THREE MILE ISLAND NUCLEAR STATION UNIT 1 AND UNIT 2 OPERATING LICENSE NO. DPR-50 AND POSSESSION ONLY LICENSE NO. DPR 73 DOCKET NOS. 50-289 AND 50-320 COMBINED 2000 ANNUAL RADIOACTIVE EFFLUENT RELEASES REPORT The Annual Radioactive Effluent Releases Report required by TMI-1 Technical Specification 6.9.4.1, TMI-2 Technical Specifications 6.8.1.2, and 6.12, and the Off-Site Dose Calculation Manual Part 4, Section 2.1 is enclosed. contains a summary of the quantities of radioactive liquid and gaseous effluents and on solid waste released from the site as outlined in Reg. Guide 1.21, Rev. 1, with data summarized a quarterly basis following the format of Appendix B thereof.

report Attachment 2 contains information for each type of solid waste shipped offsite during the by period including the container volume, total curie quantity (specified as determined or measurement or estimate), principal radionuclides (specified as determined by measurement estimate), type of waste, type of shipment and solidification agent(s).

areas of Attachment 3 includes a summary of unplanned releases from the site to unrestricted radioactive materials in gaseous and liquid effluents made during the reporting period.

Attachment 4 describes any changes made during 2000 to the Process Control Program (PCP) documents or to the Offsite Dose Calculation Manual (ODCM) and a listing of new locations for to dose calculations and/or environmental monitoring identified by the land use census pursuant Part 3, Section 8.2 of the ODCM.

the TMI Attachment 5 reports all instrumentation not returned to operable status within 30 days per ODCM Part 1, Sections 2.1.1 .b and 2.1.2.b and Part 2, Section 2.1.2.b.

of Attachment 6 is an annual summary of hourly meteorological data collected for 2000 in the form joint frequency distribution of wind speed, wind direction and atmospheric stability.

5928-01-20113 Page 2 of 2 is an assessment of the radiation doses due to the radioactive liquid and gaseous effluents released from the respective unit during 2000. is an assessment of the radiation doses from the radioactive liquid and gaseous effluents to members of the public due to their activities inside the site boundary during 2000. is an assessment of the radiation doses to the likely most exposed real individual from reactor releases and other nearby uranium fuel cycle sources including doses from primary effluent pathways and direct radiation for 2000. This assessment shows conformance with 40 CFR 190 "Environmental Radiation Protection Standards for Nuclear Power Operation." 0 is a summation of deviations from the sampling and analysis regime specified in the ODCM for TMI-1 and TMI-2. There were no deviations from the sampling and analysis regime specified in the ODCM for TMI-1 or TMI-2 during 2000. is a copy of the TMI Offsite Dose Calculation Manual (ODCM), revision 20, which was current as of December 31, 2000. There was one revision made to the ODCM during 2000. Revision 20 was issued on November 8, 2000. is a copy of the procedure change request that modified the ODCM from revision 19 to revision 20.

2000 Annual Radioactive Effluent Releases Report for TMI 5928-01-20113 Changes to the Process Control Program and the Offsite Dose Calculation Manual during 2000, And a listing of new locations for dose calculations andlor environmental monitoring identified by the land use census

1. Changes to the Process Control Program There were no changes made to Process Control Program (PCP) documents in 2000.

2. Changes to the Offsite Dose Calculation Manual during 2000 The Offsite Dose Calculation Manual (ODCM) was modified once during 2000. This change 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 20 of the ODCM was issued on November 8, 2000. Revision 20 made the following changes to the ODCM:

. This PCR was submitted to add station K1 5-3 and delete station K1 5-2. Station K1 5-3 is a new control milk station being added because the station at K1 5-2 is ceasing dairy operations.

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 2000 Three Mile Island Nuclear Station land use census, there were no locations identified that yielded a calculated dose or dose commitment greater than the values currently being calculated in ODCM Part I Surveillance 3.2.2.3.1. Additionally, there were no locations identified that yielded a calculated dose or dose commitment 20% greater than at a location from which samples are currently being obtained in accordance with ODCM Part III Table 8.1.

2000 Annual Radioactive Effluent Releases Report for TMI 5928-01-20113 Assessment of Radiation Doses Due to Radioactive Liquid and Gaseous Effluents Released from TMI during 2000 TMI-1 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 2000 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 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-1 liquid discharge outfall and 3) occupied an area of shoreline influenced by the TMI-1 liquid discharge.

For 2000, the calculated maximum whole body (or total body) dose from TMI-1 liquid effluents was 3.57E-2 mrem to an adult (line 1). The maximum organ dose was 5.18E-2 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 2.96E-5 mrad and 1.51 E-4 mrad for gamma and beta, respectively.

The maximum organ dose due to the release of iodines, particulates and tritium from TMI-1 in 2000 was 1.61 E-2 mrem to the thyroid of an infant residing 2150 2000 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 2000 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 2.34E0 person-rem. The maximum critical organ population dose from liquid effluents was 2.34E0 person-rem to the liver. TMI-1 gaseous effluents resulted in a whole body population dose of 1.83E-1 person-rem and a maximum critical organ population dose of 2.82E-1 person-rem to the thyroid.

For 2000, 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 2000 TMH-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 2000, the calculated maximum whole body (or total body) dose from TMI-2 liquid effluents was 1.27E-3 mrem to an adult (line 1). The maximum organ dose was 2.0 1E-3 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 2000, 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 2000 was 4.56E-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 2000 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 2.59E-4 person-rem. The maximum critical organ population dose from liquid effluents was 5.30E-4 person-rem to the bone.

TMI-2 gaseous effluents resulted in a whole body population dose of 3.46E-3 person-rem and a maximum critical organ population dose of 3.46E-3 person-rem to the liver, thyroid, kidney, lung and GI tract.

For 2000, TML-2 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly ODCM dose limits.

2000 Annual Radioactive Effluent Releases Report for TMI 5928-01-20113 Assessment of Radiation Doses from Liquid and Gaseous Effluents Releases to Members of the Public within the TMI Site Boundaries during 2000 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 public did not have unrestricted access to the TMI site during 2000. Therefore no assessment of this dose is applicable.

2000 Annual Radioactive Effluent Releases Report for TMI 5928-01-20113 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 IV Section 2.10). Gaseous and liquid effluents released from TMI-1 and TMI-2 in 2000 resulted in maximum individual doses (regardless of age group) of 0.02 mrem to the thyroid and 0.06 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 8.5 mR/standard month, a person residing at the fence-line for 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months (shoreline exposure from Reg. Guide 1.109) received an exposure of 0.78 mR. Based on the lowest exposure rate of 3.2 mR/standard month and converting it by the same method yielded a background exposure of 0.29 mR. Therefore, the net exposure from direct radiation from TMINS was 0.49 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 0.51 mrem to the thyroid and 0.55 mrem to any other organ. Both doses were well below the limits specified in 40 CFR 190.

0 2000 Annual Radioactive Effluent Releases Report for TMI 5928-01-20113 Deviation from the ODCM Sampling and Analysis Regime during 2000 There were no deviations from the effluent sampling and analysis regime specified in the TMI Offsite Dose Calculation Manual during 2000.

Offsite Dose Calculation Manual (ODCM) J 20 INTRODUCTION The OFFSITE DOSE CALCULATION MANUAL (ODCM) is a supporting document of the GPUNC Three Mile Island Nuclear Station (TMINS) Unit 1 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 TMINS radiological environmental itoring program (REMP) and contains a list and graphical description of the specific sample locations used i the MP.

The ODCM is maintained at the Three Mile Island (TM[) site for use as a reference gun*dt ig document of accepted methodologies and calculations. Changes in the calculation methods or rarr, rs will be incorporated into the ODCM to ensure the ODCM represents the present methodology In all at II le as. GPUNC initiated changes to the ODCM will be implemented in accordance with the TMI-1 and T RIS Technical Specifications.

The ODCM follows the methodology and models suggested by NUREG-0 pnd egulatory Guide 1.109, Revision 1 for calculation of off-site doses due to plant effluent releases. Slmp[*i9 g assumptions have been applied in this manual where applicable to provide a more workable document for implementation of the Radiological Effluent Controls requirements.

GPUN implements the TMI Radiological Effluent Controls P ram Regulatory Guide 1.21, Revision 1 (Annual Radioactive Effluent Release Report) requirements by us, f corn teized system used to determine TMI effluent releases and to update cumulative effluent doses.

It permits an allowable ext nsiof e normal surveinlance interval to facilitate surveillance scheduling and consideration of plant operatinw!pnditih hat may not be suitable for conducting the surveillance; e.g.,

transient conditions or other on ing s" lance or maintenance activities. It also provides flexibility to accommodate the length of a e cle r surveillances that are specified to be performed at least once each REFUELING INTERVAL. It 'q"ibded that this provision be used repeatedly as a convenience to extend surveillance intervals beyond thLpeclfled for surveillances that are not performed once each REFUELING INTERVAL. Likewise, it is not th intent that REFUELING INTERVAL surveillances be performed during power operation unlessit 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.

E x V x 2.22 x 106 x Y x exp (-%At)

Where:

LLD is the "a priori" lower limit of detection as defined above rie per unit mass or volume),

Sb is the standard deviation of the background counting rate or the counting rate of a blank sample as appropriate (as counts per minute),

E is the counting eff'idency (as counts per disi ;ltion),

V Is the sample size (in units of mass or lu 2.22 x 106 is the number of disinteg io plnteue per microcurie, Yis the fractional radiochemi Ild en applicable),

X Is the radioactive de o ant or the particular radionuclide, and At is the elapsed ti betw $~midpoint of sample collection and time of counting.

It should be racmsZed that the LLD is defined as an "a priori" (before the fadc) limit representing the capability of a miasurement system and not as an "aposteriori" (after the fact) limit for a particular measurement.

b. A composite sample is one in which the quantity of liquid sampled is proportional to the quantity of liquid waste discharged and In which the method of sampling employed results in a specimen which is representative of the liquids released.

c. To be representative of the quantities and concentrations of radioactive materials in liquid effluent, samples shall be collected continuously In proportion to the rate of flow of the effluent stream. Prior to analyses, all samples taken for the composite shall be thoroughly mixed In order for the composite sample to be representative of the effluent release-51

These liquid release point radiation monitors and sample points are shown in Table 1.1. (The TMI outfall radiation monitor, RM-L7, Is also listed for information only.)

TMI-2 does not have any required liquid radiation monitors, but does utilize RM-L12, and RM-L7 for release of liquid waste.

1.2.1 RM-L6 RM-L6 is an off-line system, monitoring radioactive batch discharges from the TMI-1 liquid radwaste system (see Figure 1.1). These batch releases are sae nd analyzed per site procedures prior to release. The release rate is based on I sing ne of two Waste Evaporator Condensate Storage Tanks (WECST) at a flow ic vl.aed less than 10%,

often times the 10 CFR 20 concentrations to radionudid trations in the unrestricted area, Including conservative default values - r-90, and Fe-55.

The release flow rate used is the most restrictive 9 thre wrates calculated for each liquid batch release, perthe approved plant protre.

Three Diution Factors (DF) are calculated to ultimat'y calculate the batch release flow rate. These three DF's are calculated t. 1) insure each radionuclide released to the unrestricted area is less than 10 per n of ten times the IOCFR20 radionuclide concentrations, 2) ensure each liquidWa jlease boron concentration to the river will not exceed 0.7 ppm, and 3), en,0ten ti es the IOCFR20 concentration for Cesium-137 (1E-5 jiCi/ml) will not be exceia- tfl- on the calculated high alarm set point and the expected response of R th' oncentration of Cs-1 37.

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 (cj)X A jXFR)+(FIXFD (eq 2.1) where:

Dose j = the cumulative dose commitment to the total bo or organ, j, from the liquid effluents ror the total time period, in mrem.

at = the length of the time period of actual releases, over'which Ci and f are averaged for all liquid releases, in hours.

2.2 TMI Liquid Radwaste System Dose Calcs e/Mo ODCM Part I Control 2.2.1.3 and T S Tech Spec Section 6.7.4.a.6 requires that appropriate portions of the liquid ra ast t ment system shall be used to reduce the radioactive materials in liquid wastes prior t dis arge when the monthly projected doses due to the liquid effluent releases from each u o un ed areas would exceed 0.06 mrem to the total body or 0.2 mrem to any organ in r month. The following calculational method is provided for performing this dose pr o on.

At least once per nth, th al dose from all liquid releases for the quarter-to-date will be divided by the number o aa nt the quarter and multiplied by 31. Also, this dose projection shall include the estimated dtqe due any anticipated unusual releases during the period for which the projection 19 1 t is projected dose exceeds 0.06 mrem total body or 0.2 mrem any organ, appropriate po ' Nf the Liquid Radwaste Treatment System, as defined In Section 3.1, shall be used to reduce rlioactivlty levels prior to release.

At the discretion of Radiological Engineering, lime periods other than the current quarter-to-date may be used to project doses Ifthe 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) 20 4.6 Control of Gaseous Effluent Releases TMI gaseous effluent combined releases are controlled (per ODCM Part I for TMI-1 andODCM Part II for TMI-2) by effluent sampling and 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 nmem 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 determined pr r e se by sampling and analyses in accordance with ODCM Part I for TMI-1 and ODCM PfI fo .2. The results of pre-release analyses are used with the calculational methods in Se .1 and 4.2 to assure that the dose rates at the site boundary are maintained below the lirnit* Part I for TMI-1 and ODCM Part it for TMI-2.

Post-release analyses of samples composited from batch dcontious releases are performed in accordance with ODCM Part I for TMI-1 and ODCM Part II for -2. The results of the analyses are used to assure that the dose rates at the site boundary are 6raintained within the limits of ODCM Part I forTMl-1 and ODCM Part II for TMI-2.

Offsite Dose Calculation Manual (ODCM) 20 5.3 Gaseous Radioactive System Dose Calculations Once per Month ODCM Part I Control 2.2.2.4 and TMI-2 PDMS Tech Spec Section 6.7.4.a.6 requires that appropriate subsystem of the Gaseous Radwaste Treatment System shall be used to reduce the radioactive materials in gaseous waste priorto their discharge. When the monthly projected doses due to the gaseous effluent releases from the site would exceed:

0.2 mrad to air from gamma radiation; or 0.4 mrad to air from beta radiation; or 0.3 mrem to any organ.

The following calculational method is provided for performing this dose projejn.

At least once per month the gamma air dose, beta air dose and the m org dose for the quarter-to-date will be divided by the number of days into the quarterjduRid by 31. Also, this dose projection shall include the estimated dose due to any anticipate sual release during the period for which the projection is made. If these projected doses r of the values listed above, appropriate portions of the TMI-i Gaseous Waste Trea tern, as defined in Section 6.0, or appropriate portions of the TMI-2 Gaseous uen Jiration System as shown on Figure 4.5, shall be used to reduce radioactivity levels pri tlea.

At the discretion of Radiological Engineering, lime periods oth than the current quarter-to-date may be used to project doses if the dose per day

the current quarter-to-date is not believed to be representative of the dose per day projected ft th next month.

Offsite Dose Calculation Manual (ODCM) 20 5.4 Alternative Dose Calculational Methodologies for Gaseous Effluents As an alternative to the methods described above, the models intor based upon, those presented in Regulatory Guide 1.109 (Rev. 1) may be used to make a comprehensive dose assessment. Default parameter values from Regulatory Guide 1.109 (Rev. 1) and/or actual site specific data can be used where applicable.

The onsite, on-line computerized system fortracking gaseous effluent dose uses annual average gaseous dispersion factors. As an alternative dose calculational methodology. GPU Nuclear calculates doses using an advanced class A'W dispersion model called SEEDS (simplified environmental effluent dosimetry system).

This model incorporates the guidelines and methodology set forth in USNRQ latory Guide 1.109, and uses actual hourly meteorological information matched to he ti of releases to more accurately assess the dispersion of effluents inthe atmosphere.^0 'o'his assessment of dispersion with TMINS effluent data for each unit, postulated maxlu ypothetical doses to the public are calculated.

The best information from the door-to-door survey, aerial surveys, or consulting with local agricultural authorities shall be used. This census satisfies the requirements of Section IVB.3 of Appendix I to2 10 CFR 50. Restricting the census to gardens of greater than 500 square feet (50 m ) provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kglyr) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used: 1) thg0%of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce ndl bbage), and 2) a vegetation yield of 2 kg/square meter. ,

NOTES

1. Inhalation and ingestion dose factors were taken from the indicated source. For each age group, for each nuclide, the organ dose factor used was the highest dose factor for that nuclide and age group in the referenced table.

2. Typically beef cattle are raised all year on pasture. Annual land surveys have indicated that the small number of goats raised within 5 miles typically are used for grass control and not food or milk. Nevertheless, the goats can be treated as full meat sources where present, despite the fact that th ffhbqbers cannot sustain the meat consumption rates of Table E-5, NUREG-0133.

3. Does this change have the potentialto adversely affect nuclearsafety or safe plant operations?

No. As required by Part HI, Section 8.1.3.c of the Offsite Dose Calculation Manual, ODCM, (66 10-PLN-4200.01), control milk sampling station K15-3 is being added to and control milk sampling station K15-2 is being deleted from the Radiological Environmental Monitoring Program (REMP) and Table 8.8 and Map 8.3 of the ODCM. These changes are necessary because milk samples are no longer available from control milk station K15-2, The farmer at this station is ceasing dairy operations. StationK15-3 is a suitable control station because it is located greater than 10 miles from TMINS and located in a non-prevalent wind direction.

The proposed changes (of adding and deleting a control milk sampling station t IftEMP and Table 8.8 and Map 8.3 of the ODCM) do not impact/affect plant systems or ponts that are important to safe plant operations.
