| 1.#2 Method(1) * Take a sensitivity by an operator. * 4 people stand by (MCE, IFI, PRM), (PR3, PR2, BS), (SR2, SR3), (SRM OMC) FFU switchs. * Turn off almost FFUs at the same time by 4 people, except for pink one. * Take the sensitivity again before alignment will change. * Check the difference btw FFU operation and almost no FFU operation. <<BR>> |

Plans for trial just after ER
- Noise investigation about FFUs in the corner stations by an operator.
- Preparation
Make marks on FFU switches that are not turned off in MCE, IFI, PRM, PR3, PR2, BS, SR2, SR3, SRM, OMC with "Pink Tape".
(Operated FFU / Total FFU) table list is below.
130 FFUs will be turned off. This corresponds to 26kW heating power.
26kW corresponds to about two water cooler cooling power (2 x 14kW).

- Preparation
- Method(1)
- Take a sensitivity by an operator.
- 4 people stand by (MCE, IFI, PRM), (PR3, PR2, BS), (SR2, SR3), (SRM OMC) FFU switchs.
- Turn off almost FFUs at the same time by 4 people, except for pink one.
- Take the sensitivity again before alignment will change.
Check the difference btw FFU operation and almost no FFU operation.
