ALS Class I E Controls: ALS Architecture Evaluation 1I Purpose andScope ~ i~2J 1 i.1i~.i:

1.1 Purpose The purpose of this document is to evaluate the ALS architecture for use at WCGS. The ALS will initially be installed as a replacement for the existing MSFIS controls. This evaluation will focus on this particular replacement, but also serve as a generic evaluation for modifications going forward.

1.2 Scope of Evaluation As stated in the purpose this evaluation is focused on the MSFIS Controls replacement modification, but also serves as a generic evaluation of the ALS for use at WCGS.

The scope of the MSFIS modification as defined by J-105A(Q) "Replacement MSFIS System" is to replace the existing controls with a control system based on the Advanced Logic System (ALS) technology.

The MSFIS Controls Replacement Project replaces the existing safety related electronic MSFIS with a hardware-based system to perform the control functions of the MSIVs and MFIVs. The replacement MSFIS will be installed in conjunction with replacement of the existing electro-pneumatic-hydraulic MSIVs and MFIVs by new MSIVs and MFIVs with system-medium actuators. The MSFIS controls, existing and replacement, have two redundant subsystems located in separate cabinets:

MSFIS Channel 1 (1) located in MSFIS Cabinet SA075A MSFIS Channel IV (4) located in MSFIS Cabinet SA075B The replacement project will retain the existing cabinets, external power supply feeds, and channel separation scheme in the overall plant configuration. The replacement project will include changes to the functions by which the replacement MSFIS controls the replacement MSIVs and MFIVs. These changes account for the differences in the function of the existing and replacement MSIVs and MFIVs. That is, electro-pneumatic-hydraulic actuators replaced by system-medium actuators.

The replacement project will implement a new digital control system, new power supplies, new assembly panels, and new vendor wiring. The replacement project will retain, without modifications, the existing cabinets including mechanical structures used to mount racks and components and field-wiring and terminal blocks within the cabinets.

The replacement project will modify the functionality of the current MSFIS per J-105A (Q) Rev. 2 requirements.

[1] This will include changes to the functions by which the replacement MSFIS controls the replacement MSIVs and MFIVs. These changes account for the differences in the function of the existing and replacement MSIVs and MFIVs. That is, electro-pneumatic-hydraulic actuators replaced by system-medium actuators. The replacement project will not re-use existing electronic boards, sub-racks, interconnecting wiring/cables, fuse blocks, circuit breakers, test panels, switches, indicators, power supplies, actuation relays, assembly panels, and so on, nor will the replacement project include the actual installation of the replacement MSFIS components in the MSFIS cabinets, the new system-medium MSIV / MFIV actuators, or any of the field cables.

After replacement, each cabinet will contain the following components:

ALS Class I E Controls: ALS Architecture Evaluation 2 ALS Architectu.re valuatio'n and Deliverables K' c,d 2.1 2.2 ALS Architecture for the MSFIS replacement The ALS architecture provides the correct solution for the replacement of the MSFIS Controls at WCGS. In addition to the overall aspects discussed in section 2.1, the ALS provides the proper interface for the MSFIS Controls. The table below shows the I/O interface for the MSFIS Controls at WCGS., This I/O interface meets the requirements for the replacement MSFIS Controls at WCGS. The solenoid interface provides additional functionality and eliminates the requirement for an interposing contactor for switching the large solenoids located on the actuators. c,d 2/25/2008 Page 7 of 11 Revision 0 2/25/2008 Page 7 of I I

ALS Class IE Controls: ALS Architecture Evaluation 2.5.2 CS Innovations, 6101-00000, "MSFIS Level 0 Specification" This document provides the Conceptual Design of the Main Steam Feedwater Isolation System (MSFIS) controls replacement project for Wolf Creek Generating Station. The conceptual design is the initial look at what the MSFIS Controls replacement looks like using the ALS.

2.5.3 CS Innovations, 6101-00002, "MSFIS System Specification" This document addresses the overall system specifications of the replacement system for the safety related Main Steam and Feedwater Isolation System (MSFIS) controls for Wolf Creek Generating Station (WCGS). The document provides an overall description of the replacement MSFIS based on the Advanced Logic System (ALS)

The document addresses the overall MSFIS implementation, as well as the specification for the cabinet content and detailed specification of the assembly panel.

2.6 Conclusion of Evaluation The ALS architecture is found to be acceptable for use as MSFIS Controls replacement as well as a generic safety related controls platform at WCGS. This evaluation is based on the final acceptance by WCNOC of the CS Innovations documentation, drawings, and actual equipment as discussed in this document.
