AW-94-622 (1) I am Manager, Advanced Plant Safety and Licensing, in the Advanced Technology Business Area, of the Westinghouse Electric Corporation 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 rulemaking proceedings, and am authorized to apply for its withholding on behalf of the Westinghouse Energy Systems Business Unit.
(2) I am making this Affidavit in conformance with the provisions of 10CFR Section 2.790 of the Commission's regulations and in conjunction with the Westinghouse application for withholding accompanying this Affidavit.
(3) I have personal knowledge of the criteria and procedures utilized by the Westinghouse Energy Systems Business Unit 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 2.790 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 ratiot.al 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:
16A9A l
I AW-94-622 )
(a) The information reveals the distinguishing aspects of a process (or component, ;
1 structure, tool, method, etc.) where prevention of its use by any of l 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.
(c) 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 i following:
(a) The use of such information by Westinghouse gives Westinghouse a j competitive advantage over its competitors. It is, therefore, withheld from disclosure to protect the Westinghouse competitive position. ;
I It is information which is marketable in many ways. The extent to which such l (b) ;
1 information is available to competitors diminishes the Westinghouse ability to sell products and services involving the use of the information.
16P9A
AW-94-622 (c) Use by our competitor would put Westinghouse at a competitive disadvantage by reducing his expenditure of resources at our expense.
(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 10CFR Section 2.790, 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.
1 (v) Enclosed is letter NTD-NRC-94-4114, May 17,1994, being transmitted by Westinghouse Electric Corporation (_W) letter and Application for Withholding Proprietary Information from Public Disclosure, N. J. Liparulo (E, to Mr. R. W. Borchardt, Office of NRR. The proprietary infonnation as submitted for use by Westinghouse Electric Corporation is in response to questions concerning the AP600 plant and the associated design certification application and is expected to be applicable in other licensee submittals in response to certain NRC requirements for justification of licensing advanced nuclear power plant designs.
190A

AW-94-622 l l
This information is part of that which will enable Westinghouse to:
l (a) Demonstrate the design and safety of the AP600 Passive Safety Systems.
(b) Establish applicable verification testing methods.
(c) Design Advanced Nuclear Power Plants that meet NRC requirements.
(d) Establish technical and licensing approaches for the AP600 that will ultimately result in a certified design.
(e) Assist customers in obtaining NRC approval for future plants.
Further this information has substantial commercial value as follows:
(a) Westinghouse plans to sell the use of similar information to its customers for purposes of meeting NRC requirements for advanced plant licenses.
(b) Westinghouse can sell support and defense of the technology to its customers in the licensing process.
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 advanced nuclear power designs 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 for developing analytical methods and receiving NRC approval for those methods.

Question 952,44 Provide the following information to assist the staff in developing TRAC AP600 plant models for large break f loss-of-coolant accident analysis:
- a. Provide the reactivity coefficients for this core design. This should include the sensitivity to reactor coolant temperature, fuel rod temperature, void fraction (two-phase density change), and boron concentration.
- b. Provide the control rod reactivity insertion as a function of time after scram.
- c. Provide check valve characteristics, specifically the check valves associated with the core makeup tank and accumulator injection and core makeup tank pressure balance line from pressurizer (pressure differentials required for opening and closing, rate of opening and closing, and full-open area).
Response
- a. The reactivity feedback model used in the ,WCOBRA/ TRAC code is provided below:
The total reactivity TRIPL, is calculated as a function of time, t, as:
TRIPL=p;FRHO(WDENS, PPM,FRHOBU)+DOP(T p)+ RODS +RHOZ where: p., = initial reactivity (input as 0.0)
FRHO = rextivity (defined as inAk/kJ specified as a polynomial function of the water density, WDENS, boron concentration, PPM, and average bumup, FRHOBU k,, is k at Pw20 = 0.7 gm/cm' DOP,,,, = Doppler feedback as a function of Tw, the average fuel temperature (*F) and the input multiplier (FDOP), which is input as 1.00, (4,C.)
L _
RODS = the control rod contribution, RHOZ = bias calculated at t=0 such that TRIPL = p.,
The functiorit! form of FRHO is given in Table 1. The coefficients were generated to fit the multiplication factor prediction for 17x17 V5H fuel. Units used in the polynomial fit are density (gm/cm'), boron concentration (ppm), burnup (MWD /MTU). At t=0.0, the code calculates the value of FRHOBU such that:
OFRIIO(WDENS , PPM,.0,FRHOBU) = 0.0 d(WDEN5) 1 l

A sletailed noding diagram and model description of the COBRA vessel nodalization in the AP600
'l WCOBRATIRAC model is presented in Appendix 15C, Proprietary Volume 3 of the SSAR.
Figure 1 is a detailed nodalization for the one-dimensional components in the AP600 WCOBRA/ TRAC model.
The AP600 model consists of a number of PIPE, VALVE, TEE and STGEN components connected via junctions in a network with a reactor VESSEL component. Note that the break location for the cold leg breaks is in one of the cold legs connected to a core makeup tank; the pressure balance line is assumed to remain connected on I

[ Note: The CMT-Pressurtzer balance line has been deleted from the current AP600 design] Further model description of the one-dimensional TRAC components is available in Appendix 15C in Proprietary Volume 3 of the SSAR.
The following information is provided in response to the specific requests for steady-state WCOBRA/ TRAC values:
- a. The containment H1 pressure setpoint is attained at one second after the large break LOCA event initiates, generating an "S" signal which leads to all subsequent system actuations.
For simplicity, because this signal is so fast and maintaining a bot secondary side is conservative for large break LOCA events, steam generator feedwater and steam lines are isolated at time zero, and startup feedwater is not modeled. A 1.2 second delay is assumed in core makeup tank outlet valve opening, so the CMT flow paths are assumed to begin to open at 2.2 seconds of the transient. The PRHR heat exchanger is not actuated in the transient. [ Note: In the current AP600 design, the PRHR heat exchanger is actuated on an "S" signal) Control rod insertion into the core is not modeled, so the core shuts down due to other negative reactivity insertions, particularly core voiding. The automatic reactor coolant pump trip occurs 17.2 seconds after the break initiation.
l b. Axial power profiles for the bot rod (Rod No.1), hot assembly average rod (Rod No.2) and core average power rods in open hole and guide tube locations (Rods No. 3 and 4) are provided in Appendtx 15C. Note that the rod power level in the guide tube channel 26 (Rod No.4) and open bole channel 25 (Rod No.3) are
, set to l 'f") times the core average channel power, while the peripheral channel 24 rod (Rod No.5) l power is [ l'") tunes the core average power rod.

Based on 102% of licensed core power (1933 MWt*l.02) operation, the maximum linear power generation rate of each rod (in kW/ft) equals [ . ]" kW/ft for the bot rod, [ f"> kW/ft for the bot assembly rod,: I"> kW/ft for the open bole and guide tube region fuel rods, and [ f") kW/ft for the peripheral rod.
- d. Primary coolant mass flow equals 20484 lbm/second in all loops combined.
- e. The bot leg and cold leg temperatures at the above total mass flow and 102% power equal 600.87 and 529.9'F in components 2/9 and 5/6/12/13, respectively.
- f. The feedwater flow is 3964 lbrn/second at a temperature of 4397.
- g. The steam generator exit pressure and temperature are 778.7 psia and 515.17 respectively.
, h. The core mass flow at the entrance of each channelis [ f") lbm/second in the penpberal channel, l [ 7") Ibm /second in the open boles channel, [ f") Ibm /second in the guide tube channel, and
