SYSTEM OVERVIEW
1.1 INTRODUCTION
This document is based on WNA-GO-00075-WBT, Rev. 1, "WINCISE Signal Processing System Cabinet Operation & Maintenance Manual," (Reference 12). This version added applicable references and deleted references that were not being used. It was created to submit to the Nuclear Regulatory Commission for the Watts Bar Unit 2 NSSS Completion Project.
The components described in this manual cover only the Westinghouse In-core Information Surveillance
& Engineering (WINCISETM) Signal Processing System (SPS), which is a system that takes low-current signals from incore self-powered detectors (SPDs) and processes them before passing them to external host software. For background information, the remainder of this section provides an overview of how the SPS fits into WINCISE.
The WINCISE System uses signals from in-core SPDs distributed within the reactor core to obtain raw current signals. The current signals from the detectors, which represent the neutron flux activity at the detectors, are used with other reactor condition data to generate a three dimensional (3-D) indication of core power distribution on a continuous basis. WINCISE is an in-core flux monitoring application that utilizes the SPS.
The WINCISE System is an aftermarket application which replaces the plant's movable fission chamber detectors with new vanadium fixed in-core detectors to provide on-line core power information. There are 58 in-core instrument thimble assemblies (IITAs) for Watts Bar Unit 2. Each IITA contains five self-powered vanadium neutron detectors, sequentially increasing in length and axially distributed.
Each IITA contains six wires (five detector signals, one common sheath or collector signal), which are routed to one of two WINCISE SPS cabinets, both located inside of containment.
The IITA cables are divided into two independent subsystems or groups (Groups 1 and 2) to provide redundancy in core power measurements. The signals from the detectors in each IITA are routed to one of the two WINCISE SPS cabinets. The signals are divided between the two cabinets such that all detector signals associated with Group 1 are terminated in one WINCISE SPS cabinet and all the Group 2 signals are terminated in the other. Each cabinet contains the signal processing electronics (SPE) needed to process the analog signals from the SPDs and transmit the digitized data to the external host software. The SPE contains embedded firmware to convert the low-current analog signals from the detectors to multiplexed digitized data before transmitting it to the external host software residing on external application servers.
1.2 DESIGN FEATURES The WINCISE SPS incorporates the following design features:
Modular construction; [
]a.c.
Compatible with Rhodium or Vanadium self powered detectors.

]a' amplifier modules are seated between [
]a,, on each chassis. [
]a~c modules plug into the backplane through differently sized standard [
]a,c connectors.
Below the SPE chassis is the media converter assembly. The media converter assembly is where the digitized output is converted from serial to Ethernet, and transmitted out of the cabinet as single mode fiber Ethernet. The media converter assembly contains [

On the lower right side of the cabinet (from the front and shown in the LEFT view) is the DC distribution assembly. This is where the DC power from the power supply panel assembly is routed before it is distributed to the rest of the cabinet components.
On the upper right side of the cabinet (from the front and shown in the LEFT view) is the cabinet status interface panel. [
]a,c On the upper left side of the cabinet (from the front and shown in the RIGHT view) is the line filter panel assembly. AC power terminates into the cabinet at the line filter panel assembly through shielded conduit.
The line filter contains circuit breakers, surge suppressors, and filters to guard against transients in the AC line.
On the upper left side of the cabinet (from the front and shown in the RIGHT view), next to the line filter panel assembly, is the high temperature (hi-temp) cutout assembly. The hi-temp cutout is used to cut power to the cabinet when the internal ambient gets too high in order to protect the cabinet electronics from heat damage.

EQUIPMENT DESCRIPTION
2.1 INTRODUCTION
This section of the manual describes the equipment and modules that are part of the W[NCISE SPS. The major WLNCISE SPS components consist of the SPE, power supply equipment, media conversion equipment, a status interface panel, and a hi-temperature cutout. Westinghouse Drawing 10044E66 (Reference 10), "Watts Bar Unit 2 WLNCISE Cabinet Assembly," provides cabinet assembly details. See the Termination List in Appendix C of Reference 12 for detail on how equipment is wired together in the cabinet. See Appendix E of Reference 12 for a complete list of WINCISE SPS drawings.
2.2 DESCRIPTION
OF SYSTEM The WINCISE SPS begins with input current from detector assemblies and ends at the host software residing on external application servers which interface the signals to a display where reactor operators can monitor, analyze, and react to core data parameters.
Each cabinet receives input signals through bulk head connectors at the top of the cabinet.

The primary function of the IIS SPE chassis is to convert SPD input analog currents to digital values and transmit the values [
]axc. The secondary function of the IIS SPE chassis is to provide cabinet status information over the same [
]a,c The topmost chassis (11S01) is the master chassis, and will be explained further in this section.

]ac 2.2.1.2 IIS SPS Amplifier Module Assembly Figure 2-4, Figure 2-5, and Figure 2-6 show side, front, and isometric views of the IIS SPS amplifier module. The function of the IIS SPS amplifier module is to amplify and digitize low-level analog currents, and communicate the digital current values [
]a,c Each analog current is input to the IIS SPS amplifier module from the backplane card. As mentioned earlier, each IITA feeds input to [
]a c amplifier card [
]ac.
During normal operation, the current inputs are converted to voltages
]a,c. The voltages are input to an analog to digital (A/D) converter, which is regularly polled by a microcontroller on the amplifier module to provide a digital value which is proportional to the input current. [
]aC The use of isolation ensures that the inputs are electrically isolated from system ground.
One other mode of operation is available on the amplifier module. When requested by the datalink module [
]ac, the amplifier module will enter leakage test mode. In leakage test mode, an additional [
] is added to the current input path. The introduction of this resistance results in a change in the measured current due to the leakage of current in the cabling between the detector and the amplifier module. The change in measured current is used by the application servers to determine the current leakage and adjust the measured current to account for the leakage component.
Each amplifier module can have its calibration verified at the cabinet through known test signals that can be switched in through the front panel. [
]ac A 25 pin connector (TJ-1) located on the front of the amplifier card allows for an external test box to control the switching in of these signals. The test signals are switched in using a set of [
]aC relays; one per channel.

The function of the power supply panel assembly is to convert AC power from the cabinet input to I
]a,c power. Figure 2-10, Figure 2-11, and Figure 2-12 show front, rear, and side views of the power supply panel assembly. The power supply panel assembly is designed to take as input one single-phase AC power feed of 120 Vac at 60 Hz. Two pairs of power supplies provide redundant, auctioneered power output such that if one power supply fails, the second supply will be able to support the full power load of that pair. One pair of power supplies is rated to supply up to [
]a,c, and the other is rated to supply up to [
]ac. In the cabinet design, the [
]a,, power supplies provide power to the SPE chassis, and the
[
]a' power supplies provide power to the supportive electronics in the cabinet.

ja,c outputs of the master chassis datalink cards to [
]a'C and communicate with the external server over [

]a'c and the redundant master datalink utilizes the other [
]ac to communicate with the external servers.
WCAP-1 7458-NP July 2011 Revision 0
WESTINGHOUSE NON-PROPRIETARY CLASS 3 2-11 The input to the device servers is a [
]a (labeled [
]a,c),
which accepts [
]ac from one of the master chassis datalink cards. The output from one serial device server [
]flc is [
]a, and it connects to one of the [

The cabinet status interface assembly has two functions: provide a single termination location for cabinet status wiring and monitor temperature through use of an analog temperature sensor, which outputs a voltage proportional to the air temperature within the cabinet when supplied with power. Figure 2-15 and Figure 2-16 show front and side views of the cabinet status interface panel. All status signals input to the cabinet status interface and the temperature sensor output are sent to the datalink modules on the SPE chassis, where all analog signals are converted to digital values, and all status information is communicated to the external server.

WESTINGHOUSE NON-PROPRIETARY CLASS 3 2-13 2.2.5 High Temperature Cutout Assembly (Westinghouse Drawing 10042D45, Reference 7)
The function of the high temperature cutout is to shut off power to cabinet components when the temperature rises above [
1a,c to prevent equipment damage. Table 2-1 shows the maximum temperature ratings of each cabinet component. Figure 2-17 and Figure 2-18 show front and side views of the high temperature cutout assembly. The purpose of shutting off the power is to protect the cabinet electronics in the case of a loss of cooling. In the case of a high temperature, the temperature switch on the high temperature cutout closes, energizing the relay and opening the connection between the AC line filter panel and the power supply panel. Once the temperature has dropped sufficiently
[
] 1, the high temperature cutout can only be reset by cycling cabinet power. This can be done locally using the breaker on the power input line filter panel or remotely using a circuit breaker on the power feed to the cabinet.

The function of the line filter assembly is to protect the cabinet from faults on the power line, and to protect the power line from faults within the cabinet. Figure 2-19 shows the front view of the power input line filter assembly. The power first is connected through a circuit breaker to protect against overcurrent, then through a surge suppressor to protect against short duration overvoltage. The final component in the line filter assembly is a line filter, which is designed to limit the harmonics on the power line caused by the cabinet power supplies.

CAW-11-3218 AFFIDAVIT COMMONWEALTH OF PENNSYLVANIA:
ss COUNTY OF BUTLER:
Before me, the undersigned authority, personally appeared B. F. Maurer, who, being by me duly sworn according to law, deposes and says that he is authorized to execute this Affidavit on behalf of Westinghouse Electric Company LLC (Westinghouse), and that the averments of fact set forth in this Affidavit are true and correct to the best of his knowledge, information, and belief:
B. F. Maurer, Manager ABWR Licensing Sworn to and subscribed before me this 28th day of July 2011 ONotary Pbi COMMONWEALTH OF PENNSYLVANIA Notarial Seal Cynthia Olesky, Notary Public Manor Boro, Westmoreland County.
My Commission Expires July 16, 2014 Member. Pennsylvania Association of Notaries
2 CAW-1 1-3218 (1)
I am Manager, ABWR Licensing, in Nuclear Services, Westinghouse Electric Company LLC (Westinghouse), and as such, I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure in connection with nuclear power plant licensing and rule making proceedings, and am authorized to apply for its withholding on behalf of Westinghouse.
(2)
I am making this Affidavit in conformance with the provisions of 10 CFR Section 2.390 of the Commission's regulations and in conjunction with the Westinghouse Application for Withholding Proprietary Information from Public Disclosure accompanying this Affidavit.
(3)
I have personal knowledge of the criteria and procedures utilized by Westinghouse in designating information as a trade secret, privileged or as confidential commercial or financial information.
(4)
Pursuant to the provisions of paragraph (b)(4) of Section 2.390 of the Commission's regulations, the following is furnished for consideration by the Commission in determining whether the information sought to be withheld from public disclosure should be withheld.
(i)
The information sought to be withheld from public disclosure is owned and has been held in confidence by Westinghouse.
(ii)
The information is of a type customarily held in confidence by Westinghouse and not customarily disclosed to the public. Westinghouse has a rational basis for determining the types of information customarily held in confidence by it and, in that connection, utilizes a system to determine when and whether to hold certain types of information in confidence. The application of that system and the substance of that system constitutes Westinghouse policy and provides the rational basis required.
Under that system, information is held in confidence if it falls in one or more of several types, the release of which might result in the loss of an existing or potential competitive advantage, as follows:
(a)
The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of
3 CAW-11-3218 Westinghouse's competitors without license from Westinghouse constitutes a competitive economic advantage over other companies.
(b)
It consists of supporting data, including test data, relative to a process (or component, structure, tool, method, etc.), the application of which data secures a competitive economic advantage, e.g., by optimization or improved marketability.
(c)
Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing a similar product.
(d)
It reveals cost or price information, production capacities, budget levels, or commercial strategies of Westinghouse, its customers or suppliers.
(e)
It reveals aspects of past, present, or future Westinghouse or customer funded development plans and programs of potential commercial value to Westinghouse.
(f)
It contains patentable ideas, for which patent protection may be desirable.
There are sound policy reasons behind the Westinghouse system which include the following:
(a)
The use of such information by Westinghouse gives Westinghouse a competitive advantage over its competitors. It is, therefore, withheld from disclosure to protect the Westinghouse competitive position.
(b)
It is information that is marketable in many ways. The extent to which such information is available to competitors diminishes the Westinghouse ability to sell products and services involving the use of the information.
(c)
Use by our competitor would put Westinghouse at a competitive disadvantage by reducing his expenditure of resources at our expense.
4 CAW-1 1-3218 (d)
Each component of proprietary information pertinent to a particular competitive advantage is potentially as valuable as the total competitive advantage. If competitors acquire components of proprietary information, any one component may be the key to the entire puzzle, thereby depriving Westinghouse of a competitive advantage.
(e)
Unrestricted disclosure would jeopardize the position of prominence of Westinghouse in the world market, and thereby give a market advantage to the competition of those countries.
(f)
The Westinghouse capacity to invest corporate assets in research and development depends upon the success in obtaining and maintaining a competitive advantage.
(iii)
The information is being transmitted to the Commission in confidence and, under the provisions of 10 CFR Section 2.390; it is to be received in confidence by the Commission.
(iv)
The information sought to be protected is not available in public sources or available information has not been previously employed in the same original manner or method to the best of our knowledge and belief.
(v)
The proprietary information sought to be withheld in this submittal is that which is appropriately marked in WCAP-17458-P, Revision 0, "WINCISETM Signal Processing System Cabinet Operation & Maintenance Manual" (Proprietary), dated July 2011, for submittal to the Commission, being transmitted by Tennessee Valley Authority letter and Application for Withholding Proprietary Information from Public Disclosure, to the Document Control Desk. The proprietary information as submitted by Westinghouse is that associated with the Incore Instrument System (IIS) and may be used only for that purpose.
5 CAW-11-3218 This information is part of that which will enable Westinghouse to:
(a)
Assist the customer in providing technical licensing information to the NRC that is required for approval of the Watts Bar Nuclear Unit 2 US System.
Further this information has substantial commercial value as follows:
(a)
Westinghouse plans to sell the use of similar information to its customers for the purpose of licensing in-core instrumentation systems.
(b)
Its use by a competitor would improve his competitive position in the development and licensing of a similar product.
(c)
The information requested to be withheld reveals the distinguishing aspects of a design developed by Westinghouse.
Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of Westinghouse because it would enhance the ability of competitors to provide similar calculations, analysis and licensing defense services for commercial power reactors without commensurate expenses. Also, public disclosure of the information would enable others to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the information.
The development of the technology described in part by the information is the result of applying the results of many years of experience in an intensive Westinghouse effort and the expenditure of a considerable sum of money.
In order for competitors of Westinghouse to duplicate this information, similar technical programs would have to be performed and a significant manpower effort, having the requisite talent and experience, would have to be expended.
Further the deponent sayeth not.
