1.0 INTRODUCTION
Tables 1 through 3 list the recorded radioactive liquid and gaseous ; eff.luents and solid waste for the second six months of the year, with data ; summarized on a quarterly basis for both liquids and gases. Table 4 summarizes the estimated radiological dose commitments from all radioactive , liquid and gaseous effluents released during the year 1992, including direct l dose from fixed station sources. Tables SA through 6H report the cumulative { joint frequency distributions of wind speed, wind direction, and atmospheric stability for the 12-month period. January to December 1992. Radioactive j effluents reported in the Semiannual Effluent Report covering the first six ; months of the year were used to determine the resulting doses for the first l half of 1992. ! [ As required by Technical Specification 6.7.C.1 dose commitments ! resulting from the release of radioactive materials'in liquids and gases were i estimated in accordance with the " Vermont Yankee Nuclear Power Station j Off-Site Dose Calculation Manual" (0DCM). These dose estimates were made ! using a " Method II* analysis as described in the ODCM. A
- Method II" analysis h incorporates the methodology of Regulatory Guide 1.109 (Reference 3) and
, actual measured meteorological data recorded during the reporting period. f As required by. Technical Specification 6.7.C.1.b. this report shall also include an assessment of the radiation doses from radioactive effluents.to i member (s) of the public due to allowed recreational activities inside the site l boundary during the year. However, for this reporting period no recreational f activities inside the. site boundary were permitted, and, as a result, no dose ! assessments are required. ! 1 1 Assessment of radiation doses (including direct radiation) to the likely [ most exposed real member (s) of the public for the calendar year for the l purposes of demonstrating conformance with 40CFR190, " Environmental Radiation ~; Protection Standards for Nuclear Power Operations," are also required to be i included in this report'if the conditions indicated in Technical l Specification 3.8.M.1. " Total Dose,* have been exceeded during the year. l Since the conditions indicated in the action statement under Technical l Specification 3.8 M.2 were not entered into during the year, no additional' I radiation dose assessments are required.

i j 2,0 METEOROLOGICAL DATA ~ l Meteorological data was collected during this re70rting period from the ' site's 300-foot met tower located approximately 2.200 f tet northwest of the J reactor building, and about 1.400 feet from the plant s;ack. The 300-foot- ; tower is approximately the same height as the primary plant stack (94 meters) l and is designed to meet the requirements of Regulatory Guide 1.23 for- i meteorological monitoring. .i X/0 and D/0 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 1). A source depletion model as described in " Meteorology and '! Atomic Energy - 1968* (Reference 2) was used to generate deposition factors, assuming a constant deposition velocity of 0.01 m/sec for all stack (elevated) releases. Turbine hall roof vents are considered as ground level release ' points with relative deposition rates determined from Regulatory Guide 1.111. Changes in terrain elevations in the site environment were also factored into -j the meteorological models as appropriate. : P l t i [ i I i nua l l

a 3.0 DOSE ASSESSMENT i 3.1 Doses From Liouid Effluents , 1 Technical Specification 3.8.B.1 limits total body (1.5 mrem per quarter, j and 3 mrem per year) and organ doses (5 mrem per quarter, and 10 mrem per ; yeari from liquid effluents to a member of the public to those specified in i 10CFR Part 50, Appendix 1. By implementing the r equiremeats of 10CFR Part 50, i Appendix 1. Technical Specification 3.8.B.1 assures that the release of I radioactive material in liquid effluents will be kept "as low as is reasonably l achievable." ) i 1 Exposure pathways that could exist as a result of liquid effluents are l fish, direct exposure from river shoreline sedimentation, milk and meat via animal ingestion of the Connecticut River water. and meat, milk and vegetable, j pathways via crop irrigation with water withdrawn from the Connecticut River, , The drinking water and aquatic invertebrate pathways do not exist downriver of f the Vermont plant at Vernon. l 1 The dose analysis for the liquid pathways, given above, assumes a ; dilution based on a minimum regulated river flow of 1250 cfs at the Vernon Dam ! 1 just below the plant discharge outfall. This results.in conservative dose estimates ' rom the liquid effluents. f The resultant whole body and organ doses from liquid effluents were j determined by summing the contributions from all pathways at each location. j The whole body and organ. doses to a member of the public from liquid effluents ) are given in Table 4. The estimated quarterly and annual doses due to liquid
]
efficents are well below the 10CFR Part 50. Appendix 1 dose criteria of ; Technic;' Specification 3.8.B.1. I i 3.2 Doses From Noble Gases l Technical Specification 3.8.F.1 limits the gamma air dose (5 mrad per l quarter, and 10 mrad per year) and beta air (10 mrad per quarter. and 20 mrad I per year) dose from noble g3ses released in gaseous effluents from the site to areas at and beyond the site coundary to those specified in 10CFR Part 50, Appendix 1. By implementing the requirements of 10CFR Part 50. Appendix 1, Technical Specification 3.8.F.1 assures that the releases of radioactive noble gases in gaseous effluents will be kept *as low as is reasonably achievable." 4 nrac ! i

Dose estimates due to the' release.of noble gases to the atmosphere are typically calculated at the site boundary, and nearest resident in each of the I sixteen principle compass directions, as well-~as 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. j i 3.3 Doses From Iodine-131. Todine-133. Tritium, and Radionuclides in ! Particulate Form With Half-Lives Greater Than 8 Days ; Technical Specification 3.8.G.1 limits the organ dose to a member of the : public from iodine-131, iodine-133, tritium and radionuclides in particulate 'l form with half-lives greater than 8 days (hereafter called iodines and -- particulates) in gaseous effluents released from the site to areas at and j beyond the site boundary to those specified in 10CFR Part 50, Appendix I l (7.5 mrem per quarter, and 15 mrem per year). By implementing the requirements of 10CFR Part 50 Appendix 1. Technical Specification 3.8.G.1 ]* assures that the releases of. iodines and particulates in gaseous effluents i will be kept "as low as is reasonably achievable." I
.I' 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 j resident in each of the sixteen principle ccmpass directions, as well as all ! milk animal locations within five miles of the plant. The nearest resident l and milk animals in each sector were identified by the most'recent Annual Land '! Use Census as required by Technical Specification 3.9.D.1. Conservatively, a j vegetable garden was assumed to exist at each milk animal and nearest resident I location. Furthermore, the meat pathway was assumed to exist at each milk animal location. Doses were also calculated at the point of maximum ground I 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 .I 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 j 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 (1 2
) and is available for uptake (see p. 26. Reference 3). !

During the first and fourth quarters, the milk animals are assumed to receive only stored feed. 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 estimated 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 4. These estimated organ doses are well below the 10CFR Part 50, Appendix I dose criteria of Technical Specification 3.8.G.I. 3.4 Whole-Bodv Doses in Unrestricted Areas From Direct Radiation The major source of dose, consisting of direct radiation and skyshine, from the station is due to N-16 decay in the turtine building. 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. High Pressure Ionization Chamber (HP!C) measurements have been made in the plant area in order to estimate the direct radiation from the station. The chamber was located at a point along the west site boundary which-has been determined to receive the maximum direct radiation from the plant. Using j measurements of dose rate made while the plant operated at different power l levels, from shutdown to 100 percent, the total integrated dose from direct radiation over each three month period was determined by considering the quarterly gross megawatts generated. Field measurements of exposure, in units of Roentgen, were modified by multiplying by 0.6 to obtain whole-body dose equivalents, in units of rem, in accordance with recommendations of HASL Report 305 (Reference 4) for radiation fields resulting from N-16 photons. The other sources of dose, including direct radiation and skyshine, to the site boundary are from low level radioactive waste stored in the north warehouse and the low level waste storage pad f acility. The annual dose is based on dose rate measurements in these two storage facilities and determined at the same most restrictive site boundary dose location as that for N-16 shine from the Turbine Building. I The estimated direct radiation dose from all major sources combined for the most limiting site boundary location is listed on Table 4 for each uruo _ _ _ _ _ _ _ _ _ _
4 L quarter. These site boundary doses assume a 100 percent occupancy-factor, and take no credit for the shielding effect of any structure. 3.5 Doses From On-Site Disposal of Septic Waste , Off-Site Dose Calculational Manual Appendix B, requires that all-applications of septage within the approved designated disposal areas be .; limited to ensure the dose to a maximal.ly-exposed individual be maintained at- ! less than 1 mrem / year to the whole body and any organ, and the dose to. the t inadvertent intruder be maintained at less than 5 mrem / year. The projected ; dose from on-site disposals of septic waste is given in-Appendix J. ' i I i k 7 l t i l i nuso i I l u .- , . , - . . . , . .e. -

- a. Fission and Activation Gases !
Continuous stack monitors monitor gross Noble Gas radioactivity j released from the plant stack. Total Noble Gas release rates are calculated using this monitor. To determine the isotopic breakdown ; of the release, samples are taken of the Steam Jet Air Ejector, j which is the source gas for the releases. These samples.are ; analyzed by gamma spectroscopy to determine the isotopic-composition. The isotopic composition is then proportioned to the j gross releases determined from the stack monitor to quantify the l individual isotopic releases. These are indicated in Table IB and ; the totals of Table 1A. [ Beginning in the fourth quarter of 1991, grab samples were obtained j from the Turbine Building roof vents. In July, only Xe-135m was l detected in the samples. The remainder of the gases indicated were l calculated by ratioing the indicated Xe-135m to the other gases ! using the Steam Jet Air Ejector samples. In September, only Xe-135 ; was detected in the samples. The remainder of the gases indicated were calculated by ratioing the indicated Xe-135 to the other gases j using the Steam Jet Air Ejector samples. For the remainder of this reporting period, only Cs-138 was detected in the samples. The l remainder of the gases indicated were calculated by assuming Cs-138 solely from the decay of Xe-138 and then ratioing Xe-138 to the other gases using the Steam det Air Ejector samples. These results are indicated in Table 1C and the totals of Table 1A. l f The error involved in these steps may be approximately 1100 percent. I . i

Continuous isokinetic samples are drawn from the plant stack through-a particulate filter and charcoal cartridge.

- c. Particulates The particulate filters described in b. above- are also counted for particulate radioactivity. The error involved in this sample is also approximately 150 percent.
- d. Licuid Effluents Radioactive liquid effluents released from the f acility 'are continuously monitored. Measurements are also made 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 (uCi/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 effluent releases 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.
