The infiltration characteristics of the surficial soils are quite low.

Four percolation tests, conducted in accordance with U.S. Corps of Engineers' procedures (Ref. 6.1-32), were performed in soils which varied in composition from silty clay to sandy silt and silty fine sand. The results indicated that the absorption rates are about 0.4 gal / day /ft2 Underlying the surficial soils to a depth of about 85 feet is sand and gravel with a few discontinuous, thin silty and clayey beds. The water table near the river is at a depth of about 40 feet, approximately the same as normal river stage. Perched water table conditions were encountered where thin, clayey beds occurred above the water table. The water table increases in elevation in the eastern portion of the site.

Permeability of the sand as computed from twelve grain size analyses ranges from 50 to 750 gal / day /ft2, 6.1.2.2 Models The rate of ground water movement is a function of the hydraulic gradient. The maximum gradient, occurring in the southeastern quadrant of the site, had an average slope of three percent. Under this condi-tion, the rate of ground water movement is about 3.3 ft/ day in the 2

southeastern quadrant (assuming permeability to be 175 gal / day /ft ),

This is a conservative value, since soils in this area are finer grained than those for which the permeability was calculated.

The rate of ground water movement near the river would be considerably lower, since the gradient is less. Based on a hydraulic gradient of 0.3 per-cent, the rate of movement would be on the order of 0.3 ft/ day.

V 6.1.3 Air 6.1.3.3 Preoperational Meteorological Monitoring Program The preoperational meteorological measurement program began at ZPS-1 l

on September 23, 1969, with installation of Mechanical Weather Stations (MWS) at two locations near the plant site. Wind data was collected from these stations until montioring was suspended on May 2, 1970.

Monitoring was resumed in April 1971 when a dual level 200-foot instru-l ment tower was erected 5500 feet north of the proposed cooling tower location along the bank of the Ohio River at a base elevation of 510 feet mean sea level (MSL). This tower was erected to define the air flow, stability, and humidity within the river valley. The distance of 5500 feet was intended to minimize the influence from the cooling tower, whose wake is expected to be discernible out to about 4000 feet.

The tower is close to the center of the valley in the same positf,n as the reactor building relative to the nearby terrain, and was located in a position expected to represent atmospheric transport and diffusion conditions at the plant site. Consideration was also given to avoiding areas of local drainage winds from lateral valleys, which might unduly influence the wind data.

V 6.1-15

ZPS-ER REVISION NO. 5 NOVEMBER 1981 Consistent with the recommendations of NRC Regulatory Guide 1.23 (Revision 0) concerning hill-valley sites, a second instrument tower 5

was installed in April 1971 to define the air flow and humidity of the atmosphere above the influence of the river valley. The single level 50-foot tower was erected at 882 feet MSL on a hilltop 5800 feet north-east of the cooling tower. This tower was extended to 150 feet on June 28, 1975. It was relocated from the original position occupied 1

by the 50-foot tower to approximately 5920 feet northeast of the coolir.g tower at a grade elevation of 815.2 feet MSL. The extension to 150 feet was made to avoid interference from nearby trees on wind measurements.

The recording of hourly averaged meteorological data from these two towers was begun in June 1971 and continued until December 1981, when 5

preoperational monitoring was terminated and an operational monitoring _

program was instituted (see Section 6.2).

Thus, a data base composed of over 10 years meteorological data was collected during the pre-operational monitoring program.

6.1.3.1.1 Instrumentation The instrumentation system used at ZPS-1 during the preoperational monitoring program complies with the requirements of NRC Regulatory 5

Guide 1.23 (Revision 0).

The sensors and related system equipment are listed in Tables 6.1-4 towers.

Sensor and 6.1-5, respectively, for the 200- and 150-foot model' numbers and locations on the tower are also given. The specifi-

-cations for the sensors and sensor and digital system accuracies are given in Table 6.1-6.

These accuracies are all within the requirements of Paragraph C4 of Regulatory Guide 1.23 (Revision 0).

6.1.3.1.1.1 Wind Direction s

Wind direction measurements were made using wind vanes at all four i

instrumentation levels. An output voltage on a scale of 9 to 5 volts is controlled by twin potentiometers. These two potentiometers, each of which covers the full 360*, are 180' out.of mechanical phase with each other. Their use in this manner eliminates the crossover problem of a single unit when the wind oscillates around the crossover point.

Wind direction is sampled by the datalogger at 1-minute intervals.

6.1.3.1.1.2 Wind Speed Wind run was measured from the beginning of the study in June 1971 i

until May 1980. The digitally recorded data was converted to wind' speed. The system utilized anemometer cups that, through a gear train,.

rotated a magnet past a reed switch to produce a closure once for every 0.1 mile of wind flow. Each switch closure produced a pulse j

that was accepted by the data logger and recorded on the tape. Each pulso also drove a side marker on the analog chart.

t Recording of data at the 150-foot level began September 1975.

bWind run was measured before May 1980, Temperature was measured at the 50-foot level until June 1975; no data c

were collected'from June 25, 1975, through August 31, 1975. Temperature measurement at the 150-foot level began September 1975.

Relative humidity was measured at the 50-foot level until January 1975; d

no data were collected from Januarr 20, 1975, through Fby 13, 1976.

O' Recording of dewpoint data began at the 150-foot level in May 1976.

• Recording of 150-foot turbulence data began September 1980.

NOVEMBER 1981 In May 1980, these sensors were replaced with wind speed sensors,-in V

which the an*aometer cups rotate a light chopper to generate a pulse

~

train whose frequency is proportional to wind speed. This train is converted by a signal conditioning card to a voltage, O to 5 volt scale, which is recorded on the analog chart and by the datalogger at 1-minute,

intervals.

6.1. 3.1.1. 3 - Temperature From the beginning of the study until May 1980, temperature was measured,

~

~

using a shielded and power-aspirated linear thermistor network containing a resistor with a high temperature coefficient.

In May 1980, the thermistor devices were replaced by shielded and power-aspirated platinum resistance thermometers. The continuous voltage output on~ >

a scale of 0 to 5 volts is recorded directly on the analog chart and is sampled and recorded once each minute on the magnetic tape.

6.1.3.1.1.4 Temperature Difference Temperature difference, a measure of atmospheric stability, was measured between the 30-foot and 200-foot levels of the 200--foot tower. Two temperature sensors as described above-were located at the different

~

levels on the tower. The voltage output difference between the,twc.

was amplified to a scale of 0 to 5 volts. This amplified output was sampled and recorded in degrees Celsius in the same ma,nner as, tempera-ture.

6.1.3.1.1.5 Atmospheric Moisture

~'

Before May 1976, relative humidity was monitored as a measbre of atmospheric moisture. The sensing element was a xeritron fiber, which changes shape as a function of relative humidity. It exerted a corres-ponding stress on a pair of thermally-matched silicon strain gauges' connected as a half Wheatstone bridge. The continuous output on a scale of 0 to 5 volts was recorded in the same manner as temperature.

In May 1976, the relative humidity sensor was replaced with chilled mirror sensors that directly measure dewpoint temperature. The sensing '

7 element is automatically held at the dewpoint temperature by means of.

'7 a photo-resistive condensate-sensing optical system. The mirror temperl ature is determined with an imbedded platinum resistance thermometer, which then represents the true dewpoint temperature. For dewpoints below 32' F, the system tracks the frost point. A control unit, using regulated bridge circuits, converts the resistance changes of the thermometer to voltage output.

high1 pass f'ilter circuit to obtain the standard deviation of the horizontal' wind direction. The unit works according to the principles presented by Jones and Pasquill (Ref. 6.1-33).

In the 15-minute mode used at 'ZPS-1, the unit outputs the 15-minute average value of the standard deviation, where the standard deviation is based on 180 consecutive vditages sampled at 1-second intervals. This value is equivalent to a high-pass 3rdb frequency of 0.0055 Hz and encompasses that portion of the turtrulence spectrum that is responsible for initial

' dispersion of effluent cloucs. The voltage is converted to sigma in

<' units of degrees; the saaling is 0* to 45* for 0 to 5 volts d-c.

\\ 6.1.3.1.2 Data Loggng and Racording i

~

In t'ne preoperational monitoring system, MRI Model 1001 Transmitters-were used to convert input signals from the sensors to an output signal "s,

,of a to 5 wolts.

In the original system design, data from the 200-foot tower was digitized by an MR1 Model 1750 Digital Datalogger and recorded on a Kennedy Model 1600/5 Incremental Magnetic Tape Recorder, a 7-track, 556 bits per inch unit thatased 1/2-inch magnetic tape. Analog data from the 200-foot and 150-~ foot towers were recorded by Model A601C Esterline-Angus re-corderi, with MRI event markers added onto two of these recorders.

The reco'rderri accept. analog signals and event pulses directly from the

^

t transmuter. Effective chart width is 2 inches. Magnetic tapes and re-cprder'charta.were changed at tiwo week intervals and were submitted to the meteorological com -' Mnt for review. The meteorological consul-tant _ digitized the.de the 150-foot tower using the analog recorder char,ts.

adjustments were made at other times. All meters and other equipment used in calibrations were in turn calibrated at frequent intervals.

Evidence of accuracy,,Fhich is traceable to the National Bureau of Standafdw has beetsrecorded for each calibrated instrument.

6.1.3.1.3.2 Mainten$1nce Inspection and maintenance of all equipment followed procedures in the rpferented manuals. All equipment was thoroughly inspected before each sy9 tem calibration.

Indiyidual components were removed for servicing at intervals specified ir.Jthe manual or more frequently if the need was t

detected. If required maintenance could not be accomplished at the site, the component was re.tcrned to the meteorological consultant or to the manufacturer. -In case of major trouble in the system, an electronics technician or engineer was dispatched by the meteorological consultant to the site.

6.1.3.1.3.3 Onsite Monitoring 7-The site was visited frequently by an electronics technician employed

-' by Cincinnati Gas & Electric. This indi.idual checked all components and was qualified to handleircutine system maintenance, to check and y

uake zero-set adjustments of the analog recorders, to clean and ink the pens, and to examine *.he, analog traces for reasonableness. Pro-s cedures for these operations were available at the site.

In addition to

' f'~}

this routine monitoring, chart and tape changes, servicing of the re-cordera, cleaniag of the instrument shelter, careful inspection of

(,j analog traces, and minor repairs and adjustments werc done about twice each week.

6.1.3.1.3.4 Data Monitor,1,ng n

.All analog charts were carefully inpsected for discrepancies or evidence of malfunction as soon as possible af ter receipt by the meteorological consultant. The magnetic, tapes were similarly processed and the pre-

~

11minary listing examined and compared with the analog values. Because a knuvledge of expected-values is required, a professional meteorologist was assigned to this task. The primary purpose of this quality control procedure was to detect malfunction or the need for calibration as soon r

as possible. When a need for servicing was detected, the meteorological consultant's Projer.t M anager and Field Oparations Manager were advised inmediately.

u 6.1.3.1.h Data Analysis Procedures Designed for maximum accuracy, the analysis procedures used in the Zimmer project are responsive to Regulatory Guide 1.23 and folicy the guidelines provided in Regulatory Guide 1.70, Standard Format and Con-tent of -Safety Analysis Reports for Nuclear Power Plants (Revision 1),

6.1.3.1.4.1 Data cuality Control As described in Subsection 6.1. 3.1. 3. 4, all data were subjected t o a quality check as soon after receipt as possible. The analog charts received a detciled inspection which included, but was not necessarily limited tc3 the following iters:

Chart timing - Timing was checked to see whether it matched a.

reported on and off times and the off time of the previous charg. Chart was re-timed if necessary, b.

Adherence to scale.

Reasonableness of data - This evaluation included check!ng c.

for the proper diurnal variations of temperature, humidity, and temperature difference; the absolute values of these and other variables; and the relationships among such variables as wind speed, temperature, and temperature difference, d.

Continuity of data and instrument operation.

e.

Evidence of power interruptions and malfunctions.

For digital systam, a programmed check of the magnetic tape was made as soon as possible after receipt to determine whether the data were usable. For usable data, a system " dump" was made and the data were

(}

\\s /

given a preliminary inspection for consistency, reasonableness, and The data were then converted to engineering units, the gaps gaps.

were filled by data from the analog charts, and a preliminary data listing was obtained.

These data were then compared on a random sample basis with data from the analog charts.

This quality control procedure detects electronic or sensor drift or malfunction, improper mechanical zero adjustment, or any other soruce of error in the data. Much of the time, erroneous data can be retrieved. Retrieval was usually accomplished on the basis of a recalibration and/or appropriate comparisons with data of kncwn quality obtained under similar conditions.

If valid correction factors could not be determined, the questionable data were not used in summaries and anslyses.

6.1.3.1.4.2 Data Reduction Data in the fot= of voltages or impulses were sampled and recorded on magnetic tape at 1-minute intervals as described in Subsection 6.1.3.1.1.

These data were converted to engineering units with appro-priate scale actors and averaged to obtain the hourly values that were used in the analyses. Before November 1977, wind direction, temperature, relative humidity, and temperature difference were averaged over a 15-minute period centered on the hour. Because sigma is already averaged, the reading at 7.5 minutes past the hour was selected. All g

)

data were entered on the new tape as hourly values.

The same averaging

(

periods for digital data reduction were used for the analog data.

6.1-20A

ZPS-ER REVISION No. 5 NOVEMBER 1981 Beginning in November 1977, when the ESC CDL-700 digital datalagger was installed, data reduction was performed as just described except that each hourly average was composed of four 15-minute averages, rather than a single 15-minute average centered on the hour.

6.1.3.1.4.3 Analysis The hourly averaged data from the preoperational monitoring program have been compiled into a series of summary tables, most of which are produced by month, season, or year. The data have also been used as input to the computation of X/Q estimates in Subsections 6.1.3.2 and 6.1.3.3.

Summaries for selected periods of data are referenced in Section 2.6.

A separate report, entitled " Final Summary: Preoperational Meteorological Monitoring Program for the Wm. H. Zimmer Nuclear Power Station," summarizing the entire preoperational data base (July 1971 through December 1981) is in preparation and will be available in mid 1982.

6.1.3.2 Models 6.1.3.2.1 Short-Term Diffussion Estimates Cumulative frequency distributions of hour centerline X/Q factors were calculated with the equation:
