Answer 2

• 70 - 200 ˚F:*
• *475 psig**
• 220 - 380 ˚F:*
• *660 psig**

Uses Auct Low WR T_C / PT-404

• Note:*
• Normal PORV setpoint is 2335 psig. (B/U pressure channel)*

Question 3

• LOT 506.01 Solid Plant Operations*
• • *

At what pressure will the PORV (PCV-655A) lift when COMS is armed?

Answer 3

• 70 - 200 ˚F:*
• *515 psig**
• 220 - 380 ˚F:*
• *730 psig**

Uses Auct Low WR T_H / PT-403

• Note:*
• Normal PORV setpoint is ≈ 2335 psig. (Master pressure controller 87.5%)*

Question 4

• LOT 506.01 Solid Plant Operations*
• • *

When is COMS required to be armed?

Answer 4

≤ 350 ˚F

• PCV-655A (Auct Low WR T_H / PT-403)
• PCV-656A (Auct Low WR T_C / PT-404)

COMS controller completely independent of master pressure controller.

• Note:*
• Manually armed on CP004*
