6.1-1Reformatted PerAmendment 02-016.0ENGINEERED SAFETY FEATURESThe central safety objective in reactor plant design and operation is control of reactorfission products. The methods used to assure this objective are:1.Design of the reactor core in conjunction with the reactor control and protectionsystems to preclude release of fission products from the fuel (Chapters 4 and 7).2.Retention of fission products in the Reactor Coolant System (Chapters 5 and 6).

3.Retention of fission products by the containment for operational and accidentalreleases beyond the reactor coolant boundary (Sections 3.8 and 6.2).4.Limiting or optimizing fission product dispersal to minimize population exposure foran accidental release beyond the containment (Chapters 2 and 11).The engineered safety features are the provisions in the plant which embody methods 2and 3 above to prevent the occurrence, or to ameliorate the effects, of seriousaccidents.6.1GENERALThe engineered safety features are:

1.ContainmentThe reactor building provides a virtually leaktight barrier to the escape of fissionproducts. Detailed information on the containment is provided in Section 6.2.1.2.Reactor Building Heat Removal SystemsThese systems serve to reduce reactor building pressure and temperature. These systems are discussed in detail in Section 6.2.2.3.Reactor Building Air Purification and Cleanup SystemsThe function of these systems is to provide air purification and cleanup services to the Reactor Building. These systems are discussed in Section 6.2.3.4.Containment Isolation SystemThis system provides containment isolation capability for the various system lines penetrating the containment. Detailed discussions of this system are presented inSection 6.2.4.

02-01 6.1-2Reformatted PerAmendment 02-015.Combustible Gas Control SystemThis system acts to control the concentration of hydrogen, oxygen, and othercombustible gas which may be released to the reactor building to assurecontainment integrity. This system is discussed in Section 6.2.5.6.Containment Leakage Testing.Containment leakage testing provisions are discussed in Section 6.2.6.7.Emergency Core Cooling SystemThis system delivers borated water to the reactor core to provide core cooling following postulated accidents. The boron, together with the control rods providessufficient negative reactivity for safe shutdown following design basis accidents.

The Emergency Core Cooling System is discussed in detail in Section 6.3.8.Habitability SystemsThese systems provide the control room with adequate shielding, air purification, and climatic control. These systems are discussed in Section 6.4.9.Fission Product Removal and Control SystemsThe fission product removal systems include the high efficiency particulate air filters in the Reactor Building cooling system and the control room emergency filterplenums. This equipment is discussed in Section 6.5.

Notes: 1. With respect to containment. 2. The following notes 3 and 4 are applicable to the design of the reactor baffle system. 3. These values are for 150 sq. ins. break and apply to original design of the baffles before the deign details were changed in 1978 to accommodate a revised construction sequence. These loads were increased by a dynamic load factor of 1.5 for structural design.

4. For Nodes 28, 29 and 32 the peak differential pressures were also evaluated for a break size of 100 sq. ins. in 1978 and 127 sq. ins. in 1988. The 127 sq. in. break values were obtained by interpolation of the pressure/temperature analyses for the 100 sq. in. and 150 sq. in. breaks. The calculated peak and design differential pressures (with respect to annulus) shown are for the 127 sq. in. break which is the maximum expected break size that can occur. These values were increased by a dynamic load factor of 1.2 for structural design.

Reactor building spray pump Fails to start. Since each of the two sub-systems of the reactor building spray system is equally sized, the remaining subsystem

provides heat removal capability

at a reduced rate. In

combination with the reactor building emergency cooling system, heat removal capability in excess of the requirements is

provided. Elemental iodine

removal is adequate with one

subsystem operating.

2. Reactor building isolation valve.

Fails to open. (Same as above.) 3. Check valve in suction line.

Fails to open. (Same as above.) 4. Sodium hydroxide tank discharge

valve. Fails to open. The redundant discharge valve admits adequate sodium

hydroxide to the other

subsystem to provide the

required iodine removal.

6.2-226 Reformatted Per Amendment 02-01 TABLE 6.2-52 SINGLE FAILURE ANALYSIS - REACTOR BUILDING HEAT REMOVAL AND FILTERING SYSTEM Component Malfunction Comments 1. Air Handling Unit Fan Motor Fails to start or fails to start at low speed.

Cooling continues from the

remaining operating unit with

supplemental cooling from the spray system.

2. Cooling Coils Rupture The coils are designed for

hydrostatic testing at 200 psig

which is in excess of the design

service water pressure. However, if rupture occurs, cooling continues

as noted under item 1 above.

3. Plenum and Ductwork Rupture The plenums and connected ductwork are designed to

withstand the post accident pressure transient and the systems

are sufficiently separated so that

the effects of a pipe break or missile are confined to a single unit. Thus, rupture of a portion of the system or a single component does not prevent continued cooling

as noted under item 1 above.

4. Cooling Water Piping Rupture The piping for two of the units is physically separated from that of

the remaining two units and is

designed as Seismic Category I.

Thus, rupture of a portion of the

system does not affect all units

and does not prevent cooling as

noted under item 1 above. 00-01 00-01 00-01 6.2-227 Reformatted Per Amendment 02-01 TABLE 6.2-52 (Continued)

SINGLE FAILURE ANALYSIS - REACTOR BUILDING HEAT REMOVAL AND FILTERING SYSTEM Component Malfunction Comments 5. Water Control Valves Fail to operate. The valves are used for switching from the normal cooling water supply to the service water supply

during a post accident period. The

valves are redundant and are periodically tested. Failure of a single valve does not prevent

cooling as noted under item 1

above.

6. HEPA Filter Bypass Duct Fails to operate. Failure of the dampers in the normal position results in loss of filtering ability but not in loss of

cooling for the affected units.

NOTES TO FIGURE 6.3-2 (Sheet 1 of 4)

1. Westinghouse process flow diagrams are provided for illustrative purposes only and are not intended to represent the flow rates used by Westinghouse in various accident analyses. Flow rates to the RCS are provided in Chapter 15, where appropriate. The process flow diagrams are developed to prov ide representative best estimate system performance data based on minimum safeguards systems

alignment. The flow rates in the FSAR accident analyses are developed based on pump test curves degraded by 5 - 7 percent (see Section 6.3.3.1) and worst case assumptions pertaining to spilling line system resistances (e.g., maximum

allowable resistances in lines connect ed to unbroken loops and minimum allowable resistances in the line connected to the broken loop) an d RCS pressures. 00-01 00-01 RN 03-006

2. The minimum safeguards alignments are for Train A components only. Minimum alignments assume a loss of power to Tr ain B at the beginning of the event.
3. Charging pump suction and discharge valves are listed as Closed during the recirculation mode. In ac tuality, two suction and two dis charge header valves will be open, depending on which charging pumps are in operation to establish two

separate high head recirculation discharge flowpaths. (Reference Table 6.3-3)

4. RHR minimum recirculation valves are controlled automatically. During periods of low RHR injection flow rates, these valv es open to maintain pump minimum flow requirements. (Reference Section 6.3.2.2.4.1)
5. In order to minimize procedure comp lexity, the preferred lineup for hot leg recirculation is to align the Charging SI pumps to the RCS cold legs and the RHR SI pumps to the hot legs. Adequate core cooling is ens ured with either the preferred lineup or by aligni ng Charging SI pumps to the hot legs and the RHR SI pumps to the cold legs.

Table 6.5-1 provides a comparison of the emergency filt er systems with the requirements of Regulatory Guide 1.52. General compliance with Regulatory Guide 1.52 is discussed in Appendix 3A.

6.5.1.3 Design Evaluation The general arrangement and control of the ESF filter systems are described in Sections 6.2.2, 9.4.1, and 9.4.3. System com ponents are separated, redundant, powered by Class 1E electric systems, and are housed in Seismic Category 1 structures. The control room system is not subject to jet impingement, pipe whip or flooding. The HEPA filter systems in the Reactor Building are physically separated so that no more than 1 unit is subject to thes e occurrences. The Fuel Handling Building charcoal exhaust system plenums are housed in shielded and separated cubicles. The exhaust fans of this system are adjacent to each other. Neither the exhaust fans nor the filter plenums are subject to jet impingement, pipe whip or flooding. The ESF filter systems can sustain a single component fail ure without impairing their full functional capability. Additionally, provision is made for suit able maintenance and change-out space and adequate instrumentat ion and lighting, all of which reduce personnel exposure by reducing time exposure.

The control room emergency filter system is required in the event of radioactive leakage from the outside into the Cont rol Building following a LOCA. Post LOCA operation of the control room filter systems is ensured by automatic actuation as a result of a safety injection signal or high radiation in the c ontrol room signal from the radiation monitor (RM-A1).

6.5-2 Reformatted Per Amendment 00-01 The Reactor Building cooling system and contro l room emergency filter trains provide a minimum of 99.97 percent removal efficienc y for particulates. The control room emergency filters also provide a minimum of 95 percent removal efficiency for methyl iodine at 85 percent relative humidity and 70 F (see Reference [1]).

6.5.1.4 Tests and Inspections 99-01 Details of the tests and inspections for t he ESF filter systems are provided in the following sections:

6.2.2.4.2 - Reactor Building Cooling System HEPA Filters

9.4.1.4 - Control Ro om Emergency Filters

9.4.3.4 - Fuel Handling Building Charcoal Exhaust System

Laboratory tests, inplace tests, and test acce ptance criteria are in accordance with the requirements of Regulatory Gu ide 1.52 (see Table 6.5-1).

6.5.1.5 Instrument ation Requirements Each of the ESF filter systems include instrumentati on for system performance and status monitoring during normal plant oper ation, system tests, and system operation following a design basis accident. The instru mentation and control features of the ESF filter systems are described in Se ctions 6.5.1.5.

1 and 6.5.1.5.2.

6.5.1.5.1 Reactor Building Cooling System HEPA Filter Instrumentation Activation of this filtering system is initiated automatically by a safety injection signal (from the ESF actuation system) or by manual action at the main control board. A separate automatic initiation si gnal is supplied to each redundant train. Under accident conditions, the filter bypass dampers of bot h trains (4 units) receive a signal to automatically close, 1 preselected cooling unit in each train is automatically started in low speed.

Main control board switches are provided for each fan motor (high and low) and for the filter bypass damper of each r eactor building cooling unit.

Instrumentation used for monitoring the performance of this filter system including bypass damper position indication, is described in Section 6.2.2.5.2.

6.5-3 Reformatted Per Amendment 00-01 6.5.1.5.2 Control Ro om Emergency Filter Instrumentation Activation of the control room emergency filter system is initiated automatically by a safety injection signal, a high control room radiation signal (RM-A1), (see Section

12.2.4) or by manual action at the HVAC control board in the c ontrol room. Other elements of the control room ventilation syst em are operated in conjunction with this emergency filter system to carry out the air cleaning function.

In particular, the relief dampers and outside air supply dampers of t he control room ventilation system are automatically tripped closed by the signals lis ted above. HVAC control board switches are provided for each emergen cy filtering fan. The f an inlet and discharge dampers operate in conjunction with their respective fans.

The overall operation of the control room ventilation system is described in Section 9.4.1. Instrumentation used for monitoring the performance of this filter system, including fan and damper status indication, is described in Section 9.4.1.2.1.

6.5.1.5.3 Fuel Handling Building Charcoal Exhaust System Instrumentation The Fuel Handling Building charcoal exhaust system components (2 f ilter plenums, one exhaust fan) are in continuous operation during normal, shutdown and refueling periods. The ESF function of the fuel building charcoal exhaust system is only required during the movement of fuel in the spent fuel pool or during cra ne operation with loads over the pool. Instrumentation used for monitoring system performance, including fan and damper status indication, is described in Section 9.4.3.2.1.

98-01 6.5.1.6 Materials Filter materials employed in the ESF filter systems are discussed in Section 6.5.1.6.1 and 6.5.1.6.2. 6.5.1.6.1 Reactor Building Cooling System HEPA Filter Materials Each of four Reactor Building cooling system filter plenums incl udes 120 HEPA cells.

Cells are nominally 24 inches square by 12 inches deep. Cells include media of high strength, waterproof glass fiber without separ ators, high temperature silicon adhesive, metal cell sides and silicon rubber closed cell sponge gasketing. RN 08-009 6.5-4 Reformatted Per Amendment 00-01 6.5.1.6.2 Control Ro om Emergency Filter and Fuel Handling Building Charcoal Exhaust System Filter Materials Both of the control room emergency filter plenums contain 1 prefilter bank, each with 15 prefilter cells. Each of the 3 Fuel Handling Building charcoal exhaust system filter plenums contains 1 prefilter bank, each with 12 prefilter cells. The prefilters satisfy the requirements of an d are marked for Unde rwriters Standard UL-900 [2], Class I; and therefore, the radiolytic or pyrolytic decomposition products will not interfere with safe ESF operation.

00-01 Both of the control room emergency filter plenum s contain 2 ba nks of HEPA filters with 15 HEPA filters per bank. Ea ch of the Fuel Hand ling Building charcoal exhaust system filter plenums includes 2 banks of HEPA filters with 12 HEPA filters per bank. Each filter is 24 inches square by 12 inches deep and includes glass media. The HEPA filters satisfy the requirements of MIL-C-51068C, MIL-F-51079 and are qualified to Underwriters St andard UL-586

[3]; and therefore, the radiolytic or pyrolytic deco mposition products w ill not interfere with safe ESF operation.

The 2 control room emergency filter plenums and the 3 Fuel Handling Building charcoal exhaust system filter plenums are of the vertical bed design. The control room plenums contain 11 sections and th e Fuel Handling Building charcoal exhaust system plenums contain 8 sections. Media is impregnated, activated coconut shell charcoal which meets the requirements of Regulatory Guide 1.52, Revision 2.
