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.
