/ ARKANSAS NUCLEAR ONE aEvisiON i DATE io/22/8i CHANGE DATE 1.0 PURPOSE 1.1 To provide for transfer of Spent Resin to Spent Resin Tank 2T-13 from the following:
1.1.1 Waste Concentration Ion Exchanger 1.1.2 CVCS Ion Exchanger .
1.1.3 Fuel Pool Ion Exchanger 1.1.4 Preconcentrator Ion Exchanger 1.1.5 Boric Acid Condensate Ion Exchanger
2.0 DESCRIPTION
2.1 The Spent Resin Tank is designed to provide a one-year hold up capacity for spent resin to allow decay of short-lived activity.
2.2 Spent Resin is sluiced into the Spent Resin Tank from the various
. icn exchangers in the NSS Auxiliary System. Excess water which is accumulated in the Spent Resin Tank during the transfer of spent resin is drained to the Waste Tanks.
2.3 The Spent Resin Tank is equipped with a level indicator and high level alarm.
