==1.0 INTRODUCTION==
 
Tables 1 through 3 lists the recorded radioactive liquid and gaseous effluents and solid waste shipments for the year, with data summarized on a quarterly basis for both liquids and gases. Table 4A summarizes the estimated radiological dose commitments from all radioactive liquid and gaseous effluents released during the year 2005 in response to the ALARA objectives of 1OCFR50, Appendix I. Also included in Table 4A is the estimate of direct dose from fixed station sources along the limiting west site boundary line. Tables 5A through 6H report the cumulative joint frequency distributions of wind speed, wind direction, and atmospheric stability for the 12-month period, January to December 2005. Radioactive effluents reported in Tables 1 and 2 were used to determine the resulting doses for 2005.As required by ODCM Section 10.1, (Reference
: 1) dose commitments resulting from the release of radioactive materials in liquids and gases during the reporting period were estimated in accordance with the plant's "Off-Site Dose Calculation Manual" (ODCM). These dose estimates were made using a "Method II" analysis as described in the ODCM. A "Method II" analysis incorporates the methodology of Regulatory Guide 1.109 (Reference
: 2) and actual measured meteorological data recorded concurrently with the quarterly reporting period.As required by ODCM Section 10.1, this report shall also include an assessment of the radiation doses from radioactive effluents to member(s) of the public due to allowed recreational activities inside the site boundary during the year. During this reporting period, no recreational activity was permitted and, therefore, there is no associated dose assessment as stated in Section 3.6.Assessment of radiation doses (including direct radiation) to the likely most exposed real member(s) of the public for the calendar year for the purposes of demonstrating conformance with 40CFR1 90, "Environmental Radiation Protection Standards for Nuclear Power Operations," are also required to be included in this report if the conditions indicated in ODCM 3/4.6, "Total Dose," have been exceeded during the year. Since the conditions indicated in the action statement under ODCM 3/4.6 were not entered into during the year, no additional radiation dose assessments are required.
However, Table 4B does provide the combination of doses and dose commitments from plant effluents and direct radiation sources for the limiting member of the public off-site as a demonstration of compliance with the dose standards of 40CFRI90.All calculated dose estimates for members of the public at the site boundary or beyond for the 2005 annual reporting period are below the dose criteria of 1OCFR Part 50, Appendix I, and 40CFRI90.Appendices B through H indicate the status of reportable items per the requirements of ODCM Section 10.1.1
 
===2.0 METEOROLOGICAL===
 
DATA Meteorological data were collected during this reporting period from the site's 300-foot meteorological tower located approximately 2,200 feet northwest of the reactor building, and about 1,400 feet from the plant stack. The 300-foot tower is approximately the same height as the primary plant stack (94 meters) and is designed to meet the requirements of Regulatory Guide 1.23 for meteorological monitoring.
X/Q (annual or long-term average undepleted atmospheric dispersion factors) and D/Q (deposition factors for dry deposition of elemental radioiodines and other particulates) values were derived for all receptor points from the site meteorological record for each quarter using a straight-line airflow model. All dispersion factors have been calculated employing appropriate source configuration considerations, as described in Regulatory Guide 1.111 (Reference 3). A source depletion model as described in"Meteorology and Atomic Energy -1968" (Reference
: 4) was used to generate deposition factors, assuming a constant deposition velocity of 0.01 m/sec for all stack (elevated) releases.
Changes in terrain elevations in the site environment were also factored into the meteorological models as appropriate.
Table 4C lists the distances from the plant stack to the nearest site boundary, resident, and milk animal in each of the 16 principle compass directions as determined during the 2005 land use census. These locations were used in the calculation of atmospheric dispersion factors. The meteorological model was also executed for each calendar quarter to determine the location of the predicted maximum ground level air concentration.
These locations were included in the assessment of effluent doses along with identified points of interest from the annual land use census.2 3.0 DOSE ASSESSMENT
 
===3.1 Doses===
From Liguid Effluents ODCM 3/4.2.2 limits total body (1.5 mrem per quarter, and 3 mrem per year) and organ doses (5 mrem per quarter, and 10 mrem per year) from liquid effluents to a member of the public to those specified in 1OCFR Part 50, Appendix I. By implementing the requirements of 1OCFR Part 50, Appendix I, ODCM 3/4.2.2 assures that the release of radioactive material in liquid effluents will be kept "as low as is reasonably achievable." For periods in which liquid waste discharges actually occur, the exposure pathways that could exist are fish, direct exposure from river shoreline sedimentation, milk and meat via animal ingestion of the Connecticut River water, and meat, milk and vegetable pathways via crop irrigation with water withdrawn from the Connecticut River. Ingestion pathways of drinking water and aquatic invertebrate do not exist down river of the Vermont Yankee plant.There were no recorded liquid radwaste discharges during the report period, and therefore, no dose impact.3.2 Doses From Noble Gases ODCM 3/4.3.2 limits the gamma air dose (5 mrad per quarter, and 10 mrad per year) and beta air (10 mrad per quarter, and 20 mrad per year) dose from noble gases released in gaseous effluents from the site to areas at and beyond the site boundary to those specified in 1OCFR Part 50, Appendix I. By implementing the requirements of 10CFR Part 50, Appendix I, ODCM 3/4.3.2 assures that the releases of radioactive noble gases in gaseous effluents will be kept "as low as is reasonably achievable." Dose estimates due to the release of noble gases to the atmosphere are typically calculated at the site boundary, nearest resident in each of the sixteen principal compass directions, the point of highest off-site ground level air concentration of radioactive materials, and for each of the milk animal locations located within five miles of the plant. For 2005, noble gases were detected in effluents released from the plant stack in the first and third quarters.The maximum estimated quarterly and annual air doses due to noble gases at any of the off-site locations are reported in Table 4A. These estimated air doses are well below the 1OCFR Part 50, Appendix I dose criteria of ODCM 3/4.3.2. Table 4B list the annual dose impact from gaseous effluents (including noble gases) at the overall highest impacted resident location after consideration of all exposure categories (i.e., liquid, gas and fixed radiation sources).
Table 4B provides an estimation of the total annual dose impact associated with the highest exposed member of the public for demonstration of compliance to the dose standard contained in 40CFR Part 190 for the uranium fuel cycle.3
 
===3.3 Doses===
From Iodine-131, Iodine-133.
Tritium. and Radionuclides in Particulate Form With Half-Lives Greater Than 8 Days ODCM 3/4.3.3 limits the organ dose to a member of the public from iodine-131, iodine-133, tritium and radionuclides in particulate form with half-lives greater than 8 days (hereafter called iodines and particulates) in gaseous effluents released from the site to areas at and beyond the site boundary to those specified in IOCFR Part 50, Appendix I (7.5 mrem per quarter, and 15 mrem per year). By implementing the requirements of IOCFR Part 50, Appendix I, ODCM 3/4.3.3 assures that the releases of iodines and particulates in gaseous effluents will be kept "as low as is reasonably achievable." Exposure pathways that could exist as a result of the release of iodines and particulates to the atmosphere include external irradiation from activity deposited onto the ground surface, inhalation, and ingestion of vegetables, meat and milk. Dose estimates were made at the site boundary and nearest resident in each of the sixteen principal compass directions, as well as all milk animal locations within five miles of the plant. The nearest resident and milk animals in each sector were identified by the most recent Annual Land Use Census as required by ODCM 3/4.5.2 (see Table 4C). Conservatively, a vegetable garden was assumed to exist at each milk animal and nearest resident location.
Furthermore, the meat pathway was assumed to exist at each milk cow location since this data category is not part of the annual land use census. Doses were also calculated at the point of maximum ground level air concentration of radioactive materials in gaseous effluents and included the assumption that the inhalation, vegetable garden, and ground plane exposure pathways exist for an individual with a 100 percent occupancy factor.It is assumed that milk and meat animals are free to graze on open pasture during the second and third quarters with no supplemental feeding. This assumption is conservative since most of the milk animals inventoried in the site vicinity are fed stored feed throughout the entire year with only limited grazing allowed during the growing season. It has also been assumed that only 50 percent of the iodine deposited from gaseous effluent is in elemental form (12) and is available for uptake (see p. 6, Reference 2). During the non-growing season (first and fourth quarters), the milk animals are assumed to receive only stored feed. During the growing season (second and third quarters), all animal feed is assumed to be derived from fresh pasture. Usage factors for gaseous effluents are listed by age group and pathway in Table 4D. Table 4E provides other dose model parameter assumptions used in the dose assessments.
The resultant organ doses were determined after adding the contributions from all pathways at each location.
Doses were calculated for the whole body, GI-tract, bone, liver, kidney, thyroid, lung and skin for adults, teenagers, children and infants. The maximum estiniated quarterly and annual organ doses to any age group due to iodines and particulates at any of the off-site receptor locations are reported in Table 4A. These estimated organ doses are well below the 1OCFR Part 50, Appendix I dose criteria of ODCM 3/4.3.3. Table 4B provides an estimation of the total annual dose impact (including contributions from iodine and particulates) associated with the highest exposed member of the public for demonstration of compliance to the dose standard contained in 40CFR Part 190 for the uranium fuel cycle.4
 
===3.4 Whole===
Body Doses in Unrestricted Areas From Direct Radiation The major source of dose in unrestricted areas occurs at the west site boundary, and mainly consisting of direct and skyshine radiation from N-16 decay in the Turbine Building steam cycle during power operations.
Because of the orientation of the Turbine Building on the site, and the shielding effects of the adjacent Reactor Building, only the seven westerly sectors (SSW to NNW)see any significant direct radiation.
A correlation method was derived, based directly on site boundary exposure rate and in-plant Main Steam Line Radiation Monitor measurements, that allows changes in the N-16 carryover in the main steam flow to be directly related to changes in the site boundary dose. This correlation is documented in section 6.11.1 (Equation 6-27a) of the ODCM. This method was used to calculate direct dose at the maximum site boundary location from radiation sources in the steam cycle.The other fixed sources of direct and scatter radiation to the site boundary are from low level radioactive waste stored in the North Warehouse, the Low Level Waste Storage Pad Facility, and old turbine rotors and casings in the Turbine Storage Facility.
The annual dose is based on dose rate measurements in these three storage facilities and determined at the same most restrictive site boundary dose location as that for N- 16 shine from the Turbine Building.The estimated direct radiation dose from all major sources combined for the most limiting site boundary location is listed in Table 4A. These site boundary doses assume a 100 percent occupancy factor, and take no credit for the shielding effect of any residential structure.
Table 4B lists the combination of direct radiation and effluent release doses at the limiting nearest residence for the purpose of demonstrating compliance with the dose standards contained in 40CFR Part 190. For direct radiation, no credit for actual occupancy time is taken (i.e., occupancy is equal to 100%).For 2005, the annual dose limit for the nearest real resident from all station sources (effluents plus fixed radiation sources) was below the 25 nirem total body and organ limit (75 mrem thyroid) of 40 CFR 190.3.5 Doses From On-Site Disposal of Septic Waste. Cooling Tower Silt and Soil Off-Site Dose Calculation Manual, Appendices B, F and I, require that all applications of septage, cooling tower silt and sand/soil within the approved designated disposal areas be limited to ensure the dose to a maximally exposed individual during the period of Vermont Yankee site control be maintained at less than 1 mrem/year to the whole body and any organ. After the period associated with Entergy-Vermont Yankee operational control, the dose to the inadvertent intruder is to be maintained at less than 5 mnrem/year.
The projected dose from on-site disposals of septic waste, cooling tower silt and sand/soil mixes is given in Appendix J of this report.The dose limits applicable for the on-site spreading of materials were met for the single disposal (septic waste) in 2005 and in combination with all past spreadings.
5 3.6 On-Site Recreational Activities During 2005, no access for employees, their families and guests to the boat launching ramp located on-site just north of the intake structure was permitted.
As such, no recreational activities were permitted on-site during the report period and, therefore, no associated dose impact to members of the public.6 REFERENCES

: a. Average gamma energy: Not Applicable
: b. Average beta energy: Not Applicable
: 4. MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY Provided below are the methods used to measure or approximate the total radioactivity in effluents and the methods used to determine radionuclide composition.
: a. Fission and Activation Gases Continuous stack monitors monitor the gross Noble Gas radioactivity released from the plant stack. Because release rates are normally below the detection limit of these monitors, periodic grab samples are taken and analyzed for the gaseous isotopes present. These are used to calculate the individual isotopic releases indicated in Table IB and the totals of Table IA. The error involved in these steps may be approximately
+/-23 percent.b. lodines Continuous isokinetic samples are drawn from the plant stack through a particulate filter and charcoal cartridge.
The filters and cartridges are normally removed weekly and are analyzed for Iodine-131, 132, 133, 134, and 135. The error involved in these steps may be approximately
+/-18 percent.A-2
: c. Particulates The particulate filters described in b. above are also counted for particulate radioactivity.
The error involved in this sample is also approximately
+/-18 percent.d. Tritium ODCM Table 4.3.1 requires as a minimum that grab samples from the plant stack be taken monthly and analyzed for tritium. The stack tritium collection has been upgraded with silica gel columns and continuous sampling of stack effluents.
The error involved in this sample is approximately
+/- 10 percent.e. Waste Oil Prior to issuing the permit to burn a drum of radioactively contaminated waste oil, one liter of the oil is analyzed by gamma spectroscopy to determine concentrations of radionuclides that meet or exceed the LLD for all of the liquid phase radionuclides listed in ODCM Table 4.2.1.Monthly, samples from drums that were issued bum permits are sent to the contracted laboratory for compositing and analysis.
The lab analyzes for tritium, alpha, Fe-55, Sr-89, and Sr-90 on the composite sample.The error involved in this sample is approximately
+/-15 percent.f. Liquid Effluents If radioactive liquid effluents are to be released from the facility, they are continuously monitored.
Measurements are also required on a representative sample of each batch of radioactive liquid effluents released.
For each batch, station records are retained of the total activity (mCi) released, concentration (IiCi/ml) of gross radioactivity, volume (liters), and approximate total quantity of water (liters) used to dilute the liquid effluent prior to release to the Connecticut River.Each batch of radioactive liquid effluents to be released is analyzed for gross gamma and gamma isotopic radioactivity.
A monthly proportional composite sample, comprising an aliquot of each batch released during a month, is analyzed for tritium and gross alpha radioactivity.
A quarterly proportional composite sample, comprising an aliquot of each batch released during a quarter, is analyzed for Sr-89, Sr-90, and Fe-55.A-3
: 5. BATCH RELEASES a. Liquid There were no routine liquid batch releases during the reporting period.b. Gaseous Waste oil was burned during the first quarter and was considered to be a continuous release.The gaseous releases from burning waste oil are treated as either batch or continuous releases based on the total hours of burning in a calendar quarter.All other atmospheric discharges were recorded as continuous elevated releases from the main plant stack.6. ABNORMAL RELEASES a. Liquid There were no non-routine liquid releases during the reporting period.b. Gaseous There were no non-routine gaseous releases (measured) during the reporting period.A-4 APPENDIX B LIQUID HOLDUP TANKS Requirement Response: Technical Specification 3.8.D.I limits the quantity of radioactive material contained in any outside tank. With the quantity of radioactive material in any outside tank exceeding the limits of Technical Specification 3.8.D.1, a description of the events leading to this condition is required in the next annual Radioactive Effluent Release Report per ODCM Section 10.1.The limits of Technical Specification 3.8.D. 1 were not exceeded during this reporting period.B-I APPENDIX C RADIOACTIVE LIQUID EFFLUENT MONITORING INSTRUMENTATION Requirement:
Response: Radioactive liquid effluent monitoring instrumentation channels are required to be operable in accordance with ODCM Table 3.1.1. If an inoperable radioactive liquid effluent monitoring instrument is not returned to operable status prior to a release pursuant to Note 4 of Table 3.1.1, an explanation in the next annual Radioactive Effluent Release Report of the reason(s) for delay in correcting the inoperability are required per ODCM Section 10.1.Since the requirements of ODCM Table 3.1.1 governing the operability of radioactive liquid effluent monitoring instrumentation were met for this reporting period, no response is required.C-1 APPENDIX D RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION Requirement:
Response: Radioactive gaseous effluent monitoring instrumentation channels are required to be operable in accordance with ODCM Table 3.1.2. If inoperable gaseous effluent monitoring instrumentation is not returned to operable status within 30 days pursuant to Note 5 of Table 3.1.2, an explanation in the next annual Radioactive Effluent Release Report of the reason(s) for the delay in correcting the inoperability is required per ODCM Section 10.1.Since the requirements of ODCM Table 3.1.2 governing the operability of radioactive gaseous effluent monitoring instrumentation were met for this reporting period, no response is required.D-1 APPENDIX E RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Requirement:
Response: The radiological environmental monitoring program is conducted in accordance with ODCM Control 3/4.5.1. With milk samples no longer available from one or more of the sample locations required by ODCM Table 3.5.1, ODCM 10.1 requires the following to be included in the next annual Radioactive Effluent Release Report: (1) identify the cause(s) of the sample(s)no longer being available, (2) identify the new location(s) for obtaining available replacement samples and (3) include revised ODCM figure(s) and table(s) reflecting the new location(s).
No changes were needed in the milk sampling locations as specified in ODCM Table 3.5.1 and implemented in ODCM Table 7.1 during the reporting year.E-1 APPENDIX F LAND USE CENSUS Requirement:
Response: A land use census is conducted in accordance with ODCM Control 3/4.5.2.With a land use census identifying a location(s) that yields at least a 20 percent greater dose or dose commitment than the values currently being calculated pursuant to ODCM Control 4.3.3, the new location(s) must be identified in the next Annual Radioactive Effluent Release Report.The Land Use Census was completed during the third quarter of 2005. No significant land use changes from the previous year's census were identified.
As a result, no locations were identified which yielded a 20 percent greater dose or dose commitment than the values currently being calculated pursuant to ODCM Control 4.3.3.F-1 APPENDIX G PROCESS CONTROL PROGRAM Requirement:
Response: ODCM Section i 0. 1 requires that licensee initiated changes to the Process Control Program (PCP) be submitted to the Commission in the annual Radioactive Effluent Release Report for the period in which the change(s) was made.There were no changes made to the Process Control Program during this reporting period.G-1 APPENDIX H OFF-SITE DOSE CALCULATION MANUAL Requirement:
Response: Technical Specification 6.7.B. 1 requires that licensee initiated changes to the Off-Site Dose Calculation Manual (ODCM) be submitted to the Commission in the annual Radioactive Effluent Release Report for the period in which the change(s) was made effective.
There were no changes made to the ODCM during this reporting period.H-1 APPENDIX I RADIOACTIVE LIQUID, GASEOUS, AND SOLID WASTE TREATMENT SYSTEMS Requirement:
Response: ODCM Section 10.4 requires that licensee initiated major changes to the radioactive waste systems (liquid, gaseous, and solid) be reported to the Commission in the annual Radioactive Effluent Release Report for the period in which the evaluation was reviewed by the Plant Operation Review Committee.
There were no licensee-initiated major changes to the radioactive waste systems during this reporting period.I-1 APPENDIX J ON-SITE DISPOSAL OF SEPTIC/SILT/SOIL WASTE Requirement:
Response: Off-Site Dose Calculation Manual, Appendices B, F and I require that the dose impact due to on-site disposal of septic waste, cooling tower silt and sand/soil type materials during the reporting year and from previous years be reported to the Nuclear Regulatory Commission in the annual Radioactive Effluent Report if disposals occur during the reporting year. Entergy -Vermont Yankee will report in the Annual Radioactive Effluent Release Report a list of the radionuclides present and the total radioactivity associated with the on-site disposal activities on the Vermont Yankee site.There was one on-site disposal of septic waste during the reporting year. The total volume of the septic waste spread in 2005 was 11,000 gallons. The total activity spread on the 1.9 acres (southern) on-site disposal field from 2005 spreading and from previous years was as follows: Activity Spread in 2005 Nuclide Mn-54 Co-60 Zn-65 Cs-134 Cs-137 Ce-141 (Ci)1.33E-07 3.80E-08 3.80E-08 1.90E-08 3.80E-08 0.OOE+00 Activity from 2005, plus Activity from All Past Disposals Decayed to 07/26/2005 (Ci)2.46E-07 2.44E-05 5.05E-07 1.97E-08 7.23E-05 2.45E-21 The maximum organ (including whole body) incremental dose from material spread in 2005 was estimated to be 4.54E-04 mrem/yr. The maximum organ dose from all past spreading operations, including the material spread in 20.95, totaled 1.15E-0I mrem/yr. These calculated values are within the I mrem/yr limit applied during the period of operational control of the site. The projected hypothetical dose for the period following the loss of operational control of the site area due to all spreading operations to-date is 3.78E-0 I mrem/yr versus a 5 mrem/yr dose limit.J-1}}

1.0 INTRODUCTION

Tables 1 through 3 lists the recorded radioactive liquid and gaseous effluents and solid waste shipments for the year, with data summarized on a quarterly basis for both liquids and gases. Table 4A summarizes the estimated radiological dose commitments from all radioactive liquid and gaseous effluents released during the year 2005 in response to the ALARA objectives of 1OCFR50, Appendix I. Also included in Table 4A is the estimate of direct dose from fixed station sources along the limiting west site boundary line. Tables 5A through 6H report the cumulative joint frequency distributions of wind speed, wind direction, and atmospheric stability for the 12-month period, January to December 2005. Radioactive effluents reported in Tables 1 and 2 were used to determine the resulting doses for 2005.As required by ODCM Section 10.1, (Reference

1) dose commitments resulting from the release of radioactive materials in liquids and gases during the reporting period were estimated in accordance with the plant's "Off-Site Dose Calculation Manual" (ODCM). These dose estimates were made using a "Method II" analysis as described in the ODCM. A "Method II" analysis incorporates the methodology of Regulatory Guide 1.109 (Reference
2) and actual measured meteorological data recorded concurrently with the quarterly reporting period.As required by ODCM Section 10.1, this report shall also include an assessment of the radiation doses from radioactive effluents to member(s) of the public due to allowed recreational activities inside the site boundary during the year. During this reporting period, no recreational activity was permitted and, therefore, there is no associated dose assessment as stated in Section 3.6.Assessment of radiation doses (including direct radiation) to the likely most exposed real member(s) of the public for the calendar year for the purposes of demonstrating conformance with 40CFR1 90, "Environmental Radiation Protection Standards for Nuclear Power Operations," are also required to be included in this report if the conditions indicated in ODCM 3/4.6, "Total Dose," have been exceeded during the year. Since the conditions indicated in the action statement under ODCM 3/4.6 were not entered into during the year, no additional radiation dose assessments are required.

However, Table 4B does provide the combination of doses and dose commitments from plant effluents and direct radiation sources for the limiting member of the public off-site as a demonstration of compliance with the dose standards of 40CFRI90.All calculated dose estimates for members of the public at the site boundary or beyond for the 2005 annual reporting period are below the dose criteria of 1OCFR Part 50, Appendix I, and 40CFRI90.Appendices B through H indicate the status of reportable items per the requirements of ODCM Section 10.1.1

2.0 METEOROLOGICAL

DATA Meteorological data were collected during this reporting period from the site's 300-foot meteorological tower located approximately 2,200 feet northwest of the reactor building, and about 1,400 feet from the plant stack. The 300-foot tower is approximately the same height as the primary plant stack (94 meters) and is designed to meet the requirements of Regulatory Guide 1.23 for meteorological monitoring.

X/Q (annual or long-term average undepleted atmospheric dispersion factors) and D/Q (deposition factors for dry deposition of elemental radioiodines and other particulates) values were derived for all receptor points from the site meteorological record for each quarter using a straight-line airflow model. All dispersion factors have been calculated employing appropriate source configuration considerations, as described in Regulatory Guide 1.111 (Reference 3). A source depletion model as described in"Meteorology and Atomic Energy -1968" (Reference

4) was used to generate deposition factors, assuming a constant deposition velocity of 0.01 m/sec for all stack (elevated) releases.

Changes in terrain elevations in the site environment were also factored into the meteorological models as appropriate.

Table 4C lists the distances from the plant stack to the nearest site boundary, resident, and milk animal in each of the 16 principle compass directions as determined during the 2005 land use census. These locations were used in the calculation of atmospheric dispersion factors. The meteorological model was also executed for each calendar quarter to determine the location of the predicted maximum ground level air concentration.

These locations were included in the assessment of effluent doses along with identified points of interest from the annual land use census.2 3.0 DOSE ASSESSMENT

3.1 Doses

From Liguid Effluents ODCM 3/4.2.2 limits total body (1.5 mrem per quarter, and 3 mrem per year) and organ doses (5 mrem per quarter, and 10 mrem per year) from liquid effluents to a member of the public to those specified in 1OCFR Part 50, Appendix I. By implementing the requirements of 1OCFR Part 50, Appendix I, ODCM 3/4.2.2 assures that the release of radioactive material in liquid effluents will be kept "as low as is reasonably achievable." For periods in which liquid waste discharges actually occur, the exposure pathways that could exist are fish, direct exposure from river shoreline sedimentation, milk and meat via animal ingestion of the Connecticut River water, and meat, milk and vegetable pathways via crop irrigation with water withdrawn from the Connecticut River. Ingestion pathways of drinking water and aquatic invertebrate do not exist down river of the Vermont Yankee plant.There were no recorded liquid radwaste discharges during the report period, and therefore, no dose impact.3.2 Doses From Noble Gases ODCM 3/4.3.2 limits the gamma air dose (5 mrad per quarter, and 10 mrad per year) and beta air (10 mrad per quarter, and 20 mrad per year) dose from noble gases released in gaseous effluents from the site to areas at and beyond the site boundary to those specified in 1OCFR Part 50, Appendix I. By implementing the requirements of 10CFR Part 50, Appendix I, ODCM 3/4.3.2 assures that the releases of radioactive noble gases in gaseous effluents will be kept "as low as is reasonably achievable." Dose estimates due to the release of noble gases to the atmosphere are typically calculated at the site boundary, nearest resident in each of the sixteen principal compass directions, the point of highest off-site ground level air concentration of radioactive materials, and for each of the milk animal locations located within five miles of the plant. For 2005, noble gases were detected in effluents released from the plant stack in the first and third quarters.The maximum estimated quarterly and annual air doses due to noble gases at any of the off-site locations are reported in Table 4A. These estimated air doses are well below the 1OCFR Part 50, Appendix I dose criteria of ODCM 3/4.3.2. Table 4B list the annual dose impact from gaseous effluents (including noble gases) at the overall highest impacted resident location after consideration of all exposure categories (i.e., liquid, gas and fixed radiation sources).

Table 4B provides an estimation of the total annual dose impact associated with the highest exposed member of the public for demonstration of compliance to the dose standard contained in 40CFR Part 190 for the uranium fuel cycle.3

3.3 Doses

From Iodine-131, Iodine-133.

Tritium. and Radionuclides in Particulate Form With Half-Lives Greater Than 8 Days ODCM 3/4.3.3 limits the organ dose to a member of the public from iodine-131, iodine-133, tritium and radionuclides in particulate form with half-lives greater than 8 days (hereafter called iodines and particulates) in gaseous effluents released from the site to areas at and beyond the site boundary to those specified in IOCFR Part 50, Appendix I (7.5 mrem per quarter, and 15 mrem per year). By implementing the requirements of IOCFR Part 50, Appendix I, ODCM 3/4.3.3 assures that the releases of iodines and particulates in gaseous effluents will be kept "as low as is reasonably achievable." Exposure pathways that could exist as a result of the release of iodines and particulates to the atmosphere include external irradiation from activity deposited onto the ground surface, inhalation, and ingestion of vegetables, meat and milk. Dose estimates were made at the site boundary and nearest resident in each of the sixteen principal compass directions, as well as all milk animal locations within five miles of the plant. The nearest resident and milk animals in each sector were identified by the most recent Annual Land Use Census as required by ODCM 3/4.5.2 (see Table 4C). Conservatively, a vegetable garden was assumed to exist at each milk animal and nearest resident location.

Furthermore, the meat pathway was assumed to exist at each milk cow location since this data category is not part of the annual land use census. Doses were also calculated at the point of maximum ground level air concentration of radioactive materials in gaseous effluents and included the assumption that the inhalation, vegetable garden, and ground plane exposure pathways exist for an individual with a 100 percent occupancy factor.It is assumed that milk and meat animals are free to graze on open pasture during the second and third quarters with no supplemental feeding. This assumption is conservative since most of the milk animals inventoried in the site vicinity are fed stored feed throughout the entire year with only limited grazing allowed during the growing season. It has also been assumed that only 50 percent of the iodine deposited from gaseous effluent is in elemental form (12) and is available for uptake (see p. 6, Reference 2). During the non-growing season (first and fourth quarters), the milk animals are assumed to receive only stored feed. During the growing season (second and third quarters), all animal feed is assumed to be derived from fresh pasture. Usage factors for gaseous effluents are listed by age group and pathway in Table 4D. Table 4E provides other dose model parameter assumptions used in the dose assessments.

The resultant organ doses were determined after adding the contributions from all pathways at each location.

Doses were calculated for the whole body, GI-tract, bone, liver, kidney, thyroid, lung and skin for adults, teenagers, children and infants. The maximum estiniated quarterly and annual organ doses to any age group due to iodines and particulates at any of the off-site receptor locations are reported in Table 4A. These estimated organ doses are well below the 1OCFR Part 50, Appendix I dose criteria of ODCM 3/4.3.3. Table 4B provides an estimation of the total annual dose impact (including contributions from iodine and particulates) associated with the highest exposed member of the public for demonstration of compliance to the dose standard contained in 40CFR Part 190 for the uranium fuel cycle.4

3.4 Whole

Body Doses in Unrestricted Areas From Direct Radiation The major source of dose in unrestricted areas occurs at the west site boundary, and mainly consisting of direct and skyshine radiation from N-16 decay in the Turbine Building steam cycle during power operations.

Because of the orientation of the Turbine Building on the site, and the shielding effects of the adjacent Reactor Building, only the seven westerly sectors (SSW to NNW)see any significant direct radiation.

A correlation method was derived, based directly on site boundary exposure rate and in-plant Main Steam Line Radiation Monitor measurements, that allows changes in the N-16 carryover in the main steam flow to be directly related to changes in the site boundary dose. This correlation is documented in section 6.11.1 (Equation 6-27a) of the ODCM. This method was used to calculate direct dose at the maximum site boundary location from radiation sources in the steam cycle.The other fixed sources of direct and scatter radiation to the site boundary are from low level radioactive waste stored in the North Warehouse, the Low Level Waste Storage Pad Facility, and old turbine rotors and casings in the Turbine Storage Facility.

The annual dose is based on dose rate measurements in these three storage facilities and determined at the same most restrictive site boundary dose location as that for N- 16 shine from the Turbine Building.The estimated direct radiation dose from all major sources combined for the most limiting site boundary location is listed in Table 4A. These site boundary doses assume a 100 percent occupancy factor, and take no credit for the shielding effect of any residential structure.

Table 4B lists the combination of direct radiation and effluent release doses at the limiting nearest residence for the purpose of demonstrating compliance with the dose standards contained in 40CFR Part 190. For direct radiation, no credit for actual occupancy time is taken (i.e., occupancy is equal to 100%).For 2005, the annual dose limit for the nearest real resident from all station sources (effluents plus fixed radiation sources) was below the 25 nirem total body and organ limit (75 mrem thyroid) of 40 CFR 190.3.5 Doses From On-Site Disposal of Septic Waste. Cooling Tower Silt and Soil Off-Site Dose Calculation Manual, Appendices B, F and I, require that all applications of septage, cooling tower silt and sand/soil within the approved designated disposal areas be limited to ensure the dose to a maximally exposed individual during the period of Vermont Yankee site control be maintained at less than 1 mrem/year to the whole body and any organ. After the period associated with Entergy-Vermont Yankee operational control, the dose to the inadvertent intruder is to be maintained at less than 5 mnrem/year.

The projected dose from on-site disposals of septic waste, cooling tower silt and sand/soil mixes is given in Appendix J of this report.The dose limits applicable for the on-site spreading of materials were met for the single disposal (septic waste) in 2005 and in combination with all past spreadings.

5 3.6 On-Site Recreational Activities During 2005, no access for employees, their families and guests to the boat launching ramp located on-site just north of the intake structure was permitted.

As such, no recreational activities were permitted on-site during the report period and, therefore, no associated dose impact to members of the public.6 REFERENCES

a. Average gamma energy: Not Applicable
b. Average beta energy: Not Applicable
4. MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY Provided below are the methods used to measure or approximate the total radioactivity in effluents and the methods used to determine radionuclide composition.
a. Fission and Activation Gases Continuous stack monitors monitor the gross Noble Gas radioactivity released from the plant stack. Because release rates are normally below the detection limit of these monitors, periodic grab samples are taken and analyzed for the gaseous isotopes present. These are used to calculate the individual isotopic releases indicated in Table IB and the totals of Table IA. The error involved in these steps may be approximately

+/-23 percent.b. lodines Continuous isokinetic samples are drawn from the plant stack through a particulate filter and charcoal cartridge.

The filters and cartridges are normally removed weekly and are analyzed for Iodine-131, 132, 133, 134, and 135. The error involved in these steps may be approximately

+/-18 percent.A-2

c. Particulates The particulate filters described in b. above are also counted for particulate radioactivity.

The error involved in this sample is also approximately

+/-18 percent.d. Tritium ODCM Table 4.3.1 requires as a minimum that grab samples from the plant stack be taken monthly and analyzed for tritium. The stack tritium collection has been upgraded with silica gel columns and continuous sampling of stack effluents.

The error involved in this sample is approximately

+/- 10 percent.e. Waste Oil Prior to issuing the permit to burn a drum of radioactively contaminated waste oil, one liter of the oil is analyzed by gamma spectroscopy to determine concentrations of radionuclides that meet or exceed the LLD for all of the liquid phase radionuclides listed in ODCM Table 4.2.1.Monthly, samples from drums that were issued bum permits are sent to the contracted laboratory for compositing and analysis.

The lab analyzes for tritium, alpha, Fe-55, Sr-89, and Sr-90 on the composite sample.The error involved in this sample is approximately

+/-15 percent.f. Liquid Effluents If radioactive liquid effluents are to be released from the facility, they are continuously monitored.

Measurements are also required on a representative sample of each batch of radioactive liquid effluents released.

For each batch, station records are retained of the total activity (mCi) released, concentration (IiCi/ml) of gross radioactivity, volume (liters), and approximate total quantity of water (liters) used to dilute the liquid effluent prior to release to the Connecticut River.Each batch of radioactive liquid effluents to be released is analyzed for gross gamma and gamma isotopic radioactivity.

A monthly proportional composite sample, comprising an aliquot of each batch released during a month, is analyzed for tritium and gross alpha radioactivity.

A quarterly proportional composite sample, comprising an aliquot of each batch released during a quarter, is analyzed for Sr-89, Sr-90, and Fe-55.A-3

5. BATCH RELEASES a. Liquid There were no routine liquid batch releases during the reporting period.b. Gaseous Waste oil was burned during the first quarter and was considered to be a continuous release.The gaseous releases from burning waste oil are treated as either batch or continuous releases based on the total hours of burning in a calendar quarter.All other atmospheric discharges were recorded as continuous elevated releases from the main plant stack.6. ABNORMAL RELEASES a. Liquid There were no non-routine liquid releases during the reporting period.b. Gaseous There were no non-routine gaseous releases (measured) during the reporting period.A-4 APPENDIX B LIQUID HOLDUP TANKS Requirement Response: Technical Specification 3.8.D.I limits the quantity of radioactive material contained in any outside tank. With the quantity of radioactive material in any outside tank exceeding the limits of Technical Specification 3.8.D.1, a description of the events leading to this condition is required in the next annual Radioactive Effluent Release Report per ODCM Section 10.1.The limits of Technical Specification 3.8.D. 1 were not exceeded during this reporting period.B-I APPENDIX C RADIOACTIVE LIQUID EFFLUENT MONITORING INSTRUMENTATION Requirement:

Response: Radioactive liquid effluent monitoring instrumentation channels are required to be operable in accordance with ODCM Table 3.1.1. If an inoperable radioactive liquid effluent monitoring instrument is not returned to operable status prior to a release pursuant to Note 4 of Table 3.1.1, an explanation in the next annual Radioactive Effluent Release Report of the reason(s) for delay in correcting the inoperability are required per ODCM Section 10.1.Since the requirements of ODCM Table 3.1.1 governing the operability of radioactive liquid effluent monitoring instrumentation were met for this reporting period, no response is required.C-1 APPENDIX D RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION Requirement:

Response: Radioactive gaseous effluent monitoring instrumentation channels are required to be operable in accordance with ODCM Table 3.1.2. If inoperable gaseous effluent monitoring instrumentation is not returned to operable status within 30 days pursuant to Note 5 of Table 3.1.2, an explanation in the next annual Radioactive Effluent Release Report of the reason(s) for the delay in correcting the inoperability is required per ODCM Section 10.1.Since the requirements of ODCM Table 3.1.2 governing the operability of radioactive gaseous effluent monitoring instrumentation were met for this reporting period, no response is required.D-1 APPENDIX E RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Requirement:

Response: The radiological environmental monitoring program is conducted in accordance with ODCM Control 3/4.5.1. With milk samples no longer available from one or more of the sample locations required by ODCM Table 3.5.1, ODCM 10.1 requires the following to be included in the next annual Radioactive Effluent Release Report: (1) identify the cause(s) of the sample(s)no longer being available, (2) identify the new location(s) for obtaining available replacement samples and (3) include revised ODCM figure(s) and table(s) reflecting the new location(s).

No changes were needed in the milk sampling locations as specified in ODCM Table 3.5.1 and implemented in ODCM Table 7.1 during the reporting year.E-1 APPENDIX F LAND USE CENSUS Requirement:

Response: A land use census is conducted in accordance with ODCM Control 3/4.5.2.With a land use census identifying a location(s) that yields at least a 20 percent greater dose or dose commitment than the values currently being calculated pursuant to ODCM Control 4.3.3, the new location(s) must be identified in the next Annual Radioactive Effluent Release Report.The Land Use Census was completed during the third quarter of 2005. No significant land use changes from the previous year's census were identified.

As a result, no locations were identified which yielded a 20 percent greater dose or dose commitment than the values currently being calculated pursuant to ODCM Control 4.3.3.F-1 APPENDIX G PROCESS CONTROL PROGRAM Requirement:

Response: ODCM Section i 0. 1 requires that licensee initiated changes to the Process Control Program (PCP) be submitted to the Commission in the annual Radioactive Effluent Release Report for the period in which the change(s) was made.There were no changes made to the Process Control Program during this reporting period.G-1 APPENDIX H OFF-SITE DOSE CALCULATION MANUAL Requirement:

Response: Technical Specification 6.7.B. 1 requires that licensee initiated changes to the Off-Site Dose Calculation Manual (ODCM) be submitted to the Commission in the annual Radioactive Effluent Release Report for the period in which the change(s) was made effective.

There were no changes made to the ODCM during this reporting period.H-1 APPENDIX I RADIOACTIVE LIQUID, GASEOUS, AND SOLID WASTE TREATMENT SYSTEMS Requirement:

Response: ODCM Section 10.4 requires that licensee initiated major changes to the radioactive waste systems (liquid, gaseous, and solid) be reported to the Commission in the annual Radioactive Effluent Release Report for the period in which the evaluation was reviewed by the Plant Operation Review Committee.

There were no licensee-initiated major changes to the radioactive waste systems during this reporting period.I-1 APPENDIX J ON-SITE DISPOSAL OF SEPTIC/SILT/SOIL WASTE Requirement:

Response: Off-Site Dose Calculation Manual, Appendices B, F and I require that the dose impact due to on-site disposal of septic waste, cooling tower silt and sand/soil type materials during the reporting year and from previous years be reported to the Nuclear Regulatory Commission in the annual Radioactive Effluent Report if disposals occur during the reporting year. Entergy -Vermont Yankee will report in the Annual Radioactive Effluent Release Report a list of the radionuclides present and the total radioactivity associated with the on-site disposal activities on the Vermont Yankee site.There was one on-site disposal of septic waste during the reporting year. The total volume of the septic waste spread in 2005 was 11,000 gallons. The total activity spread on the 1.9 acres (southern) on-site disposal field from 2005 spreading and from previous years was as follows: Activity Spread in 2005 Nuclide Mn-54 Co-60 Zn-65 Cs-134 Cs-137 Ce-141 (Ci)1.33E-07 3.80E-08 3.80E-08 1.90E-08 3.80E-08 0.OOE+00 Activity from 2005, plus Activity from All Past Disposals Decayed to 07/26/2005 (Ci)2.46E-07 2.44E-05 5.05E-07 1.97E-08 7.23E-05 2.45E-21 The maximum organ (including whole body) incremental dose from material spread in 2005 was estimated to be 4.54E-04 mrem/yr. The maximum organ dose from all past spreading operations, including the material spread in 20.95, totaled 1.15E-0I mrem/yr. These calculated values are within the I mrem/yr limit applied during the period of operational control of the site. The projected hypothetical dose for the period following the loss of operational control of the site area due to all spreading operations to-date is 3.78E-0 I mrem/yr versus a 5 mrem/yr dose limit.J-1
