replaced in bed #4.

HDR Normal

4. JLAB Internal Group Projects

CHL1 SC1 CC5

Final utubes for disconnecting SC1 are to be done Wed and Thur.

Air Liquide is expecting to have technician here on site first or second week of May.

Decisions need to be made regarding the flanging/sealing of the CC.

UIM (Wijeratne, Wright, Creel)

Calendar

The shutdown is scheduled from 17 Feb - 9 Apr (Dewar Full). We are in clean up mode anticipating restart around Thursday.. Anticipate problems with the controls during the cooldown.

GPP (Yang, Wright)

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. Paul is working on the detailed drawings. Some are ready for review. Valves have been ordered for Kinney suction lines.

Kelly contacted the HAWKINS-HAMILTON for potential liquid ring pump replacement. The vendor proposed the NASH 2BE4 32 vacuum pump. We can adjust our current laytout for this potential replacement. But it seems that our inlet pressure is far out of the pump performance curve. Shirley is going to check with the vendor - UPDATE: NASH AT3006 with a minimum inlet pressure of 1 in Hg abs was recommended by vendor.

Reviewed the 35% concept plan for the gas management. Thilan is working on the regulator valve for the recovery mass-out valve. Need to know if the main compressor bypass valve can be sized for only running the two compressors at the same time.

Gas management tie-ins were finished.

35% of gas management concept plan was reviewed on Mar. 2, 2017. Several issues were discussed:

1. The maximum air pressure for both Fisher and Badger control valve regulators were confirmed. 2. Robert / Jonathan and Mat are going to look options for new pressure transducers for the new gas management skid. The local tabs are required. 3. Robert is going to look how to run tubing and conduit. 4. Need to determine (Thilan, Mat and Shirley?)if the flow meter needs to be installed on the skid. 5. Thilan is going to check the cooling water header to make sure it is sized properly.

CHL2 C6 (Perry, Creel)

C6 installation work has started. Mechanics are working now. Electrical should finish by the end of the week. We are expecting about 4 more weeks of work to complete installation then commissioning will start.

JLAB Guard Vac (Schleeper, Radovic)

-Legs are being cut and prepped for anchor/grout. DONE! -Taps need to be added to the pump suction. (fab) IP -remove/route the conduit (Electrical) -remove railing (ops) -Instrument Air line (fab) -final assembly of pump/filters (ops) -controls (electrical)

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 3rd Recovery Compressor (Saringer)

The skid is complete. We are purchasing a pneumatic actuator to install on one of the existing compressor suction valves to see if it prevents oil migration problems.

JLAB recovery header rework (Saringer, Wright)

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

JLAB Vaporizer (Perry, Wright)

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.

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 Fill Relief Replacement (Schleeper, Thompson) Replacing existing relief valve. Evaluate fill process to prevent lifting the relief.

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)

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

CHL1 Regeneration Skid Removal (Schleeper, Thompson)
