INTRODUCTION

~

In accordance with NRC Regulatory Guide 1.111, Revision 1, issued July

1977, terrain adjustment factors should be applied to the atmospheric dilution factors which are derived based on the straight-line model. Cur-rently, the terrain adjustment factors used at Beaver Valley are the default terrain adjustment factors of NRC Regulatory Guide 1.111, Revision 0, issued March 1976.I ) In order to assess the conservatism of the default values as applied to the straight-line model used to calculate long term dispersion factors for the Beaver Valley Power Station, Duquesne Light

Company requested NUS to determine site-specific terrain adjustment

- factors by comparing the straight-line model to a segmented plume model (NUSPUF) which can account for temporal variation in the meteorology.

Hourly averages of onsite meteorological data for the period January 1, 1977_- December 31, 1977 were used for the analysis. For releases made from the top of the containment, which are considered to be ground-level releases, the maximum annular sector terrain adjustment factor was deter-mined to be 2.3 and occurred within 1 mile west-northwest of the plant.

For releases made from the top of the cooling tower the maximum annular sector terrain adjustment factor was determined to be 1.8 and occurred i

within 3 miles south of the plant.

SITE TOPOGRAPHY The Beaver Valley Power Station is located in the Ohio River Valley at a bend, giving the valley a general northwest and northeast orientation from the plant. Figure 1 shows the location of the plant and the 500-ft meteoro-logical tower and the topography for a 5 mile radius. Figure 2 shows the general topography out to 20 miles..The river runs to the northeast approxi-

)

mately 9 miles before bending towards the south and runs approximately 3 miles to the northwest before bending to the southwest. The river valley 1

)

is approximately three-quarters of a mile wide at the location of the plant

. and varies from about one-half to one mile out to 9 miles northeast and 3 miles northwest of the plant. The valley walls rise steeply to 400 to 500 feet above the valley floor within a quarter mile of the plant. In general, the topographic features reveal a complex terrain. Channeling of air to l

l

- follow the configuration of the Ohio River Valley is anticipated to some i

extent. In addition to the channeling of the air, a drainage flow would be expected to develop in the valley during the evening hours when light winds and stable conditions occur. Drainage winds are expected to occur from I

the southeast sector at the location of the plant and any effluents released from the plant during these conditions would be channeled down valley L

towards the northwest sector.

METEOROLOGY A.

Meteorological Data Acquisition and Data Recovery The meteorological data acquisition system consists of a computerized data processing system which collects and reduces data on a real-time basis and an analog system as a backup to the digital system. The combined digital and analog data recovery during the data period January 1,1977 -

December 31, 1977 for joint AT and 35-ft wind data was 91 percent 150ft-35ft and 87 percent for AT and 500-ft wind data. Loss of data were 500ft-35ft generally attributed to drifts or trips in the telemetry for digital data or l

improper inking of the recorder pens for analog data. Data were lost on a random basis, except for one period in December 1977 when there was a malfunction in the Endevco signal conditioner resulting in a two week loss of AT500ft-35ft data.

)

B.

Local Meteorology The annual wind roses with associated average wind speeds for the 35-ft and 500-ft levels for the period January 1,1977 - December 31,1977 are presented in Figure 3. The winds are primarily from the southwest quadrant which agree with the general air flow of the region based on NWS data at Pittsburgh International Airport.( } There is a secondary peak in the wind l

direction frequency for the 35-ft level which is attributed to the drainage flow off the southeast slopes. The annual average wind speed at the 35-ft level is 4.4 mph and 10.8 mph at the 500-ft level.

L

(

The stability classification determined from temperature differential (AT) is based on NRC Regulatory Guide 1.23.

The annual frequency distribution

/

of AT150ft-35ft and AT500ft-35ft for the period January 1,1977 - December f

31, 1977 is presented in Table I and the annual joint frequency distributions

~

(JFD) of AT150ft-35ft and 35-ft wind data are presented in Appendix A and Appendix B for AT500ft-35ft and 500-ft wind data.

Examination of the AT distribution indicates that neutral and slightly stable conditions are predominant for AT150ft-35ft data. In addition there is a high frequency of extremely unstable conditions. Neutral conditions are predomi-l nant for AT500ft-35ft data. The JFDs for AT150ft-35ft data indicate unstable conditions are usually associated with moderate wind speeds and winds from the southwest sectors while stable conditions are usually associated with light wind speeds and winds from the east through south-southeast sectors.

The JFDs for 6T500ft-35ft indicate neutral conditions are the predominant stability class and are associated with moderate wind speed from the south-i f

west sectors.

LONG TERM DIFFUSION ESTIMATES A.

Atmospheric Dilution Factors and Terrain Adjustment Factors Annual average X/Q values for the straight-line model (NUSOUT) were calculated in accordance with NRC Regulatory Guide 1.111, Revision 1, l

issued July 1977. Annual average X/Q values for the segmented plume model (NUSPUF) were calculated in accordance with Reference 5.' Onsite Beaver Valley meteorological data for the period January 1,1977 -

December 31, 1977 were used in the calculation for both models. Figures l

4 and 5 present the isopleths of the annual average X/Q values for a l

i ground-level and elevated release, respectively, based on the straight-1 line model. Figures 6 and 7 present similar information, based on the L

segmented plume model. Figures 4 and 6 indicate a similar isopleth pattern between the straight-line model and NUSPUF for the ground-level release.

The effect of drainage wind associated with low wind speeds and stable conditions is clearly discernable with maximum X/Q values elongated down valley to northwest. Figures 5 and 7 indicate the similarity of the isopleth patterns between the straight-line model and NUSPUF for elevated relea se s. Maximum X/Q values occur to the northeast of the plant as a result of the prevailing southwesterly wind direction.

Since the straight-line model does not consider temporal variations in the airflow of the site region, terrain adjustment factors for the Beaver Valley plant were developed based on the ratio of the X/Q values derived from e

segmented plume model to those derived from the straight-line model.

Figures 8 and 9 present the ratios of NUSPUF to NUSOUT for ground-level and elevated releases, respectively. Table II presents the maximum ter-rain adjustment factor for each annular sector for a ground-level release and Table III presents the maximum terrain adjustment factor for each an-nular sector for an elevated release. For distances where the ratios were i

less than 1.0, the terrain adjustment value was conservatively set to 1.0.

Models 1.

Straioht-line Model L

The annual average atmospheric dilution factor calculations using the straight-line (NUSOUT) model assumed a uniform horizontal distribution I

within a 22.5 degree sector. Stability was based on AT. Calms were distributed based on the directional frequency of winds in the 0.75 - 1.5 i

mph range and were assigned a wind speed of 0.3 mph.

X/Q values were calculated in accordance with the methodology of Section C.1.c and C.2 of NRC Regulatory Guide 1.111. The basic equation is as follows:

releases for limited vertical mixing due to the mixing depth. A representa-l tive mixing depth for the Beaver Valley area was set to 1000 meters. The values of o are based on the dispersion curves presented in NRC Regula-gy l

tory Guide 1.111.

i Because of the sharp rise in terrain within a quarter mile of the cooling L

tower (to 400 to 500 ft above the valley floor), the release height was effectively zero for the entire surrounding region. The building wake adjustment factor was not considered in calculations for releases from the top of the cooling tower.

2.

Segmented Plume Model The calculation of X/Q values based on NUSPUF was performed according I

to the basic concept that a continuous plume may be segmented into an infinite number of puffs. The location of each puff in the plume can be found by an integration of the wind field and the concentration in the con-tinuous plumes at a specified time can be obtained by the integration of the contributions of all puffs which have been released at or prior to that time.

Limited vertical mixing due to the mixing depth is incorporated in the NUSPUF model. The mixing depth was taken as an average of 1000 t

(

i meters. Similarly, as in the straight-line model, because of the sharp rise in terrain in a relatively short distance, the effective source height was assumed to be zero for the elevated release. Building wake was included in the ground-level release calculations but was not included in the elevated release calculations.

i C.

Effect of Cooling Tower Plume The X/Q values calculated by NUSOUT and NUSPUF did not consider that effluents released from the top of the cooling tower are entrained in the f

j cooling tower plume. Therefore, a qualitative assessment was made to determine the effect of plume buoyancy and drift separately on ground-level X/Q values. Two analyses were made, both with the assumption that the effluent was completely entrained in the cooling tower plume.

Both analyses used models which are essentially straight-line, i.e., as l

in the NUSOUT model, spatial and temporal variations were not accounted for. The calculations were made using the same meteorological data set I

(

used for the NUSOUT (and NUSPUF) calculations, i.e., January 1,1977 through December 31, 1977. Terrain heights above plant elevation were included in both analyses. The first analysis assumed that the vent re-leased gas is completely mixed within the vapor plume and had a Gaussian

)

l distribution both in the vertical and crosswind directions. The resulting l

calculations indicated that annual average ground-level X/Q values for a buoyant vapor plume traversing and impacting on the complex terrain in the vicinity of the Beaver Valley plant were everywhere (out to 20 miles from the plant) less than the corresponding values obtained by the use of the NUSOUT model, f

(

9 i

The second analysis very conservatively assumed that the vent release gas was completely absorbed into the drift droplets released from the cooling tower. Ground-level X/Q values (based on airborne drift particles) and D/Q values (based on ground deposition of drift) were calculated. They showed that annual average X/Q values for airborne drift were everywhere (within 20 miles of the plant) less than the corresponding X/Q values obtained by use of the NUSOUT model. The drift fallout did, however, result in higher deposi-tion rates in the immediate vicinity (within about 2 miles of the plant) and in l

lower depleted X/Q values beyond 2 miles than obtained by the NUSOUT model. Considering the very conservative assumption that all the elemental l

i iodine would be absorbed bythe drift droplets a s opposed to a more realistic assumption that the absorption ratio of condensed vapor plume to drift would be about 1000 to 1, the apparent non-conservatism of the NUSOUT model

(

(which uses Regulatory Guide 1.111 curves) is not considered significant.

In summary, neglecting the temporal variability of meteorological parameters, the NUSOUT model, which did not consider buoyant plume rise or drift, is qualitatively shown by ccoling tower analyses to be realistically conservative for calculating annual average dispersion and deposition factors for effluents

)

released from the top of the Beaver Valley cooling tower. When corrected by l

the adjustment factor discussed in the previous section, the straight-line (NUSOUT) model is considered realistically conservative for making calcu-lations needed for dose assessments of routine releases from the Beaver Valley Power Station.
