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 this week. We have performed

2. Schedule

• Near term schedule Media:img_3163.jpg

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

CTF Shutdown continued. See the section below for UIM.

ESR T2 tripped off twice.

Hall "C" has been sending high flow back to the recovery compressors causing the reliefs to lift at ESR. Ended on Thursday.

Recovery compressors seem to have trouble holding on to their oil. Investigating either using a different check valve or adding an actuator to the butterfly valve. Mat wants to install actuators on the inlet valves.

ESR - Hall C Target cool down complete. KPP on-going.

CTF K2 motor ready to reinstall.

CHL Purifier high DP after the LN2 boiler. After the purifier was cleaned up and put on line, just like the other purifier, there is now a high DP somewhere between the outlet of the LN2 boiler and the return side of the HX. Also, the relief on the on-line purifier seems to be lifting at 230 psig vs its set point of 265psig. We are making plans to remove the relief and send it out to have it rebuilt/calibrated.

Things that need looking at.

CHL2 LHe Dewar liquid level readback is noisy

CHL1 MCB and SC1 vacuum system refurb and add readbacks

4. JLAB Internal Group Projects

UIM (Wijeratne, Wright, Creel)

Calendar

The shutdown is scheduled from 17 Feb - 9 Apr (Dewar Full). A job briefing was completed on 2/14/17. A presentation for the P&C Group underlined the importance of not reassigning people once the down has started. Preparations for the shutdown including lowering CTF LL have been started.

Shutdown is underway. Plant is warm. Warm tie ins are complete. Cold tie ins are underway. Controls team is working on cold box #1 and expander #1 conversion.

Finishing last required cold tie in (D5 tie-in) and working on CB3 LN2 line (outside of shutdown scope). Scheduling pressure test soon.

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)

Its looking probable the accelerator will shutdown 22 March. If it does the C6 work will move up if not the shutdown is planned for first week in May. A fab crew is building the piping spools. for helium, water, and oil (Willy). The electrical supplies including 4160v wire, 120v/480v conduit and wire were ordered and should be on site. The on-skid conduits and wire can be installed as well as the 4160V run from the motor to the starter. The 120V and 480V home runs cannot be installed before the shutdown because the panels are energize. We are getting a price from Paul Powers for the FM contract electricians to perform this work. Perry is working up a plan for the CHL2 shutdown. Chris will have a meeting to discuss the schedule and maintaining cleanliness as much as possible. Chris to write and coordinate approvals for commissioning plans, installation, clean-up, and pressure tests.

Medium voltage cable is here.

We are back to ground zero trying to choose and electrical contractor to pre-install the conduit and wire on the C6 compressor.

JLAB Guard Vac (Schleeper, Radovic)

The guard vac skid is mechanically installed. The electrical power and controls need to be finished. There is 480V and control conduit, wire, gauge panel and tubing to be installed. Roland has assembled and mounted the gauge panel. Solenoids for for inlet valves located and tested. The FM electricians have finished 480V conduit runs and pulled wire (as of 2/10/17). Mechanical need to add an air line run.

Gauge panel was assembled and mounted. Craig is working on the design for an instrument air extension to operate the valves.

Modifications are being planned for this installation.

JLAB 3rd Recovery Compressor (Saringer, Creel)

On hold. The skid is mechanically finished. The skid is electrically 99% finished. We need to verify the installation of the check valve on this compressor. We are missing one pressure gauge.

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.

Bldg 89 Conf Rm B Computer (Evans, Carlton, Creel) Erik is looking for a PC now.

5. 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 at end of March or beginning of April.

UITF (Perry, Radovic)

CM is in place but uncertain when final alignment will occur 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 drawings are ready, 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. Fab is working on the thermosiphon. LN2 supply line is being worked right now. Control system has a couple of weeks of work left to do as soon as a tech becomes available. Chris will check with all parties and determine the real schedule.

Quarter CM is being installed. Fab is waiting on parts for thermosiphon.

Thermosiphon and utubes are being fabricated. The electrical controls work will start after the UIM is finished.

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.

NL cooldown header re-connection (Schleeper, Wright)

Part of the line is not connected and needs to be re-connected. Dave is working on a plan.

SRF is planning to replace cold windows on 13 modules

6. JLAB External Projects

MSU (Dixon)

We are working to accumulate the pressure systems documentation. Plan is to complete this work by next Friday.

Robert is still working 2K controls.

LCLS2 (Dixon)

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. We might also fabricate a water skid. FDR for 2K cold box Mar 9.

LCLS2 is indicating we could pick and choose a host of items we could build for them such as 230 bayonets in approximately 6-7 months.
