1.0 PURPOSE

1.1 This alarm response procedure provides guidance to Nuclear Chemical Operators for

responding to alarms associated with graphic “Primary Exhaust Trains” (17 or graphic

#17) on the AY/AZ ventilation system Monitor and Control System (MCS), or the Tank

Farms Monitor and Control System (TFMCS).

1.2 Environmental Compliance

Tank farm ventilation systems and exhaust monitoring systems are regulated under

Washington Administrative Code (WAC) Chapters 173-400, 173-401, 173-460 and 246-

247 and applicable Notices of Construction (NOC) issued to ensure compliance with

these regulations. To ensure reporting requirements are met, all planned and unplanned

outages of tank farm ventilation and exhaust monitoring systems, including portable

exhausters, must be reported to the appropriate shift office for evaluation with

Environmental for possible notifications in compliance with TFC-ESHQ-ENV_FS-C-01.

2.0 OPERATION

2.1 OPERATE MCS in accordance with procedure TO-060-356.

2.2 RESET Object Error (OE) and Priority Command Interlock conditions or alarms not

identified in this ARP with procedure TO-060-350.

HIGH

Source: PI-AZK1-1A Setpoint: -7.0 ” WC

Alarm Class: Technical Safety Requirement (LCO 3.1, DST Primary Tank Ventilation Systems, and

LCO 3.4, DST Induced Gas Release Event Flammable Gas Control).

Alarm Description: Primary Vent Header 1A Pressure high (Low vacuum)

NOTE - Alarm Response Procedures are not designed for, nor intended to be applied to, "expected"

alarms generated by approved work activities or procedures.

PI-AZK1-1A is HIGH

Stack flow is less than 200 Scfm.

Immediate Actions:

[1] CHECK instrument has not failed by comparing with PI-AZK1-1B.

[2] IF instrument PI-AZK1-1A has failed AND

IF fan AZ-K1-5-1A will be the operating fan, ENSURE fan AZ-K1-5-1A is operated in

MANUAL mode.

[3] IF AZ-K1-5-1A Fan is operating, ENSURE PIC-AZK1-1A is in AUTO or MANUAL

mode with an adequate SETPOINT or OUTPUT value.

[4] ENSURE differential pressures on the HEME, Primary condenser, and A filter train are

in normal range.

[5] ENSURE primary ventilation dampers are in proper alignment using graphic screens

2. MK-AZK1-1B, MK-AZK1-2B, or MK-AZK105-1B1 closed, which may cause high

pressure (low vacuum) at the sensing point

3. A train filter differential pressures high (plugged filter)

4. Primary condenser or HEME differential pressure high

5. Ongoing maintenance PMs.

6. Fan set point lost or incorrect after a power loss or outage.
