1.0 PURPOSE AND SCOPE

1.1 Purpose

This procedure provides instructions for operating and cleaning the PB-1 and PB-2 Seal

Water System and filters.

1.2 Scope

1.2.1 This procedure applies to the seal water system and filters for the PB-1 and

PB-2 pumps at 242-A Evaporator.

1.2.2 This procedure interfaces with other nuclear facilities, i.e., the interface

between Tank Farm and the 242-A Evaporator.

2.0 INFORMATION

2.1 General Information

2.1.1 The seal water is filtered through either a 1-3 micron, 5 micron, or a

10 micron sock filter located on the fifth floor of Condenser Room.

2.1.2 The seal water system can use two sources of water for the seals: either

filtered raw water or process condensate. Valve HV-CA1-10 is the

controlling valve which directs either filtered raw water or process

condensate to the pump seals and de-entrainer sprays. The process

condensate is pumped by pump P-C106 through CUNO ™

filters F-C-5 or F-C-4 up to HV-CA1-10.

2.1.3 During startup or normal operation of the 105 and 105A seal water booster

pumps, a pump that is in “MANUAL” can only be started by a command

from the MCS. Either pump may be used as the primary, and is set to

MANUAL and ON status. The other pump (if operable) is set to AUTO and

OFF status so it can start automatically, if necessary, due to a low flow or low

pressure condition. When first started, if the primary pump does not clear an

existing low flow/low pressure alarm, or a low flow/low pressure alarm

activates while a booster pump is in operation, it starts a two minute timer.

After a two minute delay following receiving a low flow or low pressure

alarm sensed by one of the following, FIT-CA1-1, FIT-CA1-2, PT-CA1-9 or

PT-CA1-10, the standby pump (in AUTO) will automatically start. If at the

end of these two minutes the low pressure or low flow condition has not

cleared, the backup pump will start. If the low pressure or low flow

condition still does not clear, then two minutes later (following start of the

backup pump) the (four minute) low pressure/flow timer will stop the first

pump. After an additional two minutes with the low pressure or low flow

condition not clear, the (four minute) low pressure/flow timer for the standby

pump will stop that pump.

3.0 PRECAUTIONS AND LIMITATIONS

3.1 Personnel Safety

3.1.1 The hazards associated with the performance of this procedure have been

determined to be covered by the GHA.

3.2 Equipment Safety

CAUTION - Allowing process condensate to flow through booster pumps P-C-105 and

P-C-105A for an extended period may damage seals.

3.2.1 A loss of seal water due to misalignment of valving or other means to PB-1

and PB-2 Recirculation and Slurry Pumps may cause permanent damage to

the seals.

3.3 Radiation and Contamination Control

3.3.1 Work in radiological areas will be performed using a Radiological Work

Permit (RWP) following review by Radiological Control per

TFC-ESHQ-RP_RWP-C-03, ALARA Work Planning.

3.3.1 Opening or performing maintenance on sock filters (F-CA-L or F-CA-R)

requires HPT coverage and contamination controls (Pre and Post Surveys at a

minimum).

3.3.2 A Radiological Work Permit may be used to perform this procedure

contingent upon no part of the activity being performed within a High

Contamination Area, High Radiation Area, or Airborne Radioactivity Area.

The opening of any system or component within a Radiological Area requires

the presence of a Health Physics Technician to verify contamination control.

3.4 Environmental Compliance

3.4.1 Report any information concerning spills or releases to the appropriate Shift

Office and Environmental per TF-REC-001. This includes spills or releases

to secondary containment.

3.4.2 Process Condensate is considered a Dangerous Waste under WAC 173-303.

Process Condensate and items that are generated from contact with Process

Condensate upon disposal must be managed as Dangerous or Mixed Waste.
