COMPLETED

Upcoming Issues

• In July 2015 we will need to power the entire site (except the village) off of Kautz Road SubStation (KRSS) for a year while operating– A new Master SubStation (MSS) will be built

beside the old one– We have the capacity, but don’t know if we can

run a Physics Program• Possible noise on the lines• Expect some problems with the Proton

Source• Planned on starting up from the shutdown

with the site on KRSS to test• Gives us some time to address problems

– We don’t know what impact it may have on the rest of the Lab

• Will lights flicker?• Will processes be sensitive to the Main

Injector ramp?

When do we test?

– Met with FESS and AD Departments to discuss possible test dates and impacts to schedules

– Set up a meeting for tomorrow with Division/Section power representatives to confirm test date

– Lock in a test starting date (proposed date is November 4th)

– The duration of the test will depend on the results

• If we can operate, stay on KRSS for some time to allow the Lab to cycle through its normal power usage. Look for an agreeable time to switch back.

• If we cannot operate, switch back to using both substations after a few days, apply fixes, regroup, retest

– Working with FESS HV to put together a likely schedule for the rolling power outages across the lab while the power feeds are being configured
