Thisprocedure assumes that the system is configmdper CL-6A, normaloperation.

NOTE 2: Ifsystem was drainedpreviously, N/A Section 3.1.

5,1 Draining CC water from the exass letdown system:

NOTE:

Ifdraining of1P-1A and/or1P-1B CC water system is also required, then it should be drainedper ORT 68 and/or 69, respectively, prior to draining the excess letdown system per thisprocedure.

ICC-766 j

ICC-865A 1

1CC-865B aCAUTIONa ONLY CLEAN AND UNCONTAMINATED i

CHROMATED WATER MAY BE RETURNED TO THE CC SYSTEM.

NOTE:

Reference Figure 1for transfer system assembly.

5,1.2 Locate a gigan 55 gallon barrel with modified barrel lid and transfer pump directly below ICC-1413, excess letdown CC return test connection, on El. 8' of containment.

1_

5.1.3 Remove the 3/8" x 3/4" adapter at 1CC-1413 and replace with a 3/4" x 3/4" barbed hose connection fitting. Save 3/8" by 3/4" 4

fitting.

5.1.4 Connect a cut-to-length 3/4" ID by 3/16" wall thickness tygon hose between the transfer pump discharge and ICC-1413.

ONCE SYSTEM DRAINAGE / TRANSFER IS STARTED, AN OPERATOR MUST BE CONTINUOUSLY PRESENT AT THE 55 GALLON DRAIN COLLECTING BARREL TO MONITOR THE TRANSFER OPERATION OR THE PUMP SECURED AND VALVES ICC-1413, 1414 AND 1415 SHUT. FAILURE TO MONITOR THE TRANSFER SYSTEM MAY RESULT IN A CC SPILL IN CONTAINMENT AND A LOSS OF CC WATER FROM THE OPERATING PORTION OF THE CC SYSTEM TO THE CONTAINMENT SUMP.

5.1.10 Open 1CC-1414 and 1415, CC supply low point drains.

5.1.11 Pressurize the CC supply to excess letdown from SA via 1CC-D8 to facilitate draining.

5.1.12 When only air is issuing from ICC-1414 and 1415, then shut 1CC-D8 and disconnect the SA supply.

I

• CAUTION

• DO NOT ALLOW THE TRANSFER PUMP TO j

RUN DRY OR PUMP EXCESS AIR INTO THE CC RETURN SYSTEM OR AIR BINDING OF THE OPERATING CC PUMP MAY RESULT.

NOTE:

The Ted self-priming transferpungp is a limited dutypump.

Thepump should be ga ::d atfullflow by starting and stopping thepump versus run continuously on throttled recirc to maintain constant barrellevel.

5.1.13 Pump the contents of the 55 gallon drain collecting barrel to the 4

CC water system via 1CC-1413 until nearly dry.

5.1.14 When all systems are drained including the RCP loops per ORT 68 and 69, ifrequired, then add ~5 gallons of DI. vater to the barrel. Flush the pump on recire, then pump the remainder of the diluted chromates to the system via 1CC-1413.
