Reference:

1) Letter ET 07-0004, dated March 14, 2007, from T. J. Garrett, WCNOC, to USNRC

Subject:

Docket No. 50-482: NRC Request for 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.

A second site visit to CS Innovations was made on December 10 and 11, 2008, for the purposes of reviewing the dual diverse core design methodology that was implemented as a result of discussions with the NRC Staff the week of November 17, 2008. During the site visit, the remaining information that the NRC Staff required to support the review of the LAR was identified. On December 12, 2008, Wolf Creek Nuclear Operating Corporation (WCNOC) sent to the NRC by electronic mail the list of the identified information needed for the NRC staff to complete its review. Attachment I provides in table format the list of identified information and the associated document(s) for the information requested. The Enclosures contain the additional information requested by the NRC.

During this site visit, a discussion was held concerning the programming of blank Advanced Logic System (ALS) boards by WCNOC personnel. WCNOC currently does not have the capability to program blank ALS boards or re-program boards that are to be installed in the field. If this capability were to be employed;. WCNOC would develop the required processes and procedures in support of this activity. WCNOC has discussed in letter ET 08-0014 the application of spare components in Section 1.6 of the Maintenance Plan for the ALS, controls. AA)"

WM 09-0001 Page 2 of 5 Additionally, during this site visit, the cyber security requirements for the ALS and the implementation at Wolf Creek Generating Station (WCGS) was discussed. The ALS controls equipment provides the ability for the personnel to connect to the system using a laptop computer, called an ALS Service Unit (ASU), for the purposes of diagnostics and troubleshooting. The operate/bypass switch for the valves within the specific ALS rack is physically placed in bypass prior to the ASU rbeing connected to that ALS rack. This requirement will be implemented administratively within plant procedures. Only one ALS rack within the overall system shall have an ASU connected at any given time. These requirements have been incorporated into Revision 2 of the WCNOC Operation Plan (see Enclosure Ill).

Enclosures IV, V, VI, and IX through XXVII provide proprietary CS Innovations LLC documents.

As Enclosures IV, V, VI, and IX through XXVII contain information proprietary to CS Innovations LLC, it is supported by an affidavit signed by CS Innovations LLC, the owner of the information.

The affidavit sets forth the basis on which the information may be withheld from public disclosure by the Commission and addresses with specificity the considerations listed in paragraph (b)(4) of 10 CFR 2.390 of the Commission's regulations. Accordingly, it is respectfully requested that the information, which is proprietary to CS Innovations, be withheld from public disclosure in accordance with 10 CFR 2.390 of the Commission's regulations. The affidavit, along with a CS Innovations LLC authorization letter, 9100-00025, "Application for Withholding Proprietary Information from Public Disclosure," is contained in Enclosure XV.

WCNOC is providing only proprietary versions of Enclosures IV, V, and IX through XXVII as a non-proprietary version would be of no value to the public due to the extent of the proprietary information.

The documentation provided in the Enclosures 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.

Attachment II provides a summary of the regulatory commitments made in this submittal.

If you have any questions concerning this matter, please contact me at (620) 364-4190, 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 10CFR50 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 I1. 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.

REV SPECIFICATION NUMBER J- 105 A(Q) 4 Page 3

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.

REV SPECIFICATION NUMBER J-105A(O) 4 Page 8

FORM APF-05-004-04, Rev. 0 5.2.5 System Operation In response to command signals from various sources, the MSFIS shall energize and de-energize sets of output terminals in accordance with the requirements set forth below. These outputs will be connected by the Buyer to control solenoids in the actuators of the Main Steam Isolation Valves and the Main Feedwater Isolation Valves.

For illustrative purposes, the functional description document for these actuators is included in this specification. Reference will be made to the operation of these actuators and of their component parts; such references are solely for the purposes of discussion.

The Replacement MSFIS System shall measure actual System outputs, compare the outputs to the required output states, and alarm any discrepancies. See section 5.6.7.

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 I REV SPECIFICATION NIJMBER J-I 0,5A(O) 4 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 +/- Isec 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.

REV SPECIFICATION NUMBER J-10.A(O) I 4 Page 10

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.

I EV SPECIFICATION NUMBER J-105A(O) 4 Page 11

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

3) BYPASS Mode Initiation Upon initiation of BYPASS mode for a particular actuation train for a particular valve, the following must be accomplished:

a) Latch the actuation outputs to the as found state.

b) De-energize the status output.

c) Light the BYPASS mode indicator light / LED d) Close the test contacts described in Section 5.2.6 to enable the test circuits in ESFAS.

To prevent accidental valve operation, "a" must occur prior to "d."

4) Return to OPERATE Mode Upon return to OPERATE mode, the following must be accomplished:

a) Open the test contacts (see Section 5.2.6).

b) Unlatch the actuation outputs, extinguish the BYPASS mode indicating light/LED, and release the status output.

b. Testing of Replacement MSFIS System

1) Controls Seller may modify or replace the existing Manual Test Panel as necessary to effectively interface with the Replacement MSFIS System logic-controller-based system and meet all specified requirements.

2) Provisions for testing of the Replacement MSFIS may include portable test equipment and capability to temporarily connect the portable test equipment to the Replacement MSFIS System during performance of testing.

FORM APF-05-004-04, Rev. 0 5.6.3 Power Supply

a. Sources Two separate sources currently supply nominal 125 Volt DC power, one to each MSFIS Channel /

Cabinet. These redundant supplies are used throughout the plant, and complete physical and electrical isolation shall be maintained between them within the Controls Seller's equipment.

The incoming voltage level on all power supply modules will be a nominal 125 Volts DC, normally operated at 135 Volts DC. The designed operating range of the existing 125 Volt DC System is 140 Volts DC to 105 Volts DC.

b. Replacement Power Supply Modules In the existing configuration, each cabinet has two output voltage levels, nominal 48 Volts DC and nominal 15 Volts DC. For the Replacement MSFIS System, the Controls Seller shall provide replacement power supply modules rated at DC voltage level(s) appropriate to feed all of the electrical loads in the Replacement MSFIS System plus any components retained from the existing design. The replacement power supplies shall have an input voltage operating range of 105VDC - 140VDC. The Controls Seller shall also determine whether any separate supplies are required at a given voltage level to separate electronic circuits from the effects of high-current switched loads.

The existing 125 Volt DC System has the capability to deliver a short circuit current of 11,070 Amperes. All electrical protective devices provided by the Controls Seller shall be capable of clearing this short circuit current.

Each voltage level in each cabinet shall have a pair of redundant and parallel power supply modules and capability to shift all load to one module in case of failure of the other one. Each pair of redundant power supply modules shall have provision for hot replacement "swapping" of one module while the other continues in service. Hot replacement by front-pull-out is preferred, but other configurations may be considered. Controls Seller may choose to modify or totally replace the existing power supply rack. Final configuration of the power supply rack and final configuration of the provisions for hot replacement are subject to Buyer's approval.

Each replacement power supply module shall have sufficient capacity to supply all assigned loads with 15% spare capacity while the redundant power supply module is out of service. The system shall have the capability ("health") to detect loss of each power supply module's capability to assume the full load assigned to the redundant pair. Loss of any power supply module's capability ("health") shall be one of the inputs to the Replacement MSFIS System's new summary trouble alarm circuit. Each pair of redundant power supply modules shall have provision for load sharing whenever both are in service and both have no failure detected.

Drawings of the existing power supply distribution scheme are attached as a reference for power supply module capacity. Drawings J-104-00295 and J-104-00296 show the existing power supply scheme before replacement by the redundant power, supply modules with hot replacement capability.

Drawing J- 104-00296 shows the existing distribution of 48 Volts DC power to the output relays as well as to the existing electronic control system. Drawing J-104-00295 shows that the only existing use of 15 Volts DC power is to feed the electronic controller cards of the existing MSFIS System.

c. Outputs The system outputs shall be fused as shown in Appendix B.

SEISMIC QUALIFICATION REQUIREMENTS FOR CLASS 1E CONTROL AND INSTRUMENTATION DEVICES

1. SCOPE 1.1 General This specification attachment establishes acceptable qualification methods and the requirements to verify that Class 1E and other safety-related control and instrumentation devices can perform their specified safety-related functions during and/or following a safe shutdown earthquake, SSE.

The safety-related function of a device will be specified in the device data sheet or procurement specification by using the classifications defined in this document.

The qualification procedure is to test the device on a vibration table which duplicates or exceeds the anticipated vibratory motions of the actual mounting surface on which the device will be mounted. The actual mounting surface may be a control panel, cabinet, console, instrument rack, building wall, piping system, etc. Ultimately, the devices may be located anywhere throughout the power plant, e.g., in the control room area or in the process area.

Although this specification is written primarily for electrical devices, it provisions apply equally to mechanical and electromechanical equipment, e.g., pneumatic instrumentation and air-operated control devices.

1.2 Responsibilities The Buyer, Bechtel Power Corporation, will be responsible for defining the maximum vibratory motions throughout the power plant structure. The testing or analysis facility shall have direct access to the Buyer's project or staff personnel for obtaining'

.explanatory information about this specification, however, any such information will not alter any existing contractual agreements.

Seismic qualification of each Class 1E device shall be the responsibility of the Supplier.

The device purchaser shall be responsible for assuring that the maximum anticipated vibratory motions at the actual device Page 1 Rev 0

Specification No. 10466-J-820 -<

mounting location do not exceed the motions for which the Class 1E device is qualified..

A list of testing facilities will be furnished upon request.

However, selection of the test facility shall be the responsibility of the Supplier.

1.3 Intent -

The intent of this specification attachment is to specify qualification procedures and acceptance criteria that conform to IEEL Standard 344-1975, Recommended Practices for Seismic Qualifications of Class ME Equipment for Nuclear-Power Generating Stations.

1.4 Acceptable Qualification Methods It is recommended that the device manufacturer perform comprehensive, generic, one-time types of tests of standard devices which are used repeatedly in nuclear safety-related applications rather than to requalify the devices for each power plant project. Such a -test program shall be based on a representative number of standard devices.

An acceptable genexic qualification method is to perform fragility-level tests to determine the maximum vibratory motions which can be tolerated before malfunction occurs.

Another acceptable generic qualification method is to qualify a

-device for most U.S. plant locations as defined by the RRS shown in Figure 1 or the RIM shown in Figure 2 as appropriate for the device in question.

Alternatively, a device can be qualified at or above the seismic conditions for a specific power plant. The appropriate project curves are shown in Figures 3 and 4.*

These three alternative test methods are defined further in Section 5.6.

Certain items in a nuclear power plant will be supplied in a number of similar configurations which do not significantly alter the item's response to a given seismic event. Qualification by testing a representative unit and, subsequently, analytically comparing each specific unit with the representative unit, will be acceptable.

Specification IO. 10466-J-820 1.5 Control Panel Assembly Qualification Seismic qualification of Class 1E control panels, consoles, and cabinet assemblies is covered by Specification Attachment 10466-J821.

1.6 Environmental Exposure Prior to Seismic Testing Certain devices, denoted in the procurement specification, must be qualified to withstand long-term exposure to severe ambient conditions. Examples are devices to be located within the reactor containment structure which may be exposed to aging effects of high ambient temperature and radiation. Such devices shall undergo the appropriate aging exposure prior to seismic qualification tests.

2. DEFINITIONS This section defines words in the context in which they are used in this specification. The portions in quotations marks were excerpted from IEEE Standard 34.4.

Definitions of other terms used in this specification are given in IEEE Standard 344..

2.1 Device An individual item of equipment with specific operational functions. Examples are sensors, transmitters, controllers, bistables, indicators, recorders, relays, control switches, etc.

Devices may be mounted in two general categories: (a) on the building structure, control panels, racks, pressure vessels, etc., or (b) line mounted directly in or on piping systems.

2.1.1 Class 1E Devices Devices which are in nuclear safety-related service and to which is applied "The safety classification of the electric equipment and systems that are essential to emergency reactor shutdown, containment isolation, reactor core cooling, and containment and reactor heat removal, or otherwise are essential in preventing significant release of radioactive material to the environment."

For the purpose of this document, Class 1E is defined further to include all devices classified as Seismic Category 1.

Page 3 Rev 1 S -, - , -:.:  :-

Specification No. 10466-J-820 2.2 Fragility Level "The highest level of input excitation, expressed as a function of frequency, that an equipment can withstand and still perform the required Class 1E functions."

2.3 Required Input Ilotion (RIM)

"The required input motion to the equipment under test is the amplitude of acceleration expressed as a function of frequency

'that an equipment shall withstand and still perform the required Class IE functions."

2.4 Required Response Spectrum (RRS)

"The response spectrum issued by the user or his agent as part of his specifications for proof testing, or artifically created to cover future applications. The RRS constitutes a requirement to be met."

2.5 Safe Shutdown Earthquake (SSE)

"That earthquake which produces the maximum vibratory ground motion for which certain structures, systems, and components are designed to remain functional. These structures, systems, and components are those necessary to assure: (1) The integrity of the reactor coolant pressure boundary, (2) The capability to shut down the reactor and maintain it in a safe shutdown conditions, or (3) The capability to prevent or mitigate the consequences of accidents which could result in potential offsite exposures comparable to the guideline exposures of Code of Federal Regulations, Title 10, Part 100 (December 5, 1973)."

2.6 Test Response Spectrum (TRS)

"The response spectrum which is constructed using analysis, or 4erived using spectrum analysis equipment based on the actual motion of the shaker table. When qualifying equipment by utilizing the response spectrum, the TRS is to be compared to the RRS." !i!

3. DEVICE CLASSIFICATIONS Devices requiring seismic qualification are designated as either Qf-1 or Qf-2 as a part of the procurement specification.

Qf-1 shall remain functional during and after an SSE.

Page 4.

, 0, Qf-2 shall remain functional after, but not necessarily during,.

an SSE.

4. FUNCTIONAL REQUIREMENTS 41.1 Operational Conditions All devices shall be tested while in their normal operating condition, i.e., energized or de-energized, pressurized or depressurized. Operating pressure, voltage etc., shall be applied during and after the tests to determine that vibratory conditions shall not produce a malfunction or failure of the device.

The-device qualification test shall consider the extremes of possible variations from nominal values which could result in incipient malfunction,e.g., when the relay coil voltage drops below its lower operating value, the relay contacts may chatter.

Published operating limits for the device shall be used in the direction which is more likely to produce malfunction.

4.1.1 Qf-I Classification Devices tlat are classified as Qf-1 on data sheets shall be operated during testing to demonstrate that vibratory motions can be tolerated without malfunction or failure. Operability shall be monitored and recorded during and after vibratory excitation.

The Qf-1 devices shall be caused to change state during the test, e.g., de-energize the relay coil or trip a bistable unit. The measured parameter, or input signal, shall be varied as necessary to demonstrate compliance with t!he acceptance criteria specified in Section 4.2.

4.2 Acceptance Criteria The acceptance criterion for qualification tests is that there be no device malfunction or failure that would inhibit the nuclear safety-related function of the device.

Unrestricted acceptance shall require that the following minimum conditions shall not occur, as applicable:

a. Loss of output signal, e.g., open or short circuit

b. Output variations greater than the published accuracy over the full range Page 5 Rev 0 I F.- -. 7

Specification No. 1ULbb-J-ZVU

c. Spurious or unwanted output, e.g., relay contact bounce.

NOTE: If contact bounce is detected, the specific data of the test shall be recorded and submitted to the Buyer for written disposition of the deviation.

d. Drift of set point or trip setting greater than the published accuracy over the full range

e. Calibration shift greater than the published accuracy over the full range; this parameter need not be determined during vibratory excitation.

f. Structural failure, e.g., broken or loosened parts or deformation resulting in device failure

g. Loss of required performance characteristic,e.g., ability to change state ho Loss of pressure-boundary integrity, e.g., leakage.

Sufficient instrumentation shall be provided to monitor and record device performance during vibratory excitation, i.e., that each of the above criteria has been satisfied. Malfunctions shall be analyzed to establish causative factors, and suitable remedial steps shall be undertaken prior to retest.

Whenever these criteria are not met, the specific deviation data shall be submitted formally to the Buyer for evaluation of acceptability for specific applications.

5. SEISMIC QUALIFICATION CONDITIONS 5.1 Test Procedures Written test procedures shall be prepared for all tests and submitted to the Buyer as described in the Documentation Section, below. The test procedure shall require the use of a vibration table to produce vibratory motion.

The vibration table motion shall simulate conservatively, both in amplitude and frequency content, the anticipated seismic motions of the actual surfaces on which the device will (can) be mounted in the power Yplant.

Equipment shall be subjected to the acceleration values described in Section 5.6. Vibratory tests shall be conducted over the range of 1 to 40 H1z. However, I to 33 Hz shall be acceptable for tests performed prior to the receipt of the purchase order to which this seismic qualification specification is attached.

Page 6 Rev 0

Specification No. 10466.-J-820 Figure 1 is an RRS and corresponds, in acceleration and frequency values, to the response of single-degree-of-freedom oscillators attached to the vibration table surface on which the test specimen is mounted. The three percent critical damping spectrum shall be used as the PaRS unless written permission to deviate is granted by the Buyer. Line-mounted devices shall refer to Figure 2, which is the RIM of the test table.

5.2 Vibration Table Excitation (Wave Form)

The preferred excitation wave form is random motion; line-mounted devices may also be qualified by a resonance search and a sine dwell at each resonance. The resonance search shall consist of a sine sweep at two octaves per minute and with an amplitude at least 20 percent of the RIM. Testing with other wave form characteristics than those described in this paragraph mnay be acceptable, depending upon the particular test in question.

However, test wave forms other than these shall be justified adequately for each type of device being qualified and its intended mounting arrangements.

The wave-form characteristics of the proposed test input motion shall be such that the TRS equals or exceeds the RRIS for nonline-mounted devices or that the test table motion equals or exceeds the RIM for line-mounted devices. Test motions other than random shall be in conformance with the criteria of IEEE-314, Section 6.6, Test Methods.

5.3 Direction of Vibratory Motion 5.3.1 RRS Testing The input motion shall be applied simultaneously to the vertical axis and a horizontal axis parallel to the front surface of the equipment when the equipment is in its normal mounting position.

Independent random inputs are preferred, and, if used, the test shall be perforried in two steps with the equipment rotated 900 in the horizontal plane for the second step. If in-phase inputs are used, four tests should be run: first, with the inputs in phase; next, with one input 1800 out of phase; next, with the equipment rotated 900 horizontally and the inputs in phase; and, finally, with the same equipment orientation but with one input 1800 out of phase. Any other methods of qualification shall require acceptable justification and written permission from the Buyer before proceeding with the tests.

5.3.2 RIM Testing The input motion should be applied to each of the three mutually orthogonal axes individually.

Page 7 Revi r~ ~ :

• A - tat.

• .* ,pecirication No. lU4bb-J-8LU 15.4 Duration of Test Run The duration of each test run, i.e., each combination of acceleration amplitude and frequency pattern, shall be not less than 30 seconds, except that the sine sweep described in Section 5.2 shall be of a duration dictated by the sweep rate and frequency range.

5.5 Test Acceleration Level The required maximum test acceleration of the vibration table surface shall be determined from the curves shown in Figures 1 through 4, except for devices that will be qualified to the curve shown in Figure 3, and will be mounted in a panel. See Level C following.

5.6 Qualification Levels Any of the three levels of acceleration herein specified are acceptable:

5.6.1 Level A Conduct fragility tests to determine the maximum acceleration that the device can tolerate before malfunction or failure occurs. The Supplier shall assure that fragility level test amplitudes exceed the project acceleration levels of Figures 3 and 4, as applicable.

An acceptable method of fragility testing is to approach the level of Figure 1 RRS or the Figure 2 RIM incrementally in steps between 10 and 25 percent of the RRS or RIM. If the equipment failed at less than full level, the equipment would qualify for any RRS or RIM that the test data exceeded.

5.6.2 Level B Subject the device to the worst-case test acceleration that will qualify the device for most plant sites in the continental United States. See Figure 1 for nonline-mounted devices and Figure 2 for line-mounted devices.

5.6.2.1 Nonline-Mounted Devices Generic qualification of devices for use in'virtually all continental United States power plant sites is covered by Level B. The results of generic qualification shall demonstrate that the TRS exceeds (in amplitude) the envelope of worst-case RRS shown in Figure 1, which applies both to horizontal and vertical directions.

Page 8 Rev 1

Specification No. 10466-J-820 5.6.2.2 Line-Mounted Devices Generic qualification of devices for use in virtually all continental United States power plant sites is covered by Level B. The results of generic qualification shall demonstrate that the maximum qualification acceleration equals or exceeds the worst-case RIM shown in Figure 2, which applies to both the horizontal and vertical directions.

5.6.3 Level C Proof test the device to the particular test acceleration which is unique to its mounting location in the specific power plant structure. Level C reflects the reference SSE for the specific power plant site. The appropriate curves are attached as Figure 3 for nonline-mounted devices and Figure q for line-mounted devices. In cases where nonline-mounted devices are mounted in a control panel assembly, the qualification TRS must equal or exceed the amplitude values of Figure 3 multiplied by the vibration amplification factor (1.4) (Refer to J-821, Paragraphs 3.2.1 and 3.2.2).

5.7 Test Facility Limitations Figures 1 through 4 depict the dynamic characteristics of the device-mounting locations. it is recognized that the dynamic capability of actual vibration tables may be limited in some way.

The figures do not attempt to anticipate such limitations. The Bidder shall describe in his proposal the extent of any limitations.

5.8 Testing Requirements The devices shall be tested in all the physical orientations in which they can be used normally. If a standard mounting fixture will be used in the actual plant installation, that fixture shall be used during vibratory testing. Any additional attachments to the vibration table shall be dynamically rigid and shall not change the input motion at the device undergoing the test. If a special mounting fixture is required for actual installation, the dynamic properties of that fixture shall be conservative relative to the fixture used during the test.

1.0 INTRODUCTION

The purpose of this calculation is to generate In-Equipment Response Spectra for seismic qualification of replacement components inside the Main Steam and Feedwater Isolation Actuation System (MSFIS) cabinets.

The MSFIS cabinets are installed in the Main Control Room at elevation 2047'-6" at WCNOC.

Generation of In-Equipment Response Spectra For Seismic Qualification of MSFIS System Prepared By: Mohsin R Khan, PhD, P.E. Date: 1/09/07 Checked By: L. T. Nicholson Date: 1/09/07 2.0 INPUT The seismic qualification of the MSFIS cabinet was performed by shake table testing per Reference 1.

Resonance searches in the side-to-side, front-to-back, and in the vertical direction were performed to obtain the dynamic amplification factors at each input frequency. After the resonance search was completed, several bi-axial tests were performed in the side-to-side with vertical, and front-to-back with vertical direction of input motion. The testing demonstrated that the test response spectra conservatively enveloped the required response spectra.

Reference 2 documents the seismic qualification for the components installed inside the Engineered Safety Features Actuation System (ESFAS), Load Shedding and Emergency Load Sequencing System (LSFLS) and, MSFIS cabinets by shake table testing. The information provided in Reference 1 and 2 will be used to generate more realistic in-equipment response spectra for the seismic qualification of replacement components to be performed per Reference 3 and 4.

3.0 GENERATION OF IN-EQUIPMENT SPECTRA 3.1 WCNOC Floor Response Spectra WCNOC As-Built Response Spectra are provided in Calculation 10-19-F (Reference 5). Figures 3-1 to 3-3 show the As-Built 3% SSE for 3 SNUPPS site envelope Floor Response Spectra for the North South, East West and Vertical direction respectively. The digitized values of the response spectra are provided in Tables 3-1 to 3-3.

Generation of In-Equipment Response Spectra For Seismic Qualification of MSFIS System Prepared By: Mohsin R Khan, PhD, P.E. Date: 1/09/07 Checked By: L. T. Nicholson Date: 1/09/07 3.2 Amplification Factors In Reference 1, the MSFIS cabinet was tested to obtain the resonant frequencies and amplification factors, and for a conservative 4-site envelope SNUPPS input floor response spectra. Figure 3-4 shows the location of accelerometers that were instrumented in the cabinet. Figure 3-5 illustrates the corresponding channels that collected the data for the resonance searches. Figure 3-6 provides the output accelerations from the resonance search tests. As it can be seen that the highest response in the side-to-side direction is around 8 Hz. Therefore, the amplification factors around this frequency would be the greatest.

In Reference 2, the components to be mounted inside the MSFIS cabinet were separately tested using a generic response spectra. In this test report, the amplification factors for the floor response spectra to obtain in-equipment response spectra were based on the results of the bi-axial tests performed in Reference 1 and no resonance search data was used. These amplification factors used are as shown in column 5 of Figure 3-7. The amplification factor around 8 Hz is close to 1, thus indicating that there was no resonance around 8 Hz. Figure 3-8 shows a comparison of the envelope of the North-South and East-West floor response spectra times the square root of two and amplified floor response spectra using the factors in Figure 3-7. Figure 3-8 also shows a modified amplified floor spectra where the acceleration between 6 and 9 Hz is multiplied by an average amplification factor of 2.8 to account for the resonance frequency observed around 8 Hz. The modified amplified spectra is increased by 10% and plotted in Figure 3-9 and the corresponding digitized values are given in Table 3-4.

From Reference 1, there are no resonant frequencies in vertical direction and thus the floor spectra can be used.

Figure 3-10 is the vertical floor spectra from Section 3.1 increased by 10%. The corresponding digitized values are given in Table 3-5.

4.0 CONCLUSION

ARES has developed composite In-Equipment response spectra for the North-South and East-West direction.

The vertical spectra was developed separately, which is much lower than the North-South and East-West response spectra. All spectra are at 3% structural damping. The In-Equipment response spectra are provided in Figure 3-9 and 3-10 for the seismic qualification of components installed inside the MSFIS cabinets.
