Subject:

Docket No. 50-482: Additional Information Regarding. Main Steam and Feedwater Isolation System (MSFIS) Controls Modification Gentlemen:

Reference 1 provided a license amendment request (LAR) that proposed revisions to Technical Specification (TS) 3.3.2, "Engineered Safety Feature , Actuation System (ESFAS)

Instrumentation," TS 3.7.2, "Main Steam Isolation Valves (MSIVs)," and TS 3.7.3, "Main Feedwater Isolation Valves (MFIVs)." Reference 1 proposed changes to these specifications based on a planned modification to replace the MSIVs and associated actuators, MFIVs and associated actuators, and replacement of the Main Steam and Feedwater Isolation System (MSFIS) controls.

On January 30, 2009, Wolf Creek Nuclear Operating Corporation (WCNOC) was notified of NRC staff concerns regarding an analysis of the replacement MSFIS controls to the requirements of Institute of Electrical and Electronics Engineers (IEEE) Std 603-1998, "IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations,' and use'of IEEE Std 603-1998 in WCNOC Specification J-105A(Q) for Replacement MSFIS System. The specific NRC staff concern is that referencing IEEE Std 603-1998 in the WCNOC Specification P.O. Box 411 / Burlington, KS 66839 /Phone: (620) 364-8831 An Equal Opportunity Employer M/F/HC/VET J .

ET 09-0008 Page 2 of 3 would require an exemption to 10 CFR 50.55a, "Codes and standards," paragraph (h),

"Protections and safety systems." Paragraph (h) specifies that protection systems meet the requirements stated in either IEEE Std 279 or IEEE Std 603-1991. Specification J-105A(Q) has been revised to reference IEEE Std 603-1991 and is provided in the Enclosure.

Reference 2 identified additional documentation required by the NRC staff to complete the acceptance review of the application. Item 20 requested an analysis of all IEEE Std 603 requirements with a description of how the Field Programmable Gate Array (FPGA) MSFIS actuation controls meets these requirements. In response to this item, Enclosure 22 to Reference 3 provided an analysis of replacement MSFIS controls to the requirements of IEEE Std 603-1998. This was based on Revision 2 of Specifications J105A(Q) that referenced IEEE Std 603-1998. Reference 3 submitted a "Matrix of IEEE 7-4.3.2 Requirements to MSFIS Controls Design" to address a NRC staff request from a September 25, 2007 teleconference.

This matrix also includes cross references to the IEEE Std 603-1998 requirements. Based on discussions in a teleconference between NRC staff and WCNOC personnel on February 4, 2009, it is WCNOC's understanding that this information is not required and is therefore withdrawing Enclosure 22 to Reference 3 and Reference 4.

The documentation provided in the Enclosure does not impact the conclusions of the No Significant Hazards Consideration provided in Reference 1. In accordance with 10 CFR 50.91, a copy of the submittal is being provided to the designated Kansas State official.

This letter contains no commitments. If you have any questions concerning this matter, please contact me at (620) 364-4084, or Mr. Richard D. Flannigan at (620) 364-4117.

FORM APF-05-004-04, Rev. 0 1.0 SCOPE The Scope of Work is to replace various parts of the existing safety-related electronic Main Steam and Feedwater Isolation System (MSFIS) with a safety-related logic-controller-based system to perform the control functions of the Main Steam Isolation Valves (MSIVs) and Main Feedwater Isolation Valves (MFIVs). The Replacement MSFIS System 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 System, existing and replacement, has 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 System 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 existing and replacement MSFIS Systems are both considered digital in that they deal with ON-OFF inputs and outputs, and there are no analog / magnitude inputs and outputs involved. However, the systems do not have general digital computer components and characteristics such as a clock-driven central processing unit in continuous operation.

The Replacement MSFIS System project shall be worked by two suppliers; 1) Control System Supplier (Controls Seller)

2) Qualification Supplier (Qualification Seller). The Controls Seller is responsible for the selection, assembly, implementation testing, dedication, and implementation of the Replacement MSFIS System. The Qualification Seller is responsible for the Qualification of the Replacement MSFIS System supplied by the Controls Seller. The Controls Seller and the Qualification Seller shall each be a qualified I OCFR50 Appendix B vendor.

The Buyer will perform an overall independent Validation & Verification of the Replacement MSFIS System development and implementation. Final approval of the Replacement MSFIS System by the Buyer shall be required to ensure the requirements of this document have been fully satisfied.

1.1 Work Included

1. The Controls Seller's scope of work focuses on selection and production of new items for replacement of existing items, the Controls Seller is also responsible for system selection to perform the required system functions. The Qualification Seller is responsible for factors such as seismic qualification, etc., applied to the final integrated system and cabinet configuration.

2. Replacement of the existing MSFIS system components in the form of circuit cards. The existing system includes input buffer cards, valve controller module cards, and relay driver cards. These components shall be replaced by a logic-controller-based system which performs the required functions of the replacement MSIVs and MFIVs. Replacement of the racks which contain and support these circuit cards is included if required by the configuration, quantity, ambient temperature / cooling, back-plane wiring, or any other configuration aspect of the replacement circuit cards.

3. Appropriate test capability for the replacement system. The existing system's Manual Test Panel may be re-used as is, modified as appropriate, or completely replaced as required by the replacement system configuration.

4. Provide an output dry contact or equivalent in each MSFIS Cabinet for a new summary trouble alarm.

5. Replacement of the existing system power supply modules with redundant hot-swappable power supply modules.

6. Supply of new surge suppressors.

FORM APF-05-004-04, Rev. 0

7. Mounting hardware and wiring devices as necessary to mount the replacement components and interconnect them to each other and existing circuits.

8. Required new portable test equipment.

9. Initial stock of repair parts for twenty years' use.

Buyer acknowledges that the nature of a replacement system intended for installation in existing cabinets in the Buyer's plant is that it will consist of many small items but no unifying structure. Thus, the items are packed and shipped individually or in groups and require individual installation into the Buyer's cabinets at the Buyer's plant.

Buyer acknowledges that some of the items specified may be delivered ready for use in the form of "One lot - mounting hardware and wiring devices."

1.2 Related Work Not Included

1. Installation of Replacement MSFIS System components in the MSFIS Cabinets.

2. The replacement MSIVs and MFIVs will be supplied and installed by others.

3. Connection of field cables to the replacement MSIVs and MFIVs will be done by others.

4. New field cable required for the new summary trouble alarm.

5. The overall project will also include electrical equipment and circuit changes outside the scope of this Specification.

2.0 OBJECTIVE The plant's existing Main Steam Isolation Valves and Main Feedwater Isolation Valves have electro-pneumatic-hydraulic actuators. The existing valves have a discrete-component solid-state electronic control system to control the valve actuators and thus the valves. The valves will be replaced by new valves with system-medium actuators, rather than the electro-pneumatic-hydraulic actuators. The objective of this Specification is to procure an advanced-hardware-based control system which will have appropriate logic to control the replacement valves' system-medium actuators. The replacement'control system will be custom-selected from available hardware items so that it will not utilize nor depend upon any program software.

The responsibility of the Controls Seller shall be limited to energizing and de-energizing the system outputs as specified.

Note that the actuators are divided into two "sides," and that each side is controlled by three solenoids labeled MV1, MV3, and MV5 for one side, and MV2, MV4, and MV6 for the other side. The three MSFIS outputs associated with each side of each valve are likewise identified as outputs MV1, MV3, and MV5 for one side, and MV2, MV4, and MV6 for the other side.

There must be no connection nor communication of information within the MSFIS between the controls for the two sides of any valve. The states of the outputs for the two sides of a valve must be completely independent of one another. This separation is accomplished by assigning the two "sides" of each valve to opposite Channels MSFIS Cabinets.

a. Output States and Commands

1) Output States There are three output states for each valve actuator; 1) CLOSE, 2) KEEP CLOSED, and 3)

OPEN. The normal state (during normal plant operations) for each MSIV and FWIV is OPEN. The required output to each solenoid for all three of the valve actuator states is shown below.

Outputs to Outputs to MSIV / MFIV MSIV / MFIV MV1, 3,5 Side MV2, 4,6 Side Output State Symbol MV1 MV3 MV5 MV2 MV4 MV6 CLOSE C KEEP CLOSED KC + +

OPEN 0 + + + +

Key: + = energized

- = de-energized The fail safe output state shall be defined as maintaining the current output state when a failure is identified

2) Commands There are four commands; 1) All Close, 2) ESFAS, 3) Close, and 4) Open.

The All Close command is generated from the ALL CLOSE pushbutton hand switch on the Main Control Board (separate switches for MSIVs and MFIVs). The All Close command shall REV SPECIFICATION NUMBER .- 105A(O) .

Page 9

FORM APF-05-004-04, Rev. 0 place the CLOSE output state for all four valves for the respective switch, MSIV or MFIV.

The output state shall remain CLOSE for 60sec +/- 1sec after All Close command was initiated. After the 60sec time delay the output shall be changed to KEEP CLOSED.

The ESFAS command is generated from the Solid State Protection System. The Solid State Protection System provides the inputs to the MSFIS from a separate slave relay for each the MSIVs and MFIVs. Each slave relay provides four contacts into.the MSFIS, one contact for each valve. The four contacts from a particular slave relay for either the MSIVs or MFIVs shall be evaluated using 2-out-of-4-voting. The 2-out-of-4 vote shall be required for a valid ESFAS command. The ESFAS command shall place the CLOSE output state on all four valves of the particular system MSIV or MFIV. Note: Under Normal Operating conditions the four ESFAS commands will come in at the same time, as they are derived from the same slave relay coil. The output state shall remain CLOSE for 60sec +/- 1sec after the ESFAS command was initiated. After the 60sec time delay the output shall be changed to KEEP CLOSED.

The Close command is defined as a close signal to one valve, MSIV or MFIV, initiated by the valve's assigned individual NORMAL-CLOSE-OPEN pushbutton hand switch on the Main Control Board. The Close command shall place the CLOSE output state for the particular valve associated with the NORMAL-CLOSE-OPEN pushbutton hand switch that was actuated. The output state shall remain CLOSE for 60 sec +/- 1 sec after the Close command was initiated. After the 60sec time delay the output shall be changed to KEEP CLOSED.

The Open command is defined as an open signal to one valve, MSIV or MFIV, initiated by the valve's assigned individual NORMAL-CLOSE-OPEN pushbutton hand switch on the Main Control Board. The Open command shall place the OPEN output state for the particular valve associated with the NORMAL-CLOSE-OPEN pushbutton hand switch that was actuated.

b. Command Priorities

1) The command priorities are as follows when the MSFIS system is in OPERATE mode (see section 5.2.6 for OPERATE mode).

All Close, Close, and ESFAS have equal priority. The Open command will be ignored while the All Close, Close, or ESFAS command(s) are present. Further the Open command will be ignored until the CLOSE to KEEP CLOSE time delay has expired.

2) The command priorities are as follows when the MSFIS system is in BYPASS mode (see section 5.2.6 for BYPASS mode).

All Close, Close, ESFAS, and Open commands shall not cause a change in system outputs while the system is in BYPASS mode.

FORM APF-05-004-04, Rev. 0 5.2.6 Provisions for System Test of the Safety Function The existing MSFIS System includes provision to permit complete testing of the safety function (ESFAS command) of each actuation train for each valve. The Replacement MSFIS System shall also have such provision for complete testing of the safety function of each actuation train for each valve.

Overlapping of test schemes may be utilized in order to ensure complete coverage of the test program. It shall be possible to conduct all tests during plant operation. Performance of fully automatic system tests shall not interfere with the system's operation during presence of any actuation input.

Controls Seller shall provide three test types or detection capabilities to verify the proper operation of the Replacement MSFIS System to perform the intended safety function. The three types of tests or detection capabilities shall be;

1) Manual System Test:

a. Ability to manually test required inputs and/or outputs required to perform the safety function

2) Manually Initiated Automatic Test:

a. Ability to manually initiate automatic test(s) and/or detection capabilities which monitor or test the ability of the system to perform the required safety function.

3) Automatic Exception Detection:

a. The system shall be designed such that the system is fully deterministic and shall automatically detect improper operation of the system's ability to perform the required safety function.

All system test and detection capabilities shall be validated & verified by Buyer.

The MSFIS test circuits shall provide one contact set for each actuation train for each valve. The contacts shall be open for normal operation and shall close at the appropriate test step as described below. These contacts will be used to enable test circuits in the Safeguards Test Cabinets to verify proper transmission and to verify the response to the ESFAS command.

a. BYPASS / OPERATE Mode Selection

1) Selection Means shall be provided to select BYPASS or OPERATE mode for each actuation train for each valve. The selection of BYPASS shall maintain the valve in the as found condition and shall not cause a change in system outputs.. The selection of BYPASS shall only impact the particular actuation train and particular valve for which the BYPASS is selected. Except as indicated in the following paragraph, each change in mode shall require a positive manual action such as pushing a button, flipping a switch, or turning a switch (releasing a pushbutton or switch is not considered to be positive action, and shall cause no change in mode).

The actuation train for a particular side of a particular valve shall enter BYPASS mode upon command. There shall be one exception to this, which is the situation where the output state is CLOSE and the 60 sec delay is active, in this situation the CLOSE state must be completed and the 60 sec time complete prior to entering the BYPASS mode.

2) Indication An indicating light /LED shall be provided for each actuation train for each valve. This light

/ LED shall be "ON" whenever BYPASS mode is in effect.
