GIBBSSAR 3.6 Protection _Against Dynamic Effects _ Associated hith the Postylated Ruptur2 of PipiDS This section describes design bases and measures that have been used to ensure that the containment vessel and all essentiali 1 equipment inside or outside the containment, including components of the RCPB, ESF, and safety-related conponents, have been adequately protected against the effects of blowdown jets, reactive forces, and pipe whip resulting from postulated rupture of pipi 9 The criteria for protection against pipe whip within the containment conform to NRC Regulatory Guide 1. 46. ( d) The criteria for protection against pipe break outs'.de the containment conform to the guidelines contained in Branch Technical Positions APCSB-3-1 and MEB-3-1. (3)

The protection of safety-related structures, systems, and components against postulated piping failures in high- or moderate-energy fluid systems that operate during normal and upset plant conditions is ensured by the following: l 1

a. To the extent practicable, by separation or remote (h location from pipes subject to postulated ruptures

b. Where separation is not feasible, by isolation of the pipes subject to rupture

c. Where neither separation nor isolation is practicable, by an arrangement of pipe whip restraints and jet impingement barriers 3.6.1 Postulated Piping Failures in Fluid Systems Outside of Containment 3.6.1.1 Design Bases Any fluid system or piping run within the plant that, during normal operating plant conditions, has a maximun operating temperature exceeding 200 F or a maximun operating pressure exceeding 275 psig, or both, can be subject to a postulated pipe treak.

Any fluid system or piping run with normal operating conditions of 200 F or less and 275 psig or less can be subject to pipe cracks. The internal energy of the fluid in these systems is not sufficient to cause a pipe treak.

3.6-1 Amendment 1

The essential systems and components which are required to shutdown the reactor and mitigate the consequence of a postulated 6 pipe rupture outside containment as defined in Table 15.4-12 of FESAP 414 uill be protected following a postulated piping failure outside the containment.

a. High-Energy Fluid Systems 7 he high-energy fluid systems subject co pipe breaks outside the containment building are identified in Tabic 3.6-1.

7here are no safety-related systems, structures or components located in the turbine building. Rupture of pipes located inside the turbine building will only be considered for cases where the impact of a whipping pipe or jet impingement force could cause damage to a safety-related structure adjacent to the turbine building e.g. auxiliary building wall. In those cases, the structure will be designed to withstand the effects of a postulated pipe rupture of a high energy fluid system in the turbine building, employing the use of energy absorbing material (EAM) and/or suitable structures.

For Main Steam and Feedwater lines as shown on Figures 3.6-1a and y 3.6-1b between the containment isolation valves and containment penetrations, breaks will not be postulated when the piping meets the requirements of ETP MEE 3-1, otherwise protection is provided in accordance with Eranch Technical Position APCSB 3-1 for 9 satety-related systems, structures or components by use of barriers.

b. Moderate-Energy Fluid Systems The noderate-energy fluid systems which are considered for eventual postulated through-wall pipe cracks are described in s ubsections 3. 6.1. 2, b. and 3.6.1.2,c. l1 Moderate-energy systens which are located inside the turbine generator building are not included because there are no safety related structures, systems or conponents located inside thel 1 turbine building.

GIBBSSAR 6.2.2 Containment Heat Pemoval Systems A completely redundant containment spray system, designed to provide emergency containment heat removal in the event of a LCCA, is provided. This system, in conjiinction with the emergency core cooling system, removes thermal energy from the containment environment following a LOCA or a main stcar .ine break inside the containment to reduce the containment pressure and temperature. The containment ventilation system is not designed for continued operation during a design basis LCCA. The containment ventilation system is designed for normal plant operation; it is described in subsection 9.4.6. Major components of the containment spray system include the refueling water storage tank, containment spray pumps, spray headers, nozzles, and containment recirculation sumps. g By reducing the pressure differential between the containment and the environment and, therefore, reducing the driving force forl 9 leakage of fission products from the containment atmosphere, the containment sprays also help to limit of fsite radiation levels.

The containment spray system also provides an effective means of removing postaccident radiciodine from the containment atmosphere. The fission product removal function of the spray systems is described in subsection 6.5.2 6.2.2.1 Design Bases The containment heat removal systems are designed and tested in accordance with GDC 38, 39, 40, and 50 of 10CFP Part 50, Appendix A. The sources and amounts of energy that are taken 9 into consideration in sizing each heat removal system are described in subsection 6. 2.1.1.

The containment spray system can remove sufficient energy to maintain the pressure below the containnent design pressure, even in the event and either a single of a single active failure during injection phase active or passive failure during recirculation phase. The systems are supplied from separate Class 1E power buses, described in Section 8.3. No single failure can cause loss of more than half of the installed 9 200 percent-cooling capacity.

The containment spray system is designed to permit periodic determination of proper functioning to demonstrate system readiness. Routine testing is performed periodically to verify the operability of active containment spray system components.

6.2-23 Amendment 9

GIBBSSAR O

The containment spray system is seismic Category I and ANSI safety Class 2. I1 Containment spray system components are designed to remain operable in the post-DBA environment. (Qualification criteria l 9 are discussed in Section 3.11.)

The containment spray system is designed to withs'.and the dynamic ef fects associated with a pipe rupture in a high-energy system.

The containment recirculation sumps provide a source of spray wate- during the recirculation phase of the containment spray sytvem operation, The sumps are designed to promote mixing of 9 ECC and CS system fluids thus providing for sufficient heat remotal capacity to maintain containment pressure below the design value for all cases of postulated loss-of-coolant occurrences.

The containnent spray system is the only heat removal system used to cool the containment environment during postaccident conditions.

6.2.2.2 System Design The containment spray system (flow diagram on Figure 6.2-25) consists of two separate and independent 100-percent-capacity lll trains. Each train consists of one pump, spray ring headers, nozzles, valves, connecting piping, a common refueling water storage tank, and a common spray additive tank. Water from the refueling water storage tank is used for containment spray during 9 the initial phase of a LOCA. After the supply of water from the refueling water storage tank is exhausted, water is recirculated from the containnent recirculation sumps.

The containment spray system is designated as ANSI Safety Class 2 and designed as a seismic Category I syster. Component design paraneters are presented in Table 6.2-18. The codes and standards used as a basis for the design are given in Table 3.2-1. , ,

A failure analysis of all active components of the heat removal systems during the injection phase and all active and passive compcnents during the recirculation phase shows that the failure of any single component does not prevent the system from 6.2-24 Amendment 9 h

GIBBSSAR fulfilling its design function. (This analysis is summarized in Table 6.5-4.) l 1

The system design permits f unctional testing of the containment spray pumps at 100 percent flow and integrity testing of individual components. The active valves are periodically exercised to verify operability.

The following are discussed in protection system signals and setsubsection 6.5.2: 'he plant points that actuate the containment spray system; the time, following the worst possible accident, that the containment spray system is assumed to be fully operational; the delay times, following receipt of the system actuation signals, that are inherent in bringing the system into service; and the extent to which the containment spray system and system components are required to be remote manually operated from the main control room.

Tests and inspections performed on system components are discussed in subsection 6.5.2.4.

The mechanical components of the containment spray system are described in this subsection. The parts of the syetem in contact with borated water are stainless steel or an equivalent corrosion-resistant material.

There are four ring headers per train, physically located at different elevations at the uppermost part and supported from the containment dome. In addition, there are three headers per train 4 at lower floor elevations to ensure heat removal in subccrpartments that are enclosed.

The spray water flow path is as follows: water flows from the spray nozzles; falls through the containment atmosphere; washes the containment walls; passes through the operating floor grating; and washes down the reactor vessel head, steam gene rators, reactor coolant pumps and piping, primary shield walls, floors, and drains through floor drain systems, overflows the containment sump and thereby reaches the containment 9

recirculation sump.

6.2-26 Amendment 9

GIBBSSAR O

e. Contairment Recirculation Sumps l9 The containment recirculation sumps are enclosed by a protective 7

screen, as shown on Figure 6.2-27.

Redundant sumps are provided. The clogging of one sump does not prevent the redundant system from providing the required containment spray recirculation flow. The design of the sumps isl in accordance with Regulatory Guide 1.82. . 4 The sumps are located on the lovest floor elevation in the containment, exclusive of the reactor cavity. The sump intake is protected by an outer trash rack, a coarse screen, and a fine inner screen. The sump screens are not depressed below the floor elevation.

All floor drains from the upper regions of the containment terminate in the containment sump (leak detection sump) , thereby preventing direct streams of water, which may contain entrained 7 debr is , from impinging on the recirculation sump intake filter assentlies.

The trash rack is provided to prevent large debris from reaching the inner screens. The maximum design velocity of 0.2 ft/sec at llg thc coar se screen allows debris with a specific gravity of 1.05 4 or more to settle before reaching the fine screen. The available surface area used in determining the design coolant velocity is based on one-half of the free surface of the fine screen to conservatively account for partial blockage.

The trash rack and screens are designed to withstand the vibratory motion of the SSE without loss of structural integrity.

The fine screen is 7 resh, per linear inch, 0.041-inch wire.

This 0.102 inch square clear opening gives 51 percent open area. 4 The opening in the fine screen is based on the minimum clearance between grid assemblies and fuel rods in the reactor core.

in the recirculation sump is carefully l1 The pump intake design 7 established to prevent degrading ef fects such as vortexing on the pump performance.

Inse rvice inspection requirements for the sumps will include inspection of the trash racks, screens and pump suction inlet openings during every refueling outage. The inspection will be a visual examination of these areas for evidence of structural distress or corrosion.

6.2-27 Amendment 9 Ih

GIBBSSAR The screens are constructed from stainless steel or an equivalent resistant material to avoid degradation during pe riods of inactivity and to ensure compat8bility with the recirculated coolant. The containment sump collects the mixture of containment sprey and ECCS water; it is the only source of water for the ECCS and containment spray systems during the long-term core cooling and containment atmosphere cleanup period. To ensure that air binding of the ECCS pumps does not occur during the recirculation phase of a LOCA, the piping, from the containment recirculation sump to the first containment sump isolation valve, is arranged so that as water enters the line, 7 all air in the line is vented back into the containment.

Eoth containment recirculation sumps collect postaccident water spilled on the floor and overflowed from the containment sump at elevation 90 feet, 6 inches. If one recirculation sump is not '

operating, the other handles the total flow required to fulfill the minimum ESF functions.

Each containment recirculation sump is connected through separate suction pipes to one containment spray pump and one RHR pump.

Each suction pipe is inserted into a containment sleeve and creates, in conjunction with circular seals welded to both pipes, an extended containment barrier.

Since the contain.nent recirculation sumps are entirely within the containment subject and form part of the containment structure, they are to the same initial integrated leak rate testing at design pressure as the containment. Provisions are made in the 9 containment design to permit periodic leakage rate tests as discussed in subsection 6.2.6.1,C, to verify the contir ued leaktight integrity of the containment.

During post-LOCA conditions in the containment, particulate matter such as concrete, glass, metal chips, paint, and thermal insulation could be released. Some larger particles, such as wire or structural metal could fall into the recirculated water.

Paints and thermal insulation are selected for their resistance to post-LOCA containment environment, thus reducing the amount of debris collected in the sump area. The water entering the suction pipe may contain a small amount of particlea which have a l 9 diameter of less than 1/8 inch; it cannot clog the containment spray nozzles. (The diameter of each orifice is 3/8 inch, which 6.2-28 Amendment 9

GIBBSSAR is larger than the dianeter of the holes in the last series of screens in the containnent sump.)

During the recirculation phase, the containnent spray system can acconmodate snall quantities of debris, i.e, fragments of insulating materials, paint flakes or dust which may enter the suct ion lines.

Following a pipe rupture, parts of the component insulation will becone caslodged due to pipe severance or jet intercept or both. 6 Port ions of the dislodged insult. Lion will disintegrate while the remainder will stay structurally intact.

The disintegrated insulation, whether encapsulated mass-insulation or reflective insulation, will cre ce a potential 7 for strainer or drain line clogging.

Due to the weight of the insulation panels described below, dislodged but intact panels will not te carried or moved by the low-velocity drainage flow within the containment and are therefore not considered to present any further hazards to the containrcent recirculation system.

Analysis of the potential locations of the major pipe ruptures 6 where containment recirculation is required, indicates that all such locations are remote from the containment recirculation strainers. Further, the study indicates that there is no direct access between the break locations and the strainers.

Eith this arrangement, a large portion of the disintegrated insulation will becone trapped by the barriers created by gratings, piping, structures and other components, thereby ascertaining that the anount of insulation reaching the screens will be ninimized.

The four Main Steam lines are located above the operating deck on elevation 150'-11" and 171'-11" and have as such a potential for clogging the refueling canal drain, should a pipe break occur. 7 However, a large portion of these lines are shielded by the Steam g Generator Compartments and run an opposite sides of containment.l therehy limiting the direct access to the refueling canal,l 7 Fedundant drains are installed in the refueling canal as shown in g Figure 6. 2-35.

6.2-29 Amendment 9

GIBBSSAR The feedwater lines are all routed above the operating deck at elevation 1248-6", thereby ensuring that the insulation will not 6 reach the Refueling Canal. The line routing further provides a 6.2-29a Amendment 7

6.5.2 Containment Spray System The containment spray system has, in addition to its heat removal 1 capabilities, the ability to scrub fission product from the post accident atmosphere of containment and to minimize the release of radioactive iodine to the environment. This section describes the iodine removal capability of the containment spray system and the analysis of the radiological consequences of the LOCA is lll given in Subsection 15.6.5.3.

6.5.2.1 Design Bases Following a loss of coolant accident, the release of radioactive iodine isctope (Cee Table 6.5-2) from the reactor con ainment will present a hazardous condition which will be alleviated by the containment spray system and will reduce the offsite doses well below the limits of 10 CFR Part 100. The sodium hydroxide solution is added to the borated spray water via a spray additive subsystem. Component sizing, layout, and the spray solution chemistry will be gcverned by the f ollowing principal criteria:

~

a. Nolumetric containment coverage, with one out of two redundant spray trains in operation, must be maximum.

b. The spray fall height above the operating floor used in the analysis was conservatively taken as the difference in elevaticn between the lowest ring header of the containment 9 dome and the operation floor. This distance is 140 feet.

1 6.5-4 Amendment 9

GIBBSSAR

c. The spray system will deliver the design flow rate of 1 4500 GPM, to one train of spray nozzles, despite a single 9 failure in the containment spray system.

1

d. The system will be capable of permanent removal of iodine from the containment atmosphere by absorption into the spray droplets and retention in the containment recirculation sump. l9

e. Components of the containment spray system as well as the spray additive subsystem will be designed to meet safety Class 2 and seismic Category I requirements.

6.5.2.2 System Design (for Fission Product Pemoval) t One of the containment spray system functions is fission product iodine removal from the containment atmosphere during the initial mode (injection phase) of system operation. This phase is initiated automatically by a containment pressure HI-3 signal, by manual action or by safety injection signal coincident with a HI containment temperat +e signal. Generation of the HI-3 signal is described in subsection 7.3.1.1.a. These signals will automatically open the discharge valves to the spray headers 9 which can also be opened manually from *ue control room. Prior to the containment spray actuation signal, the containment spray pumps will have received a signal to start from the safety injection "S" signal.

At this time each containment spray pump draws water from the Refueling Water Storage Tank. The quantity of water in the EWST is sufficient enough to provide water to both the containment spray system and emergency core cooling sy stem. Simultaneously with the start of the injection phase the valves of the spray cdditive tank discharge open to allow the flow of NaOH, which is drawn from the tank and is introduced by eductors into i containment spray pump suction pipe.

The spray additive tank outlet valves are closed during normal operation to prevent mixing of the NaOH with boric acid in the RWST. The REST is adequately vented to permit rapid drawdown.

Nitrogen gas cover inside the spray additive tank is provided by the nitrogen supply to ensure an adequate pressure inside the tank. Approximately 5 percent of each containment spray pump flow is branched through the pump bypass eductors, to draw sodium hydroxide from the spray additive tank and this flow is returned back to the pump suction line.

6.5-5 Amendment 9

GIBBSSAR g

A 30 pcreent by weight :olution of sodium hydroxide flow will bei l calibrated at 85 gpm per eductor to maintain the alkalinity ofl 9 the spray solution at the design pH range of 9.3-10.0. This l1 9

6.5-Sa Amendment 9

GIBBSSAR alkalinity will be maintained in this range during the entire injection phase.

The containment spray additive subsystem is composed of one spray additive tank, two chemical eductors, connecting piping, valves, and related instrumentation. The containment spray system is capable of delivering spray water to the containment atmosphere in sufficient quantity and with an optimum average droplet diameter to ensure adequate iodine removal from the contalnment atmosphere. The spray system is comprised of two independent trains each containing one spray pump, piping, spray headers, valving, spray nozzles and associated instrumentation. There are four ring headers per train, physically located at different elevations at the uppermost part and supported from the containment dome, and three auxiliary headers located at lower elevations to maximize sprayed volume coverage. All containment sp ay headers are equipped with- nozzles each spraying hoilzontally, vertically downward, upward at 45 degrees and 1 downward at 45 degrees. This arrangement provides a maximum volune spray coverage even if one of the containment spray trains fails to operate. The number of spray nozzles is based cn sprayed volumes required for each containment region and their respective flow rates as listed in Table 6.5-3. The nozzles are of a hollow type with 3/8 inch diameter orifice and designed to operate at a pressure drop of 40 psi. These nozzles produce droplets with a mean diameter less than 1000 microns at 40 psi differential pressure.

The nozzle spacing and orientation provides t ximum coverage of containment volume. The physical arrangement is shown in Figure 6. 5- 2. The histogram of the observed dropsize frequency is based on tests performed by Spray Engineering laboratory of the Spray Engineering Company's spray Company'sl nozzle type 1713a as shown in Figure 6.5-3. 19 In case of a LOCA and loss of offsite power, the maximum time to close containment spray pump breakers, including 10 seconds for a 1 diesel generator to come up to speed and voltage, will be 20 seconds after the safety injection signal actuation. The safety injection signal is actuated within the first second following the accident. The containment analysis will use value of 51.3 seconds for delivery through all spray nozzlesthe of at least the one train at rated flow due to the delay outlined below, 9 after double-ended reactor coolant pump suction pipe guillotine break and loss of offsite power.

1 6.5-6 Amendment 9

GIBBSSAR O

This delay includes:

a. Within the first second after the break, the safety' injection, "S" signal, is actuated.

b. Seven seconds after the break, the "P" signal is activated at 20 psig containment pressure.

c. Eleven seconds after the break, the opening of the containment spray pump isolation valves is initiated.

d. Twenty-one seconds after the break the containment spray 9 pump will be started, and the containment spray pump isolation valves will be fully open.

e. Twenty-six seconds after the break, the containment spray pump will be at full speed.

Between the 26th and 51st second, water will fill the CS piping and full flow or ':he f urthermost nozzle uill he achieved.

Duration of the injection phase of the containment spray flow depends on the total flow drawn from the RWSI at the flow rates required of the ECCS and containment spray system. This duration i.e.,

{lg is given in Table 6.1-6 for all modes of operation, combinations of maximum or minimum ECCS operation with one or two train containment spray system operation.

The suction of the containment spray pump will be automatically 1 switched to the recirculation sumps when the REST supply is nearly exhausted, that is, when its contents are reduced to 70,000 gallons. The automatic recirculation signal, described in subsection 7.3.1.1.b, will start the recirculation phase of the containment spray system, opening the motor operated valves in the suction lines from the containment recirculation sumps, where the injection water, reactor coolant and accumulator spillage 9 have collected. Af ter the ~ start of the recirculation phase, the motor operated valves from the REST will be automatically closed, isolating the RWST from the containment spray pumps. Water from the sumps will then be sprayed into the containment. The sumps are designed to promote continuous mixing of ECC and CS systems water, thus providing sufficient heat removal capacity to maintain containment pressure below the design value for all cases of postulated loss-of-coolant occurrences. Failure to switch a spray train at the RWST low level will be automatically detected by the low-low RWST water level which will be annunciated in the control room. At this time the control room 6.5-7 Amendment 9 llh

GIBBSSAR operator will manually switch the affected containment spray train to start the recirculation phase. This phase of operation will continue as long as necessary to ensure containment 9 depressurization.

6.5-7a Amendment 9

6. 5. 2. 3 Design Evaluation The containnent spray additive subsystem uses state-of-the-art technology for absorbing radioactive iodine from the containment l4 atmosphere. A favorable alkalinity level is established by the addition of sodium hydroxide solution to the spray water. The alkalinity increases the solubility of iodine so that the rate of 1 iodine absorption is limited mainly by the mass transfer rate through the gas film surrounding the spray water droplets.

Furthermore, the alakalinity level is such that it prevents the.

dissolved iodine from escaping from the containment recirculation 9 sump water.

Radiciodine, in its various forms, is the fission product of primary concern in the evaluation of a LOCA. The major benefit of the containment spray is its capacity to absorb elemental iodine from the containment atmosphere. To enhance iodine-absorption capacity of the spray, the spray solutionthe is adjusted to an alkaline pH which promotes iodine hydrolysis to 1 nonvolatile forms.

According to the known behavior of elemental iodine in highly dilute solutions, the hydrolysis reaction I + CH' "HIO + I~

2 6.5-9 Amendment 5

GIBBSSAR h

is nearly completed at ph>8. The iodine form is highly soluble, and HIO readily undergoes additional reactions to form iodate.

The overall reaction is 3I + 3H O , '5HI + HIO 2 2 3 1

The basic criteria used for design of the spray additive subsystem are explained as follows:

a. Alkalinity level of the spray solution during the injection phase is pH=10.5 for all modes of operation (fully ef fective spray and minimum safeguard operation) .

b. Volume of NaOH drawn from the spray additive tank during the injection phase is such that the final sump alkalinity is pH=8.6 (fully ef fective spray and minimum ECCS operation) .

The containment sump solution pH for each operational mode is given in Table 6.1-6, taking into consideration a single failure analysis. The single failure analysis for the spray additive subsystem is shown in Table 6.5-4.

O To determine the containment recirculation sump solution pH, all sources of borated water such as the RCS accumulators, the boron injection, the refueling water storage tank, and the weight of NaOH which would be lost in the containment " dead" volumes are taken into consideration. The " dead" volumes consist of the reactor cavity up to RCS piping, cc4ntainment (leak detection) sumps and areas below the recirculation sump as incore instrumentation and RC drain tank rooms. Significant quantities 9 of spray and injection water will not be trapped in SG subcompartments because vent paths allow for drainage. Escape of the post-LOCA water from the containment sunp into a low activity waste collection tank will be precluded by drain isolation valves and by deenergizina the sump pumps after the accident.

The mixing of the containment spray solution with the spilled water is considered complete in the containment sumps. Material compatibility is discussed in subsection 6.5.2.6.

6.5-10 Amendment 9

GIBBSSAR The analytical method used for determining the effectiveness of the sprays is taken from WASH-1329, "A Feview of Mathematical Models For Predicting Spray Removal of Fission Products in Peactor Containment Vessels"(1) as recommended in SRP 6.5.2. The assumptions used are explained below:

1) The removal mechanisms are assumed to be first order and independent of time and iodine concentration. SRP 6.5.2. 4 III.4.b states that iodine removal is to be assumed to be first order. To be independent of iodine concentration, the physical properties such as density, viscosity, and diffusivity as well as the partition factor, H, must be independent of iodine concentration. At low iodine concentrations, the physical properties are known to be independent of iodine concentration, however H is not (1).

6.5.2.4 Tests and Inspections The containment spray system will be designed to permit periodic testing to demonstrate system performance readiness. Each component of the system shall be subjected to preoperational, and operational testing andtoinspections as described in the following paragraphs. In addition routine inspection, periodic visual inspections will be 1 performed to check for corrosion and surface cracks in welds.

a. Preoperational Inspection and Testing Containment spray components will be inspected and tested in accordance with applicable codes as described in Section 3.2.

The environmental conditions for qualification tests are shown in Tables 3.17-1 and 3.11-4 and Figures 3.11-1 and 3.11-2. g The containment spray pumps will after installation to ensure be tested after fabrication and full operability and required performance. The performance curves and NPSH requirements will be supplied by shop tests to confirm pump design characteristics. After installation the pumps will be tested using refueling water by recirculating back to the RWST. This test will also check and verify the operability of the recirculation flow control valves. 1 The spray additive be eductors will tested and calibrated after fabrication addi tive for their solution.

performance using fluid comparable to the spray After installation, the spray additive system will be tested using refueling water as the test fluid. For evaluation of test data results, a correlation factor of 1.34 will be used (ratio of specific gravity of the NaCH solution to borated water) .

To verify maximum droplet mean diameter for spray nozzles, performance data will be provided after the manufacturer's shoptest.

6.5-17 Amendment 9

The spray nozzles will not be tested "in situ" with water. However, a containment spray system full flow ring header test was performed at Zion Nuclear Power Plants - Units 1 and 2 (Docket Numbers 50-295 and 50-304) . This test demonstrated that flow passing through the system was as designed, that there was no discernable movement in the ring headers when subjected to spray flow forces, and tha t the containment coverage was as predicted. After the spray headers are installed, air under pressure will be passed through test connections in order to check that the spray nozzles and ring headers are free of obstructions and are not clogged.

b. Operational Testing Poutine testing will be perforned periodically to verify the operability of active containment spray system components.

1) The spray additive system will be tested using refueling water as a test fluid. The test line from the RWS1 to the spray additive discharge line, upstream of the spray additive flow measuring element will be opened, along with the full flow test line from the discharge of the containment spray pumps which is recirculated back to the RWST. For evaluation of test data, the correlation factor is 1.34 (ratio of specific gravity of the NaOH solution and lh borated water).

2) Sequencing of valves and pumps will be tested by shutting the manual valve on the containment spray line inside the containment and the manual valve on the chemical l9 additive supply line and triggering a simulated actuation.

signal. All automatic valves and the pumps will be checked for proper sequencing.

3) Each pump will be run at full flow with the flow directed back to the RWST.

4) Spray nozzles will be tested by compressed air using test connections in the containment spray lines to check the spray nozzles for flow. Operators will confirm that all nozzles are free of costructions.

5) The RWST water is sampled periodically to monitor water chemistry. Provisions are made so that the water can be purified by circulating it through the purification loop of the spent fuel pool cooling and rurification system.

6) To maintain an adequate supply and proper concentration 1 of NaOH in the spray additive tank, both the fluid level and the NaOH concentration will be checked usually once a month and once a year, respectively.

7) Means will be provided for intermittent detection of a RWST and CSS particulate material which could plug the spray ~

nozzles. The testing will be performed periodically using the test line returning water to the RWST. The discharge into the tank will be divided into two fractions, one for the major portion of the flow and the other to pass a quantity of water through test nozzles, identical withsmall the containment spray nozzles. This assures that there is no 9 particulate material in the RWST and CSS.

The flow rate through the test nozzles will be monitored and compared to the previously nozzles.

The degree of. cQmpliance with each of these safety criteria is as outlined below.

7.1- 4 Amendment 9

GIBBSSAR

a. NPC Pequlatory Guide __1.11, "IDatrument Lines P_enetrgging Primary _ Reactor _Qgntaingent" The only instrument lines that penetrate the Primary Peactor Containment are for the reactor containment pressure transmitters, and these are designed in strict conformance with 9 subsection 6.2.4.1. l The following paragraph numbers correspond to like numbered paragraphs in Pegulatory Guide 1.11, and are presented to indicate the degree of compliance to this criteria.

c.1a There are four separate and independent pressure sensing lines, each of which can be tested individually.

C.1b Sensing lines are 0.25" O.D., 316 SS with 304 SS flexarmor and are leaktight, hence, no makeup or offsite doaes are expected.

C.1c The reactor containment pressure sensing lines do not have isolation valves. Isolation is provided by means of double sealed bellows 1 connected to a fluid-filled tube, thus protecting (in the case of line break inside or outside of containment) against leakage of the containment atmospnere.

C.1d Instrument lines are conservatively designed and of a quality at least equivalent to the containment and subject to strict quality control and regular inspections to assure integrity. Instrument lines will be located and protected so as to minimize the possibility of their being damaged accidentally and also to permit periodic visual inservice inspection, particularly outside containment. They will be protected or separated to prevent failure of one line from inducing failure of any other line.

C.2 The non-safety-related, systems or components whose failure would unacceptably reduce the 7.1-6 Amendment 1

GIBBSSAR The redundancy requirement for the isolation of the lines penetrating the containment is satisfied by having two isolation valves in series. In this case, the power 6 supply for the valves comes from separate and independent buses, i.e. , one valve is powered from the Train A bus, and the other valve is powered from the Train B Bus.

4) Control Room Indication Each remotely operated containment isolation valve is provided with limit switches to give control room indication of valve status,

b. Containment spray Systen The containment spray system is outlined in detail in subsection 6.5.2. 1 Il Actuation of System Components The containment spray system consists of two separate and independent full-capacity safety-related loops, each 6 Cdpable of fulfilling the design requirements. The system is initiated automatically by a HI-3 signal by manual action or by safety injection signal coincident with a Hi containment temperature signal. Generation of 9 this HI-3 signal is described in subsection 7.3.1.1,a.

Manual initiation of containment spray is accomplished by actuating either of two sets of switches (two switches per set.) Both switches in a set must be actuated to obtain a manually initiated spray signal.

The sets are wired to meet separation and single-failure requirements of IEEE 279. Simultaneous operation of two switches is desirab1<. to prevent inadvertent spray actuation.

Prior to the containment spray actuation signal, the containment spray pumps have been started by safety injection signal S.

9 Receipt of the HI-3 or safety injectio3. signal concident with a Hi containment temperature signal initiates the following automatic action: the opening of the spray header discharge valves; and the opening of the chemical additive tank stop valves. -

The Potable and Sanitary Water System (subsection 9. 2.4) , the Ultimate Heat Sink (subsection 9.2. 5) , and the Water Treatment System (subsection 9.2.7) will be described in the Utility-Applicant's SAR.

9.2.1 Station Service Water System 9.2.1.1 Design Bases The service water system removes heat from the ccmponent coolia water heat exchangers and, depending on the quality of site water available, certain other plant components. The service water system also acts as an alternate safety class water source to the auxiliary feedwater system, which is described in subsection 10.4.9. and an alternate NNS Seismic Category I water source to the fire protection system. The service water system supplies cooling water to meet the cooling requirements listed in 9 Table 9.2-1 and Table 9.2-2 during normal operation, shutdown, and during and after a postulated.. accident or loss of offsite power.

The choice of the service water system (once-through or closed cycle) is a function of the available ultimate heat sink (subsection 9.2.5) which is site-related, and will be presented in the Utility-Applicant's SAR. Freeze icing and other adverse environmental conditions protection which is site-related, will 6 be presented in the Utility-Applicant 8s SAP. See Table 9.2-5.

GIBBSSAF The service water syr,tt m is designed to accommoda te a range of inlet water design temperatures, i.e., 85 F, 95 F, and 100 F.

The service water design flow rate is established for the most stringent operating conditions. The component cooling water heat exchangers are resized to maintain the same heat exchange capacity over the whole temperature range with a constant service water ficw rate. The service water system design parameters presented in Table 9.2-3 are based on the. previously mentioned criteria and on cooling the component cooling water heat exchangers and emergency diesel generators,which are required to operate af ter a LOCA, and the nonessential CVCS chiller package.

However, for those sites where water quality is unacceptable, the service water system cools only the component cooling water heat exchangers. Service water system design parameters presented in Table 9.2-3 will be ammended to reflect the different flow conditions.

The service water system functions during normal operation and during and after a postulated accident or loss of offsite power.l9 Equipnent required for safe shutdown is included on two identical redundant loops, the essential cooling loops. Flow in each essential loop is supplied by pumps powered from the emergency buse s. Separate and independent emergency diesel generators supply power in the event of loss of primary and alternate offsite power. The onsite emergency power system is described in Section 8.3. The two essential loops are physically separated from each other and can be automatically or manually isolated.

The CVCS chiller unit is cooled on a nonessential loop, which can be automatically or manually isolated from the two essential loops.

The two essential service water loops are designated Safety Class 3 and in accordance with the ASME ESPV Code, The system is Seismic Category I and is protected Section III.

against the effects of a tornado.

9.2.1.2 System Description The service water system is shcwn in Figure 9.2-1, and consists of two separate and independent, full-capacity essential loops and one nonessential loop. Each of the essential loops is equipped with two 100 percent-capacity service water pumps which feed one component cooling water heat exchanger and one emergency diesel generator. The nonessential loop, which contains the CVCS chiller unit, can be supplied by the pumps of either essential loop supply to the fire protection system is provided 9 from the discharge of each loop to the ultimate heat sink.

9.2-2 Amendment 9

GIBBSSAR O

Under normal operation, a single service water pump supplying water to a component cooling water heat exchanger, emergency l 9 diesel generator of the same essential icop, and to the CVCS chiller unit cn the nonessential loop is adequate for normal plant operation. Should the operating service water pump trip, the second service water pump in the operating essential loop autonatically starts. In the unlikely event of a fault occurring in the operating essential loop, instrunentation logic is provided to automatically transfer operation to the other 9 essential loop. If system operation is transferred from one essential loop to the other, feed to the nonessential loop is realigned to the operating essential loop. In the event that one service water pump is taken out of service for naintenance, the second f ull-capacity punp in the name essential loop is available for service.

For normal cooldown, the service water system uses two service water pumps (one from each essential loop) to supply both compcnent cocling water heat exchangers, energency diesel generators, and the CVCS chiller unit. A slower but acceptable cooldown rate may also be accomplished with only one service water pump supplying water to one component cooling water heat exchanger, an energency diesel generator, and to the CVCS chiller unit. g Under accident conditions on receipt of an S signal, a pung in the second essential locp is started so that cooling water is supplied to both component cooling water heat exchangers and both energency diesel generators. Upon receipt of the containment isolation signal, Phase B, the nonessential loop is automatically isolated from the essential loops. Although only one essential loop is required to mitigate the consequence of an accident, ccoling water continues to be supplied to both essential loops.

A single failure of any component does not prevent the service water system from supplying water to one essential loop, as described in Table 9.2-4.

Chemical addition to the service water to protect system compcnents against corrosion depends on the water qua lity, the components to be cooled, and the nature of the service water system cycle. Corrosion protection of the service water systen is site-related and will be discussed in the Utility-Applicant's SAR. The effects of water level, sedinentation, and other environmental related effects are site-related and will also be discussed in the Utility-Applicant's SAP.

9.2-3 Amendment 9 lh

GIBBSSAR Flow indication is provided downstream of each of the components cooled by the service water system to detect abnormalities in the system flow rates. Abnormal flow conditions are annunciated in the control room. The detection of leakage through the component cooling water heat exchangers to the CCES is discussed in subsection 9.2.2.2. Although no radiation contamination of the service water system is anticipated, a radiation monitoring system is provided to ensure that any contamination will be detected.

9.2.1.3 Safety Evaluation The service water system is made up of two full-capacity essential loops and one nonessential loop. During emergency operation, the nonessential loop is automatically isolated from the essential loops. The two essential loops are separated each other by two remotely operated valves in series. from The essential loops are redundant in that the component cooling water heat exchanger and emergency diesel generator supplied with cooling water by one loop are sufficient to perform the minimum required safeguard function. Failure of the nonessential cooling loop has no adverse affect on the capability to safely shutdown the plant or to maintain the plant in a safe shutdown condition.

The performance of all components is monitored from the control room. Low flow, low pressure, high temperature, and high radiation level, all of which are indicative of system malfunction, are annunciated in the control room. Radioactive contamination of the service water system is not expected; however, a radiation monitoring system is provided to ensure that any contamination is detected. The radiation monitoring system is described in Section 11.5 The essential Seismic Category I service water loops of the system are designated ano _afety Class 3. The essential plant components cooled by the service water system are located in separate areas of the ESF area, which is inside the seismic Category I auxiliary building. At the interface between the service water system and the ultimate heat sink, the service water pumps are protected by a semisic Category I structure designed to withstand the possible effects of flooding. This building is site-related and will be describedand tornadoes in the Utility-Applicant's SAR. The piping from the service pump discharge is buried underground. water The piping and all supports are designed to Seismic Category I requirements. The amount of earth cover is sufficient to protect the piping from tornado generated missiles. These conditions together with the

9. 2- 4

GIBPSSAR classificaticn of the service water system as Seismic Category I ensure that the systen is capable of withet anding adverse environmental occurrences such as postulated earthquakes, tornadoes, and tornado-generated missiles. The non -

essential loop is classified NNS and is Seismic Category I.

The physical separation of the two essential loops precludes coincident dairage to redundant equipment in the event of a post ulated pipe rupture, equipment failure, or missile generation. Protection against dynamic effects associated with the postulated rupture of piping are discussed in Section 3.6.

9.2.1.4 Tests and Inspections Components in operation will te alternated periodically to enable testing and inspection. The standby components will he inspected g to find and correct incipient malfunctions. Sufficient instrumentation is provided to monitor system performance.

The service water components are positioned to allow access for g periodic examinations as required by the ASME ESPV Code.

9.2.1.5 Instrumentation A detailed descripticia of the instrumentation provided for the 9

service water system is included in subsection 7.3.1.

9 . 2.1. 6 Interface Requirements for the service water system are described in Table 9.2-5 9.2.2 Component Cooling Kater System 9.2.2.1 Cesign Bases The component cooling water sys ten. provides an intermediate barrier between those radioactive or potentially radioactive system couponents requiring cooling and the service water system.

The CCWS, a closed-loop system, is designed to perform the follcwing functions: to remove residual heat from the RCS via the FHR syctem during plant cooldown; to cool the letdown flow to the CVCS during normal operation; to cool ESF heat loads after an accident; and to dissipate heat rejected f rom various plant l 9 components in a manner that precludes direct leakage of radioactive fluids to the ultimate heat sink. The heat loads and 9.2-5 Amendment 9 lh

GIBBSSAR lll flow rates required to perform these various functions are listed in Tables 9.2-6 and 9.2-7.

The CCWS is designed to accommodate a range of inlet service water design temperature, i.e., 85 F, 95 F, and 100 F. The CCWS flow rates are established by the cooling requirements of plant compcnents under various operating modes. The CCHS heat exchangers are resized for each service water design temperature to maintain the same heat exchange capacity with a constant service water flow rate (subsection 9. 2.1) . The CCWS provides cooling water in sufficient quantity and within the temperature limits of 105 F during nornal plant operation and 120 F during reactor cooldown or after a postulated LOCA. With this design, three CCHS heat exchanger sizes, which become progressively smaller as the inlet service water decign temperature is reduced, are used. The largest heat exchanger design is used for the purpcse of space allocation within the ESF area. The CCHS design paraneters presented in Table 9.2-8 are based on the forementioned criteria and on cooling the various plant components listed in subsection 9.2.2.2.

The CCWS is required to function during normal operation and during and after a postulated LOCA. Equipment required for safe shutdown is included on two identical redundant loops, the essential cooling loops. Flow in each essential loop is supplied by ptmps powered from the emergency buses. Separate and independent emergency diesel generators supply power in the event of loss of primary and alternate offsite power. The onsite emergency power system is described in Section 8.3. The remaining plant components are cooled on a nonessential loop.

The two essential loops are physically separated from each other and can te automatically or manually isolated.

The CCWS is maintained at a higher pressure than the service water system to prevent leakage of the untreated service water which may contain impurities. This protects certain plant components cooled by the CCHS against possible chloride-induced stress corrosion.

The two essential loops of the system are designated safety Class 3 and in accordance with the ASME ESPV Code,Section III. All non-nuclear safety-related portions of the loop can te remotely isolated from the control room. The safety Class 3 portien of the loop is seismic Category I and protected 9 against the effects of tornado. The nonessential loop is classified NNS and is Seismic Category I.

9.2.2.2 Systen Description The two essential loops of the CCES are shown on Figure 9.2-2; the portion of the nonessential loop outside of the containment is shown on Figure 9.2-3; the portion inside containment is shown on Figure 9.2-4.

The CCES consists of two separate and independent, full-capacity essential loops and one nonessential loop. Each of the ersential loops is equipped with two 100-percent capacity CCES pumps and one CCWS heat exchanger. The nonessential loop may to supplied by the pumps and heat exchanger of either essential loop.

All the components required to he cooled following a LOCA are included in each of the essential loops. The following is a comprehensive list of the components included on each loop:

a. CCW pump cooler i4

t. PHP heat exchanger

c. Containment spray pump cooler

d. FHF/ low-head safety injection (LHSI) pump ccoler 9 lll

e. Auxiliary feedwater pump ccoler

f. Centrifugal charging pump cooler

g. Safeguard chilled water system

h. Spent fuel pool heat exchanger The above components, except the spent tuel pool heat exchanger, are required to operate following a LCCA. The spent fuel heat exchangers are isolated after a LCCA on a phase E containment isolation signal, but they are included in the essential loops so that they may receive cooling water. ten hours later to prevent toiling of the spent fuel pool. The above is a complete list for 9 those sites with acceptable quality water available for use in the service water system. On sites with unsuitable quality water, the energency diesel generators will be cooled by the essential loops of the CCES and the size of the CCW heat exchangers will te increased accordingly. The essential loops are redundant in that the 9.2-7 Amendment 9 h

GIBBSSAR conponents supplied with cooling water by one loop are sufficient to perform the required safeguard functions. They are separated from each other by at least two valves at any interconnection.

'The remaining components requiring cooling water are included on the nonessential loop. Components cooled by the nonessential loop external to the containment are as follows:

a. Health physicist office and service area air conditioning 4

b. Instrument and service air aftercooler and compressor

c. Process sample heat exchangers

d. Becycle evaporator package

e. High activity waste evaporator package

f. Low activity waste evaporator package

9.2-8a Amendment 9

GIBBSSAR Under normal operation, a single CCES pump and single CCWS heat exchanger of the same essential loop are adequate for normal plant operation. If the operating CCWS pump trips, the second CCWS pump in the operating essential loop automatically starts. 9 In the unlikely event of a fault occuring in the operating essential loop instrumentation, logic is provided toi automatically transfer operation to a punp and heat exchanger of the other essential loop. If one CChs pump is taken out of service for naintenance, the second full-capacity pump in the same essential loop is available for service. Cooling water is normally supplied through the operating heat exchanger to both essential loops and to the nonessential loop; however, only one spent fuel pool heat exchanger is required for normal operation.

To facilitate cooldown, the CCES uses two CCHS pumps and two CCMS heat exchangers to supply cooling water to both essential loops and the nonessential loop. A slower but acceptable cooldown rate may be accomplished with only one CCES pump and one CCWS heat exchanger aligned to one essential loop and the nonersential loop. Under both conditions, the maximum component cooling water temperature at the CCW heat exchanger outlet is 120 F for a maximum period of 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months , after which the temperature gradually returns to 105 F.

Under accident conditions, on receipt of an S signal, a pump in the other essential loop is started and flow from two pumps is supplied to all loops. Upon receipt of the containment isolation signal, Phase B, the nonessential loop is automatically isolated from the rest of the system, and the two e' Jential loops are isolated from each other. Although only one essential loop is required to mitigate the consequences of an accident, component cooling water is supplied to both essential loops. A single 9 failure of any component does not prevent the system fron supplying water to one essential loop, as described in Table 9.2-9.

A partitioned surge tank, vented to atmosphere, accommodates surges resulting from component cooling water thermal expansion and contraction, and it collects any water that may leak into the system from components being cooled. The CCWS surge tank is located at elevation 167 feet, 6 inches which assures proper operation of the CCES pumps. A drop or rise in the surge tank level during steady operation indicates leakages within the 9.2-9 Amendment 9

GIEBSSAR system. The surge tank level is indicated both locally and in the control rocm, where high and low levels are annunciated.

One chemical addition tank is supplied. Upon detection of 4 in-leakage, manual adjustments are nade at the component cooling surge tank, until dissolved solids and corrosion inhibitor design concentrations as specified in RESAR-414 Section 1.7.1. are achieved. 9 Makeup water is normally delivered to the surge tank from the demineralized water P*orage tank or the reactor makeup water storage tank, with automatic operation of the tank level control valves. Under emergency conditions, makeup water can be supplied 9 from the seismic Category I portion of the fire protection system. See subsection 9.2.3 and 9.5.1 and Figures 9.2-6 and 9.5-1A.

Radiation detectors monitor the CCWS. If the radiation level of the cooling water exceeds a predetermined value, an alarm is given in the control room and the vent on the CCWS surge tank is automatically closed. A vacuum breaker and a relief valve are provided to protect the surge tank.

9.2.2.3 Safety Evaluation The CCWS is comprised of two full-capacity essential loops and one nonessential loop. During emergency operation, the nonessential loop is automatically isolated from the essential loops. The two loops are separated from each other by two autogatically operated valves. The failure of the nonessential cooling loop has no adverse affect on plant capability to safely shutdown the plant or maintain the condition. plant in a safe shutdown' 9 Cne branch of the noncesential loop supplies a header which penetrates the reactor containment and supplies the reactor coolant pumps with the required cooling water.

Each containment penetration is safety Class 2 and has an automatic isolation valve, position indicator and manual operator, located with! 9 outside the containment. One check valve is provided on the CCWS supply line inside the containment to prevent reverse flow, in case of a pipe rupture. CCW piping between the RC pump thermal barrier and the outer containment isolation valve is designed for full RC loop pressure and temperature.

GIBBSSAR g

The performance of all conponents is monitored from the control room. Low flow, low pressure, high ten pe ratu re , and high radiation level, which are all indicative of system malfunctions, are annunciated in the control room.

Leakage from any system being cooled by the CCKS is detected by an increase in the level of the CCWS surge tank or by an increase in the system radiation level, when the system being cooled is contaminated. Details of the radiation-monitoring equipment are given in Section 11.5. Leakage from the CCWS to the service water systen or to the atmosphere is detected by a decrease in the CCES surge tank level.

A partition in the surge tank provides separate surge volumes for each essential loop. If one essential loop develops a leak and is taken out of service, the operation of the other loop is unaffected. If a leak develops in the nonessential loop, it can be isolated from the essential loops and operation is unaffected.

The partition is designed to maintain its integrity while one side of the surge tank is empty. All components of the CCWS are located inside of a Seismic Category 1 structure. The CCWS pumps, the heat exchangers, and the essential loops are in the ESF area. The components of the two essential loops are physically separated within the ESF area by a dividing structure. 9 The CCWS pumps are located at elevation 94 feet, 6 incnes, which is above the flooding level that can occur due to equipment failure within the building. These conditions, together with the classification of the CCWS as Seismic Category I, make the systen capable of withstanding adverse environmental occurrences such as postulated earthquakes, tornadoes, and tornado generated wissiles.

The physical separation of the two essential locps precludes coincident damage to redundant equipment in the event of a postulated pipe rupture, equipment failure, or missile generation. Protection against dynamic effects associated with the postulated rupture of piping are discussed in Section 3.6.

9.2.2.4 Tests and Inapections Periodic chemical exanination of the conponent cooling water is nade for pH, chloride content, and corrosion inhibitor content; if required, manual adjustment is made utilizing the chemical addition tank to meet the Westinghouse chemistry specifications 6 listed in PESAR-414 Section 1. 7 .1. Periodic visual inspection and preventive maintenance can be conducted as necessary without interruption of cooling system operation.

The CCES components are positioned to allow access for periodic 1 examinations as required by the ASME Code.

The integegrity of the partition in the surge tank will be deternined periodically by raising the water level in one section of the tank to the high water level and observing if there is an 6 equalization of the levels. An equalizing of the levels would be indicative of a leak in the partition.

Two reactor makeup water pumps take suction from the reactor makeup water storage tank and these pumps discharge through a system of headers. As a minimum, one reactor makeup pump operates continuously. The system (including tanks, pumps, connections to the boric acid blender, the pressurizer relief tank, and the conponent cooling water surge tank) 9 is designed as non-Seismic Category I.

The water flow rate provided by the chillers is monitored and controlled and is contingent on the temperature of the air entering the cooling coil in each area being served. Automatically operated to the equipment 3 valves regulate the ficw of chilled water cooling the specified areas. The temperature of the chilled water is monitored, and kept constant.

GIBBSSAR A recirculation line fitted with valves, flow meter, and a differential pressure transmitter links the outlet supply header of the chillers with the system return header and helps transport chilled water, when the dif ferential pressure becomes low back toll the suction side of the chilled water pumps. The chilled water expansion tank directly connects with both the demineralized water system and the plant ventilation chilled water system. It either provides makeup water to or receives water from the chilled water system depending upon thermal expansion, contraction or leakages occurring within the system. A valve 9 arrangement is provided at the demineralized water connection (see figure 9.4-9) to control the flow from the demineralized water system into the tank. The tank is prcvided with a vent and a drain connected to-the floor drain system. Expansion tank water levels are monitored and indicated in the control room at all times. Annunciators indicate design low-water levels.

After a containment isolation signal, the containnent isolation valves in the supply and return lines, which supply water to the containment recirculation and neutron detector well cooling coils, are automatically closed, as . required. The plant ventilation chillers and the recirculation pumps are autonatically shutdown upon reciept of a containnent isolation 9 signal, and during loss of offsite power.

After a loss of offsite power the emergency standby diesel generators automatically power the Class 1E electrical buses.

The plant ventilation system is anota needed for "safea plant shutdown. However, the containment portion of this system will operate during a loss of offsite power or shutdown to avoid possible damage, of non-safety related equipue nt. This requires 9 the operation of 'wo chillers. The plant veulitation system is automatically tripped on reciept of an "S" signal.

GIBBSSAR 9.2.8.3 Safety Evaluation The system is non-nuclear safety related and Seismic Category I in the containnent to avoid damage to adjacent safety related 9 equipment.

The performance 7f all essential equipment is monitored from the control room. Low or high flows, pressures, and temperatures which would reflect system galfunction are visually and audibly annunciated in the control room. Leakage in the system can be identified by control room indicators. The operator takes apprcpriate action to curt a continued deterioration of system conditions.

All the major components of the system including piping and its appurtenances, are located inside Seismic Category I structures.

The pumps are arranged in parallel and connected to the chiller units (in parallel) and are located in the primary plant 9 ventilation equipment area of the auxiliary building. Redundancy in equipment is sufficient to handle all conditions, ncrmal or adverse, attendant with the design modes of operation.

Failure of a single component of the plant ventilation chilled water system does not have an adverse effect on the ability to safely shutdown the plant or to maintain the plant in a safe shutdown condition.

9.2.8.4 Tests and Inspection Requirements Shop inspection and testing are performed for all rotating equipment and modular controls. The systen is initially tested for proper flow paths, flow capacities, and mechanical operabilities and is adjusted accordingly.

Periodic chemical examination of the chilled water is made for pH and corrosion-inhibitor content, and adjustments are made, if required. Sufficient instrumentation is provided to monitor system performance. Periodic visual inspection is conducted, as required, without interrupting system operation.

The system is comprised of two independent trains. Each train O

consists of two 50-percent-capacity water pumps, one 100 percent-capacity chiller unit, associated piping, valves, and controls. The chiller units are not required at sites where cooling water, either service water of a high quality or CCE system water, is availahle at a temperature helow 700 Eachl9 train is connected to a separate Class IE electrical bus supplied by emergency standby diesel generators.

The return water line of each train is as shown in Figure 9.4-5 connected to a separate chilled water expansion tank. Each tank is connccted to the reactor water makeup water system, fire 9 protection system and the demineralized water system through a common header.

Fedundancy of equipnent and power supplies is incorporated into the system design to conpensate for a single failure of any compcnent. l9 The system is designed to Seismic Category I and ASME Code III tequirements, and classified as ANSI nuclear safety class 3. l9 9.2-22 Amendment 9 h

GIBBSSAR 9.2.9.2 System Description The ventilation safety feature chilled water system is shown schematically cn Figure 9.4-5 The system design includes two trains, each comprised of two 50 percent-capacity water pumps, one 100-percent-capacity centrifugal-type chiller unit, piping, valves, and controls. The trains are physically separated by the valve arrangements as shown in Figure 9. 4- 5. The pumps and chiller on a single train are sized to handle the total of postulated heat loads to which the train could be subjected. Consequently one train is normally operational while the other remains on standby.

During normal operation, cooled water is delivered by a manually started water purp-chiller unit arrangement via a piping network to the areas specified in subsection 9.2.9.1 (except areas specified in a, b, and c) . The PHR pump-room coils which are l interlocked with the PHR pumps are supplied during reactor startup, reactor shutdown and LOCA. The containment spray pump and safety injection pump room auxiliary cooling coils which are interlocked to the pumps are supplied following a LCCA or when the pumps are tested. The water flow rate of each pump train is 9 monitored cooling coil.

and is contingent on the chilled water supply to each Each of these water supplies is constant, except that through the uncontrolled access area and control roon cooling coils which are regulated by temperature modulated valves with provision for manual operation from the centrol room. The chilled water flow to each coil depends on the design tenperature for that area. The tenperature of the chilled water distributed to the areas served is monitored and indicated locally and in the control room. This temperature can te maintained constant by properly setting the chiller units when these are included in the system design. However, when service water or CCW system water, is used for coolir.7 this temperature may fluctuate. g Pedundant recirculation lines fitted with valves, flow meter, and differential pressure transmitter links the outlet supply header of the chillers with the system return header.

The chilled water expansion / surge tanks are linked with the demineralized water system, the fire protection system, and the reactor nakeup water system. The fire protection or reactor 9 makeup water systems are utilized when demineralized water is not available. Their function is to provide makeup water to the chilled water system. Makeup water is required as a result of leakages or thermal contraction within the system, whereas receipt of water by the expansion / surge tanks is a result of water thermal expansion within the system. The tanks vent to the floor drain system via a common header. The piping system provided with the tanks is fitted with valves and controls which are cperated locally or remote manually from the control room.

Surge tank water levels are monitored at all times and displayed locally and in the control room. Annunciators indicate high and low levels. A failure in one loop does not affect the 9 performance of the other.

a. Leakaoe and Control The chilled water expansion tanks accommodate surges resulting from t .' ' thernal expansion or contraction of water. To maintain the desired pressurization within the system the tank is located at an elevation above all components in the system. A drop telow a predetermined level in either surge tank level during operation llh indicates leakage within the system. The water levels in the tanks are in?.icated locally and in the control room.

9 The fire protection system provides a seisnic Cateorgy I source of makeup water needed by the ventilation safety feature chilled water system during accident conditions and when the demineralized water system is nonoperational or overburdened, or both. An outlet header discharges excess water from the tanks to the floor drain system.

GIBBSSAR The performance of all essential equipment is acnitored fron the control rocm. Low or high flows, high or 1 pressure or temperature conditions, all of which would a rfect the systen adversely, are annunciated in the centrol room. Leakage in the systen can be identified, locally and in the control room by the water level indicators. The operator nust take appropriate acticn tc avoid further deterioration of the system conditions.

All the najor components of the system, including piping and its appurtenances, are located inside seismic Category I structures.

These structures which enclose the pumps and chiller units are designed to preclude coincident damage to redundant equipnent in the event of a postulated pipe rupture, equipment failure, or missile generation. The pumps and chiller units are located at an elevation which is above the highest water level that night occur as a result of equipment failure within the auxiliary building. Fedundancy in trains is sufficient to handle normal or adverse conditions conconitant with the design modes of operation. Standby equipment is autonatically started as thel6 failed unit becones inoperable.

9.5.2 Communicat ion Systems 9.5.2.1 Design Panes Intraplant and plant-to-of f site communicat ion syntemn are provided among the plant buildinos, switchyard, and the public telephone system. Te le phone s , I.ublic addrenn nprakern, and handsets are conven ient ly located to permit ef fect ive communications between personne l durinq no rma l operation, maintenance periods, startup operatlon, shutdown, and refueling of the plant. A two-way portable radio system is also provided for use by the fire brigade and other operations rersonnel 9 required to achieve safe plant shutdown.

Sound-powered telephone systems , independent of all external power sources, are provided in critical areas as a backup to the public address systems. These diverse means of communication are physically independent to prevent loss of all systems as a result of a single failure. Diverse capabilities for plant-to-of f site emeroency conmunications with public safety agencies are 9 provided. An emergency alarm system is installed which 1 rovides a unique alarm signal to ensure personnel evacuation.

9.5.2.2 System Dcscription lll Detailed description and drawings will be provided in the Utility Applicant's SAP. The intraplant and plant-to-offsite communication systems consist of the following systems:

a. Public Address System The public address system provides separate channels f or paging and party lines to permit communication throuchout the entire plant including the main office and control room. The system also permits two-way communication between two or more locations vital to the operation of the olant and the safety of personnel.

The page-party line loudspeakers are powered by individ ua l i amplifiers and power to this system is supplied from a source which is available upon loss of of f site power. The voice-paging channel output is clearly audible above the highest expected 3 noise levels under both normal and accident conditions. Separate and independent party lines permit communications between handsets only, thereby making the page channel available to others.

Three party lines are supplied in addition to the page channel.

All three lines are available at each handset location (except inl 9 9.5-24 Amendment 9 llh

GIBBSSAR elevat <rs) . A page party line (with only one party line) handset station is installed in each elevator to permit communication in an emergency situation. Selection of a desired channel is 9 achieved by means of a multiposition switch provided as part of each handset station. Both the page channel and the party line channels, which are independent, may be used siguitaneously without interference.

9.5-24a Amendment 9

GIBDsSAF O

b. Intraplant Telephone System An independent private automatic branch exchange ( P APX) dial telephone system is used for uninterrupted privat e conunun i ca t ionn between plant areas that are routinely occupied. It a l no nerve n areas vital to plant operation, which may l'c occupied on a nonroutine basis during certain modes of plant operatlon, such as fuel building, control rod drive equipment area, hot nhutdown panel area, switchyard, and the intake structure of the service water system.

The PABX telephone system is int egrated with the public address nage-party system through an isolat ing device to ensure that a sinale failure in either one of these two systems does not affect safe and reliable operat ion of the other system. Power is supplied to the PABX telephone system from a source which is available upon loss of offsite power. Also, if the PABX telephone system's normal ac power supply is lost, a telephone station in the control room, the hot shutdown panel A and D rooms and in the security central alarm station remains operable by deriving its power f rom the public telephone system.

9 The PABX telephone system is connected to the public telephone system by trunk lines. $

c. Intraplant Sound-Powered Telephone System A sound-powered telephone system, independent of all other systems and external power sources, is provided in critical areas to serve two purposes: to provide communicat ions and servr as a backup to the public address page-party system, and to provide unint err upt ible communication channels for maintenance, calibration, testing, and refueling activities. All sound pcwered telephone cables are routed in conduit s reserv'd only f or that function.

This system consi sts of three subsystems as follows:

Subsystem On3: Maintenance Loops - Consists of a two channel hard-wired communication link between the control area and critical plant areas.

Subsystem Two: Pefueling Loops - Consists of a two-channel hard-wired communication linP between the the Control Poom area, fuel handling area, and reactor operating floor. This subsystem is primarily provided for refueling 9.5-25 Amendment 9

GIBBSSAR operation. One channel of the refueling loop will be used primarily for refueling opera-tions while the second channel will be used for maintenance, ca11raation, and testing pur-poses. Subsystems one and two share the same conduit system.

Subsystem Three: Emergency Loops - Consists of a two-channel hard-wired communication link between the hot shutd)wn panels and safety-related equipment areas. This system is primarily provided for commt.nications in the unlikely event that the Control Poom becomes inaccessible.

Each emergency loop channel is routed in its own conduit system. No other systems, sound powered or otherwise, share these conduits.

The headset jack stations are conveniently located on panels in the Control Poom and in critical areas.

Communication can be established between the Control Foom and any 9 local panel or between two local panels by suitably plugging the headsets into jack stations which are mounted either in the panel or nearby. This system provides standby communication capability and does not depend on external sources of power other than the human voice.

The number and location of sound-powered telephone system receptacles are adequate to bring the plant to a hot shutdown or a cold shutdown panel and other areas. from the Control Poom or from the hot shutdown The sound-powered telephone system can be used as a backup to the public address page-party system in the critical equipment areas of the plant. One independent howle r loop per unit is provided for sound-powered signaling purposes.

d. Intraplant Portable Radio Transmitter-Peceiver System Two separate communication channe[s of unique wavelengths for the operating personnel, maintenance personnel, and fire fighting squad are provided to enable two-way radio voice communication between the Control Foom and va rious plant buildings. The Control Room is equipped with the hand-held transmitter-receivers. Portable transmitter-receivers operating on either one or both channels are provided for use by operations, maintenance, and fire fighting pe rsonnel for communication between various areas of the plant, required to 9.5-25a Amendment 9

GIBBSSAR O

aciieve safe plant shutdown. This system does nor interfere with tie communications capability of the plant security force.

"o improve reception from various plant buildings, fixed

epeaters, coaxial slotted cables, or both, are installed as required in these buildings. The fixed repeaters are protected from exposure fire damage, to the greatest extent practicable.

The use of switchyard remote supervisory carrier current equipment is discussed in the Utility-Applicant's SAP. The portetle radio carrier frequencies will not interfere with such equipment.

The portable radio communication is designed so as not to affect the actuation of protective relays.

e. Offsite Communication Systems Two diverse method s of plant-to-offsite commtinication are provided:

1) Public telephone system 9

2) Two-Kay Padio System O

The intraplant telephone system is directly connected to the public telephone system; each plant telephone is available for of fsite communication.

A two-way radio transmitter-receiver system is also provided for emergency communication between plant and offsite public safety agencies. It can be operated from the control room, remote hot shutdown panel 3 and panel B rooms and from the quardhouse.

This two-way radio is described in the security plan.

Tre two-way radio system and telephone system are independent, and provide reliable plant-to-of fsite communication. A failure of one system does not result in complete loss of offsite communications.

f. Emergency Evacuation Alarm System The evacuation alarm is generated by a solid state multifrequency audio ascillator capable of producing five distinctive tones which can be heard over all plant paging zones via the public 9.5-25b Amendment 9 k

GIBBSSAR address page party system. One of the distinctive tones, which sa ti sfies the NRC Pegulatory Guide 8.5 requirements, is designated for the evacuation alarm signal.

The evacuation alarm system, including the multifrequency audio oscillator, is powered by a source available upon loss of offsite power and provides a unique alarm signal to ensure personnel evacuation in case of an emergency. The alarm is initiated by the Control Room operator in the event of a plantsite evacuation emergency.

9.5.2.3 Evaluation The following evaluation is intended to establish the adequacy and redundacy of the plant communication system design:

a. Intraplant Systems Each intraplant system, i.e., the public address page-party system, PABX telephone system, sound-powered telephone system, and portable radio transmitter-receiver system, is designed to 9

provide the required intraplant communications during and after accident conditions as well as for plant operation fire fighting and maintenance purposes. Failure of any one of the above syst ems does not result in a failure of any other system. The power supply for the PAEX telephone system is provided from the on-ESF bus. Upon loss of total ac power to the PAEX telephone system, a telephone in the control room, the hot shutdown panel A and B rooms and in the security central alarm station remains operable by deriving power from the public telephone system.

Power supply for the public address page-party system is provided from a source available upon loss of offsite power. The PABX telephone and public address systems are connected through an amp 1 'fier device which acts as an isolating device. This ensures that any single failure in any one of these two systems does not result in a failure of the other system. The public address page-party system handsets and speakers are conveniently located to cover all critical areas. Each area of the plant is served by a separate public address page party system cirucit to confine the system outage to the area the faulty circuit serves.

The sound-powered telephone system is independent of all external power sources and its headset jack stations are conveniently leca ted throughout the plant. This system can be employed as a tackup to the public address page-party system in critical equipment areas of the plant. In addition, redundant components 9.5-25c Amendment 9

GIBBSSAR O

and cabling in the sound-powered telephone system are separated to prevent failure of both systems beause of a single f ailure.

The intraplant portable radio transmitter-receiver system is powered by rechargeable batteries and has two redundant channels.

This system can be employed as a hackup to the public address paae-party and sound powered systems in case of emergency, or if a communication line or trunk is severed, as a result of an accident.

b. Plant-to-Offsite Systems There are two independent plant-to-offsite communication systems available for the use of Control Room ope rators. The availability of these systems during and after the accident 9 condition is enhanced by the fact that cach enters the plant via different means.

The public telephone lines (trunk lines) are connected to the plant PABX telephone system. This extends the use of public telephor e lines throughout the plant.

The plan -to-offsite two-way radio communication system can ce used as a backup to the public telephone system. This provides &

W communication between the plant operator and public safety agencies. The power to this system is provided from a source available upon loss of offsite power. Also, there is an inherent redundancy in this system since it has two separate communication channels.

9.5-25d Amendment 9 lll

GIBBSSAR 9

9. 5. 2. 4 Inspection and Test Pequirements At the completion of installation, all communication systems are inspected, tested, and adjusted (if required) to ensure proper l 1 coverage and audibility under the maximum plant noise levels during the various operating conditions, including the accident 9 condition.

Since the communication systems (except the sound-powered telephone and offsite two-way radio systems) are used on a daily basis, periodic testing is not required. Periodic testing of the sound-powered telephone and offsite two-way radio systems are ccheduled to ensure their operability. 9 Preoperat ional and periodic testing demonstrate that the frequencies used for portable radio communication do not affect the actuation of protective relays.

System design is equal to, or exceeds, the requirements of IFS Lighting Handbook (5th edition) . Illumination sources containing mercury, such as floutescent, me rcury vapor, met al halide or high pressure sodium lamps are not used in areas where they are restricted such as in the containment, waste procensino area, and portions of the fuel handling area, sa tequa rd s area, auxiliary area and turbine building; incandescent or quartz iodine type fixtures are provided in these areas. When necessary, means are provided in floor drains to preclude mercury 9 cont amination of the radioactive waste processino system. If mercury or iodine in a lamp becomes activated, it is disposed through the radioactive waste processing system.

9.5.3.2 Emergency Lighting System AC and de emergency, reduced level, lighting is provided in locations where saf ety-related f unctions are performed or where personnel safety is involved. These areas include:

a. Control room

b. Diesel generator rooms

c. Battery rooms

d. Hot shutdown panel location l9

e. Safety-relat ed equipment locations

f. Hazardous areas

g. Primary access routes to and from the oreceding areas, fire areas and primary exits The ac-emergency lighting system consists of certain lighting fixtures that are part of and are powered from the normal power system; in the event of loss of offsite power, only these ac-emeroency lighting fixtures are automatically connected to the 9 non- saf tey-related diesel genera tor. Power is available to these lights as soon as the diesel generator has achieved rated voltage and frequency and has been connected to the distribution system.

As a backup to the ac-emergency lighting system an independent de-emergency, low level lighting system is provided in critical plant areas. The de system, conslsting of central battery fed lights and individual battery pack units, is automatically and immediately energized upon loss of ac power and automatically 9.5-27 Amendment 9 jgg

The most crucia l areas, such as the control room, major remote shutdown areas and vital access routes between them have lights energized from the non-Class IF station battery. In addition, these areas, as well as all areas that must be manned for safe shutdown and the access and egress routes between them and between all fire areas incorporate fixed, self-contained lighting consisting of sealed-beam or, where not restricted fluorescent units, with individual eight-hour minimum battery power supplies. Safe shutdown areas include those required to be manned if the control room must be evacuated. When remote sealed beam heads are used they are located in the same fire area as the battery pack that energizes them. Each battery pack unit contains an individual battery and an integral automatic charger.

Exit lights are energized from the ac-emergency lighting system 9 with de-emergency lighting provided nearby. Phosphorescent, non-electric exit and directional signs are used where required.

Suitable sealed-beam, battery-powered portable hand lights are provided for emergency use by the fire brigade and other personnel required to achieve safe plant shutdown. These units and spare batteries are located at strategic locations throughout the plant. Security lighting is discussed in the plant sec urity plan.

9.5.3.3 Failure Analysis Since the de and ac lighting systems are independent, a failure in one system does not cuase the other system to cease functioning. A restraining cable is used on each lighting fixture near safety related equipment inside critical plant areas which could become falling objects.

9.5.3.4 Inspection and Testing 9

The ac and oc emergency lighting systems and battery packs are inspected and tested periodically to assure availability at all time s. A regular program of periodic battery replacement is followed to assure reliable operation or the fixed battery packs and portable hand lights. Sealed beam lamps are periodically cleaned to assure maximum output and sufficient replacements are stocked at all times in the plant.

GIBBSSAR The auxiliary feedwater system also supplies auxiliary feedwater to the steam generators during other modes of plant operation such as the following:

a. The auxiliary feedwater system maintains the proper water level in the steam generators during cold startup operation. The pumps supply feedwater until sufficient steam can be generated to operate the main feedwater pump turbines.

b. When the reactor is maintained in the hot shutdown condition for an extended period of time, the small amount of feedwater flow necessary to maintain the steam generators water inventory may be switched from the main feedwater pumps to the auxiliary feedwater system.

10.4.9.2 System Description

a. General The auxiliary feedwater system flow diagram is shown in Figure 10.4-3. The system includes an adequate storage of feed quality water, and adequate pumping capacity to supply the steam generators, and system piping.

The system supplies water to the steam generators where it is converted into steam by the heat transferred from the primary coolant which removes decay heat from the reactor core. A portion of the generated steam is used in powering the auxiliary feedwater pump t urbine. The remaining steam is dumped to the condenser or released to the atmosphere through the power-operated relief valves or the main steam safety valves.

A safety class auxiliary feedwater storage tank provides storage of deaerated feed quality water for immediate use. This amount 6 of water is sufficient to maintain the plant for 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months at hotl 9 standby, then cool the primary system at an average rate of 50 Fl 6 per hour down to 350 F hot leg temperature and 400 psig in 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months at which time the RHR system is capable of operation. 9 A floating diaphragm arrangement in the tank prevents air leakage into the liquid. The stainless steel tank is not corroded by deaerated demineralized water.

One supply line from the auxiliary feedwater tank supplies two electric-motor-driven pumps and turbine-driven pump. Backup source is station service water under all conditions described in 6 Table 9.4-4. The alternate backup is the condensate storage 10.4-28 Amendment 9

Equipment is also provided for conpacting and packaging low-radiation-level miscellaneous solid compressible wastes that result from riant operations and maintenance. The radicactive waste packages from this system conform by design to the requirement: af 10 /TR Parts 20, 50, and 71 and of United States DepartRent of Transportation (DCT) 49 CFR Parte 170-178.

Compliance with NRC, DCT, and state regulations is determined according to radioactivity measurenent and the amount of waste processed. If radioactive levels are too high, corrective action is taken either by permitting radioactive decay diluticn or by shielding. 9 The design objectives of the solid-waste ganagement syster include the following:

a. To provide a means of solidifying radioactive liquids and encapsulating or compacting radioactive solid wastes 2 generated by reactor plant operations

t. To provide adequate equipment and storage area shielding for the protection of operating personnel pending shipment of waste to disposal facilities

The equipment is arranged so that the resin sluice water, after entering a demineralizer vessel, is returned to the spent resin storage tank for reuse. The system is 2 designed to transport spent resin to the spent resin storage tank withcut generating large volumes of liquid waste. This is accomplished by reusing the sluice water for subsequent resin sluicing operations.

c. Expended Filter Cartridge Handling Expended filter cartridges are removed for disposal by means of a filter transfer cask. The transfer cask is shielded to reduce operating personnel exposure.

b. Spent Resin Handling This part of the waste trocessing system sluices resin from the demineralizers and transports resin from the spent resin storage tank to the waste solidification plant.

1) Resin Sluicing Before resin sluicing begins, the demineralizer is valved out of service and the flow path aligned from the resin sluice pump through the process line of the demineralizer, through the screen at the top of the demineralizer, and back to the spent resin storage tank. 2 The resin sluice pump provides flush water for loosening the bed for sluicing. After approximately 10 minutes of back-flushing, the pump is shut of f and the valve in the back-flush circuit is closed. The sluice line is opened, and the resin sluice pump is restarted. The resin then flows to the spent resin storage tank. After the resin sluice pump is shut off, fresh resin is added via the resin fill line and the valve is closed.

The flow path is now aligned in the same manner as for resin flushing, e.g., through the process line, through the screen at the top of the demineralizer, and back to the spent resin storage talk. The pump is then started to remove resin fines, thould any remain. The valves are then realigned for norma? process operation. At no time are the resins sluiced through the spent resin sluice pump.

2) Pesin Transfer To Solidification System Ehen sufficient spent resin has been accumulated in the spent resin storage tank, the valves in the line to the waste solidification package are opened and all other 1 9 valves are closed. The tank is then pressurized with nitrogen. The solidification package valves are then 2 opened and the resin is transferred. During transfer e nitrogen is forced through the spargers in the tank 9 11.4-10 Aaendment 9

GIBBSSAR botten to level the resin and maintain the tank pressure. Ehen transfer to the waste solidification package is completed, the 9

transfer valves are closed and the tank pressure is relieved to the plant vent. The transfer valves are then flushed.

c. Expended Filter Cartridge Assembly Processing Operation The filter transfer cask is used to renove and dispose of radioactive spent filter cartridge assemblies in the following manner:

1) To change the filter, it is first valved out of service, vented and drained.

2) The filter transfer cask is positioned alongside the filter conpartnent concrete shield plug. The shield plug is lifted and placed down beyond the work perimeter. 2

3) The filter housing bolts are disengaged, and the filter housing head is moved to allow removal of the expended filter cartridge assembly.

4) The filter transfer cask is moved until the centerline of the cask is aligned with the centerline of the expended filter cartridge assenbly.

5) The filter transfer cask shielded base is renoved and the hoist lowered to engage the cartridge assembly.

6) The grappled cartridge assenbly is then raised into the shield cavity, and the shield base secured to contain any liquid or particulate that may drip curing transit. l 11.4-10a Amendment 9

GIBBSSAR

7) A monorail is used to move the filter transfer cask to the hatchway, through which the cask is lowered to the filter loading area.

8) The filter transfer cask is lowered until it is positioned above a disposable container. l9

9) Khen centered above the container opening, the contained expended filter cartridge assembly is lowered into the disposable container. The filter transfer cask is then decontaminated by allowing the decontamination water to enter the container.

10) The container is then moved to the fill area for-solidification l9

d. Compactor Operation l2 The compactor is used to compress low-radiation-level solid waste such as paper, disposable clothing, rags, towels, floor coverings, shoecovers, plastics, and respirator filters into drums. Compressible solid wastes are placed into the drums manually. The drum is placed on the drum support plate located at the front of the compactor and is centered by adjustable drum-locating pins. Before starting the operation, a shroud door with door lock must encloae the drun and the compressing cylinder rod and plate.

The assembly incorporates a fail-safe switch that does not permit the compaction operation when the compactor door is open. An operator initiates the compaction process by positioning an up/down switch in the down position, which energizes the hydraulic pump motor. The hydraulic pressure forces the ram down into the drum, thereby compressing the wastes. The shroud door is opened, the drum is removed, and additional wastes are added to the drum. The cycle is repeated until the drum is full. The lid is then installed, the clamping ring tightened, and the drum is stored pending shipnent.

Partially contaminated air during conpactor operation is evacuated by an integral blower, which directs airflow through a HEPA filter with air efficiency of greater than 99 percent. The filter outlet is connected to the auxiliary cuilding ventilation exhaust system.

j. Give an alarm on high radiation level by using a high-high set point alarm

k. Control the release of radioactive liquids, gases, and particulates produced in the operation of the plant by initiating prompt corrective action through automatic isolation systems, or via operator response Continuous monitoring means that the monitor operates essentially uninterrupted for extended periods. However, this does not mean that the monitors are maintenance free. Preventive maintenance is normally coordinated with plant shutdowns, and necessary maintenance or repair and calibration outages are minimized by equipment design. Consideration is gi ven to providing needed augmentation if conditions warrant.

The accomplishment of these general objectives by the continuously operating PERMS assists in maintaining for individuals in restricted and unrestricted areas, during both normal and accident conditions, exposure levels as low as reasonably achievable ( AL ARA) 11.5.2 System Description The RMS will be a current state-of-the-art system that has the PERMS and ARMS system integrated. The system will be dual dedicated microcomputers in communication with each other and a 9 distributed dedicated microprecessor for each system monitor.

11.5.2.1 Design Criteria The following criteria are used in the design of the RMS: l9

a. The system is of a digital rather than analog type. The digital system uses, adjacent to each detector element, microprocessors which preprocess the data and provide the capability of independent local readout when required. The hign-voltage supply is also located at this point. Such a system

~

allows computer handling of the data, and incorporates the most recent in solid-state processing equipment.

b. The digital system is subdivided into two groupings:

1) Monitors that serve as Reactor Coolant Pressure Boundary (RCPB) leak rate indicators; this group l 2 must be seismically qualified

2) Those not seismically qualified.

11.5-3 Amendment 9

GIBBSSAF The s eis tnically qualified channels are isolated f rom each other electrically with independent wiring to the central independent 9 pnysically separated consoles, so that each detector is unaffected by the operation of any other unit. Optical isolation at each detector provides channel independence.

c. All monitors register full scale if exposed to radiation levels up to 100 times full-scale indication without foldover.

d. The PERMS readout and controls are located in the control room so that they will be convenient to the operator, enabling proper overview of plant conditions. Additional local indication and alarms, where necessary, are provided to alert operating personnel, e.g., waste processing system control panel.

e. Each monitor automatically provides the control room with a rea dout, a high alarm, a high-high clarm, and a failure / loss-of-background alarm as a minimum.

Each monitor's high alarm is set at a level determined by operating personnel to allow attention to be drawn to positive increases in activity.

The high-high release rates arealarm is plant within chosen to ensure that the instantaneous l 2 technical specifications. Tnese values are dependent upon the maximum anticipated flow rates.

The failure / loss-of-background alarm actuates if the monitor loses its power source, or if there isn't a normal background level as a result of signal circuit failure or other similar failures.

f. Alarm setpoints are under the administrative control of the plant manager, or his authorized delegate. l

g. The proper operation of each detector is checked as required with a check source that is built into each detector but controlled from the control room. These check sources show a reading of approximately 30 percent of full scale.

h. Backup monitors are provided by placing monitors in series in appropriate discharge paths, as described in this section and located as indicated by Table 11.5-1.

i. Diversity of monitor types and principles are used to the extent feasible to enhance system reliability.

j. The monitors are placed where they are readily accessible and where the background is determined to be the lowest for the area.

k. Adequate lead shielding is provided so that background radiation has reasonably minimal effect on detector capability to sense low activity levels. The minimum detectible concentration is deemed to be that count rate associated with the background

GIBBSSAR h count rate plus two-times the background standard deviation.

Background is considered to be the larger of either 1 MR/bour of 1 meV gamma radiation, or the design maximum for the area, as given in Section 12.3.

1. Spare equipment is provided for those components requiring naintenance and natural replacement.

m. Equipment is placed indoors for protection from the effects of extreme winds, floods, tornadoes, or missiles, as aascribed in Chapter 3.

n. Environmental design conditions for the components, excluding detectors, are as follows:

II Ambient temperature range of -10 C to 50 C

2) Relative humidity of 30 percent to 100 percent (100 percent without visible water droplets)

3) Normal atmospheric pressure 15 psig g

q. Each analog channel has a minimum range of 5 decades. l9 11.5.2.2 Locations to be Monitored All normai and potential paths for release of radioactive material during normal reactor operation, including anticipated operational occurrences and accidents are being monitored as indicated by NRC Regulatory Guide 1.21. Based on this, monitors are provided for:

a. Process lines which may discharge radioactive fluids to the environs, in order to indicate and alarm when preestablished limits are reached or exceeded

b. Process lines which do not discharge directly to the environs, in order to indicate possible process system malfunctions, deteriorating performance, or failure by detecting increases in radioactivity levels e

11.5-5 Amendment 9

GIBBSSAR Section 11.5.2.5 lists the local locations of detectors: l2 Table 11.5-1 summarizes the detector information.

11.5.2.3 Anticipated Concentrations, Sensitivities, and Ranges The monitors use scintillation crystals (predominantly) or Geiger-Muller (G-M) tubes to detect either beta or gamma 11.5-Sa Amendment 9

GIBBSSAR radiatio n, or both over an energy range of at least 0.08 to 2.5 meV.

ANSI-N13.1, 1969 provides guidance on detector locations, sample line routes, and sampling of air streams.

The sensitivity and range of each detector, along with other pertinent factors such as preferred detector type, reference nuclide, and anticipated medium concentration are given in Table 11.5-1.

11. 5. 2. 4 Des cription of Liquid Process and Effluent Monitors, General Each channel of the system contains a completely integrated modular assembly.

When appropriate, in-line monitors are used. This provides complete monitoring of the Liquid as there is no possibility of improper sampling. consequently, pumps, which require maintenance, are not required, and auxiliary flow devices are unnecessary.

off-line monitors, when required because of temperature or other considerations allow for ease of chamber decontamination. If pressure differential cannot be used to assure proper off-line g flow, a quality pump is provided. A flow device is provided in W either case.

On-line (saddle or snowplow) type detectors may also be implemented. These have the same advantages as in-line monitors and, unlike off-line monitors since the existing piping is not altered, provide no additional flow blockages or sediment collection points. Their use is regulated by necessary sensitivity considerations.

Each in-line and off-line chamber as well as auxiliary piping is made of stainless steel of the necessary quality to conform to ASTM standards. In addition, all monitors, regardless of type, are capable of being decontaminated by rinsing in place.

11.5.2.5 Description of Liquid Process and Effluent Monitors, Specific The following paragraphs contain a brief description cf each of the liquid process and effluent monitors.

a. Auxiliary Steam condensate Monitor 11.5-6

GIBBSSAR 12.3.3.2 System Design Criteria Ihe atmosphere cleanup units remove contaminants from the exhaust air of the primary plant ventilation system (which includes the controlled-access exhaust, containment-purge exhaust, and f uel-handling building exhaust ventilation systems) , and from the hydrogen purge exhaust system.

These systens are described in Sections 9.4, 6.2, and 6.5. In addition to the use of the atmosphere cleanup units described previously, the emergency filtration units and emergency pressurization units of the control room HVAC system remove contaminants from the control room environment and prevent contaminants from entering the control room atmosphere during emergency modes of operation. The control room HVAC system is discussed in Sections 9.4.1 and 6.4.2 12.3.3.3 Component Design Criteria The components comprising the non-ESF atmosphare cleanup units are prefilter, HEPA filters (two) , iodine adsorbers, fans, isolation valves, and related instrumentation. Atmosphere cleanup units are comprised of the above components, with the addition of demister and heaters to maintain the relative humidity below 70 percent.

12.3.3.4 Testing, Isolation, and Decontamination Eacn atmosphere cleanup unit housing has permanent test connections for DOP (dioctyl phthalate) leak testing of the HEPA filters and refrigerant leak testing of the adsorber section.

Leak testing is performed semiannually on all units.

addition, a deluge system is provided to extinguish an adsorber In section fire if a charcoal adsorber is used. The operation of the deluge system is discussed in Section 9.5. Inspection and testing requirements for ESF and non-ESF filter housings are disc ussed in subsection 9. 4.1. 4. .The arrangement of these units allows access to the unit and equipment by personnel for maintenance and testing. All housings have multiple drains which are connected to the equipment and floor drainage system.

Decontamination water stations are in proximity to each unit to facilitate decontamination. Figures 6.5-1 and 9.4-17 illustrate typical layouts for ESP and non-ESF atmospheric cleanup units, respectively.

12.3-17

GIBBSSAR h 12.3.3.5 Maintenance All housings are designed to provide ample room fot maintenance of equipment and filters and to minimize the radiation exposure l 1 to personnel during filter replacement. The criteria for replacement of filters are established on the basis of maximum allowable resistance of the dirty filter or minimum radiation exposure to personnel, or both. Each Silter train is provided with a pressure indicator. High pressure actuates an alarm in tne control room. Each filter of the filter train is provided with a local pressure indicator. Upon reaching the maximum resistance, the filters are replaced. The maximum allowable resistance f or each type of filter is indicated in Table 9.4-4.

The criteria for replacement of the adsorber section is based on the deterioration of adsorber ability to remove radioactive iodine from the exhaust air. This efficiency is determined by laooratory testing of representative samples of the activated charcoal exposed simultaneously to the same service conditions as the adsorber section. Each sample has the same qualification and batch test characteristics as the system adsorber. Samples are tested periodically (approximately semiannually) in accordance g with Regulatory Position C6.b of Regulatory Guide 1.52. The W adsorber section is replaced after the last sample has been removed and tested, or if one of the samples fails to meet the requirements of NRC Regulatory Guide 1.52, Table 2.

12.3.3.6 Conformance to Regulatory Guide 1.52 The ESF and non-ESF atmosphere cleanup units conform to the regulatory positions and recommendations of Regulatory Guide 1.52 as shown in Table 6.5-1.

12.3.4 Ar e a Radiation and Airborne Radicactivity Monitoring Instrumentation The ABM system is part of a,n integrated system of the RMS 9

including the airborne radioactivity monitoring instrtmentation of the PERMS. This RM system is described in Section 11.5 i 12.3.4.1 Area Radiation Monitoring System Fixed, gamma-sensitive monitors are located throughout the plant for the protection of personnel.

Cuestion 111.55 (3.6.2.1)

Section 3.6.2.1.2 (page 3.6-6) of the SSAR adopts Branch Technical Position MEB 3-1 as the basis for determining post ulated pipe break locations in high energy piping systems outside containment. An element of this BTP (position B. I.b) is the establishment of criteria for piping in the containment penetration area where pipe breaks need not be postulated.

Unfortunately, all the criteria are not ccatained in the BIP.

Therefore, commitment to the BTP is not sufficient, in and of itself, if pipe breaks are not to be postulated in the containment penetration area. 9 Therefo re, it will be necessary to expand section 3.6.2.1.2 of the SSAR to indicate that either:

(1) Pipe breaks will be postulated in the contairaent penetration area using the criteria of positions B.1.c and B.1.d; or (2) In addition to neeting the criteria of position B.1.b, all piping in the containment penetration area will have a 100 percent volumetric examination of all circumferential and longitudinal welds during each inspection interval (IWA-2400 of Section XI of the ASME Code.)

GIBBSSAR guesMon_B 2 3 10 Confirm that all stainless steel components subject to the provision of Regulatory Guide 1.44, Position C.3, will be in the solution annealed and water quenched condition.

Eespgnse 122 2 10 GCH's position concerning stainless steel components subject to the provision of Pegulatory Guide 1.44, Position C.3, requires that annealed and quenched materials be used and that the 9 material is not unduly sensitized during manufacture and installation, and that the material is protected against contaminants which would aid in causing cracks. Position C.3 of the Pegulatory Guide 1.44 requires testing to verify the nonsensitization of austenitic stainless steel forms other than

" plate sheets, bass, pipes and tubes". GSH also excludes from sensitization testing, those forgings, fittinas and other shaped prod ucts , which do not have inaccessible cavities or chambers which would preclude rapid cooling when water quenched, as denoted in GIBBSSAF S6ction 5.2.3.4. '
