MWR WORK PLAN ,

l Residual IIeat Removal (RIIR) controller repositioning. MR 92-141 Work Order # 9605772 September 24,1996 i UNIT 2 Step No. Work Plan Description Initials Date The scope of this work plan is to reposition RIIR controllers 2IIC-00624 and 211C-00625 as well as 211C-00626 on main control board shelf 2CO3 - 14. The simulator configuration is to be updated as well.

The purpose of this work plan is to reposition 2IIC-00624 and 211C-00625 RIIR controller positions. These controllers currently do not conform to plant installation and design guidelines as stated in DG-G01 section 1.2.2 and section 2.5. In addition, controller 211C-00626 will be moved to a position in between 211C-00624 and 211C-00625 to further separate the 'A' train and 'll' train components.

This work plan requires that Unit #2 be in full core offload and will be accomplished during the U2R22 outage.

  • Due to sufficient existing wire length this work plan does not require new wiring to be used.

l A. Desenbe the modification, procedure change, test, or experiment and its expected effects. belude 1 interim configurations or conditions.

Unit #2 Residual Heat Removal (RHR) controllers,2HC-624 and 2HC-625 on 2C03 display an "A" train left and "B" train right configuration. Per Design and Installation Guideline, DG-G01, the convention for Unit #2 should be train "A" right and train "B" left. Modification MR 92-141 will correct this deficiency and also position controller 2HC-626 between 2HC-624 and 2HC-625, in order to improve the separation of the controllers.

Repositioning the controllers will entail: Disconnecting power to the three controllers, Disconnecting connection cords on the

back of each individual controller, Removal and repositioning of terminal blocks on the back of shelf 14 of MCB 2CO3 per the
modified position scheme, Removal and repositioning of applicable RHR controllers on MCB 2CO3 per the modified position
. scheme, Connecting cords on the back of each individual controller, Connecting power to the three controllers. Operation and

)

! performance of the three controllers will be checked with the performance of a Post Maintenance Test for each of the controllers.  ;

I The PMT will consist of a stroke test of each of the valves via their respective controllers.

Ifyes, complete Sections 4 and 3.

D. Basis for determination that a safety evaluation is not required:

1 Modification MR 92-141 will reposition the existing residual heat removal (RHR) controllers on the main contro' board 2C03 in order to maintain the "A" train right and "B" train left configuration used at PBNP. This repositioning will correct the discrepancies to Design and Installation Guideline, DG-G01.

This modification changes the physical location of the RHR controllers,2HC-624,2HC-625, and 2HC-626. It does not change the operation or function of the controllers. The modification will be worked and completed during U2R22 when Unit 2 is in full

core ofnoad.

l The operation and function of the RHR controllers will be checked with the performance of a Post Maintenance Test for each of the controllers. The PMT will consist of a stroke test of each of the valves via their respective controllers verifing that the correct j valve strokes from fully open to fully closed.

This modification does not affect the Independent Spent Fuel Storage Installation (ISFSI).  !
