Hi Phil,

We plan to conduct the hydrostatic pressure test of MOLLER TM4 today. We will need about 15-20 gallons to fill our magnet. Can we connect our magnet with LCW and fill our magnet with LCW between 9:30 AM and 3:30 PM today? If not, when can we do it?

Many thanks

Eric

Subject: Fill MOLLER TM4 with LCW for Hydrostatic Pressure Test

Hi Phil,

We were not able finish the brazing task of our TM4 magnet yesterday. As a result, we could not fill TM4 with LCW before 9:00 AM today.  However, it is likely that we will complete brazing by noon.

As I said, we need about 15-20 gallons to fill our magnet. Can we connect our magnet with LCW and fill our magnet with LCW between 12:30 PM to 2:30 PM today? If not, when can we do it?

Many thanks for the understanding.

Eric

Howdy,

We will circulate LCW in MOLLER TM4 from 9:30 AM 1/23 to 9:30 AM 1/26 with a flow rate about 30 gpm. No energization will occur during this period and therefore no heat will be dumped into the LCW system.

If you have concerns, please let me know.

Thanks a lot for attention.

Eric
