u I. INTRODUCTION This report has t- ro objectives. The first is to present the results of an evaluation of the effect on the temperature lapse rate ( AT) cn the permanent onsite meteorological system of two onsite ponds at the Davis-Besse Nuclear Power Station site. The second objective is to explain the differences in onsite meteorological data collected during the December 1,1969-November t 30, 1970 period and the August 4,1974-August 3,1975 period.

O 1 i

II . DATA COLLECTION SYSTEMS The data used fur both analyses come from two onsite meteorological towers approximately 2200 ft apart (see Figure 1). The first is a 300-ft tower erected in October 1968 (old tower) and located near the center of the site. The second tower is a new 340-ft tower located in the southwest corner of the site. This tower became operational in August 1974 and will be the permanent onsite meteorological system. Data for the December 1969-November 1970 period submitted in the Final Safety Analysis Report for Unit 1 and the Preliminary Safety Analysis Report and the Environmental Report-Construction Permit Stage for Units 2 and 3 wire obtained from the old tower. The old tower was refurbished, a new 35-ft temperature sensor was added, the instrumentation was completely calibrated and observations recommenced in December 1974 The temperature lapse rate data available from the old tower are AT ""

III. DATA ANALYSIS In order to evaluate the possible effect on lapse rate of two ponds adjacent to the new tower concurrent data were collected and analyzed from both towers for a 1-yr period, December 16, 1974-December 15, 1975. AT obser-vations from the two towers were compared on an hourly basis. These compar-isons were made for various grouped wind directions, based on over-pond and over-land wind flows.

As shown in Figure 1, the two onsite ponds (labeled A and B) lie to the north of the new tower. The temperature of air near the surface associated with winds blowing from NNW clockwise through NE might be modified by the ponds and affect the 6T measurements on the new tower. Since the old tower is up-wind of the ponds during these wind flows, it would not be affected. Comparisons of AT observations at the two towers during these air flows and during flows for which the ponds would have no effect on either tower (ENE clockwise through S, WNW, and NW only) were made in order to differentiate the effects of the ponds from expected differences between the two towers. Since the effect on stability classes is the main concern, all comparisons used hourly averages of 6T classified into stability classes (ranging from A, the most unstable, through G, the most stable) as defined in Regulatory Guide 1.23. These stability classes f were then correlated through the use of contingency tables. Listed below is a summary of the comparisons made to determine the effect of the onsite ponds on 6T measurements made on the new tower. The results of these analyses are presented in Section IV.

Wind data used are from the 35-ft level of the new tower meteorological system (35-ft satellite tower).

Section V of this report discusses the rationale for the differences between the 1969-1970 and the 1974-1975 onsite meteorological data.

These differences caused a significant decrease in the 5th percentile X/O values calculated for 1974-1975 when compared to the 1969-1970 data period. The difference is attributed to the facts that (1) the bottom tempera-ture sensor on the old tower is only 5 ft above the ground, and (2) the sensors utilized on the old tower are closer together. The earlier data period used AT 145'-5, f r stability data while the more recent data period used AT

' 250'-35

Section V of the report shows the effect of the 5-ft bottom temperature sen-sor and the closer sensors by comparison of AT observations from both towers. All wind directions are considered. As before, comparisons are

, made for stability classes using contingency tables. Listed below are the comparisons made:

In addition, comparisons of AT145'-5' (used for the 1969-1970 period) versus AT250'-35, (used for the 1974-1975 period) were made for the December 1974-December 1975 period to directly show the difference between the two data sets.

All comparisons were made'on a monthly, seasonal and annual basis.

However, monthly data are presented only where cppropriate.

( AT250'-35, data were used to define stability categories for X/Q calculations for the August 1974-August 1975 period). The data in these tables are based on r AT stability classes and are presented in terms of the number of observations for which: (a) tne two towers agree; (b) the new tower indicates a more stable condition than the old tower; and (c) the new tower indicates a more unstable 1

condition. Tables 1 and 2 also present an additional column that indicates the profected frequencies for the three categories defined above when the winds blow over the ponds toward the new tower (NNW-NE). These were computed by making the assumption that the actual observations presented for winds not blowing over the ponds toward either tower are a realistic representation of the 6T data distribution between the towers. Then, using individual seasonal and annual frequencies of the three categories defined above for these non-affected winds, the projected number of occurrences for each category were l calculated based on the total number of observations for each season of NNW-NE winds. By comparison of the actual observations with the projected observations for NNW-NE winds a determination can be made of whether the t ponds are affecting observations at the new tower. Careful examination of Tables 1 and 2 does not show any significant differences between what is projected for the overpond flow and the actual observations. The high frequency

'{

of observations in direct agreement plus the close agreement of actual obser- !

i vations and projected observations indicates little or no measurable effect of the ponds on 6T distributions at the new tower. This is to be anticipated because of the nearness of large bodies of water (Lake Erie and surrounding !

marshes) and the relatively small fetch across the ponds (see Figure 1).

i V. THE RATIONALE FOR THE DIFFERENCES IN ONSITE METEOROLOGICAL DATA BETWEEN THE DECEMBER 1,1969-NOVEMBER 30,1970 AND A GUST 4,1974-AUGUST 3,1975 PERIODS As stated in Section III, possible causes for differences in meteorological data between the two periods (limited mainly to significant differences in AT distdbutians) are that the bottom temperature sensor on the old tower was only 5 ft from the ground and the vertical separation of the sensors used for X/Q calculations was only 140-ft compared to a bottom sensor height of 35 ft and a separation of 215 ft for the new tower.

The meteorological system used to collect data for the December 1969-November 1970 period (old tower) was installed in October 1968, prior to the issuance of Regulatory Guide 1.23, and did not meet the requirements outlined in Regulatory Guide 1.23 for instrument height, instrument accuracy, or data collection and recovery. The meteorological system used to collect data for the August 1974-August 1975 period (new tower) was installed in August 1974 and meets Regulatory Guide 1.23 requirements.

The most significant difference is the evaluation above ground level (AGL) of the bottom temperature sensor. This sensor is at 5 ft AGL on the old system and is at 35 ft AGL (consistent with Regulatory Guide 1.23) on the new system.

The height difference can result in significantly different temperatures since thd air temperature near the ground is very dependent on the surface temperature of the ground. During the course of a day, the ground temperature can fluctuate depending primarily on the amount of insolation (or radiational cooling) and the wind speed. Depending on the meteorological conditions, large fluctuations can occur in relatively short time periods. Because of the influence of the ground on the air temperature, the closer a temperature sensor is located to the ground the more it will be influenced by the ground temperature. When the temperature sensor is closer to the ground it would be anticipated that more of 8

the extreme stability conditions, both stable and unstable, would be evident.

. Another biasing effect, although less pronounced than that caused by temper-ature sensor beleg closer to the ground, is the smaller difference in height between the temperature sensors for the AT measurements on the old system (140 ft vs 215'ft). The smaller separation would also tend to increase the number of extreme conditions and show less neutral conditions. (Regulatory Guide 1.23 stipulates that. upper temperature readings should be taken at the approximate height of release of radioactive material, which for Davis-Besse is approximately 250-ft AGL, the height of the temperature sensor being used for X/Q calculations for the new system).

The effect on stability class distributions based on 6T of the temperature sensor being at 5-ft AGL is very pronounced with an especially strong bias toward the unstable categories and a lesser, yet also pronounced bias toward the stable categories. Table 3 presents stability distributions on a seasonal and annual basis for AT 295'-5, and 6T 295'-35, (both on the old tower). This table quite clearly shows the bias toward extremes caused by the low elevation of the bottom temperature sensor. Contingency tables of these two sets of

(

observations are presented in the appendix. T..ese tables also clearly show the bias caused by the sensor being at 5 ft. Especially noticeable are the large number of occurrences of A, B, and C stability for AT 295'-5' associated

( with neutral conditions for 6T 295'-35'*

The effect on stability distributions of a smaller separation of sensors is not as pronounced as the effect of a bottom temperature sensor being close to the ground but nevertheless is quite evident. Table 4 presents comparisons of AT 295'-5

c It has been shown that the effect of a bottom temperature sensor close to the ground or a smaller separation of sensors can have a pronounced effect on stability clas distributions . When both these effects occur in combin-ation, a large difference in stability class distributions is noticed. Table 5 presents a comparison of stability distributions of AT e used for 145'-5' X/Q calculations for the earlier data period) and 6T250'-35' (the 6T used for X/Q calculations for the more recent, August 1974-August 1975, data period).

r These concurrent stability distributions from the December 1974-December 1975 period show a very large difference between the two AT's, especially for the unstable categories. There is also a notable difference for the "F" and "G" stability categories, enough to substantially affect 5% X/Q values.

Figures 2 and 3 show the difference in middle of the day AT distributions caused by both a bottom temperature sensor close to the ground and a smaller separation of sensors by comparing AT14 5 '-5'

only, in order to eliminate the large positive AT values that sometimes occur at night and cause off scale recorder readings because of recording limitations . When this occurs, of cour ' . the actual AT value is not known. (The AT scale, however, amply covers the range needed for deter-mination of stability classes.) The values presented are 8-day running averages for all wind directions. The 8-day running average was used to smooth any extreme short-term fluctuations caused by normal weather system passage. Examination of Figure 3, which directly compares AT O 250'-35,, shows very clearly the differences of the 145'-5'

two AT data sets. Both indicate the same general trends, however, AT 145'-5, as mud larger varianons especiaHy in the spMg and summer.

VI. DATA RECOVERY Table 6 presents the data recovery rates for the joint occurrence of AT stability classes. Data presented in the appendix have the total number of observations used indicated on each page. Data recovery was exceptionally low during the summer months because the temperature

. bridges on the old tower could not be adjusted to proper specifications during a quarterly calibration. This necessitated removal of the bridges and sending them to the manufacturer. Removal of the bridges caused large data losses for AT145'-5, and 6T295'-5' during June, July, and August 1975.

SUMMARY

AND CONCLUSIONS The data presented in thit report for onsite temperature lapse rate from e the December 16,1974-Ds. :: ember 15, 1975 period have shown the fol-lowing:

1) The onsite ponds have no or very little effect on AT data collected at the 340-ft meteorological tower.

2) Differences in 6T stability distributions between the December 1969-November 1970 data and the August 1974-August 1975 data are caused by a temperature sensor located much nearer the ground (5-ft vs 35-ft) and a smaller separation of sensors (140-ft vs 215-ft) during the December 1969-November 1970 period. Both these effects cause biasing toward the extreme stability categories, A and G.

With a higher occurrence of the G, extremely stable, cate-gory, the December 1969-November 1970 data provided overly conservative 5% X/Q values, f
