1. 0 INTRODU CTION h Presented in this report are the summaries of the meteorological data collected during the first full year of operation of the instrumented tower at the Pebble Springs Site. This tower was constructed for the purpose of obt aining meteorological data necessary for preparation of Safety Analysis and Environmental Reports required for construction and operating licenses. Designed to meet the specifications established by the Atomic Energy Commission (AEC), the tower system began operation on December 31, 1973. The summaries presented here were computed for the period January 1,1974, through December 31, 1974.

The purposes of this report in addition to presenting the summaries are to describe the system and its measurements, present the models used for computing relative concentrations, and discuss the results. The descrip-tions and discussions are presented in the following paragraphs. The tables are presented in groups separated by titic pages. This method facilitates comparisons and obviates the need for numbering. I

2. O METEOROLOGICAL MEASUREMENT SYSTEM l The instrumented tower described here is located one-third mile west-northwest of the Containment.

2.1 INSTRUMENTATION The instrumentation system used in the program was designed to meet the requirements and specifications of AEC Regulatory Guide 1.23. The primary system records digital signals on magnetic tape and the original analog signals on strip charts. The backup AT (30 ft to 130 ft) and wind speed and direction (at 30 ft) sensors record on separate analog strip charts . Primary a-c power is supplied by a 30-kW diesel generator with propane generator backup. An Elgar Uninterruptibic a-c Power 1 Source (UPS) provides additional backup and ensures continuation of power during interruptions from the primary and backup sources. This instrumentation system is described below. O 2.1.1 METEOROLOGICAL MEASUREMENT SYSTEM (Tower) The meteorological system referred to as the meteorological tower is designed to obtain measurements as indicated on the next page. The sensors and related system equipment are listed in Table 2-1. Model and serial numbers and locations on the tower are also given. The specifications for the sensors and the sensor and digital system accuracies are given in Table 2-2. These specifications are all within the require-l ments of Paragraph C4 of Regulatory Guide 1.23. The measurements 1 are described in Section 2.2. 2.1. 2 DATA LOGGING AND RECORDING MRI Model 1001 transmuters, containing the signal conditioning circuit boards listed in Table 2-1, are used to accept signals from the sensors 2

                       . and convert the input voltages to a scale of 0 to 5 volts dc. The MRI Model 1751 Digital Data Logger digitizes the signals from the transmuters

! and delivers them to the Kennedy Model 1600/360 Incremental Magnetic Tape Recorder. The logger handles 20 analog and 4 digital inputs, and it has a select capability and a 3-digit front panel display. The recorder is a nine-track 800 bpi unit that uses 0. 5-in. magnetic tape. Tapes are changed monthly. Analog recording is handled by six Model 1907 dual-channel recorders. Each of these recorders consists of two Model A602C Esterline-Angus recorders and two MRI event markers. The recorders accept analog p 1 _/ 3

signals and event pulses direct from the transmuter. Effective chart p width is 2 inches. Charts are changed every two weeks. 2.1. 3 POWER SUPPLY l Power is supplied by an extension from the local commercial service. An l Elgar UPS ensures no interruption of power during switching and can supply power (from an augmented set of batteries) on its own for several hours. The UPS also serves to maintain frequency at 60 Hz 0.25 percent. 2.1.4 LIGHTNING PROTECTION The tower and each of the guy wires aie grounded with standard grounding kits. A kit consists of a copper rod driven 6" into the ground and a No. 4 copper cable connecting the rod and the object to be grounded. Two grounding kits are attached to the base of the tower, and one is attached to the base of each of the guy wires. These comprise the lightning protection system for the meteorological tower.

2. 2 MEASUREMENTS The nature of the various measurements is as follows:

2.2.1 WIND DIRECTION An output voltage on a scale of 0-5 V is controlled by twin potentiometers. The two potentiometers, each of which covers the full 360', are 180* out of mechanical phase with each other. Their use in this manner climinates the crossover problem of a single unit when the wind oscillates around the crossover point. D 4

The continuous analog output voltage from this unit drives the scribe on g the analog recorder. A sample is taken by the data logger once each minute, and the digital value is entered on the magnetic tape. 2.2.2 WIND RUN The cups, through a gear train, rotate a magnet past a reed switch to produce a closure once for every O.1 mile of wind flow. Each switch closure produces a pulse which is accepted by the data logger and recorded on the tape. Each pulse also drives a side marker on the analog chart. 2.2.3 TEMPERATURE The sensor is a shielded and power-aspirated linear thermistor network which contains a resistor with a high temperature coefficient. The continuous voltage output on a scale of 0-5 V is recorded directly on the analog chart and is sampled and recorded once cach minute on the magnetic tape. 2.2.4 TEMPERATURE DIFFERENTIAL Two pairs of temperature sensors are located at the 30- and 130-ft, and one pair is located at the 30- and 230-ft 1cycls on the tower. The voltage

  . output difference between the two in each pair is amplified to a scale of 0-5 V. This amplified output is sampled and recorded in
  • C in the s ame manner as temperature.

2.2.5 RELATIVE HUMIDITY The sensing element is a xeritron fiber which changes shape as a function of relative humidity. It exerts a corresponding stress on a pair of thermally matched silicon strain gages connected as a half Wheatstone bridge. The continuous output is a voltage on a scale of 0-5 V which is recorded in the same manner as temperature. 5

2.2.6 DEW POINT TEMPERATURE This measurement is obtained by chilling a stainless steel mirror to the actual dew point. As the condensate forms on the mirror, an optical sensing bridge detects the change in the reflectance of the mirror surface. Appropriate circuitry controls the thermocicctric cooler to permit the mirror to continuously track the dew point. The dew point temperature is measured by platinum resistance thermometers. The continuous output voltage on a scale of 0-5 V is recorded directly on the analog chart and recorded once cach minute on the magnetic tape. 2.2.7 TURBULENCE (Sigma) The fluctuating voltage output of the wind-vane potentiometers is passed through a high-pass filter circuit to obtain the standard deviation of the horizontal wind direction, commonly called " sigma". The unit works according to the principles presented by Jones and Pasquill . In the 15-min mode used at the plant site, the unit outputs the 15-min running mean of standard deviations of 180 consecutive voltages sampled at 1-sec inte rvals . This is equivalent to a high-pass 3-db frequency of 0. 0055 Hz and encompasses that portion of the turbulence spectrum that is responsible for initial dispersion of effluent clouds. The voltage is converted to sigma in degrees; the scaling is 0-45

  • for 0-5 V dc.

2.2.8 PRECIPITATION Precipitation is funneled into a bucket collector which tips for each 0. 01 in. collected. This event activates a frictionless magnet reed switch which produces a contact closure and sends a pulse to the data logger and analog recorder. The pulse is recorded as a count on the magnetic tape and actuates the event marker on the analog chart to produce a step in the trace. 6

2.2.9 SOLAR RADIATION I The detector is a differential thermopile with the hot-junction receivers blackened and the cold receivers whitened. The output is a voltage on a 0-5 V s cale. It is recorded on the analog strip chart and is sampled once cach minute by the data logger and recorded on the magnetic tape. j f l Voltages are converted to units of lang1cys/ min'a] .

2. 3 CALIBRATION AND MAINTENANCE The calibration and maintenance policy and general procedures of MRI are specified in the Quality Assurance Manual, revised October 8,1973.

Detailed procedures are specified in the Quality Control, Field Operations and Data Management Departments' procedures manuals. All of them are undergoing constant review and upgrading in accordance with AEC require-ment s. Applicable portions are summarized here for purposes of this report. O

2. 3.1 CALIBRATION All sensors and related equipment are calibrated according to procedures specified in the Quality Control and Field Operations manuals. These procedures are designed to assure adherence to AEC specifications for accuracy. The first calibration is accomplished on the fully assembled system in the plant before delivery. A calibration check is made following installation. Additional calibrations are made at intervals of no greater than 6 months. At the site, full system calibrations were made on December 29,1973; March 13, June 27, September 12, and December 17-20, 1974.

Component checks, adjustments, and other procedures were carried out at other times. [a] One langicy = 1 calorie /cm8 . 7

All meters and other equipment used in calibrations are in turn calibrated

 ) at frequent intervals. All calibrated instruments used have evidence of accuracy in the historical record, which is traceabic to the National Bureau of Standards.

2.3.2 MAINTENANCE Inspection and maintenance of all equipment is accomplished in accordance with written procedures in the referenced manuals. All equipment is thoroughly inspected prior to each system calibration. Individual com-ponents are removed for servicing at intervals specified in the manual or more frequently if the need is detected. If the maintenance required cannot be accomplished at the site, the component concerned is returned to PGE's instrument shop, to MRI or, in the case of the recorder and data logger, to the manufacturer for refurbishing. In case of major troubic in the system, an MRI electronic technician or engineer is dispatched to the site on short notice to investigate and effect a cure. 2.3.3 ON-SITE MONITORING The site is visited every second day by a monitor employed by PGE. This individual checks to ascertain that all components appear to be operating properly. He is empowered to restart the system if necessary, to check and make zero-set adjustments of the analog recorders, to put ink in the pens, and to examine the analog traces for reasonableness. Procedures for these operations are posted adjacent to the recorders. Should a possible ~ malfunction be detected, he is required to notify the PGE instrument engineer immediately. 8

In addition to this routine monitoring, the site is visited approximately l 'once a week by the PGE instrument engineer. Chart and tape changes, servicing of the recorders, c1 caning of the instrument shelter, careful inspection of analog traces, and minor repairs and adjustments are accomplished during these visits. 2.3.4 DATA MONITORING All analog charts are subjected to a careful inspection for discrepancies or evidence of malfunction as soon as possible after receipt by MRI. Similarly, the magnetic tapes are immediately processed and the preliminary listing is examined.and compared with the analog values. Because a knowledge of what values to expect is required, a professional meteorologist is assigned to this task. The primary purpose of this quality control procedure is to detect signs of malfunction or the need for calibration as soon after the need arises ) as possible. When a need for servicing is detected, the PGE instrument engineer and MR1's Project Manager and Field Operations Manager are advised immediately. They then plan and execute the corrective action. The procedures for data monitoring are given in the procedures manual for the Data Management Department. They emphasize such factors as reasonableness, consistency among parameters and diurnal variations.

2. 4 DATA RECOVERY An evaluation of system performance (i. e. , percent recovery of valid data) is made following the quality check. The recovery rate for the year 1974 has averaged about 94 percent. Except for January, monthly recovery rates have averaged over 90 percent. The recovery, which is shown by parameter by month in Tabic 2-3, is now regularly over 95 percent and often over 9

99 percent. The early data loss has been attributable mostly to missing g delta T and wind run data. As indicated by the December recovery report, no significant data loss problems exist with any parameter as of the end of 1974. 9 g- % i N___./ 4 e 10

3. O PROCESSING AND ANALYSIS I

The analysis procedures used in the Pebble Springs Project are designed to obtain the most accurate data and analyses possible. They are responsive to Regulatory Guide 1. 23 and follow the guidelines provided in the AEC's Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants (Rev. 1) dated October,1972. l 3.1 DATA QUALITY CONTROL As described in Section 2. 3.4, all data are subjected to a quality check as soon after receipt as possible. The analog charts are given a detailed inspection which includes, but is not necessarily limited to, the following items : (1) Chart timing. Timing is checked to see if it matches reported on and off times and the off time of the previous chart. Chart is retimed if necessary. (2) Adherence to scale. (3) Reasonableness of data. This includes consideration of the proper diurnal variations of temperature, humidity and temperature difference; the absolute values of these and other variabics; and the relationships among variables such as wind speed, temperature and temperature difference. (4) Continuity of data and of instrument operation. (5) Evidence of power interruptions and of malfunctions. I 11

A " dump" of the magnetic tape (in voltages) is obtained as soon as possible

        , after receipt and the data are given a preliminary inspection for consistency and reasonableness and to locate any gaps. The data are then converted to engineering units, the gaps are filled by data from the analog charts, and a new dump is obtained. These data are then compared on a random sample basis with data from the analog charts.

This quality control procedure is intended to detect electronic or sensor drift or malfunction, improper mechanical zero adjustment, or other sources of error in the data. Much of the time erroneous data can be retrieved. This is usually accomplished on the basis of a recalibration and/or appropriate comparisons with data of known quality obtained under similar conditions. If valid correction factors cannot be determined, the questionable data are not used in the summaries and analyses.

3. 2 DATA REDUCTION j

Data recorded on magnetic tape consist of either voltages or impulses, and the original tape dump consists of values recorded at 1-min intervals as described in Section 2. 2.1. When these data are converted to engineering units by application of the appropriate scale factors, they are also averaged to obtain the hourly values which are then used in the analyses. Wind direction, temperature, relative humidity and temperature difference ire averaged over a 15-min period centered on the hour. Wind run is accumulated over a 1-hr period centered on the hour. Because sigma is aircady averaged, the reading at 7. 5 min past the hour is selected. Solar radiation and rainfall are summed over the previous hour. All data arc entered on the new tape as hourly values. v 12

Any reduction of analog charts that is necessary is accomplished on the Oscar S2 semiautomatic chart reader. The same averaging periods used I for digital data reduction are used for the analog data.

3. 3 ANALYSES The hourly data are compiled into a series of summary tables presented herein and discussed in Section 4. Most of these tables are produced by month, season (quarter), and year. They are used as inputs in the computation of the X/ Q estimates discussed in Section 3. 5.

Stability categories used in this report were determined by the Sigma-AT method. The value of sigma was used to determine o for use in the hourly Y y/Q calculation if wind speed exceeded 3 mph. If the wind speed was 3 mph or below, AT was used to determine a . The value of AT was 2 sed to determine o ; however, if AT wac miccing and the wind cpced wac above 3 mph, sigma was used to determine Za . The criteria for assigning obser-vations to stability categories are those specified in Regulatory Guide 1.23, as follows:

                                                                                                             ]

Stability Cat. o- Range (*) AT-Range (*C/100 m) A 2 22.5 <-1.9 B 22. 5 >o n 17. 5 - 1. 9 s AT <- 1. 7 C 17. 5 >o d 12. 5 - 1. 7 s AT <- 1. 5 l D 12.5 >o 2 7. 5 - 1. 5 s AT <-0. 5 ' E 7. 5 >o d 3.75 - 0. 5 s AT < l . 5 F 3. 75 >o a 2. 0 1. 5 s AT < 4. 0 l G o< Z.0 4. 0 s AT l The sole use of AT and the criteria given above for determining 3o stability categories leads to a distortion in the distribution of Categories A, B, m and C. When the range of AT's varies over an interval of only 0. 2 *C/100 m 13

(0. 06 *C/100 ft), as it does for Category B, and the measurements are g made with an accuracy of

  • 0.1 *C and read to the nearest 0.1 *C, it is not possibic to obtain the necessary precision. The AT-interval for Category B is -0. 52
  • to -0. 58 *C, so with a value of -0. 6
  • a is classified as A and with -0. 5* cr z is designated as C. Hence, it will be noted that the incidence of Category B in all tables presented here is very low. Were it not for the use of sigma in the absence of valid AT measure-ments, there would be no cases of Category B reported.
3. 4 DIFFUSION ESTIMATES 3.4.1 SHORT TERM (ACCIDENT) MODELS All accidental atmospheric releases from the plant are assumed to occur at ground level. Except as noted below for stable, light-wind conditions, hourly plume centerline X /O factors were calculated by means of the equation:

i x/O = 1 (sec/m8) (3 -1) n (noyz o + A/2) where X = concentrations of contaminant (units /m8 ) Q = source strength of contaminant (units /sec) n = mean wind speed (m/sec) o = crosswind standard deviation of contaminant at downwind Y dista. ice x (m) o = vertical standard deviation of contaminant at downwind z distance x (m) A = cross-sectional area of the containment = 2730 m8 14

Values for a and a corresponding to the first six stability categories Y g were determined from Meteorology and Atomic Energy (2) Those for . the seventh, Category G, were determined by extrapolation in the manner suggested by Yansky, Markee and Richter . Calms were assigned to the  ; t last recorded direction, and all wind speeds below 0.25 m/sec were l 1 assigned a speed of 0.25 m/sec. The effect of the term A/2 is limited to a factor of 3; however, checks revealed that the use of this wake factor reduced the value of x/Q by less than a factor of 3 in all cases. i 1 When stability categories E, F, or G occurred simultaneously with wind speeds of 2. 5 mph or less, allowance was made for meander by using the equation:

                                    =

X/Q 1 (3 -2 ) L (4 w yz e c + A/2)

  )

where the effect of A/2 was limited to a factor of three. Precedent for the use of this equation for stable, light wind situations was set in the recent River Bend case. Justifications for its use were provided in the recent PSAR, and will not be reiterated here. The " window" model suggested by Woodard was used to compute sector averaged atmospheric dispersion factors for time periods of 8 hr, 16 hr, 3 days and 26 days. Cumulative frequency distributions were determined for each sector following computation of the average X/Q for each

    " window" period by the equation:

4.O DISCUSSION I 4.1 WINDS 4.1. I WIND ROSES Monthly and seasonal joint frequency distributions of wind directions and speeds (commonly referred to as " wind roses") are given for the three IcVels (30, 13 0, and 23 0 ft). The pertinent features of these tables and figures are as follows: (1) The prevailing wind is parallel to the river, i. c. , from the west at all . levels. This flow is in general agreement with that observed at Arlington, the old Boardman Test Tower, and the Carty West tower. All reficct the influence of terrain which is otrongest in spring and summer and weakest in autumn. (2) The incidence of low wind speeds (s 0. 5 m/sec) varies from , zero in summer to 1. 5 percent in the fall and is very low over-all. Speeds less than or equal to 1.0 m/sec occur 8.6 percent of the time annually and vary from 3.4 percent in the spring to 18.4 percent in the fall. (3) The secondary maximum in wind direction is from the cast-northeast and is about equivalent in frequency at all levels. There is, however, little evidence of the shallow drainage winds such as that observed at the Carty West site. The tendency for light winds during stable conditions to occur from the southwest suggests a deep drainage wind off the east slope of the cascades. O 18

(4) The direction of the primary westerly flow tends to remain fairly constant with height. The occurrence of stronger I wind speeds increases with height, as expected. The annual joint distributions by stability category " show a frequency maximum of winds from the southwest during Category G conditions. Characteristic speeds under these conditions are 0. 5 to 2 m/sec. Wind flows for categories A through E differ very littic from the overall distribu-tion's . 4.1. 2 WIND DIRECTION PERSISTENCE The persistence of wind directions is given on a seasonal and annual basis for the three tower Icvels. The most persistent winds are the prevailing winds from the west. These winds also tend to be the strongest. At 30 ft, percistence of 3 hr or mere occurs about 18 percent of the time and 5 hr or more about 10 percent of the time with westerly winds. About 8 percent of all cases last 3 hr or more. The maximum number of consecutive hours recorded for west and southwest winds was 20 hr.

4. 2 STABILITY 4.2.1 MONTHLY DISTRIBUTION OF STABILITY CATEGORIES Tables of monthly, seasonal, and annual percent frequencies of occurrence of the various stability categories measured on the tower show a tendency for Categories D and E to prevail. The first three inversion categories indicated on the Percent Frequency of Occurrence of Stability Categories Table are incorrect because of problems with the 30-130 ft AT and because the computer is programmed to use this AT for inversion determination.

Frequencies based on the 30-230 ft AT are added to the bottom of the Table. [a] The lack of cases in Category B is explained in Section 3.3. 19

Another basic feature exhibited in this table is that fall and winter months g show a greater prevalence of stable conditions than do spring and summer. 4.2.2 DIURNAL STABILITY CATEGORY DISTRIBUTION Tables of the variation of stability category distribution with time of day exhibit a clear tendency for Categories E and G to prevail during evening, night, and morning hours and for Categories D and A to be favored during the daytime. Because windiness produces mixing and thereby favors near neutral temperature stratifications, it appears that this tendency for Categories D and E to prevail reficcts the characteristic windiness of the area. On days with low wind speeds, the favored stability Category is A in daytime and G at night. 4.2.3 STABILITY CATEGORY DISTRIBUTION BY WIND DIRECTION A comparison of th2 annual 30' wind roses by stability category demonstrates the tendency for the prevailing westerly winds to be in Category E and the night southwesterly drainage winds to be in Category G. Most south-westerly winds occur with Categories F and G. Wind speeds with these stable conditions tend to range from 0. 5 to 5 m/sec. 4.2.4 STABILITY PERSISTENCE It is apparent in the tables of persistence of the seven stability categories v that Category E is the most persistent. Twenty-one percent of the occurrences lasted 5 hr or longer and one lasted 37 hr. About 10 percent of Category G occurrences lasted 8 hr or more and several persisted 14 to 15 hr. It is recognized that persistence of stable conditions, such as F and G combined, is likely as great as great as that for an E category. I 20 b

4. 3 DIFFUSION ESTIMATES h 4. 3.1 HOURLY VALUES The seasonal and annual cumulative frequency distributions of hourly X /O class intervals were computed for 800 m, 3200 m, and the distances to the actual site boundaries by means of Equation 3-1. The 5- and 50-percent X/O values and the worst conditions are given for each. The v

worst condition is defined here as the highest single hourly X/O computed for that distance. The critical 5-percent value at the exclusion distance is 3. 821 x 104 4.3.2 OTHER SHORT 3ERM VALUES Cumulative frequency distributions of average X/Q class intervals at

                                    ~

800 m and 3200 m by direction sector were computed annually by means of the window model (Equation 3-3) for 8 hr, 16 hr, 3 days, and 26 days. Also given in each table are the 5- and 50-percent levels and the worst conditions. The worst condition is considered to be the highest X/Q value computed for any window. The maximum column on the extreme right lists the highest frequencies reported for any direction for these concentrations. They are intended to help define the envelope of worst conditions. N The 5- and 50-percent values for each of the window periods and for the hourlies are presented as a function of distance in another table. 4.3.3 ANNUAL AVERAGE The annual average x/Q's computed by Equation 3-4, for each sector at dista.xes ranging from O. I mile to 50 miles are presented as the final X/Q table. The highest values - for winds from the southwest th-ough west-reflect either the stable flow, or the high frequency of occurrence of winds from those directions. I 21
