8 pack meeting notes – November 6th, 2001

 

Agenda:

1.     Baseline Configuration - Leif Eriksson

2.     Configuration Management - Dennis Atkinson

3.     Klystron water chiller update - Javier Sevilla

4.     Baseline Schedule - Scott Anderson

 Notes:

  1. Baseline Configuration Presentation (.ppt) - Leif Eriksson
    1. 8 Pack conceptual designs are beginning to be put under configuration control. 
    2. The following conceptual designs have been “frozen”, which means they can’t changed without review by 8 Pack management and any effected systems.

                                                              i.      Modulator Power Supply Location

                                                            ii.      Modulator Wishbone Design being done LLNL

                                                          iii.      Raised floor around racks and modulator.

    1. Still Open Issues

                                                              i.      Secondary Containment for Modulator oil.  3 options are being assessed.

                                                            ii.      Vacuum electronics and cabling configuration.  Being evaluated.

  1. Configuration Management Presentation (.ppt) – Dennis Atkinson
    1.  Interface Control Document  template is a form that was used at NIF and will be used the 8 Pack project.
    2. The interface Matrix shows the identified interfaces.  There are 30 ICDs to be written for 60 interfaces. Interfaces are counted twice in matrix.
    3. Dennis will send out the ICDs to every identified group and he will contact all the groups to get the information written down into ICDs. 
    4. There is no formal configuration software in place at the moment, but it is being initiated.
  2. Chiller Requirements revisited – Javier Sevilla
    1. Three chiller options and their costs:

                                                              i.      Air cooled chiller inside ESB is cheapest

                                                            ii.      Air cooled outside ESB  + $12500

                                                          iii.      Water cooled inside ESB  + $5494

    1. Costs do not include spare.  Question:  Should a spare chiller be purchased? 
    2. Question: Can the chiller type used at CID be used for 8 Pack?  Answer:  The specification for 8 Pack chiller requires a much higher pressure than the CID chillers put out.  Would need to add a booster pump.  See Action item 1
    3. Question:  Do we need a chiller for cooling the klystron magnets?  Answer:  That is the current specification, but the first XP3 has not been run so there is no data back up the modeling which set the specification.  Thermal data should be available in January.  Question: can we wait until January to order the chiller?  See Action Item 2
  1. Baseline Schedule Presentation (.ppt) – Scott Anderson
    1. Presentation shows some of the schedule objectives.  Most dates shown in presentation are ending dates, except for the test dates.  Full schedule is available on the 8-Pack web.

 

Action Items:

  1. See if using a CID type chiller and booster pump is cost effective and see if there are spares for the CID chiller.  – Javier Sevilla
  2. What is the latest date that the chiller can be ordered and arrive in time to be installed for running the 4 – Pack?  - Javier Sevilla
  3. What is the schedule for determining the earthquake specifications for the modulator, klystrons and the racks?  - Leif Eriksson
