Work Continues


Cryo Operations

  • Tevatron at LN2 temperature and LN2 usage is stable with vendor deliveries running only 2-3 truckloads per day due to the Tevatron being 1/4 at room temperature. Helium losses are slightly up at 18 kscf/day (1/2 of normal during TeV operations); some of the loss was replenished with A0 GHe Recovery from the test caves.
  • A1 and A3 are at room temperature and isolated with LOTO.
  • D1 and F4 are also at room temperature, have been reconnected by Cryo, and are under helium flow. D1 is ready for Division sign-off.
  • F4 cooldown will wait until TEL-1 is re-installed.
  • B4 and E2 were cooled down to LN2 temperature.
  • A3 has been completed by MSD, but spool piece conning towers will be retrofitted (5 out of 8 leak) by Tech Division during this shutdown. Cryo has completed epoxy of helium leaks on Tevatron power lead and snoop leak tested fine.
  • Pbar D60 Debuncher tanks have been reconnected to system and we are awaiting Division sign-off before cooling down to LN2 temperature.
  • ACNET application programs relating to FRIG operations continue to be tested on Linux consoles.
  • Nitrogen Reliquefier startup is delayed due to concern of “old” electrical cables being used for cross-connect between MSS and KRSS, especially due to high startup currents of 3000 hp TSI compressor.
  • MCR monitoring cryo operations

CHL Maintenance:

  • General facility maintenance is in progress, including testing of relief valves per FESHM.
  • CHL Helium Compr “A” cooling tower installation has been completed with only some minor work is left, such as fencing; system testing will be commencing.
  • CHL Helium Compr “D” is being overhauled.
  • Helium Coldbox-2 controls upgrade is in progress.
  • Mobile Helium Purifier is being derimed at room temperature and piping modified.

FRIG Maintenance:

  • Various FRIG bldg vacuum maintenance and instrumentation repairs (e.g. lost charge on VPTs) are in progress, as well as support work on houses at room temperature and other equipment as things fail even during the shutdown period.
  • Various Mycom compressor maintenance: leak hunting and general repairs, F0#3 motor starter replacement in progress.
  • Wet expanders overhauls have been completed for A1 through F4; one D-Zero Dry Expander was also completed with modifications. AP30 and CDF remain to be done.
  • Kautzky relief valves have been replaced from C1 through F4 (16/24). Pace is at one house per day though running into problems with galling nuts on clamp's T-bolts and bad compression fittings. More Clamp T-bolts are on order.
  • We have been finding some leaking quick-disconnect fittings on conning towers. We have none in stock and thus ordered units expected next week.

Facility Engineering Services

  • Zebra mussel cleaning, though waiting for approval, is scheduled to begin on May 8 and continue for a minimum of 16 days.
  • Proposed Treatment
    • EVAC Introduction Stage
    • Flushing Stage
