A h HNP ANNUAL REPORT 1.1 RACIOIOGICAL MONI'IORING 1.1 Introduction

%e objectives of the Radiological Enviromental Monitoring Progra are to ascertain the levels of radiation and concentrations of radioactivity in the

, enviroment which are due to plant operations and to evaluate the impact to the enviroment fra these radiological levels. Assurance is provided in achieving these objectives by following the progr m's rquirenents as described in Section 3.2 of the Enviromental Technical Specifications (ETS).

Provided herein are the progr m 's results for calendar year 1983 which include an assessment of the radiological impact upon the enviroment, as well as reports en various related activities.

A stmnary, interpretation and evaluation of the analytical results obtained from the smples utilized for the enviromental monitoring of discharges of radioactive materials to the atmosphere, river and ground are provided, as appropriate, in Sections 1.2,1.3 and 1.4, respectively. We data on smples required by the ETS are tabulated by station or group of stations. As practical, each tabulation consists of: the maximm, minimum and average values of the radiological level; the number of saples (n); and the standard l deviation (s). Nminally, sumaries are provided for the control and

indicator stations on an annual basis; they may also be provided for other t/ periods of exposure as feasible. 'Ihe calculated minimte detectable difference (MDD) at the 99% confidence level between these two groups is provided for cmparison with the difference in their average values, Li-Lc.

Deviations are permitted from the sapling schedule rquired by Table 3.2-1 of the EIS if specimens are unobtainable due to hazardous conditions, seasonable unavailability, malfunction of autmatic sapling quipment or other legitimate reasons. Any deviations frm the rquired smpling schedule are included in the discussions for each particular type smple.

In Section 1.5, the results of the EPA Crosscheck Progrm are provided. In Section 1.6, the chief conclusions are presented.

1.2 Discharges 'Ib %e Atmosphere ne media or pathways s a pled to monitor discharges to the atmosphere consisted of: airborne dust, airborne iodine, external radiation, milk and grass. Airborne dust and iodine were collected at air monitoring stations.

In accordance with the ETS, thermoluminescent dosimeters (TIDs) for measuring external radiation were placed at each of the air stations and at three other locations as shown below. Starting with the 1st quarter of 1980, additional TIDs were placed ~ in the site environs to conform with Revision 1 of the Technical Position of the Radiation Assessment Branch of the NRC, dated Novenber 1979. The locations of these new TLDs are described in Section 1.2.3. 'Ite locations of the milk smpling stations are provided in Section 1.2.4. Grass smples were collected frm plots maintained at Air Stations 1-1 L

i 5, 17 and 21. The sector location and distance as reckoned frm the main stack to each of the air stations and to each of the TLD stations required by O the ETS are as follows:

Air Stations No. 1 State Prison DE 11.2 miles No. 5 Baxley S 10.0 miles No. 9 Dead River Road E 1.8 miles No. 15 Roadside Park WNN 0.8 miles No. 17 Site Boundary SE 1.2 miles No. 21 Site Boundary WSW l.0 miles TLD Stations (same as air stations plus)

No. 119 East Boundary ESE 1.1 miles No. 126 South Boundary S 0.9 miles No. 133 West Boundary W l.1 miles Stations 1 and 5 are the control stations; the other stations are indicator stations.

All required laboratory analyses of the samples collected to monitor discharges to the atmosphere are contracted to Teledyne Isotopes, Inc. of Westwood, New Jersey except for: the gross beta counting of airborne particulates which is perfomed by the plant; the reading of the TLDs which is O

V done by Teledyne Isotopes Midwest Laboratory at Northbrook, Illinois; and the gama scan of grass which is provided by the Center for Applied Isotope Studies at the University of Georgia in Athens, Georgia.

During the first half of 1983, the TLDs were read by Hazleton 'Enviromental Sciences, Inc. (HES) of Northbrook, Illinois. Effective July 1, 1983, Teledyne Isotopes acquired all assets and business of HES and thenceforth the Nuclear Science Department of HES began operation under the nane of Teledyne Isotopes Midwest Laboratory.

1.2.1 Airborne Dust The annual stunary of the gross beta activities for the airborne dust samples which were collected weekly is presented in Table 1.2-1. %ere is no discernable difference between the average activity of the control stations and of the indicator stations as (Li -Ic) is 1 fCi/m3 and this is less than the MDD of 7 fCi/m3 .

We average grogs beta activity for all stations during 1983 was 31 fCi/m3; it was 33 fCi/m during 1982. Going back to 1976 for several years, it was 4 to 8 times greater than that for 1983. Those high values were shown to be the result of fallout frm the ntrnerous nuclear weapons tests conducted on mainland China fra 1976 through 1980.

I Due to mechanical failures, valid data were unavailable on one occasion at

~

O- each of the stations except for Station 9 where valid data were unavailable on three occasions. Of these eight failures, three were due to the failure of the air .pmp itself, two were due to a blown fuse, and three were due to

deaged air dust filters -- one of the filters was partially eaten by bees, E the other two were broken in handling.

We activities of specific radionuclides detected in quarterly cmposites of

airborne dust filters by gama spectral analyses are stamarized in Table 1.2-2 for- the entire year. Only three different radionuclides were detected of which only one, Cs-137, is mamade; the Cs-137 was detected in only one l smple. Several years ago during the height of the impact of the weapons tests, nine different mamade radionuclides were detected annually from a few j hundred positive results.

%e Cs-137 was found at a level of 0.7 fCiA3 . Typically it has been found in one to two dozen smples each year at levels a few times greater. The maximpalthough Iower Limit of Detection -(LLD)3 allowed by Table 3.2-2 of the ETS is 10 fCiA an LID of 0.3 fCiA is generally achieved;3the Reporting i Level (RL) required by Table 3.2-3 of the ETS is 20,000 fCiA . he RL for a given radionuclide in a given medim is the concentration for which it has been conservatively estimated to be equivalent to the appropriate annual dose

-limit of Appendix I to 10 CER 50 for an individual when so exposed for one

-year.

%e levels and frequencies of occurrences of the two naturally occurring radionuclides, Be-7 and K-40, are typical of those seen in previous years, t

O 1.2.2 Airborne Iodine

ne charcoal' cartridge used for adsorbing iodine fra the atmosphere were i collected weekly and analyzed for I-131 by Ge(Li) spectroscopy. I-131 was not detected in any of the samples during 1983.

I 2e only positive measurement 'of I-131 attributable to plant releases during nearly 10 years of operations occurred for the smple collected on April 26, 1982 at Station 15 which is located about 0.g miles _inside the site boundary.

%is saple showed a level of 37.2 fCIA . %e maximm allowed LID is 70 fCiA3; the LLDs achieved during 1982 never exceeded 40 fCiA3 ,

During -1976,1977 and 1978 detectable levels of I-131 were found for periods of a few weeks after the arrival of the cloud fra eph of the nuclear weapons tests. %e highest level eva found was 217 fCiA in 1977. De RL is 900 fCLA3 . .

1.2.3 hermolminescent Dosimeters V ne nminal location of each of the '"LDs by sector and by distance frm the main stack in miles is provided in Table 1.2-3. 'Iwo badges are placed at each station; each badge contain.e's five LiF chips. At the beginning of 1980, an attspt was made to establish two TLD stations in each sector (in accordance with Revision 1 to the Technical Position of the Radiological Assesment Branch of the NRC, dated Novenber 1979), one near the site boundary and the other at a distance of about four or five miles. Suitable locations were not found in the East Sector. In addition to the locations for these two rings of TLD stations, the table provides for the locations of the control stations and the stations of special interest.

We annual stmnary of the on-station doses acquired by the TLDs which are required by the ETS is presented in Table 1.2-4. nere is no discernable difference between the average values at the indicator and control stations.

%e annual stenary of the on-station doses acquired at the site boundary and at 4-5 miles is presented in Table 1.2-5. Again, there is no discernable difference between the average values at the site boundary and the 4-5 mile ring. The on-station quarterly doses acquired by the TLDs placed at Station 31 (Tombs Central School) ranged frm 9.1 to 12.5 mren with 10.1 mre as an average.

TIDs are frequentl; lost due to theft and are frequently d maged by vandalism. At monthly intervals the TLD stations are checked for missing or daaged badges; replacenents are provided as needed. In the 4th quarter p) 1 V

Stations 13,14 and 27, both badges were missing at the end of the quarter, no-data were obtained at these locations for the 4th quarter. A total of at so 14 badges from 8 different stations were found to be missing during the year. 'Ib diminish the frequency of missing or dmaged badges, TLDs are placed in less conspicuous places wherever this is practical.

1.2.4 Milk Milk samples are collected biweekly as available at three stations. Gama isotopic and I-131 analyses are performed on each saple. @is is the sixth consecutive year for performing the gama scans.

%e locations of the milk smpling stations and the ntrnber of smples analyzed were as follows:

( Station Sector Distance n_o i

! State Prison ENE -

10.8 miles 25 l Johnson Brothers SW 9.1 miles 25 l Willimsons NNE 3.2 miles 17 i

ne smples collected at all stations on January 3 and the smples collected at the State Prison and Johnson Brothers on June 20 were lost in transit to the contract lab. The cow at Willimsons becae pregnant; her milk production diminished; subsequently, no milk saples were available after August 15 L

except for the one collected on September 26.

%e State Prison is the control station and Willimsons is the indicator station. Johnson Brothers Dairy is a bit too far away to be considered as an indicator station; however, it is the closest location in the sector into

! which the wind blows most fraluently.

l l

Bere were no positive indications of I-131 in any of the milk samples during the year. %is is the third straight year that this has occurred. Previous

( levels ranged frm 0.095 to 88 pCi/1. All significant readings were generally

! . attributed to the weapons tests. %e LLD required by the ETS is 0.8 pCi/1; the RL is 3 pCi/1.

P l As usual, the gama scans showed naturally occurring K-40 present in each

! smple at levels which varied between 671 and 1540 pCi/1. Rese levels are slightly lower than those found in previous years.

%e gana scans also showed positive indications of the fission product Cs-137

- in about a. quarter of the samples collected. %e levels were found to be about the see as those found previously. %e results in pCi/l for each station are sumarized as follows

~ chemical separation techoklue; the levels ranged fra 2 to 60 pCi/l with an average'value of 19.3 pCi/1. All of these positive indications of Cs-137 in

. milk, those during preoperations, 'as well as those during operations, are attributed to the weapons tests. %e quantity of Cs-137 released fre operation of the plant would have to be increased by a' few orders of magnitude before it could be detected in the milk sanples.

We ETS require that a survey be conducted annually to detemine the location

~

of all milk ; animals within 3 miles of the plant stack in each of the 16 -

azimuthal sectors. Ebr any of the 16 sectors in which milk animals are not l ' found within 3 miles, the annual survey is expanded to locate. the nearest' milk L animal'within S miles in that sector. ' A milk snimal is a cow or goat which is

producing milk for haan consmption. On May 16 and- 17, the milk animal survey was conducted. The' only milk producing animal found was the cow at Williansons which is presently being sapled.

1.2.5 Grass a Gama isotopic analyses were performed on each of the grass smples collected monthly from the three sapling stations. Positive indication for several radionuclides were determined. %ese have been separated into four groups as follows:

(1) Be-7 and K-40; (2) Cs-134 and Cs-137; (3) Pb-214, Bi-214; and Ra-228; and (4) T1-208, Pb-212, Bi-212, and Ac-228 Only in the second group are there manmade radionuclides. Each of the radionuclides detected except for Be-7, Cs-134 and Bi-212 was found in soil smples taken at each of these plots several years ago. An annual sumary of the activities of these radionuclides is provided in Table 1.2-6. It is seen that there are no discernable differences between the average values of the indicator stations and the control station.

As usual, Be-7 and K-40 were detected in every smple. The levels are on the sme order of magnitude as those found previously. %e overall average for Be-7 is about 50% higher than that found last year while that for K-40 is about 40% lower.

Usually Cs-137 is found in about 70% of the smples but this year it was found l in all but one saple. %e levels, however, were well within the range of those found in previous years.

p'V The 17 pCi/kg wet value for the single reading of Cs-134 may be cmpared with the 1981 value of 15 pCi/kg wet which is the only positive reading obtained previously. The E'IS requirments for LID and RL are 80 and 1000 pCi/kg wet, respectively. During the year the LLD ranged frm 10 to 41 pCi/kg wet.

Each of the radionuclides in the third and fourth groups is a primordial nuclide. %e radionuclides in the third group are from the Uranium Series.

%ose in the fourth group are frce the %orim Series. The levels were

!- typical of those found previously except for Bi-212. Bi-212 had not been previously detected; the detected value was about twice its LID.

V We ETS requires a LLD of not greater than 25 pCi/kg wet for I-131. This limit was exceeded on eleven occasions as follows:

Station 5 1] 21 July 36 31 47 August 44 52 48 Septe er 28 34 35 December 66 36 Iodine has a strong affinity for water; the moisture content in these smples was low due to very dry weather. %e wet to dry ratio for these saples l averaged 2.26; it is typically two to three times higher at other times. %e December smples were not received by the Contract lab until two weeks after their collection.

Adquate smples were not available at Station 17 in April and Deceber. A lot of difficulties have been encountered in obtaining adquate smples frm

, Station 17. Besides rather poor growth due to sandy soil and scant sunshine I

(it is located in a wooded area), the meager crop is depleted by the grazing of deer; then dry weather further empounds the difficulty in obtaining an adquate smple. Consideration is being given to relocating this grass plot and to the growing of collards.

1.3 Discharges to the River

[)

\/

%e ETS require the smpling of water, cles and sediment fra River Stations 170 and 172 which are about 1 mile upstrem and 2 1/2 miles downstrem, respectively. The upstrem station serves as the control station and the downstrem station serves as the indicator station. %e ETS also require the j smpling of American shad fra the area of the discharge structure.

We ETS require a gama spectral analysis of each smple. his analysis is performed on only the edible portion of the fish and cle smples. A tritim l analysis is also rquired on quarterly cmposites of river water for each l station. All of these analyses are perfomed by Teledyne Isotopes, Incorporated of Westwood, New Jersey.

f 1.3.1 River Water River water is collected using autmatic smpling machines; small smples are collected at intervals which are on the order of an hour. Water thus collected is picked up monthly; quarterly cmposites are cmposed of the monthly collections.

As usual, there were no positive results for the entire year on the gama scans of the monthly collections. Only scant results have been obtained in the past with this analysis. The only marrnade radionuclide ever detected was Ce-141; this occurred only once at an indicator station in the 4th quarter of l 1975.

The positive results in units of pCi/l for the tritium analysis of the quarterly cmposites are sumarized as follows ror the control and indicator stations, respectively.

] drinking purposes. As in all previous surveys, no intakes for drinking water

,/ were observed. If river water should becme used for drinking, the ETS require sa pling and analyses of the drinking water.

i 1.3.2 cles

%e ETS require a seniannual smpling of asiatic clas from the two river stations; if clas becme unavailable, smples of a ccanercially or recreationally important species of fish will be collected.

L Clas were sought on three occasions during the year but sufficient quantities were not available on any of these occasions. Consequently, on May 23-24 '

redbreast sunfish and largenouth bass were collected, then on Novenber 29 redear sunfish and largenouth bass were collected. The gamma spectral analyses detected K-40 and Cs-137 in each saple collected during the year and Cs-134 in the Novenber collections at Station 172.

O L)

i p %e levels for the naturally occurring ever-present K-40 ranged frm 2.78 to l

(') 6.05 pCi/gm wet. Se readings were typical of those found previously except for the maximm reading which was about 25% higher than the previous maximm l found in fish; this reading was frm a redbreast sunfish collected at Station I 170 in May.

ne levels for the fission product, Cs-134, in the redear sunfish and the largeouth bass were 0.0547 and 0.149 pCi/gm wet, respectively. %e ETS require a LLD of 0.13 pCi/p wet and a RL of 1.00 pCi/gm wet. The LID experienced was 0.01 pCi/p wet. Cs-134 had not been previously detected in fish smples.

ne Cs-137 levels in units of pCi/gm wet for all of the fish samples are sumarized as follows for the control and indicator stations, respectively:

n Max Min Avg s L_i-y MDD 4 0.0919 0.0480 0.0675 0.0182 4 0.310 0.0635 0.1386 0.1167 0.0711 0.3274 It is seen that there is no discernable difference between the average values at the indicator and control stations. These readings are within the range of those found previously except for the maximm value which is frm a largemouth bass collected in Novaber; the previous maximum of 0.23 pCi/gm wet was frm a redbreast sunfish collected upstream during preoperations. He ETS require a LID of 0.13 pCi/gm wet and a RL of 2.00 pCi/gm wet; generally a LLD of 0.03 p pCi/gm wet is achieved.

Se largemouth bass smple collected at Station 172 in Noveber had both the highest Cs-134 and Cs-137 levels for the year. %e maximm annual dose to an individual fra consming fish for a year with these concentrations would be 1.21 mre to the liver of a teenager; it would consist of 0.47 mre due to the Cs-134 and 0.74 mre due to Cs-137. This calculated dose is well below the design objective of 10 mre per year to any organ for liquid releases as specified by Appendix I to 10 CFR 50. Assmed values for the dose factors and uptakes were taken frm Revision 1 of Regulatory Guide 1.109, October 1977.

Both Cs-134 and Cs-137 are usually mongst the radionuclides emprising the liquid releases. An estimate of the average concentrations of these two radionuclides in fish at the indicator station due to the 4th quarter releases was an order of magnitude belnw the measured levels.

In past years, radionuclides were detected in fish smples by gama spectral analyses as follows: K-40 in nearly every smple; Co-60 in one smple during preoperations; Cs-137 in a substantial fraction of the smples; and Ra-226 in a total of 4 smples during preoperations and 2 during operations.

l.3.3 American Shad Because of its ccanercial importance, the ETS require that American shad be collected annually during the spring spawning period. W e allection was made on March 31. Naturally occurring K-40 was the only radionuclide detected in this single saple. %e level was 2.64 pCi/grn wet which is about the sme as that found previ>usly. Only K-40 has been found in previous smples of Arnerican shad.

1.3.4 Sediment The annual collection of sediment smples took place on May 17. The positive results of the gamna scan on each saple are presented below in units of pCi/gm dry.

All are naturally occurring except for the fission product Cs-137.

1.4 Discharges to the Ground (p) v' As reported in previous annual reports and also by LER No. 50-321/1979-21 (including its revisions, quarterly updates and other supplenents) groundwater with high trititun levels has been found to be present in two separate areas of the plant yard, nmely, an area centered just south of the Condensate Storage Tank for Unit 1 (CST-1) and an area about the north side of the Unit 1 turbine building. %ese areas appear to be essentially unrelated to each other in that the causes of the high trititrn levels are different and there appears not to be a good hydraulic connection between the two areas.

A portion of the tritiated groundwater slowly makes its way to the river via the drainage systens; the trititrn levels in these continuous releases are generally a fea orders of magnitude below the high levels found in the plant yard and that permitted by regulation. %e offsite doses due to these releases are anall.

1-16 O

U

p Were are three distinct water zones underlying the site; a water table, a Q local aquifer and a regional aquifer. 7quicludes separate and hydraulically isolate these zones fra each other. The vast regional aquifer whose top is a few hundred feet below plant grade is not hydraulically connected to surface waters in the' vicinity of the site. The shallow local aquifer is separated fra the regional aquifer by an quiclude which is about 100 feet thick; the top of the local aquifer is roughly 65 feet below the grade of the plant yard; it is hydraulically connected to surface waters in the plant environs. %e quiclude between the local aquifer and the water table is 40 to 50 feet thick. %e water table which is charged by the percolation of precipitation through the soil is unconfined. In the plant yard the water table more or less extends fra 10 to 20 feet below grade.

%e water table, according to the natural terrain, will drain both in a northerly direction (toward the river) and also in an easterly (downstream) direction toward a swap area which drains to the river. An analysis of the water levels fra various shallow test holes about the plant yard shows that groundwater flow in the water table has a strong local flavor. This phenmenon is attributed to the excavations performed during construction of the plant and the field routing of water pipes and electrical conduit runs.

'Ibese pipe and conduit runs are supported by cmpacted sand; any water introduced nearby will follow a path along the run, as this is the path of least resistance. Moreover, it is likely that sme of the excavations formed pockets in the aquiclude between the water table and the local aquifer in which groundwater accmulates.

f] 'Iwo separate subsurface drainage ditches, whose outfalls are at about 25 feet Q~ below grade, provide a syste for controlling the level of the water table.

nis network of subsurface ditches encircles the emplex of the main plant buildings - the service, turbine, reactor, control, and radwaste buildings for each unit. Roughly 70% of this encirclment is serviced by Subsurface Ditch No. 1 (SSl) whose outfall is about midway between the intake and discharge structures. The eastern side of this encirciment is serviced by SS2 whose outfall is on the east side of the protected area.

%e surface drainage systen includes a ' network of catch basins connected by underground ditches. Runoff fra the building roofs and the plant yard flow into these catch basins. The outfall for the surface drainage systen in the vicinity of the discharge structure is referred to as Yard Drain No.1 (YD1).

YD2 which services the east side of the plant yard has its outfall near that for SS2. %e outfall for YD3 which services the NW portion of the plant yard has its outfall frm beneath warehouse No. 6; the effluent would subsequently reach the river near the intake structure.  % ese surface ditches are separated fra each other.

Groundwater smples are sent to the Center for Applied Isotope Studies (CAIS) at the University of Georgia in Athens, Georgia. A liquid scintillation detector is used to determine the tritim content. Results are usually obtained within a few weeks; LLDs of 100 pC1/1 are regularly attained.

I-

' In the early fall CAIS determined in reviewing their procedures that their O.-

values for tritium in water had been in error as a result of not correcting for decay of the tritim standard. This made the results reported previously higher than they should have been -- up to 36%. %e corrective action taken .

, was : to modify the computer program used to reduce the data. All results i

reported herein for calendar year 1983 have been corrected.

In subsequent subsections, data stanaries for the year are presented for the groundwater samples taken -fra the locations associated with each of the two key areas and for _other locations. These locations are shown on Figure 1.4-1. Ebr each smpling location, the maxim m and minim m triti m levels are presented along with an annual average value of the positive readings and the ratio of the neber of positive readings to the total neber of readings. The

, annual average was determined by averaging the quarterly averages. Other information or data cssociated with the particular area may also be presented as warranted.

%ere have been no ETS requirments for the smpling of groundwater. since t 1978, at the time when HNP-2 began operation. Se high tritim levels being found in groundwater saples onsite have little impact offsite. At a meeting on Dec eber 19, 1983 with NRC Region II, it was agreed that the reporting in-the annual enviromental surveillance report of onsite tritim levels in-groundwater. was inappropriate and that such reporting in this annual report was-to stop after the report for calendar year 1983. %e reporting to the NRC 7

is to continue, as long as appropriate, by other means.

1.4.1 CST-1 Area The CST-1 area is centered about test hole P16 which is located about 5 yards south of the CST-1 dyke and several yards east of the condensate transfer I

peps. A pool of tritiated water appears to -be trapped in a pocket of the aquiclude which underlies this area. %e source of the tritium in this area is the .' leakage from the condensate transfer pmps and associated - plmbing which occurred in prior years as has been previously reported.

b Sampling locations affected are:

test holes N7A, T10 through' T16 and T18; outfalls SS2 and YD2; and catch basin PY24. 'Nst hole N7A taps the local aquifer; all other locations tap the water table. A data stunary of the

. tritim levels for each of these locations is presented in Table 1.4-1.

Over the past'five years the tritim levels in groundwater _ smples fra test hole - P16 have exceeded the RL (3.0 E4 pCi/1) . Attempts were made to saple

, test hole P16 monthly; each time the test hole was found to be dry. Catch basins PYl2 and PYl6 were also found to be dry in each attempt at sapling.

%e tritim . levels in the smples frm the - test holes - during 1983 were generally substantially lower than those found during 1982. %e levels at test hole T18 have been reportable for four years. %e single sample obtained at this test hole on June 7 had a reading of 6.05 E3 pCi/1; this reading is about 20 times less than expected. This test hole was found to be dry on other monthly attepts to saple it.

i Levels of 1.07 and 1.68 E4 pCi/l were found in the two smples taken at catch

[_, basin FY24. Levels of this order had on occasion been found at this location V} in past years.

1.4.2 Area About the North Side of the Unit 1 Turbine Building An early cause of the high tritium levels in this area was eliminated in March 1979 as has been previously reported. It was discovered that process water had been entering the ground a few yards frm test hole Pl7B through an open ended half-inch line buried to a depth of about 8 inches. Smpling locations which becae affected by this extraneous source of tritim include: test holes N9B, P15B, Pl7A, Pl7B, T2, T3, T4 and T8; and outfall SSI. Test hole Pl7A taps the local aquifer, all other locations tap the water table. A data smmary of the tritim levels for each of these locations is presented in Table 1.4-2.

Judging by the rise and subsequent decline of readings in succession at Pl7B, T4 and N9B and by the results of dye tests, the main body of this tritiated water which had entered the ground near Pl7B appeared to have migrated to the vicinity of the NE corner of the Unit 1 turbine building. Test Hole N9B is located at this corner. The readings at Pl7B and T4 subsequently dropped below the RL and are not of current interest.

%e reported readings at N9B reached a preliminary peak of 2.08 E5 pCi/l in May of 1980 then gradually decreased to 8.17 E4 pCi/l in June of 1981.

Increases followed, a level of 1.15 E5 pCi/l was reached in Deceber 1981.

Increases becue rapid during the early months of 1982; a new maxims of

/_\ 4.80 E5 pCi/1 was reported for the April 21 collection. Increases were also l b rapid at test hole T3 which is located a few yards west of N9B. These rapid increases triggered an investigation which led to the discovery in early May of 1982 of another extraneous tritim source.

@is source, as previously reported, was the leakage fra the Unit 1 precoat tank of the condensate polisher systs which is located near the north wall of the turbine building on the 130-foot level. Spillage to the floor flowed to the north wall and then under the wall panel to the outside of the building; l it then collected in the' pipe chase for the auxiliary stem boiler. Open joints between the pipe chase and the turbine building basement wall allowed water to enter the ground and flow along the bassent wall. his likely

, provided an casy path to the area of N9B and T3. %e open portion of the l turbine building north wall which provided this path to the outside of the building was prm ptly sealed.

A sep pmp reoves the water frm the pipe chase to the drain lines of the i turbine building roof which joins the yard drain system further downstrem at l manhole PYl. Subsequently, this portion of the yard drain syste passes through several catch basins to outfall YD3 which merges frm under Warehouse No. 6, and then to an open ditch leading to a culvert frm which discharge is made near the river. Seples are being taken regularly fra PY5 which is the first catch basin downstrem of manhole PY1 and frm outfall YD3, as well as l from the pipe chase; the results are included in Table 1.4-2.

/^T he levels at N9B were fairly steady during 1983; the average level of 2.80 E5 h pC1/1 was about three quarters of that reported for the previous year; the levels continued to be reportable each quarter as they have been since the first quarter of 1979. We levels at T3 decreased during the first half of the year but rose during the latter half of the year; the average level of 4.03 E4 pCi/l decreased by almost a factor of 2 to that reported for the previous year; except for the first and second quarter of 1983, the levels have been recortable since the second quarter of 1980.

It was noted in last year's report that the tritim levels during 1982 at test hole P15B, which is on the west side of the Unit 1 turbine building, had averaged more than 2.5 times those in 1981. W e annual average value for 1983 of 1.65 E4 pCi/l is about 4.8 times that reported for 1982. %ere was a step increase in the levels early in the year, then each quarter the levels diminished slightly. A gama scan was run on a smple collected on May 18; there was no gama activity above background.

ne levels at T2 were fairly constant throughout the year except for the reading of 1.75 E4 pCi/l for the smple collected on March 15. This reading was more than three times any found previously at this location. nis reading is out of line with all others taken at this location; the next highest reading during 1983 was 2.20 E3 pCi/1. %e annual average reading of 2.77 E3 pCi/1 was about the see as that reported for the previous year.

We tritium levels in the smples taken fra the pipe chase and catch basin PYS were found to be erratic ranging over two orders of magnitude with sudden p drastic changes, up or down, in the readings. For the pipe chase, both the

'_ Q maximm value of 2.94 E4 pCi/l and the annual average value of 3.50 E3 pCi/1 were nearly an order of magnitude less than those reported for the previous year. For catch basin PYS, the maximm value of 2.94 E4 pCi/l was less than half of that reported for the previous year while the annual average value of 2.64 E3 pCi/l was about 40% less than that reported for the previous year.

'Ihe readings on June 7 at YD3 were 3.29 E4 pCi/1; this reading is out of line with any other taken at this location as it is 4.7 times higher than the next highest reading. Nevertheless, this established a new maximm level for a saple collected at the outfall of one of the drainage systems; it also helped establish a new maximum quarterly average of 1.67 E4 pCi/1. The readings at outfalls are important because they measure releases to the public. %e previous maxima were set last year at SSl where the reading on December 12 was 1.12 E4 pCi/l and the 4th quarter average was 6.55 E3 EC1/1. The significant increase in 1983 is of concern. The new individual maximum reading is a factor of more than 90 below the MPC for tritim in unrestricted areas as given in 10 CFR 20. The new maximm quarterly average is equivalent to a dose of 0.43 mre to the total body. %is dose estimate is very conservative because it assmes that sme individual obtains all of his drinking water directly from the outfall which is generally inaccessible. % e quarterly dose limit resulting frm liquid releases as established by Appendix I to 10 CFR 50 is 1.5 mrm. @e average annual concentration of tritim for drinking water in comunity water systes is required to be less than 2 E4 pCi/1 according to EPA's National Interim Primary Drinking Water Regulations, 40 CFR 141.16.

Inspections of the exterior walls of the turbine buildings for both units were made to determine if there were pathways which would allow liquids to escape the buildings and enter the groundwater table. On June 29, all exterior walls except those in the condensate demineralizer/ ion exchange tank roms were visually inspected. In _ October the condensate deineralizer pits were inspected. Yet to be inspected are the polishing deineralizer backwash collection tank rom and the clean radwaste (CN) and dirty radwaste (DW) sm ps below the 112 foot elevation.

On the June 29 inspection, one penetration through the exterior walls, a 6" dimeter sleeve at elevation 112' 09", was found to have calcite deposits on the concrete wall directly below the sleeve. %is indicates groundwater had leaked into the building between the sleeve and the concrete. This penetration goes through a 3" expansion joint and the Unit 2 radwaste building exterior wall. %is penetration and other exterior wall penetrations which were inspected are higher than known spills for those areas.

On the October inspection, several of the condensate deineralizer/ ion exchange tank roms were found to have cracks in their exterior walls and several of the pits had water stains on the walls indicating the height of previous floods which had occurred. The findings indicative of potential or actual pathways to the groundwater table were as follows:

Unit 1 Vessel 1A - a fine crack in the northeast corner running the height of the corner, water stains on the walls to a height of approximately one foot; Vessel 1B - a thin crack extending frm the northeast upper corner. to the bottm of the north wall - calcite deposits extending the length of the crack ind!cated inleakage, water stains on the walls to the height of the condensate deineralizer valve nest penetrations; n

1-23

Vessels 1C,1D and 1G - no pertinent cracks, standing water to a depth of one O foot or so.

Unit 2 Vessel 2A - no pertinent cracks and no water stains on the walls; Vessel 2B - two cracks on the south wall, one extending frm the floor to a height of 12 feet, the other frm the floor to halfway up the wall, both had calcite deposits, no water stains on the walls; Vessel 2C - a crack on the south wall extended frm the floor to approximately ,

10 feet, no water stains on the walls; Vessel 2D - no cracks and no water stains on the walls; Vessel 2G - no pertinent cracks, standing water to a depth of one foot.

All of the pits inspected contain floor drains which should allow any standing water to flow to the turbine building floor drain emps. The drains for Vessels IC,1D,1G and 2G were found to be clogged; attenpts to unclog then at that time were unsuccessful.

It might be noted that due to the penetration which runs between the pits and the condensate demineralizer valve nest, no flooding will occur above the j height of the penetrations which are not sealed. These penetrations are located approximately two feet frm the floor of each pit allowing only two feet of standing water in the pits.

(Vn) l Actions to be taken include: the sealing of all pertinent cracks in the l

exterior walls of the condensate demineralizer/lon exchange tank roms with an elastic epoxy material, and inspection of the exterior walls in the polishing denineralizer backwash collection tank rom and the CRW and DRW smps below -

the 112 foot level. f 1.4.3 Other Incations and Other Results Tritium con'wination of a lesser degree was found in sme of the groundwater smples at most of the other locations. @e causes of the contanination at these locations generally differed fra those for the two key areas. A data stenary of the tritium levels for each of these locations is presented in Table 1.4-3. All of these locations tap the water table except for test hole PISA which taps the local aguifer. %e levels were generally lower in 1983 than those reported previously.

1.5 Crosscheck Progre Laboratories performing the analyses rquired by the radiological enviromental monitoring progra as delineated in Table 3.2-1 of the ETS participate in EPA's Enviromental Radioactivity Laboratory Interemparison Studies (Crosscheck) Progra conducted by the Enviromental Monitoring and Support Laboratory in Las Vegas, Nevada or in an quivalent progrm. Not all of the smple media / analyses cmbinations listed in the ETS are covered by the Crosscheck Progrm. Reported herein are the results of relevant participation in the Crosscheck Progre by these laboratories. Relevant participation is considered to consist of those analyses for sample media covered by the EPA Crosscheck Progrm which are the see as those required by the ETS to be a part of the radiological enviromental monitoring progrm. HNP conducted the gross beta analysis of air filters; all other relevant media / analysis cmbinations were conducted by Teledyne. Because of the time lag involved in obtaining results fra the EPA and the subsquent reporting of these results by the contract laboratories, not all of the 1983 results were available. The results reported herein also include the 1982 results which were not available last year.

Any results of determinations in the Crosscheck Progra for which disagrement can be established using the NRC's " Criteria for Cmparing Analytical Measurments" as described in Attachment 1, are investigated to determine the cause of the disagrement. Corrective actions are taken as warranted. 'Ihe results of any such investigations and corrective actions are reported in this section.

Oi Since all of the results reported herein are presented in the same tabular V format, an explanation of the column headings is provided. "Date" means the collection date given by the EPA. "Known" refers to the EPA known value i one standard deviation, s. " Result" is the average value measured by the laboratory i experimental s. " Resolution" is determined by dividing the known value by its s value. " Ratio" quals the " result" (value determined by the laboratory) divided by the "known" (value determined by EPA) . An explanation would have been provided in the text had any of the cmparisons shown "Disagrement". It should be noted that whenever the EPA known value is zero

, or the laboratory determined result is a "less than" value, a cmperison by l the NRC criteria cannot be made since the ratio cannot be determined.

'Ihe results of the gross beta and Cs-137 analyses of air filters are given in Table 1.5-1. Listed in Table 1.5-2 are the results of the I-131 and gama l analyses of milk smples. Table 1.5-3 presents the results of the gana and l tritim analyses of water. Shown in Table 1.5-4 are the results of gama analyses of food sa ples. All cmparisons show agrement with known values.

/D y) ATTACINENT 1 Criteria for Ccrnparina Analvtical Measurements his attachnent provides criteria for emparing results of capability tests and verification measursents. The criteria are based on an spirical relationship which cmbines prior experience and the accuracy needs of this progrm.

In these criteria, the judgment limits are variable in relation to the emparison of the Reference laboratory's value to its associated one sipa uncertainty. As this emparison, referred to as " Resolution" increases, the acceptability of a licensee's measurment should be more selective.

Conversely, poorer agreenent should be considered acceptable as the resolution decreases. ne values in the ratio criteria may be rounded to fewer significant figures to maintain statistical consistency with the ntunber of significant figures reported by the Reference Laboratory, unless such rounding will result in a narrowed category of acceptance. The acceptance category reported will be the narrowest into which the ratio fits fer the resolution being used.

%is chapter has shown the licensee's conformance with the radiological portions of the ETS. It has shown that all data were carefully exmined. A stenary, an interpretation and an evaluation (where warranted) of the results of the laboratory analyses for each type smple collected have been presented.

No measurable radiological impact upon the envirornent as a consequence of discharges to the atmosphere nor to the river was established.

%ere continues to be problems with high tritita levels in sme of the groundwater s aples taken at onsite locations; the envirornental impact i continues to be small.

%e relevant camparisons of the analytical measurements made by HNP and contract laboratories with those made by EPA in the Crosscheck Progra showed no disagrem erts.

2. METEOROLOGICAL MONITORING 2.1 Introduction During 1983, many changes occurred regart_ag the Plant Hatch meteorological. tower and its subsequent data collection program. In April a new 100m meteorological tower was put into operation. This tower has three levels: 10m, 60s, and 100m. Data collection continued through April using the old tower now designated as " backup" tower. r Two levels of data were collected at the 23m and 46m levels. For the purposes of running wind roses, data from both towers were combined (10m and 23m, 46m and 60m). However, due to the differences in elevation

' in delta-temperature between the two sites, the tables for different portions of the year could not be readily combined.

2.2 1983 Data 1

2.2.1 Data Recovery 1

Data recovery for all parameters was quite good for the year considering all of the changes made. For individual parameters, data recovery averaged about 96% with composite totals averaging about 94% for the lower levels and 87% for the upper levels (Table 2.2-1).

() 2.2.2 Nind Roses r

The wind roses (Figure 2.2-1 through 2.2-13) agree quite well, between levels both annually and seasonally. There are some differences between the 100m level and the lower two levels. This can be attributed to the different time periods of the 100m wind roses versus the 10m and 60m levels. A comparison of the 1983 wind roses with previous years shows some significant differences particularly when compared with 1982. There were many more hours of northwest winds and less hours of northeast winds in 1983 compared to 1982 data. These changes can be attributed to normal year-to-year climatic variations.

2.2.3 Temperature Data i

The temperature data (Figures 2.2-14 and 2.2-15) show good agreement with previous years. Overall, both the ambient and dew point temperatures were somewhat cooler than in previous years. This was particularly true 'during November and December when temperatures across the country

' were quite cold. The temperatures during the summer months were ,

considered to be above normal in the eastern U.S. -Temperatures at  !

Plant Hatch were lower than some previous years. This may be attributed '

to local conditions related to the moving of the meteorological-equipment.

2.2.4 Joint Frequency Tables '

( The joint frequency tables (Tables 2.2-2 through 2.2-6) agree very well with previous years. The table below shows joint frequency data for the last five years using wind speed and direction 46m vs delta temperature 46-10m. With the installation of the new meteorological tower during 1983 the level used in the table has changed to wind speed and direction 60m vs delta temperature 60-10m beginning May 1, 1983.

[v) 7725 7944 8361 7320 In 1983, the changing of the tower location has made little difference.

j With the increased difference between delta temperature levels one would expect to see less unstable and stable hours and more neutral hours during coming years. This would be caused by a higher rate of surface heating during the day and cooling at night at the 10m level but a small-relative difference in ambient temperature between the 46m and 60m levels. The additional height of normalization will cause more hours to be categorized as neutral than in the past.

2.2.5 Precipitation The precipitation total for 1983 was about 35 inches (Table 2.2-7). While this is still considerably below the climatic normal of 45 inches, it seems reasonable considering the dry conditions experienced in much of the eastern U.S. during the summer and early fall months.

Dear Mr. Welsh:

As required by the above referenced NPDES Permits, we hereby submit the Operation Monitoring Reports for each of the corresponding , power plants for the quarter ending June 30, 1983. Please note that the Plant Hatch report is incomplete. As of this date, my office has not received the river temperature data for the last half of June, nor the ~ circulating water chlorination data reports for the months of April and June. When this data is received, it will be transmitted to your office. l If you have any questions or comments, please advise. Sincerely, > n _f .

                                                                                                 'E b b e T. E. Byerley f-                                                                                -
