Containment and Accident Dose Assessment Section (SPSB-C)

RAI SPSB-C-32 Please provide input to the computer calculation (data in ASCII format) of the minimum containment accident pressure used for ECCS pump NPSH calculations for the double ended guillotine break of a recirculation line. Please verify that the input is consistent with the VYNPS emergency operating procedures. In addition, provide a schematic of containment with dimensions and ECCS schematic for this analysis. The input parameters needed are included in Attachment 1. [Attachment 1 is not repeated here.]

Response to RAI SPSB-C-32 Table SPSB-C-32-1 contains inputs used for the M3CPT/LAMB DBA-LOCA short-term analyses used to determine the peak DBA-LOCA drywell pressure. Table SPSB-C-32-1 also provides the inputs used for the DBA-LOCA short-term (600 second) and long-term (10 day) SHEX analyses used to calculate the containment response for NPSH evaluations. These inputs are consistent with the VYNPS emergency operating procedures.

Table SPSB-C-32-2A provides the core shutdown power used in the M3CPT/LAMB DBA-LOCA analyses for peak drywell pressure. Table SPSB-C-32-2B provides the core shutdown power used in the SHEX containment analyses. The values shown are normalized to the initial reactor power. The core shutdown power used in the M3CPT/LAMB calculation is that used for the LAMB break flow calculations which are performed in accordance with 10CRF50 Appendix K. The core shutdown power used in the LAMB break flow calculations includes fission power, fuel relaxation energy and decay heat based on the ANS 5-1971 decay heat model + 20 %. The shutdown power used in the SHEX analyses include fission power, fuel relaxation energy, metal-water reaction and decay heat based on ANS 5.1-1979 + 2 sigma with additional actinides and reactive products per SIL 636 Revision 1. The containment codes calculate the core shutdown power at each time step by multiplying the initial reactor power by the normalized core shutdown power obtained by interpolation of the tabular values. The initial core thermal power used in the analysis is assumed to be 2%higher than the rated core thermal power per Reg. Guide 1.49 (see response to RAI SPSB-C-4). For information, the core power calculated by the SHEX code at each time step (in Btu/sec) using Table SPSB-C-32-2B has been provided in Tables SPSB-C-32-5 and SPSB-C 6 (see Column labeled mCore Thermal Power").

Tables SPSB-C-32-3A and SPSB-C-32-3B provide ECCS and RHR pump heat vs. time for the SHEX short-term (600 second) and long-term (10 day runs) analyses.

Table SPSB-C-32-4 (M3CPT for peak drywell pressure), Table SPSB-C-32-5 (SHEX 600 second analysis for NPSH) and Table SPSB-C-32-6 (SHEX 10 day analysis for

Attachment 2 to BVY 04081 Docket No. 50-271 Page 3 of 123 NON-PROPRIETARY INFORMATION NPSH) provide time depended data requested by the RAI and referred to in Table SPSB-C-32-1 except for the data in Tables SPSB-C-32-2A and SPSB-C-32-2B which provide the normalized core shutdown curves. The data provided in Tables SPSB-C 4, SPSB-C-32-5 and SPSB-C-32-6 are obtained from the computer run output.

Figure SPSB-C-32-1 shows a schematic of the SHEX containment model.

Attachment 2 to BVY 04-081 Docket No. 50-271 Page 12 of 123 NON-PROPRIETARY INFORMATION Notes for Table SPSB-C-32-1:

(1) The break area shown for the LAMB analysis corresponds to the sum of the two sides of the broken recirculation suction line pipe at the break location. Note that shortly after the DBA-LOCA occurs, the LAMB break flow is limited by the choked flow which exists at the locations with minimum flow area upstream of the break.

The break area shown for the SHEX analysis is the sum of the minimum flow area upstream of the vessel side of the break (vessel safe end nozzle) and minimum flow area upstream of the pipe side of the break get pump nozzles).

(2) The RPV water level shown corresponds to the water level outside the core shroud. This value is used to calculate the liquid volumes within the LAMB vessel model and also to calculate the liquid volume in the VYNPS SHEX vessel model.

(3) The containment geometry parameters given for the M3CPT analyses correspond to conditions associated with the Technical Specification Suppression pool High Water Level (TS-HWL). The values given for the SHEX analyses correspond to conditions associated with the Technical Specification Suppression pool Low Water Level (TS-LWL).

(4) Not used.

(5) ((

(6) The break flow rate shown for the M3CPT/LAMB analysis for peak drywell pressure is calculated by the LAMB code based on the Moody SLIP critical break flow model. The values to 20 seconds have been provided which covers the time period past the time of the peak drywell pressure.

(7) The break flow for the "short-term" (600 second) SHEX analyses for evaluating NPSH includes two components. These components include; 1) break flow to the drywell from the vessel 2) direct LPCI break flow to the drywell which originates at the suppression pool.

The first component is the vessel break flow. The vessel break flow to the drywell is calculated using conditions in the vessel and the break area. The break flow rate for this component has an enthalpy corresponding to enthalpy of the vessel liquid.

See Table SPSB-C-32-5 for time varying vessel break flow data. The data in the columns labeled: "Vessel Liquid Break Flow Rate,' "Vessel Liquid Break Enthalpy,"

'Vessel Vapor Break Flow Rate," and WVessel Vapor Break Enthalpy' provide time histories of the vessel break flow and enthalpy.

The second component is the direct LPCI flow to the drywell. For this analysis it is assumed that 2 LPCI pumps inject into the broken recirculation loop. The LPCI

Attachment 2 to BVY 04-081 Docket No. 50-271 Page 13 of 123 NON-PROPRIETARY INFORMATION flow to the broken loop is assumed to flow directly to the drywell. This break flow has an enthalpy corresponding to the enthalpy of the suppression pool water (plus additional energy added by the LPCI pumps). The LPCI break flow rate equals the LPCI pump flow rate into the broken recirculation loop. Table SPSB-C-32-5 contains the LPCI break flow data. The LPCI break flow rate and break flow enthalpy is provided by the data in the columns labeled: "Direct LPCI Break Flow to Drywell" and "Enthalpy of Direct LPCI Break Flow to Drywell."

(8) The break flow for the "long-term" (10 day) SHEX analyses for evaluating NPSH includes only includes break flow to the drywell from the vessel. It is assumed for this analysis that all LPCI flow is injected to the vessel. See Table SPSB-C-32-6 for time varying vessel break flow data for this analysis. The data in the columns labeled: "Vessel Liquid Break Flow Rate," WVessel Liquid Break Enthalpy," "Vessel Vapor Break Flow Rate," and "Vessel Vapor Break Enthalpy" provide time histories of the vessel break flow and enthalpy.

(9) Note, the ECCS flow rates shown In Tables SPSB-C-32-5 and SPSB-C-32-6 (column labeled "ECCS flow to RPV") are the combined LPCI plus CS flow to the vessel. The flow enthalpy (Column labeled "ECCS flow enthalpy from suppression pool") is the enthalpy of the flow from the suppression pool not including the energy added by the pump heat.

(10) Note the containment spray flow enthalpy in Table SPSB-C-32-6 (Column labeled "Drywell and Wetwell Spray Enthalpy") is the enthalpy of the flow into the drywell and wetwell airspace and includes the RHR pump heat.

(11) The heat removal rate is calculated in SHEX with the following relationship:

Q = K x(T 1,-Tw) Btu/sec Where:

Q = Rate of heat removal per heat exchanger (Btu/sec)

T= RHR shell side inlet temperature (= suppression pool temperature)

T= Service water inlet temperature (12) The Moody Slip critical break flow model is used for the LAMB break flow calculations which are subsequently input to M3CPT peak drywell pressure calculation. The Moody Slip critical break flow is the same as used in the Appendix K ECCS/LOCA analyses and is conservative relative to the HEM model. The SHEX analyses use the HEM critical break flow model which is consistent with the critical break flow model identified for use during the Mark I Long-term Containment Program (NEDO-21888, NUREG-0661). Additionally, the key parameters obtained from the long-term containment response analysis (e.g., peak suppression pool temperature) occur well after the end of the vessel blowdown.

)) The suppression pool temperature at the time the long-term wetwell pressure falls to 14.7 psia is 143.50F.

Figures SPSB-C-33-5 and SPSB-C-33-6 show suppression pool water level response for the short-term and long-term post-LOCA, respectively. The SHEX suppression pool volume was converted to an equivalent level using VYNPS suppression pool geometric data. The NPSH calculation was not based on a time-dependent level. Short-term NPSH was determined at 600 seconds using a level of 11.93 ft. The SHEX equivalent

Attachment 2 to BVY 04-081 Docket No. 50-271 Page 82 of 123 NON-PROPRIETARY INFORMATION level is 12.24 ft. Long-term NPSH was determined using a level of 12.03 ft. The SHEX equivalent at the peak suppression pool temperature was 12.27 ft. The levels used for the NPSH calculation are based on the current licensing basis.

(2) The information sought to be withheld is contained in Attachment 2 to GE letter GE-VYNPS-AEP-355, Michael Dick (GE) to Craig Nichols (ENOI), VYNPS Extended Power Uprate - Response to NRC Request for Additional Information, Proprietary and Non-ProprietaryVersions, dated August 6, 2004. The Attachment 2 proprietary information, GE Responses to NRC RAIs (SPSB-C-32 and 33), is delineated by a double underline inside double square brackets. In each case, the superscript notation( 1 refers to Paragraph (3) of this affidavit, which provides the basis for the proprietary determination.

(3) In making this application for withholding of proprietary information of which it is the owner, GE relies upon the exemption from disclosure set forth in the Freedom of Information Act ("FOIA"), 5 USC Sec. 552(b)(4), and the Trade Secrets Act, 18 USC Sec. 1905, and NRC regulations 10 CFR 9.17(a)(4), and 2.790(a)(4) for "trade secrets" (Exemption 4). The material for which exemption from disclosure is here sought also qualify under the narrower definition of "trade secret", within the meanings assigned to those terms for purposes of FOIA Exemption 4 in, respectively, Critical Mass Energv Project v. Nuclear Repulatorv Commission. 975F2d871 (DC Cir. 1992), and Public Citizen Health Research Group v. FDA, 704F2dl280 (DC Cir. 1983).

(4) Some examples of categories of information which fit into the definition of proprietary information are:

a. Information that discloses a process, method, or apparatus, including supporting data and analyses, where prevention of its use by General Electric's competitors without license from General Electric constitutes a competitive economic advantage over other companies;
b. Information which, if used 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 of a similar product;
c. Information which reveals aspects of past, present, or future General Electric customer-funded development plans and programs, resulting in potential products to General Electric;
d. Information which discloses patentable subject matter for which it maybe desirable to obtain patent protection.

The information sought to be withheld is considered to be proprietary for the reasons set forth in paragraphs (4)a., and (4)b, above.

(5) To address 10 CFR 2.790 (b) (4), the information sought to be withheld is being submitted to NRC in confidence. The information is of a sort customarily held in confidence by GE, and is in fact so held. The information sought to be withheld has, to the best of my knowledge and belief, consistently been held in confidence by GE, no public disclosure has been made, and it is not available in public sources. All disclosures to third parties including any required transmittals to NRC, have been made, or must be made, pursuant to regulatory provisions or proprietary agreements which provide for maintenance of the information in confidence. Its initial designation as proprietary information, and the subsequent steps taken to prevent its unauthorized disclosure, are as set forth in paragraphs (6) and (7) following.

(6) Initial approval of proprietary treatment of a document is made by the manager of the originating component, the person most likely to be acquainted with the value and sensitivity of the information in relation to industry knowledge. Access to such documents within GE is limited on a "need to know" basis.

(7) The procedure for approval of external release of such a document typically requires review by the staff manager, project manager, principal scientist or other equivalent authority, by the manager of the cognizant marketing function (or his delegate), and by the Legal Operation, for technical content, competitive effect, and determination of the accuracy of the proprietary designation. Disclosures outside GE are limited to regulatory bodies, customers, and potential customers, and their agents, suppliers, and licensees, and others with a legitimate need for the information, and then only in accordance with appropriate regulatory provisions or proprietary agreements.

(8) The information identified in paragraph (2), above, is classified as proprietary because it contains detailed information in support of NEDC-33090P, Safety Analysis Report for Vermont Yankee Nuclear Power Station Constant Pressure Power Uprate, Class m (GE Proprietary Information), Revision 0, dated September 2003, which was submitted to the NRC. This power uprate report contains detailed results and conclusions from evaluations of the safety-significant changes necessary to demonstrate the regulatory acceptability for the power uprate of a GE BWR, utilizing analytical models, methods and processes, including computer codes, which GE has developed, obtained NRC approval of and applied to perform evaluations of the transient and accident events in the GE Boiling Water Reactor

('BWR"). The development and approval of these system, component, and thermal hydraulic models and computer codes was achieved at a significant cost to GE, on the order of several million dollars.

The development of the evaluation process along with the interpretation and application of the analytical results is derived from the extensive experience database that constitutes a major GE asset.

(9) Public disclosure of the information sought to be withheld is likely to cause substantial harm to GE's competitive position and foreclose or reduce the availability of profit-making opportunities. The information is part of GE's comprehensive BWR safety and technology base, and its commercial value extends beyond the original development cost. The value of the technology base goes beyond the extensive physical database and analytical methodology and includes development of the expertise to determine and apply the JFK-08-06-04-AFAff 355.doc Affidavit Page 2

appropriate evaluation process. In addition, the technology base includes the value derived from providing analyses done with NRC-approved methods.

The research, development, engineering, analytical and NRC review costs comprise a substantial investment of time and money by GE.

The precise value of the expertise to devise an evaluation process and apply the correct analytical methodology is difficult to quantify, but it clearly is substantial.

GE's competitive advantage will be lost if its competitors are able to use the results of the GE experience to normalize or verify their own process or if they are able to claim an equivalent understanding by demonstrating that they can arrive at the same or similar conclusions.

The value of this information to GE would be lost if the information were disclosed to the public. Making such information available to competitors without their having been required to undertake a similar expenditure of resources would unfairly provide competitors with a windfall, and deprive GE of the opportunity to exercise its competitive advantage to seek an adequate return on its large investment in developing these very valuable analytical tools.

I declare under penalty of penury that the foregoing affidavit and the matters stated therein are true and correct to the best of my knowledge, information, and belief Executed on this J Iday of OVI D 2004.
