/PSAR Reference Significant Changes Since'PSAR accommodate cold shutdown. .

10.3.2 11ain steam supply system changes include:

/10.3.1.2

1. Replaced nonreturn valves with main steam isolation valves to prevent reverse flow of fogg h M steam reduction.

in event of accidental pressure

] ,2. liain steam line trip valves changed from NhpDr.J ' swing disk-type to hydraulically-operated ball type, held open by solenoid-cperated 4/

[

k ^md3W.N mechanical latch.

k 3. Parallel trip valve configuration for turbine-driven auxi_iary feedwater pump steam supply changed. Presently, three pairs of series solenoid-operated trip valves are provided, one pair in each of the three 3-inch lines between the 32-inch main steam line and the 3-inch turbine drive common

. header.

P

  • 10.4.4 Added cooling tower pumps and low-low Tavg

/10.3.1 permissive interlocks to turbine bypass control ,

valves capabilities.

10.4.5 Circulating water system changes include

/10.3.4

1. Total dynamic head of cooling tower pumps reduced from 96.4 feet to 73 feet through use of natural draft counter-flow cooling tower with its lesser static lift requirements.
2. Addition of flood indicators to valve pits on suction side of cooling tower pumps, inlet and outlet sides of condenser, and turbine building retention pit, all with flood alarms to main control room.

10.4.6 Addressed new condensate cleanup system, a

/lione IMS class system, consisting of two subsystems, condensate polishing system and powdered resin dewatering system. 4 l

10.4.7.2 Changes to condensate and feedwater . systems I

NN BVPS-2 FSAR The performance requirements of the MSSS are shown on the heat belance diagram, Figure 10.1-1, with the design and performance characteristics shown in Table 10.1-1. The MSSS is designed for 1,100 psia and 560 F, and the environmental design criteria is specified in Section 3.11 for the Class 1E components.

10.3.2 Description Steam from each of the three steam generators passes through 32-inch outside diameter (OD) carbon steel pipes. A steam flow meter, interconnected with a three-element feedwater _ control system, is provided in the main steamline at the outlet of each steam generator.

A MSIV in each of the three main steamlines is lecated in the main steam valve house, immediately outside the reactor containment.

Following the MSIVs, the three main steamlines enter a single, 38-i inch OD manifcid. Connections for the turbine steam bypass, l turbine steam sealing system, reheater supply, and auxiliary stcam supply are provided at the manifold.

From this manifold, steam passes to the turbine step trip valves and governor valves.

The MSIVs autcmatically prevent reverse flow of steam in case of accidental pressure reduction in any steam generator or its piping.

If a steamline breaks between a MSIV and a steam generator, the affected steam generator continues to blow down while the isolation valve prevents blowdoun from-the other steam generator. In addition,

! the MSIVs prevent blowdown through a ruptured pipe downstream of the isolation valves. This steamline break accident is discussed in 1 (hhhtiGL,s4E'TN96 Pr*(.umM ICCBAN The 63Ti- d MSIVs are opened vor- ~ 3 and are held cpen by

If a pipe ruptures either upstream or downstream of an isolation valve V(e<t .eep solenoidsto release Da ma'n steamline isolation sional causes.a.

spring force. .in.1 I nch, closing the valve by receipt of the signal is 5 seconds. time Maximum closing for the isolation valve upon Valve closure prevents rapid r

prevents rapid cooling of the RCS. The llSIV closure also ensures a supply of steam to the turbine-driven auxiliary feed pump.

Single failure of a !!sIV is discussed in Section 15.1.S. Further discussion of main steam system component failure can be found in Sections 15.1 and 15.2.

If a main steamline breaks between a !!SIV and a steam generator, only that steam generator vill blow down. Closure of the 11SIV in the.

ruptured line prevents blowdown from the other steam generators.

The maximum capacity of any single main steam safety valve, steam bypass valve. residual heat release valve or atmospheric dump valve does not exceed 890,000 lb/hr at 1,100 psia inlet pressure. This feature limits the potential uncontrolled blowdown flow rate in the event a valve inadvertently fails or sticks in the open position.

To prevent a postulated large steam flow blowdown from more than one steam generator due to the valve failing or sticking open the residual heat release valve is normally aligned to only one steam generator. However, the valve can be aligned to any one of the three steam generators.

Failure modes and effects analyses (FHEA) to determine if the instrumentation and centrol and electrical portions meet the single failure criterion, and to demonstrate and verify how the General Design Criteria and IEEE Standard 279-1971 requirements are satisfied, have been performed on the main steamline isolation system. The FHEA methodology is discussed in Section 7.3.2. The results of these analyses can be found in the separate FHEA document (Section 1.7).

10.3.4 Inspection and Testing Requirements Piping and equipment of the USSS designed ^as Seismic Category I require preoperational and periodic in-service testing. For discussion on preoperational tests, refer to Chapter 14.

Section 3.9B.6.2 discusses in-service tests of valves. In-service tests of other Class 2 and Class 3 components are discussed in Section 6.6.

Test requirements of the HSIVs in the USSS are as follows:

, the time of . procurement fot BVPS-2. Due to successful power plant 4

operating experie. s with the materials .of construction, fracture toughness testing was not generally specified for the main steam and feedwater system piping and components. Fracture toughness testing was specified, however, for the weld filler metal used in the field

.; erection of piping. Tes:ing is to the requirements of ASME Code j Section III, HB 2400, and the applicable ASME Code Section II, j Part C, filler material specification. In addition, where components 1

J were fabricated to later editions of ASHE Code Section III that required fracture tougnness testing, this testing was performed in i

accordance with the code then in effect.

BVPS-2 FSAR NOTES TO TABLE 7.5-1

(-)

(' 1.

Quality Assurance is in accordance with the BVPS-2 program defined in FSAR Chapter 17.

2. EOF and TSC indications of the BVPS-2 Post Accident Monitoring Instrumentati,on will be addressed in the TSC and EOF submittals.
3. The BVPS-2 Design Basis only identified the key variables that are used for monitoring the performance of safety systems and other systems normally employed for attaining a safe shutdown condition. In accordance with the definitions in the Design Basis, these variables are designated, Type D, Category 2. The preferred backup variables to the YypeeD variables are not specified in this document.- Since these variables are designated Type D, Category 3, the instrumentation is only required to be high quality commercial grade without any post-accident environmental qualification. A decision was made not to specifically identify the potential long list of instrumentation available at BVPS-2 that meets this definition. Indeed, if the list was generated, it would be much more inclusive than the variables identified in Reg. Guide 1.97, Revision 2.

4.

The installed equipment is a standard Westinghouse Nuclear Instrumentation system, powered from a battery backed Class 1E Power Source. The equipment contains isolated monitoring channels which cover the range required to be monitored. The

(N equipment is suitable for normal operation, and the qualified

(_,) instrument rack portion is installed in the control room which is an accessible sensors are and controlled mild environment. Currently, no commercially available with post-accident environmental qualification; therefore, no implementation schedule can be provided at this time. Borating the primary system after an accident in accordance with the EOPs ensures that adequate shutdown margin is maintained.

5.

BVPS-2 is installing the Westinghouse differential pressure Reactor Vessel Level Instrumentation System (RVLIS). This is an acceptable system for measuring coolant level in the reactor according to Generic Letter 82-28. BVPS-2 uses Core Exit Temperature the Westinghouseand RCS Subcooling to support operation according to Owners Group Emergency Response Guidelines.

These guidelines require that the RVLIS meets Regulatory Guide 1.97 Category 2 criteria only. Operator verification of flows I during safety injection operation and stringent termination criteria preclude the need for RVLIS under design basis accidents.

6. Pressurizer Heater Status -

Regulatory Guide 1.97, Rev. 2, spe. .fied that heater current was the preferred parameter for determining heater status. For BVPS-2 heater breaker position,

Amendment 5 of 11 February 1984

BUPS-2 FSAR

  • NOTES TO TABLE 7.5-1 (Cont) not current indication, was selected for determining pressurizer O

heater status due to hardware considerations. Breaker position provides adequate indication to the operator to ensure the pressurizer heaters are op,erable.

7. The recommended ranges for this instrumentation are Wind speed 0 to 67 and -9 to 18'F for estimation of atmospheric stability.

The instrumentation to be installed will cover the following ranges: Wind speed 0 to 50 mph and estimation of atmospheric stability T (150-35 ft) -4.0

+12.0*F.

to +8.0'F: (500-35 ft) -6.0 to The instrumentation fosp. rind speed meets the guidance of Regulatory Guide 1.23. The vertical temperature ranges cover the range of lapse rates (change of temperature with height) guidance of Reg. Guide 1.23 required to estimate the atmospheric stability class.

8.

The licensing basis used in the BVPS-2 Regulatory Guide 1.97, Revision 2 Design Document was that a safe shutdown condition was a hot standby condition. Parameters necessary to monitor the status of the plant while proceeding to a cold shutdown condition are not included in the Design Document. The accumulator pressure, nitrogen accumulator isolation valve status, and accumulator vent valve status were identified as Category 2 only if the plant has committed to safety grade cold shutdown.

9.

The Westinghouse Owner's Group Emergency Response Guidelines do not consider boric acid charging flow as a parameter to be used by operators during or following an accident. Under these conditions borated water is pumped from the large volume RWST into the RCS. BVPS-2 has designated RWST level, HHSI flow, LHSI flow, containment water level, and emergency core cooling system (ECCS) valve status for monitoring the performance of the ECCS since tank.

the ECCS does not normally take suction from the boric acid If boration is used following an accident, qualified charging flow indication and RCS sampling are used to demonstrate that the RCS is being adequately borated.

10. The and installed instrumentation is designed to Category 3 criteria the measured temperature is from O' to 200*F. The Westinghouse Owner's Group Emergency Response Guidelines do not require operator action based on containment temperature indication, but rather use containment pressure indication, therefore containment temperature is considered a Category 3 parameter, operation.

and the existing range is adequate for normal j

11. The Westinghouse Owner's Group Emergency Response Guidelines do not require operator action based on containment sump water temperature indication.

I At saturated condition, sump water Amendment 5 10 of 11 February 1984

BVPS-2 FSAR NOTES TO TABLE 7.5-1 (Cont) temperature can be inferred from containment pressure.

containment spray system valve status and containment spray flow indications are used to demonstrate that the Emergency Core Cooling System is operating properly when taking suction from the containment sump.

12. Note that although these Category 2, valves are classified as the associated instrumentation meets the qualification requirements for Category 1 instrumentation as discussed in FSAR Section 7.5.2.1.3.1, with the exception of 2CHS*FCV160 and 2CHS*HCV142 See. Table 6.2-60). These valves are closed during normaI(plantoperation and post-accident conditions,: and are powered from non-Class 1E sources.
13. Under Implementation Date, " complete" means that this instrumentation already exists in the current design. All instrumentation will be installed by fuel load unless otherwise noted.

The main steam pressure transmitters are environmentally

qualified for all events with the exception of the arbitrary 1.0 fta MSLB in the main steam valve house imposed by NRC-BIP-ASB 3-1. The resultant environment produced by the 1.0 fta break exceeds the qualified temperature of the y transmitters' instrument cable. Failure of the cable has no adverse effect on RPS or SLI signal generation as the cables perform temperature.
