PREPARE FOR SAMPLING

1. Verify shielded Particulate/Iodine (P/I) sample is loaded in PIS#1 or PIS#2.

IF P/I sample NOT loaded, THEN do the following:

a.

Verify which PIS to be loaded.

b.

Prepare a new P/I holder.

c.

Line up PIS#1 (PIS#2) by opening V-13 (V-I1) and V-14 (V-12).

CAUTION:

Although analog outputs will be frozen at last value, digital ports and log commands remain operational while in Program Mode.

NOTE:

Flow rate through the PIS is totalized by FIT-2 (the flow transmitter for the accident sampling flow path) and by the Local Processing Unit (LPU).

Both totalizers must be reset when switching or replacing PIS samples.

Only the Local Display Unit (LDU) totalizer resets when the vent monitor switches from NORMAL mode to ACCIDENT mode and places the shielded PIS in service.
