CALLAWAY - SP CHAPTER 11.0 RADIOACTIVE WASTE MANAGEMENT 11.1 SOURCE TERMS This section presents the design bases for determining the source terms for radioactive releases from the plant, for shielding within the plant, and for accident analysis performed in Chapter 15.0. The source terms used for releases, shielding, and accident analyses are based on 0.12, 0.25, and 1.0 percent fuel defects, respectively.

11.1.1 RADIOACTIVE CONCENTRATIONS AND RELEASES Reactor coolant and secondary coolant specific activities for an assumed 0.12-percent fuel defects and an assumed 100 pounds per day primary-to-secondary leakage are listed in Table 11.1-1. These activities are used for calculational purposes only and may not represent actual reactor coolant and secondary coolant specific activities. Actual concentrations vary depending on plant conditions at any particular time. The basis for calculating these sources is Regulatory Guide 1.112. Compliance with Regulatory Guide 1.112 is discussed in Table 11.1-3. Appendix 11.1A provides a comparison of the input used for the GALE Code with the generic input identified in the GALE Code.

The decontamination factors applied are based on Regulatory Guide 1.112. A description of liquid leakage rates, process paths, and associated component activity levels is contained in Section 11.2 and Appendix 11.1A. A description of gaseous leakage rates, process paths, and associated activity levels is contained in Appendix 11.1A and Sections 11.3 and 9.4. In-plant airborne activity concentrations and other data regarding the ventilation systems are provided in Sections 12.3 and 12.4.

Prior to the licensing and operation of a nuclear power plant, the applicant includes an estimate of the radioactive effluents and the resulting public doses in FSAR Chapter 11 per the requirements contained in 10 CFR 50.34(b)(3). This is provided to ensure the proposed radwaste treatment systems will be sufficient to ensure compliance with radioactive release criteria specified in 10 CFR 20 and 10 CFR 50 Appendix I (or RM 50-2 for Callaway). The assessments presented in Chapter 11.1 are based on nominal assumptions and generic models that were appropriate at the time the original FSAR was written. They represent assumptions chosen for the purpose of estimating public dose consequences. They do not represent design or operational requirements. Actual operational data or system usage is expected to vary from the chosen assumptions, and may be more or less conservative than the assumptions presented in Chapter 11.1.

During operation, compliance with effluent release limits is ensured and controlled by compliance with FSAR Chapter 16 and the Offsite Dose Calculation Manual (ODCM).

Chapter 16 and the ODCM provide detailed controls on effluent limits (both concentration and dose limits), monitoring requirements and performance of dose calculations. They also require operation of radwaste treatment equipment, if the projected dose exceeds a 11.1-1 HISTORICAL

CALLAWAY - SP small fraction of effluent ALARA guidelines. If effluent ALARA release guidelines are exceeded, or if treatment equipment is not operated when necessary, special reports to the NRC are required. These reports must provide the corrective actions being taken to ensure the guidelines are not exceeded in the future. Chapter 16 and the ODCM require the use of actual measured concentrations of radioactivity released to verify compliance with effluent limits. Compliance with effluent limits is verified frequently during the year.

Assuming operation within the Chapter 16 limits on primary coolant activity, it would take a long enough time to approach the limits such that the routine verifications will provide sufficient advanced indication to allow for corrective actions. Such corrective actions would ensure all annual dose limits are met.

Therefore, compliance with effluent limits and regulations is controlled by Chapter 16 and the ODCM, not by meeting parameters or assumptions provided in Chapter 11.1. The assessments provided in Chapter 11.1 are a historical perspective of the basis behind the original radwaste system design. It was not the intent to operate within the bounds of each detailed assumption. As such, the parameters in Chapter 11.1 related to estimates of public dose from effluents are not updated, nor would it be useful to compare such parameters to actual plant operation. A more accurate and useful assessment of effluent levels and the public dose from effluents can be determined by referencing the Annual Radiological Effluent Report, Annual Radiological Environmental Monitoring Report and the routine estimates of dose required by the ODCM.

When there are proposed changes to plant design, the LIR required per APA-ZZ-00140 for the modification process requires an evaluation of the potential effects on normal radiological effluents. If the initial screening determines that there may be some effect, a more detailed Final Environmental Evaluation may look at the parameters in Chapter 11.1 for a historical basis, but the review primarily considers the effects of the change on the actual measured effluents and the ability to meet the requirements of Chapter 16 and the ODCM. Informaton describing the Radioactive Waste Handling Systems required by 10 CFR 50.34(b)(2)(i) is addressed in FSAR Sections 11.2 and 11.3. These FSAR sections are not designated "historical" and will be updated as system modifications are made.

Regulatory Guide 1.70, Revision 3, "Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants," Section 11.1 requires that certain information on the sources and releases of radioactivity that serve as design bases for the various radioactive waste treatment systems be included in the PSAR including, mathematical models and parameters used to calculate source terms. Regulatory Guide 1.70 further requires that the FSAR should provide additional information required to update the PSAR to the final design conditions. Further, AmerenUE is committed to Regulatory Guide 1.181 which endorses NEI 98-03, Revision 1 "Guidelines for Updating Final Safety Analysis Reports." Section A3 of NEI 98-03 states that "Historical information provided in the original FSAR may have become out-of-date and is not expected to be used to support current or future plant operations or regulatory activities. Accordingly, it may be appropriate to reformat such information to distinguish it from UFSAR information actively maintained by licensees to describe the updated plant design and operation."

11.1-2 HISTORICAL

CALLAWAY - SP While information regarding originally estimated source terms in FSAR Section 11.1 will remain in the FSAR, it will be designed as historical in accordance with NEI 98-03.

Regulatory Guide 1.70 does not provide for the designation of FSAR information as historical. Therefore, an exception to Regulatory Guide 1.70 is taken in this regard and is noted in Table 3A-1.

11.1.2 SHIELDING Reactor coolant and secondary coolant source terms used for shielding are based on 0.25-percent fuel defects. The source terms and the parameters used to calculate the source terms are given in Table 11.1-4 and Appendix 11.1A, respectively. Table 11.1-6 provides the isotopic composition of the contained sources for radioactive waste management systems and for large, potentially radioactive outside storage tanks.

11.1.3 ACCIDENT ANALYSIS SOURCE TERMS Source terms used in accident analysis are based on assumptions presented in Section 15.0.9 and in the sections discussing individual analyses.

CALLAWAY - SP APPENDIX 11.1A - PARAMETERS FOR CALCULATION OF SOURCE TERMS FOR EXPECTED RADIOACTIVE CONCENTRATIONS AND RELEASES 11.1A.1 Regulatory Guide 1.112 provides guidelines for developing radioactive source terms. The following parameters and models are used to calculate radioactive source terms for the evaluation of radioactive waste treatment systems in determining the impact of radioactive effluents on the environment. Except where indicated and justified, the source terms are calculated using the PWR-GALE Code. Figure 11.1A-1 shows a block diagram of liquid releases, and Table 11.1A-2 and Figure 11.1A-2 provide the volume, radioactivity level, and decontamination factors (DF) for each liquid path. The values shown are for the standard power block design with an anion bed recycle evaporator condensate demineralizer. A mixed bed demineralizer is optional. See Chapter 11.0 of the Site Addendum for the type used and any associated variations in the radioactive release values.

Figure 11.1A-3 shows a block diagram of gaseous releases, and Tables 11.1A-3 and 11.1A-4 provide the volume, radioactivity level, and DF for each gaseous path.

11.1A.2 The basic plant data for the source term calculations are provided in Table 11.1A-1.

CALLAWAY - SP 11.2 LIQUID WASTE MANAGEMENT SYSTEMS Several systems within the plant serve to control, collect, process, handle, store, recycle, and dispose of liquid radioactive waste generated as a result of normal plant operation, including anticipated operational occurrences. This section discusses the design and operating features and performance of the liquid radwaste system and the performance of other liquid waste management systems which are discussed in other sections.

11.2.1 DESIGN BASES 11.2.1.1 Safety Design Basis Except for two containment penetrations and the component cooling water side of the reactor coolant drain tank heat exchanger, the liquid radwaste system (LRWS) is not a safety-related system.

SAFETY DESIGN BASIS ONE - The containment isolation valves in the LRWS are selected, tested, and located in accordance with the requirements of 10 CFR 50, Appendix A, GDC-56, and 10 CFR 50, Appendix J, Type C testing.

11.2.1.2 Power Generation Design Bases POWER GENERATION BASIS ONE - The LRWS, in conjunction with other liquid waste management systems, is designed to meet the requirements of the discharge concentration limits of 10 CFR 20 and the ALARA dose objective of 10 CFR 50, Appendix I.

POWER GENERATION DESIGN BASIS TWO - The LRWS uses design and fabrication codes consistent with quality group D (augmented), as assigned by Regulatory Guide 1.143, for radioactive waste management systems.

POWER GENERATION DESIGN BASIS THREE - Liquid effluent discharge paths are monitored for radioactivity.

11.2.2 SYSTEM DESCRIPTION 11.2.2.1 General Description This section describes the design and operating features of the LRWS. The performance of the LRWS, in conjunction with other liquid waste management systems, is discussed in Section 11.2.3. Detailed descriptions of other liquid waste management systems are provided in the following sections:

a. Boron recycle 9.3.6

b. Steam generator blowdown 10.4.8 11.2-1 Rev. OL-23 6/18

CALLAWAY - SP

c. CVCS boron thermal regeneration and purification 9.3.4

d. Secondary liquid waste 10.4.10 The piping and instrumentation diagram for the LRWS is shown in Figure 11.2-1.

The LRWS collects, processes, and discharges water entering the system. Equipment drains and waste streams are normally segregated to prevent the intermixing of the liquid wastes. The LRWS is capable of processing plant effluent for recycling reactor grade water, however, normally no tritiated water is transferred to the Reactor Makeup Water Storage Tank (RMWST). This method of operation prevents the contamination of Secondary systems due to deoxygenating the Reactor Makeup Water System (BL) water using the Demineralized Water Makeup Storage and Transfer System (AN).

The LRWS consists of five waste collection subsystems and three waste processing subsystems:

a. tritiated waste (CRW) drain subsystem

b. potentially radioactive nontritiated waste (DRW) drain subsystem

c. the Reactor Coolant Drain Tank subsystem (RCDT)

d. the Chemical Waste subsystem

e. the Laundry Waste subsystem

f. the Liquid Radwaste Treatment subsystem (LRWTS)

g. the Alternate Liquid Radwaste Treatment subsystem

h. the Discharge Monitor Tank subsystem Tritiated wastes (CRW), potentially radioactive nontritiated waste (DRW) and laundry waste drainage are discussed in Section 9.3.3.

The various waste streams are processed as follows:

CRW SUBSYSTEM INFLUENTS - The CRW system processes all water that can be recycled. The CRW influents consist of reactor coolant which has been exposed to the atmosphere and has become aerated. This waste consists of equipment drains, leakoffs, and overflows from tritiated systems (e.g., CVCS and reactor coolant samples which have not been chemically contaminated).

11.2-2 Rev. OL-23 6/18

CALLAWAY - SP This waste is typically collected in the floor and equipment drain system and then transferred to the waste holdup tank. CRW influents are normally processed using the LRWTS and discharged from the plant.

DRW SUBSYSTEM INFLUENTS - DRW influents are miscellaneous liquid wastes collected by the floor drain system within the radiologically controlled areas of the plant.

The controlled access areas are radiation zones B through E and include the containment, auxiliary building, fuel building, radwaste building, and the access control areas of the control building.

Floor drainage consists of miscellaneous leakage from systems within the above areas.

Generally, the amount of highly radioactive reactor coolant leakage into the drain system is very small. The bulk of the water originates as leakage from nonradioactive or slightly radioactive systems, such as the service water and component cooling water systems.

In addition to system leakage, the floor drain systems will collect decontamination water used for area washdowns, spent fuel cask decontamination, and laboratory equipment decontamination and rinses. Highly chemically contaminated decontamination solutions are normally not allowed to enter the floor drain system. During maintenance, equipment drains from nontritiated systems will normally be directed to the floor drain system.

Large volumes of component cooling water will not normally be drained to the floor drain system to prevent contamination of the LRWS by corrosion inhibitors. DRW influents are collected in two floor drain tanks and are normally processed using the LRWTS and discharged from the plant.

REACTOR COOLANT DRAIN TANK WASTE (RCDT) - Sources of water entering the reactor coolant drain tank include the reactor vessel flange leakoff, valve leakoffs, reactor coolant pump number two seal leakoffs, and the excess letdown heat exchanger flow. No continuous leakage is expected from the reactor vessel flange during operation.

The tank is provided with a hydrogen cover gas to minimize dissolved air or nitrogen buildup in the GRWS. This water may be transferred to the Recycle Holdup Tanks and processed with the Boron Recycle System or transferred to the Waste Holdup tank for processing and discharge.

HIGH LEVEL CHEMICAL WASTE - High level chemical waste consists of plant samples which have been chemically contaminated. These wastes are collected in the chemical drain tank where pH adjustment is possible. These wastes are normally drained to the floor drain system for processing.

LAUNDRY AND PERSONNEL DECONTAMINATION WASTE - Laundry waste is generated by the washing of radioactively contaminated protective clothing and gear for reuse. The personnel decontamination waste contains detergents (inorganics) and/or soaps (organics) used by personnel to remove low level radioactive contamination. The hot showers (Men's shower and Decon shower) in the access control area are used occasionally for personal use and for personnel decontamination when needed.

11.2-3 Rev. OL-23 6/18

CALLAWAY - SP Personnel decontamination wastes are collected in the detergent waste subsystems detergent drain tank and then transferred to the laundry and hot shower tanks. Laundry waste is collected in the sump located in the Laundry Decontamination Facility and then transferred over to the laundry and hot shower tanks. The waste is then processed and discharged.

The various radwaste processing systems are described as follows:

LIQUID RADWASTE TREATMENT SYSTEM (LRWTS) - The liquid radwaste treatment system consists of a vendor supplied skid containing a chemical injection system along with a series of demineralizer vessels. The vessels may be operated in any combination or with any treatment media required to process the waste water effectively. Waste water from the CRW and DRW is processed through the components of the LRWTS on an as needed basis to remove the contaminants of concern. Influents to the boron recycle system and RCDT system may be processed with the LRWTS if the recycling of reactor coolant is not desired. Also waste water collected in the laundry and hot shower tanks may be processed through this equipment. The secondary liquid waste monitor tanks normally provide a holdup capacity and the ability to recirculate and sample process stream effluent prior to transferring the processed water to the Discharge Monitor Tanks for discharge.

ALTERNATE LIQUID RADWASTE TREATMENT SYSTEM - During situations when the LRWTS is not available, the floor drain tanks and waste holdup tank may be processed by a backup means. The alternate liquid radwaste treatment system consists of a series of filters, demineralizers, charcoal adsorbers and monitor tanks. Waste water from the CRW and DRW system can be processed through these components on an as need basis to remove contaminates of concern. Intermediate monitoring tanks provide a holdup capacity and the ability to recirculate and sample process steam effluent prior to transferring the processed water to the Discharge Monitor Tanks.

DISCHARGE MONITOR TANKS - The Discharge Monitor Tanks receive effluents from the LRWTS, Alternate Liquid Radwaste Treatment system, Laundry Waste system and the Secondary Liquid Waste system. The DMTs provide for a final holdup and processing to ensure the effluent quality of the waste water is acceptable for discharge to the environment.

Modifications to the Radwaste Systems such as the addition of the LRWS have resulted in the obsolescence of various radwaste equipment and components that are currently installed and pending formal retirement. Operating procedures that govern this equipment have been updated to ensure operation of the obsolete equipment does not occur. Obsolete radwaste equipment/components, along with the equipment identification numbers, system status, and associated FSAR figures, are listed below.

The LRWS is designed and constructed in accordance with quality group D (augmented).

The LRWS is housed within a seismically designed building. Regulatory Guide 1.143 is complied with to the extent specified in Table 3.2-5. All tanks which contain or may contain concentrations of radioactivity have provisions to prevent the uncontrolled release of the fluid. Table 11.2-2 indicates the provisions made for each tank.

REACTOR COOLANT DRAIN TANK PUMPS - Due to the relative inaccessibility of the containment and the loop drain requirements, two pumps are provided. One pump provides sufficient flow for normal tank operation with one pump for standby.

WASTE EVAPORATOR FEED PUMP - One standard pump is used. The waste evaporator feed pump transfers water from the waste holdup tank to the LRWTS or the alternate LRWTS for processing. The pump is shut off when low level is reached in the waste holdup tank.

WASTE EVAPORATOR CONDENSATE TANK PUMP - The waste evaporator condensate tank pump is a transfer pump. One standard pump is used to transfer the contents of the waste condensate tank.

CHEMICAL DRAIN TANK PUMP - One standard pump can be used to recirculate the liquid in the chemical drain tank.

11.2-5 Rev. OL-23 6/18

CALLAWAY - SP LAUNDRY AND HOT SHOWER TANK PUMP - One standard pump will be used to transfer contents of each L&HST.

FLOOR DRAIN TANK PUMPS - Two standard pumps transfer water from the floor drain tanks to the LRWTS or the alternate LRWTS for processing. The pumps are cross-connected to the pump from either floor drain tank.

WASTE MONITOR TANK PUMPS - One standard pump is to be used for each tank to transfer water. The pump may also be used for circulating the water in the waste monitor tank in order to obtain uniform tank contents and hence a representative sample before discharge. The pump can be throttled to achieve the desired discharge rate.

ACID METERING PUMP - One positive displacement chemical feed pump used to inject sulfuric acid into the discharge monitor tank discharge for pH control.

CAUSTIC METERING PUMP - One positive displacement chemical feed pump used to inject sodium hypochlorite into the discharge monitor tank discharge for pH control.

REACTOR COOLANT DRAIN TANK HEAT EXCHANGER - The reactor coolant drain tank heat exchanger is a U-tube type with one shell pass and two tube passes. Although the heat exchanger is normally used in conjunction with the reactor coolant drain tank, it can also cool the pressurizer relief tank from 200 to 120°F in less than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.

REACTOR COOLANT DRAIN TANK - One tank is provided to collect leakoff type drains inside the containment at a central collection point for further disposition through a single penetration via the reactor coolant drain tank pumps.

Only water which can be directed to the recycle holdup tanks enters the reactor coolant drain tank. The tank is provided with a hydrogen cover gas. The water must be compatible with reactor coolant.

Sources of water entering the reactor coolant drain tank include the reactor vessel flange leakoff, valve leakoffs, reactor coolant pump number two seal leakoffs, and the excess letdown heat exchanger flow. No continuous leakage is expected from the reactor vessel flange during operation.

WASTE HOLDUP TANK - One atmospheric pressure tank is provided outside the containment to collect equipment drainage, valve and pump seal leakoffs, recycle holdup tank overflows, and other water from tritiated, aerated sources.

WASTE EVAPORATOR CONDENSATE TANK - One tank is provided to collect processed waste water from the LRWTS or the Alternate LRWTS.

11.2-6 Rev. OL-23 6/18

CALLAWAY - SP CHEMICAL DRAIN TANK - One tank is provided to collect chemically contaminated tritiated water from the laboratories.

LAUNDRY AND HOT SHOWER TANK - Two atmospheric tanks are used to collect laundry and hot shower drainage.

FLOOR DRAIN TANKS - Two atmospheric pressure tanks are used to collect floor drainage from the reactor plant operations.

WASTE MONITOR TANKS - The two atmospheric waste monitor tanks are provided to aid in processing or storing waste water from the LRWTS or the Alternate LRWTS.

DISCHARGE MONITOR TANKS - The two atmospheric discharge monitor tanks are provided for collecting, storing, and monitoring liquid discharges from the plant site.

WASTE EVAPORATOR CONDENSATE DEMINERALIZER - One demineralizer is provided to remove ionic contaminants from the waste being processed.

LIQUID WASTE CHARCOAL ADSORBER - One charcoal adsorber is provided to remove organics from the waste being processed. The charcoal adsorber also has the capability of being loaded with a specific resin to aid in processing.

WASTE MONITOR TANK DEMINERALIZER - One demineralizer is provided to remove trace ionic contaminants from the waste being processed.

FILTERS - Most of the filters provided are of a disposable-type cartridge. However, four filters used for processing laundry and hot shower waste are of the disposable bag filter type.

The methods employed to change filters and screens are dependent on activity levels.

Filters are valved out of service, drained to the appropriate tank, and vented locally. If the radiation level of the filter is low enough, it is changed manually.

STRAINERS - Strainers are provided in the discharge of the floor drain tank pumps to remove large particulate matter and thus prevent clogging of the downstream lines and filters.

System Operation The LRWS operation is manually initiated, except for some functions of the reactor coolant drain subsystem. The system includes adequate control equipment to protect the system components and instrumentation and alarm functions to provide operator information to ensure proper system operation. All pumps in the system have low level shutoffs, and all filters, strainers, and demineralizers have differential pressure indication to indicate fouling.

11.2-7 Rev. OL-23 6/18

CALLAWAY - SP Operation of the LRWS is essentially the same during all phases of normal reactor plant operation; the only differences are in the load on the system. The following sections discuss the operation of the system in performing its various functions. In this discussion, the term "normal operation" should be taken to mean all phases of operation, except operation under emergency or accident conditions. The LRWS is not regarded as a safety-related system.

CRW SUBSYSTEM OPERATION - Waste is accumulated in the waste holdup tank until a sufficient quantity exists to process. Normally the waste holdup tank is recirculated and sampled prior to being processed. Chemistry of the tank may be adjusted to ensure optimum system performance. Normally the waste holdup tank is processed utilizing the LRWTS. If the LRWTS is not available, the capability exists to process the waste holdup tank with the alternate liquid radwaste treatment system. If necessary, caustic or acid solution may be added to the waste water by caustic or acid metering pumps to bring the pH into allowable discharge specifications.

DRW SUBSYSTEM OPERATION - Normally one floor drain tank is aligned to receive the discharge from the floor drain system while the other tank is being used to supply waste to the processing system. This procedure allows the waste to be sampled and pH adjusted, if desired, prior to processing, to ensure optimum system performance. The second floor drain tank also provides additional system storage capacity during periods of abnormal waste generation or equipment outages. The floor drain tanks are normally processed through the floor drain tank filter to the LRWTS. If the LRWTS is not available, the capability exists to process the floor drain tanks with the alternate liquid radwaste treatment system.

REACTOR COOLANT DRAIN TANK SUBSYSTEM OPERATION - Normal operation of the reactor coolant drain subsystem is in the manual mode. Due to the small amount of leakage into the system, less wear and tear on the equipment is experienced by maintaining it in the manual mode. The tank level is monitored by the radwaste operators and pumped out when necessary. The leakage rate of reactor coolant pump No. 2 seal leakoffs, reactor vessel flange leakoffs, valve stem leakoffs and discharges from the excess letdown heat exchanger into the reactor coolant drain tank (RCDT) can be estimated by leaving the system in manual mode and watching the rate of level change. This will measure the identified leakage. The reactor coolant drain tank pumps normally discharge to the boron recycle system. These drains can also be aligned to the waste holdup tank. When in the automatic mode, the level in the RCDT is maintained by running one RCDT pump continuously and using a proportional control valve (LCV-1003) in the discharge line. This valve operates on a signal from the RCDT level controller to limit the flow out of the subsystem. The remainder of the flow is recirculated to the RCDT. The RCDT heat exchanger is sized to maintain the RCDT contents at or below 170°F, assuming an in-leakage of 10 gpm at 600°F.

A venting system is provided to prevent wide pressure variations in the RCDT. Normally, the pressure in the RCDT is manually controlled by raising/lowering level in the tank. If too much pressure has built up in the RCDT and cannot be controlled by lowering the 11.2-8 Rev. OL-23 6/18

CALLAWAY - SP tank level, manual valves can be opened to the gaseous radwaste system to lower the pressure in the RCDT. The manual valves may also be operated to raise the tank's cover gas pressure as needed. Hydrogen cover gas is supplied from the service gas system and can be automatically maintained between 2 and 6 psig by pressure regulating valves. PCV-7155 maintains a minimum tank pressure by admitting hydrogen, while PCV-7152 maintains maximum tank pressure by venting the RCDT to the gaseous radwaste system, thereby limiting any releases of radioactive gases. The hydrogen is supplied from no more than two 194 SCF bottles in order to limit the amount of hydrogen gas that could be accidentally released to the containment atmosphere. Provisions are made to permit the gas in the tank to be periodically analyzed to monitor for the presence of oxygen. If purging of RCDT becomes necessary, a supply of nitrogen gas may be established and delivered to the RCDT via PCV-7155 (refer to Section 9.3.5.2.1).

The reactor coolant drain subsystem may also be used in the pressurizer relief tank (PRT) cooling mode of operation. In this mode, the level control valve in the discharge line to the recycle evaporator feed demineralizers (LCV-1003), the isolation valve at the discharge of the reactor coolant drain tank (HV-7127), and the isolation valve in the reactor coolant drain tank recirculation line (HV-7144) are all closed. The PRT contents are circulated through the reactor coolant drain tank heat exchanger, via valve BB-HV-8031 and the reactor coolant drain tank pumps, prior to returning to the PRT via valve BB-HV-7141. In this mode of operation, the RCDT heat exchanger is capable of cooling the PRT contents from 200°F to 120°F in less than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. As an alternative to returning the cooled fluid to the PRT, the fluid may be directly transferred to the recycle holdup tanks in the boron recycle system. In either case, the PRT is vented to less than 50 psig to prevent overpressurization of the RCDT subsystem.

The reactor coolant drain subsystem may be used to drain the reactor coolant loops by first venting the reactor coolant system, then connecting the spool piece in the RCDT pump suction piping. The design objective of this mode of operation is to drain the RCS to the midpoint of the reactor vessel nozzles in less than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> with both RCDT pumps running. In this mode, valve HV-7144 is closed and, in order to maximize flow capability, the RCDT discharge level control valve (LCV-1003) should be bypassed during RCS draining operations.

The reactor coolant drain subsystem may be used to drain down portions of the refueling pool which cannot be drained by the residual heat removal pumps. In this mode of operation, the RCDT heat exchanger may be bypassed and the RCDT level control valve (LCV-1003) may be bypassed to maximize flow through the fuel pool cooling and cleanup system to the refueling water storage tank. An alternate drain line is provided from the refueling pool to the containment sump to route decontamination chemicals away from the RCDT subsystem and minimize the possibility of contaminating any systems downstream of the RCDT pumps.

CHEMICAL WASTE - The chemical drain tank (CDT) receives chemically contaminated tritiated water from the plant sample stations. Contents of the tank are sampled, and 11.2-9 Rev. OL-23 6/18

CALLAWAY - SP normally drained to the floor drain system. Operation is intermittent and manually controlled. A high level alarm is provided from the CDT for operator information.

LAUNDRY SUBSYSTEM OPERATION - Waste water from the Deep sinks, a washing machine, Men's shower and the personnel decontamination shower are directed by gravity drain to the detergent drain tank located in the basement of the control building and then is pumped to the laundry and hot shower tanks (L&HSTs). Laundry waste from the washers and the dryers located in the Laundry Decontamination Facility are collected in the building sump and also pumped over to the L&HSTs. The L&HST fluid is low in radioactivity and is normally processed by the L&HST bag filters. The waste may be directed to waste monitor tank "B" and subsequently to the discharge monitor tanks for discharge or directly to the discharge monitor tanks.

The laundry system requires makeup water that is normally from a radiologically "clean" source (i.e., Potable water) because water is taken from the system in wet clothes, evaporated in the dryers, and vented from the plant. Potable water will be connected to an OZONE generator, which will provide the bulk of the cleaning agent for the washing machines. Ozone cleans by breaking down the organic molecules in the water and is more effective than chlorine in killing bacteria and reduces or eliminates the need for detergents. Since Ozone requires little or no detergent, there are less residual chemicals in the fabrics after the rinse cycle and fewer rinse cycles are needed. The laundry water is then pumped, on demand of the washing machines, to the laundry equipment in operation. Although the ozone works best in cold water, one washing machine will be equipped with a steam heating system if hot water might be needed. In all phases of laundry operation, the operator must take care to use detergents, soaps, and additives that are compatible with waste processing equipment.

DISCHARGE MONITOR TANKS - Normally one discharge monitor tank is aligned to receive plant waste while the other tank is being prepared for discharge. Waste is accumulated until a sufficient quantity exists for processing. The tank is isolated, recirculated, sampled and permitted prior to discharge. The capability exists to reprocess or adjust tank chemistry as necessary to ensure environmental effluent requirements are met. The second discharge monitor tank also provides additional system storage capacity during periods of abnormal waste generation.

The LRW system is designed to handle the occurrence of equipment faults of moderate frequency such as:

a. Malfunction in the LWRS Malfunction in this system could include such things as pump or valve failures. Because of pump standardization throughout the system, a spare pump can be used to replace most pumps in the system. There is sufficient surge capacity in the system to accommodate waste until the failures can be fixed and normal plant operation resumed.

11.2-10 Rev. OL-23 6/18

CALLAWAY - SP

b. Excessive leakage in reactor coolant system equipment The system is designed to handle a 1-gpm reactor coolant leak in addition to the expected leakage of 50 lb/day (Ref. 1) during normal operation, which is discussed in Section 5.2.5. Operation of the system is almost the same for normal operation, except that the load on the system is increased.

A 1-gpm leak into the reactor coolant drain tank is handled automatically but will increase the load factor of the recycle system. If the gpm leak enters the waste holdup tank, operation is the same as normal, except for the increased load on the system. Abnormal liquid volumes of reactor coolant resulting from excessive reactor coolant or auxiliary building equipment leakage (in excess of 1 gpm) can also be accommodated by the floor drain tank and processed by the LRWTS. Valve and pump leakoffs containing recyclable water are recycled through the waste holdup tank.

c. Excessive leakage in the auxiliary system equipment Leakage of this type could include water from steam side leaks and fan cooler leaks inside the containment which are collected in the containment sump and sent to the floor drain tank. Other sources could be component cooling water leaks, service water leaks, and secondary side leaks. This water will enter the floor drain tank and will be processed and discharged as during normal operation.

11.2.3 RADIOACTIVE RELEASES This section describes the estimated liquid release from the plant for normal operation and anticipated operational occurrences.

11.2.3.1 Sources Section 11.1 and Appendix 11.1A provide the bases for determining the contained sources inventory and the normal releases.

A survey has been performed of liquid discharges from different Westinghouse pressurized water reactor plants. The results are presented in Table 11.2-17 of Reference 2. The data includes radionuclides released on an unidentified basis, and are all within the permissible concentration for the release of liquid containing all unidentified radionuclide mixtures.

11.2.3.2 Release Points Refer to Section 11.2.3.2 of the Site Addendum.

11.2-11 Rev. OL-23 6/18

11.2.3.4 Estimated Doses Refer to Section 11.2.3.4 of the Site Addendum.

11.2.4 SAFETY EVALUATION Except for two associated containment penetrations and the CCW pressure boundary integrity at the reactor coolant drain tank, the LRWS is not a safety-related system.

SAFETY EVALUATION ONE - Sections 6.2.4 and 6.2.6 provide the safety evaluation for the system containment isolation arrangement and testability.

11.2.5 TESTS AND INSPECTION Preoperational testing is discussed in Chapter 14.0.

The operability, performance, and structural and leaktight integrity of all system components are demonstrated by intermittent or continuous operation.

11.2.6 INSTRUMENTATION DESIGN The system instrumentation is described in Table 11.2-3 and shown on Figure 11.2-1.

The instrumentation readout is located mainly on the waste processing system panel in the radwaste building. Some instruments are read locally.

All alarms are shown separately on the waste processing system panel.

The waste processing system pumps are protected against loss of suction pressure by a control setpoint on the level instrumentation for the respective vessels feeding the pumps. The reactor coolant drain tank pumps and the spent resin sluice pump are, in addition, interlocked with flow rate instrumentation and stop operating when the delivery flows reach minimum setpoints.

Differential pressure indicators with local readout are provided for filters, strainers, and demineralizers.

CALLAWAY - SP 11.3 GASEOUS WASTE MANAGEMENT SYSTEMS The gaseous radwaste system (GRWS) and the plant ventilation exhaust systems control, collect, process, store, and dispose of gaseous radioactive wastes generated as a result of normal operation, including anticipated operational occurrences. This section discusses the design, operating features, and performance of the GRWS and the performance of the ventilation systems. The plant ventilation exhaust systems accommodate other potential release paths for gaseous radioactivity due to miscellaneous leakages, aerated vents from systems containing radioactive fluids, and the removal of noncondensables from the secondary system. Systems which handle these gases are not normally considered gaseous waste systems and are discussed in detail in other sections. These systems are included here to the extent that they represent potential release paths for gaseous radioactivity.

11.3.1 DESIGN BASES 11.3.1.1 Safety Design Basis The GRWS and other gaseous waste management systems serve no safety-related function.

11.3.1.2 Power Generation Design Bases POWER GENERATION DESIGN BASIS ONE - The GRWS and the ventilation exhaust systems are designed to meet the requirements of the discharge concentration limits of 10 CFR 20 and the as low as reasonably achievable dose objective of 10 CFR 50, Appendix I.

POWER GENERATION DESIGN BASIS TWO - The GRWS includes design features to preclude the possibility of an explosion where a potential for an explosive mixture exists.

POWER GENERATION DESIGN BASIS THREE - The GRWS uses design and fabrication codes consistent with quality group D (augmented), as assigned by Regulatory Guide 1.143 for radioactive waste management systems.

POWER GENERATION DESIGN BASIS FOUR - The ventilation exhaust system complies with Regulatory Guide 1.140 to the extent specified in Table 9.4-3.

POWER GENERATION DESIGN BASIS FIVE - Gaseous effluent discharge paths are monitored for radioactivity.

11.3-1 Rev. OL-23 6/18

CALLAWAY - SP 11.3.2 SYSTEM DESCRIPTIONS 11.3.2.1 General Description This section describes the design and operating features of the GRWS. The performance of the GRWS and other plant gaseous waste management systems with respect to the release of radioactive gases is discussed in Section 11.3.3. Detailed descriptions of the plant ventilation systems and main condenser evacuation system are presented in Sections 9.4 and 10.4.2, respectively.

The piping and instrumentation diagram for the GRWS is shown in Figure 11.3-1.

The main flow path in the GRWS is a closed loop comprised of two waste gas compressors, two catalytic hydrogen recombiners, six gas decay tanks for normal power service, and two gas decay tanks for service at shutdown and startup. The system also includes a gas decay tank drain collection tank, drain pump, four gas traps to handle normal operating drains from the system, and a waste gas drain filter to permit maintenance and handle normal operating drains from the system. All of the equipment is located in the radwaste building.

The closed loop has nitrogen for a carrier gas. The primary influents to the GRWS are combined with hydrogen as the stripping or carrier gas. The hydrogen that is introduced to the system is recombined with oxygen, and the resulting water is removed from the system. As a result, the bulk of all influent gases is removed, leaving trace amounts of inert gases, such as helium and radioactive noble gases to build up.

The primary source of the radioactive gas is via the purging of the volume control tank with hydrogen, as described in Section 9.3.4. The operation of the GRWS serves to reduce the fission gas concentration in the reactor coolant system which, in turn, reduces the escape of fission gases from the reactor coolant system during maintenance operations or through equipment leakage. Smaller quantities are received, via the vent connections, the reactor coolant drain tank, the pressurizer relief tank, and the recycle holdup tanks.

Since hydrogen is removed in the recombiner, this gas does not build up within the system. The largest contributor to the nonradioactive gas accumulation is helium generated by a B10(n,a)Li7 reaction in the reactor core. The second largest contributors are impurities in the bulk hydrogen and oxygen supplies. Stable and long-lived isotopes of fission gases also contribute small quantities to the system gas volume accumulation.

Operation of the system is such that fission gases are distributed throughout the six normal operation gas decay tanks. Separation of the GRWS gaseous inventory in several tanks assures that the allowable site boundary dose will not be exceeded in the event of a gas decay tank rupture. Radiological consequences of such a postulated rupture are discussed in Section 15.7.1.

11.3-2 Rev. OL-23 6/18

CALLAWAY - SP The GRWS also provides the capacity for indefinite holdup of gases generated during reactor shutdown. Nitrogen gas from previous shutdowns is contained in one of the shutdown gas decay tanks for use in stripping hydrogen from the reactor coolant system.

The second shutdown tank is normally at low pressure and is used to accept relief valve discharges from the normal operation gas decay tanks.

For all buildings where there is potential airborne radioactivity, the ventilation systems are designed to control the release. Where applicable, each building has a vent collection system for tanks and other equipment which contains air or aerated liquids.

The condenser evacuation system discharge is filtered and discharged to the unit vent in addition to the discharges from the reactor building, auxiliary building, and fuel building.

The radwaste building, which houses the GRWS, has its own release vent. The turbine building has an open ventilation system, and the steam packing exhaust discharges into the turbine building.

The vent collection systems receive the discharge of vents from tanks and other equipment in the radwaste and auxiliary buildings which contain air or aerated liquids.

These components contain only a very small amount of fission product gases. Prior to release via the radwaste or auxiliary building ventilation system, the gases are monitored, as described in Section 11.5, and passed through a prefilter, HEPA filter, charcoal filter, and another HEPA filter in series which reduce any airborne particulate radioactivity to negligible levels and provide a decontamination factor of at least 10 for radioactive iodines and 100 for particulates. Expected efficiencies for iodine removal are better than 99 percent for elemental iodine and 95 percent for organic iodine at 70-percent relative humidity. However, for gaseous effluent release calculations, 70-percent efficiency is conservatively used for radioiodine isotopes.

Although plant operating procedures, equipment inspection, and preventive maintenance are performed during plant operations to minimize equipment malfunction, overall radioactive release limits have been established as a basis for controlling plant discharges during operation with the occurrence of a combination of equipment faults of moderate frequency. These faults include operation with fuel defects in combination with steam generator tube leaks and malfunction of liquid or gaseous waste processing systems or excessive leakage in reactor coolant system equipment or auxiliary system equipment. Operational occurrences such as these can result in the discharge of radioactive gases from various plant systems. These unscheduled discharges may be from plant systems which are not normally considered gas processing systems or from a gas decay tank after a 60-day holdup period. If the holdup period restricts plant operation, it may be necessary to decrease this time with prior approval from the Manager, Radiation Protection. These potential sources are tabulated in Table 11.1-2.

The bases for assumed releases, the factors which tend to mitigate the release of radioactivity, and the release paths are given in Appendix 11.1A.

A further discussion of the gaseous releases from the plant is provided in Section 11.3.3.

11.3-3 Rev. OL-23 6/18

CALLAWAY - SP 11.3.2.2 Component Description Codes and standards applicable to the GRWS are listed in Tables 3.2-1 and 11.3-1. The GRWS is designed and constructed in accordance with quality group D (augmented).

The GRWS is seismically designed, as discussed in Table 3.2-5. The GRWS is housed within a seismically designed building. The GRWS design complies with Regulatory Guide 1.143, as specified in Table 3.2-5.

WASTE GAS COMPRESSOR - The waste gas compressor is a water-sealed centrifugal displacement unit which maintains continuous circulation of nitrogen around the waste gas loop. The compressor is provided with a mechanical shaft seal to minimize water leakage. The compressor moisture separator normal water level is maintained to keep the shaft immersed at all times.

Two waste gas compressor packages are provided. One compressor is normally used, and the other compressor is on standby. The packages are self-contained and skid-mounted. Construction is primarily of carbon steel.

CATALYTIC HYDROGEN RECOMBINER - The catalytic recombiner disposes of hydrogen brought into the GRWS. This is accomplished by adding a controlled amount of oxygen to the recombiner which reacts with the hydrogen as the gas flows through a catalyst bed. The control system for the recombiner is designed to preclude the possibility of a hydrogen explosion. This is further discussed in Section 11.3.6.

Two hydrogen recombiner packages are provided. One recombiner is normally used, and the other is on standby. The packages are self-contained and skid-mounted. The recombiner is located in the system where the hydrogen concentration and pressure are optimum with respect to hydrogen removal.

DECAY TANK - Eight gas decay tanks are provided, six for normal power operation and two for service at shutdown and startup. The tanks are of the vertical-cylindrical type and are constructed of carbon steel.

MISCELLANEOUS COMPONENTS - The gas decay drain collection tank provides a collection point for condensation drained from the gas decay tanks, recombiners, and gas compressors.

All control valves, with the exception of those on the recombiner, are provided with bellow seals to minimize the leakage of radioactive gases through the valve bonnet and stem. Valves on the recombiner package are provided with leakoffs.

Relief valves have soft seats and are exposed to pressures which are normally less than two-thirds of the relief valve set pressure. The relief valves of the major components discharge to the shutdown tanks. This permits decay and controlled disposal of all discharges less than about 3,000 scf. The relief valves are designed to relieve full flow from both waste gas compressors.

11.3-4 Rev. OL-23 6/18

CALLAWAY - SP To maintain leakage from the system at the lowest practicable level, diaphragm-type manual valves are used throughout the waste gas system. For low temperature, low pressure service valves with a synthetic rubber-type diaphragm are used. This application includes all parts of the system, except the recombiners. Because of the high temperature that may exist in the recombiner, globe type valves with a metal diaphragm seal in the stem are used. There should be no measurable stem leakage from either type of valve.

The gas decay tank drain pump directs water from the gas decay drain collection tank (due to condensation or maintenance) to the waste holdup tank or recycle holdup tanks.

It is used when there is insufficient pressure in the gas system to drive the fluid. All parts of the pump in contact with the drain water are of austenitic stainless steel. The pump is a canned-motor type.

The waste gas drain filter is a disposable cartridge filter provided to prevent particulate matter, including rust, larger than 30 microns from entering the LRWS and BRS. All parts of the filter in contact with the drain water are of austenitic stainless steel.

The waste gas traps are designed to prevent gases from leaving the GRWS. There are four gas traps - two in the gas decay tank drain line and one each in the recombiner drain lines and compressor drain lines.

The component description for the ventilation systems is provided in Section 9.4.

11.3.2.3 System Operation Operation of the ventilation systems is described in Section 9.4. The following is a description of the GRWS.

NORMAL OPERATION - The GRWS system is normally operated when increased fission gases or excess hydrogen levels have accumulated in the volume control tank (VCT). When needed, nitrogen gas, with contained fission gases, is circulated around the GRWS loop by one of the two compressors. Fresh hydrogen gas is introduced into the VCT where it is mixed with fission gases stripped from the reactor coolant by the action of the VCT letdown line spray nozzle. The gas is vented from the VCT into the circulating nitrogen in the waste gas system, at the compressor suction.

The resulting mixture of nitrogen, hydrogen, and fission gases is pumped by one of the compressors to one of the two catalytic hydrogen recombiners where enough oxygen is added to react with and reduce the hydrogen to a low residual level. Water vapor formed in the recombiner by the hydrogen and oxygen reaction is condensed and removed, and the cooled gas stream (now composed primarily of nitrogen, helium, and fission gases) is discharged from the recombiner, routed through a gas decay tank, and sent back to the compressor suction to complete the loop circuit.

Only one gas decay tank is valved into the waste gas loop at any time.

11.3-5 Rev. OL-23 6/18

CALLAWAY - SP If it has been determined that excessive nitrogen buildup is occurring within the system or when other occurrences require it, one tank can be valved out of service and allowed to decay for a period of 60 days. If the holdup time restricts plant operation, it may be necessary to decrease this time with prior approval from the Manager, Radiation Protection.

STARTUP - At plant startup, the system is first flushed free of air and filled with nitrogen at atmospheric pressure. One compressor, one recombiner, and one shutdown decay tank are in service. The reactor is at the cold shutdown condition. Fresh hydrogen is charged into the volume control tank, and the volume control tank vent gas mixes with the circulating nitrogen in the GRWS. This circulating mixture enters the compressor suction, passes through the recombiner and shutdown gas decay tank, and returns to the compressor suction. When the reactor coolant system hydrogen concentration is within operating specifications, the shutdown gas decay tank is isolated and the gas flow directed to one of the gas decay tanks provided for normal power operation. Gases accumulated in the shutdown tank will be retained for reuse during hydrogen stripping from the reactor coolant system during subsequent shutdown operations.

SHUTDOWN AND DEGASSING OF THE REACTOR COOLANT SYSTEM - Plant shutdown operations are essentially startup operations in reverse sequence. During normal power operations a hydrogen purge is maintained on the VCT. Before initiating a cold shutdown (refer to FSAR 9.3.4.2.3.3), a nitrogen purge to the VCT is begun from the nitrogen header or from a shutdown gas decay tank. A gas decay tank is placed in the process loop so that the gas mixture from the VCT vents to the GRW system and passes through to the recombiner where hydrogen is removed. The volume control tank nitrogen purge is maintained until hydrogen and coolant fission gas concentrations have been reduced to specified levels. During this operation, nitrogen purge flow may be increased to speed up coolant degassing. During degas operations, the inlet hydrogen analyzer may be bypassed to facilitate hydrogen removal. Technical Specifications provide the limits to follow during analyzer operations. The nitrogen purge continues until the reactor coolant hydrogen concentration reaches the required level. Degassing is then complete, and the reactor coolant system may be opened for maintenance or refueling.

An alternative method to degas the reactor coolant system may also be employed. This method, chemical degassing, reduces the reactor coolant dissolved hydrogen concentration through reaction with hydrogen peroxide. After reactor shutdown, plant cooldown continues until RCS temperature is less than 180°F. A pre-determined quantity of hydrogen peroxide is added. The hydrogen peroxide reacts with dissolved hydrogen to form water. The reactor coolant is sampled to verify the hydrogen concentration has reached the required level. The VCT nitrogen purge may be performed in conjunction with chemical degas operations if it is desired to reduce reactor coolant system noble gas levels or to help expedite reducing the RCS hydrogen concentration.

11.3-6 Rev. OL-23 6/18

CALLAWAY - SP During RCS cooldown, the VCT, pressurizer, pressurizer relief tank (PRT), reactor coolant drain tank (RCDT), and recycle holdup tanks may have hydrogen and oxygen concentrations present. Provisions are made to permit the gas in these tanks to be periodically analyzed to monitor for the presence of a flammable/explosive atmosphere, and to vent or purge these tanks to the GRWS as necessary.

11.3.3 RADIOACTIVE RELEASES This section describes the estimated gaseous release from the plant for normal operation and anticipated operational occurrences.

11.3.3.1 Sources Section 11.1 and Appendix 11.1A provide the bases for determining the contained source inventory and the normal releases.

11.3.3.2 Release Points Potential release paths for gaseous radioactivity are illustrated schematically in Appendix 11.1A. The general location of potential gaseous radioactivity release points is depicted in Figure 1.2-1. A description of potential release points for radioactive gaseous effluents is given in Appendix 11.1A, along with the physical characteristics of the gaseous effluent streams. Release points from the gaseous waste processing systems are shown on Figure 11.3-2.

11.3.3.3 Dilution Factors The annual average dilution factors used in evaluating the release of gaseous radioactive effluents for the site are derived and justified in Section 2.3 of the Site Addendum.

11.3.3.4 Estimated Doses Table 11.3-2 gives the estimates of offsite doses from radioactive gaseous effluents for the site. Estimated doses were calculated by site consultants and reflect site characteristics, such as distance, grazing factors, and meteorology. The results shown in Table 11.3-2 demonstrate that the ALARA criteria of 10 CFR 50 are met.

For a description of assumptions and models for dose calculations, refer to Section 11.3 of the Site Addendum.

11.3.4 SAFETY EVALUATION The GRWS serves no safety-related function.

11.3-7 Rev. OL-23 6/18

CALLAWAY - SP 11.3.5 TESTS AND INSPECTIONS Preoperational testing is described in Chapter 14.0.

The operability, performance, and structural and leaktight integrity of all system components are demonstrated by intermittent or continuous operation.

11.3.6 INSTRUMENTATION APPLICATION The GRWS instrumentation, as described in Table 11.3-3, is designed to facilitate automatic operation and remote control of the system and to provide continuous indication of system parameters.

The instrumentation readout is located mainly on the waste processing system panel in the radwaste building. Some instruments are read where the equipment is located. All alarms are shown separately on the waste processing system panel. Where suitable, instrument lines are provided with diaphragm seals to prevent fission gas outleakage through the instrument. Figure 11.3-3 shows the location of the instruments on the compressor package.

The compressors are interlocked with the seal water inventory in the moisture separators and trip off on either high or low moisture separator level. During normal operation, the proper seal water inventory is maintained automatically.

Figure 11.3-4 indicates the location of the instruments on the recombiner installation.

The catalytic recombiner system is designed for automatic operation with a minimum of operation attention. Each package includes two online gas analyzers, one to measure hydrogen and oxygen in and one to measure hydrogen and oxygen out, which are the primary means of recombiner control. Each gas concentration channel of these two online gas analyzers is independently controlled.

The GRWS is designed to operate with hydrogen concentrations above 4 percent by volume. Flammable mixtures of gases in the system are prevented by monitoring and controlling the oxygen concentration to appropriate levels. The setpoints for oxygen concentration in the catalyst bed inlet stream are 3 percent for the hi alarm and 3.5 percent for the hi-hi alarm and isolation of the oxygen supply. The setpoint for oxygen concentration downstream of the catalyst bed is 60 ppm oxygen for the hi-hi alarm and isolation of inlet oxygen supply. Thus the oxygen supply to the recombiner would be terminated before the concentration in the GRWS would reach levels favorable for hydrogen flammability.

Since the GRWS is designed to operate with hydrogen concentrations up to 6 percent by volume, up to 3 percent oxygen is necessary for operation of the catalytic recombiner.

Termination of oxygen feed at 2 percent as suggested by regulatory guidance is inappropriate. Further, since the minimum oxygen concentration necessary to support 11.3-8 Rev. OL-23 6/18

CALLAWAY - SP combustion at 4 percent by volume hydrogen concentrations is 5 percent, the hi-alarm setpoint of 3 percent provides sufficient margin (i.e., 60 percent of the limit) to flammability.

A multipoint temperature recorder monitors temperatures at several locations in the recombiner packages.

The process gas flow rate is measured by an orifice located upstream of the recombiner preheater. Local pressure gauges indicate pressure at the recombiner inlet and oxygen supply pressure.

The following controls and alarms are incorporated to maintain the gas composition outside the range of flammable and explosive mixtures:

a. A high flow alarm sounds at the volume control tank purge flow corresponding to 3 percent hydrogen by volume at the inlet to the hydrogen recombiner.

b. If the recombiner feed concentration exceeds 4 percent by volume, a high-hydrogen alarm sounds. This alarm will be followed by a second alarm indicating high hydrogen in the recombiner discharge. These alarms warn of a possible Section 16.11.2.6 surveillance condition and a possible hydrogen accumulation in the system, respectively.

c. If the hydrogen concentration in the recombiner feed reaches 9 percent by volume, a high-high hydrogen alarm sounds, the oxygen feed is terminated, and the volume control tank hydrogen purge flow is terminated.

These controls limit the possible accumulation of hydrogen in the GRWS to 3 percent by volume.

d. If the oxygen concentration in the recombiner feed reaches 3 percent by volume, an alarm sounds and oxygen feed flow is limited so that no further increase in flow is possible. This control maintains the system oxygen concentration at 3 percent or less, which is below the flammable limit for hydrogen-oxygen mixtures.

e. If the oxygen concentration in the recombiner feed reaches 3.5 percent by volume, an alarm sounds and the oxygen feed flow is terminated.

f. If hydrogen in the recombiner discharge exceeds 1.25 percent by volume, an alarm sounds. This alarm warns of high hydrogen feed, possible catalyst failure, or loss of oxygen feed.

g. If oxygen in the recombiner discharge exceeds 60 ppm, an alarm sounds and oxygen feed is terminated. This control prevents any accumulation of oxygen in the system in case of hydrogen recombiner malfunction.

11.3-9 Rev. OL-23 6/18

CALLAWAY - SP

h. On low flow through the recombiner, oxygen feed is terminated. This control prevents an accumulation of oxygen following system malfunction.

i. High discharge temperature from the cooler-condenser (downstream from the reactor) will terminate oxygen feed. This protects against loss of cooling water flow in the cooler-condenser.

j. High temperature indication by any one of six thermocouples in the catalyst bed will limit oxygen feed so that no further increase is possible.

k. High temperature indication at the recombiner reactor discharge will terminate oxygen feed to the recombiner.

l. If the oxygen and hydrogen concentrations in the recombiner feed reach 3 and 4 percent respectively by volume, an alarm sounds. This alarm alerts operators to a Section 16.11.2.6 surveillance condition.

m. If the oxygen and hydrogen concentration in the recombiner feed both reach 4 percent by volume, an alarm sounds. This alarm alerts operators to a Section 16.11.2.6 recombiner shutdown condition.

CALLAWAY - SP 11.4 SOLID WASTE MANAGEMENT SYSTEM The solid radwaste system (SRS) is designed to meet the functional requirements of the solid waste management system. The SRS is designed to collect, process, and package radioactive wastes generated as a result of normal plant operation, including anticipated operational occurrences, and to store this packaged waste until it is shipped offsite to an intermediate processing facility or to a licensed burial site. The process and effluent radiological and sampling systems are described in Section 11.5.

11.4.1 DESIGN BASES 11.4.1.1 Safety Design Bases The SRS performs no function related to the safe shutdown of the plant, and its failure does not adversely affect any safety-related system or component; therefore, the SRS has no safety design bases.

11.4.1.2 Power Design Bases POWER GENERATION DESIGN BASIS ONE - The SRS is designed to meet the following objectives:

a. Provide remote transfer and hold-up capability for spent radioactive resins from the chemical and volume control system, fuel pool cooling and cleanup system, boron recycle system, liquid radwaste system, steam generator blowdown system, and secondary liquid waste system and for spent radioactive activated charcoal from the liquid radwaste system and the secondary liquid waste system.

b. Deleted

c. Provide a means to remove and transfer the spent filter cartridges from the filter vessels to the solid radwaste processing system in a manner that minimizes radiation exposure to operating personnel and the spread of contamination.

d. Deleted POWER GENERATION DESIGN BASIS TWO - The SRS is designed and constructed in accordance with Regulatory Guide 1.143, as described in Table 3.2-5, and Branch Technical Position ETSB 11-3, as described in Table 11.4-1. The seismic design classification of the radwaste building, which houses the solid waste management system, and the seismic design and quality group classification for the system components and piping are provided in Section 3.2.

11.4-1 Rev. OL-23 6/18

CALLAWAY - SP POWER GENERATION DESIGN BASIS THREE - The SRS design parameters are based on the radionuclide concentrations and volumes consistent with reactor operating experience for similar designs and with the source terms of Section 11.1.

POWER GENERATION DESIGN BASIS FOUR - Collection, solidification, packaging, and storage of radioactive wastes are to be performed so as to maintain any potential radiation exposure to plant personnel during system operation or during maintenance to "as low as is reasonably achievable" (ALARA) levels, in accordance with the intent of Regulatory Guide 8.8 in order to maintain personnel exposures well below 10 CFR 20 requirements. Design features incorporated to maintain ALARA criteria include remote system operation, remotely actuated flushing, and equipment layout permitting the shielding of components containing radioactive materials. Additionally, access to the solidification and solid waste storage areas is controlled to minimize personnel exposure.

POWER GENERATION DESIGN BASIS FIVE - The onsite storage facilities for drummed solid wastes have a capacity for temporary storage of solid wastes resulting from up to 5 years of plant operation. Temporary onsite storage and shipping offsite of solid radwaste do not present a radiation hazard to persons onsite or offsite, for either normal conditions or extreme environmental conditions, such as tornados, floods, or seismic events.

POWER GENERATION DESIGN BASIS SIX - The SRS is designed to meet the requirements of General Design Criterion 60 of 10 CFR 50, Appendix A. Packaging and shipment of radioactive wastes is performed in accordance with the requirements of 10 CFR 71, 49 CFR 173, and applicable state regulations.

11.4.2 SYSTEM DESCRIPTION 11.4.2.1 General Description The SRS consists of the following subsystems which are illustrated in the piping and instrumentation diagrams provided in Figure 11.4-1:

a. Solidification system

b. Dry waste system

c. Resin handling system

d. Filter handling system The activity of the influents to the SRS is dependent on the activities of the various fluid systems, such as the boron recycle system, secondary liquid waste system, liquid waste management system, chemical and volume control system, fuel pool cooling and cleanup system, floor and equipment drain system, and the steam generator blowdown 11.4-2 Rev. OL-23 6/18

CALLAWAY - SP system. Reactor coolant system activities and the decontamination factors for the systems given above also determine the influent activities to the solid radwaste system.

Table 11.4-2 lists the estimated expected and maximum activities of waste to be processed on an annual basis and their physical form and source. The isotopic makeup and curie contents of the expected influents to the SRS are given in Table 11.4-2. The estimated annual quantities of solid radwaste to be shipped offsite are presented in Table 11.4-3. The estimated expected and maximum curie and isotopic content of wastes to be shipped offsite for each waste category are also presented in Table 11.4-4.

Section 11.1 and Appendix 11.1A provided the bases for determination of liquid source terms which are used to calculate the solid waste source terms. The sources presented in Tables 11.4-2 and 11.4-4 are conservatively based on Section 11.1, Appendix 11.1A and the following additional information:

a. As a basis for the shipped-from-site activities given in Table 11.4-4, 30 days' decay prior to shipment is assumed.

b. The miscellaneous dry and compacted waste volume is based on Case 6 of Table 2-49 of WASH-1258, July, 1973.

c. Shipping volumes based on packaging in 55-gallon drums:

(1) 3.5 ft3 primary spent resin, primary charcoal, per drum (2) 4.8 ft3 liquid radwaste processing spent resin and charcoal per drum (3) 1 filter cartridge per drum (4) 7.5 ft3 shipped volume per drum (including cement) 11.4.2.2 Component Description Codes and standards applicable to the SRS are listed in Tables 3.2-1 and 11.4-5. The SRS is designed and constructed in accordance with requirements. The SRS is housed within a seismically designed building. Regulatory Guide 1.143 is complied with to the extent specified in Table 3.2-5.

SRS component parameters are presented in Table 11.4-5. The following is a functional description of the major system components:

SPENT RESIN STORAGE TANK (PRIMARY) - Provides for storage and decay of the spent resins from the demineralizers in the chemical and volume control system, fuel pool cooling and cleanup system, boron recycle system, and liquid radwaste system prior to dewatering processes.

11.4-3 Rev. OL-23 6/18

CALLAWAY - SP SPENT RESIN STORAGE TANK (SECONDARY) - Designed to provide for storage and decay of the spent resins and spent activated charcoal from the demineralizers and charcoal adsorbers in the steam generator blowdown system, secondary liquid waste system, and charcoal adsorbers in the liquid radwaste system prior to solidification or dewatering processes. Although designed and provided for the noted purpose, this tank is not normally used.

SPENT RESIN SLUICE PUMPS (PRIMARY AND SECONDARY) - Can provide the motive flow to transfer spent resin or spent activated charcoal from the various demineralizers or adsorbers to the appropriate spent resin storage tank. However, these pumps are not normally used.

CAUSTIC ADDITION TANK AND METERING PUMP - Provides chemistry control to the chemical drain tank, floor drain tank, waste holdup tank, and discharge monitor tanks.

RESIN CHARGING TANKS - Designed to provide remote means of gravity sluicing clean resin and activated charcoal into the demineralizer and adsorber units. Although designed and provided with the noted capability, these tanks are not normally used.

SOLID RADWASTE BRIDGE CRANE - A crane, remotely operated from the solid radwaste control console, which provides the means of moving containers from station to station in the processing area, from the processing area to the solid waste storage area, and from the solid waste storage area to the shipping area. The crane is equipped with a television camera system to facilitate the remote handling operation. This crane can also be operated with a radio controller locally.

BULK WASTE DISPOSAL STATION - Provides a means for bulk processing or disposal of wastes generated during plant operations. Process piping is provided within the installed solid radwaste system to allow the transfer of wastes contained within either of the evaporator bottoms tanks or spent resins storage tanks through the bulk waste processing packaging equipment, or to allow wastes to be transferred directly to a bulk waste disposal station, bypassing the spent resin storage tanks.

CHEMICAL ADDITION POT - The portable skid provides the flexibility to add various chemicals to the Radwaste systems and components as needed.

11.4.2.3 System Operation 11.4.2.3.1 Solidification System Solids inputs to the solidification system, such as spent resins and charcoal, are sluiced to either the spent resin storage tank (primary) or spent resin storage tank (secondary),

or directly to a bulk waste disposal station, depending upon which component supplied the waste.

11.4-4 Rev. OL-23 6/18

CALLAWAY - SP FILTER CARTRIDGES - Where acceptable per the applicable NRC, DOT, and state regulations, filter cartridges which may be disposed of without stabilization, may be packaged in common drums with up to 12 cartridges per drum or placed within a Low Specific Activity (LSA) box. Filter cartridges requiring stabilization for disposal, will be packaged in individual 55-gallon drums or in approved High Integrity Containers.

11.4.2.3.2 Dry Waste System Low-level dry active wastes are collected at appropriate locations throughout the plant, as dictated by the volume of these wastes generated during operation or maintenance.

Dry wastes are packaged in approved containers for offsite volume reduction.

Compactors are located in the radwaste building and auxiliary building. The dry waste compactors have an integral shroud which directs any airborne dusts created by the compaction operation through an exhaust fan and filter, and then to the respective building's ventilation system. Although provided, the compactors are not normally used.

Packaged containers are sealed and moved either to the drum storage area in the radwaste building, fenced radwaste yards, or to another approved storage location, where they are stored until shipment offsite.

Packaged low-level dry active waste may be placed in cargo boxes, such as "Sealands",

approved for shipping low-level radioactive waste by the DOT, located in staging areas adjacent to the radwaste building within a RPA.

Large components and equipment which have been contaminated or activated during operation are normally handled either by qualified plant personnel or by outside contractors specializing in radioactive materials handling, and are packaged in shipping containers or appropriate shipping packages of an appropriate size. Due to their size, the original steam generators and original reactor vessel closure head are stored in the Old Steam Generator Storage Facility (OSGSF).

11.4.2.3.3 Resin Handling System The resin handling system provides the capability for remote removal of spent radioactive resin and activated charcoal from the demineralizer and charcoal adsorber vessels in the chemical and volume control system, fuel pool cooling and cleanup system, boron recycle system, liquid radwaste system, steam generator blowdown system, and secondary liquid waste system and to transfer them to the associated spent resin storage tank or bulk waste disposal station.

In the resin transfer mode, the spent resin sluice pumps take suction from the storage tank via a screened connection on the tank and pump water through the respective vessel to first backflush the resin and then sluice the resin to the spent resin storage tank. Primary resin may be also sluiced from the demineralizer vessel to the primary 11.4-5 Rev. OL-23 6/18

CALLAWAY - SP spent resin storage tank with reactor makeup water. Steam generator blowdown resin may be sluiced from the demineralizer vessel to the secondary spent resin storage tank with reactor makeup water. Primary resin or steam generator blowdown resins may also be sluiced directly to the bulk waste disposal station with reactor makeup water. Positive indication that the resin has been sluiced to the spent resin storage tank or bulk waste disposal station is provided by radiation measuring instrumentation located in the spent resin sluice header or by visually monitoring the bulk waste container.

The spent resin storage tank (primary), which accepts spent resins from waste processing systems, is capable of accommodating at least 60 days' waste generation at normal generation rates. The spent resin storage tank (secondary), which accepts spent resin and spent activated charcoal from the remaining vessels, is capable of accommodating at least 30-days' waste generation at normal generation rates.

Spent resin and spent activated charcoal are transferred from the spent resin storage tanks to the bulk waste disposal station by pressurizing the storage tank with nitrogen and supplying sluice water at the outlet nozzle on the tank for bulk waste processing.

The empty demineralizer or charcoal adsorber vessels are filled with clean media by gravity sluicing from the resin charging tank or by pumping a slurry directly from the new media container into the associated vessels. The filling operations are performed remotely from the vessels being filled.

11.4.2.3.4 Filter Handling System Filter cartridge changeouts are to be performed utilizing manual changeout techniques.

11.4.2.4 Bulk Waste Disposal Bulk waste disposal, as the name implies, involves the processing of large volumes of waste via bulk processing means for subsequent disposal.

The bulk waste disposal station consists of a set of flanged connections installed in a common crossover leg of the solid radwaste system process piping through which spent resin/spent activated charcoal from the spent resins storage tanks may be transferred.

Piping or hose connections are made between the bulk waste disposal station waste transfer flange and either a vendor processing skid or directly to an appropriate container such as a liner or a High Integrity Container (HIC). Hoses and/or piping utilized are subjected to pressure tests to verify leak-tight connections and adequacy of the hose or pipe to safely contain and transport the waste.

11.4-6 Rev. OL-23 6/18

CALLAWAY - SP Liners or HIC's provided for bulk dewatering of spent resins/spent activated charcoal incorporate dewatering internals ensure compliance with burial site criteria regarding free water within the disposal container.

Dewatering of vendor provided liners or HIC's may be performed by plant operating personnel and equipment, provided the dewatering process and methods to verify dewatering are in compliance with vendor recommendations and applicable regulatory requirements.

Upon completion of bulk processing and packaging the liner or HIC is either stored on-site in an approved storage area or shielded storage container or shipped directly offsite for processing by an intermediate processor or for disposal.

11.4.2.5 Packaging, Storage, and Shipment Spent resins, spent charcoal, spent filter cartridges, and solid compactable wastes such as paper, rags, and clothing are packaged in approved containers, in accordance with 49 CFR, and shipped in shielded casks, as required to meet 49 CFR dose limitations.

Packaged solid radwaste is normally stored in one of two locations, depending on the requirements for radiation shielding and the amounts of waste temporarily stored onsite.

These two locations are designated drummed and bulk solid radwaste storage locations.

The storage location for drummed solid radwaste is an annex to the radwaste building, on the south side, as shown in Figure 1.2-3. This storage area includes shielding cubicles for the storage of high level waste such as spent resins and filters. Other containers of radwaste may also be stored in this area. This structure (i.e., the annex to the radwaste building) has concrete walls for radiation shielding. Within this structure are two storage areas, containing 550 and 1,180 square feet of usable floor area. These areas are shielded and remotely maintained to limit radiation exposure to operating personnel. On the basis of stacking the filled drums 5 levels high, the drum capacities of the two areas are 395 and 1,055 drums, pyramidal, or 585 and 1,365 drums, palletized.

Packaged solid radwaste in drums, HICs, LSA Boxes, etc., will normally consist of:

- Spent resins, primary

- Filter cartridges, primary

- Spent resins, secondary

- Hazardous/chemical wastes

- Dry wastes 11.4-7 Rev. OL-23 6/18

CALLAWAY - SP It is estimated that the maximum total of these wastes will be 923 drums per year (refer to Table 11.4-3). Based on this estimate, there is capacity in the radwaste building for approximately 2 years of drummed solid wastes.

The storage location for bulk solid radwaste is normally in the outside area adjacent to the drummed storage annex section of the Radwaste Building, on the Plant West side of the building, extending Plant South to the Discharge Monitoring Tank area. This storage area is provided with a concrete slab surface for placement of containers, and is enclosed by a fence with access gates, for control of access to the area. Packaged solid radwaste, in HICs, Boxes or DOT approved shipping containers, is temporarily stored in this or other approved locations onsite while awaiting shipment to an off-site treatment or disposal facility, or for radioactive decay prior to long term storage within a facility structure.

While no protection from the environmental elements is afforded to the packaged radwaste containers stored in outside locations, the containers used for packaging these wastes are DOT approved containers for shipment. These containers are designed and manufactured to meet the conditions incident to shipping and disposal. On-site storage containers will be used for interim storage of high integrity containers.

Refer to Table 11.4-3 for Estimated Maximum Annual Quantities of Solid Radwaste.

11.4.3 SAFETY EVALUATION The containers that require radiation shielding are stored in the radwaste building, which is resistant to tornadoes. These drums will remain in place during any extreme environmental event. The drums or other approved shipping containers for noncompacted, dry wastes, etc., stored outside in bulk storage have low specific activities and, thus, even if dispersed by a tornado do not pose a radiation risk to onsite or off site personnel.

The drummed radwaste storage area protects the containers from rainfall and corrosion.

As described in Chapter 2.0, flooding is not a potential concern in grade-level buildings at the Callaway site.

Although wastes are expected to be stored onsite for some period of time prior to shipment, normally no credit other than 30-day decay will be taken for radioactive decay realized by such storage when filling containers for shipping in accordance with 49 CFR dose limitations. That is, once filled, containers can normally be shipped immediately, subject to availability of a disposal site, with the proper shielding, without exceeding Department of Transportation radiation limits. If 49 CFR dose limitations cannot be met with the available shielding, however, the applicable containers are stored in appropriate storage areas until the doses are acceptable for shipping in accordance with Department of Transportation requirements.

11.4-8 Rev. OL-23 6/18

CALLAWAY - SP The minimum onsite residence time for low level solid radwaste prior to shipping, such as dry compacted waste, steam generator blowdown spent resins, and spent charcoal, ranges from several days to a few months. The minimum onsite residence time for solid radwaste prior to shipping, such as primary spent resins and spent filter cartridges from the primary system, ranges from a few months to a few years. Onsite residence time is based on the initial activity of the container, the time required to have sufficient containers to completely load a transporting vehicle, the thickness of the shields available, the number of containers which can be stored in the available shipping casks, the availability of a transporting vehicle, and the availability of ultimate disposal facilities.

All solid radwaste is shipped from the site in Department of Transportation-approved containers by Department of Transportation-approved carriers. Containers with any significant surface dose rate are moved remotely from the shielded storage areas to the transporting vehicle.

Radiation measurements made at the time of shipment of any radioactive waste material ensure that all shipments leave the site well within prescribed limits. Similarly, external contamination measurements are made to detect any potential release of radioactive material from the container prior to shipment.

11.4.4 TESTS AND INSPECTIONS The SRS is in intermittent use throughout normal reactor operation. Periodic visual inspection and preventative maintenance are conducted using normal industry practice.

Refer to Chapter 14.0 for further information.

11.4.5 INSTRUMENTATION APPLICATION Two control panels are provided for the equipment in the SRS which contains or processes potentially radioactive fluids or slurries. One control panel is located in the radwaste building control room and contains the instrumentation for the equipment which interfaces the influent systems (i.e., spent resin storage tank - primary, and spent resin storage tank - secondary) and for the equipment used for process control (i.e., caustic addition tank, and caustic addition metering pump).

The second control panel (solidification control panel) is located in a separate room in close proximity to the solidification processing area. The control panel contains all instrumentation, including television monitors, required for transferring waste to the bulk waste disposal station. Pertinent instruments and controls for the transferring of the wastes from the tanks containing the wastes are duplicated on this panel so that the solid radwaste solidification system operator can transfer the waste from these tanks to the bulk waste disposal station.

CALLAWAY - SP 11.5 PROCESS AND EFFLUENT RADIOLOGICAL MONITORING AND SAMPLING SYSTEMS The function of the process and effluent radiological monitoring systems is to monitor, record, and control the release of radioactive materials that may be generated during normal operation, anticipated operational occurrences, and postulated accidents.

The process and effluent radioactivity monitoring systems furnish information to operations personnel concerning radioactivity levels in principal plant process streams and atmospheres. The monitoring systems indicate and alarm excessive radioactivity levels (GDC-63). They initiate operation of standby systems, provide inputs to the ventilation and liquid discharge isolation systems, and record the rate of release of radioactive materials to the environs, as outlined in Regulatory Guide 1.21 and GDCs 60 and 64. The systems consist of permanently installed, continuous-monitoring devices together with a program and provisions for specific sample collections and laboratory analyses.

11.5.1 DESIGN BASES The principal objectives and criteria of the process and effluent radiological monitoring systems are provided below.

11.5.1.1 Safety Design Bases SAFETY DESIGN BASES - The control room ventilation monitors, the containment purge monitors, and the fuel building exhaust monitors are designed to activate engineered safety features systems in the event that airborne radioactivity in excess of allowable limits exists. Additional design bases are stated in the following sections:

a. Containment purge isolation system, Sections 6.2.4, 7.3.2, 9.4.6, and 12.3.4.

b. Fuel building ventilation isolation, Sections 7.3.3, 9.4.2, and 12.3.4.

c. Control room intake isolation, Sections 6.4.1, 7.3.4, 9.4.1, and 12.3.4.

These radioactivity monitors are protection system elements and are designed in accordance with IEEE Standard 279.

The safety evaluation of these systems is discussed in Section 7.3.

These monitors also serve for in-plant worker protection, and this function is discussed in Section 12.3.4. Compliance with Regulatory Guide 1.97 is discussed in Appendix 7A.

11.5-1 Rev. OL-24 11/19

CALLAWAY - SP 11.5.1.2 Power Generation Design Bases POWER GENERATION DESIGN BASIS ONE - The process and effluent radioactivity monitors operate continuously during both intermittent and continuous discharges of potentially radioactive plant effluents, in compliance with Regulatory Guide 1.21. The monitors verify that the most restrictive anticipated nuclides are at concentrations within the limits specified in Table II of Appendix B of 10 CFR 20 and that the concentrations are low enough that 10 CFR 50 Appendix I dose guidelines are met for unrestricted areas.

POWER GENERATION DESIGN BASIS TWO - The process and effluent radioactivity monitors alarm and automatically terminate the release of effluents when radionuclide concentrations exceed the limits specified (GDC-60). Where termination of releases is not feasible, the monitors provide continuous indication of the magnitude of the activity released.

POWER GENERATION DESIGN BASIS THREE - The radwaste process system monitors measure radioactivity in process streams to aid personnel in the treatment of radioactive fluids prior to recycle or discharge (GDC-63).

POWER GENERATION DESIGN BASIS FOUR - The process and effluent radioactivity monitors monitor the containment atmosphere, spaces containing components for recirculation of LOCA fluids, effluent discharge paths, and for radioactivity that may be released from postulated accidents, as required by GDC-64.

POWER GENERATION DESIGN BASIS FIVE - The process and effluent monitors indicate the existence and, to the extent possible, the magnitude of reactor coolant and reactor auxiliary system leakage to the containment atmosphere, cooling water systems, or the secondary side of the steam generators.

POWER GENERATION DESIGN BASIS SIX - The process and effluent radioactivity monitors provide alarm and automatic termination of the transfer of radioactivity fluids to storage facilities in zone A areas, defined in Section 12.4.1.1.

POWER GENERATION DESIGN BASIS SEVEN - Process radioactivity monitors provide alarm and gross indication of the extent of any failed fuel within the primary system.

POWER GENERATION DESIGN BASIS EIGHT - The effluent radioactivity monitors provide sufficient radioactivity release data to prepare the reports required by Regulatory Guide 1.21.

11.5-2 Rev. OL-24 11/19

CALLAWAY - SP 11.5.1.3 Codes and Standards Codes and standards applicable to the process and effluent radioactivity monitors are indicated in Table 3.2-1. The monitors listed in Section 11.5.1.1 are designed as protection system elements.

11.5.2 SYSTEM DESCRIPTION 11.5.2.1 General Description 11.5.2.1.1 Data Collection The process and effluent radiological monitoring systems consist of liquid and airborne radioactivity monitors with the attendant controls, alarms, pumps, valves, and indicators required to meet the design bases. Each monitor consists of the detector assembly and a local microprocessor. The local microprocessor processes the detector assembly signal in digital form, computes average radioactivity levels, stores data, performs alarm or control functions, and transmits the digital signal to the control room microprocessor.

Signal transmission is accomplished via redundant data highways. A single fault in either data highway will not prevent the control room microprocessor from receiving the data. The Laundry Decon Facility Dryer Exhaust Monitor is a self contained unit and provides alarms and control function locally.

The local microprocessors for monitors which perform safety functions (control room ventilation, fuel building ventilation, containment atmosphere, and containment purge monitors, refer to Section 12.3.4) are wired directly to individual indicators located on the seismic Category I radioactivity monitoring system cabinets in the control room. The input from the safety-related channels to the daisy-chain loop is an isolated signal to ensure that the safety-related signals will not be affected by signals or conditions existing in the nonsafety portion of the system.

The control room microprocessor provides controls and indication for the radioactivity monitoring system. Indication is via a Visual Display located in the control room. The signals from each monitor may also be recorded on a system printer.

11.5.2.1.2 Alarms Each monitor channel is provided with a three-level alarm system. One alarm setpoint is below the background counting rate and serves as a circuit failure alarm. The other two-alarm setpoints provide sequential alarms on increasing radioactivity levels. Loss of power will cause an alarm on all three-alarm circuits. The alarms must be manually reset and can be reset only after the alarm condition is corrected. The Laundry Decon Facility Dryer Effluent Monitor will alarm and isolate the effluent path when measured levels are above the alarm setpoint or the monitor fails.

11.5-3 Rev. OL-24 11/19

CALLAWAY - SP 11.5.2.1.3 Check Sources Each monitor is provided with a check source, operated from the control room, which simulates a radioactive sample in the detector assembly for operational and gross calibration checks. The Laundry Decon Facility Dryer Effluent Monitor is source checked manually.

11.5.2.1.4 Power Supplies All Class 1E radioactivity monitoring systems are powered from Class 1E motor control centers. The power supplies for all of the monitors are given in Table 11.5-5.

11.5.2.1.5 Calibration and Maintenance The radioactivity monitors are calibrated by the manufacturer for at least the principal radionuclides listed in Tables 11.5-1 through 11.5-4. The manufacturer's calibration standards are traceable to National Bureau of Standards primary calibration standard sources and are accurate to at least 5 percent. The source detector geometry during this primary calibration is identical to the sample detector geometry. Secondary standards counted in reproducible geometry during the primary calibration are supplied with each continuous monitor. The secondary standards are accurate to at least 10 percent. The Laundry Decon Facility Dryer Exhaust Monitor is calibrated on site using plant procedures.

Channel checks and source checks are performed at regular intervals to ensure proper monitor function. The monitors are re-calibrated at regular intervals, and following repairs or modifications, using the secondary radionuclide standard.

Any effluent released to the environment is analyzed for radioactivity prior to release. If, at any time, an effluent monitor requires maintenance or decontamination, the effluent stream will be terminated or periodic grab sampling with laboratory analysis will be implemented in accordance with Offsite Dose Calculation Manual requirements. This does not impair system integrity since the detector is off-line and not installed in the stream.

11.5.2.1.6 Sensitivities Each effluent monitoring system will be able to detect a minimum concentration within the release limits established in the Offsite Dose Calculation Manual.

Due to sensitivity considerations, monitors are located at the effluent release points.

Dilution factors between the release point and the site boundary are considered in complying with the limitations of 10 CFR 50, Appendix I. Tables 11.5-1 through 11.5-4 provide the detailed sensitivity requirements for the process and effluent monitors.

11.5-4 Rev. OL-24 11/19

CALLAWAY - SP 11.5.2.1.7 Monitor Locations The monitors are located in low background areas, near the systems being monitored, to minimize background and sampling interferences.

11.5.2.1.8 Ranges and Setpoints The ranges of the various process monitors are based on the expected activity levels in the system being monitored. The bases for their setpoints are determined by the need for process control and to alert the operators of leakage of radioactivity into normally nonradioactive systems.

The ranges of the various effluent monitors are based on the ability to detect radioactivity concentrations at the effluent release point which might result in site boundary doses in excess of 10 CFR 50 Appendix I levels to those from postulated accidents. The Alert alarm is administratively established at a point sufficiently below the High alarm so as to provide additional assurance that Offsite Dose Calculation Manual limits are not exceeded. The High alarm is established to ensure that Offsite Dose Calculation Manual limits are not exceeded.

The ranges and setpoints for the process and effluent monitors are provided in Tables 11.5-1 through 11.5-4.

11.5.2.1.9 Expected System Parameters The expected ranges of system parameters, such as flow, composition, and concentrations, are summarized in Tables 11.5-1 through 11.5-4. Detailed information on the individual systems can be found in other sections of the FSAR, principally Chapters 9.0 and 11.0.

11.5.2.2 Liquid Monitoring Systems 11.5.2.2.1 Selection Criteria for Liquid Monitors The liquid monitors consist of fixed-volume, off-line, lead-shielded sample chambers through which the liquid samples flow. A NaI(Tl) gamma scintillation detector is located within each sample chamber to detect the activity level. Except for the Chemical and Volume Control (CVCS) Letdown Monitor, the detector assemblies monitor gross gamma activity in the range of 10-7 to 10-2 Ci/ml. The CVCS letdown monitor detector assembly monitors failed fuel product activity in the range of 1.7 x 10-3 to 1.7 x 10+3 Ci/

ml. The controlling isotope for the liquid monitors is Cs-137. Minimum detectable concentrations are listed in Tables 11.5-1 and 11.5-2.

11.5-5 Rev. OL-24 11/19

CALLAWAY - SP A motor operated valve at the sample chamber inlet is provided to isolate sample flow to permit purging of the sample chamber to facilitate background activity checks. A source of noncontaminated water is provided for decontamination purposes.

Sample chambers in which permanent contamination interferes with measurement can readily be replaced.

Liquid monitor alarms are annunciated in the control room on the plant annunciator and the radiation monitoring system Visual Dislay and printer. The radiation monitoring system Visual Display provides a visual alarm display in the control room.

The liquid radioactivity monitors are located to comply with the design bases. The specific sample points are selected to provide representative samples of the systems monitored, to reduce sample transport times, and to limit the amount of radioactivity released in the event of a high radioactivity signal.

The continuous liquid radioactivity monitoring systems are discussed in the following sections. A summary of the functions and characteristics of each monitor is presented in Tables 11.5-1 and 11.5-2.

11.5.2.2.2 Liquid Process Radioactivity Monitors A detailed listing of liquid process monitor parameters is given in Table 11.5-1.

11.5.2.2.2.1 Component Cooling Water Monitors The component cooling water system (CCWS) is discussed in Section 9.2.2.

The CCW radioactivity monitors, 0-EG-RE-9 and 0-EG-RE-10, detect, indicate, and alarm any inleakage to the CCWS from potentially radioactive systems and components served by the CCWS. Each detector assembly receives a continuous sample flow from the CCW heat exchanger inlet in the associated loop and returns the sample to the component cooling pump section header. This sample point is downstream of all potential radioactive inleakage. The component cooling pumps provide the motive force for the sample. The alert alarm provides indication of inleakage to the system. A high alarm is provided to indicate increasing radioactivity levels and to close the component cooling water surge tank air vent valves.

11.5.2.2.2.2 Steam Generator Liquid Radioactivity Monitor The steam generator liquid sample system is discussed in Section 9.3.2.

The steam generator liquid radioactivity monitor, 0-SJ-RE-2, monitors the blowdown from the steam generators, either individually or collectively, to detect, indicate, and alarm primary-to-secondary system leaks in the steam generators.

11.5-6 Rev. OL-24 11/19

CALLAWAY - SP The monitor also provides backup information and verification of the condenser air removal system gaseous radioactivity monitor (Section 11.5.2.3.2.1). The fixed-volume detector assembly receives a continuous flow from the steam generator liquid sample header which samples the tube sheet area near the minimum water level of the steam generators. The sample point is located downstream of the sample system heat exchanger to provide conditioning and pressure reduction of the radioactivity monitor sample. The radioactivity alarms provide indication of primary-to-secondary leakage in the steam generator.

11.5.2.2.2.3 Steam Generator Blowdown Processing System Radioactivity Monitor The steam generator blowdown processing system is discussed in Section 10.4.8.

The steam generator blowdown processing radioactivity monitor, 0-BM-RE-25, continuously monitors the fluid entering the steam generator blowdown filters to detect, alarm, and indicate excessive radioactivity levels in the blowdown system. The monitor provides backup information for the steam generator liquid radioactivity monitor (Section 11.5.2.2.2.2) and the condenser air removal gaseous radioactivity monitor (Section 11.5.2.3.2.1) for the detection of a primary-to-secondary leakage in the steam generator.

The fixed-volume detector assembly receives a continuous flow from the discharge of the blowdown system heat exchangers and returns the sample to the system. The sample location provides an unfiltered sample at temperatures within the limits of the detector. The high radioactivity alarm closes the blowdown system discharge valve to prevent discharge of radioactivity from the steam generators.

11.5.2.2.2.4 Essential Service Water/Service Water System Radioactivity Monitor No radioactivity monitors are required in the Service Water/Essential Service Water (SW/

ESW) System. Monitors are not required because components served by SW/ESW are normally non-radioactive. To detect inleakage into the SW/ESW system, periodic samples of the SW/ESW system will be analyzed. Analysis of SW/ESW for activity will be performed weekly when the Component Cooling Water and the Steam Generator Blowdown activity is less than the alarm setpoint of 0-EG-RE-09, 0-EG-RE-10, 0-SJ-RE-02 and 0-BM-RE-25. This sampling will be performed more frequently if radiation monitors 0-EG-RE-09, 0-EG-RE-10, 0-SJ-RE-02 or 0-BM-RE-25 reach the alarm setpoint.

11.5.2.2.2.5 Deleted 11.5.2.2.2.6 Chemical and Volume Control Letdown Monitor The chemical and volume control system (CVCS) is discussed in Section 9.3.4.

The CVCS letdown radioactivity monitor, 0-SJ-RE-01, acts as a gross failed fuel detector.

The fixed-volume detector assembly continuously monitors the CVCS letdown sample line which extracts a sample upstream of the CVCS letdown demineralizers. The 11.5-7 Rev. OL-24 11/19

CALLAWAY - SP radiation alarms alert the operator to an abnormal increase in gamma activity in the CVCS letdown system. Determination of the cause can be made by laboratory analysis.

The sample location provides an unfiltered sample prior to demineralization. The arrangement and location of the sample line provide sufficient delay in transport to allow decay of nitrogen-16, which could cause erroneously high readings.

11.5.2.2.2.7 Auxiliary Steam System Condensate Recovery Monitor The auxiliary steam system is discussed in Section 9.5.9.

The auxiliary steam condensate recovery radioactivity monitor, 0-FB-RE-50, detects radioactive contamination from the potentially radioactive systems which discharge to the auxiliary steam condensate recovery tank. The fixed-volume detector assembly continuously monitors the discharge of the auxiliary steam condensate transfer pumps.

The radioactivity alarms alert the operator to possible contamination. The source of the contamination can be determined by selective isolation of the potentially radioactive systems. The sample location ensures that all potentially radioactive sources are monitored.

11.5.2.2.3 Liquid Effluent Radioactivity Monitors A detailed listing of the liquid effluent monitor parameters is given in Table 11.5-2.

11.5.2.2.3.1 Steam Generator Blowdown Discharge Radioactivity Monitor The steam generator blowdown system is discussed in Section 10.4.8.

The steam generator blowdown discharge radioactivity monitor, 0-BM-RE-52, continuously monitors the blowdown discharge pump outlet to detect radioactivity due to system demineralizer breakthrough and to provide backup to the steam generator blowdown process radioactivity monitor (Section 11.5.2.2.2.3) to prevent discharge of radioactive fluid. The sample point is located on the discharge of the pump in order to monitor discharge or recycled blowdown fluid and upstream of the discharge isolation valve to limit the radioactivity released.

The high radioactivity alarm acts to close the blowdown isolation valves and the blowdown discharge valve.

Laboratory isotopic analyses will be performed in accordance with the Offsite Dose Calculation Manual.

11.5.2.2.3.2 Liquid Radwaste Discharge Monitor The liquid radwaste system is discussed in Section 11.2.

11.5-8 Rev. OL-24 11/19

CALLAWAY - SP The liquid radwaste radiation monitor, 0-HB-RE-18, continuously monitors the discharge of the liquid radwaste, steam generator blowdown, secondary liquid waste, and liquid waste discharged from the radwaste discharge monitor tanks to prevent the discharge of radioactive fluid to the environs. The fixed-volume detector assembly continuously monitors the system discharge line upstream of the discharge valve. The high radioactivity alarm closes the liquid radwaste system discharge valve to terminate discharge. The sample point is located to ensure that all potentially radioactive fluids from the liquid radwaste processing system are monitored prior to discharge. Laboratory isotopic analyses will be performed on each batch, prior to discharge, in accordance with the Offsite Dose Calculation Manual.

11.5.2.2.3.3 Deleted 11.5.2.2.3.4 Deleted 11.5.2.3 Airborne Monitoring Systems 11.5.2.3.1 Selection Criteria for Airborne Monitors 11.5.2.3.1.1 Introduction The type of fixed instrumentation used for monitoring airborne radioactivity is offline. The offline system extracts a sample from the process stream and transports that sample to the radioactivity monitoring system, which contains the specified equipment to detect particulates, halogens, and/or noble gases.

11.5.2.3.1.2 Sampling Criteria The sampling system for the particulate/halogen/noble gas monitors is designed and installed to meet the intent of ANSI N13.1-1969 guide to sampling of airborne radioactive materials. Systems whose sensitivity is dependent upon sample flow employ isokinetic nozzles and suitable control of flow rate.

11.5.2.3.1.3 Detection Criteria Since both radioactive particulates and radioactive noble gases are beta emitters, beta sensitive scintillation detectors are used to sense radioactivity in order to minimize the effects due to background radiation and, consequently, obtain a lower minimum detectable concentration. The Laundry Decon Facility Dryer Exhaust Monitor uses a Geiger-Mueller counter.

Where spectrometric analysis is required (such as in iodine monitoring) an NaI(Tl),

gamma scintillation detector assembly is employed.

11.5-9 Rev. OL-24 11/19

CALLAWAY - SP 11.5.2.3.1.4 Instrumentation Criteria Instrumentation necessary to indicate, alarm, and perform control functions will be provided to complete the monitoring system.

Since radioactive concentrations may vary substantially, wide range instruments are utilized. The particulate and charcoal filters can readily be removed for periodic isotopes laboratory analyses, as required by the Offsite Dose Calculation Manual.

The airborne particulate monitors each consist of a fixed filter upon which radioactive particulate matter is deposited. The fixed filter is located in front of a beta scintillation detector coupled to a photomultiplier tube. The fixed filter for the Laundry Decon Facility Dryer Exhaust Monitor is located in front of a Geiger-Mueller counter.

Each airborne iodine monitor consists of a charcoal cartridge upon which iodine is adsorbed. The air sample is prefiltered to remove particulates. The charcoal cartridge is located in front of a gamma scintillation detector coupled to a photomultiplier tube.

Each airborne noble gas monitor consists of a fixed-volume sample chamber through which prefiltered sample air is passed. A beta scintillation detector is located within the sample chamber to detect the activity level of the air sample.

All of the detectors and sample chambers are enclosed in heavily shielded lead pigs.

Two motor-operated valves operated locally are provided to permit air-purging of the sample chamber to facilitate background activity checks. The Laundry Decon Facility Dryer Exhaust Monitor detector is shielded from background. Isolation and purge valves are not installed.

The sensitivities and alarm setpoints are given in Tables 11.5-3 and 11.5-4. The alert-alarm points are based on the most restrictive isotopes which are expected to be present.

11.5.2.3.2 Airborne Process Radioactivity Monitors A detailed listing of airborne process monitor parameters is given in Table 11.5-3.

11.5.2.3.2.1 Condenser Air Discharge Monitor The condenser air discharge monitor, 0-GE-RE-92, is provided to detect, indicate, and alarm gaseous activity in the condenser air removal system exhaust. This monitor provides backup to the steam generator liquid and the steam generator blowdown processing radiation monitors for detection of primary-to-secondary leaks in the steam generator. The condenser air removal system removes noncondensable gases which would be present if a primary-to-secondary leakage occurred.

11.5-10 Rev. OL-24 11/19

CALLAWAY - SP The monitor extracts a representative sample of air and noncondensable gases from the exhaust duct. A sample cooler is provided to dry the sample prior to entering the fixed-volume gaseous detector assembly to preclude damage to the detector. The sample point is located upstream of the condenser air removal system filters.

The radiation alarms alert the operator to the presence of gaseous activity and the possibility of steam generator tube leakage.

11.5.2.3.2.2 Containment Atmosphere Radioactivity Monitors The containment atmosphere radioactivity monitors, 0-GT-RE-31 and 0-GT-RE-32, continuously monitor the containment atmosphere for particulate, iodine, and gaseous radioactivity.

These monitors also serve for reactor coolant pressure boundary leakage detection (See Section 5.2.5 for a detailed description of this function) and for personnel protection (see Section 12.3.4 for a detailed description of this function). The containment atmosphere radioactivity monitors provide backup indication for the containment purge monitors.

These seismic Category I monitors are completely redundant.

Samples are extracted from the operating deck level (El. 2047'-6") through sample lines which penetrate the containment. The monitors are located as close as possible to the containment penetrations to minimize the length of the sample tubing and the effects of sample plate out. The sample points are located in areas which ensure that representative samples are obtained. Each sample passes through the penetration, then through the fixed filter (particulate), charcoal filter (iodine), and fixed-volume gaseous detector assemblies. After passing through the pumping system, the sample is discharged back to the containment through a separate penetration.

Indication is provided for each monitor on individual indicators on the radioactivity monitoring system control panel and, through isolated signals, on the radioactivity monitoring system Visual Display in the control room.

11.5.2.3.2.3 Containment Purge System Radioactivity Monitors The containment purge system radioactivity monitors, 0-GT-RE-22 and 0-GT-RE-33, continuously monitor the containment purge exhaust duct during purge operations for particulate, iodine, and gaseous radioactivity. The purpose of these monitors is to isolate the containment purge system on high gaseous activity via the ESFAS. See Sections 7.3.2 and 9.4.6 for additional information concerning this function. These monitors also serve as backup indication for personnel protection (see Section 12.3.4) and reactor coolant pressure boundary leakage detection (see Section 5.2.5) for the containment atmosphere radioactivity monitors.

These seismic Category I monitors are completely redundant.

11.5-11 Rev. OL-24 11/19

CALLAWAY - SP The sample points are located outside the containment between the containment isolation dampers and the containment purge filter adsorber unit.

Each monitor is provided with two isokinetic nozzles to ensure that representative samples are obtained for both normal purge and minipurge flow rates. Isokinetic nozzle selection is accomplished by sample selector valves which automatically align the correct nozzle to the monitor based on operation of the minipurge and normal purge exhaust systems. The sample is extracted through the selected nozzle and then passed through the selector valve, the fixed filter (particulate), charcoal filter (iodine), and fixed-volume gaseous detectors. The sample then passes through the pumping system and is discharged back to the duct.

Indication is provided for each monitor on individual indicators on the radioactivity monitoring system control panel and, through isolated signals, on the radioactivity monitoring system Visual Display in the control room.

For plant conditions during CORE ALTERATIONS and during movement of irradiated fuel within containment, the function of the monitors is to alarm only and the trip signals for automatic actuation of CPIS may be bypassed. One instrumentation channel at a minimum is required for the alarm only function during plant refueling activities.

11.5.2.3.2.4 Containment High Range Radiation Monitors The containment high range radiation monitor (CHRRM) system includes two redundant monitors, 0-GT-RT-59 and 0-GT-RT-60, to detect and indicate gamma radiation levels in the containment as described in Table 7A-3. The CHRRM also provides an alarm function.

Each CHRRM subsystem consists of a gamma radiation detector, a microprocessor, junction box, and control/display module. The subsystems are safety related and designed and qualified to IEEE 323-1974 for the normal and accident environments for their installed locations. The subsystems are also designed and qualified to be seismic Category I. The detector locations are indicated on Figure 12.3-2, Sheet 4. Detectors are mounted on the inside surface of the containment wall at El. 2052'-0". The CHRRM subsystems are also connected to the process and effluent radiation monitoring system (optically isolated) for readout on the visual display in the control room.

11.5.2.3.2.5 Fuel Building Ventilation Exhaust Radioactivity Monitor The fuel building ventilation exhaust radiation monitors, 0-GG-RE-27 and 0-GG-RE-28, continuously monitor for particulate, iodine, and gaseous radioactivity in the fuel building ventilation exhaust system. In the event of a fuel handling accident, these monitors function to isolate the normal ventilation and start up the emergency ventilation system on high gaseous activity via the ESFAS. Sections 7.3.3 and 9.4.2 have additional information about this function. These monitors have an additional function to alert 11.5-12 Rev. OL-24 11/19

CALLAWAY - SP workers to high airborne radioactivity in the fuel building. This latter function is discussed in Section 12.3.4.

These seismic Category I monitors are completely redundant.

During normal operation, each monitor extracts a sample from the normal exhaust duct through individual isokinetic nozzles and sample selector valves. This normal sample point is upstream of the fuel building normal exhaust filter adsorber unit.

When the emergency ventilation system is in use, the capability is provided from the control room to transfer the sample points via sample selector valves to isokinetic nozzles located in the fuel building emergency exhaust system upstream of the emergency exhaust filter adsorber units, with one monitor aligned to each emergency exhaust duct.

Indication is provided by individual indicators on the radioactivity monitoring system control panel and, through isolated signals, by the radioactivity monitoring system Visual Display in the control room.

11.5.2.3.2.6 Control Room Ventilation Radioactivity Monitor The control room ventilation radioactivity monitors, 0-GK-RE-04 and 0-GK-RE-05, continuously monitor the supply air of the normal heating, ventilation, and air-conditioning system for particulate, iodine, and gaseous radioactivity to provide protection for the control room operators. These monitors function automatically to switch the control room from the normal to the emergency ventilation system on high gaseous activity via the ESFAS. See Sections 6.4, 7.3.4, and 9.4.1 for more details.

These monitors also function to alert the operators to high airborne radioactivity in the control room ventilation supply. This function is described in Section 12.3.4.

These seismic Category I monitors are completely redundant.

Samples are extracted through individual isokinetic nozzles, and flow through the fixed filter (particulate), charcoal filter (iodine), and fixed-volume gaseous detector assemblies prior to passing through the pumping system for discharge to the auxiliary building atmosphere.

Indication for these monitors is provided on individual indicators on the radioactivity monitoring system control panel and, through isolated signals, on the radioactivity monitoring system Visual Display in the control room.

11.5.2.3.3 Airborne Effluent Radioactivity Monitors A detailed listing of airborne effluent monitor parameters is given in Table 11.5-4.

11.5-13 Rev. OL-24 11/19

CALLAWAY - SP 11.5.2.3.3.1 Unit Vent Radioactivity Monitor The unit vent radioactivity monitor, 0-GT-RE-21, continuously monitors the effluent from the unit vent for particulate, iodine (halogen), and gaseous radioactivity. The unit vent, via ventilation exhaust systems, continuously purges various tanks and sumps normally containing low-level radioactive aerated liquids that can potentially generate airborne activity.

The exhaust systems which supply air to the unit vent are from the fuel building, auxiliary building, the access control area, the containment purge, and the condenser air discharge.

All of these systems are filtered before they exhaust to the unit vent. The unit vent monitor measures actual plant effluents and not inplant concentrations. Thus, the system continuously monitors downstream of the last point of potential radioactivity entry. The monitoring system consists of an off-line, three-way airborne radioactivity monitor. An isokinetic sampling probe is located downstream of the last point of potential radioactivity entry for sample collection.

The Alert alarms are set below the High alarms to act as precautionary warnings. The High alarm is set to ensure that the Offsite Dose Calculation Manual limits are not exceeded. Refer to Table 11.5-4 for the alert and high alarm setpoints, the range, and the sensitivity.

Portions of the sample tubing located outside the building are adequately protected and routed to prevent the accumulation and freezing of condensate. The sample extracted by the isokinetic nozzle is passed through the fixed filter (particulate), charcoal filter (iodine), and fixed-volume (gaseous) detector assemblies and then through the pumping system for discharge back to the unit vent.

Indication is provided on the radioactivity monitoring system Visual Display in the control room. This monitor provides a signal to the radioactive release report generation system described in Section 11.5.2.1.1.

11.5.2.3.3.2 Radwaste Building Ventilation Effluent Radioactivity Monitor The radwaste building ventilation effluent radiation monitor, 0-GH-RE-10, continuously monitors for particulate, halogen, and gaseous radioactivity in the effluent duct downstream of the exhaust filter and fans. The sample point is located downstream of the last possible point of radioactive influent, including the waste gas decay tank discharge line. The flow path provides ventilation exhaust for all parts of the building structure and components within the building and provides a discharge path for the waste gas decay tank release line. These components represent potential sources for the release of gaseous and air particulate and iodine activities in addition to the drainage sumps, tanks, and equipment purged by the waste processing system.

11.5-14 Rev. OL-24 11/19

CALLAWAY - SP The monitoring system consists of a fixed filter particulate monitor, an iodine monitor, and gaseous activity monitor.

The sample is extracted through an isokinetic nozzle to ensure that a representative sample of the air is obtained prior to release to the environment. After passing through the fixed filter (particulate), charcoal filter (halogen), and fixed-volume (noble gas) detector assemblies and the pumping system, the sample is discharged back to the exhaust duct.

The sensitivities and alarm setpoints are given in Table 11.5-4. The Alert alarm is set below the High alarm to act as a precautionary warning. The High alarm is set to ensure that Offsite Dose Calculation Manual limits are not exceeded.

Indication of this monitor is provided on the radiation monitoring system Visual Display in the control room. This monitor provides a signal to the radioactive release report generation system in the computer room (see Section 11.5.2.1.1).

This monitor will isolate the waste gas decay tank discharge line if the radioactivity release rate is above the preset limit when the waste gas discharge valve has been deliberately or inadvertently opened.

11.5.2.3.3.3 Laundry Decon Facility Dryer Exhaust Monitor The Laundry Decon Facility Dryer Exhaust Monitor, 0-GL-RE-202, continuously monitors for particulate radioactivity in the effluent duct downstream of the exhaust filter and fans.

This flow path provides ventilation exhaust for the Decon Facility Dryers.

The air in this flow path is filtered before exhausted to the environment. The Laundry Decon Facility Dryer Exhaust Monitor measures actual plant effluents and not inplant conditions. The monitoring system consists of an off-line, fixed filter particulate monitor.

The sample is extracted through an isokinetic nozzle to ensure that a representative sample of the air is obtained prior to release to the environment. After passing through the fixed filter (particulate) the sample is discharge locally.

The sensitivities and alarm setpoint is given in Table 11.5-4. The alarm is set to ensure that the Offsite Dose Calculation Manual limits are not exceeded.

The monitor will isolate the discharge path when measured levels are above the alarm setpoint or the monitor fails.

11.5.2.4 Safety Evaluation The control room ventilation monitors, the containment atmosphere monitors, the containment purge monitors, the containment LOCA atmosphere monitors, and the fuel building exhaust monitors are redundant, independent, seismic Category I, with Class 1E 11.5-15 Rev. OL-24 11/19

CALLAWAY - SP power supplies. The control room and fuel building monitors will automatically switch from the normal to the emergency ventilation systems on high gaseous activity via the ESFAS. The containment atmosphere and containment purge monitors will automatically isolate the containment purge and stop the fans on high gaseous activity via the ESFAS.

11.5.3 EFFLUENT MONITORING AND SAMPLING All potentially radioactive effluent discharge paths are continuously monitored for gross radiation level, except as described below. Liquid releases are monitored for gross gamma. Airborne releases are monitored for gross beta activity (particulates and noble gases) and gross gamma (iodines). The Laundry Decon Facility Dryer Exhaust is monitored for particulates.

Airborne batch release for the Containment ILRT post-test vent may utilize pre-test grab samples in conjunction with ODCM calculation methodology, without the need for continuous monitoring. Refer to Table 16.11-4.

Laboratory isotopic analyses are performed on continuous and batch effluent releases in accordance with the Offsite Dose Calculation Manual requirements. Results of these analyses are compiled and appropriate portions are utilized to produce the Annual Radioactive Effluent Release Report in accordance with Technical Specification 6.9.1.7.

By a combination of the installed equipment described previously in Section 11.5 and the installed equipment described in Section 12.3.4, along with portable equipment described in Section 12.5, and the emergency plan as described in Section 13.3, the requirements of General Design Criterion 64 to monitor normal operations, anticipated operational occurrences, and postulated accidents are met.

11.5.4 PROCESS MONITORING AND SAMPLING All potentially significant radioactive systems which lead to effluent discharge paths are equipped with a control system to automatically isolate the discharge on indication of a high radioactivity level. These include the containment purge system, the fuel building ventilation system, and the gaseous and liquid radwaste systems. Batch releases are sampled and analyzed in accordance with Offsite Dose Calculation Manual requirements, in addition to the continuous effluent monitoring.

By means of the continuous radioactivity monitors mentioned above and their associated control valves, and due to the extensive sampling program described in the Environmental Report, General Design Criterion 60 and the Offsite Dose Calculation Manual requirements are met with regard to the control of releases of radioactivity to the environment.

Process monitoring is accomplished by continuous radioactivity monitors discussed in Sections 11.5.2.2.2 and 11.5.2.3.2. By means of the continuous radioactivity monitors, 11.5-16 Rev. OL-24 11/19
