WO WORK PLAN Change Wiring of Flow Controllers 2YIC-926A For IWP 95-035-01 Spray Additive Tank System on C01 In The Control May 30,1996 Room UNIT 2 ,

1. SCOPE 1.1 The scope of this work plan is to implement wiring changes to correct indication on the spray additive tank flow controller 2YIC-926A on C01 in the control room and also to eliminate excess current of 145mA from flowing through the output meter and R72, exceeding the power rating of the resistor, which would damage the resistor.

1.2 The purpose of this modification is to eliminate excess current of 145mA flowing through the output meter and R72 and provide improved indications on the controller 2YIC-926A.

l 1.3 This approach of this installation is to remove 2YIC-926A from C01 and perform wiring changes within the controller. The work will be directed by this work plan.

1.4 This work is QA Scope.

1.5 Support Requirements

1. 5.1 Operations: Equipment isolation, tagouts
1. 5.2 I & C: Modification installation and testing

2.2 Installation Preparation Activities:

2.2.1 In this installation, no material is required. If any additional wiring is needed, use wiring similar to the existing wiring in the controller.

Record Quality Assurance Release (QAR) numbers on the work orders.

2.3 Identification of Permits Required 2.3.1 The work order for this work plan has been written and submitted to CHAMPS. The WO number is 9604777.

2.4 Ooerational Installation Prereauisites:

2.4.1 The plant condition required is cold shutdown or refueling.

2.4.2 The spray additive tank outlet valve,2SI-831 A must be tagged shut as the spray additive tank suction valve,2SI-836A will be stroked following the installation of the modification per Operating Procedure 3C(OP-3C)

" Hot Shutdown To Cold Shutdown."

2.4.3 Release For Installation All of the above operational installation prerequisites have been met and it is acceptable to proceed with the installation.

4. TESTING 4.1 Testina Prereouisites:

4.1.1 A stopwatch is needed for valve stroke testing.

4.2 Testine Information: l l

4.2.1 The intent of this testing is to verify the indicator on the controller indicates open when the switch is off. Also these wiring changes completed above should now eliminates excess current flowing through l the R72 resistor.

NOTE 1: The valve stroke open time is defined as the elppsed dme when the valve controller is positioned to the maximum open speedposition in the manualmode and the time that the valve open light is received on the active status board.

NOTE 2: The valve stroke closed dme is defEned as the elapsed time when the valve controller is posidened to the maximum closed speedposition in the manualmode and the time that the valve ceases motion in the closed direction by local observation.
