Subject:

Docket No. 50-482: Supplemental Information on Main Steam and Feedwater Isolation System Controls Modification Gentlemen: The Reference provided a license amendment request 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)." The Reference 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 March 21, 2007, Wolf Creek Nuclear Operating Corporation (WCNOC) received electronic mail from the Nuclear Regulatory Commission (NRC) Project Manager indicating that the Reference was lacking sufficient information to support the review of the application. On April 3, 2007, the NRC Project Manager provided by electronic mail, a generic list (table) of items that the Technical Branch believed was necessary for completion of the staff review of the application. During a telephone conference on April 3, 2007, WCNOC agreed to provide by April 4, 2007, if the information in the generic list was currently available and if not currently available when it would be available. On April 4, 2007, WCNOC provided by electronic mail a modified table that provided information regarding specific information identified by the NRC as being needed and the availability of the information. WCNOC provided the available information on April 9, 2007, and indicated that this information would be provided on the docket by May 4, 2007. The Enclosures provide, on the docket, the information provided on April 9, 2007. Enclosures IV, VII, IX, and XII contain proprietary information. P.O.

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 and Dedication Supplier (Qualification Seller). The Controls Seller is responsible for the selection, assembly, implementation testing, and implementation of the Replacement MSFIS System. The Qualification Seller is responsible for the Qualification and Dedication of the Replacement MSFIS System supplied by the Controls Seller. The Qualification Seller shall be a qualified IOCFR50 Appendix B vendor.

The Buyer or Buyer's consultant 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 Selleris 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 MSJVs 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.

Replacement of output relays and bases and supply of new surge suppressors. REV SPECIFICATION NUMBER J-105A(O) 2 Page 3

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

7.

Mounting hardware and wiring devices as necessary to mount the replacement components and interconnect themto 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. 3.0 ABBREVIATIONS AC All Close C Close / Closed DC Direct Current ESFAS Engineered Safety Features Actuation System FWIS Feedwater Isolation Signal KC Keep Closed KO Keep Open MFIV Main Feedwater Isolation Valve MSFIS Main Steam and Feedwater Isolation Actuation System MSIS Main Steam Isolation Signal MSIV Main Steam Isolation Valve 0 Open REV SPECIFICATION NUMBER J-105A(O'I 2 Page 4

2)

Status Outputs In addition to the actuation outputs, one status output shall be provided for each actuation train for each valve. This status output is shown in Appendix B. The MSFIS System status output will supply 125 Volt DC power to an input relay at the Status Panel if both of the following are true: a) 125 Volt DC power is available downstream of theindividual power supply fuses for solenoid MV5(6), and b) there is no test in progress in the MSFIS System logic. The output to the Status Panel shall be able to handle a 125VDC, <25mA load.

3)

Annunciator The MSFIS shall provide outputs to the plant Annunciator system as described in section 5.6.7. The annunciator outputs shall be able to handle a 125VDC, <25mA load.

4)

ESFAS Test Circuits The MSFIS shall provide one output for each actuation train for each valve to the ESFAS test circuitry, as described in section 5.2.6. These outputs shall be able to handle an 118VAC, <500mA load. REV SPECIFICATION NUMBER .1.105 A(O) 2 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 MVl, 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

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 place the CLOSE output state for all four valves for the respective switch, MSIV or MFIV. I REV SPECIFICATION NUMBER ,-105A(O) 1 2 Page 9

FORM APF-05-004-04, Rev. 0 The output state shall remain CLOSE for 60sec +/- Isec 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 for the particular valve based on the contact inputs from the SSPS slave relay, and 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 +/- lsec 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 MSFJS 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-105AOQ) 2 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:

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. BYPASS mode shall be entered automatically in the event of the Automatic Exception Detection circuitry, as described in 5.2.6 3) a, detecting an improper operation preventing the system to perform it's required safety function.

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 ve~rify that Class lB 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 pan-el, 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 iniformation 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

SSpecification No. 10466-J-8-1 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 attachmient is to specify qualification procedures and acceptance criteria that conform to IEEL Standard 344-1975, Recommended Practices for Seismic Qualifications of Class 1E 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 appliQations rather than to requalify the devices for each power plant project. Such a ltest program shall be based on a representative number of standard devices. An acceptable genezic 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 b]e 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. Page 2 Rev i -77:...

Specification No. 104L66-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.

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 344.. 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

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 Motion (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 1E 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 qualifyinq equipment by utilizing the response spectrum, the TRS is to be compared to the RRS.1"

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 Rev 0

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

4.

FUT.NCTIONAL REQUIREMENTS 4.1 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 malfunctione.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-1 Classification Devices that 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 the acceptance criteria specified in Section 14.2. 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 minimtunm 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 7

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

h.

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 plant. 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 lHz.

However, 1 to 33 t1z 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 0

SSpecification No. 10466.-J-820 Figure 1 is an RRS and corresponds, in acceleration and frequency 6:, 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 PRS unless written permission to deviate is granted by the Buyer. Line-mounted devices shall refer to Figure 2, which is the R11.i 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 RIJ. Testing with other wave form characteristics than those described in this paragraph may 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 RRS for nonline-' mounted devices or that the test table motion equals or exceeds the RII for line-mounted devices. Test motions other than random shall be in conformance with the criteria of IEEE-3 4 4, 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 .equipnient when the equipment is in its normal mounting position. Independent random inputs are preferred, and, if used, the test shall be performed 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 Rev.1

Specification No. '10466-J-820 .5.4 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-mnunted devices and Figure 2 for line-mounted devices. 5.6.2.1 Nonline-Mounted Devices Generic qualification of devices for use in"virtually all cpntinental 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. 10o46-J-uzu 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 4 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. Page 9 Rev 0

Specification Nd. 10466-J-821 SEISMIC QUALIFICATION REQUIRE'rENTS FOP CLASS IE CONTROL PNTEL ASIFTVBLIF. SCOPE 1.1 General This specification attachment establishes acceptable qualification methods and the requirements to verify that Class IE control panel assemblies can perform their safety-related functions during and following a safe sbutdown earthqua):e, SSE. Where possible, control panel assemblies shall be designed with sufficient dynamic rigidity (with no structural resonances below 33 Hz) to keep at a minimum any amplification of floor motion within the panel assembly. Where it is not possible or economical to achievesufficient

rigidity, the control panel assembly amplification factor shall be limited as described in the Structural Response Test Section, below.

All Class 1E devices used on the control.panel assemblies shall be qualified for this service. 1.2 Responsibilities The Buyer, Bechtel Power Corporation, will be responsible for defining the required response spectrum at each control panel assembly mounting location. The testinq 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 existing contractual agreements. The assurance of seismic qualification of the Class 1E devices shall be the responsibility of whoever purchases the devices - Bechtel Power Corporation, the control panel fabricator, or another entity. 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 snccifv qualification procedures and acceptance criteria that conform to IET-ET Standard 344-1075, Recommended Practices for Seismic Qualifications of Class 111 Equipment for iluclear. Power Cenerating Stations. Page 1 Rev 0

Specification No. 104f6-J-921 It shall he acceptable for the Supplier to perform comprehensive generic,* one-time qualification tests of standard control parel assembly structures. Then these standard structures can he adapted for specific control panel assemblies provided the structural elements can be shown to be sufficiently similar to the qualified, standard design. Alternatively, control panel assemblies may be qualified to the particular floor response spectra of a specific power plant. .1.4 Device Qualification Seismic qualification of Class 1E devices is covered by Specification Attachment 10466-J820. Alternatively, Class 1E devices and the control panel assembly may be qualified simultaneously by vibratory testing of the completed control panel assembly and monitorina the Class 1E devices while they are in their normal operating condition. 2.0 DEFINITIONS This section defines words in the context in which they are used in this specification. The portions in quotation marks were excerpted from IEEE Standard 344. Definitions of other terms used in this specification are given in IEEE Standard 344. 2.1 Control Panel Assembly An assembly consisting of a freestanding enclosure complete with all control and instrumentation devices and interconnecting wiring; the term, "control panel assembly," a-used herein shall include benchboards, vertical-front panels, consoles, and cabinets. 2.2 Class 1E Control Panel Asserbly A-control panel assembly that contains any Class 1E device. 2.3 Device An individual item of ec-uipment with specific operational functions. Examples are sensors, transmitters, controllers, bistables, indicators, recorders, relays, control switches, etc. Page 2 Rev 0

Specification rno. 10466-J-821 2.3.1 Class 1E Devices Devices which are in nuclear safety-related service and to which is applied "The safety classification of the electric equiprrment and systems that are essential to ewergency 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. 2.4 Floor Acceleration "The acceleration of a particular building floor (or ecuipment mounting) resulting from a given earthquake's motion. The maximum floor acceleration can be obtained from the floor response snectrum as the acceleration at high frequencies (in excess of 33 Hz), and is sometimes referred to as the zero period acceleration (ZPA)." 2.5 Response Spectrum The maximum response (usually acceleration, but possibly displace-ment or velocity) of a second-order mechanical system, consisting of a spring, a damper, and a unit mass and having a specified damping ratio, expressed as a function of natural frequency, to some input motion defined over a specific time interval. 2.6 Required Response Spectrum (RRS) "The response spectrum issued by the user or his agent as part of his specification for proof testing or artificially created to cover future applications. The RRS constitutes a requirement to be met." 2.7 Safe Shutdown Earthquake (SSF) "That earthquake which produces the maximum vibratory ground motion for which certain structures, svstems, 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 condition, 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 Requlations, Title 10, Part 100 (December 5, 1973)." Page 3 Rev i g-----VPT,-,.-

Specification No. 10466-J-821 2.8 Test Response Spectrum (TRS) "The response spectrum which is constructed using analysis, or derived 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." 3.0 QUALIFICATION PROCEDURrs Control panel assemblies may be qualified by an analytic method or by actual vibratory testing. In applications where a nonseismically classified panel and a Class 1E control panel assembly are to be adjacent physically, the Supplier shall account for this condition and shall analyze the dynamic interaction of the two panels. Consideration should be given to physical separation of the panels to preclude any dynamic interaction. 3.1 Qualification by Analytic Method An acceptable method is to design the control panel assemrbly as a dynamically rigid assembly without any resonance frer!uencies below 33 Hz. If the analysis of the panel structure and device-mounting surfaces confirms the dynamic rigidity of the assembly, the dynamic forces shall be considered to act throuch the assembly center of gravity and to be combined-with gravitational forces in a static-coefficients analysis. Alternatively, qualification by means of dynamic analysis mav be used for a nonrigid control panel assembly. In either case, at least one complete control panel assembly shall be subjected to a continuous sinusoidal sweep at a rate not greater than 2 octaves per minute over the frecuency range equal to or areater than that to which the equipment is to be qualified according to the procedures in =lEE-344, Section 6.1.3, 4 Exploratory Tests.. If such exploratory tests are made, the acceleration levels must be-at least 20 percent of the equipment design SSI, and the agency performing the analysis must certify that all critical resnonses of the equipment have been identified. The equipment shall be subjected at its resonant response frequencies, to full-level single-frequency tests to verify the mathematical model used in each control panel assembly analysis. Only the seismic qualification conditions in Sections 4.1, 4.3, 4.5, and 4.6, as applicable,, shall apply for qualification by this method. The test to verify the mathematical model used for the analysis shall be designed to verify the assembly resonant frequencies, pred*ominant mode shapes, and dampin'T factors and. may be performed at low acceleration levels. Page 4 Rev 0 !7,~...,.- T T 7 '

Specification No. 10 466-J-821 It is permissible to add structural elements to a control panel assembly to modify its response characteristics in order to achieve dynamic rigidity; however, the final analysis always shall reflect the assembly as-built state. The acceptance criteria for qualification by analysis are the-same as those for qualification by Structural Response Test, Paragraph 3.2.1. 3.2 Qualification by Test Method Control panel assemblies may be qualified by actual vibratory testing. 3.2.1 Structural Response Test An acceptable test method is to determine the dynamic response of the control panel assembly structure and the device-mounting surfaces by using a sufficient number Qf accelerometers attached at the location of the Class 1E devices. The vibratory testing shall be performed using either actual devices or simulated panel loads which duplicate the mass, stiffness, and volume of the actual devices and appropriate appurtenances, e.g., raceways, instrument tubing, and attachments, in order to simulate as closely as possible actual panel loadina conditions. In either case, all devices, both Class IE and non-Class 1E, shall be mounted on the control panel assembly under:test. The test freauency range and acceleration level shall be as specified in Section 4. The acceptance critera for this test are:

a.

That the maximum acceleration level at Class 1E device-mounting locations shall be less than 1.4 times the maximum base excitation acceleration.

b.

That there be no control panel assembly structural failure. C. That there be no structural deflection which can interfere with the safety-related function of Class 1E devices and 4 circuits. 3.2.2 Functional (Operability) Proof Test An alternate test method is to demonstrate the functional adeauacv of all Class 1E devices while the control panel assembly is undergoing vibratory excitation. Page 5 M 'Rev1 1~OV 01. A Wn., .;gj

Specification No.. 1066-J-821 For this test, all devices shall be mounted on the control panel-assembly, and all Class 1E devices shall be 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. The test frequency range and acceleration level shall be as specified in Section 4. The acceptance criteria for control panel assemblies are:

a.

That the maximum acceleration level at-Class 1E device-mounting locations shall be less than 1.4 times the maximum base excitation acceleration.

b.

That there be no control panel assembly structural failure which would inhibit or prevent performance of a safety-related function

c.

That there be no structural deflection which could interfere with the safety-related function of Class 1E devices and circuits. The acceptance criterion for qualification tests is that there be no Class 1E 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

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 detcrmined during vibratory excitation.

f.

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

g.

Loss of required function, e.g., ability to change state. Page 6 Rev 0 r-0-

Specification No. 10466-J-821 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. 4.0 SEISMIC QUALIFICATION CONDITIONS 4.1 Test Procedures Written test procedures shall be prepared for all tests and submitted to the Buyer. The test procedures 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 motion of the actual floor surface on which the control panel assembly will be mounted. Pr Equipment shall be subjected to the acceleration values described in Section 4.6. Vibratory tests should be conducted over the range of 1 to 33 Hz. The acceleration and frequency values refer 12. to the response of single-degree-of-freedom oscillators attached to the vibration table surface on which the test specimen shall be mounted. The three percent critical damping spectrum shall be used as the RRS unless written permission to deviate is granted by the Buyer. 4.2 Vibration Table Excitation (Wave Form) The preferred excitation shall be random-motion wave form. Testing with other wave-form characteristics (frecuency content) may be acceptable, depending on the RRS or assembly in nuestion. However, test wave forms other than random rotion shall be justified adequately for each control panel assembly being qualified. The wave-form characteristics of the proposqce test input motion shall be such that the TRS ecuals or exceeds the RRS. Test motions other than random shall be in conformance with the criteria of !=-344, Section 6.6, Test Methods. 4.3 Direction of Vibratory Motion The input motion shall be applied simultaneously to the vertical axis and to a horizontal axis parallel to the front surface of the equipment when the equinment is in its normal mounting position. Independent rancom inputs ate preferred, and, if

used, Page 7 Rev 2 fr

Specification No. 10466-J-821. the test stall be performed in two steps with the equipment rotated 90 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. 4.4 Duration of Test Run The duration of each test run, i.e., each-combination of acceleration amplitude and frequency pattern, shall he not less than 30 seconds. 4.5 Test Acceleration Level The required maximum qualification acceleration of the control panel assembly mounting surface shall be-determined from the RRS curve at a frequency greater than 33 Hz, i.e., at the ZPA level shown either in Figure 1 or 2. 4.6 Qualification Levels Either of the two levels of acceleration herein specified are acceptable: 4.6.1 Level A Subject the control panel assembly to the worst-case test acceleration that will qualify the panel for the most plant sites in the continental United States. See Figure 1. Ceneric qualification of control panel assemblies for use in virtually all continental United States power plant sites is covered by Level A. 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 to both horizontal and vertical directions. 4.6.2 Level B Subject the control panel asserbly to an input rotion which will result in a TPS ecual to or greater than the RlS for its rounting location in the specific power plant. Level B reflects the reference SSE for the snecific powcr plant site and Is shown in Figure 2. 4.7 Test Facility Limitations The RRS, either from Fiqure 1 or from Fiqure 2, dep.icts the dynamic characteristics of the panel mounting locations. It is .2 %' Page 8 Rev 2 77*77 7

Specification No. 10466-J-821 recognized that the dynamic capability of actual vibration tables may be limited in some way. The,RRS does not attempt to anticipate such limitations. The.Bidder shall describe the extent of any limitations in his proposal. 4.8 Testing Requirements For vibratory testing, the control panel assembly shall be secured to the vibration table (or other mounting surface) with hardware similar to that which will be used in the actual plant installation. The Seller shall insure that the motion at the support points of the assembly (the points at which the assembly is supported when properly mounted on the floor) meets the requirements stated elsewhere in this Specification. The mount-ing hardware and the test table motion shall be designed accordingly. 5.0 DOCUMENTATION 5.1 Submittals The Bidder shall provide with his proposal the proposed qualification procedure delineating the steps to achieve qualification. Prior to fabrication, the Supplier shall Submit his qualification procedure for Buyer approval. Sufficient detail shall be used to demonstrate adequacy of the selected method (see Section 5.2).
