Entry  Monday, February 11, 2019, 10:26, Isaac Earle, Safe Module Parking, Development, , , SMP shield box and vacuum vessel moved to Target Hall 6x

  On February 8th the SMP shield box (IRH1675) and the vacuum vessel (IRH1806) were both raised from a horizontal to vertical orientation in the ISAC-1 Experimental Hall.  Hamilton "Mini-Mite" S-MM2-43FS caster wheels were then installed on the base of the shield box and it was lowered down the hatch to the B2 level.  The vacuum vessel was then lowered into the shield box, supported by the rollers, as designed.  The shield box and vessel combination were then moved south along the steel plated floor until positioned under the hatch leading to the Target Hall.  Movement along the floor was achieved by pushing the back of the vessel with an electric fork truck and pulling from the front with a cable winch attached to a plate mounted in the floor in the SHC service area, centered east/west between the Ante Room doors.  The fork truck alone was sufficient to move the assembly on the smooth section of the plates, but the winch was needed on the section paitned with textured grit.  The vacuum vessel was then lifted into the Target Hall and placed in a temporary storage location in the silo area.  The shield box was then lifted, casters removed, and then lifted up into the Target Hall.  It was a very tight fit with the tubing which has been installed on the SHC and NHC ducting for the new flow meters, but the move was completed without causing damage.  The shield box was placed on the B2 level in the Target Hall where some final tapped holes will be added on the exterior before moving to the final installation location.

 

 

Entry  Thursday, January 31, 2019, 14:16, Isaac Earle, North Hot-Cell, Development, , , NHC grounding approval NHC_grounding.pdf

 Franco Mammarella was consulted regarding electrical grounding of the NHC design (RS103 of Document-131915).  After discussing the design, and having grounding inspected by Randy Boehm, Franco approved the design and advised that the grounding system should be inspected periodically.  This task has been added to the Remote Handling inspection index on an annual schedule.  A PDF copy of the e-mail correspondence with Franco is attached.

3 damaged 24VDC plugs of TP solenoid valves are replaced. Inspected other plugs. All of them are in good condition now.

Entry  Tuesday, January 22, 2019, 09:56, David Wang, ITW, Maintenance, TM2, , ITW water system maintenance. 

ITW water system maintenance is done. All working paddle wheels and coils are replaced. ITW water system polyurethane tubes are replaced as well. Two 3/8" leak small valves on return lines are replaced. 85 liters of tritium water are transferred from storage tank to B2 level holding tank. LALC water are refilled into S-tank. Restarted pump and checked system. Everything works fine now. No water leak has been found so far.

Entry  Friday, January 18, 2019, 10:26, Isaac Earle, North Hot-Cell, Development, , , NHC sealing improvements and repeat of RH test for LED lights 

The following NHC development work was completed under WP I2019-01-09-4:

  • Location of RH feature on operator level LED lighting updated to match IRH1800 Rev B design
  • Remote Handling test of the LED fixtures was repeated using a 9' pole with hook attachment through the manipulator slave hatch from the Target Hall: both LED fixtures were removed and reinstalled successfully with relative ease
  • Tool port seal replaced to address an audible air leak: the 1/4" foam seal was removed and replaced with adhesive backed 5/8" wide hollow foam rubber seal (McMaster Carr PN: 93085K81). Prior to the change DPG4 was at 0.63"wc, after the change wit was 0.73"wc with all system variables constant.
  • NHC manipulator access block seal was replaced, likewise to address an audible air leak: the 1/4" foam seal was removed and replaced with adhesive backed 1/2" thick BunA-N rubber strip (McMaster Carr PN: 9023K85).  DPG4 was at 0.94"wc prior to the change, and 1.07"wc after with all system variables constant

No issue.

Entry  Friday, January 11, 2019, 13:59, Isaac Earle, Safe Module Parking, Development, , , SMP motor selection decision 

SMP drivetrain design work is currently underway.  Alejandro has selected a suitable 1200:1 reducer which will give a vessel rotation speed of 0.21rpm with a 1725rpm motor (deemed sufficiently close to the SHC rotation speed of 0.17rpm).  The reducer however is only rated for 0.33hp, and Allon's analysis recommended we use a motor of at least 0.4hp

 
From his calculations the expected power required to turn the loaded vessel is 0.2hp (see Document-161943, p3).  The higher figure of 0.4hp in his final recommendations comes from the power rating of a 40 tooth sprocket (the driver sprocket) with a No. 50 roller chain operating at 10rpm (the lowest speed shown on the table) - meaning this driver sprocket arrangement can handle up to 0.4hp.  We discussed this on the phone on January 4th and agreed that a 1/3hp motor could be used which will match the reducer Alejandro selected, and will supply sufficient power given that calculations indicate only 0.2hp is required.
 
Once the vessel is installed in the shield box a test will be performed to determine the actual torque (and power) required to turn the vessel.  If the value differs significantly from the calculated value the design will be revisited.

 The spent target in the south hot cell has been moved to the spent target vault. It was placed in pail 204 and placed in spot 6B. The pail is made of thicker steel and thus will not need to be repackaged later.  The ISAC spent target vault is full there is no more room for any more targets.
