Attendance
Thompson, Creel, ,Radovic, Dixon, Wright, Butler, Radovic, Wijeratne, Norton, Saringer, Schleeper, Yang, Perry, Carlton, 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
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.
CHL1 T2 tripped off once.
Hall "C" has been sending high flow back to the recovery compressors causing the reliefs to lift at ESR.
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
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.
4. JLAB Internal Group Projects
UIM (Wijeratne, Wright, Creel)
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 warming. Warm tie ins are underway. Cold tie ins will be started after plant is warmed. Controls team is working on cold box #1 and expander #1 conversion.
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 modified.
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.
EECO made a mistake on the MV cable. They are working to correct the situation.
Carr Electric is coming to install the conduit and wiring this week.
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.
JLAB 3rd Recovery Compressor (Saringer, Creel)
On hold. The skid is mechanically finished. The skid is electrically 99% finished and Beizer is working on 480V electrical connections now and should be done this week. There is no funding or plan to install the machine yet. 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.
ESR Hall A 15K utube (Schleeper)
Complete and will be installed when required.
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)
We are moving forward with the installation of a PC and overhead projection monitor in the small conference room. The projector has been installed and is ready to accept a PC. Buddy 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. Torus was recooled and is ready for KPP run.
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.
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.
6. JLAB External Projects
MSU (Dixon)
We are working to accumulate the pressure systems documentation. The scope of the work is not clear. Cory and Kelly are coordinating what additional work might move to MSU from JLAB. JLAB might be picking up cryomodule design work and possible magnet work.
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.
