SUMMARY

Duke Power Company contracted Acoustic Technology, Inc. (ATI) to verify and field test the acoustic coverage of the siren notification system installed within the plume exposure pathway Emergency Planning Zone (EPZ) of the Catawba Nuclear. Station. This study documents the adequacy of the warning system in meeting the guidelines set forth in the Federal Emergency Management Agency's (FEMA's) regulations 44 CFR 350 Planning Standard E, Appendix 3 of NUREG-0654/ FEMA REP-1, and the The Standard Guide for the Evaluation of Alert and Notification Systems for Nuclear Power Plants (FEMA-43): Scotember 1983.

The Catawba Nuclear Station siren system was designed by the Utility based on the above FEMA guidelines. The ATI analysis, based on a computer model, is somewhat more conservative than the system original design basis due primarily to the following factors:

1. Method of determining attenuation factors (ATI uses a computer model, the Utility design basis used an attenuation factor of 10 dB per distance doubled).

2. Method of determining ambient background noise (ATI uses a 50 or 60 dB ambient based on population density studies and actual field measured ambient, the Utility design basis used 50 or 60 c8 ambient based on population density studies).

Acousnc TECHNOL.OGY INC.

3. Application of cost / benefit evaluation for marginal coverage areas was considered only in the Utility design basis.

The warning system design includes 66 high-power rotational sirens, rated 125 dBC at 100 feet,'and one siren rated 113 det at 100 feet. Verification of the acoustic coverage for the siren warning system was accomplished by using a computer model developed by ATI, and field measurements of sound levels. The actual measured siren output at 100 feet, obtained through field testing for a sample number of sirens, was used to predict the extent of the 60 and 70 cBC acoustic coverage of the siren system for daytime summer average meteorological conditions. Predicted siren sound pressure Level (SPL) values for each measuring location were obtained f rom the ATI acoustic computer model. The predicted and measured siren SPL's were in excellent agreement, and the ATI computer model calculated slightly conservative predictions of siren acoustic coverage.

Map 1 shows the composite acoustic coverage of the 60 and 70 dBC siren alert signal of the entire system with 67 high power sirens, which is based on the siren data obtained f rom the actual siren testing. The 60 and 70 d8C coverage for the installed sirens was evaluated based on the demographic distribution and ambient sound environments within the EPI, to determine if essentially 100 percent of the population receives adequate alert coverage.

According to FEMA-43, the siren alerting system may be designed so that the siren sound level either exceeds 10 dB above the average outdoor daytime ambient sound levels, or provides 60/70 d8C acoustic alert coverage Acoustic TECHNOLOGY lNC.

depending upon the population density of the area. An ambient background noise survey was conducted within the 10-mile EPZ to document the average measured outdoor ambient sound level in specific areas located outside 60 dBC siren acoustic contours. Based on the ambient noise survey, the average ambient sound level for each area outside 60 dBC contours was determined. Map 2 indicates the regi,ons outside of the 60 dBC coverage with the 50 dBC acoustic coverage contours plotted for each siren location.

Accordingly, it was determined that the installed siren warning system is in compliance with FEMA-43 guidelines to alert the public within most areas of the 10-mile EPZ of Catawba Nuclear Station. Consideration of additional coverage for portions of the regions identified in Section 8.0 as being outside of 50 d8 coverage wiLL bring the Catawba system into full compliance with FEMA-43 in att EPZ areas.

1.0 INTRODUCTION

The nuclear accident at Three Mile Island (TMI) emphasized the need for better emergency preparedness procedures for commercial nuclear power plant Licensees and for state and local of ficials who would be responsible for alerting the public in the event of a general nuclear emergency. In October 1980, the Nuclear Regulatory Commission (NRC) and FEMA issued a document entitled Criteria for Preparation and Evalutaion of Radiological Emergency Response Plans and Precaredness in Support of Nucle 4r Power Plants (NUREG-0654, FEMA-REP-1). Among other things, this document lists the criteria for prompt notification of the public in the event of a general nuclear plant emergency. These criteria are presented in NUREG-0654, Appendix 3: "Means for Providing Prompt Alerting and Notification of Response Organizations and the Population."

The final legislation regarding pronpt notification was published in the Federal Register which defines the requirements as follows: "The nuclear power reactor licensee shall demonstrate that administrative and physical means have been established for alerting and providing prompt instructions to the public within the plume exposure pathway Emergency Planning Zone (EPZ). The design objective shall be to have the capability to essentially complete the initial notification of the public within the plume exposure pathway EPZ within about 15 minutes."

Documentation of the system design coverage is required as stated in FEMA-43. ATI was ccntracted by Duke Power Company to independently

-1 E Y k.

W evaluate and* document the acoustic coverage of the installed siren alert notification system of Catawba Nuclear Station. This system consists of 66 Federal Signal Corporation (FSC) Thunderbolt sirens and one FSC STH108 i siren.

The design objective of the installed siren system is to provide a full acoustic coverage for the populated sections of the Catawba Nuclear Station EPZ, in compliance with FEMA /NRC regulations. FEMA-43 states that for an adequate siren system, the expected siren sound level should exceed 70 d8C where the population density exceeds 2000 persons per square mile and 60 d8C in other inhabited areas. Alternatively, the siren sound level coverage should exceed the average measured daytime ambient sound level by 10 dB.

In February 1984, a team of ATI consultants and engineers conducted field testing for a sample number of sirens and performed an ambient background noise survey to determine the average measured outdoor daytime ambient sound level within the 10-mile EPI. The field test program for the siren system included:

1. Evaluation of siren sound pressure level output at 100 feet.

2. The Siren System Acoustic Performance Test, consisting of:

a. A determination of the sirens' propagation range,

b. Validation of the acoustic coefficients of sound propagation, and

c. Verification of acoustic coverage.

_2 OAcousTic TECHNOLOG

Siren sound Revel measurements were made for a representative, randomly selected sample of six sirens. This sample size was determined to provide at least a 95 percent confidence interval with the assumption of a 2 dB level of accuracy for average siren output. ATI's test engineers, assisted by personnel from Duke Power Company performed the sound level measQrements using acoustic instrumentation which conforms to standaros set Dy the American National Standards Institute (ANSI). Sound level meters were calibrated both before and after testing in accordance with ANSI procedures. Siren sound pressure levels, ambient background noise levels, and meteorological conditions were noted at each of the measurement locations for each siren activation. Locations for field measurements were selected on the basis of site specific conditions for each installed siren, and varied depending on f actors such as road accessibility and how many times the siren was activated.

According to FEMA-43 criteria, the 60 d8C and 70 dBC acoustic coverage contours of the installed siren systems have been obtained by using the ATI computer model (See Appendix 1). These sound contours were superimposed on the United States Geological Survey (USGS) map of the 10-mile EPZ, and are presented on Map 1. Daytime sumaer average weather conditions were used for this analysis. Map 2 illustrates areas which are located outside 60 d8C acoustic contours.

As part of the verification of the acoustic coverage of the siren alerting i i

system for the Catawba Nuclear Station, an ambient background noise survey was also conducted to determine the average measured outdoor daytime i

ambient sound level. The areas outside of the 60 d8C siren sound coverage contours were surveyed to establish accurate daytime ambient sound levels to ensure adequate acoustic coverage. The measuring locations for the survey are also indicated on Map 2.

By oetermining the average outdoor daytime ambient sound levels, a siren signal that is 10 dB above these ambient sound levels can be determined to satisfy FEMA-43 criteria. The siren signal acoustic coverage of the installed siren warning system was evaluated based on these actual measured ambient sound levels. Most areas outside the 60 dBC siren sound coverage contours were adequately covered by the existing siren sound coverage.

2.0 EVALLTATION OF CATAW8A STATION EPZ 2.1 TOPOGRAPHIC CONSIDERATIONS As recommended in FEMA-43, USGS topographic maps were used during the analysis process. The plume exposure pathway EPZ of Catawba Station includes a composite of nine USGS topographic map quadrangles of foot scale 1:24,000. An index of the topographic map quadrangles used for this analysis with Latitude and Longitude indications is shown in Figure 1. Two of the map quadrangles, Clover and Rock Hill West, are not currently available in the 1:24,000 scale. Therefore, 1:62,500 scale maps for the area were enlarged to fit the scale of the other EPZ maps. Land elevations and ground conditions were read directly f rom the USGS maps as input into i

the computer analysis for sound propagation to ensure accurate predictions.

Catawba Nuclear Station is located on the shores of Lake Wylie in York County, South Carolina. The surrounding area is predominantly rural and is characterized by gently rolling hills, which are mainly tree covered. The Catawba site elevation is approximately 600 feet above mean sea level (msL). Land elevations within the EPZ range from 600 feet mst to 750 feet mst. At a typical siren location, changes in elevation for the sound propagation area vary 30 to 90 feet, with the average difference of 50 to 60 feet between the highest and lowest points along a sound propagation

- path. Therefore, relatively significant topographical features of the EPZ must be considered in the calculation of sound attenuation over Long distances.

OAcoustic TECHNOLOG

2.2 DEM05RAPHIC DISTRIBUTION Three counties, York County, South Carolina (SC), Gaston County, and Mecklenburg County, North Carolina (NC) are located within the EPZ of Catawba Nuclear Station. Based on the 1980 Population Census, there is a total population of approximately 93,000 persons within the Catawba EPZ.

Significant population groups within the 10-mile EPZ are located in Rock HILL, SC; York, SC; Fort MILL, SC; and Clover, SC. The population and Land area for these areas were evaluated by Duke Power Company to determine their population density. FEMA-43 guidelines indicate that areas where the population exceeds 2,000 persons per square mile should be covered by a louder siren signal. Based on this evaluation, Rock HILL, Fort MILL, and Clover have areas where the population density exceeds 2,000 persons per square mile. These areas are shown on Map 1.

2.3 METEOROLOGICAL CONSIDERATIONS FEMA-43 guidelines suggest that average summer daytime weather conditions be used to calculate siren sound contours. To determine these conditions, excerpts from Section 2.3 of Catawba Nuclear Stations's Final Safety Analysis Report (FSAR) relating to meteorology were evaluated to assess levels of temperature, relative humidity, wind speed and direction. The source of this data is the Douglas Municipal Airport in Charlotte, NC.

o Temperature The monthly average temperature variation of the Catawba Nuclear Station climatology ranges f rom 42.1 0 F in January to 78.5# F in !

July with a yearly average of 60.5*F. These monthly temperatures were calculated as an average of the daily maximum and daily minimum temperature. It is recognized that this average monthly temperature is not a true " daytime" average as requested in FEMA-43. However, for the purpose of design analysis, these averages provide a good indication of the daytime average.

Therefore, to determine the average summer weather conditions, the monthly temperatures for June (75.9 F), July (78.5 F) and i

August (77.7 F) were averaged. As a result, the average summer temperature is calculated to be 77.4 F.

o Relative Humidity:

The relative humidity for the site was derived by evaluating the monthly mean dewpoints for June, July, and August with respect to the monthly temperature. The derived relative humidities for June, July, and August are 50 percent, 54 percent and 58 percent, respectively. The average summer relative humidity was calculated to be 54 percent.

o Wind Speed and Direction:

The highest mean wind speed for the Catawba Nuclear Station vicinity is 8.9 mph in the months of March and April. The mean

~

wind speed is 7 mph in June, 6.6 mph in July, and 6.5 mph in August. Therefore, the average summer mean wind speed is 6.7

_ mph. The prevailing wind directions for the Catawba vicinity during June, July, and August are Southwest, Southwest, and South 1

1 respectively. Therefore, the average dominant wind direction in the summer is determined to be the Southwest.

Based on this evaluation, the following average summer meteorological conditions were used in the computer analysis for the siren sound coverage:

3.0 SIREW AC0USTIC COMPUTER MODEL The siren sound levels within Catawba Nuclear Station plume exposure EPZ were calculated using a computer model developed by ATI. The computer model considers meteorological factors, topographical factors, and Land surface conditions. These factors affect the propagation of the acoustic signal generated by a siren.

The results of the analyses for each siren location are presented in Appendix ta. From these results, the 60 and 70 d8C contours have been plotted for each siren location. These siren sound contours are presented in Appendix 1b and have been plotted to the scale of the USGS maps for the EPI. The various f actors considered in the sound propagation analysis by the computer model are summarized as follows:

A. Hemispherical Wave Divergence The change in sound pressure level from hemispherical divergence is uniform in all directions and occurs at a rate of 6 dB per doubling of distance from the sound source. This non-dissipative sound pressure level attenuation is a result of the decrease in energy density (energy per unit area) of the propagating sound wave. The energy density of a sound wave decreases as the distance f rom a sound source increases because of the increase in the surface area over which the constant energy of the wave is distributed.

B. Atmospheric Absorption Molecular absorption further reduces the sound energy. ,,T h i s

_,_ Acoustic TECHNOLOGY INC.

dissip4tive sound level attenuation is f rom inelastic collisions of air molecules. Absorption is highly dependent on the temperature and the relative humidity of the air, and is quite pronounced at long distances and at high frequencies.

C. Ground Effects Sound attenuation is a function of the ground cover and the siren's height. The ground cover conditions were read directly from USGS maps at various directions and distances from the installed siren locations. These conditions were used to calculate the sound attenuation due to the absorptive effect of the different ground 1

coverings.

The primary path of outdoor sound propagation is the direct line-of-sight path; the secondary path is the ground reflected path.

Both of these paths are subject to sound attenuation due to the effect of ground cover between the sound source and distant locations.

In general, five types of ground cover are distinguishable from USGS maps for evaluation by the ATI computer model:

1. Dense vegetation - forests, mangrove, and thick brush attenuate sound to the greatest extent.

2. Wooded marsh - Vegetation attenuates sound, but water reflects sound to a certain extent, so attenuation by this ground cover is not as great as that by denser vegetation.

Accuenc TaCHNOU3GY INC.

d

3. Water, marshes - Water acts as a reflector for sound propagation so attenuaton over water is very slight.

4 Open fields - Where there is no dense vegetation or other barriers to sound, attenuaton is slight.

5. Urban and suburban areas - Sound reflects weLL from pavement at acute incidence angles. Sound is attenuated to a significant extent, however, in urban areas close to the siren; buildings act as sound barriers and reflection is poor because of high incidence angles. In urban areas further away from the siren, sound propagates with a low attenuation rate as a result of increased reflection due to the lowered angle of incidence.

Within the EPZ of the Catawba Station, the typical ground features are dense vegetation and open field. Also, several urban and suburban areas exist which are considered in the computer analysis.

D. Wind Shadows Wind gradients near the ground are usually positive; that is, wind speed increases with height. As a result, a wind shadow zone is most commonly encountered upwind of a siren because headwinds with positive wind gradients bend sound rays upward. Downwind, the sound rays are bent downward and no shadow zone is produced. Crosswind, there is a zone of transition.

ACQUSTIC TECHNOLOGY lNC.

I I

E. BarrierhttenuationEffects A mound of earth, a hill, or a structure, if large enough, are partial barriers to sound and can reduce sound levels within their shadow zone. The sound attenuation caused by a barrier is estimated by tne computer model.

The computer model determines the effective barrier height which is the height above the line-of-sight from the siren to the receiver location. The other two essential dimensions are the distance f rom the siren to the barrier, and the distance from the barrier to the receiver. These dimensions are used to calculate the attenuation of sound from the barriers. Topographical data from USGS maps are used to calculate the sound atten_ation from barrier effects caused by the high elevations generatk.g acoustic shadow zones behind ridges and hills.

F. Siren Characteristics Another factor considered by the ATI computer model is the siren type.

The Catawba Nuclear Station alert system uses two types of sirens:

the FSC Thunderbolt 10008 and the FSC STH108. The computer analysis used siren sound outputs of 125 dBC at 100 feet for the FSC Thunderbolt, and 113 d8C at 100 feet for STH108 to generate the 60 and 70 dBC sound contours. The siren fundamental tone frequency used in the analysis was in the 500 Hz octave band. Justification for these siren outputs was based on manufacturer's specifications and field testing of these sirens conducted by ATI.

4.0 FIELI VERIFICATION OF SIREN ACOUSTIC COVERAGE 4.1 INSTRUMENTATION AND PROCEDURES FOR SIREN TESTING ALL instruments used for the siren testing comply with tha standards set forth by ANSI. The instruments were battery operated and portable. The sound level meters used in the field include Bruel & Kjaer (B&K) 2215, 2218, 2219, and 2230 meters, which are Type 1 meters and comply with ANSI S1.4-1983 (Specifications for Sound Level Meters). ALL sound filters used (octave, and one-third octave filter sets) comply with ANSI S1.11-1966 specifications.

Four high precision instrumentation tape recorders were used to collect and store the siren signals and ambient sound levels at various measurement sites for later detailed Laboratory analysis and evaluation. This procedure was useful in the verification of siren tone frequencies and siren tone effectiveness in far-field sound propagation, and the documentation of ambient sound levels. The recorders comply with ANSI /SAE J184a (Qualifying a Sound Data Acquisition System).

At the beginning of each test day, all sound Level meters were battery checked and calibrated with a B&K 4230 calibrator (accuracy + .2 dB). A calibration tone was recorded at the beginning and the end of each recorded tape. ALL recording adjustments made during each test were noted on the tape. At the end of the day, all sound level meters were checked and calibrated again. Any variance f rom proper calibration was noteo and the

-14 ACOUSTIC TECHNOLOGY INC.

appropriate corrections were made to the data. This procedure was folLowed i

in compliance with ANSI S1.10-1966 (Calibration of Microphones).

The choice of measuring locations for the siren testing was made after considering several factors. Practical considerations, for instance, restricted aLL Locations to those accessible by automobile. To fully test the accuracy of ATI's computer ' predictions, a set of measuring locations was selected at various angles and distances from each siren tested. These points were also selected to sample ground cover and vegetation representative of the propagation area of each siren, and to be easily identified on USGS maps (intersections, sharp bends in the road, etc., were preferred). Typical distances f rom measuring locations to the siren were in the range of 2,000 to 10,000 feet These distances roughly correspond to average 90 and 55 d8C contours for the siren sites. It can be safety assumed t h .* t any areas closer than 2,000 feet wiLL be satisfactorily covered by the siren sound signal. The measurement locations for each of the sirens tested are given in Appendix 2.

At each measurement location, all sound level meters were positioned to face in the cirection of the siren being tested. Sound Level meters were

held at least four feet above the ground and six feet away from any reflective surf ace (such as a fence or a building). Each microphone was fitted with a windscreen to reduce error caused by wind noise. The J

measurement procedure followed by the test engineers was in compliance with ANSI S1.13-1971 (Method for Measurement of Sound Pressure Level) standards.

ACQUsnc TECHNOLOGY lNC.

For each siren test measuring location, a written description of the site acoustic path, nearby background noise sources, and the quality of the siren signal were noted to aid in the processing and analysis of the data.

At each location, the instantaneous, direct measurement of an ambient sound level was conducted before each activation. This procedure was followed to determine the validity of the siren signal level data. If the measured siren sound level is close to the ambient sound level, for instance, the observed meter reading of the siren signal may be influenced by the high ambient sound level.

In addition to the direct measurements, 1 to 3 minute samples of siren signal and ambient background noise were recorded at selected measuring locations to enable frequency analysis of the siren tone frequencies.

Generally six or seven measuring t,ocations were predetermined for each siren activation. Since each siren was activated 2 to 6 times, a total of 14 to 38 measuring locations were specified for each siren site. The duration of each activation (2 to 3 minutes) was sufficient to allow 4 to 7 revolutions of the rotating siren horn.

The team of test engineers was taken by car to the first set of locations.

Af ter measurements were made for the first activation of the siren, the engineers were picked up and dropped of f at a dif ferent set of locations where measurements were made during the next activation of the siren. The $

engineers were then picked up and transported to the next set of locations where the procedure was repeated.

Acousnc TECHNOLOGY lNC.

I Because of the long distances involved, walkie-talkies using the utility's FM communication radio system were used to confirm that the test engineers were prepared for a siren activation. The siren was activated manually i

i from the siren control bon by Duke Power Company Personnel. l One ATI test engineer remained in close proximity of the siren to make l l additional measurements. The engineer was elevated by a bucket truck to I the height even with the centerline of the siren horn, and at a distance of 100 feet from the steen pole. Measurements were made and recorded in this manner for all sin tested sirens; to verify the siren sound output rating, and to record data to be used for narrow band .f requency analysis of the siren signal.

4.2 DATA REDUCTION AND ANALYSIS 4.2.1 Siren Narrow Bind Frequency Analysis l I i Six FSC Thunderbolt sirens of the 67 installed sirens in the Catawba Prompt Notification System were randomly selected to evaluate the acoustic performance of the system. Near-field measurements were made to determine the sound output at 100 feet from each tested siren. Far-field measurements were made to establish the accuracy of the computer predicted sound coverage of each tested siren. In addition, narrow band f recuency analyses were performed on both near-and far-field siren signal data tot t

i In medition to determining the acoustical characteristics of the tested I

strens, near- and far-field narrow band spectra were compared to study the effects of attenuation factors on far-field sound propagation. For 1

i illustrative purposes, near- and far-field narrow band analyses for a l representative stren (Stren 22) are shown in Figures 2 and 3, respectively.

l As shown in Figures 2 and 3, the higher harmonics contribute less to the  !

total SPL at large distances from the siren, since the relative amplitudes l

l of these harmonics are substantialty attenuated at long distances. This effect is f rom the atmospheric attenuation of the higher f requencies, an effect which increases with distance.

l It should be noted that far-field sound propagation is dependent on stren i signal fundamental frequency. The higher the fundamental frequency, the greater the sound propagation loss wiLL be. To illustrate this effect, the j following table is provided.

The third column Lists calculated values for atmospheric attenuation losses i

l l

for siren signal propagation at 5,000 f eet (assuming the meteorological conditions under which the testing was conducted). Attenuating factors other than atmospheric absorption are relatively frequency independent, and affect all harmonics equally. Since atmospheric absorption is the dominant attenuating factor of the higher frequencies, it is considered here for

-omparison and evaluation purposes.

The table shows that, on the average, the SPL of the siren signal's fundamental tone is substantially greater than that of all its higher harmonics, and would also be the least attenuated by the atmosphere. It 6 3uld be expected that this frequency will be the dominant tone at greater distances. Examination of Figures 2 and 3 illustrates this concept. For example, the difference in amplitude between the fundamental and its first harmonic in the near-field of Siren 22 (100 feet from siren) is about 9 c8, while in the far-field (9,000 feet) this difference increases to almost 18 c8. The far-field measurements show that the SPL of the fundamental tone of each siren tested was considsrably greater than that of its higher harmonics.

4.2.2 Siren Signal-Time variation Recordings of the variation of siren signal SPL with respect to time were made for the tested sirens. All of these measurements were made at the centerline height of the siren projector, at a distance of 100 feet. The results are presented in Appendix 4. In addition, the variation of siren j signal SPL vs time for siren 22, a typical case, is shown in Figure 4. The Acoustic TECHNOLOGnf INC.

peak levels attained by the tested sirens ranged f rom 126 to 128 dBC. As can be seen from this figure, the time history curve of the FSC Thunderbolt siren is a periodic shape with maximum SPL when the siren is facing the measuring microphone.

The graphic level recordings shown in Appendix 4 also indicate that the FSC Thunderbolt sirens tested completed one revolution cycle in 25 to 26 seconds, with a corresponding rotation rate of 2.3 to 2.4 rpm. However, it should be noted that Duke Power Company will configure the system to operate at the 4 rpm siren rotation mode.

l 5.0 COMPMISON OF FIELD TEST RESULTS WITH PREDICTED VALUES For purposes of comparison with the actual siren SPL measurements, corrections for meteorological conditions and the d8C to dBA conversion were made to the computer predicted SPL values. The data summary tables in Appendix 5 include temperature, relative humidity, wind speed and direction for the day, and the time of each individual siren test. Hourly reports of the ambient temperature, relative humidity, and wind conditions for each test day were obtained from the National Weather Service of fice at the Douglas Airport in Charlotte, NC. Subsequently, ATI's computer model was used to predict siren sound levels based on the specific meteorological conditions recorded during the siren tests. - Fu r t h e r, for each , tested siren, the sound level output and siren fundamental tone frequency measured at 100 feet from the siren were used as input parameters for ATI's computer model.

To compare the measured siren field test results to the analytically predicted sound pressure level values, a statistical analysis of the differences was performed. To ensure the accuracy of this analysis, the only field measurements used were those which were not unduly influenced by local effects. Measurement data values were not considered in comparison between measurements and predicted values, if they were affected by any of the eight following conditions:

1. An acoustic barrier ef fect caused by large distant buildings, structures, or topographical features which shielded the receiver from the siren signal.

2. A. Local shadow-zone: nearby homes or other structures which acted as an acoustic barrier, e.g. the test engineer may have been located behind a house, a small hill, etc.

3. A sudden and sporadic wind or atmospheric effect causing a large variation of the siren signal.

4 Disagreement due to factors not shown on USGS maps.

5. Interference of an audible siren signal by passing traffic.

6. Failure of a siren signal to register above the ambient noise level.

7. Equipmen'. or human error, e.g. weak batteries, incorrect meter read;r.gs, etc.

8. Increase in a measured level due to reflection from surrounding topography (hills, mountains, etc.).

Conditions which typically af f ected the field measurement data during the Catawba siren testing were factors 4, 6, and 8. A histogram depicting the differences between the predicted and the measured SPL for the tested s.i rens, along with the average and the standard deviation,, is given in Figure 5. The average dif f erence between the predicted and measured SPL values is -0.53 dB. This indicates an excellent correlation between the 1

l

, i computer model anc the actual field measurements. It should also be noted that the negative value for the average indicates slightly conservative predicted values. Since -0.53 cB is less than the precision of the sound level meter (1 1 dB), it can be concluded that the computer model is a very accurate prediction method. The standard deviation, which is a measure of the typical fluctuation of the test values about the predicted values, was calculated to be 1.9 dB.

A plot of the differences between predicted and measured SPL values vs distance f rom the siren is shown in Figure 6. Eighty-nine percent of all differences are within 1 3 dB of perfect agreement, once again showing the good predictive ability of the computer model. Since the 60 dBC contour usually occurs at distances in the range of 6,000 to 8,000 feet from the siren, this portion of the plot should be considered. Most distances further than 6,500 feet show measured values greater than the predicted values, once more indicating the conservative nature of predictions at large distances from the siren.

It should be noted that since the fundamental tore frequency of the tested sirens was around 660 Hz, this parameter was used as input to ATI's computer model to compare field test results with predicted values. The acoustic coverage and alert effectiveness of these sirens may be increased by adjusting the sirens to produce a slightly lower fundamental frequency (575 Hz). However, the accuracy and conservative nature of the model will l

remain, regardless of the frequency adjustment that is selected, within the optimum range.

6.0 AMBIENT BACKGROUND NOISE SURVEY The 79 measuring locations for the ambient background noise survey were selected through an extensive preparation and field investigation process.

Since the primary interest of the ambient background noise survey was placed on the areas outside the 60 d8C siren acoustic coverage, measuring locations were chosen in these areas, as shown on Map 2. As described in FEMA-43, factors considered in evaluating the ambient sound level in these areas included population density, effects of major transportation rGutes, and effects of commercial / industrial activities.

For each location, the overall ambient sound pressure levels were measured.

These included measurements made with A weighting, and in one-third octave bands containing the predominant tones of typical sirens. The background noise sources affecting the reading and a brief description of the measuring locations were noted. These data are presented in Apper.oix 6.

Table 1 presents a summary of the dBA, 500 Hz, and 630 Hz one-third octave band direct measurements made for each location. These measurements are in accordance with the procedures recommended in the FEMA-43 Standard Guide.

In addition to direct measurements, Nagra IV-SJ and Nagra IV-SN instrumentation tape recorders were used to record the ambient sound environment at each location for further laboratory analysis. Recordings made for analysis were approximately 1 to 3 minutes in length, depending on the characteristics and variability of the ambient noise. A calibration tone was recorded at the beginning and end of each tape, and all recording ACOUSTIC TECHNOLOGY lNC.

1 I

adjustments were noted. At the end of the surveying day, all recording equipment was checked and calibrated again. Any variance from proper calibration was noted and the appropriate corrections were made to the data. This . procedure was followed in compliance with ANSI S1.10-1966 (Calibration of Microphones). The recording system set up was in compliance with ANSI /SAEJ184 (Qualifying a Sound Data Acquisition System).

Since the ambient sound level at a location may vary greatly with time, it is necessary to give a statistical description of the variation. To accomplish this, a B&K 4426 Noise Level Analyzer was used to sample the sound level 10-times per second for the duration of each recorced measurement. By using linear response recorded tapes, it was possible to filter for C-weighted, A weighted, or various one-third octave bands and derive the statistical information. Since the signal frequency of'the FSC Thunderbolt sirens tested f alls within the range of 561 Hz to 671 Hz, this sampling procedure was performed for the 630 Hz one-third octave bar.c f requency and with A-weighting to reveal overall levels. Results of these analyses were obtained through a B&K Type 2312 Alphanumeric Printer. A summary of the data obtained is presented in Table 2.

To f acilitate understanding of ambient noise sources, a B&K 2031 Narrow Band Spectrum Analyzer was used. The analyzer produces a narrow band frequency spectrum, with frequency plotted vs amplituce. Knowledge of the i

ambient sound frequency spectra can ensure the dominance ,of the siren ciscreet tone over the ambient sound at the siren signal frequency.

l 6.1 AMBIENT SOUND FREQUENCY CHARACTERISTICS To better understand the nature of the ambient sound environment within the 10-mile EPZ of Catawba Nuclear Station, it is necessary to consider ambient sound frequency characteristics. These characteristics can be described in terms of standard weighting and filtering schemes, such as C-and A-weighting, and one-third octave band filtering. The usefulness of each weighting scheme (cBC, dB A) depends upon the f requencies of interest, as each scheme places emphasis upon certain frequencies and de-emphasizes others.

The overall SPL at a given point is the logarithm.ic addition of SPLs at all frequencies. C weighting serves to de-emphasize the extreme L.ow (<50 Hz) and high (>5,000 Hz) frequencies slightly while retaining the equal emphasis on middle frequencies, as shown in Figure 7. The A-weighting scheme was developed to approximate the frequency response of the human ear, which cannot perceive low or high frequency noise as well as it does noise in the middle frequencies (see Figure 7) . Since A-weighting approximates human sensitivity, it is very useful in assessing the annoyance aspects of noise.

One-third octave band , measurements consider only those f requencies which are within a one-third octave around a certain center frequency. Thus, the 630 Hz one-third octave band considers only that sound with frequencies e

between 562 and 70S Hz. One-third octave band filtering is useful when 3

AC(XJSTc TECHNOL.OGY INC.

1 only certain frequencies are of interest, such as those near the siren signal frequency.

Figure 8 shows the relationship between the one-third octave band SPLs and overall SPL as expressed in dBC. As an example, the one-third octave band frequency spectrum from 0 to 2,000 Hz of a typical ambient sound level in a rural area has been olotted in d8C. The logarithmic addition of all the SPLs of frequency bands from 31 Hz to 2,000 Hz yields an overall sound pressure level of 52 d8C. As shown in Figure 8, the recommended frequency range for siren tones is 400 to 800 Hz. A characteristic spectrum for an ambient sound level shows dB levels of 34, 35, 36, and 37 for the recommended siren f requencies of 400 to 800 Hz. These dB levels at the one-third octave band of the predominant siren tones are substantially lower than the overall level, since the logarithmic sum of all bands must equal 52 d8C.

6.2 AMBIENT SOUND VARIATION WITH TIME Background ambient sound levels vary with time. In the case of a steady noise source, this variation may be slight. More often, however, ambient conditions are changing at a measuring location, and therefore overall one-third octave band noise levels may change. Ambient sound level as a function of time for a location with typical traffic activities is shown in . Figure 9. The dashed curve shows the continuous variation of C weighted values which increase and decrease as motor vehicles pass by the AcOusnc TECHNOLOGY lNC.

] measuring location. The solid curve represents the variation of the A-weighted noise level with time, and the third curve shows the noise t:

variation at the 500 Hz one-third octave band. As described previously, C weighting takes almost equally all frequencies into account while A-weighting de-emphasizes the lower and higher f requencies. At any point in time, therefore, the dBC value will be greater than or equal to the dBA 4 value. In addition, each of these curves varies over 20 dB as motor vehicles pass the measuring location, producing a wide range of noise values.

l It should also be noted that the varying ambient sound level at a location may rise above and f all below the siren signal level. If at some moment j the ambient sound level is too loud for a siren signal to be detected, a moment later it may decrease so that the siren can be heard. Since it is 1

impossible to know what the ambient sound level may be at any particular time during siren activation, it is necessary to look at statistical probability distributions of ambient soutid levels. One way to do this is to describe the sourJ in terms of levels exceeded for a certain percentage of the time. An L scund level for instance, is the sound level exceeded n percent of the time. Thus L is the sound level exceeded only 10 percent 10 of the time (almost the highest level), L 50 is the sound level exceeded 50 percent of the time (the median level), and L 90 is the sound level exceeded 90 percent of the time (almost the lowest level). L 10 and L 90 are important because most of the varying noise level remains between these values. In addition, L * '" " * "' " '

90 Level.

Acoustic TECHNOLOGY INC.

Another way .to characterize a varying noise level is to describe it in terms of equivalent sound energy (L ). L is the constant sound level which over the same time interval would expend the same amount of sound energy as the time-varying source. This equivalent constant level, L,q, places more emphasis on Loud, transient noise which can be disturbing, and is therefore useful in analyzing the ambient sound along major transportation routes. Also, L is often applied to highway noise 10 analysis since it is a measure of the louder traffic noise which can obscure a siren signal.

A graphic level representation of ambient sound level variation at a location, measured for approximately three minutes with A weighting is shown in Figure 10. During the measurement, a B&K Noise Level Analyzer was used to sample the varying noise level 10-times per second, each sample consisting of the noise level (in dBA) at that instant. This is done because it is necessary to break up the ambient sound level measurement, a continuous function, into many discreet values to apply statistical methods of analysis. On the basis of 1,800 total samples of the continuously varying noise Level, the levels of the statistical descriptors L ,L 10' L and L 90 were computed. They are shown in Figure 10.

50 i To depict the range of ambient sound level variation which exists at each measuring location, ATI prepared probability h'i s tog rams. A typical probability histogram is shown in Figure 11.

This histogram corresponds to l

l the noise variation illustrated in Figure 10, and shows the percentage of I

the samples that fall within certain 2 dB intervals. Thus, 10 percent l

hsrc TECHMY IP4C.

1 (about 180) of the 1,800 total samples fall in the range 42 dBA to 44 dBA, 15 percent (almost 270) fall in the range 44 dBA to 46 dBA, etc. A histogram with narrow spike would suggest a very steady ambient sound level, while one which is very spread out would represent a widely-varying ambient sound level.

6.3 DEFINITION OF AMBIENT BACKGROUND NOISE LEVEL The alert ability qf an outdoor warning siren signal is related to the minimum ambient sound level that occurs at a listener site, during .the time period that the warning signal of a siren is sounded. According to the FEMA-43 Standard Guide, if an early warning system includes a siren system, "the ambient background noise level should be measured in that one-third octave band (s) containing the predominant tone (s) of the siren (s) used".

Furthermore, FEMA-43 states that a siren alert signal should be 10 dB higher than the average outdoor daytime ambient sound level for the one-third octave band containing the predominant tone of the siren signal.

This is because the human ear detects pure tones if they are at least 9 dB higher than the background noise level.

The instantaneous, direct sound level meter measurements obtained by ATI during the ambient survey provide the dBA and one-third octave band frequency levels from 500 and 630 Hz, as presented in Table 1. Based on the actual field siren testing; predominant tones of,the sirens were found in the 630 Hz one-third octave frequency band. Although direct sound level l

1 l

meter measu,rements are good indications of the ambient level, the statistical descriptors L10' '50' '90 8"d 'eq P' *id' * * ***** ****"

of the fluctuating noise level. Table 2 pr'esents the summary of the statistical analyses conducted for all measuring locations. A comparison of the direct, instantaneous ambient sound level measurements with the statistically calculated ambient levels in Table 2 shows that approximately 75 percent of the direct measurements fall within the range of the L 10 and L values. Approximately 25 percent are similar to the calculated L 50 90 levels.

When one considers the relatively short duration of the peak siren sound signal for a rotational siren which is used in'the 10-mile EPZ of Catawba ,

Nuclear Station, the L value f the 630 Hz one-third octave band provides 10 an adequate measure of the average outdoor daytime ambient sound level for the purpose of a conservative design. It should be noted that the areas located outside 60 dBC siren acoustic coverage are surrounded by several sirens. Therefore, the public in these areas should be alerted by a siren alert signal emitted from more than one siren. The multiple number of siren alert signals wiLL have an effect of increasing the total duration of the peak siren acoustic signal. Therefore, the measured ambient sound levet for an area outside of the 60 dBC coverage can be defined as the L 10 or L value f the one-third octave band of the predominant siren tones 50 depending upon the number of sirens surrounding each area.

The areas located outside 60 dBC siren coverage were grouped into 23 regions as shown on Map 2. One to 7 Locations were selected for noise GAcousuc TECHNOt.OG  !

The L 10' 50' 8"d '90 values of the one-third octave band of the predominant siren tone for each measuring location are presented in Table

l 7.0 EVALtJATION OF THE EXISTING SIREN PROMPT NOTIFICATION SYSTEM The siren warning system for the 10-mile EPZ of the Catawba Nuclear Station consists of 67 FSC sirens installed to provide adequate acoustic alert coverage to the public within the EPI. According to the criteria of FEMA-43, the 60 and 70 dBC acoustic contours of the installed sirens were calculated and shown on Map 1. During the field testing, the siren system provided an actual siren fundamental f requency of 630 Hz, and a range of siren output at 100 feet from 123 dBC to 127 dBC. However, the computer analyses for Map 1 were based on the fundamental f requency around 570 Hz, and a siren output of 125 dBC, since 570 Hz is known to be more effective for far-field sound propagation than a fundamental of 630 Hz. It should be noted that the siren output of 113 dBC was used for siren 19. The data obtained from the siren far-field measurements indicate that the computer model used for the present study produced a more conservative acoustic coverage (2 to 3 dB Level of conservativeness).

An ambient background noise survey was also performed to document and determine the average measured daytime ambient sound levels in areas outside 60 dBC siren contours. The 10-dB-above-the-ambient criteria indicated in FEMA-43 was applied for these regions. Map 2 shows the average daytime ambient sound levels for the regions outside of the 60 dBC coverage. Accordingly, the 50 dBC acoustic contours for each siren were plotted to show total system coverage. However, since the EPZ has been extended beyond the geometric 10-mile radius, some areas along the extended EPZ are not covered by the existing siren acoustic coverage.

Examination gf Map 2 shows that portions of Regions 3, 4, 9, 10, 13, 16, and 17 have marginal 50 dB coverage primarily due to being near the EPZ boundary. Examination of Map 1 shows portions of areas having a population greater than 2,000 persons per square mile within Rock Hill, Clover, and Fort MILL which have marginal 70 de coverage (10 dB above assumed ambient of 60 dB).

8.0 CONCgUSIONSANDRECOMMENDATIONS The siren alert system coverage for Catawba Nuclear Station has been analyzed and verified through siren field testing. Sixty and 70 det siren contours have been calculated through*a computer model which used data from actual field measurements of siren performance. Extensive comparison of measured and predicted sound levels indicates that the acoustic model is accurate and conservative in its predictions. This trend has been observed at other nuclear power plant sites where ATI has performed extensive field testing to verify acoustic alert coverage. The installed siren sy, stem was found to provide the required 60 and 70 dBC public alert coverage for most areas. There are areas located outside 60 dBC contours. These areas are reduced by applying the 10 dB above-the-ambient criteria based on an ambient background noise survey. Results of this analysis indicates that the installed siren warning system provides an adequate notification to the

, majority of the public within the 10-mile EPZ. However, there are areas that require additional evaluation. Therefore, to determine full compliance with FEMA-43, it is recommended that further evaluation of the portions of Regions 3, 4, 9, 10, 13, 16, 17 outside of 50 dB coverage, and identified portions of Rock Hill, Clover, and Fort Mill, be performed to conclude if additional alerting coverage is required to notify the public in these areas.
