Open Item with regard to Incore Instrumentation System In order for staff to review the acceptability of the Incore Instrumentation System (IIS) provide a brief system description of IIS and its regulatory compliance. In your discussion include the discussion of WINCISE and BEACON system which are part of the IIS. Also provide the differences between the system used at WBN Unit 1 vs at Unit 2, eg. Movable vs fixed IIS. For WINCISE provide the basis for acceptance. If this system has been accepted by the staff previously at some other plant then provide the reference to that SE. If this has not been evaluated by the staff previously, then provide the effect of CCF of this system and its effect on safety system or chapter 15 analysis. Does this have any interconnection with safety system? For Beacon provide the acceptability of this system. I believe that this system was accepted at WBN Unit 1. If that is the case then provide the reference to that review. Also provide any differences of this system to the one at WBN Unit 1 system.
