  2. Overview • A0’s flow requirements • Flexible scenario that accommodates for HX cleaning; redundancy • Scenarios simulated: • Scenario A: 2 pumps at E4 and 2 pumps at F1 • Scenario B: 2 pumps at F1 and 2 at F2 • Scenario results • Reconfiguration of F1 and F2 service buildings to have 2 pumps • Conclusion

  3. A0’s flow requirements finalized • Spoke to John Reid about A0’s flow requirements • John stated that the current flows are higher than what is actually necessary • John also said that the 4” LCW header at A0 would need a minimum of 60 GPM @ 75 Psig • One of the major loads: 3.9 GHz Klystron, that needs 25 GPM of flow, most probably will be moved to NML • Also, the heat load at A0 is very small: 24 kW

  4. Flexible scenario that accommodates for HX cleaning Service building 1 Service building 2 Pump 1: On Pump 2: Off Pump 1: On Pump 2: Off Normal operation Service building 1 Service building 2 Pump 1: Off Pump 2: Off Pump 1: On Pump 2: On Service building 1’s HX being cleaned Service building 1 Service building 2 Service building 2’s HX being cleaned Pump 1: On Pump 2: On Pump 1: Off Pump 2: Off

  5. Scenarios simulated:Scenario A:2 pumps at E4 and 2 pumps at F1 • All the flow rate requirements of the loads leading up to F4 enclosure were satisfied, however, if 2 pumps were being operated at E4 while F1’s HX was being cleaned, the following flows were predicted at F4 and A0:

  6. Scenarios simulated:Scenario B: 2 pumps at F1 and 2 pumps at F2 • All the flow rate requirements of the loads leading up to F4 enclosure were satisfied, and F4 and A0 flows are as below: Normal operation, one pump at F1 and one at F2

  7. Scenarios simulated:Scenario B: 2 pumps at F1 and 2 pumps at F2 F1 service building’s HX being cleaned, 2 pumps running at F2:

  8. Scenarios simulated:Scenario B: 2 pumps at F1 and 2 pumps at F2 F2 service building’s HX being cleaned, 2 pumps running at F1:

  9. Reconfiguration of F1 and F2 service buildings to have 2 pumps • Unfortunately, F1 and F2 service buildings have only one pump per building: Continued..

  11. Reconfiguration of F1 and F2 service buildings to have 2 pumps • In order to get a fairly good estimate of installing another pump, I am currently working with SEA contractor Jose Rangel • Jose said: • All the connecting piping would be stainless steel and not aluminum • To install one pump, and re-pipe the headers such that two pumps would run in parallel, it would require: • Two contractors working full time • Total number of 6” welds= 20-25

  12. Reconfiguration of F1 and F2 service buildings to have 2 pumps • The completed service building would look something like: Continued..

  13. Reconfiguration of F1 and F2 service buildings to have 2 pumps

  14. Reconfiguration of F1 and F2 service buildings to have 2 pumps • Importance of redundancy: • According to Paul Czarapata, redundancy is not as important as it was during Tevatron’s Run II • However, it is desirable because the following experiments would be expecting beam: • The neutrino program • 2 test beams at Meson • Special projects • It costs close to $60,000/hr to run the accelerator complex, and if there is no redundancy the accelerator complex would have to be down for 3-4 days • Thus, a comparatively small investment to accommodate redundancy would prove to be fruitful from an operations perspective

  15. Conclusions • Using E4 service building would not provide sufficient flow to all the loads in the MR remnant • Having 2 pumps at F1 and F2 would work for us • Redundancy is not as important as it was, but its still desirable • Future plans: • There is talk about using the A and B Tevatron sectors for a Plasma Accelerator project • There is also talk about IARC (Illinois Accelerator Research Center) using Tevatron’s cooling system water • If these plans get approval, then Scenario B (2 pumps at F1 and F2) will not work
