AW-96-1017 1

(1)

I am Manager, Advanced Plant Safety And Licensing, in the Advanced Technology Businesc 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 j

Energy Systems Business Unit.

i l

(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.

j (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, j

i (i)

The information sought to be withheld from public disclosure is owned and has been held in confidence by Westinghouse.

I (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 l

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:

2974A

AW-96-1027 (a)

The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of 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 i

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 which 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.

2974A

AW-96-1027 (c)

Use by our competitor would put Westinghouse at a competitive disadvantage by reducing his expenditure of resources at our expense.

(d)

Each comp 3nent 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 i

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.

(v)

Enclosed is Letter NSD-NRC-96-4864, October 28,1996 being transmitted by Westinghouse Electric Corporation (E) letter and Application for Withholding Proprietary Information from Public Disclosure, Brian A. McIntyre (E), to Mr. T. R. Quay, Office of NRR. The proprietary information 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.

I l

l mu t

l

AW-96-1027 This information is part of that which will enable Westinghouse to:

(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.

Attachment - Description of_ pH Adjustment Analysis Cases

{

The following discusses two cases which bound the post accident contairunent water pH adjustment of I

the AP600. These cases assume the same release of radioactivity from the RCS during the same time

]

period. The differences between these cases bound the pH adjustment perfonnance and radioactivity release from the AP600. It is expected that case I will result in the largest 2 hr offsite dose. Case 2

{

is expected to result in a larger 30 day offsite dose and control room dose.

Case 1 Challenge to pH Adjustment in Containment j

. Accident - 2" CL LOCA System Operation -

ADS stages 1/2/3 fail, all stage 4 work Two CMT inject Two Accumulatorinject

- IRW3T doesn't inject (causes core damage)

IRWST dump to containment works (both lines)

IRWST gutter doesn't work CVS BAT is injected Comments - All of the activity released from the RCS initially enters the containment atmosphere.

It should be assumed that some water circulates from the containment into / through the IRWST. This assumption results in the largest challenge to the pH in the contamment by mixing in the borated water in the bottom of the IRWST.

Case 2 Challenge to pH A4ustment in IRWST Accident - Spurious ADS (stage 1)

' System Operation -

ADS stages 1/2/3 all work, all stage 4 fail Two Chn inject Two Accumulatorinject IRWST doesn't inject (causes core damage)

IRWST dump to containment works (both lines)

IRWST gutter works CVS BAT is injected Comments - All of the activity released fmm the RCS initially enters the IRWST through the ADS spargers under water. "Ihe IRWST dump is assumed to be initiated just as activity release from RCS is completed. This case will result in water in the bottom of the IRWE that is not mixed with the containment water & TSP (no recirculation should be assumed as was done in case 1). As a result its pH will remain low.

Note that the IRWST has vents to the contamment that open under tank pressurization and close when vent flow stops. Gravity operated louvers close the vents. 'Ihe vent area is about 5% of the IRWST roof surface area. As a result, after the blowdown of the RCS and the subsequent release of activity, the vents are expected to close.-

However, some exchange of IRWE air space with the containment atmosphere should be assumed due to leakage. Sensitivity studies may be required to determine the importance of this assumption.

FnX to Diane Jackson at NRC This is to amplify our " doneness" for section 3.9 of the SSAR and DSER.

Revision 9 (August; 1996) of the SSAR provided our last planned revision of section 3.9 to reflect design changes. This chapter will be changed only if an error is found or if required by NRC. The Open Item tracking system indicates that 97 of the 111 items associated with section 3.9 show "(W) Status" of

" Closed". Of the remaining 14 items 5 are awaiting Revision 10 of the SSAR and are tracked as " Resolved, SSARREV" items. Two items are associated l

with the Chapter 14 and are being tracked with other Chapter 14 related open items. The remaining 7 items require dialog with NRC and closure. The

"(NRC) Status" for the 111 items associated with section 3.9 shows 66 that are

" Resolved" or " Closed." Westinghouse knows of no further submittal requirements for 38 of the section 3.9 items which do not indicate " Resolved" or " Closed." As indicated on the schedule provided to NRC on October 15, 1996, it is our intent to supply NRC with all information necessary for it to complete the section 3.9 portion of the FSER by December 12,1996. We request that the NRC understand that Westinghouse is not expecting to submit any additional revisions or information for section 3.9 except for the 7 outstanding items identified above. We should have a teleconference definitively scheduled to resolve any remaining NRC concern.

Secondary Coolant System Leakage 3.7.8 B.3.7 PLANT SYSTEMS B 3.7.8 Secondary Coolant System Leakage BASES BACKGROUND Detection of leaks in steam generator (SG) secondary side piping and nozzles is necessary to ensure that the leak-before-break (LBB) pipe service conditions are met for the lines to which LBB applies.

These conditions apply only to the main steam and main feedwater lines which are inside containment.

By limiting operation following the detection of leaks associated with the postulated. leakage flaw (crack) size, pipe rupture is precluded.

Flaws smaller than the critical size normally only increase in size due to pressure i

or temperature transient cycles.

Flaws larger than the critical size are considered unstable and may increase in size due to a constant applied stress (i.e., pressure load).

Because pipe rupture is precluded, the equipment qualification design bases for equipment in the LBB pipe local area do not include conditions associated with pipe rupture. The primary advantage of this approach is that for, these lines, the pipe restraints are not designed to withstand forces and displacements associated with a pipe rupture (Ref. 1).

~

j This design approach requires that small pressure boundary leaks be detected and if not isolatable, action be taken to shutdown the plant.

Detection of leaks in excess of 0.5 gpa is necessary to preclude pipe rupture in MODES 1 through 4

.due to a safe shutdown earthquake (SSE). Therefore, pressure boundary leaks through cracks must be detected and action taken to isolate the leakage.

Leakage past gaskets and seals are not associated with conditions leading to pipe rupture and, therefore, are not considered to be pressure boundary leakage.

The same leak detection instrumentation, required to be OPERABLE by LCO 3.4.10, "RCS Leakage Detection Instrumentation," in MODES 1 through 4 for detection of reactor coolant system (RCS) leakage, is used for detection of secondary coolant system leakage in containment.

Evaluation of potential secondary coolant system leaks in excess of 5.0 gpm is required.

Additional instrumentation is available for evaluation of these leaks and is discussed in SSAR Section 5.2.5 (Ref. 2).

Secondary Coolant System Leakage 3.7.8 l

l BASES (continued) i APPLICABLE The limit on leakage ensures that conditions leading to pipe i

SAFETY ANALYSES rupture are detected and the event is avoided, thus reducing the probability of a secondary coolant system break inside containment.

Early detection of leakage permits operators i

to take action to limit the likelihood and consequences of l

postulated events.

Piping established by analysis to be LBB will not rupture, provided the critical flaw size is not exceeded. The leakage limit is conservatively selected to correspond to a leakage crack size that is detectable, structurally stable under seismic loads, and permits sufficient time for operator corrective action to preclude pipe rupture. The size of the leakage crack is established such that the

. expected leakage is 10 times the minimum leak detection capability for that location (Ref.1).

Limiting pressure boundary leaks in LBB piping permits elimination of local dynamic effects of postulated pipe ruptures from the equipment qualification design bases for essential structures, systems and components.

Local dynamic effects include; pipe whip, jet impingement, missiles, local,

pressurizations, pipe break reaction forces, and decompression waves in the intact portions of that piping or communication piping.

Although LBB piping will not rupture, provided leakage limits are met, global effects of steam generator secondary j

side piping line breaks are addressed in safety analyses, consistent with Draft Standard Review Plan 3.6.3 (Ref. 3)

Although'the secondary coolant system leakage limit is not required by any of the criteria of the NRC Policy Statement, this specification has been included in Technical Specifications in accordance with NRC direction (Ref. 4).

LCO This LCO ensures that the leakage from steam generator secondary side LBB lines inside containment associated with i

the critical crack size assumed in the LBB analysis is not exceeded. This leakage limit precludes LBB pipe rupture, thus preserving the equipment qualification design basis.

The LC0 3.4.10 instrumentation along with other available instrumentation provides the capability to establisie the leak source (Ref. 2).

APPLICABILITY In MODES 1, 2,3, and 4, when the SG is being used for RCS heat removal, the secondary system pressure and temperature conditions are capable of causing pressure boundary growth of a critical size crack which in combination with an SSE could result in pipe rupture.

i i

The secondary system temperature and pressure conditions in MODES 4, 5, and 6, with RCS cooling provided by the normal residual heat removal system (RNS), are not sufficient to propagate a leakage crack. Additionally, the local dynamic effects of a postulated pipe rupture in MODES 4, 5, and 6, with RNS cooling, are insignificant from the standpoint of equipment qualification design bases for essential structures, systems, and components. Therefore, leakage monitoring is not required in MODES 4, 5, and 6, with RCS a

4 cooling provided by the RNS.

i ACTIONS A.1 With secondary coolant system pressure boundary leakage into

- containment in excess of the LCO limit, action must be taken.

to reduce the leakage within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months . This Completion Time is based on predicted crack growth rate and allows time to isolate the leak or take other appropriate action to reduce the leak rate.

This action is necessary to prevent further deterioration of the secondary coolant system pressure boundary.

B.1 With steam generator secondary side leakage in excess of the limit, the unit is in a condition potentially outside the LBB analysis. Therefore, the unit must be placed in MODE 4 with RCS cooling provided by the RNS, where the probability and consequences of crack growth in the secondary coolant system pressure boundary inside containment are minimized.

To achieve this status, the plant must be placed in at least MODE 3 within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months , and in MODE 4, with RCS cooling provided by the RNS, within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

The allowed Completion Times are reasonable, based on operating experience, to reach the required conditions from full power, in an orderly manner, and without challenging plant systems.

Cindy Haag FROM:

Bill Huffman SUBJ:

AP600 T-H Uncertainty RAI Responses

Cindy, below are some of Alan Levin's comments on the RAI responses provided in your August 30, 1996 submittal on T-H uncertainty.

If you can have some kind of kritten response prepared for our Friday afternoon telecon, I will write a telecon summary which will document the responses.

RAI 492.15 Please provide a quantitative estimate of what Westinghouse considers " ample margin' to the PCT limit as discussed in this response.

Regarding the response to how margins will be reflected in the overall baseline PRA, Westinghouse has indicated that scenarios which have less than it. impact on the focused PRA will not be considered. Although this may be justifiable for the focused PRA, scenarios that are less than 1% of the focused PRA frequencies are of the same order of magnitude as

,the baseline PRA and would appear to potentially impact the baseline results.

Please provide additional information on this.

492.21 The response to this question did not specifically address the staff's concerns.

It is understood that during steam cooling conditions there is relatively little difference in the results if either ' good" or " poor" heat transfer is assumed.

The staff is more interested in the heat transfer during the transition from covered to uncovered and the return to covered.

For those sequences in which the core uncovers but

" damage" is not predicted because the core recovers before PCT exceeds whatever cutoff is established (to account for

" adequate margin), the timing and modeling of the transition from nucleate boiling to steam cooling and vice-versa may have a significant effect on the predicted peak temperature.

It is for this reason that it would appear that core heat transfer should be a high-importance phenomenon (it is tied to some extent to calculation of the two-phase level, as well).

The transition of most interest is probably trom uncovered to rewetted.

It is assumed that dryout is modelled as essentially concurrent with reaching a void fraction of 1 at a particular level (though that may not,actually be the physical case). However, depending on the rod surface temperature when the mixture level recovers, ' quenching" may well not coincide with the mixture level reaching a given elevation.

If there is a delay between recovery and rewet, the calculation of film boiling heat transfer and the transition to nucleate boiling is important.

492.23 The staff's question regarding this RAI response is how ons differentiates between the importance of one source of ECC l

injection and another in terms of its PIRT ranking.

Westinghouse did not address this aspect in the response.

l l

l

I t

In addition, the response states that there "is no modelling consideration of whether RNS prevents ADS-4 actuation.'

It was the staff's understanding that if RNS was available in a baseline PRA LOCA event tree, it affected the consideration of whether ADS-4 was needed--i.e., failure of ADS-4 would not need to be considered in the event tree.

Please provide additional information on the role of RNS in the baseline PRA.

492.24 The response to this RAI does not clarify how Westinghouse will treat the discharge coefficient for breaks that are near or equal to the pipe diameter in question.

Specifically, for full diameter breaks (or equivalent), how would Westinghouse establish the break coefficient impact without varying it explicitly. The staff has seen analysis results from Westinghouse that appeared to indicate that relatively small changes in this parameter could cause significant changes in calculated peak temperatures (although it was not clear why that should have been the case). The RAI response does not provide a convincing argument that the break discharge coefficient should not be an important parameter in the PIRT.

Westinghouse should be prepared to explain the values of discharge coefficients used in the T-H analyses and why they are conservative.

492.'25 Please provide some elaboration on this response. For instance, if both NOTRUMP and KAAP.show the same ' trend

of decreasing core mixture level, but NOTRUMP uncovers and MAAP does not, is that "okay* or "not okay?" Further, the second part of the answer seems in part to contradict the first, or at least, they do not appear entirely consistent. For the first paragraph, if differences in the trend are, in fact,

' caused by a "well-defined deficiency in MAAP4' does this mean that the comparison is 'okay?"

(That's what the sentence seems to say.)

If there is a 'well-defined deficiency in MAAP4," wouldn't this be a case where (in para. 2)

phenomena are encountered that are beyond the capability of MAAP4?'

(i.e., doesn't a deficiency imply a situation beyond the capability of the code?)

492.30 The staff notes that one aspect of a SGTR that distinguishes it from a SBLOCA scenario is the potential for containment bypass. Westinghouse should address this difference when it prepares the pertinent documentation the discusses SGTRs rad SBLOCAs l

This provides additional justification of classification of the main condenser evacuation system as a Class E system. NRC has questioned this classification in light of the Standard Review Plan and Regulatory Guide 1.26 in this area. Regulatory Guide 1.26 indicates that Class D standards should be applied to water-or steam-containing components not classified in a higher class that contain or may contain radioactive material. The main condenser evacuation system and the gland seal system in AP600 do not contain radioactive material. They may contain radioactive material if there is a steam generator tube leak that allows radioactive material to be introduced into the systems without appropriate stern system isolation. In such an event, the evacuation and gland seal systems may draw in radioactive material from the steam spaces in the condenser or turbine.

AP600 SSAR section 3.2.2.7 contains the conditions for which "may contain radioactive material" do not require classification of components in Class D:

The system is only potentially radioactive and does not normally contain radioactive material.

This is true for the evacuation and gland seal systems in a pressurized water reactor like AP600 where the, steam generator provides and effective barrier to the primary coolant.

The system has shown in plant operations that the operation with the system containing radioactive material meets or can meet unrestricted area release limits. Studies have shown that once a ;:nall steam generator leak is detectable it is still small enough to meet unrestricted area release limits. Automatic and techspec limits are exceeded well before unrestricted area release limits. For very large steam generator leaks, other operating parameters provide trip and isolation actions befcre exceeding unrestricted area release limits.

. An evaluation of the system confirms that the system contams features and components that keep the consequences of failure as low as reasonably achievable. This portion of AP600 is' very similar to many operating pressurized water reactor plants. There is a low probabdity of leakage and there are radiation monitors and radiation limits on the main steam system and evacuation exhausts. This has resulted in good performance record of no release from this source greater that unrestricted area release limits.

As a result of meeting these three conditions for not being Class D, the evacuation and gland seal systems are Class E.

NRC REQUEST FOR ADDmONAL INFORMATION i

l Revision 1 m-Question 410.115-R1 Describe how AP600 SWS is designed to minimize the potential for water hammer.

Response

Prior to system stanup, the service water system (SWS) is filled with water and vens'--ee" e^::f-- 9.2.!.3.1. During normal operauon, the SWS pumps water from the basia at the SWS cooling tower, through piping and equipment, to a high point located at the SWS cooling tower riser; the cooling water is then discharged to atmosphere in a spray fashion above the cooling tower basin. The system arrangement is such that there are no high points in the system piping that can lead to formation of vapor pressure voids upon loss of system pumping.

When the pumps are stopped, check valves located at the discharge of each pump minimize reverse flow of system fluid through the-pumps and into the basin; alsc, :":; :: ifn-5 '::'- ' -in. S ;-----

r=: :;; _i if both pumps stop due so loss of normal ac power, cooling tower blowdown is isolased. Therefore, drain down of system fluid is minimized when the system is shut down. Drainage that might occur, : _:t x 'l_ _ f S :- " ""

.:: : :" ; " : is replaced by air. No vapor cavities will form. Therefore, the potential for water hammer due to water column rejoining upon pump r.. tart is minimized.

Motor operated valves at the discharge of each SWS pump are interlocked to close prW to pump start. These valves then open at a controlled rees following pump start to slowly admit waner to the system.1his feature results is reduced fluid velocities during system start and minimizes transiest effiscts that may occur as the system sweeps out any-air and obtains a water solid condition. Temperatures in the system are moderate and the pressure of the SWS fluid is kept above its saturanos pressure at all locanons. 1herefore, the poseanal for waaer hammer due to thermodynamic voeding and subsequent vapor collapse is minimi==d These are no fast acting power-operased valves in the system, and the only check valves in the normal process flow path are in a standard configuranon at the discharge of each SWS pump. Therefore, the design of the system minimizes water hammer potential due to rapid valve actuanos.

In t!e event of loss of normal ac power, the service water pumps and cooling tower fans, along with the associated motor operated valves are automatically loaded onto their associated diesel bus. This includes isolation of cooling tower blowdown, which mlat=l= drain down of the system while both pumps are off.

What drainage that does occur is replaced by air without vapor cavities. The potential for water hammer on pump restart is minimized. Both pumps and both cooling tower cells automatically start after power from the diesel generator is available. Following automatic start, the operator may return the system to the appropriate configuration.

Describe how the information in this table provides the above information. Where is the permissible cooling water leakage? Where is the infonnation of length of time that the condenser may operate with degraded conditions without affecting the condensate /feedwater quality for safe operation? What are the definition of the action levels (1,2, and 3) listed in Table 10.3.5-17 Also, provide j

information in the SSAR regarding the procedure to repair condensate leaks in accordance with Section 10.4.1 of RG 1.70.

Response

SSAR subsection 10.4.1.2.1 is intended to convey that there is no absolute value of cooling water inleakage nor specific time of operation for maintaining the required condensate or feedwater quality. The measured parameten that affect plant performance and operator actions are the water quality values in SSAR Table 10.3.5-1. As a basis for design of the condensate polishing system, cooling water inleakage of.001 gpm " continuous" and.1 gpm

" faulted" are used. These values are identified in SSAR subsection 10.4.6.1.2. Note that the circulating water system described in the SSAR is for reference only. Any certified AP600 may have another type or source of circulating water. As a result, the effect of.001 gpm inleakage of cooling water on condensate or feedwater will vary from plant to plant. Thus the real limit on inleakage is on the resultant quality of condensate and feedwater and not on 4

the amount of time of cooling water inleakage. Once condensate or feedwater quality are degraded to outside the limits contamed in Table 10.3.5-1, the operator should take actions consistent with the EPRI NP-2701, PWR Secondary Water Chemistry Guidelines. 'Ihis EPRI document defines action levels I,2 and 3 and the actions required for each. SSAR subsection 10.4.1, Revision 6, provides a description of the procedure for repairing condensate tube leaks.

10. Steam and Power Coenrsion Sp m-CHAPTER 10 STEAM AND POWER CONVERSION SYSTEM 10.1 Summary Description The steam and power conversion system is designed to remove heat energy from the reactor coolant system via the two steam generators and to convert it to eisctrical power in the turbine-generator. The main condenser deaerates the condensate and transfers heat that is unusable in the cycle to the circulating water system. The regenerative turbine cycle heats the feedwater, and the main feedwater system returns it to the steam generators.

Table 10.1-1 gives the significant design and performance data for the major system components. Figure 10.1-1 shows the heat balance for the tubine cycle process.

10.1.1 General Description 2

The steam generated in the two steam generators is supplied to the high-pressure turbine by j

the main steam system. After expansion through the high-pressure turbine, the steam passes through the moisture separator / reheater (MSR) and is then admitted to the two low-pressure turbines. A portion of the steam is extracted from the high-and low-pressure turbines for -

seven stages of feedwater heating.

Exhaust steam from the low-pressure turbines is enadaaerd and deaerated in the main condenser. The heat rejected in the main condenser is removed by the circulating water system (CWS). The condensate pumps take suction from the condenser botwell and deliver the condensate through four stages of low-pressure closed feedwater heaters to the fifth stage, open deaerstmg heater. Condensate then flows to the suction of the steam generator feedwater booster pump and is discharged to the sucuon of the main feedwater pump. The steam generator feedwater pumps discharge the feedwater through two stages of high-pressure feedwater heaters to the two steam generators.

The moisture separator. drain is pumped to the deaerator.

The reheater drams and high-pressure feedwater heater drains c==cada into the deaerator. Drams from the low-pressure feedwater heaters are caecadan through mecanively lower pressure feedwater heaters to the main raadaaw.

,.tp.t af At The Westinghcuse turbine generator has : s..O '

.e.

ef 675,000 kW for the Westinghouse nuclear steam supply system (NSSS) thermal output of 1,940 MWt. The prmeipal turbine-generator conditions for the turbine rating are listed in Table 10.1-1. The raied system E+iW-3 for the NSSS are listed in Table 10.1-1. The systems of the turbine cycle have been designed to meet the maximum expected turbme generator conditions.

Instrumentanon systems are designed for the normal operanng conditions of the steam and condensate systerns. The systems are designed for safe and reliable control and irs-pe.k 1

9.2.1.2.3.3 Power Operation De service water system, during normal power operation, provides cooling water at a i

maximum temperature of 89'F to the component cooling water heat exchanger in service.

t l

One semce water pump and one cooling tower cell are in service. De flow rate and heat load are shown in Table 9.2.1-1.

l De standby service water pump is automatically started if the operating pump should fail, thereby providing a reliable source of cooling water. De system is designed so either pump can serve as the operating or standby pump.

9.2.1.2.3.4 Plant Cooldown/ Shutdown

?

During the plant cooldown phase in which the normal residual heat removal system has been placed in service and is providing shutdown cooling, the semce water cooling tower providea l

cooling water at a temperature of 88.5'F or less when operstmg at design heat load and at an j

ambient wet bulb temperature of no greater than 80*F (1 percent exceedance). Two service j

water pumps and two cooling tower cells are normally used for plant cooldown, and the cross-connection valves between trams are normally closed. De semce water system heat load and i

flow rate are shown in Table 9.2.1-1. Durms these modes of operation the normal residual,

heat removal system and the component cooling water system remove sensible and decay heat l

from the reactor coolant system. In the event of failure of a service water system pump or

remaining item will be " closed" upon submittal of our ITAACs, and has been i

identified as an ITAAC Open Item. The "(NRC) Status" for the 27 shown by l

"(W) Status" as " Closed" includes 9 that are " Resolved." Westinghouse knows i

of no submittal requirements for the other 18. It is our intent to supply NRC l

with all information necessary for it to write the Chapter 7 portion of the FSER i

revisions or information for Chapter 7 itself (except for the ITAAC item identified above) and we should have a teleconference definitely scheduled to j

resolve any remaining NRC concern.

 Because pipe rupture is precluded, the equipment qualification design bases for equipment in the LBB pipe local area do not include conditions associated with pipe rupture. The primary advantage of this approach is that for, these lines, the pipe restraints are not designed to withstand forces and displacements associated with a pipe rupture (Ref. 1).

+This provides additional justification of classification of the main condenser evacuation system as a Class E system. NRC has questioned this classification in light of the Standard Review Plan and Regulatory Guide 1.26 in this area. Regulatory Guide 1.26 indicates that Class D standards should be applied to water-or steam-containing components not classified in a higher class that contain or may contain radioactive material. The main condenser evacuation system and the gland seal system in AP600 do not contain radioactive material. They may contain radioactive material if there is a steam generator tube leak that allows radioactive material to be introduced into the systems without appropriate stern system isolation. In such an event, the evacuation and gland seal systems may draw in radioactive material from the steam spaces in the condenser or turbine.

 AP600 SSAR section 3.2.2.7 contains the conditions for which "may contain radioactive material" do not require classification of components in Class D:
 The system is only potentially radioactive and does not normally contain radioactive material.
 This is true for the evacuation and gland seal systems in a pressurized water reactor like AP600 where the, steam generator provides and effective barrier to the primary coolant.
-The system has shown in plant operations that the operation with the system containing radioactive material meets or can meet unrestricted area release limits. Studies have shown that once a ;:nall steam generator leak is detectable it is still small enough to meet unrestricted area release limits. Automatic and techspec limits are exceeded well before unrestricted area release limits. For very large steam generator leaks, other operating parameters provide trip and isolation actions befcre exceeding unrestricted area release limits.                            -

-          . An evaluation of the system confirms that the system contams features and components that keep the consequences of failure as low as reasonably achievable. This portion of AP600 is' very similar to many operating pressurized water reactor plants. There is a low probabdity of leakage and there are radiation monitors and radiation limits on the main steam system and evacuation exhausts. This has resulted in good performance record of no release from this source greater that unrestricted area release limits.

 As a result of meeting these three conditions for not being Class D, the evacuation and gland seal systems are Class E.

 ===Response===
 Prior to system stanup, the service water system (SWS) is filled with water and vens'--'''ee" e^::f-- 9.2.!.3.1. During normal operauon, the SWS pumps water from the basia at the SWS cooling tower, through piping and equipment, to a high point located at the SWS cooling tower riser; the cooling water is then discharged to atmosphere in a spray fashion above the cooling tower basin. The system arrangement is such that there are no high points in the system piping that can lead to formation of vapor pressure voids upon loss of system pumping.

 seven stages of feedwater heating.
 Exhaust steam from the low-pressure turbines is enadaaerd and deaerated in the main condenser. The heat rejected in the main condenser is removed by the circulating water system (CWS). The condensate pumps take suction from the condenser botwell and deliver the condensate through four stages of low-pressure closed feedwater heaters to the fifth stage, open deaerstmg heater. Condensate then flows to the suction of the steam generator feedwater booster pump and is discharged to the sucuon of the main feedwater pump. The steam generator feedwater pumps discharge the feedwater through two stages of high-pressure feedwater heaters to the two steam generators.
