EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT (2001)

Summary of Changes to the Annual Effluent Report

1) The formatting of the supplemental information section has been revised to be more consistent with the recommendations of Regulatory Guide 1.21, while maintaining some site specific procedurally required information.
2) While there were no liquid radwaste discharges conducted, or occurrences of positive nuclide activity detected in the plant's ultimate outfall during 2001, the reporting of liquid effluents has been changed to reflect actual plant configuration. Since the plant has a common radwaste treatment facility and does not segregate inputs into radwaste by unit, and since there is a common release point from the plant's cooling pond to the Illinois River, it is appropriate for any liquid releases to be reported under Unit 1. This practice is consistent with that for reporting gaseous releases via the common vent stack. The past practice of applying half of the total liquid release activity to each unit and reporting releases under Unit 1 and Unit 2 will no longer be followed based on the reasons stated above and the fact that there is no value added from this practice.
3) In the Solid waste and Irradiated Fuel Shipments Section, "Container Type" has been changed to "Shipment Type" based on technical accuracy. While this information is not specified in Regulatory Guide 1.21, LaSalle Station's ODCM and local procedure for preparation of the Annual Effluent Report currently require it.

EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT (2001)

APPENDIX A OFFSITE DOSE CALCULATION MANUAL

Synopsis of ODCM Changes The proposed ODCM changes are being made as a result of the implementation of Improved Technical Specifications. Please find below a synopsis of those changes.

NOTE For an explanation of the specific changes to the ODCM, see attached document.

1. Many reference changes to reflect new ITS section numbers.
2. The definition of various terms is being changed to reflect ITS definitions.
3. The surveillance frequency of various instrumentation is being changed from 18 months to 24 months to reflect 24 month fuel.
4. The reporting date of the Annual Radiological Environmental Operating Report changes from May 1 to May 15.
5. Many clarifications to existing requirements.
6. Many editorial changes.
7. The most significant change to the ODCM involves a change in Chemistry sampling requirements after a change in power levels. Previously, sampling was required after a 15% power change. The proposed change requires sampling after a 20% change in power.

==

Description:==

Reference changes.

Reason: Reflect new ITS reference numbers / descriptions.

Section: 12.1.2

==

Description:==

Definition of "Channel Calibration" is changing. The "Channel Calibration" is now required to encompass the required sensor and display. Also, the following sentence is being added: Calibration of instrument channels with resistance temperature detector (RTD) or thermocouple sensors may consist of an in-place qualitative assessment of sensor behavior and normal calibration of the remaining adiustable devices in the channel.

Reason: The definition is changing to include the definition from TSTF 205 to apply to the ODCM as well as the Improved Technical Specifications. See ITS page 1.1-1.

Section: 12.1.3

Description:

Definition of "Channel Check" is changing. It is now defined to be the following: A CHANNEL CHECK shall be the qualitative assessment, by observation, of channel behavior during operation by epeFatain. This determination shall include, where possible, comparison of the channel indication and /-GF status with to other indications aA4 or status derived from independent instrument channels measuring the same parameter.

Reason: Clarification. See ITS page 1.1-1.

Section: 12.1.4 to be

Description:

Definition of "Channel Functional Test" is changing. It is now defined the following: A CHANNEL FUNCTIONAL TEST shall be the injection of a simulated signal into the channel as close to the sensor as practical to verify OPERABILITY including required alarm and4 or, interlock, display, and trip functions, and channel failure trips. The following is being deleted. Biddable hanneos the injectioG Of a fuiRGfieRs.

Reason: To be consistent with ITS definition of Channel Functional Test (See ITS page 1.1-2).

Section: 12.1.5

==

Description:==

Add reference to definition of Dose Equivalent 1-131.

Reason: Clarification.

Section: 12.1.6

==

Description:==

The definition of "Frequency" is changing. It is now defined to be the following: -Table 12.1-1 provides the definitions of various frequencies for which surveillances, sampling, etc. are performed unless defined otherwise. The-25%

' 'rac

-. hall not be applied to Operability Action statements. The bases, to Technical Specification 4.0.2 provide clarificatien*to thi require.ment. The provisions of Technical Specification SR 3.0.2 and SR 3.0.3 are applicable to the frequencies except that they do not apply to the frequencies associated with the Radiological Environmental Monitoring Program (Section 12.5).

Reason: To be consistent with ITS definition of Frequency.

Section: 12.1.9

Description:

Add definition of "Mode." It is defined to the following: A MODE shall correspond to any one of the inclusive combination of mode switch position, average temperature, and reactor pressure vessel head closure bolt tensioning specified in Table 12.1-2 with fuel in the reactor vessel.

Reason: To be consistent with Table 1.1-1 of ITS.

Section: 12.1.11

Description:

The definition of "Operable" is changing. It is now defined to be the following: A system, subsystem, trai, division, component, or device shall be OPERABLE or have OPERABILITY when it is capable of performing its specified function(s), and when all necessary attendant instrumentation, controls, normal or emergency electrical power, cooling and eG seal water, lubrication, Gr-and other auxiliary equipment that are required for the system, subsystem, #ain division, component or device to perform its function(s) are also capable of performing their related support function(s).

Reason: To be consistent with ITS definition of Operable. (See ITS page 1.1-5).

Section: Table 12.1-1

Description:

Revise frequency notation to define a refueling cycle to be 24 months.

Reason: The refueling cycle will be 24 months with the implementation of ITS.

Section: Table 12.1-1

Description:

Add notation "Sesquiannually" to mean at lease once per 18 months.

Reason: New notation needed with the use of 24-month fuel.

Section: Table 12.1-1

LASALLE Revision 3 May 2001 CHAPTER 10 RADIOACTIVE EFFLUENT TREA TMENT AND MONITORING 10.1 AIRBORNE RELEASES 10.1.1 System Description A simplified gaseous radwaste and gaseous effluent flow diagram are provided in Figure 10-1.

The airborne release point for radioactive effluents is the ventilation stack which is classified as a stack in accordance with the definitions in Section 4.1.4 and the results in Table A-1 of Appendix A.

In addition, the standby gas treatment system effluent is released through a separate stack inside the ventilation stack. This release point has the same location and classification as the ventilation stack.

Exfiltration to the environment from the Turbine Building has been identified at times of positive pressure in the Turbine Building. Within 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> of the turbine building being at positive pressure continuous air sampling shall be in place in the south Turbine Building trackway to monitor releases through this pathway. The releases through the trackway door and other potential release paths contain insignificant levels of contamination when compared to the Station Vent Stack which has a 1,000,000 cfm typical stack flow compared to the Trackway flow rate of 40,000 scfm and conservatively estimated as a total of 80,000 scfm to account for pathways other than the trackway. In addition, typical releases from LaSalle Station have not exceeded 0.02% of the 10CFR50 Appendix I dose limits. Any identified release via this pathway is a ground level release and should be considered in dose calculations. See Figure 10-1 for further information.

Waste oil burning to fuel a heat recovery system is planned to begin in the Fall of 1998.

Sampling and analyses of each batch of oil is required to be performed in accordance with ODCM Table 12.4.1-1. The effluent will be verified to be within the instantaneous release limits prior to each batch (assuming 100% of the activity in the waste oil is released in the gaseous effluent). The oil burning unit is located in an onsite building within the protected area. The effluent is released out the top of the building, is a ground level release, and will be quantified and considered in dose calculations.

Airborne releases to the environment may result if a fire occurs in a contaminated material warehouse. In the event of a fire in a contaminated material warehouse this pathway would be considered a ground level release and should be quantified and considered in dose calculations.

10.1.1.1 Condenser Offgas Treatment System The condenser offgas treatment system is designed and installed to reduce radioactive gaseous effluents by collecting non- condensable off-gases from the condenser and providing for holdup to reduce the total radioactivity by radiodecay prior to release to the environment. The daughter products are retained by charcoal and HEPA filters. The system is described in Section 11.3.2.1 of the LaSalle UFSAR.

P:\procupgd\approved\odcm\lslOr3.doc 10-1

LASALLE Revision 3 May 2001 10.1.1.2 Ventilation Exhaust Treatment System Ventilation exhaust treatment systems are designed and installed to reduce gaseous radioiodine or radioactive material in particulate form in selected effluent streams by passing ventilation or vent exhaust gases through charcoal adsorbers and/or HEPA filters prior to release to the environment. Such a system is not considered to have any effect on noble gas effluents. The ventilation exhaust treatment systems are shown in Figure 10-1.

Engineered safety features atmospheric cleanup systems are not considered to be ventilation exhaust treatment system components.

10.1.2 Radiation Monitors 10.1.2.1 Station Vent Stack Effluent Monitor Monitor OPLD5J (Wide Range Noble Gas Monitor) continuously monitors the final effluent from the station vent stack.

The monitor system has isokinetic sampling, gaseous grab sampling, iodine and particulate sampling, tritium sampling, and postaccident sampling capability.

In normal operation the low-range noble gas channel is on line and active. The mid-range channel replaces the low-range channel at a concentration of 0.01 jtCVcc png* and the high range channel replaces the mid-range channel at a concentration of 10 RUCi/cc png.

The low-range and mid/high-range iodine and particulate samplers operate in a similar manner. In normal operation the low-range samplers are on line. At a concentration of 0.001 ttCi/cc png the mid/high-range samplers are brought on line, and at a concentration of 0.1 g.CVcc png the low-range sample pump is turned off.

No automatic isolation or control functions are performed by this monitor. Pertinent information on this monitor is provided in the LaSalle UFSAR Section 11.5.2.2.1.

10.1.2.2 Standby Gas Treatment System Effluent Monitor Monitor OPLD2J (Wide Range Noble Gas Monitor) continuously monitors the final effluent from the standby gas treatment system (SGTS) stack.

The SGTS stack monitor has isokinetic sampling, gaseous grab sampling, particulate and iodine sampling, and post accident sampling capability.

In normal operation the low range noble gas channel is on line and active. The mid-range channel replaces the low-range channel at a concentration of 0.01 lxCi/cc png and the high range channel replaces the mid-range channel at a concentration of 10 IACi/cc png.

  • To facilitate use of the wide range gas monitors on the Station Vent Stack and Standby Gas Treatment System Stack in post-accident dose assessment, the output of each is expressed in units of pseudo noble gas (png) activity. Pseudo noble gas is a fictitious radionuclide defined to have emission characteristics representative of a post-accident noble gas mix. Upon decay, a pseudo noble gas nuclide emits one gamma ray with energy 0.8 MeV and one beta particle with endpoint energy 1.68 MeV and average energy 0.56 MeV.

P:\procupgd\approved\odcm\ls 10r3.doc 10-2

LASALLE Revision 3 May 2001 The low-range and mid/high-range iodine and particulate samples operate in a similar manner. In normal operation, the low-range samples are on-line. At a concentration of 0.001 jxCi/cc png the mid/high-range samplers are brought on-line, and at a concentration of 0.1 p.Ci/cc png the low-range sample pump is turned off.

No automatic isolation or control functions are performed by this monitor.

Pertinent information on this monitor is provided in the LaSalle UFSAR Section 11.5.2.2.2.

10.1.2.3 Reactor Building Ventilation Monitors Monitors 1 (2)D1 8-NOO9 continuously monitor the effluent from the Unit 1(2) reactor building. On high alarm, the monitors automatically initiate the following actions:

A. Shutdown and isolation of the reactor building vent system B. Startup of the standby gas treatment system C. Isolation of primary containment purge and vent lines Pertinent information on these monitors is provided in LaSalle UFSAR Section 11.5.2.1.1.

10.1.2.4 Condenser Air Ejector Monitors Monitors 1(2)D18-N002/N012 (pre-treatment) and 1(2)D18-N903A/B (post-treatment) continuously monitor gross gamma activity downstream of the steam jet air ejector and prior to release to the main stack.

On "high-high-high" alarm monitor 1 (2)D18-N903NB automatically initiates closure of valve 1(2)N62-F057 thus terminating the release.

Pertinent information on these monitors is found in LaSalle UFSAR Sections 11.5.2.1.2 and 11.5.2.1.3.

10.1.2.5 Turbine Building Trackway In order to quantify any identified releases via the Turbine Building trackway, at times of positive pressure in the Turbine Building, airborne sampling should be continuously collected using an air sampler located within the trackway. The air sampler collecting shall begin within 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> of the turbine building being at positive pressure, and then continuously for as long as the turbine building remains at positive pressure. The samples collected should be counted on a weekly basis. Air sampling to identify noble gas, iodine and particulate monitoring (either as a grab sample or continuous sampling) is designed to ensure evaluation of releases emanating from the Turbine Building.

The curie content of any contaminated material warehouse is maintained current by site administrative procedures. If a fire were to occur, the actual curie content of the warehouse would be used in determining the ground level release.

LASALLE Revision 3 May 2001 10.1.3 Alarm and Trip Setpoints 10.1.3.1 Setpoint Calculations 10.1.3.1.1 Reactor Building Vent Effluent Monitor The setpoint for the reactor building vent effluent monitor is established at 10 mR/hr.

10.1.3.1.2 Condenser Air Ejector Monitors Pre-Treatment Monitor The high trip setpoint is established at 1.5 times the nominal nitrogen-1 6 (N-1 6) background dose rate to help ensure that effluents are maintained ALARA.

The high-high trip setpoint is established at < 100 pCi/sec per MW-th _ 3.4E+05 giCi/sec per Technical Specification 3.11.2.2.

Post-Treatment Monitor The off-gas isolation setpoint is conservatively set at or below one-half the release limit calculated using the more conservative value obtained from equations 10-3 and 10-4 below.

The off gas isolation setpoint is converted into the monitor units of counts per second (cps) as follows:

10.1.3.1.3 Station Vent Stack Effluent Monitor The high alarm setpoint for the station vent stack effluent monitor is conservatively set at or below one-half the calculated release limit calculated using the more conservative value obtained from equations 10-3 and 10-4 below. These equations yield the release limit in P\procupgd\approved\odcm\s110r3.doc 10-4

LASALLE Revision 3 May 2001 units of jCi/sec of the mix specified in Section 10.1.3.3. For consistency with the monitor readout, this calculated release limit is converted to units of .tCi/sec of pseudo noble gas before being entered into the monitor data base.

10.1.3.1.4 Standby Gas Treatment Stack Monitor The high alarm setpoint for the standby gas treatment system effluent monitor is conservatively set at or below one-half the release limit calculated using the more conservative value obtained from equations 10-3 and 10-4 below. These equations yield the release limit in units of gCVsec of the mix specified in Section 10.1.3.3. For consistency with the monitor readout, this calculated release limit is converted to units of gCVsec of pseudo noble gas before being entered into the monitor data base.

10.1.3.2 Release Limits Alarm and trip setpoints of gaseous effluent monitors are established to ensure that the release rate limits of RETS are not exceeded. The release limit Qt. is found by solving Equations 10-3 and 10-4.

The summations are over noble gas radionuclides i.

fi Fractional Radionuclide Composition:

The release rate of noble gas radionuclide i divided by the total release rate of all noble gas radionuclides.

Qts Total Allowed Release Rate, Stack [p.CVsec of ODCM mix]

Release The total allowed release rate of all noble gas radionuclides released as stack releases in units of RCi/sec of the mix specified in section 10.1.3.3.

t exp (-XiR/3600 U.) is conservatively set equal to 1.0 for purposes of determining setpoints.

The remaining parameters in Equation 10-3 have the same definitions as in Equation A-8 of Appendix A. The remaining parameters in Equation 10-4 have the same definition as in Equation A-9 of Appendix A.

Equation 10-3 is based on Equation A-8 of Appendix A and the RETS restriction on whole body dose rate (500 mrem/yr) due to noble gases released in gaseous effluents (see Section A.1.3.1 of Appendix A). Equation 10-4 is based on Equation A-9 of Appendix A and the RETS restriction on skin dose rate (3000 mrem/yr) due to noble gases released in gaseous effluents (see Section A.1.3.2 of Appendix A).

The more conservative solution from Equations 10-3 and 10-4 is used as the limiting noble gas release rate.

Calibration methods and surveillance frequency for the monitors will be conducted as specified in the RETS.

P:\procupgd\approved\odcm\lslOr3.doc 10-5

LASALLE Revision 3 May 2001 10.1.3.3 Release Mixture In the determination of alarm and trip set points, the radioactivity mixture in the exhaust air is assumed to have the radionuclide composition in Table 10-1.

10.1.3.4 Conversion Factors The conversion factors used to establish gaseous effluent monitor setpoints are obtained as follows.

Station vent stack effluent monitor.

Calibrations compare the response of station detectors to that of a reference detector using NIST traceable sources. Conversion factors for the station detectors are obtained from the response to noble gas or solid sources.

Condenser air ejector monitor.

Pretreatment Monitor The value is determined using noble gas radionuclides identified in a representative sample, and the offgas release rate and monitor response at the time the sample is taken.

Post-treatment Monitor The value is determined using noble gas radionuclides identified in a representative sample, and the offgas concentration and monitor response at the time the sample is taken.

Standby gas treatment system monitor.

Calibrations compare the response of station detectors to that of a reference detector using NIST traceable sources. Conversion factors for the station detectors are obtained from the response to noble gas or solid sources.

10.1.3.5 HVAC Flow Rates The main stack flow rate is obtained from either the process computer or Monitor RM-23.

The SGTS flow rate is obtained from either the process computer or chart recorders in the main control room.

10.1.4 Allocation of Effluents from Common Release Points Radioactive gaseous effluents released from the main chimney are comprised of contributions from both units. Under normal operating conditions, it is difficult to allocate the radioactivity between units due to fuel performance, in-plant leakage, power history, and other variables.

Consequently, no allocation is normally made between the units. Instead, the entire release is treated as a single source.

10.1.5 Dose Projections Because the gaseous releases are continuous, the doses are routinely calculated in accordance with the RETS.

The liquid radwaste treatment system is designed and installed to reduce radioactive liquid effluents by collecting the liquids, providing for retention or holdup, and providing for treatment by filter, demineralizer, or evaporator for the purpose of reducing the total radioactivity prior to release to the environment. The system is described in Section 11.2.2 of the LaSalle UFSAR.

10.2.1.1 Radwaste Discharge Tanks There are two discharge tanks (1(2)WFO5T, 25,000 gallons each) which receive water for discharge to the Illinois River via the cooling lake blowdown.

10.2.1.2 Cooling Pond Blowdown Cooling Pond Blowdown is the liquid discharge line to the Illinois River. The Cooling Pond Blowdown has a flow monitoring device as well as a compositor to meet the sampling requirements of ODCM Table 12.3.1-2.

10.2.2 Radiation Monitors 10.2.2.1 Liquid Radwaste Effluent Monitor Monitor OD18-K907 monitors all releases from the release tanks. On hi-hi alarm the monitor automatically initiates closure of valves OWL067 and trips the radwaste discharge pump to terminate the release.

Pertinent information on the monitor and associated control devices is provided in LaSalle UFSAR Section 11.5.2.3.3.

10.2.2.2 Service Water Effluent Monitors Monitors 1/(2)D18-K912 continuously monitor the service water effluent. On high alarm service water discharge may be terminated manually. No control device is initiated by these monitors.

Pertinent information on these monitors is provided in LaSalle UFSAR 11.5.2.3.2.

10.2.2.3 RHR Heat Exchanger Cooling Water Effluent Monitors

. . Instrument channels 1/(2)D18-N906/8 continuously monitor the RHR heat exchanger coooling water effluent. On high alarm the operating loop may be terminated manually and the redundant loop brought on line. No control device is initiated by these monitors.

Pertinent information on these monitors is provided in LaSalle UFSAR Section 11.5.2.3.4.

10.2.3 Alarm and Trip Setpoints 10.2.3.1 Setpoint Calculations Alarm and trip setpoints of liquid effluent monitors at the principal release points are established to ensure that the limits of RETS are not exceeded in the unrestricted area.

LASALLE Revision 3 May 2001 10.2.3.2 Discharge Flow Rates 10.2.3.2.1 Release Tank Discharge Flow Rate Prior to each batch release, a grab sample is obtained.

The results of the analysis of the sample determine the discharge rate of each batch as follows:

Fr. = 0.1 x [Fd/II (Q/1OxDWq)] (10-6)

The summation is over radionuclides i.

0.1 Reduction factor for conservatism.

LASALLE Revision 3 May 2001 10.2.3.3 Release Limits Release limits are determined from RETS. Calculated maximum permissible discharge rates are divided by 10 for conservatism and to ensure that release concentrations are well below applicable derived water concentrations (DWC).

10.2.3.4 Release Mixture For the liquid radwaste effluent monitor the release mixture used for the setpoint determination is the radionuclide mix identified in the grab sample isotopic analysis plus four additional radionuclides. The additional radionuclides are H-3, Fe-59, Sr-89, and Sr-90. The quantities to be added are obtained from the most current analysis for these four radionuclides.

For all other liquid effluent monitors no release mixture is used because the setpoint is established at "two times background."

10.2.3.5 Conversion Factors The readout for the liquid radwaste effluent monitor is in CPM. The calibration constant is based on the detector sensitivity to Cs-137/Ba-137 and an energy response curve.

10.2.3.6 Liquid Dilution Flow Rates A conservative maximum blowdown flowrate of 20,000 gpm is used for all radwaste discharge calculations unless actual blowdown flow is determined to be less.

10.2.4 Allocation of Effluents from Common Release Points Liquid releases from the Station will be allocated one half to Unit 1 and one half to Unit 2.

Other potential pathways (i.e., RHR) are allocated to their respective unit.

10.2.5 Projected Doses for Releases Doses are not calculated prior to release. Dose contributions from liquid effluents are determined in accordance with the RETS and station procedures.

10.3 SOLIDIFICATION OF WASTE/PROCESS CONTROL PROGRAM The process control program (PCP) contains the sampling, analysis, and formulation determination by which solidification of radioactive wastes from liquid systems is ensured.

Figure 10-4 is a simplified diagram of solid radwaste processing.
