BACKGROUND estimate of the radioactive effluents and public dose is provided that documents projected lic dose consequences are within 10 CFR 50 Appendix I radioactive release criteria. The mates were based on nominal assumptions and generic models and based on plant operations core power level of 3636 MWt. These dose estimates were developed in support of the inal license and updated during MPS-3 restart. These dose estimates are historical and not ject to future update. This information is retained to avoid loss of original design basis.

Radiological Effluent Monitoring and Offsite Dose Calculation Manual (REMODCM) vide guidance requirements for system operation, dose calculations, and monitoring uirements, and to ensure compliance with effluent limits. Actual measured concentrations of oactivity released and real time dilution or dispersion estimates are required to verify pliance with effluent limits. Therefore, it is operation within the requirements of the MODCM that ensures compliance with effluent limits, rather than operation to the nominal mptions in this chapter.

Annual Radioactive Effluent Release Report and Annual Radiological Environmental rating Report, which are required to be submitted in May of each year, document that ration of the plant complies with effluent limits and appropriate regulations. Technical cifications requires implementation of the REMODCM and Radiation Environmental nitoring Program.

ioactive liquid and gaseous releases are described in Sections 11.2 and 11.3, respectively. All uction factors and decontamination factors associated with these systems are discussed in the ropriate sections.

.1 RADIONUCLIDE INVENTORY IN THE CORE discussion on core inventory presented below represents information used by the original nse application to establish plant shielding and radwaste effluent assessments. It is retained for orical purposes to avoid loss of original design basis and is not subject to future update. The inventory used for accident analyses is presented in Chapter 15.

specific activity of fission products in the core is calculated using the computer program TIVITY2. This program calculates the contribution from parent, daughter, and nddaughter isotopes by solving the following differential equations:

1. First order nuclides:

dN ci ( t )

---

= F i - ( i + h i + i )N ci ( t ) (11.1-1) dt

2. Second order nuclides:

Library data ude decay scheme information, production information, purification factors for typical ineralizers, and fuel escape rate coefficients. The library also contains decay gamma spectra even energy groups. Input data include time intervals, initial source inventory in the fuel, tron flux, power level, fraction of fuel defects, and density of reactor coolant. The program cribes the system analyzed, as well as the operating history, the activities, and associated ma spectral information as a function of time. Fuel assembly source terms for shielding gn, given in Chapter 12, are calculated by this method.

calculation of the core iodine fission product inventory is consistent with the inventories n in TID-14844 (DiNunno et al., 1962). The core iodine and noble gas fission product entories in Table 11.1-1 are based on continuous operation of the unit at 3,636 MWt (design output plus 2.0 percent instrumentation error). The core inventory source terms used for pter 15 radiological accident analyses have been revised to reflect requirements as described Regulatory Guide 1.183 and is discussed in Section 15.0.9.1.

core inventory information listed in Table 11.1-1 is being retained for historical purposes ause that was the basis for original plant shielding design as described in Section 12.2.1.

hese calculations, the defective fuel rods were assumed to be present in the initial core and ormly distributed throughout the core. Thus, the fission product escape rate coefficients were ed upon average fuel temperature. Calculations are performed using the average temperature he reactor coolant. The reactor coolant density correction of 1.4 was made in order to obtain correct radionuclides concentration downstream of the letdown heat exchanger.

o included in Table 11.1-2 are the expected equilibrium concentrations for the RCS. These lts were based on measured and calculated concentrations given in NUREG-0017 (USNRC

6) and the parameters listed in Table 11.1-3.

expected reactor coolant activities were used to develop the source terms for gaseous and id effluents in Sections 11.2 and 11.3.

h expected and design reactor coolant activities were used to evaluate the ventilation design in pter 12.

methodology to calculate the current design basis primary coolant activity concentrations is ilar to that used during original licensing basis with a minor modification. The design basis inventory is calculated by industry computer code ORIGEN instead of ACTIVITY2. Since source of primary coolant fission product activity is the leakage of core activity via the ctive fuels, the primary coolant activity concentrations calculated by ACTIVITY2 are sted by the ratio of the core inventory developed by ORIGEN, and presented in Chapter 15, to core inventory calculated by ACTIVITY2. The coolant concentration for a given isotope ends on the core inventory, the escape coefficients of the isotope and its precursor isotopes, the depletion rate of the isotopes. For each isotope in the primary coolant, the decay chain and escape coefficients are examined, and those isotopes that have significant impact on the centration of the referenced isotope in the coolant are identified. Amongst these major tributors, the ratios of the ORIGEN core activity to the ACTIVITY2 core activity are erally very close to each other, and the maximum scaling factor is used to adjust the TIVITY2 based coolant concentration to reflect the core developed by ORIGEN.

current design basis reactor coolant equilibrium activities presented in Table 11.1-2A, are ed on parameters listed in Table 11.1-3A.

.3.2 Tritium Activity re are two principal contributors to tritium production within the pressurized water reactor em: the ternary fission source and the dissolved boron in the reactor coolant. Additional tributions are made by Li-6, Li-7, and deuterium in the reactor water. Tritium is also produced uclear reactions with boron contained in burnable poison rods. Tritium production from erent sources is shown in Table 11.1-4.

11.1-4 Rev. 30

s tritium is formed within the fuel material and may:

1. Remain in the fuel rod uranium matrix

2. Diffuse into the cladding and become fixed there, as zirconium tritide

3. Diffuse through the cladding and be released into the primary coolant, or

4. Be released to the coolant through microscopic cracks or failures in the fuel cladding vious WNES fuel design has conservatively assumed that the ratio of fission tritium released the coolant to the total fission tritium formed was approximately 0.30 for Zircaloy clad fuel.

operating experience at the R.E. Ginna Plant of the Rochester Gas and Electric Company, and ther operating pressurized water reactors using zircaloy clad fuel, has shown that the tritium ase through the Zircaloy fuel cladding is less than the earlier estimates. Consequently, the ase fraction has been revised downward from 30 to 10 percent based on these data CAP-8253 1974).

ic Acid Source irect contribution to the reactor coolant tritium concentration is made by neutron reaction with boron in solution. The concentration of boric acid varies with core life and load follow so that is a steadily decreasing source during core life. The principal boron reactions are B-10(n,2) and B-10(n,)Li-7(n,n)H-3 reactions. The Li-7 reaction is controlled by limiting the overall um concentration to approximately 2 ppm during operation.

nable Poison Rod Source se rods are in the core only during the first operating cycle and their potential tritium tribution is only during this period.

ium and Deuterium ium and deuterium reactions contribute only minor quantities to the tritium inventory (Table

-4). These sources are due to the activation of the lithium and deuterium in the RCS as they s through the reactor. Lithium-6 is essentially excluded from the system by using 99.9 percent ign Bases design intent is to reduce the tritium sources in the RCS to a practical minimum to permit ger retention of the reactor coolant within the plant without compromising operator exposures.

uction of source terms is provided by using hafnium or Ag-In-Cd control rods instead of B4C 11.1-5 Rev. 30

ign Evaluation le 11.1-4 compares a typical design basis tritium production which has been used in the past to blish system and operational requirements of the plant and present expected values. There are principal contributors to the expected tritium release to the RCS: ternary fission source and dissolved boron in the reactor coolant.

ause of the importance of the ternary fission source on the operation of the plant, WNES has n closely following operating plant data at the R. E. Ginna Plant. The R. E. Ginna Plant has a aloy clad core with silver-indium-cadmium control rods. The operating levels of boron centration during the startup of the plant are approximately 1,100 to 1,200 ppm of boron. In ition, burnable poison rods in the core contain boron which contributes some tritium to the lant, but only during the first cycle. Data during the operation of the plant have very clearly cated that the present design sources were conservative. The tritium released is essentially m the boron dissolved in the coolant and a ternary fission source which is less than 10 percent.

ddition to these data, other operating plants with Zircaloy clad cores have also reported low um concentrations in the RCS after considerable periods of operation.

s quantity of tritium becomes uniformly distributed in the RCS, the primary grade water em, and the boron recovery system. During refueling operations, the tritium is further diluted n the refueling canal is filled from the borated refueling water storage tank.

expected tritium concentration in the primary coolant is based on the value provided in REG-0017 (USNRC 1976). For radioactive liquid waste analysis, it is assumed that 50 percent he activity produced and entering into the coolant in 1 year is released in the radioactive liquid te system effluent. The remaining 50 percent is released in the radioactive gaseous waste em and ventilation effluents.

design tritium concentration in the primary coolant is selected to allow limited access to the tainment during normal operation. The water management plan controls tritium centrations to design levels and also allows for continuous containment access during eling with operation of the containment ventilation system.

ed on the above, the following conclusions have been reached:

1. The tritium levels in plants operating with Zircaloy clad cores are lower than previous design predictions.

2. The tritium source at full power operation is reduced by using hafnium control rods.

11.1-6 Rev. 30

rosion products in the reactor coolant become activated when they pass through the core. The t important corrosion products are Cr-51, Mn-54, Fe-55, Fe-59, Co-58, and Co-60. The osion product activity is dependent on many factors, including the type of plant and the erials of construction. The mass transport process is complex and stochastic, and calculational hods to predict corrosion product activity accurately have not been successfully correlated h operational data (Bartlett 1969). Analytical predictions of the corrosion product activity ls are approximations. Therefore, design corrosion product levels are assumed to be the es measured at operating reactors. The design corrosion product levels are based on REG-0017 (USNRC 1976) values modified by the appropriate adjustment factor described ein.

corrosion product activities in the reactor coolant are given in Table 11.1-2, for the original nse and Table 11.1-2A for current conditions.

.3.4 Nitrogen-16 Activity ogen-16 is a concern only during reactor operation because of its short half-life (7.1 seconds).

ogen-16 is produced in circulating primary coolant entering the core region and irradiated by trons. Reactions with all three oxygen isotopes 0-16 (99.76 percent), 0-17 (0.037 percent), and 8 (0.204 percent) result in the production of N-16.

ogen-16 emits high energy gammas in 75-percent of the disintegrations (70-percent at 6.13 V and 5 percent at 7.11 MeV).

N-16 activity at various points in the RCS is given in Table 11.1-5.

.4 RADIOACTIVITY IN THE SECONDARY SIDE concentrations of principal radioisotopes in the secondary side of the steam generators are d for both the design and expected cases in Table 11.1-6 for liquid and Table 11.1-7 for steam.

se tables present secondary coolant and steam data used by the original license application to blish plant shielding and radwaste effluent assessments. This data is retained for historical poses to avoid loss of original design basis and is not subject to future update.The design lts for fission and activation products, based on parameters in Table 11.1-3, were calculated h the computer program IONEXCHANGER which solves the following differential equations secondary liquid activities.

occasion, the Unit will generate liquid radioactive waste that cannot practicably be processed he liquid radwaste system. The station may process this waste outside the Unit in compliance h state and federal regulations, and in accordance with the Radiological Effluent Control gram outlined in the Administrative Section of the Technical Specifications (e.g., Unit 1 porator or shipped off site for processing).

radioactivity values provided in this section are the design basis values used for the design of liquid waste system. As such, they are considered historical and not subject to future updating.

information is retained to avoid loss of the original design bases. Actual liquid radioactive ase quantities can be found in the annual radioactive effluent release reports as submitted to NRC.

.1 DESIGN BASES

1. The design objectives of the liquid waste management systems are:

a. To control the releases of radioactive materials within the limits set forth in 10 CFR 20 and to meet the numerical design objectives of Appendix I to 10 CFR 50.

b. To meet the anticipated processing requirements of the plant. Adequate storage capacity is provided to hold liquid wastes during periods when major processing equipment may be down for maintenance or during periods of excessive waste generation.

2. Table 11.2-1 gives the daily input, in terms of average and peak flows, to the waste management systems. These values are based on the values in NUREG-0017, April 1976.

3. Listings of expected and design case concentrations and annual quantities of radionuclides released to the plant discharge are given in Tables 11.2-6 and 11.2-9.

11.2-1 Rev. 30

Table 11.2-2.

5. The radioactive liquid waste (LWS) and condensate demineralizer liquid waste systems (LWC) (removed from service) are designated nonnuclear safety (NNS).

Equipment is designed and fabricated in conformance with codes and standards identified in Regulatory Guide 1.143 (Section 1.8).

6. The foundation and walls of the radioactive liquid waste building and the condensate polishing facility building are seismically designed in conformance with Regulatory Guide 1.143.

7. A cost-benefit analysis for reducing cumulative dose to the population by using available technology has been performed in accordance with Regulatory Guide 1.110 and is included in Appendix 11A.

8. General Design Criterion 61 applies with regard to provisions for suitable shielding for radiation protection of personnel under normal and postulated accident conditions. Radiation protection criteria for the radioactive liquid waste system are given in Section 12.2.

9. Releases to the environment are monitored prior to discharge. Process and effluent radiological monitoring systems are described in Section 11.5.

10. The following design features are incorporated to reduce maintenance, equipment downtime, liquid leakage, and gaseous releases to the building atmosphere, or otherwise improve radwaste operations:

a. Dished, sloped, and conical bottoms are used in vessels and tanks with a potential for high activity and suspended solids to minimize buildup of radioactive sludge and facilitate cleaning.

b. Pressure-retaining components of the system utilize welded construction to the maximum practicable extent. Flanged joints or suitable quick-disconnect fittings are used only where maintenance or operational requirements clearly indicate that such construction is preferable. Screwed connections in which threads provide the only seals are not used except for instrumentation connections where welded connections are not suitable.

Process lines are not less than 3/4-inch. Screwed connections backed up by seal welding, socket welding, or mechanical joints are used on lines greater than 3/4-inch but less than 2.5 inch nominal size. For lines of 2.5 inches and above, piping is butt-welded (except as noted by FSAR Table 1.8-1).

Backing rings are not used in lines carrying resins or other particulate material. All welding constituting the pressure boundary of pressure-retaining components is performed in accordance with ANSI B31.1.

11.2-2 Rev. 30

d. Pumps handling radioactive liquids are fitted with mechanical seals and outboard restriction bushings to minimize leakage. In the event of a seal failure, the leakage is directed to a radioactive sump through a drain connection.

e. Piping is designed and valves are selected to minimize crud pockets where activity could accumulate.

f. Tanks that are expected to contain liquids of high radioactivity are vented to the aerated vent system (Section 9.3.3) to minimize the potential for gaseous releases into working areas.

g. A centralized control panel is provided to allow system operation and monitoring from one location.

h. Components handling highly radioactive liquids are separated by shield walls to minimize exposure to operators and maintenance personnel.

i. Plastic pipes are not used for radioactive service.

11. The design provisions to control radioactive releases due to overflows from all liquid tanks containing potentially radioactive materials are shown in Table 11.2-3.

.2 SYSTEM DESCRIPTION

.2.1 Radioactive Liquid Waste System (LWS) radioactive liquid waste system consists of two separate, but interconnected, portions: The h-level waste portion and the low-level waste portion.

h-Level Waste Portion o 26,000-gallon high-level waste drain tanks accept and store high-level radioactive liquid te from the sources identified in Table 11.2-1. Tank capacity allows time for recirculating and pling of one tank while the other tank is being filled from any of the above sources. Two te evaporator feed pumps service either tank. The tanks are cross-connected to the low-level te drain tanks (described below) at the discharge of the pumps.

o filters, located downstream of each waste evaporator feed pump, are available to pre-filter h-level waste drain tank contents. These filters may be operated in parallel, in series, or assed when recirculating or processing tank contents of a high-level waste drain tank.

sequent to this flowpath, the effluent from the high-level waste drain tank is processed in one 11.2-3 Rev. 30

waste evaporator, which was designed as an alternate path for processing high level waste has n demonstrated by analysis to not be required to operate in order to meet 10 CFR 50 endix I Release Criteria.

waste evaporator is designed with an external reboiler, a large liquid disengaging space, a or-liquid separator, and a tray section. These features combine to form a system with emely high separation factors for nonvolatile nuclides. A decontamination factor of greater 104 for nonvolatile nuclides is expected.

te evaporator bottoms are allowed to concentrate until either approximately 15 percent total olved and undissolved solids by weight have concentrated or an activity level to be rmined by the characteristics of the container used to ship the evaporator bottoms offsite is umulated. Evaporator bottoms are pumped to the radioactive solid waste system (Section 11.4) the waste bottoms holding tank.

uent from the high level radioactive waste demineralizer or distillate from the waste porator is collected in the waste test tanks. Samples of the liquid are analyzed for radioactivity chemistry parameters. Depending on analysis results, the liquid is discharged to the ulating water discharge tunnel (Section 10.4.5), or is capable of being recycled to the primary de water system.

amples indicate that the distillate is unacceptable for reuse or discharge, it is either passed ugh a second waste demineralizer and resampled, or sent back to the high-level waste drain s for reprocessing. The second waste demineralizer is a mixed bed of ion exchange resins in H and OH form. The resin is replaced when analysis of influent and effluent samples indicate the decontamination factor becomes unacceptable or when the radiation level exceeds a determined limit.

expected that liquid from the waste test tanks is totally discharged. For the purpose of luating the radiological impact on the environment, one hundred percent of the input flow is med to be discharged. Assurance that waste above activity limits is not inadvertently harged to the environment is provided through sampling of the waste test tank effluent and by radiation monitor in the discharge line. This monitor provides audible and visual alarms if vity levels in the effluent exceed limits. An air-operated valve in the discharge line is actuated erminate the release.

h batch is isotopically analyzed prior to release and the total activity discharged is recorded.

mposite samples are retained in accordance with the procedures outlined in Regulatory de 1.21. Detailed administrative records of all radioactive liquid releases are maintained.

imum expected decontamination factors are shown on Figure 11.2-3.

11.2-4 Rev. 30

o 4,000-gallon low-level waste drain tanks accept and store low level radioactive liquid waste m the reactor plant aerated drains system (Section 9.3.3), as identified in Table 11.2-1. These s and their respective pumps are arranged in the same manner as the high-level waste drain s.

bine building floor and equipment drains are normally discharged directly to the environment.

en there is high radioactivity in the discharge line, flow is diverted to the low-level waste em for further processing.

tem design provides for conveying the contents of the low-level waste drain tanks to the high-l waste drain tanks if the activity level of the liquid in the low-level tanks is greater than a determined level. Normally, the low-level waste is sampled, analyzed and discharged to the ulating water discharge tunnel. If the particulate concentration is above permit discharge ls, the contents of the low-level waste drain tanks will be recirculated through filter mblies using the low-level waste drain pump(s) until the particulate concentration levels are eptable. These filters are cartridge-type filters provided to remove particulate matter from the uent. Filter elements are changed when the radioactivity level at the filter surface or the sure drop across the filter exceeds a predetermined value.

urance that high-level radioactive waste is not inadvertently discharged to the environment is vided through the analysis of low-level waste drain tank liquid samples and the radiation nitor in the discharge line.

imum expected decontamination factors are shown on Figure 11.2-3.

.2.2 Condensate Demineralizer Liquid Waste System (LWC)

LWC has been removed from service and is no longer used.

s system has been isolated from the plant via locked closed valves, where possible. The system ng remains intact, such that if any leakage occurs across the locked, closed valves, it will be tained within the existing system boundary. The system is interconnected to the Unit 2 LWC at regenerant evaporator feed tanks, regenerant evaporator feed pump suction and discharge s, and at the system discharge downstream of the regenerant demineralizer (originally gned to provide added system availability, capacity, and redundancy). These interconnections isolated also, with locked closed valves, where possible. Electrical power to the system ponents is administratively controlled by plant procedures.

LWC was originally designed and installed as an evaporator system to receive and process ntially radioactive liquid waste from the condensate demineralizer-mixed bed system ction 10.4.6). Evaporator bottoms were designed to be pumped to Unit 2 for processing.

11.2-5 Rev. 30

culation Manual (ref. REMODCM CR# 95-7).

lysis has shown that LWC is not required to be operated to meet 10 CFR 50 Appendix I ase criteria.

the purpose of evaluating the radiological impact on the environment, it is assumed that 100 ent of the regenerant chemical waste is discharged to the environment.

.2.3 Other Systems Discharging Radioactive Liquid Waste boron recovery system (Section 9.3.5) receives degasified reactor coolant letdown and tor plant gaseous drains flow, as identified on Figure 11.2-3. For the purpose of evaluating the ological impact on the environment, one hundred percent of the input flow is assumed to be harged. Provisions made to protect against inadvertent discharge are similar to those for high-l radioactive liquid waste, as the boron recovery system distillate is discharged to the liquid te system upstream of the radiation monitor in the liquid waste system. Minimum expected ontamination factors are shown on Figure 11.2-3.

ing open-cycle blowdown, the steam generator blowdown (Section 10.4.8) intermittently harges directly to the circulating water discharge tunnel as part of the secondary water mistry control program. For the purpose of evaluating the radiological impact on the ironment, the following hypothetical cases have been developed.

design base case:

• 100 percent discharge to the circulating water discharge tunnel.

• Four steam generators blow down at 1 percent maximum steaming rate (MSR) for 14 days per year during hot standby.

• One steam generator blows down intermittently at 4 percent MSR, and the remaining three steam generators blow down at 1 percent MSR for 5 minutes per week per steam generator.

expected case:

• 10 percent discharge to the circulating water discharge tunnel.

• Four steam generators each blowdown at 37,000 lb/hr for a total of 148,000 lb/hr.

actual radioactive releases will be reported annually.

11.2-6 Rev. 30

dels and assumptions contained in NUREG-0017 are used to calculate the expected oactivity concentrations in the liquid discharge. The concentration from each of the parent id waste streams following treatment are presented in Tables 11.2-4 and 11.2-7 for the ected and design conditions, respectively. Liquid releases to the environment are listed in les 11.2-5 and 11.2-6 for the expected nuclide concentrations prior and subsequent to dilution h the circulating water discharge system. A similar evaluation shown in Tables 11.2-8 and

-9 are for design nuclide concentrations prior and subsequent to dilution with the circulating er discharge system. The diluted release for the expected nuclide concentrations are further lyzed for the environmental impact as described in Appendix I of 10 CFR 50 and in endix 11A of this FSAR. Table 11.2-10 presents the design nuclide concentration releases to unrestricted area in terms of fraction of maximum permissible concentration (MPC) limits cribed in 10 CFR 20, Appendix B, Table II, Column 2. The results indicate that the sum of the tions of MPC values does not exceed the limits in 10 CFR 20.

.3.1 Radioactive Liquid Waste System Leak or Failure (Atmospheric Release) accident is defined as an unexpected and uncontrolled atmospheric release from the tulated rupture of a boron recovery tank. This tank is the highest potential atmospheric release rce term because of its large volume, the relatively high potential for activity in streams ing the tank, and its location in the yard area.

atmospheric release due to the postulated rupture of this tank is minimized by prior asification and demineralization of letdown, which removes essentially all xenon and krypton most of the iodine from the tank feed. The liquid released from the tank is held in a dike until ned or pumped, under administrative control, to the liquid radioactive waste system for her processing.

radiological consequences of a postulated radioactive liquid waste system failure resulting ospheric release is reported in Table 15.0-8 based on design release assumptions in le 11.2-11, boron recovery tank concentrations in Table 11.2-12 and the X/Q values in le 15.0-11. The resulting releases are listed in Table 11.2-13. The dose methodology is ussed in Appendix 15A.

rder to bound the Stretch Power Uprate (SPU) to 3723 MWt (including 2% calorimetric ertainty), each of the iodine and noble gas isotopes released in Table 11.2-13 were scaled ed on factors determined from the ratio of the primary activity concentrations (RCS centration from Table 15.0-10 and Design concentration from Table 11.1-2) to determine the ated doses for the SPU operating condition.

radiological consequences are consistent with the guidelines of the pre-1991 version of CFR 20, i.e., the whole body dose does not exceed 500 mRem to an individual at the nearest lusion area boundary, and is substantially below the guidelines of 10 CFR 100.

11.2-7 Rev. 30

s accident is defined as an unexpected and uncontrolled postulated rupture of the boron very tank. The boron recovery tanks are located in the yard area northeast of the containment cture (Figure 1.2-2). This area is provided with dikes to retain any liquid released from a tank ure. This analysis assumes a combined rupture of a boron recovery tank and leakage into the undwater.

cription of the analysis of this event is provided in Section 2.4.13.3.

concentration of radionuclides in Niantic Bay resulting from a liquid containing tank failure given in Table 11.2-14 based upon assumptions in Table 11.2-11.

rder to bound the Stretch Power Uprate (SPU) to 3723 MWt (including 2% calorimetric ertainty), each of the isotopes in Table 11.2-14 were scaled based on factors determined from ratio of the primary activity concentrations (RCS concentration from Table 15.0-10 and ign concentration from Table 11.1-2) to determine the updated concentrations for the SPU rating condition.

centrations in Niantic Bay are within the concentration of 10 CFR 20, Appendix B, Table II as existed prior to the 1991 revision to 10 CFR 20 (see Section 2.4.13).

s section describes the capabilities of Millstone 3 to control, collect, process, store, and ose of gaseous radioactive waste generated from normal operation and anticipated operational urrences. Section 11.5 describes the process and effluent radiation monitoring systems. The tor plant gaseous and aerated vents systems are described in Section 9.3.3. The gaseous waste agement systems include the radioactive gaseous waste system and ventilation systems.

radioactive gaseous waste system (Figure 11.3-1, Sheets 1 and 2) consists of three systems: the degasification subsystem, the process gas (hydrogenated) subsystem, and low vity process vent (aerated) subsystem.

he degasification subsystem, the fluid from the reactor coolant letdown stream (CHS), or rnately, from the reactor plant gaseous drains system (DGS), is sent to a degasifier, where condensable fission product gases are removed. The remaining liquid may be transferred to volume control tank (CHS) or to the boron recovery system (BRS). The normal flowpath is m the reactor coolant letdown to the volume control tank. The gases are forwarded to the cess gas portion of GWS.

he process gas (hydrogenated) subsystem, the noncondensable fission product gas stream is dehydrated. Then, radioactive iodine is removed and the activity of the radioactive xenon and pton is reduced. Finally, the gas is released into the process vent portion of GWS.

he low activity process vent (aerated) subsystem, aerated and hydrogenated gas streams from ous plant inputs (including the process gas portion of GWS) are collected, dehydrated, and harged to the reactor plant ventilation system (HVR) for release to the environment via the lstone stack. The gas streams are monitored for radioactivity prior to release.

separate flow path, relief effluents from the degasifier, the waste evaporator, and the boron porator are collected and discharged to the reactor plant ventilation system (HVR) for release he environment via the turbine building stack.

radioactivity values provided in this section are the design basis values used for the design of Gaseous Waste System. As such, they are considered historical and not subject to future ating. The information is retained to avoid loss of the original design bases. Actual airborne oactivity release quantities can be found in the annual radioactive effluent release reports as mitted to the NRC.

.1 DESIGN BASES

.1.1 Design Objective objective of the gaseous waste management system is to process and control the release of oactive gaseous effluents to the site environs so as to maintain the exposure to radioactive eous effluents of persons in unrestricted areas to as low a level as is reasonably achievable pendix I to 10 CFR 50, May 5, 1975). This is to be accomplished while also maintaining 11.3-1 Rev. 30

.1.2 Design Criteria design of the radioactive gaseous waste system and the ventilation systems meet the owing criteria.

1. Section 11.1 discusses the design basis source terms. Expected radioactive gaseous effluents from all sources (Table 11.3-1) have been calculated using the data shown in Table 11.3-2. These values are consistent with NUREG-0017, April 1976.

2. The systems have the capability to meet the requirements of 10 CFR 20 and the dose design objectives specified in Appendix I to 10 CFR 50, including provisions to treat gaseous radioactive wastes such that:

a. The calculated annual total quantity of all radioactive material released from Millstone 3 to the atmosphere does not result in an estimated annual external dose from gaseous effluents to any individual in unrestricted areas in excess of 5 millirems to the total body or 15 millirems to the skin.

b. The calculated annual total quantity of all radioactive iodine and radioactive material in particulate form released from Millstone 3 to the atmosphere does not result in an estimated annual dose or dose commitment from such radioactive iodine and radioactive material in particulate form for any individual in an unrestricted area from all pathways of exposure in excess of 15 mRem to any organ.

c. The concentrations of radioactive materials in gaseous effluents released to an unrestricted area do not exceed the limits in 10 CFR 20, Appendix B, Table 2, Column 1.

3. The radioactive gaseous waste system is designed to meet the anticipated processing requirements of the plant. Adequate capacity is provided to process gaseous wastes during periods when major processing equipment may be down for maintenance (single failures) and during periods of excessive waste generation.

4. The system design contains provisions to control leakage and to facilitate operation and maintenance in accordance with the guidelines of Regulatory Guide 1.143 (formerly Branch Technical Position ETSB 11-1, Rev. 1)

(Section 1.8).

5. The radioactive gaseous waste system meets General Design Criteria 60 and 64 of Appendix A to 10 CFR 50 as discussed in Sections 3.1.2.60 and 3.1.2.64.

11.3-2 Rev. 30

endix 11A shows that the systems contain all items of reasonably demonstrated technology affect a reduction in dose to the population reasonably expected to be within a 50-mile radius he plant with a favorable cost benefit.

.1.4 Equipment Design Criteria le 11.3-3 lists the radioactive gaseous waste system major equipment items. This list includes erials, rates process conditions, and number of units supplied. Equipment and piping are gned and constructed in accordance with the requirements of the applicable codes ble 11.3-4).

le 3.2-1 shows the safety classes of the various systems. Seismic category, safety class, quality rance requirements, and principal construction codes information is contained in Section 3.2.

system is designed to Safety Classification NNS.

design of the system precludes an explosive mixture from accumulating. Since the system rates above atmospheric pressure, in-leakage cannot occur. Instrumentation with automatic m functions monitors the concentrations of hydrogen and oxygen in portions of the system ing the potential for containing explosive mixtures.

radioactive gaseous waste system processes letdown from the chemical and volume control em (CHS) or reactor plant gaseous drain through the degasifier at a maximum rate of 150

. Maximum letdown from the CHS is 120 gpm and the maximum flow rate from the gaseous ns system is no more than 150 gpm.

following design features are incorporated to minimize maintenance, equipment downtime, age, and radioactive gaseous releases. These features facilitate radwaste operation, and assist aintaining occupational exposures as low as is reasonably achievable.

1. Redundant degasifier recirculation pumps prevent degasifier outage due to pump failure.

2. Components requiring servicing are placed in individual shielded cubicles to minimize personnel exposure during maintenance.

3. Leakage from pumps is piped to sumps.

4. The radioactive gaseous waste system can be operated locally from the radioactive gaseous waste and process gas treatment control panels.

servative analyses of the radioactive gaseous waste system, presented in Section 15.7, onstrate that equipment failure results in doses well within the guidelines of 10 CFR 100.

.2.2 Degasifier Subsystem of Radioactive Gaseous Waste System ctor coolant letdown, containing dissolved hydrogen and fission gases, is normally directed to degasifier from the letdown line upstream of the volume control tank in the chemical and ume control system. Alternately, liquid collected by the reactor plant gaseous drains system ction 9.3.3) may be also directed to either the degasifier or the boron recovery system.

solved gases are separated from the liquid in the degasifier.

degasifier processes reactor coolant letdown continuously except as needed to process eous (hydrogenated) drains. However, reactor coolant letdown may bypass the degasifier, if red. The degasifier design flow of 150 gpm exceeds the maximum expected throughput for liquid portion of the process gas subsystem. Separation of dissolved gases at all reactor lant letdown flow rates is thus ensured. The degasifier operates at approximately 2 psig. If the asifier is not operating, it may be placed in either the standby mode or in a shutdown dition.

11.3-5 Rev. 30

process gas (hydrogenated) portion of the radioactive gaseous waste system is designed to t gases stripped from in the reactor coolant letdown and the reactor plant gaseous drogenated) drains (Figure 11.3-1).

uent gases from the degasifier contain primarily hydrogen and water vapor. A small amount of ogen and traces of xenon, krypton, argon, carbon, and iodine are also present in the effluent es. These gases and any hydrogenated gas stream from the reactor plant gaseous vent header dehumidified (dew point 35°F) in one of the two redundant process gas refrigerant dryers.

densation effluent from the dryers is returned to the suction of the degasifier recirculation

p. The dry stream is passed through and filtered by the ambient temperature process gas rcoal bed adsorbers and one of two redundant HEPA filters. The heat due to radioactive decay mall and does not affect the adsorption of noble gases on the charcoal. The charcoal bed orbers are designed to provide holdup of most krypton and xenon isotopes long enough in parison with their half-lives so that passage through the beds will result in the effective oval of these isotopes. In addition, decontamination of iodine to negligible levels is obtained ng passage through the charcoal beds. The charcoal is divided evenly between two vertical s in series. The tanks are piped so that either one may be bypassed, if necessary, with a esponding decrease in decay time; however, bypass is not anticipated. The only radioisotope ent in any quantity in the predominantly hydrogen stream after the decay period is pton-85. This processed hydrogenated stream is monitored by the supplementary leak ection monitor and released to the environment through the Millstone stack in accordance h technical specifications. The normal flow path for the processed stream is to the Millstone

k. When a test of the gas at the vent dampers at the discharge of the process vent fans is uired, then the process gas flow is monitored and released through the reactor plant ventilation t.

uid seals are provided in the drain lines from the process gas precoolers and the process gas er traps to prevent backflow of vapor from the degasifier. The process gas precooler drains tinuously at approximately 3 pounds per hour of water at 120°F. The process gas water trap ns at approximately 0.3 pound per hour at 35°F. In the event of a sudden vacuum condition at suction of the degasifier recirculation pump, the seals are temporarily lost. However, the cess gas precooler drain seal refills in approximately 10 minutes and the process gas water trap refills in approximately 100 minutes.

rocess gas monitor is provided for the gaseous releases from the process gas portion to nitor radioactivity release to the environment and to automatically isolate the flow from the cess gas receiver when a predetermined level is exceeded (Section 11.5).

Table 11.3-1 gives the expected radioactive gaseous isotope releases from h release point assumed in terms of curies per year per nuclide. Table 11.3-11 provides the gn releases for these release points.

le 11.3-2 lists the parameters in these calculations.

ummary of the estimated expected annual radioactivity doses is presented in Appendix 11A. A mary of design release concentrations at the site boundary, maximum permissible centration (MPC) and Fraction of MPCs is presented in Tables 11.3-8, 11.3-9 and 11.3-10.

design releases are within the limits of 10 CFR 20. The doses from expected releases are hin the numerical design objectives of Appendix I of 10 CFR 50. Atmospheric diffusion and und deposition factors used in the dose calculations are discussed in Section 2.3.5.

eous effluents are discharged to the environment through the following release points:

1. The reactor plant ventilation vent

2. The turbine building roof exhausters

3. The Millstone stack

4. The engineered safety features building exhaust

5. The steam generator blowdown flash tank vent

6. The turbine gland seal steam condenser exhaust on the condensate polishing building roof ease points are identified on Figure 11.3-2.

austs from the auxiliary building, the fuel building, the waste disposal building, the tainment purge, the service building, and the gaseous waste process vent are released from the tor plant ventilation vent. This vent is located on the turbine building 133 feet above grade 157 feet-0 inches above sea level. The base elevation is 75 feet above grade. The square vent s-sectional dimensions are 10 feet by 10 feet and the discharge velocity is 3,000 feet per ute. The maximum discharge temperature is 104°F. Containment purge is considered an rmittent release. Others are assumed as continuous.

turbine building ventilation system exhausts through the turbine building roof exhausters, ted on the turbine building roof. The exhausters are approximately 114 feet above grade, feet above sea level, and have a base elevation of 107 feet above grade. The system exhausts ugh roof-mounted, mushroom-type hoods with dimensions of 14 feet-6 inches by 11.3-10 Rev. 30

ing the open cycle blowdown, the steam generator blowdown flash tank is vented directly to atmosphere through a vent on the turbine building roof. The vent is a 10-inch diameter pipe ched to a roof-mounted silencer. The discharge elevation is approximately 113 feet above sea

l. Exhaust flow velocity is 8,450 feet per minute.

turbine gland sealing system exhaust is vented to the atmosphere at a point above the densate polishing building. The vent is a 10-inch diameter pipe at an elevation of 72 feet ve sea level.

reactor plant aerated vents, the reactor plant gaseous vents, condenser air removal effluent, oactive gaseous waste system discharges, steam generator blowdown tank condenser vent, containment vacuum pump discharge are released through the Millstone stack. The Millstone k is 375 feet above grade, 389 feet above sea level, and has a circular orifice with a 7 foot de diameter. The stack discharges at a maximum velocity of 332 feet per minute for accident dition and 40 feet per minute for normal condition (MP2 & MP3) at a maximum temperature 04°F. These discharges are assumed as continuous releases. The portion of the discharge vent ween the ESF building and the stack is underground.

engineered safety features building ventilation system exhausts through the ESF building t located on the east wall. The vent is 12 feet-9 inches above grade, 36 feet-9 inches above sea

l. The vent cross sectional dimensions are 3 feet-0 inches by 10 feet-0 inches and the harge velocity is 350 feet per minute. The maximum discharge temperature is 104°F. The ase from the ESF building is considered continuous and is included as part of the continuous ase from the auxiliary building in Table 11.3-5.

.3.1 Radioactive Gaseous Waste System Failure aseous waste system failure is postulated to produce a unique unplanned release by a pathway normally used for planned releases and requiring a reasonable time to detect and take remedial on to terminate the release. An inadvertent bypass of the process gas charcoal bed adsorbers h continued normal operation of the gaseous waste system for one hour is assumed. This rce is then assumed to be continually released to the auxiliary building and then directly to the ironment without holdup.

gaseous waste system design, described in Section 11.3, precludes the single failure of an ve component from causing this event, but it is postulated as the design basis accident as cribed by Branch Technical Position ETSB 11-5. For this event to occur the two manual ass valves must fail or be improperly aligned, and the piping system downstream of the orbers must experience a passive failure to result in a release directly into the auxiliary ding.

11.3-11 Rev. 30

rnal pressure is approximately 1 psig, a gross rupture of the tanks is not considered credible.

iation monitors are provided for the ventilation system in order to detect the release of noble es to the environs from the building ventilation system.

wever, no credit is taken for normal operating plant systems, instrumentation or controls, nor ration of any engineered safety feature systems to mitigate the consequences of this event.

mally, all noncondensable gases are removed from the reactor coolant letdown stream in the asifier. For this analysis it is assumed that the activity released following the bypass of process charcoal bed adsorbers consists of noble gas activities discharged from the degasifier for 60 utes and released without benefit of delay in charcoal beds. It is also assumed that a fraction of noble gases adsorbed in the charcoal beds is released. The fractions released were calculated g the model developed for the Fast Flux Test Facility (Underhill). Table 11.3-13 lists the owing:

aximum radioisotope inventory in the process gas charcoal bed adsorbers and associated ng.

raction of the charcoal bed radioisotope inventory released.

ixty-minute discharge from the degasifier.

otal radioisotope release.

le 11.3-12 gives the assumptions used for analyzing the postulated bypass of the process gas rcoal bed adsorbers.

radiological consequences of bypassing the charcoal bed adsorbers are listed in Table 15.0-8 ed on design release assumptions in Table 11.3-12, the releases in Table 11.3-13 and the X/Q es in Table 15.0-11. The dose methodology of Appendix 15A is used here.

rder to bound the Stretch Power Uprate (SPU) to 3723 MWt (including 2% calorimetric ertainty), each of the noble gas isotopes released in Table 11.3-13 were scaled based on factors rmined from the ratio of the primary activity concentrations (RCS concentration from Table

-10 and Design concentration from Table 11.1-2) to determine the updated doses for the SPU rating condition.

s event will not cause a Condition IV event as defined in Section 15.0.1. The radiological sequences are well within the guidelines of 10 CFR 100.

radioactive solid waste system is designed to collect, hold, process, dewater or solidify, kage, handle, and temporarily store radioactive materials prior to their shipment offsite and mate disposal.

radioactivity values provided in this section are the design basis values used for the design of Solid Waste System. As such, they are considered historical and not subject to future updating.

information is retained to avoid loss of the original design bases. Volumes and radioactivity tent, including specific nuclide percentages of actual shipments can be found in the annual oactive effluent release reports as submitted to the NRC.

.1 DESIGN BASES radioactive solid waste system is designed in accordance with the following criteria.

1. The system design parameters are based on radionuclide concentrations and volumes consistent with reactor operating experience for similar designs and with the source terms of Section 11.1.

2. All wet solid wastes including bulk liquids, sludges, or spent resin are dewatered, solidified or otherwise treated (as required). Procedures are used to ensure the absence of free liquid in the containers and control other appropriate waste form characteristics. The plant is compatible with any mobile processing equipment.

Plant procedures are used to ensure that mobile equipment meets federal and state disposal regulations. Dewatering equipment is portable and described in FSAR Section 11.4.2.2 and Figure 11.4-1 (2 of 2).

Processing equipment is sized to handle the design inputs without the need to ship bulk liquids. In-plant waste storage facilities provide sufficient temporary storage capacity to allow time for shipping delays. Tanks accumulating spent resins have the capability of accommodating at least 60 days waste generation at normal generation rates. Temporary storage capacity exceeds 30 days waste generation at expected generation rates. Longer term temporary storage is described in FSAR Section 11.4.2.5.

3. Solid waste containers, shipping casks, and methods of packaging meet applicable federal regulations, e.g., 10 CFR Part 71, and wastes are to be shipped to a licensed burial site in accordance with applicable NRC, e.g., 10 CFR Part 61, and Department of Transportation regulations, e.g., 49 CFR 171-178. Solid waste treatment design is in compliance with the relevant requirements of 10 CFR Part 20, sections 105 and 106 (version prior to January 1, 1994) as it relates to radioactivity in effluents to unrestricted areas.

11.4-1 Rev. 30

11-3.

5. The permanent plant system contains provisions to reduce leakage and facilitate operations and maintenance in accordance with the provisions of Regulatory Guide 1.143 and Branch Technical Position, ETSB 11-3 (July 1981).

6. The filling of containers, the dewatering, the solidification, and/or the storage of radioactive solid wastes conforms to 10 CFR 20 and 10 CFR 50 requirements and Regulatory Guide 8.8 guidelines in terms of as low as is reasonably achievable (ALARA) doses to plant personnel and the general public.

7. The temporary waste storage facilities in the waste storage building are shielded to provide protection of operating personnel in accordance with the radiation protection design considerations in Section 12.1.

8. Radiation protection personnel conducting surveys use portable radiation detectors to determine radiation levels outside and inside shielded areas. These surveys are performed to ensure that area guidelines are met and to ensure adequate personnel protection through area posting and access limitations.

9. This system is not safety-related and is classified as nonnuclear safety (NNS).

10. The portion of the solid waste buildings foundation and adjacent walls up to a height sufficient to contain the liquid inventory in the building is designed to the seismic criteria used for Millstone 3 and to the quality assurance criteria of Section 6 of Regulatory Guide 1.143.

11. Portions of the system that handle radioactive liquid waste meet the applicable design bases of Section 11.2.1.

12. The system is designed to process, handle, and store the waste types, and quantities described in Section 11.4.2 below, which are generated as a result of normal operation.

13. The system is able to reduce the volume of selected input streams to minimize packaged quantities for transport and disposal.

.2 SYSTEM DESCRIPTION radioactive solid waste system is shown on Figure 11.4-1.

layout of the solid waste building, including packaging, storage, and shipping areas, is shown igure 3.8-74.

.2.1 System Inputs erials handled as solid wastes may include any of the following: concentrated waste solutions m the waste evaporator, concentrated boric acid discarded from the boron evaporator in the on recovery system (Section 9.3.5), spent resin from radioactive process demineralizers and hangers, spent filter cartridges, and miscellaneous sludges.

ure 11.4-2 is a flow chart of the expected quantities and activity levels of the radioactive solid te generated by the plant. Gross activities and weights or volumes for radioactive solid waste rces are also given on Figure 11.4-2. Figure 11.4-3 provides the design volumes and activity ls of radioactive solid wastes and waste sources.

.2.1.1 Spent Resins ure 11.4-2 provides the estimated volumes of spent demineralizer and ion exchanger resins per

r. These resins come from a variety of different services, and the total volume estimated is ed on the individual resin bed volumes and the expected frequency of replacement (Table

-1).

.2.1.2 Waste Evaporator Bottoms porator bottoms from the waste evaporator in the radioactive liquid waste system may be sferred to the solid waste system. The estimated volume of bottoms solution to be shipped off is given on Figure 11.4-2. The calculated activity of these bottoms, also shown on Figure

.2.2 Equipment Description radioactive solid waste system equipment is operated on a batch basis. Individual ponents are designed to support the systems rated capacity.

permanently installed system consists of a control panel, spent resin dewatering and hold s, and the piping, pumps, and process equipment modules required for transfer of wastes to a ping container. The solid waste equipment requires a minimum manual action and, in junction with the building layout, is designed to minimize occupational radiation exposures.

portable portion of the system is designed to permit filling and dewatering of the resin slurry he shipping container. This portion consists of a fill/dewatering head, a dewatering pump, a trol panel, and other process equipment for drying the resin to suitable levels for shipment off pping containers are approved for the process for which they are to be used.

en slurries are being processed, the fill head is lifted by the overhead bridge crane and lowered o the shipping container having the integral dewatering line. Connected to the fill head is a te fill line, vent line, decontamination lines, and a dewatering line that extends from the fill

d. These lines are flexible, with flanged fittings to facilitate periodic replacement or ntenance. When the fill head is lowered onto the shipping container, it is aligned with the rnal dewatering line and secured prior to filling.

ic acid concentrated in the boron evaporator in the boron recovery system is typically cled. However, the capability exists to transfer waste concentrated from the waste evaporator he radioactive liquid waste system to the solid waste system.

ins sluiced from demineralizers and ion exchangers are stored in the spent resin hold tank. The ns are then slurried to the shipping container, where they are allowed to settle. Excess water is oved by the spent resin dewatering pump within the portable dewatering unit and transferred he spent resin dewatering tank.

.2.2.1 Boron, Waste Evaporator Bottoms centrated liquids from the evaporators may be pumped to the waste bottoms tank for holdup l they are to be solidified. The tank is insulated, heat traced, and is recirculated to prevent tallization, stratification, settling, and accumulation of undissolved solids.

amount of waste liquid allowed per container is determined by prior analysis of the waste.

pments are made in accordance with NRC regulations 10 CFR 20, 10 CFR 50, and 10 CFR and Department of Transportation regulations 49 CFR 171 through 178. The shipping tainers are stored temporarily in the solidification area (Section 11.4.2.5) or an interim on-site age facility prior to off-site disposal.

.2.2.2 Spent Resin Handling in in a demineralizer or ion exchanger is considered spent when the decontamination factor s below a predetermined value, when the demineralizer or ion exchanger surface dose roaches a predetermined limit, or when the resin bed pressure drop becomes excessive. The ineralizer or ion exchanger is then isolated. Water from the spent resin dewatering tank is d to flush the spent resin into the spent resin hold tank utilizing the spent resin transfer pump.

flush water passes out of the spent resin hold tank, through a screened element to prevent any n carryover, and is recirculated. When the resin is to be packaged for disposal, it is pumped as sin-water slurry to the shipping container in the processing area. Excess water is dewatered m the shipping container, via the portable dewatering unit, and returned to the spent resin atering tank. Radiation levels are monitored to ensure that DOT shipping limits are not eeded. After dewatering, the container is sealed, labeled, and temporarily stored until shipped site. Prior to shipment the container is shielded as necessary.

.1 DESIGN BASES process, effluent, and airborne radiation monitoring system (RMS) is designed in accordance h NRC General Design Criterion (GDC) 64 (Section 3.1.2.64) and American National ndards Institute (ANSI) N13.1-1969.

mal and potential paths for release of radioactive materials, during both normal operation and cipated operational occurrences, are continuously monitored to ensure compliance with the uirements of 10 CFR 20, 10 CFR 50, and the guidelines of Regulatory Guide 1.21 ction 1.8). Sections 11.5.2 and 11.5.3 describe the design features provided to ensure ement with Regulatory Guide 1.21. Potential pathways for release of radioactive materials ng accident conditions are continuously monitored to ensure agreement with the guidelines of ulatory Guide 1.97 (Sections 1.8, 7.5).

tinuous monitoring means that the system operates essentially uninterrupted for extended ods during normal plant operation, but does not preclude periods when individual monitors be out of service for maintenance, repair, calibration, etc.

reactor coolant system (RCS) is monitored continuously for gross activity level. Maintaining RCS activity within acceptable levels ensures that the activity levels in the normally oactive auxiliary systems are at acceptable levels. Nonradioactive systems which may become taminated by leaks from radioactive systems are also monitored continuously. This monitoring ures that no conditions develop that are potentially hazardous to the operating personnel or to general public.

he event of an accident releasing radionuclides, the process, effluent, and airborne RMS and area RMS (Section 12.3.4), provide information on the concentration and dispersion of oactivity throughout the plant. This enables operating personnel to evaluate the severity and to gate the consequences of the accident.

following automatic actions are initiated by the process and effluent RMS to mitigate both the sequences of postulated accidents and excessive releases during normal operations.

1. Containment purge (Section 9.4.7) is automatically terminated in the event of a high radiation alarm.

2. Liquid effluent discharges from the turbine building drains are diverted to the radioactive liquid waste systems in the event of a high radionuclide concentration alarm (Section 11.2).

3. Waste gas holdup system effluent release is terminated automatically upon a high radionuclide concentration alarm (Section 11.3.3).

11.5-1 Rev. 30

5. Control building ventilation intake is terminated on high radiation alarm, and the entire control building ventilation system is isolated (Section 9.4.1).

6. Discharge from the condensate regenerant demineralizer (removed from service) to the environment was designed to be diverted to the regenerant evaporator feed tank (removed from service) upon a high radionuclide concentration alarm (Section 11.5.2.3.8).

7. Following a high radionuclide concentration alarm from the auxiliary condensate monitor, effluent from the auxiliary condensate flash tank is diverted from the auxiliary condensate feed tank to the auxiliary building sump.

8. A high radionuclide concentration alarm from either hydrogen recombiner ventilation monitor automatically shuts down ventilation from its cubicle (Section 9.4.11).

9. Waste neutralization sump effluent discharge to the circulating water discharge tunnel is redirected back to the waste neutralization sump on a high radionuclide concentration alarm (Section 10.4.6.5).

10. Steam generator blowdown is automatically terminated on high radionuclide concentration alarm on the steam generator blowdown monitor.

.2 SYSTEM DESCRIPTION

.2.1 Instrumentation process, effluent, and airborne RMS consists of separate and independent monitors, which rporate the following features:

1. Each liquid monitor has one detector. Each particulate and gas monitor has one gaseous detector and either a fixed paper disc filter for specific radionuclide laboratory analysis, or a moving filter assembly with an internal particulate detector for gross activity measurement.

2. Each monitor is equipped with a dedicated microprocessor monitoring all its functions. The RMS computer system polls each microprocessor every few seconds. Radiation alarms are displayed and annunciated in the main control room.

Many monitors also have local alarms in addition to the control room.

3. For specified monitors, a record of radiological events is printed.

11.5-2 Rev. 30

applicable guidelines are those in Appendix B of 10 CFR 20.

dedicated microprocessor sends an alarm message to the RMS computer system in the event ocal power loss, loss of sample flow, filter failure, or other conditions specific to a given nitor.

ans are provided to purge each fixed volume sample chamber in the system with clean fluid to imize contamination of the chambers. Sample lines and all surfaces of each sampler exposed he sample are stainless steel and are run to minimize fixed contamination.

rability of many detectors can be checked using an installed check source remotely activated m the control room. Tests and calibrations of the radiation monitors are performed at specified rvals. For ease in calibration and maintenance, each detector is located in an easily accessible and is provided with a local readout device or connects to a plug-in portable indication and trol (PIC) module.

monitors and microprocessors are powered by 120 V AC buses. Monitor skids designed in ordance with Regulatory Guide 1.97 and safety-related monitors, such as the control building t and ventilation monitors, use the safety-related Class 1E buses (Section 8.3.1.1.2). All other nitors use regular 120 V AC buses (Section 8.3.1.1.1).

itionally, all monitors with pumps require 480 V AC power. Safety-related monitors with ps use safety-related Class 1E buses, and all others use regular 480 V AC buses.

6 and Fission Product Main Steam Line Monitor alarms are processed by the plant process puter. All other alarms are displayed visually on the RMS workstations in the control room.

se include equipment malfunctions, alarm/high radiation levels, conductivity, sample flow, sample temperature. Local and control room annunciation is provided for high radiation ms, as well as an interface to the main plant annunciator panel. All alarms can be nowledged locally or in the control room.

itionally, those variables designated Class 1E are also displayed on the Class 1E control room els, as required by Regulatory Guide 1.97. A digital display and control module is provided each Class 1E monitor, as well as a dedicated two-pen recorder. In order to record this data at RMS computer along with that from the non-Class 1E devices, these cabinets are connected to RMS computer via electronic isolators.

h detector has sufficient shielding to ensure that the required sensitivity is achieved for the imum expected background radiation level at the detector location.

monitors measure gross concentrations. The output is typically measured in microcuries per ic centimeter (Ci/cc), with a minimum range of five decades.

.2.2 Process and Effluent Monitors

.2.2.1 Ventilation Vent MonitorsNormal Range h skid has its own microprocessor. The two microprocessors are linked by a dedicated rface. When the normal range skid senses the upper level of its range, control is automatically sed to the high range skid. When the radionuclide concentration returns to normal, the reverse pens. Both skids use the same isokinetic nozzle. During high range operation, the normal ge gas sampler is automatically isolated.

sample line and all surfaces of the sampler exposed to the sample are stainless steel. A sample p provides isokinetic sample flow via a flow control valve which modulates proportional to flow signal from the process flow transmitter. Isokinetic sample flow is maintained through normal range skid even after the detectors are isolated during high range operation.

ventilation vent normal range monitor takes a continuous effluent sample from an isokinetic zle common to this normal and high range monitor and draws the gas sample through a iculate and charcoal filter and then to a gas sampling assembly where activity is measured by ta scintillation detector. Lead shielding is provided to reduce the background radiation to a l that minimizes interference with the detector sensitivity.

er leaving the gas sampler, the sample is returned to the duct downstream of the sample point.

urge system for flushing the sample volume is also provided.

ventilation vent normal range monitor detector output is transmitted via the dedicated roprocessor to the RMS computer system Class 1E panels located in the control room. Here, activity level is displayed and also recorded on a two-pen strip chart recorder. Activity levels also digitally displayed locally at the microprocessor location. Alarm conditions, such as high vity or monitor failure, are indicated by audible and visible alarms in the control room and by ble alarm locally.

.2.2.2 Ventilation Vent Monitor-High Range vent sample point is common to that of the ventilation vent normal range monitor and is ted downstream of the last point where radioactivity is introduced to the flow stream prior to elease via the ventilation vent stack. Sample flow through the high range monitor is ntained constant via a set hand control valve. Isokinetic flow through this monitor depends on tinued operation of the normal range monitor pump to maintain isokinetic flow conditions 11.5-4 Rev. 30

nitored by a Geiger-Mueller detector. An alarm will automatically direct flow to another filter mbly at a level which still allows analysis of the filter in a laboratory GeLi detector. An quate amount of lead shielding around the detector assembly reduces the background radiation level that minimizes interference with the detector sensitivity. After passing through the filter er, the sample passes through an inline easily removable charcoal filter cartridge arrangement then into a fixed and shielded volume where it is monitored by mid-range and high range nitors.

.2.2.3 Hydrogenated Vent Monitor hydrogenated vent monitor continuously monitors the effluent from the gaseous waste system nstream of the charcoal decay beds and prior to their release via the ventilation vent stack.

gas detector, a beta scintillator, is located in the well of an inline gas sampler. Four pi lead lding is provided in order to reduce the background radiation to a level that minimizes rference with the detector sensitivity.

s monitors output is transmitted, indicated, recorded, and alarmed in a manner similar to that ll non-Class 1E process monitors. When high activity is present, gas flow to the ventilation t stack is isolated. The sample line and all surfaces of the sampler exposed to the sample line stainless steel. Due to the presence of free hydrogen in this effluent, this monitor is purged h nitrogen.

.2.2.4 Containment Fuel Drop Monitors gross radionuclide concentration entering the containment purge air vent is monitored by two undant containment fuel drop monitors. These monitors, each consist of an ion chamber ctor measuring dose rates just above the surface of the refueling canal. These are safety-ted, Class 1E, monitors. Due to high radiation levels inside the containment, their roprocessors are located in the auxiliary building.

outputs of these monitors are transmitted, indicated, recorded, and alarmed in a manner ilar to that of the ventilation vent monitor. A high activity indication from either of these nitors automatically isolates containment purge (Section 9.4.7.2) based on the assumption that high dose rates are due to high airborne activity.

.2.2.5 Supplementary Leak Collection and Release System Monitor supplementary leak collection and release system (SLCRS) normal range and high range nitors are identical to the ventilation vent monitors. Using an isokinetic nozzle, the monitor hdraws a sample from the SLCRS exhaust vent prior to its discharge to the Millstone stack.

SLCRS collects, filters, and releases the leakage from the containment enclosure building contiguous areas to the atmosphere following a design basis accident (DBA) (Section 6.2.3).

ing normal operation, this detector monitors the discharge point for the containment vacuum 11.5-5 Rev. 30

rs and prior to the exhaust discharge point. The SLCRS monitor functions as a final effluent nitor.

s monitors output is transmitted, indicated, recorded, and alarmed in a manner similar to that he ventilation vent monitors. An alarm from this monitor warns the operator of a potential blem so that he may take appropriate action, which may include the manual transfer of flow to andby SLCRS filter bank.

.2.2.6 Condenser Air Ejector Monitor condenser air ejector monitor continuously analyzes the gaseous effluents from the condenser ejector discharge (Section 10.4.2). A gamma scintillation detector is inserted into an in-line air

l. The detector is shielded with lead to reduce the background radiation to a level which imizes interference with the detector sensitivity.

monitors output is transmitted, indicated, recorded, and alarmed in a manner similar to that he hydrogenated vent monitor. Activity readings are indicative of primary-to-secondary age.

.2.2.7 Control Building Inlet Ventilation Monitors two control building inlet monitors are located in the upper level of the control building in the t plenum. Here, they continuously analyze the ventilation being supplied to the control ding by measuring gross activity. Each monitor consists of a beta scintillation detector. These Class 1E, safety-related monitors.

detector outputs are transmitted, indicated, and alarmed in a manner similar to that of the tilation vent monitor. A high activity condition initiates a control building isolation signal ch will isolate the control building atmosphere from the outside atmosphere (Section 6.4).

.2.2.8 Hydrogen Recombiner Ventilation Monitors owing a loss-of-coolant accident (LOCA), the hydrogen recombiners were originally installed e used to eliminate the free hydrogen in the containment atmosphere. However, the tainment atmosphere following a LOCA also contains large amounts of gaseous onuclides. Should a leak develop in a recombiner, these radionuclides are collected and harged to the atmosphere via the hydrogen recombiner ventilation system (Section 9.4.11).

refore, one safety-related, post-accident, beta scintillation radiation detector is placed within exhaust duct of each ventilation system, and its dedicated microprocessor is located in the rogen recombiner control room. Upon a high radiation alarm, a signal from the monitor matically shuts down the respective hydrogen recombiner package system and activates ure of the supply and exhaust duct dampers securing the ventilation. Recombiner operators then manually start the other recombiner unit.

11.5-6 Rev. 30

.2.2.9 Normal Range Particulate and Gas Monitors ddition to the ventilation vent and SLCRS monitors, the RMS also contains 11 normal range iculate and gas monitors. They are of a single, basic skid design. The particulate channels loy either a remotely controlled, variable speed moving paper filter with an integral beta ctor, or a fixed paper disc filter for specific radionuclide analysis. The gas channel is a beta ctor. Each monitor includes a removable charcoal filter. These monitors are as follows.

1. Reactor Plant Heating and Ventilation System (Section 9.4.3)

Eight of these monitors are located in the reactor plant heating and ventilation system upstream of the ventilation vent monitor such that any effluent sampled by any one of them is also sampled by the ventilation vent monitor before it is released. These monitors allow operating personnel to locate the source of radionuclide leakage into the air of the relevant spaces. The areas sampled are in auxiliary building, the fuel building, and the waste disposal building.

These monitors are all designated non-safety related, and their outputs are indicated, recorded, and annunciated similarly to that of the condenser air ejector monitor.

2. The Engineered Safety Features Building Heating and Ventilation System (Section 9.4.5)

The engineered safety features (ESF) building heating and ventilation system normally discharges directly into the atmosphere. This monitor samples this effluent before release and employs the fixed paper filter disc design for a radionuclide analysis in compliance with Regulatory Guide 1.21. This monitor is also designated non-safety related, and its output is indicated, recorded, and annunciated similarly to that of the condenser air ejector monitor. Following an accident, this system is secured and the ESF building is ventilated by the SLCRS system, which has its own extended range radiation monitor (Section 11.5.2.2.5).

3. The Control Building Heating and Ventilation System (Section 9.4.1)

Since there are no radionuclide sources within the control building, this system is not a release point. However, this monitor provides an indication of radionuclide concentration within the control building. It provides greater sensitivity for detecting airborne activity in the control room than the control building inlet monitors.

This monitor is also designated non-safety related, and its output is indicated, recorded, and annunciated similarly to that of the condenser air ejector monitor.

11.5-7 Rev. 30

This monitor continually withdraws a sample of the containment atmosphere, analyzes it, and returns it to the containment, using dedicated sample lines. These lines are heat traced to prevent condensation and slope backwards toward the containment structure. This prevents the sample lines from becoming sources of radiation. The sample lines contain valves to isolate this monitor upon a containment isolation signal. The removable charcoal filter is not used, Iodine samples are collected using a temporary sampler.

.2.2.10 Main Steam Relief Line Monitors se four ion chamber monitors, located in the main steam valve building, measure the gross onuclide concentration in the main steam lines in the event of a steam generator tube failure.

This is an ion chamber gross detector used to meet the intent egulatory Guide 1.97, Rev. 2. Lead shielding is provided to reduce the background radiation level which does not interfere with the detector sensitivity.

turbine driven auxiliary feedwater pump discharge monitors output is transmitted via its icated microprocessor to the RMS workstations located in the control room where the activity igitally displayed. A high activity level is indicated by audible and visible alarms in the main trol room.

.2.2.12 Main Steam Line Monitor; N-16 and Fission Product monitor has four unshielded gamma scintillation detectors, one mounted on each main steam at the containment penetration in the main steam valve building. Each detector has two nnels, one to measure high energy N-16 activity and one to measure lower energy fission duct activity. This monitor inputs all eight channels and an equipment failure signal to the t process computer. The plant process computer records, displays, and provides main control rd annunciation for this monitor. This monitoring system is Non-QA, designed to support lstones Primary-to-Secondary leak rate program.

.2.3.1 Containment Recirculation Cooler Service Water Outlet Monitors ing the recirculation phase of emergency core cooling, the containment recirculation cooler ice water outlet monitors continuously measure the radionuclide concentration in the service er effluent from each pair of containment recirculation coolers (one monitor per pair of lers). These are Class 1E, on-line, gamma scintillation, gross detectors, placed atop the harge pipes just outside the ESF building. As the pipes are underground, only the detectors are mounted, with their dedicated microprocessors located in the fuel building.

activity level is also digitally displayed locally at the microprocessor location. A high activity l is indicated by audible and visible alarms locally and in the main control room. These nitors warn of a leak into the service water system, within the containment recirculation lers.

.2.3.2 Liquid Waste Monitor liquid waste monitor continuously analyzes the liquid waste effluent discharge pipe ction 11.2) downstream of the last possible point of radioactive liquid addition. The detector mbly consists of a gamma scintillation detector inserted into the well of a four-pi, lead lded liquid sampler. All surfaces in contact with the liquid sample are of stainless steel. Lead lding is provided in order to reduce the background radiation to a level which does not rfere with the detector sensitivity.

detector output is transmitted, indicated, recorded, and alarmed in a manner similar to that of condenser air ejector monitor. A high activity situation initiates closure of a discharge valve, eby preventing the discharge of effluent to the environment in excess of dose limits. The high vity alarm and isolation function are based on a time averaged activity to verify consistently h levels.

dose evaluation presented in this Appendix was developed in support of the original license portions were updated during the MPS-3 restart. These dose estimates are considered orical and not subject to future updating. This information is retained to avoid loss of original gn basis.

stated in Section 11.0, the Radiological Effluent Monitoring and Offsite Dose Calculation nual (REMODCM) provides guidance requirements for system operation, dose calculations, monitoring requirements to ensure MPS-3 compliance with effluent limits. Actual measured centrations of radioactivity released and real time dilution and dispersion estimates are zed to verify compliance with effluent limits. Therefore, MPS-3 operation within the uirements of the REMODCM ensures compliance within effluent limits, rather than operations hin the nominal assumptions utilized in the dose evaluation presented in this Chapter.

calculated annual radiation doses to the maximum individual from liquid and gaseous ways are presented in Tables 11A-1 through 11A-8 and 11A-13 through 11A-15.

le 11A-16 demonstrates that the calculated annual radiation doses are below the design ctives of 10 CFR 50, Appendix I.

maximum calculated organ dose per reactor for an individual from gaseous releases ticulates and radioiodines) is 4.4 mRem/yr to an infants thyroid. This represents a othetical infant living at the residence 2.4 km north-northeast of the site consuming milk from at at the same location.

calculated external exposure to the whole body and skin from immersion in noble gases is E-02 and 6.9E-02 mRem/yr, respectively. These represent the maximum values which occur at site boundary in the direction of the maximum overland /Q, 650 meters east-northeast of lstone 3. The maximum calculated beta and gamma air doses from noble gas releases are E-02 and 8.6E-02 mrad/yr, respectively. These were also calculated 650 meters east-northeast Millstone 3.

liquid releases, the maximum individual was assumed to consume aquatic foods whose cipal habitat is the edge of the initial mixing zone (EIMZ). This location was also servatively used in calculating doses from boating. Doses from swimming and shoreline eation were calculated at the nearest residents beach, located 1.1 km from the point of harge. The maximum calculated whole body dose for an individual from liquid pathways is E-02 mRem/yr in the adult age group. The maximum calculated organ dose for an individual m liquid pathways is 4.4E-01 mRem/yr to an adults GI-UI and 1.8E-01 mRem/yr to a childs oid. These doses were primary due to consumption of aquatic foods.

calculated annual gaseous and liquid doses from the population residing within an 80 km us of the site are presented in Table 11A-17. For liquid effluents, the calculated population e commitment within 80 km for whole body and thyroid are 1.7E+00 and 1.6E+01 man-Rem/

espectively.

es to Biota Other Than Man culation of dose rates to biota other than man was performed by means of the computer grams ARRRG and CRITER (Soldat et al., 1974), developed at the Pacific Northwest oratory of Battelle Memorial Institute under contract to the Atomic Energy Commission C). Bioaccumulation factors used in ARRRG and CRITER have been updated to correspond he latest published values in Regulatory Guide 1.109, Revision 0 (plants) and Regulatory de 1.109, Revision 1 (all others). Site specific data used in this analysis are presented in Table

following sections provide a summary of the dose models used in the analysis for each way considered.

11A.2-8 Rev. 30

atic organisms were considered to receive an internal dose rate from uptake and concentration adiochemicals in the water and from exposure through the food chain. Dose rates to primary anisms were calculated directly from radioisotopic concentrations in discharge water and from ccumulation factors. The dose rate through the food chain was estimated for secondary anisms such as muskrats and raccoons feeding on primary organisms whose radionuclide tent was estimated in the first calculation.

s appendix presents the results of cost-benefit analyses performed in accordance with Section D of 10 CFR 50, Appendix I.

ments to the liquid and gaseous effluent systems and respective potential reductions to the ual population exposure are taken from the U.S. NRC Regulatory Guide 1.110, Cost-Benefit lysis for Radwaste Systems for Light-Water-Cooled Nuclear Power Reactors (Regulatory de 1.110, 1976). The beneficial savings of each augment were calculated by multiplying the ulated dose reduction by $1,000 per man-Rem or $1,000 per man-thyroid-Rem. The cost of owed money was conservatively assumed to be 10 percent. The equations and site specific required for the dose calculations are presented in Part I of this appendix.

ments to the Liquid Effluent Treatment System le 11A.3-1 presents the calculated base case annual total body dose (man-Rem) and thyroid e (man-thyroid-Rem) associated with the operation of the plant liquid radwaste system for the ulation expected to live within an 80-km radius of the plant for the year 2010. Assuming that h augment is capable of reducing the population doses to zero (an extremely conservative mption), the maximum benefit to be derived from any augment would be $1,700 for reducing

-Rem exposures to zero and $16,000 for reducing man-thyroid-Rem exposure to zero.

n analysis of the annualized procurement, installation, operation, and maintenance costs, the t expensive liquid radwaste augment was found to be $19,000 per year for a plant located in northeastern United States. Since the benefit from this augment would be less than the esponding total annualized cost, the cost-benefit ratio is greater than 1. The operation of itional equipment for the purpose of reducing the annual population dose would not be cost ctive. Therefore, the most cost-beneficial system has been included in the current plant gn.

ments to the Gaseous Effluent Treatment System le 11A.3-2 presents the calculated base case annual total body man-Rem and thyroid

-Rem associated with the operation of the gaseous radwaste system for the 80-km radius ulation.

uming that each augment is capable of reducing the population doses to zero, the maximum efit to be derived from any augment would be $4,800 for reducing man-Rem exposures to zero

$7,800 for reducing man-thyroid-Rem exposures to zero.

n analysis of the annualized procurement, installation, operation, and maintenance costs, the t expensive gaseous radwaste augment was found to be $8,700 per year for a plant located in northeastern United States. Since the benefit from this augment would be less than the esponding total annualized cost, the cost-benefit ratio is greater than 1. The operation of itional equipment for the purpose of reducing the annual population dose would not be cost 11A.3-1 Rev. 30
