SUMMARY

f This report presents a computer analysis of the acoustic coverage of the prompt notification system for the plume exposure Emergency Planning Zone (EPZ) of the Davis-Besse Nuclear Power Station. The results of this analysis will be used in verification of the warning system to meet the guidelines set forth in FEMA's CPG-17 Outdoor Warning System Guide and the NUREG-0654 criteria. The objective of Acoustic Technology Inc. ( ATI) is to design a system that is technically adequate, cost effective, and reliable. This design meets regulatory requirements and will achieve the acceptance of the public as well as Federal, State and Local government

officials. The system design is a result of an extensive computer optimization process, and the design goal is to achieve a full acoustic alerting signal for the entire EPZ.

The warning system includes high power rotating sirens located throughout the 10 mile EPZ. Through the use of a computer model developed by Acoustic Technology, Inc.

( ATI), sound pressure levels have been calculated for up to 384 locations surrounding each siren. As will be explained in Section ill all factors which effect the sound pressure level have been considered in the model (i.e. hemispherical wave divergence, ground conditions, meteorological conditions) . The sound pressure level data was used to predict the extent of the 60 dBC acoustic coverage of the siren system for average yearly meteorological conditions. Given the generally low population density of the 10 mile EPZ, characteristic of the area, the ambient average sound level for the entire EPZ is assumed to be 50 dBC. Therefore, a prediction of siren sound coverage of a minimum 60 dBC has been made for each of the siren locations.

The computer analysis of the sound pressure levels in both graphical and tabular-forms for each sir.en is found in Appendix 1. The acoustic coverage of the sirens is noted on Map 1.

.l. INTRODUCTION

. RAFT The nuclear accident at Three Mile Island (TMI) underscored the need for better emergency preparedness procedures for commercial nuclear power plant licensees and for state and local officials involved with a general nuclear emergency. In January 1980, the Nuclear Regulatory Commission (NRC) and the Federal . Emergency Management Administration (FEMA) issued a document for interim use and comment entitled Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants (NUREG-0654, FEMA- R EP- 1 ) .

Among other things, this document lists the criteria for prompt notification of the public in the event of a general nuclear emergency. These criteria are presented in FEMA's Appendix 3: "

Means for Providing a Prompt Notification to the Populations".

The final legislation regarding prompt 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 _-

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."

Acoustic Technology, Inc. was contracted by Toledo Edison Co. to provide services in conjunction with the verification of the Siren Alert Notification System for Davis-Besse Nuclear Power Station. Using computer analysis, ATI has determined the overall 60 dBC acoustic coverage of the alert sirens located within the Davis-Besse Nuclear Power Station EPZ.

11. ACOUSTIC CRITERIA OF THE SIREN SYSTEM %

f jj In order to achieve a full alerting effect for the required areas within EPZ in compliance with NRC/ FEMA requirements, the siren system has been analyzed to provide a minimum of 60 dBC acoustic siren signal. The 60 dBC acoustic coverage has been determined by taking into consideration hemispherical wave divergence, atmospheric absorption, vegetation, ground effects, and upwind shadows.

NUREG-0654 ( Appendix 3) indicates that an acoustic signal of 10 dB above the aver-age daytime ambient level is an acceptable criterion for the de.: sign of a siren system.

In addition, this 10 dB differential above average daytime ambient level is meant to provide a distinguisable signal inside a home of average residential construction under average daytime conditions.

NUREG-0654 (Appendix 3) also indicates that the determination of adequate siren sound levels can be achieved by either of two options. Field surveys can be conducted to determine typical daytime ambient sound levels, and the siren system can be designed to achieve 10 dB above this documented ambient. As an alternative to field surveys, in areas with population density below 2,000 persons / square mile a sound level of 50 dBA can be assumed and the siren system can be designed to produce a minimum of 60 dBC.

Since the population in the EPZ of Davis-Besse Station is below 2,000 persons / square mile, the assumed ambient sound level of 50 dBA is us ed 60 generate the minimum 60 dBC sound coverage criteria for the Davis-Besse Siren System Design.

Ill. SIREN ACOUSTIC COMPUTER MODEL

.D **

W..;]J 7 The siren sound levels within the Davis-Besse Nuclear Power Station plume exposure EPZ were calculated by the use of a computer model developed by Acoustic Technology, Inc (ATI). This model takes into consideration meterological factors and land surface conditions which effect the propagation of sound generated by each siren. Land ele-vation gradients in the region surrounding the Davis-Besse Station are very slight and only a very small fraction of points are elevations exceeding 25 feet above the mean level so there are no hills which may act as barriers to sound. Hence, effects of land surface condition (i.e., vegetation, water bodies, etc.) on the propagation of sound waves overshadow the effects of hills in this region.

The greater determining factors of the sound pressure level contours were the changes

! in sound pressure as the sound wave passes over vegetation, marshland, water, open fields, and urban areas. The computer program which calculates siren coverage con-siders each of these surface conditions.

The computer program calculates the sound pressure at any given point around the siren to be evaluated. Each point is described by its distance from the siren and the surface condition which the sound wave must pass over to reach that point. Other variables such as wind speed, air temperature, and relative humidity take part in

! these calculations. In calculating the attenuation of the sound wave, the computer program uses codes to describe land surface condition directly to calculate this

, attenuation. The computer model calculates the sound attenuation with distance due to hemispherical wave divergence, atmospheric absorption, absorption due to vegetation and other types of ground cover, propagation of sound over water, propagation of l sound through urban and surburban areas, upwind sound shadows, and topographical barriers. These factors can be summarized as follows:

(h) Acoustic TECHNOLOGY

A. Hemispherical Wave Divergence: [% g i

%"dichj 44 4

The sound pressure level reduction due to hemispherical divergence is uniform in all directions at a rate of 6 dB per doubling of distance.

~

B. Atmospheric Absorption Molecular (atmospheric) absorption further reduces the sound energy. Absorption is dependent on the temperature and relative humidity of the air and is quite pro-nounced at large distances and at high frequencies. To determine the effects of meteorological conditions on the acoustic coverage of the design warning system, sound pressure levels were analyzed using yearly average meteorological conditions.

The yearly average is used to avoid under or over design of the siren system. These parameters were obtained from the Toledo National Weather Service and the Evacuation Time Estimates Report for Davis-Besse Nuclear Power Station. The yearly average relative humidity was determined to be 73% and the average temperature 50 F.

C. Ground Effects:

Ground attenuation is a function of the contour and covering of the ground and of the height of the siren and receiver above the ground. The ground covering con-ditions at various directions and distances from siren to receivers were read directly from USGS maps. Sound travels from a siren to a receiver location by two paths:

the direct line-of-sight path which is the primary path of outdoor sound propagation, and the ground reflected path. Both of these propagation paths are subject to sound attenuation due tq the effect of the ground cover existing between the siren and the dh

l receiver location.

L)" h*T The amount of attenuation resulting from the sound propagation path can attenuate the sound from the siren substantially at the receiver location.

Five types of ground cover are distinguished from the 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 (see below), so attenuation by this ground cover is not as great as by denser vegetation.

3. Water, marshes - water acts as a reflector for sound propagation.

Therefore, attenuation is very slight.

4. Open fields - where there is no dense vegetation or barriers to sound, attenuation is only slight.

5. Urban and Suburban areas - sound reflects well off of pavement i

at acute incidence angles. Sound is attenuated to a significant extent in urban areas, close to the siren, where buildings act as sound barriers and where reflection is poor due to a high incidence angle, while in urban areas further away from the siren, sound propagates at a lower attenuation rate, as a result of in-creased reflection due to the lowered angle of incidence (see Figure 1).

l D. Wind Shadows [h Wind gradients near the ground are nearly always pos'itive; that is, the windspeed increases with height. As a result, a shadow zone is most commonly encountered upwind from a siren because there the wind gradient bends the sound rays upward.

4 Downwind, the sound rays are bent downward, and no shadow zone is produced.

Cross wind there is a zone of transition. For any given wind direction, a unique sound pressure level contour is produced by the siren, given a certain wind speed.

The speed and direction of an average wind fluctuates, depending on the time of day and the time of year. The yearly average wind condition at Davis-Besse Station is 10.3 mph and this value was used as input for the computer model. The wind speed and direction has a minimal effect on the propagation of sound from the siren and it is discussed later in Section V.

E. Topography 1 Hills, if large enough, can act as partial barriers to sound and can cause a sign-i a ificant reduction in sound pressure level within their shadow zones. However, land elevation gradients in all regions surrounding the Davis-Basse Station are very small.

1 No sirens are located in areas in which the changes in land elevation are large enough Y

i to potentially create shadow zones. Thus the effect of hills was not included in our calculations of the sound pressure levels generated by the siren system.

Another factor used as input in the ATI computer model is siren sound level rating Manufacturers of high power sirens claims their sirens will produce a certain sound 4

pressure level at ,100 feet away from the siren. ATI has tested the acoustic per-formance of all of these sirens in an anechoic chamber (free field) and the appropriate rating for the sirens purchased by Toledo Edison was used as input in the computer. model:

facturer.

IV. VERIFICATION OF SIREN ACOUSTIC MODEL 4

i In order to verify the accuracy of the Acoustic Technology Inc. ( ATI) model the measured sound levels were compared to those predicted as shown in Table 1.

Excellent agreement was obtained from all data points under consideration. It 's noteworthy that the model predicted values are slightly less (1-3 dB) than those measured values. This indicates a further conservatism in determining the sound level contours.

4 V. THE EFFECT OF WIND ON SIREN SOUND COVERAGE i

in the internal areas of the 10 mile EPZ the effect of wind will be minimal. For an array of sirens such as the case within the inner parts of the EPZ, the wind shadow due to upwind effects will be nearly compensated by the down wind effect of the adjacent siren in the direction of the wind. Therefore, the effect of wind will dominate only at the boundary areas of the siren system. The yearly average wind condition for Davis-Besse Station is 10. 3 mr-5. This value has been used as input in ATI's Computer Model. The results for average wind speed of 10.3 mph indicate 4

that the effect of the wind shadow is taking place at distances of approximately 5,000 feet from the siren. The wind shadow results indicate that the 60 dBC contour is shifted downwind by an average distance of 1,000 feet toward the siren.
