2001 Annual Radioactive Effluent Releases Report for TMI 5928-02-20095 Summary of Unplanned Releases from the TMI Site During 2001 There were no unplanned releases to unrestricted areas from either the TMI-1 or TMI-2 site during 2001.
2001 Annual Radioactive Effluent Releases Report for TMI 5928-02-20095 Changes to the Process Control Program and the Offsite Dose Calculation Manual during 2001, And a listing of new locations for dose calculations and/or environmental monitoring identified by the land use census
- 1. Changes to the Process Control Program Section 6.8.1 of the TMI-1 Technical Specifications requires that a procedure be established, implemented and maintained for the Process Control Program Implementation. TMI procedure 1104-281 (Waste Solidification Process Control Program) had been the document used to ensure that waste would be processed to meet waste stability requirements of 10 CFR 61.56 prior to disposal. Procedure 1104-281 was used in conjunction with operating procedures 11 04-28A(Evaporator Concentrate Processing) andl 104 -28C (Primary Resin and Precoat Processing) to ensure that radioactive wastes would be solidified or dewatered in compliance with 10 CFR Parts 20,61,71 ,State Regulations, burial ground requirements and other requirements that govern the disposal of radioactive waste. With TMI now part of a much larger organization, a goal of standardizing radioactive waste handling procedures was undertaken across the Exelon Fleet. The result has been a new Process Control Program for Radioactive Waste ,Procedure RW-AA-1 00, implemented at TMI on August 17, 2001. This procedure now looks the same at all of the Exelon operated plants. The advantage to TMI, is that now the boundaries and parameters for the preparation of procedures for processing ,sampling, analysis, packaging, storage and shipment of solid radwaste for compliance with local, state, federal, and burial site requirements are found in the same document. Previously these requirements were found throughout many documents, making it somewhat cumbersome to ensure documented compliance with the applicable regulations for a given waste stream. In conclusion, TMI is still applying the same process and bounding conditions for the preparation of radioactive waste for transportation and disposal as the previous version of the Process Control Program. The new procedure covers all radioactive waste generated at this station in one document versus being addressed over many procedures, thus making documented compliance with the federal, state, local, and burial site criteria much easier to monitor.
- 2. Changes to the Offsite Dose Calculation Manual during 2001 The Offsite Dose Calculation Manual (ODCM) was modified twice during 2001. These changes did not reduce the accuracy or reliability of dose calculations or setpoint determinations. The level of effluent controls required by 10 CFR 20.1301, 40 CFR 190, 10 CFR 50.36a, and Appendix I to 10 CFR 50 was not reduced and the accuracy or reliability of effluent, dose or setpoint calculations was not adversely impacted for the reasons stated below.
Revision 21 of the ODCM was issued on January 19, 2001. Revision 21 made the following changes to the ODCM:
"* Eliminated references to GPU Nuclear.
"* Changed the title of Director Operations and Maintenance to Plant Manager.
"* Clarifies the TMI-2 effluent flow rate as a monitoring device, since this recorder sums the flows from individual measuring devices. It also clarifies the available compensatory action if this monitoring device is out of service.
- Clarifies that releases from the Waste Evaporator Condensate Storage Tanks (WECST) uses 20% of ODCM liquid concentration limits for tritium and 10% for other isotopes as an administrative means of ensuring compliance with ODCM Control 2.2.1.1. The limits specified in ODCM Control 2.2.1.1 are not affected.
Revision 22 of the ODCM was issued on May 4, 2001. Revision 22 made the following changes to the ODCM:
"* Eliminates the need to change the alarm setpoint for RM-L-6 each time a WECST is released.
"* Changes "National Bureau of Standards" to "National Institute of Standards and Technology."
"* Added typical flow rates for the gaseous release points in buildings located outside the "power-block."
- 3. A listing of new locations for dose calculations and/or environmental monitoring identified by the land use census Based on the results of the 2001 land use census, no changes to the radiological environmental monitoring program or the dose model are required.

2001 Annual Radioactive Effluent Releases Report for TMI 5928-02-20095 Assessment of Radiation Doses Due to Radioactive Liquid and Gaseous Effluents Released from TMI during 2001 TMI-1 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 2001 TMI-1 releases of gaseous and liquid effluents.
Provided below is a brief explanation of the table.
A. Liquid (Individual)
Calculations were performed on the four age groups and eight organs recommended in Regulatory Guide 1.109. The pathways considered for TMI-1 were the consumption of drinking water and fish and standing on the shoreline influenced by TMI-1 effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The "critical receptor" or Receptor I was that individual who 1) consumed Susquehanna River water from the nearest downstream drinking water supplier (Wrightsville Water Supply), 2) consumed fish residing in the vicinity of the TMI-1 liquid discharge outfall and 3) occupied an area of shoreline influenced by the TMI-1 liquid discharge.
For 2001, the calculated maximum whole body (or total body) dose from TMI-1 liquid effluents was 1.60E-1 mrem to an adult (line 1). The maximum organ dose was 2.41 E-1 mrem to the liver of a teen (line 2).
B. Gaseous (Individual)
There were six major pathways considered in the dose calculations for TMI-1 gaseous effluents. These were: (1) plume exposure (2) inhalation, consumption of; (3) cow milk, (4) vegetables and fruits, (5) meat, and (6) standing on contaminated ground. Real-time meteorology was used in all dose calculations for gaseous effluents.
Lines 3 and 4 present the maximum plume exposure at or beyond the site boundary. The notation of "air dose" is interpreted to mean that these doses are not to an individual, but are considered to be the maximum doses that would have occurred at or beyond the site boundary. The table presents the distance in meters to the location in the affected sector (compass point) where the theoretical maximum plume exposures occurred. The calculated maximum plume exposures were 9.85E-4 mrad and 1.26E-3 mrad for gamma and beta, respectively.
The maximum organ dose due to the release of iodines, particulates and tritium from TMI-1 in 2001 was 1.08E-2 mrem to the thyroid of an child residing 2150 meters from the site in the NNE sector (line 5). This dose again reflects the maximum exposed organ for the appropriate age group.
C. Liquid and Gaseous (Population)
Lines 6 - 9 present the person-rem doses resulting from 2001 TMI-1 liquid and gaseous effluents. These doses were summed over all pathways and the affected populations. The person-rem doses from liquid effluents were based upon the population encompassed within the region from the TMI-1 outfall extending down to the Chesapeake Bay (approximately 5,000,000 people). The person-rem doses from gaseous effluents were based upon the 1980 population and considered the population out to a distance of 50 miles around TMI (approximately 2,200,000 people).
Population doses were summed over all distances and sectors to give an aggregate dose.
The calculated maximum whole body dose to the affected population from TMI-1 liquid effluents was 1.03E+1 person-rem. The maximum critical organ population dose from liquid effluents was 1.04E+1 person-rem to the liver. TMI-1 gaseous effluents resulted in a whole body population dose of 4.99E-1 person-rem and a maximum critical organ population dose of 4.99E-1 person-rem to the liver, thyroid, kidney, lung and GI tract.
For 2001, TMI-1 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly ODCM dose limits.

TMI-2 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 2001 TMI-2 releases of gaseous and liquid effluents.
Provided below is a brief explanation of the table.
A. Liquid (Individual)
Calculations were performed on the four age groups and eight organs recommended in Regulatory Guide 1.109. The pathways considered for TMI-2 were the consumption of drinking water and fish and standing on the shoreline influenced by TMI-2 effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The "critical receptor" or Receptor 1 was that individual who 1) consumed Susquehanna River water from the nearest downstream drinking water supplier (Wrightsville Water Supply), 2) consumed fish residing in the vicinity of the TMI-2 liquid discharge outfall and 3) occupied an area of shoreline influenced by the TMI-2 liquid discharge.
For 2001, the calculated maximum whole body (or total body) dose from TMI-2 liquid effluents was 4.74E-4 mrem to an adult (line 1). The maximum organ dose was 7.53E-4 mrem to the liver of a teen (line 2).
B. Gaseous (Individual)
There were six major pathways considered in the dose calculations for TMI-2 gaseous effluents. These were: (1) plume exposure (2) inhalation, consumption of; (3) cow milk, (4) vegetables and fruits, (5) meat, and (6) standing on contaminated ground. Real-time meteorology was used in all dose calculations for gaseous effluents.
Since there were no noble gases released from TMI-2 during 2001, the gamma and beta air doses (lines 3 and 4, respectively) were zero.
The maximum organ dose due to the release of particulates and tritium from TMI-2 in 2001 was 4.80E-5 mrem to the liver, total body, thyroid, kidney, lung and GI tract of a child residing 2000 meters from the site in the SE sector (line 5).
C. Liquid and Gaseous (Population)
Lines 6 - 9 present the person-rem doses resulting from 2001 TMI-2 liquid and gaseous effluents. These doses were summed over all pathways and the affected populations. The person-rem doses from liquid effluents were based upon the population encompassed within the region from the TMI-2 outfall extending down to the Chesapeake Bay (approximately 5,000,000 people). The person-rem doses from gaseous effluents were based upon the 1980 population and considered the population out to a
distance of 50 miles around TMI (approximately 2,200,000 people).
Population doses were summed over all distances and sectors to give an aggregate dose.
The calculated maximum whole body dose to the affected population from TMI-2 liquid effluents was 2.82E-4 person-rem. The maximum critical organ population dose from liquid effluents was 5.97E-4 person-rem to the bone. TMI-2 gaseous effluents resulted in a whole body population dose of 3.67E-3 person-rem and a maximum critical organ population dose of 3.67E-3 person-rem to the liver, thyroid, kidney, lung and GI tract.
For 2001, TMI-2 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly ODCM dose limits.

2001 Annual Radioactive Effluent Releases Report for TMI 5928-02-20095 Assessment of Radiation Doses from Liquid and Gaseous Effluents Releases to Members of the Public within the TMI Site Boundaries during 2001 The Offsite Dose Calculation Manual requires an assessment of the radiation doses from radioactive liquid and gaseous effluents to members of the public due to their activities inside the site boundary during the reporting period.
The following are the assumptions made in this assessment:

The 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> is based upon shoreline recreation period given in Table E-5, of Regulatory Guide 1.109.
- 2. The individual is standing next to a radiologically controlled area, where the dose rate is 0.5 mR/hr. In areas where the dose rate is greater than 0.5 mR/hr, the area would be posted as a restricted area.
- 3. Liquid effluents are not a pathway to the individual on site.
- 4. The maximum airborne effluent per hour is characterized by Release G200110016, which is a RB purge. This effluent release had the highest concentration of radionuclides released into the air for year 2001. (Ar-41 1.1 E-6 ptCi/cc, Xe-1 33 3.72E-6 MCi/cc, and H-3 1.37E-6 pCi/cc)
- 5. Highest dispersion factor for gaseous effluents to personnel outside restricted area is 7.61E-5 sec/m3 for the 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> used. This is the value used in Final Safety Analysis Report section 2.5.4.2.1, Containment release to Yard intake. This intake is close to the protected area and is close to where the Reactor Building (Containment) would release.
The maximum total body dose to an individual is 34 mrem.
2001 Annual Radioactive Effluent Releases Report for TMI 5928-02-20095 Assessment of Radiation Dose to Most Likely Exposed Real Individual per 40 CFR 190 Dose calculations were performed to demonstrate compliance with 40 CFR 190 (ODCM Part IVSection 2.10). Gaseous and liquid effluents released from TMI-1 and TMI-2 in 2001 resulted in maximum individual doses (regardless of age group) of 0.02 mrem to the thyroid and 0.25 mrem to any other organ including the whole (total) body. The direct radiation component was determined using the highest quarterly fence-line exposure rate as measured by an environmental TLD, and subtracting from it, the lowest quarterly environmental TLD exposure rate.
Based on the maximum exposure rate of 6.1 mR/standard month, a person residing at the fence-line for 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> (shoreline exposure from Reg. Guide 1.109) received an exposure of 0.56 mR. Based on the lowest exposure rate of 3.5 mR/standard month and converting it by the same method yielded a background exposure of 0.32 mR.
Therefore, the net exposure from direct radiation from TMINS was 0.24 mR. Combining the direct radiation exposure (assumed to be equal to dose) with the maximum organ doses from liquid and gaseous releases, the maximum potential (total) doses were 0.26 mrem to the thyroid and 0.49 mrem to any other organ. Both doses were well below the limits specified in 40 CFR 190.
0 2001 Annual Radioactive Effluent Releases Report for TMI 5928-02-20095 Deviation from the ODCM Sampling and Analysis Regime during 2001 There was one deviation from the effluent sampling and analysis regime specified in the TMI Offsite Dose Calculation Manual during 2001.
The deviation was not obtaining a grab sample on a sump prior to discharging that sump. A condition report (TMI's corrective action system) was submitted as a result of the missed sample.
The maximum concentration value for the same type of water that was obtained during the month of release was used to account for the activity discharged. The dose and activity of this discharge is an insignificant value when compared to the plant's annual effluent.

Offsite Dose Calculation Manual (ODCM) 22 INTRODUCTION The OFFSITE DOSE CALCULATION MANUAL (ODCM) is a supporting document of the Three Mile Island Nuclear Station (TMI) Unit I and Unit 2 PDMS Technical Specifications and implements TMI radiological effluent controls.
The ODCM contains the controls, bases, and surveillance requirements for liquid and gaseous radiological effluents.
In addition, the ODCM describes the methodology and parameters to be used in the calculation of off-site doses due to radioactive liquid and gaseous effluents. This document also describes the methodology used for calculation of the liquid and gaseous effluent monitoring instrumentation alarm/trip set points. Liquid and Gaseous Radwaste Treatment System configurations are also included.
The ODCM also is used to define the requirements for the TMI radiological environmental nr9Mting program (REMP) and contains a list and graphical description of the specific sample locations use EMP.
The ODCM is maintained at the Three Mile Island (TMI) site for use as a reference did training document of accepted methodologies and calculations. Changes in the calculation methods o ra ts will be incorporated into the ODCM to ensure the ODCM represents the present methodology in al le reas. Changes to the ODOM will be implemented in accordance with the TMI-1 and TMI-2 PDMS ech Td 2ecifications.
The ODCM follows the methodology and models suggested by NUREG-0133,\ Regulatory Guide 1.109, Revision 1 for calculation of off-site doses due to plant effluent releases. Simp -yingassumptions have been applied in this manual where applicable to provide a more workable docubr ent for implementation of the Radiological Effluent Controls requirements.
TMl implements the TMI Radiological Effluent Controls Pr iman egulatory Guide 1.21, Revision I (Annual Radioactive Effluent Release Report) requirements by A puterized system used to determine TMI effluent releases and to update cumulative effluent doses.

It permits an allowable ensio the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operting c d ons that may not be suitable for conducting the surveillance; e.g.,
transient co nditions or other girpg su'eillance or maintenance activities. It also provides flexibility to accommodate the length of le for surveillances that are specified to be performed at least once each REFUELING INTERVAL. It is tended X that this provision be used repeatedly as a convenience to extend surveillance intervals beyond th specified for surveillances that are not performed once-each REFUELING INTERVAL. Likewise, it is not the intent that REFUELING INTERVAL surveillances be performed during power operation unless it is consistent with safe plant operation. The limitation of Section 1.13 is based on engineering judgement and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the Surveillance Requirements. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance interval.

Offsite Dose Calculation Manual (ODCM) 22 2.0 LIQUID EFFLUENT DOSE ASSESSMENT 2.1 Liquid Effluents - 10 CFR 50 Appendix I The dose from liquid effluents results from the consumption of fish and drinking water. The location of the nearest potable water intake is PP&L Brunner Island Steam Electric Station located downstream of TMI. The use of the flow of the Susquehanna River as the dilution flow is justified based on the complete mixing in the river prior to the first potable water supply, adequately demonstrated by flume tracer die studies and additional liquid effluent release studies conducted using actual TMI-1 tritium releases. Other pathways contribute negligibly at Three Mile Island. The dose contribution from all radionuclides in liquid effluents released to the unrestricted area is calculated using the following expression:
Dose j (At)X (C!) X + AiiXFFDJX D (eq2.1) where:
Dose j = the cumulative dose commitment to the total or an organ, j, from the liquid effluents for the total time period, in mrem. 4 At = the length of the time period of actuall leases, over which C, and f are averaged for all liquid releases, in hours.
C,= the average concentration of nucli , i, in undiluted liquid effluent during time period For Fe-55, Sr-89, Sr- r to batch releases conservative concentration valu .i. be eld in the initial dose calculation based on similar past plant o9,*ins. LLD values are not used in dose calculations. i*
f= un *utdl waste flow, in gpm." "
FD = p di ion water flowrate during the period of release, in gpm FR = actual river flowrate during the period of release or average river flowrate for the month the release is occurring, in gpm.
DF = dilution factor as a result of mixing effects in the near field of the discharge structure of 0.2 (NUREG 0133) or taken to be 5 based on the inverse of 0,2.
AWij and AFij = the site-related ingestion dose commitment factor to the total body or any organ, j, for each identified principle gamma and beta emitter, in mrem/hr per tiCi/ml. AW is the factor for the water pathway and AF is the factor for the fish pathway.
97
Number TMI - Unit I Radiological Controls Procedure 6610-PLN-4200.01 Title Revision No.
Offsite Dose Calculation Manual (ODCM) 22 Values for AWij are determined by the following equation:
AW11 = (1.14E5) x (Up) x (DF 1 ) (eq 2.2) where:
1.14E5 = (1.OES pCil/!Ci) x (1.0E3 mllkg) - (8760 hr/yr)
Uw= Water consumption rate for adult is 730 kglyr (Reg. Guide 1.109, Rev. 1).
DFij = ingestion dose conversion factor for radionuclide, i, for adults total body and for "worst case" organ, j, in mremfpCi, from Table 2.1 (Reg. Guide 1.109)"
Vwalues for AF11 are determined by the following equation:
AFij = (1.14E5) x (Ut) x (DFj) x (BFi) (eq 2.2.2) wthere:
1.14E5 = defined above Uf= adult fish consumption, assumed to b 21 kg/yr (Reg. Guide 1.109, Rev. 1).
DFij = ingestion dose conversion factor onuclide, i, for adult total body and for 'Worst case" organ, j, in mrernpCi,!? fable (Reg. Guide 1.109, Rev. 1).
BFi = Bioaccumulation factor f o lide, i, in fish, in pCilkg per pCi/L from Table 2.2 (Reg.
Guide 1.109, Rev. 1).
2.2 TMI Liquid Radwaste Syste 0 Ca cs Once/Month ODCM Part I Control 2.d1 .- d '*1-2 PDMS Tech Spec Section 6.7.4.a.6 requires that appropriate portions Ifti'Tiqutzd radwaste treatment system shall be used to reduce the radioactive materials in liquid rtes i to their discharge when the monthly projected doses due to the liquid effluent releas from a unit to unrestricted areas would exceed 0.06 mrem to the total body or 0.2 mrem toan rgart* any calendar month. The following calculational method is provided for performing o projection.
At least once per month, the total dose from all liquid releases for the quarter-to-date will be divided by the number of days into the quarter and multiplied by 31. Also, this dose projection shall include the estimated dose due to any anticipated unusual releases during the period for which the projection is made. If this projected dose exceeds 0.06 mrem total body or0.2 mrem any organ, appropriate portions of the Liquid Radwaste Treatment System, as defined in Section 3.1, shall be used to reduce radioactivity levels prior to release.
At the discretion of Radiological Engineering, time periods other than the current quarter-to-date may be used to project doses if the dose per day in the current quarter-to-date is not believed to be representative of the dose per day projected for the next month.

Offsite Dose Calculation Manual (ODCM) 22 2.3 Alternative Liquid Dose Calculational Methodology As an alternative, models in, or based upon, those presented in Regulatory Guide 1.109 (Rev. 1) may be used to make a comprehensive dose assessment. Default parameter values from Reg.
Guide 1.109 (Rev. 1) and/or actual site specific data are used where applicable.
As an alternative dose calculational methodology TMI calculates doses using SEEDS (simplified environmental effluent dosimetry system).
The onsite and SEEDS calculational models use actual liquid release data with actual monthly Susquehanna River flow data to assess the dispersion of effluents in the river.

Offsite Dose Calculation Manual (ODCM) 22 4.6 Control of Gaseous Effluent Releases TMI gaseous effluent combined releases are controlled (per ODCM Part I for TMI-I and ODCM Part II for TMI-2) by effluent samplingand radiation monitor set points. These measures assure that releases from the various vents do not combine to produce dose rates at the site boundary exceeding the most restrictive of 500 mrem per year to the total body or 3000 mrem per year to the skin, and 1500 mrem per year to the thyroid. This is done by restricting simultaneous releases and by limiting the dose rates that may be contributed by the various vents at any time. The various vent radiation monitor set points are each based on fractions of the above limits and do not exceed the above limits when summed together. These effluent radiation monitor set points are calculated using the methodology described in equations 4.1.1, or 4.1.2 and 4.2. The actual set points are then listed in TMI-1 Operations Procedure 1101-2.1.
The radioactive content of each batch of gaseous waste is determine N or ase by sampling and analyses in accordance with ODCM. Part I for TMI-1 and ODC a II for MI-2. The results of pre-release analyses are used with the calculational methods in ctio1-4l and 4.2 to assure that the dose rates at the site boundary are maintained below the Up NO M Part I for TMI-1 and ODCM Part II for TMI-2.
Post-release analyses of samples composited from batch an r'tinuous releases are performed in accordance with ODCM Part I for TMI-I and ODCM Part II forM 1-2. The results of the analyses 0
are used to assure that the dose rates at the site undary are maintained within the limits of ODCM Part I for TMI-1 and ODCM Part I1for TMI-2.
