, s.- /
1.0 Introduction . 2. This report has been prepared by the Louisiana Power & Light Company to describe and identify the integrated components of the Waterford-3 alert / notification system. The development and implementation of this system has been jointly undertaken by Louisiana Power & Light, St. Charles q Parish, St. John the Baptist Parish and the State of Louisiana. This report is intended for use by the staffs of the Nuclear Regulatory Commission and i the Federal Emergency Management Agency in determining the license's compliance with alert / notification system regulation as established in
- 3 Title 10 of the Code of Federal Regulations Part 50.47 and Part 50, d
Appendix E; and guidance in NUREG-0654, FEMA-REP-1; and FEMA-43, Standard - i () Guide for the Evaluation of Alert and Notification Systems for Nuclear Power Plants. 4 1.1 Facility Description i j Waterford-3 SES is a pressurized water reactor with a net rated output of j 1153 MWe. Waterford-3 is owned an<1 operated by Louisiana Power & Light and is I expected to go into commercial operation .in the fourth quarter of 1984. Waterford-3 is located at Taft, Louisiana in St. Charles Parish on the west bank of the Mississippi River approximately 35 miles west of New Orleans, ( Louisiana. i 0 1 Rev.1 e
s q The-10 mile Emergency Planning Zone for Waterford-3 encompasses parts of St. Charles Parish and St. John the Baptist Parish. This EPZ is divided by the Mississippi River with land extending approximately 2 to 3 miles on either' side of-the River. The EPZ contains extensive wetlands and also extends into Lake Pontchartrain to the northeast. Lac Des Allemands is almost entirely contained in the southwest portion of the EPZ. 1.2 Governmental Authority for Activation of the Waterford-3 Alert / Notification System St. Charles and St. John the Baptist Parishes function under home rule charter provisions of the Louisiana State Constitution. Both have Parish Presidents who act as chief executive officers for the Parish and Parish
)
i Councils which act as a Legislative body for the Parish. There are no ._ municipalities or other subdivisions of general governmental authority in either Parish. The Louisiana Nuclear. Energy Division (LNED) of the Loui'siana Department of Environmental Quality is the lead State agency for the development of
- radiological emergency response plans for fixed nuclear facilities. LNED 4
i also serves as the lead State technical agency for response to a fixed nuclear facility accident. The Louisiana Office of Emergency Preparedness (L0EP) 1 of the Louisiana Department of Public Safety is the lead State resource support agency for response to an accident. LOEP also maintains the State warning l point and is responsible for activation of the State Emergency Broadcast System (EBS). Details of State response to an accident at Waterford-3 are contained in the Louisiana Peacetime Radiological Response Plan. 2 Rev. 1 m
m Attachment 1 of this Plan contains the response plans for St. Charles Parish
~'
and St. John the Baptist Parish. These plans and their accompanying implementing procedures detail authority and methods for activation of the alert / notification system. 1.3 Activation of the Alert / Notification System In the event of an accident at Waterford-3, notification would be given from the Waterford-3 Control Room to St. Caarles Parish, St. John -the Baptist Parish, LNED and LOEP simultaneously. If a protective action is required, Waterford-3 emergency personnel would make a recommendation to off-site authorities based on plant parameters and supported when available by field monitoring data. This recommendation is evaluated by the State using an t 1 independent dose assessment method and separate field monitoring data. The O 3 l V Waterford-3 recommendation is then either confirmed or strengthened by the State and passed onto the Parishes for implementation. The Parishes then implement the protective action based on their state of readiness. The first step in this process is the activation of the alert system for the involved sections of the 10 mile EPZ. The Waterford-3 10 mile EPZ has been divided into 16 sections to allow for decision making flexibility at the i time of an accident. All aspects of activation of the primary alert system are the direct responsibility of the Parishes. At the time the alert system is activated, notification messages are released through various emergency broadcast media. Components of the alert / notification system are described in the sections which follow. O t 3 Rev.1
2.0 The Alert System
' s\
(V . The primary Waterford-3 alert system is comprised of fixed sirens, a mobile siren, helicopters fitted with mounted alerting devices, the St. Charles Parish Industrial Hot-Line, the St. John the Baptist Parish Industrial Mutual Aid Radio System, automatic telephone dialing devices, school board radios and the Coast Guard for notification of ships on the Mississippi River. As a back-up to this system, the Parishes have available Sheriff's Deputies and fire company responders to conduct route alerting, Louisiana Department of Wildlife.and Fisheries personnel for wetland alerting, Louisiana Department of Commerce and Industry calls for industrial alert and notification as well as tone-alert radios. Each of the components of the , t, primary and back-up alert systems is more fully described in this section. 2.1 The Primary Alert System 1 2.1.1 Fixed Sirens There are 52 fixed sirens as part of the primary alert system. There are 51 model WS-3000 and WS-3000R sirens and 1 model WS-2000 siren manufactured by the Whelen Engineering Company. Forty-seven of the sirens are located within the'10 mile EPZ and 5 are located outside the EPZ but serve to alert persons at the perimeter of the EPZ. A map with the final locations and coverage areas of these sirens is included as a part of Attachment 5.11 of this report. 4 Rev. 1 4 f
t
,q The WS-3000 and WS-3000R sirens are radio activated from the appropriate U' Parish EOC's. Both St. Charles and St. John the Baptist Parishes maintain separate command frequencies for sirens located within their jurisdictions.
The WS-3000 and WS-3000R are solid-state, electronic outdoor rotating siren-rated at 124 dBc at 100 feet. These sirens are powered by a 24 volt DC battery power source which is continually recharged by external AC power. In the event of a power failure, these sirens would be capable of sustaining normal operations for a 30 minute period. Both the WS-3000 and WS-3000R produce five standard alerting signals including wail, civil defense alert, attack, air horn.and hi-lo as well as having a public address function. As determined
~
by St. Charles and St. John the Baptist Parishes, the wail signal will be used to alert the public of an emergency at Waterford-3 requiring action. This
,information concerning the use of the wail signal has been communicated to the public in the Waterford-3 Public Information Booklet. ._
Responsibility for activation of the sirens located in the respective parishes rests with St. Charles Emergency Preparedness and St. John Civil Defet se. The sirens can be activated by radio command from the Parish E0C's or from the Parish mobile vans. Both the St. Charles and St. John sirens are activated on the Parish command and control frequency. Sirens can be activated individually, as part of groups according to protective response areas or the entire parish system can be activated simultaneously. Should a siren fail to activate, designated fire companies responsible for monitoring siren activation would report this failure to the Parish EOC. Civil Defense authorities would in turn request manual activation O 5 Rev. l
~
j
r~% of the siren by fire company personnel trained in the working of the siren U control features. Should manual activation fail, then route alerting procedures would be implemented. These procedures are described in section 2.2.1. The model WS-2000 siren used as part of the alert system is located in St. John the Baptist Parish at the perimeter of the 10 mile EPZ. This siren will be used essentially to alert personnel who at the request of the St. John Civil Defense Director will alert persons in camps on the western shore of Lac Des Allemands. The WS-2000 is a non-rotating siren capable of producing 106 dBc at 100 feet. This siren can produce the same alerting signals as the WS-3000 and is manually activated upon radio command from the St. John EOC. s 2.1.2 Mobile Siren -- O-~ St. John the Baptist Parish Civil Defense owns a model WS-2000 siren which is mounted on a trailer with a self-contained generator. This mobile siren will be used primarily to alert persons who may be in wetland areas where roads are available. Camps in wetland areas along with alert routes have been identified by St. John Civil Defense. These routes are identified in Attachment 5.4. The areas to be alerted are within the 5-10 mile radius
; of Waterford-3. Based on normal conditions, it is estimated that alerting along these routes will take 24 minutes. (Note: It is estimated that activation of this system will require 15 minutes from time of notification.)
It may also be used to supplement siren coverage in areas where fixed siren failure has occurred. A l \~-) l ! 6 Rev. 1
. f
pT Two Civil Defense volunteers have been tasked with the responsibility of taking the siren to the areas where it may be needed and activating it. In addition, Sheriff's Deputies using a portable trailer hitch could transport and activate the mobile siren if necessary. 2.1.3 Helicopters Equipped with Alerting Devices Agreements have been established with Air Logistics of Eslle Chasse, Louisiana for the use of four helicopters to assist with the alert / notification of persons who may be in wetland and lake areas within the Waterford-3 10 mile EPZ. These helicopters are stationed approximately 20 miles from the 10 mile EPZ. A copy of this agreement is included as Attachment 5.10. As
- stated in the agreement, these helicopters would be made directly available to St. Charles Parish and St. John the Baptist Parish within 15 to 30 minutes -
of the request for their activation. Upon arrival at predesignated locations within each Parish, the helicopters would be fitted with specifically designed alerting equipment. A designated Parish emergency responder would then accompany the helicopter to operate the alerting equipment and to assist the pilot with the location of routes of travel. The helicopter alerting equipment consists of an amplifier / loudspeaker model STS-400 rated at 250 watts manufactured by Applied Electro Mechanics, Inc. Extensive airborne field testing of the helicopter alerting system was conducted in the summer of 1984. An analysis of these tests is included as Attachment 5.12. As a result of this testing and analysis, the decision has been made to fly the helicopter at an altitude of 500 feet and a speed of 60 miles per hour. 7 Rev. 1
i
,_s
\ . Attachment 5.5 depicts helicopter routes that would provide coverage in
-# wetland and lake areas in the entire 10 mile EPZ. Based on these routes the time estimates for alerting in each quadrant of the EPZ are as follows: Quadrant A - 40 minutes for areas between 5 and 10 miles from the Waterford-3 site; Quadrant B - 38 minutes total and 15 minutes for that portion within 5 miles of the site; Quadrant C - 44 minutes total and 15 minutes for that portion within 5 miles of the site; and Quadrant D - 44 ,
minutes total and 15 minutes for that portion within 5 miles of the site. (Note: These times are for departure from the Parish E0Cs and does not include activation from the helicopter point of origin.) In an emergency, other routing may be developed that directs coverage only to those areas where protective actions are required. s The alert message transmitted from the helicopter are prerecorded to ._. [ assure accuracy and consistency of information and include both a verbal
?
I message and an alert tone. The helicopters will fly at altitudes and at speeds which have been calculated to determine the most effective way in which to communicate a verbal message. Test results indicate that the . verbal message would be clearly audible at a 1/2 mile range from the helicopter in both directions. 2.1.4 St. Charles Parish Industrial Hot-Line 1 St. Charles Parish maintains a private tie telephone Industrial Hot-Line i which connects the Parish EOC with 22 major parish industries including Waterford-3. (Industrial Hot-Line stations are available at Waterford-3 in the Control Room, Technical Support Center and the Emergency Operations 8 Rev. I t i 1
N Facility.) These industries include all firms possessing a significant toxic or hazardous materials potential within the Parish. The Parish EOC can receive or initiate calls from or to each of these industries, and the EOC can create co'nference calls between any number of industries as needed.
Calls cannot be initiated between industries independent of the EOC. (Note: Attachment 5.7 lists the Industrial Hot-Line Roster.) The Industrial Hot-Line will be used as the primary means of alert and
~
notification for major St. Charles Parish industries. This will allow for confirmation of the receipt of an emergency related message by the industry who in turn will notify plant workers should an action become necessary. Industries most likely to have high ambient noise levels will be assured of
- notification. The industry will in turn be able to dismiss workers should i
I this become necessary while insuring that proper shut-down procedures are --: maintained, l 2.1.5 St. John the Baptist Parish Industrial Mutual Aid Radio System St. John the Baptist Parish maintains an Industrial Mutual Aid Radio System with the Dupont Chemical Company, Marathon Oil Company and Kaiser Chemicals. This system allows the Parish EOC to directly alert and notify those major industries mentioned above. As with the Industrial Hot-Line described in section 2.1.4, this radio system allows for the confirmation of messages and the direct notification of industrial employees of possible protective actions through plant management. O e R w. 1 I
/~ 2.1.6 Automatic Dialing Devices (Tm-)
St. Charles Parish and St. John the Baptist Parish have in place the RECALL automatic dialing devices produced by I. H.' Systems, Inc. for the no'tification of smaller industries not on the Industrial Hot-Line or the Industrial Mutual Aid Radio System. These devices will also be used to alert and notify facilities such as nursing homes and day care centers. St., John the , Baptist Parish will alert parochial schools not on the School Board radio ' system with this device. St. Charles Parish will also utilize this device to alert parochial schools within the 10 mile EPZ. A listing of calls to be made by the automatic dialing devices for each Parish is contained in Attachments 5.8 and 5.9. l .- The dialing devices available to the Parishes utilize a software based computer system to make preprogrammed calls. The system allows calls to be made by protective response area, by group listing or for all potential recipients at the same time. A prerecorded. taped message will be read to each person answering the calls. A party who does not answer after a specified number of rings on the first call will be queued at the end of the call list and then called again. After two calls, it is assumed that no one is available at that location. This system also contains a printer which will provide a report on completed calls and those parties who could not be reached. The Recall system meets all applicable FCC emission and telephone communication device g standards. This system can be expanded to meet as large a number of d potential calls as is necessary for the Prrishes. 10 Rev. 1
,-, 2.1.7 Provisions for Hearing Impaired Individuals 'y)
Contacts have been made by representatives of St. Charles Parish and St. John the Baptist Parish with a number of organizations and agencies which < care for or work with hearing impaired persons in order to identify such persons living alone within the Waterford-3.10 mile EPZ. This list of contacts includes representatives of the Louisiana School for the Deaf, Associated Catholic Charities, Parish Health Units, Parish Lions Clubs as well as direct contact with relatives of hearing impaired persons. This survey has revealed that there are no hearing impaired persons in St. Charles Parish who do not live with persons who are able to hear, and that there are six hearing impaired persons living in three separate households in St. John the Baptist Parish. The special needs cards which are distributed with the Public Information Booklet have bee'n used to confirm these results ._ l s_, and to identify other hearing impaired persons needing assistance. f The St. John Civil Defense Director has identified either relatives or volunteers living in the vicinity of the hearing impaired persons who will accept the responsibility for notifying these persons in the event of an emergency at Waterford-3. The persons responsible for notification will be included on the automatic telephone dialer for direct notification from the Parish EOC. In addition the Parish Health & Medical Officer will confirm the notification of the persons responsible for notifying hearing impaired persons as part of his normal scope of activities in an emergency. This same method of notification for the hearing impaired will be adopted by St. Charles Parish should hearing impaired persons living alone be identified at some time in the future. 11 Rev. 1 t 4
9 2.1.8- Provisions for River Traffic Both Parishes rely on the U. S. Coast Guard to alert vessel traffic on the Mis ~sissippi River in the event of a Waterford-3 accident. The Coast - Guard can be accessed from each Parish EOC by radio. The Coast Guard would in turn notify river traffic if protective accions were required. The notification of ships on the river would take place by radio using the Coast Guard freq2ency or by the stoppage of shipping by the Coast Guard prior to its entering the 10 mile. EPZ if necessary. ' 2.1.9 Provisions for Special Facilities Special facilities requiring alert and notification include schools, ), hospitals, nursing homes and jails located within the 10 mile EPZ. Both .- O Parishes have a School Services Officer as part of their EOC staffs. They I also have both radio and telephone communication from the EOC to the School Board Administrative offices. In the event of an emergency requiring response by schools, notification would be made from the Parish E0C to'the School Board Administrator. In St. Charles Parish, notification would be made by the School Board Administrator to individual school principals by-telephone. Parochial schools are included on the St. Charles Parish automatic dialing system. In St. John Parish, the School Board maintains a radio system with all public schools. Calls would be made from the EOC to s private and parochial schools. St. John Parish also plans to include private and parochial schools on the automatic dialing system. 1 12 Rev. 1 U 1
Hospitals and nursing homes within the 10 mile EPZ will receive alert act (~~) V notification directly from the Parish EOCs through the designated Health and Medical Officer. This will be accomplished by making telephone calls. In addition,'the Parishes' have the capability of co'amunicating with the hospitals via the Louisiana Hospitals Association radio frequency. Both Parishes have jails located within the 10 mile EPZ. These jails are located in the same building as the EOCs. Alert and notification of these facilities would be made by the Law Enforcement Officer who i~s part of the l
'EOC staff.
2.2 Pack-Up Alert Systems In addition to the primary alert system, there are a number of back-up -- means that would serve to provide alert to the public should a primary system component fail. These back-up means include the route alerting in populated and wetland areas, calls to industries by the Louisiana Department of Commerce & Industry and tone-alert radios. These systems are more fully described in this section. 2.2.1 Route Alerting in Populated Ateas As described in section 2.1.1, the Parish EOCs will request that firemen monitor siren activation and attempt manual activation in the event of siren failure. If manual activation should fail, firemen or Sheriff's deputies would be requested to conduct route alerting in those areas where O 13 Rev. 1 i
f-~y siren coverage did not occur. In St. John the Baptist Parish route U alerting would only take place in the event of a fixed siren failure coupled with the unavailability of the mobile siren. Firemen or Sheriff's deputies would deliver the message to the public in~the area needing coverage to turn to appropriate radio or television stations for further information. 2.2.2 Route Alerting in Wetland Areas In wetland areas and in camps along the lakeiront, Louisiana Department of Wildlife and Fisheries personnel can conduct route alerting to augment
. alert coverage provided by helicopters and the mobile siren. Route 5 ] ~
alerting would be called upon only in the event of the failure of a primary --
] ; [\ wetland and lake alert component to be available or if the Parishes desired confirmation of the receipt of alert. Wildlife and Fisheries personnel are assigned in St. Charles and St. John the Baptist Parishes as their regular work assignments. During an emergency, these personnel report for assignment to the Parish Emergency Directors. Route alerting in wetland areas would be conducted either from boats equipped with sound amplification equipment or by going directly to wetland camps. These camps have been identified in advance in each Parish and are identified in Attachment 5.6.
2.2.3 Louisiana Department of Commerce and Industry Alert Activities As established in State Implementing Procedures, the Louisiana Department l ~~ of Commerce and Industry will make telephone calls to all industries and b large commercial interests in affected areas within the 10 mile EPZ should 14 Rev. 1
?
s 1 7s alerting be necessary. This procedure will be used~as a supplement to U primary notification received via the-Industrial Hot-Line, Industrial , Mutual Aid Radio System and the automatic telephone dialing devices. In addition to assuring that the alert message has been received, the-Department of Commerce and Industry will attempt to identify industries who may require special assistance at the time protective actions become necessa ry. 2.2.4 Tone-Alert Radios St. Charles and St. John the Baptist Parishes have available to them a limit'ed number of tone-alert radios which may be used to augment alert
; coverage in camps in wetland areas or to special facilities. St. Charles A
d
/~
Parish intends to distribute these radios to larger camps. St. John the ._ Q. , t ( Baptist Parish plans to utilize tone-alert radios at private and parochial schools which are not on the School Board radio system. 3.0 The Notification System . , St. Charles and St. John the Baptist Parishes together with the State of Louisiana have developed messages for release to the public at the time that protective actions are needed. Two sets of messages are available; 4 one is aimed at the population within the 10 mile EPZ and the other is i i aimed at areawide population groups who may be indirectly affected by an accident. The messages for the 10 mile EPZ population are consistent with the Waterford-3 emergency classification scheme and specifically cover i initial notification, breathing protection, shelter-in-place, evacuation, () 15 Rev. 1
.,- _ _ _ . _ _ . _ _ . _ . _ _ - . _ . _ ,__ J.

>y s
,e x school evacuation and reentry. These are accompanied by a series of inserts which detail information such as area descriptions, evacuation routes, pick-up points and scho31 evacuation information for each of the
' sectors which may be affected. As described'in this section, the Parishes will release messages intended for the 10 mile EPZ population directly through local media at the same time that the State releases these messages through statewide EBS. Areawide messages will be released by the State through statewide EBS. These areawide messages include information on actions being taken inside the 10 mile EPZ such as sheltering and evacuation, as well as messages directed at the agricultural conmounity and recovery.
Details of the methods for release of this information are included in this section. Both Parishes maintain the capability of monitoring both radio and , i television messages from their EOCs. '
.i 9 s i 3.1 The Primary Notification System 1
i . 3.1.1 Parish Release of Notification Messages 1 A radio system on a dedicated frequency is installed for the St. Charles ( and St. John the Baptist EOCs which links them directly with radio station i WCKW/WKQT. This radio linkage permits the on-air broadcast of emergency messages directly from the Parish EOCs. The sole purpose of this radio is j for the release of notification messages from the Parish EOCs to WCKW/WKQT. l l WCKW and WKQT have conunon ownership and their broadcasting facilities are in 1 the same location. WKQT is an AM station which operates on a limited j broadcast schedule. This station's management has agreed and has the authority to return to the air to deliver notification messages in an 16 Rev. 1 i
- )
emergency. Broadcast personnel are available at the station 24 hours per (s day as part of WCPW-FM 24 hour, seven day per week operations. WCKW and WKQT are located at the perimeter of the 10 mile EPZ. WCKW broadcasts on the FM band at 100,000 watts of rated output power. Its minicum coverage area is estimated to be 50 miles in radius from the tower
. location. WKQT is an AM station with 500 watts of rated output power. Its coverage area is estimated to be 40 miles in radius. The coverage area for i
both of these stations includes the entire 10 mile EPZ for Waterford-3. 3.1.2 State Release of Notification Messages
. L0EP is the State Agency responsible for the activation of the statewide EBS. In the event of an emergency at Waterford-3 requiring protective .- '. s actions, L0EP would be notified directly by St. Charles and St. John the 1
1 Baptist Parishes of the action to be taken and the message to be released. The message for release to the population within the 10 mile EPZ would be prepared in hard copy by the LOEP Public Information Officer, confirmed with the respective Parish Public Information Officers and then transmitted via facsimile machine to radio station WWL in New Orleans. WWL is the ! Common Program Control Station (CPCS)-1 for both radio and television for the Nta Orleans metrop'olitar. area. This station broadcasts at 50,000 watts l of rated output power and has a minimum daytime coverage area of 200 miles l which includes the entire 10 mile EPZ. When an emergency messahe is released by WWL, then it becomes available to all CPCS-2 stations in the same area. This assures the release of EBS information to all major radio and television stations in the area serving the Waterford-3 10 mile EPZ. 17 Rev. 1
f-'S LOEP is also responsible for the release of areawide emergency messages. V These messages are originated by LOEP on the authority of the Assistant Secretary of the Office of Emergency Preparedness - Department of Public Safety. These messages wculd be delivered directly'from LOEP Communications' to all areawide EBS stations. 3.2 The Secondary Notification System 3.2.1 Cable TV Override St. Charles and St. John the Baptist Parishes have available to them the
- means of placing an emergency message to Parish residents who have cable TV service. These systems enable each Parish to place a voice message over
- all cable TV stations simultaneously. Both systems provide for a written ,
message to be provided on the appropriate cable TV access channels for each Parish. St. Charles Parish officials estimate that 75% of all Parish residents subscribe to cable TV. In St. John the Baptist Parish cable TV subscribership is estimated at 40%. 4.0 Siren System Testing and Maintenance 4.1 Siren System Testing Siren system testing will be a shared responsibility between LP&L, St. Charles Parish and St. John the Baptist Parish. The Parishes will conduct audible tests at the beginning of each month. Silent tests will be
-s conducted in the middle of the month by LP&L personnel. Documentation of '~'
the performance of these tests will be jointly maintained by LP&L and the 18 Rev. 1 I
r ] _ gx Parishes. The silent test procedure available with the WS-3000 and WS-3000R model sirens as recommended by the manufacturer provides information on the availability of the following: (1) AC Power (2) DC charging and operating current (3) Partial amplifier and speaker driver operation (4) Full amplifier and speaker driver operation (5) Rotor operation As the testing nomenclature implies, no audible sound is released during silent testing. i Each siren in the system will be sound tested on the first Thursday of each ._ l j /~}
\m- month at noon. The Parishes' intention to' conduct such tests has been a
4 . communicated to the public in the Waterford-3 Public Information Booklet. These tests are expected to last for one minute or less and may involve one or more of siren tones available on the WS-3000 and WS-3000R. It is expected that the Parishes will accompany the tests with a public address message
- informing persons that a test is being conducted. The Parishes will designate j
i volunteers in the area of each siren to listen for activation and to report any activation failures. Siren activation is also verified by LP&L siren maintenance personnel. In addition to the monthly sound tests and any siren activation which is conducted in association with the Waterford-3 annual exercise, both I Parishes will conduct an annual full scale test of siren activation. This b test will be conducted at a time mutually agreeable to both Parishes and I l l 19 Rev. I t I
-s will involve the testing of all- siren functions as well as individual,
- group and full activation. This testing willlbe announced to the public prior to the time tests are conducted. The full scale test will also aid in
-determining the adequacy of-siren coverage. Decisions on the additions of new sirens are expected to be made in connection with the analysis of l
population data following this test. Siren test documentation will be maintained by LP&L and will be prcvided to the Parishes for annual submittal to FEMA as part of certification procedures. Any siren activation failures discovered by the Parishes will be reported immediately to LP&L for corrective action. 4.2 Siren System Maintenance i i } .
\.) Siren system maintenance will be the responsibility of LP&L. As was I
mentioned in section 4.1, LP&L will be responsible for the monthly i silent testing 'and correction of any identified deficiencies. On a quarterly basis, each siren will be visually inspected both internally and externally. Batteries, receivers and tone generators will be individually tested and calibrated or charged as necessary. In addition, each siren will undergo annual preventive maintenance procedure. This will include extensive battery testing and replacement if necessary and lubrication of , the rotor drive assembly. Twenty-fisa percent of the siren system will I , have the preventive maintenance procedure performed each quarter. j i LP&L will maintain documentation of all maintenance activities.

Siren System Testing Summary The Waterford-3 siren system was installed by LP&L Division construction personnel during the period November 1982 - January 1983. An initial operability test for the system was conducted on March 26, 1983. The purposes of this test were to: (1) Determine whether siren activation could be achieved from the Parish EOCs; (2) determine if individual, group and full. system activation could be achieved as designed; (3) determine if proper rotational functions could be achieved for each siren; and (4) determine if an audible signal ,could be heard at the perimeter of each projected siren coverage area. St. Charles and St. John Parishes drew upon i j volunteers to monitor siren performance during this test. ._. .! D.
; \~-f St. Charles Parish experienced mechanical rotation problems with a large
. number of sirens during the March 26th test. This made it impossible to achieve verifiable findings regarding siren coverage areas. It was agreed that the mechanical rotation problems would be corrected and that the sirens I
would be retested at a later date. St. John Parish was able to successfully test its siren system on this date. As a result of this test, it was determined that the following action should be taken: 5.2-1 t
f_s (1) Two sirens would be added to the St. John Parish system.
-t )
v . (2) Two sirens would be moved to new locations to augment coverage. (3) ..A mobile siren would be purchased to assist with alerting in wetland areas. At the conclusion of the March 26th test, it was agreed by LP&L and the Parishes to request that the Whelen Engineering Company supply techni' cal personnel to check the mechanical functions of all sirens, to test the sound output of all sirens in the system and to install diagnostic modifications. These modifications included having AC and DC LEDs remain on at all times, single touch activation of manual control features and l g provisions for siren rotation on silent test. Whelen Engineering performed ..; these modifications and tests in April and May of 1983.
?
On June 16, 1983, St. Charles Parish retested its siren system using the same test criteria as established for the March 26th test. This test resulted in the following: (1) Two model WS-3000 series sirens would be added to the St. Charles Parish system. (2) Two model WS-3000 series sirens would be moved to new l locations to augment coverage. O 5.2-2 Rev. I t f s
x On November 4 - 11, 19d3. representatives of Acoustic' Technology, Inc. (ATI) conducted field testing for the Waterford 3 siren system. This testing was aimed at determining siren coverage areas based on actual sound level measurements and at developing an ambient noise level data base within the Waterford-3 10 mile EPZ. The results of these tests are fully documented in Attachment 5.10 of this report. As a result of these tests, the following modifications were made to correct deficiencies and to allow for some future population expansion to the siren system: (1). Three additional model WS-3000 series sirens were added to the St. Charles Parish system. g (2) Six additional model WS-3000 series sirens were added to the St. John Parish system'. .- [O
~
l' (3) One additional model WS-2000 series siren was added to the St. John Parish system. In the summer of 1984, additional tests were conducted by ATI to verify siren coverage within the 10 mile EPZ. Results of the siren verification tests can be found as Attachments 5.11 and 5.12 of this report. In addition, tests of the helicopter warning system were also conducted in the summer of i l 1984.

SUMMARY
im N Louisiana Power & Light Company (LP&L) 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 Waterford-3 Steam Electric 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 Sttndard Guide for the Evaluation of Alert and Notification Systems for Nuclear Power Plants (FEMA-43): September 1983. The original warning system design included 42 high power, rated 124 dBC at 100 feet, ro t a t i on.a l, electronic sirens.- Verification of the acoustic Os coverage for the siren warning system was accomplished by using a computer model developcd by ATI, and field measurements of sound levels. The actual measured siren output at 100 f eet, obtained through field testing for a sample number of sirens, was used to predict the extent of the 60 and 70 dBC 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 from the ATI acoustic
. computer model. It was found that the predicted and measured siren SPL's were in excellent agreement, and that the ATI computer model calculated i slightly conservative predictions of siren acoustic coverage.
j 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 l ! deAcousTic TECHNOLOGY INC. u, I
J ambient so'und Levels, or provides 60/70 dBC acoustic alert coverage 0 depending upon the population density of the area. A background ambient noise survey was conducted to document the average measured outdoor ambient sound level in various locations within the 10-mile EPZ. Based on . the ambient survey characteristic ambient sound environment zones within-the EPZ were developed, and are presented in Map 1. Map 2 shows the composite acoustic coverage of the 60 and 70 deC siren alert signal of the entire system with 42 high power sirens,.which is based on the original siren data obtained f rom the actual siren testing. The 60 and 70 dBC coverage for the installed sirens was evaluated based on the demographic distribution and ambient sound environments within the EPZ, to determine if 100 percent of the population receives adequate alert coverage. Based on this analysis, nine additional siren locations were recommended to provide full acoustic alert coverage to all populated areas within the EPZ. Map 3 indicates the final acoustic coverage with the total 51 sirens. l O

1.0 INTRODUCTION
p '
-O Prompt notification siren systems designed and installed by nuclear power plant Licensees are recommended to be tested to determine their compliance with Nuclear Regulatory Commission (NRC) and FEMA requirements in NUREG-0654 and FEMA-43. In the event of an emergency, the responsibility of using the system wiLL be transferred to the appropriate local and/or state authorities. The major objectives of the testing is to document actual installed siren performance, and to verify that the system is adequate and capable of alerting the public within the EPZ of the nuclear power plant as outlined in FEMA-43.
The Waterford-3 primary prompt notification system uses WS-3000 electronic rotational sirens. The installed sirens are manuf actured by Wheten Engineering Co. (WEC) and have a manuf acturer's rating of 124 dBC at 100 feet. These electronic sirens have a back-up battery power supply which is continously recharged via external power lines. In the event of any external power f ailure, the battery power supply can sustain normal siren operation for 30 continuous minutes. In November 1983, a team of consultants and engineers f rom ATI conducted siren system field testing. The field test program for the siren system included:
- 1. Evaluation of Siren Sound Pressure Lesel output at 100 feet.

- b. Verification,of acoustic coverage, and
- c. Identification of acoustic shadow zones (areas of inadequate siren sound coverage).
- 3. Determination of the maximum siren sound levels accessible to the public.
Siren sound level measurements were made for a representative sample of 13 least a 95 percent sirens. This sample size was determined to provide at confidence interval with the assumption of a 1 de Level of accuracy for average siren output. ATI's test engineers, assisted by personnet f rom LP&L and local civil defense personnel, performed the sound Level measurements using modern acoustic instrumentation which conforms to standards set by the American National Standards Institute (ANSI). As part of the verification of the siren alerting system's performance for Waterf ord-3 Steam Electric Station, an ambient background noise survey was conducted to determine the average measured outdoor daytime ambient sound Level throughout the entire EPZ. Predictions of the 60 dBC and 70 dBC acoustic contours for each siren location were obtained by u:1ng the ATI computer model, and superimposed on O 2- g

. s 2.0 INSTRUMENTATION AND PROCEDURES (R.
ALL instruments used for the siren testing and ambient background noise survey comply with the standards set forth by ANSI. The instruments were battery operated and portable. The sound level meters used in the ' field included Bruel & Kjaer (B&K) 2215, 2218, 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, half octave and one-thiro octave filter sets) comply with ANSI S1.11-1966 specifications. Three high precision instrumentation tape recorders were used to i:ollect and store the siren signals and ambient sound Levels at various measurement sites for later detailed Laboratory evaluation and frequency analysis. This procedure was useful in verification of siren tone' f requencies 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 at the end of each recorded tape. ALL recording adjustments made during measurements 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 noted and the appropriate corrections were made to the data. This procedure was followed in compliance with ANSI S1.10-1966 (Calibration of Microphones). fbgrAcoustic TECHNOLOGY INC.
2.1 SIREN TESTING PROCEDURE AND DATA ACQUISITION 0 0 The choice of measuring Locations for the siren testing was made af ter considering seve'ra l 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. These points l 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 pref erred). Typical distances f rom the siren to measuring locations were in the range of 3,000 to 7,000 feet. These distances roughly correspond to average 80 and 55 dec contours for the siren sites. It can be safety assumed that any areas less than 3,000 f eet wiLL be satisfactorily covered by the siren signal. Readings outside of the larger radius are typically covered by other sirens. The measurement Locations for each of the sirens tesced are given in Appendix 1. At each measurement location, all sound level meters were positioned to face in the direction of the siren being tested. Sound Level meters were held at least 4 feet above the ground and 6 feet away f rom any reflective surface (such as a fence or a building). Each microphone was fitted with a wind screen to reduce error caused by wind noise. The measurement procedure followed by the test engineers was in compliance with ANSI l S1.13-1971 (Method for Measurement of Sound Pressure Level) standards. O en 6 y) Acoustic TECHNOLOGY INC.
For each siren test measuring Location, a written description of the site,' A nearby -background noise sources, and the quality of the siren signal were V noted to aid in the processing and analysis of the data. At each location, r :~ the instantaneous direct ' measurement .of an ambient sound Level was conducted both before and after 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. i O ! U Generally, 8 to 12 measuring locations requiring 2 to 3 activations were determined as sufficient to test the acoustic coverage of each siren. However, in the case of isolated sirens with limited road accessibility, the number of measuring locations was restricted and only one siren activation was performed. 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 subsequent activations of the siren. The engineers were then picked up and transported to the next siren where the procedure was repeated. m T)" Acoustic TECHNOLOGY INC.
Because of the Long distances involved, walkie-talkies employing 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 from the portable. control unit. To avoid any adverse community reaction to 1 noise generated by the siren, the activation time was kept to a minimum (approximately 1 to 3 minutes). Two ATI test engineers remained in close proximity of the siren to make additional measurements. One engineer was elevated by a bucket truck to the height even with the centerline of the siren horn, and at a distance of 100 feet from the siren pole. Measurements were made and recorded in this manner fo.- 13 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. The second test engineer stayed on ground level in the immediate vicinity of the siren pole to determine if sound Levels exceeded the 123 d8C Limit specified by NUREG-0654. 2.2 AMBIENT BACKGROUND NOISE SURVEY f The 46 measuring locations for the ambient background noise survey were j selected through an extensive preparation and field investigation process. l These locations are shown on Map 1. As described in FEMA-43, factors considered in this process included population density, ef fects of major transportation routes, and effects of commercial / industrial activities. In addition, areas located outside the predicted 60 dBC siren alert contours were selected among these measuring Locations. 1 0 [h Acoustic TECHNOLOGY INC. w
s For each location, the overaLL ambient sound pressure levels were measured. O) fv These included measurements made with C-weighting, 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 location were noted. These data are presented in Appendix
- 2. These measurements are in accordance with the procedures recommended i.n the FEMA-43 Standard Guide.
In addition to direct measurements, a Nagra IV-SJ instrumentation tape recorder was used to record the ambient sound environment at each location for use in 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. 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 88K 4426 Noise level Analyzer was used to sample the sound Level 10-times per second for the duration of each recorded l measurement. By using linear response recorded tapes, it was possible to l l filter for C-weighted, A-weighted, or various one-third octave bands and t derive the statistical information, i.e. L 90' 50' 10' 'eq, etc. f r each weighting scheme. Results of these anatyaes were obtained through a B&K 2312 Alphanumeric Printer. l 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 spt-trum, with frequency plotted vs amplitude. Knowledge of the e b?M Acoustic TECHNOLOGY INC. D'

l l 4 3.0 DATA REDUCTION AND ANALYSES
/T'.. A T 3.1 SIREN NARROW BWD FREQUENCY ANALYSIS AND SIGNAL-TIME VARIATION ,
Thirteen ~ of the installed WS-3000 sirens in the Waterford-3 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 frequency analyses were performed on both near- and f ar-field siren signal data in order to:
- 1. Determine the exact propagation frequencies of the sirens of the prcept notification system, and
- 2. Study the effects of atmospheric attenuation on the far-field propagation of the spectral components of the siren signals.
t During the analysis, narrow band frequency spectra from the siren signal at 100 feet were obtained. These spectra arc presented in Appendix 3a, and provide information about the harmonic content of each siren tested in the Alert mode. Note that two f requency ranges are presented for the narrow band analysis of Siren 26: 1) 0-2000 Hz, the range which normally encompasses the dominant frequencies (i.e. Lower harmonics) of siren signale for far-field paopagation; and 2) 0-5000 Hz, the range which iliustrates the significance of the higher order harmonics of the siren's h Acoustic TECHNOLOGY INC.

i l e fundamental tone. The higher order harmonics of this siren may be compared with f ar-field data (Appendix 3b) to yield information about siren signal propagation as explained below. A summary of the results of the near-field analyses is presented in the following table.

The overall maximum values measured vary in l l a range of 118 dBC to 124 dBC with an average overall maximum SPL of l 121.3 dBC. The presence of a few sirens with measured maximum SPL's of 118 to 120 dBC had the effect of reducing the average from the rating of 124 dBC. The observed dif ferences in siren output can be attributed to the fact that the tested sirens exhibited deviations in performance because of fluctuations in components such as amplifiers and sound drivers and/or power supply (battery) voltage output drop. 1 O (h) Acoustic TECHNOLOGY lNC. kg! ' [ l !
In addition to determining the acoustical characteristics of the tested
. sirens, the near- and f ar-field narrow band spt tra may be compared to study the effects of attenuation f actors on far-field sound propagation.
For illustrative purposes, near- and fare field narrow band analyses foFi~ representative siren (Siren 26) are shown in Figures 1 and '2, respectively. Both figures are presented with frequency ranges from 0 to 5,000 Hz to compare the relative amplitudes of the higher harmonics and to assess their importance in determining the overaLL SPL of the siren. As shown in Figures 1 and 2, the higher harmonics contribute less to the total. SPL at long distances from the siren, since the relative amplitudes of these harmonics are substantially attenuated at long distances. This effect is f rom the atmospheric attenuation of the higher f requencies, an effect which increases with distance. O It should be noted that far-field sound propagation is dependent on siren signal fundamental frequency. The higher the frequency, the greater the sound propagation loss wiLL be. To illustrate this effect, I the following table is provided. The first column in the table Lists the tone frequencies of the harmonics of a typical siren. The second column Lists the average SPL for each siren tone frequency, obtained from the data in Appendix 3a. The third column Lists calculated valu s for atmospheric attenuation losses for siren signal propagatien at 5,000 feet (assuming the meteorological conditions under which the testing was conducted). Attenuating f actors other than atmospheric absorption are relatively frequency independent, and affect all harmonics equally. O h Acousric TECHNOLOGY INC. M
Since atmc, spheric absorption is the dominant attenuating factor of the higher frequencies, it is considered here for comparison and evaluation - purposes. Tone Frequency Average SPL measured Atmospheric Attenuation Hz at 100 feet (dB) for 5,000 Feet (dB) 795 (fundamental) 122 8 1,590 (second harmonic) 113 le 2,385 (third harmonic) 101 17 - 3,180 (fourth harmonic) 103 28 The above table shows that, on the average, the SPL of the siren signal's . fundamental tone is substantially greater than that of alt its higher ' harmonics, and would also be the least attenuated by the atmosphere. It b
%At would be expected that this frequency will be the dominan'. tona at greater distances. Examination of the data from Appendix 3b confirms this. For example, the difference in amplituce between the fundamenta' and first harmonic in the near-field of Siren 3 is about 9 dB (see Appendie 3a) while in the far-field this difference increases to almost 15 dB (Appendix 3b). The far-field measurements show that the SPL of the func oental tone of each siren tested was considera5ly greater than that 'o' its higher harmonics.

Both near- and far-field values are in accordance with expected values, showing the greater attenuation of the high frequency harmonics. 3.1.1 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 height of the centerline of the siren projector, at a distance of 100 feet. The results are presented in Appendix 4. In addition, the variation of siren signal SPL vs time for siren 13, a typical case, is O shown in Figure 3. The peak levels attained by the tes'ted sirens ranged f rom 118 to 124 dBC. Ideally, the time history curve of the electronic WS-3000 sirens would be a periodic shape with maximum SPL when the siren is facing the measuring microphone. The fact that two maxima occur in each cycle is because the siren horn cluster pauses and reverses direction I once in each cycle. However, a noticeable deviation in curve shape exists l for some sirens. These discrepancies can be attributed to discontinuities in siren performance, probably due to component variations and/or phase l mismatches in the electronic horn drivers. Such irregularities in the siren sound output do not adversely affect the siren system performance or effectiveness. O h, Acous'ic TECHNOLOGY INC

- The graphic Level recordings shown in Appendix 4 also indicate that the g
V WEC WS-3000 electronic sirens tested completed one revolution cycle in 53 to 64 seconds, with a corresponding rotation rate of 0.9 to 1.2 rpm. 3.1.2 Additional Siren Warning Signals lhe WEC WS-3000 sirens used in LP&L's alerting syst'em for the Waterford-3 are capable of producing the Civil Defense and Hi-Lo Warning signals, and the Alert signal previously discussed. The sirens also have a Public Addrest capability. Figure 4 is a schematic description of the f requency vs time dependence of the three warning signals: Alert, Civil Defense, and Hi-Lo. A detailed discussion of each signal is presented below. A representative siren (Siren No- 41) has been selected for illustrative purposes. Civil Defense (Wail) Signal The Civil Defense signal is characterized by a fundamental tone that stays constant in amplitude, but which changes periodically in frequency. Figure 5 presents the instantaneous narrow band spectra of the Civil Defense signals at three separate times to show the range in frequency of the changing fundamental tone. The first, second, and third plots were taken at representative time t , t , and b t (bottom plot) the first e (refer to Figure 4). At time t, fundamental tone was at a minimum value with a frequency of 670 Hz. At time t (upper plot) the tone was at its maximum value of 805 Hz. Time (middle plot) shows the narrow band spectrum for the Civil t' O Defense signal at an intermediate time betweena t and t , with a tone GM r V.%:;; Acoustic TECHNOLOGY INC. m
p f requency of 740 Hz. It should also be noted that the WS-3,000
- electronic sirens can produce a Civil Defense signal ranging as low as 355 Hz and as high as 845 Hz with an adjustable rate of sweep.
Hi-Lo Signal
~
The Hi-Lo signal is similar to the Civil Defense signal but there is an alternating transfer of the acoustit, energy between two fundamental tones, which simulates .a on/off switching of these tones. This alternating switching is illustrated in Figure 6. At
- time t (bottom plot) the first tone fundamental at 400 Hz is "off",
or suppressed, and the second tone fundamental at 528 Hz is "on". This is perceived by a listener as tne "Hi" part of the Hi-Lo cycle. t j After a short interval t, the first tone is "on" and the second tone (at 528 Hz) is "off", resulting in the "Lo" part of the Hi-Lo cycle. Also note that the harmonics associated with either the Hi or lo fundamental tones cycle up and down. This tone alternation occurs throughout the siren sign =L once every .75 seconds. s 3.1.3 Mobile Siren The sound output of the WEC WS-2000 Mobile Siren was measured at a distance of 100 f eet by a test engineer elevated by a bucket truck to the centerline of the siren horn cluster. Figure 7 shows a graphic levet plot ! of sound pressure level (C-weighted) as a func t. ion of time for several modes of siren operation. In the first mode of operation, the Alert mode, the mobile siren produces a constant tone with a fundamental frequency of 785 Hz. As shown in Figure 7, however, the sound pressure level at 100 heAcoustic TECHNOLOGY INC l i
- feet varies considerably over the range of 104 to 111 d8C in this mode.
This variation may be caused by irregularities in the internal components of the siren, and could be eliminated during regular maintenance of the siren. In Wait mode (the Civil Defense signal), the siren's fundamental tone cycles up and down between two frequencies. In the fast Wail mode, these frequencies are 775 and 810 Hz and a cycle is completed in slightly less than one second. In slow Wail mode, the siren's fundamental tone cycles between 650 and 810 Hz once every ten seconds. As shown in Figure 7, the overall sound level of the mobile siren ranges f rom about 100 to 112 dBC in this mode. . m The Growl mode is usually used only as a siren diagnostic tool, Figure 7 U shows that this signal produces a relatively constant level of 109 dBC. Finally, the Hi-Lo Signal consists of an instantaneous alternation between two fundamental tones, 400 Hz and 520 Hz, once every half-second. As Figure 7 shows, the overall sound level alternates between about 110 and 106 dBC in this mode. , On the basis of the above data, it is expected that the mobile siren will l produce an SPL of 110 dBC at 100 feet. For the purpose of estimating the j 60 and 70 dBC sound contours for the mobile siren, a rating of 110 dBC at 100 feet was used as input to ATI's computer model. Since the siren is designed to move along a roadway during activation, the size and shape of the 60 and 70 dBC contours will change as local ground conditions and Ib Acoustic TECHNOLOGY INC. vggp
g topography change. For this reason a set of conservative average ground-conditions was also used as input to ATI's c'omputer model. Table 1 presents predicted SPL values based upon these assumotions. This table
~
shows that the 80, 70, and 60 dBC sound contours wiLL be located roughly 1,200, 1,800, and 2,600 feet, respectively, from the siren position at a given time. The most efficient use of the Mobile Siren is as an auxiliary alerting device, employed whenever primary alerting methods, such as high power fixed sirens, are inoperative. The use of the mobile siren in sparsely populated areas, outside the range of the larger sirens, also can be considered. It must also be noted that the acoustic coverage area of the mobile siren is smaller than that for fixed sirens and, therefore, the mobile siren must be placed sufficiently close to residents to notify them. 3.2 MAXIMUM SOUND PRESSURE LEVEL ACCESSIBLE TO THE PUBLIC One of the criteria established by FEMA for an acceptable siren warning system states that the maximum sound Level received by the public should be no higher than 123 dBC. During the field testing, test engineers standing at ground Level scanned the area around the base of each siren. Maximum siren sound levels (SSL) were recorded at distances in the range o'f 100 feet from the base of the siren poles. The ranges of maximum SSL values for various distances from the pole are plotted in Figure 8. l l l O h) Acoustic TECHNOLOGY INC. w
V c To further ensure that the maximum sound pressure level accessible to the V public will not exceed the NUREG-0654 requirements under any circumstance, analytical predictions were made for aLL of the sirens. Figure 9 illustrates the geometry that was used in the analytical study. Actual-siren height and siren directivity (SPL variation with the vertical angle) were used along with the conservative assumption of hard (reflective) ground. Two receiver locations were considered: 1) at a height of 5 feet above the ground, representative of an individual in the vicinity of a siren; and 2) at a height of 15 ' feet above the ground, typical of an average home in the vicinity of the siren. The predicted SPL variation with distance surrounding the receiver location is presented in Figure 8 for the two heights. The analytical predictions given in Figure 8 show that even the ;h I conservative assumptions were used, the sound level emitted by the siren would be far below the requirements of NUREG-0654. In addition, it is wo.-t hwh i le to note that the analytical predictions and the experimental measurements are in excellent agreement. l l O k (g) Acoustic TECHNOLOGY INC.
p 3.3 AMBIENT BACKGROUND NOISE LEVEL A 3.3.1 Ambient Sound Frequency Characteristics To bett er understand the nature of the ambient sound environment within the 10-mile EPZ of Waterford-3 Steam Electric Station, it is necessary to consider ambient sound f requency characteristics. These characteristics l can be described in terms of standard weighting and filtering schemes, such as C and A weighting and one-third octave band filtering. The j usefulness of each weighting scheme (d8C, dBA) depends upon the frequencies of interest, as each scheme places emphasis upon certain f requencies and de-emphasizes others. The overall SPL at a given point is the Logarithmic addition of SPLs at all frequencies. C-weighting serves to de-emphasize the extreme Low (<50 Hz) and. high (>5,000 Hz) frequencies slightly, while retaining equal emphasis on middle f requencies, as shown in Figure 10. 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 10). Since A-weighting approximates human hearing sensitivity, it is most 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 f requency. Thus, the 500 Hz one-third octave band considers only that sound with O h_@) Acoustic TECHNOLOGY INC. w
r s j f requencies between 447 and 562 Hz. One-third octave band filtering is' o Q useful when only certain f requencies are of interest, such as those near the siren signal frequency. Figure 11 shows the relationship between the one-third octave band SPLs and overall SPL as expressed in d8C. As an example, the one-third octave band frequency spectrum f rom 0 to 2,000 Hz of a typical ambient sound level in a rural area has been plotted in dBC. The Logarithmic addition of all the SPLs of frequency bands from 31 Hz to 2,000 Hz yields an overall SPL of 52 dBC. As shown in Figure 11, the recommended f requency 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 d8 levels at the one-third octave band of the predominant . siren tones are substantially O Lower than the overalL Level, since the Logarithmic sum of all bands must equal 52 dBC. 3.3.2 Ambient Sound Variation With Time
- l Background ambient sound levels vary with time. In the case cf a steady noise source, this variation may be slight. More often, however, ambient conditions are changing at a measuring location, and therefore overatt one-third octave band noise levels may change. Ambient sound level as a function of time for a location with typical traffic activities is illustrated in Figure 12. The dashed curve shows the continuous variation l of C-weighted values which increase and decrease as motor vehicles pass by the measuring location. The solid curve represents the variation of the (Ib Acoustic TECHNOLOGY INC.
w
T A-weighted noise Level with time, and the third curve shows the noise
. variation at the 500 Hz one-third octave band. As described previously, C-weighting takes almost equally all frequencies into account while A-weightirig 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 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.
It should also be noted that the varying ambient sound level at a location may both rise above and fall below the siren signal level. If at some moment 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 impossible to know what the ambient sound Level may be at any
- O particular time during siren activation, it is necessary to review statistical probability distributions of ambient sound levels. One method is to describe the sound in terms of Levels exceeded for a certain percentage of' the time. An L sound level for instance, is the sound n
level exceeded n percent of the time. Thus L ' " 10 exceeded only 10 percent of the time (almost the highest level), L s 50 the sound level ex:eeded 50 percent of the time (the median level), and L is the sound level exceeded 90 percent of the time (almost the lowest 90 are important because most of the varying noise level level). L 10 and L90 remains between these values. In addition, L 90 is often used as a measure of background noise level. O (gb Acoustic TECHNOLOGY IN
, Another way to characterize a varying noise level is to describe it in fd,, 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 , 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 traf fic 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 13. During the measurement, a B&K Noise Level Analyzer was used to sample the varying noise le ve '. 10-times per second, each O 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 *"d '90 wu e c mputed. ey are shown in Ngure 10' 50 13. To depict the range of ambient sound level variation which exists at each measuring location, ATI prepared probability histograms. A typical probability histogram is shown in Figure 14. This histogram corresponds to the noise variation illustrated in Figure 13, and shows the percentage of the samples that fall within certain 2 dB intervals. Thus, 10 percent h,u Acoustic TECHNOLOGY INC. (about:180) of tne 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 woul'd represent a widely-varying ambient sound level.
3.3.3 Definition of Ambient Background Noise Level The alert ability of an outdoor warning siren signal is related to the minimum ambient sound Level that occurs at a listener rite, 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
. systre. "the ambient background noise level should be measured in that one-third octave bandts) containing the. predominant t,one (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 based on the fact that 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 dBC, dBA, and the one-third octave band frequency levels from 315 to 1,000 Hz, as presented in Table 2. However, based on the actual field siren testing, the predominant tones of l sirens were found in the 800 Hz one-third octave frequency band. Although l i direct sound level meter measurements are good indications of the ambient level, the statistical descriptors L10' '50' '90 8"d 'eq provide a more gaccusric recssotoev inc. l l
exact measure of the fluctuating noise level. Tabt'e 2 presents the i summary of the statistical analysis conducted for all measuring locations. A comparison of the direct, instantaneous ambient sound level measurements s with the statistically calculated " ambient levels in Table 2'shows that I approximately 60 percent of the direct measurements fall within the range of the L 10 and L 50 values. Approximately 40 percent are similar to the calculated L ev s. 90 Wban considering the relatively short duration of the peak siren sound signal for a rotational siren which is used in the 10-mile EPZ of Waterford-3, the L val e f the 800 Hz one-third octave band provides an 10 adequate measure of the average outdoor daytime ambient sound Level for the purpose of a conservative design. In additi..., the L value for that eq frequency range could be used as a supplement in areas along major transportation routes where the transient noise is an important factor. This conservative design criteria wiLL have the most influence on the alert ef f ectiveness of the system. Therefore, for the purposes of this verification report, the L 10 8"d 'm values of the one-third octave band of the predominant siren tones are defined as the average outdoor daytime ambient sound levels. 3.3.4 Characteristics of Ambient Sound Environments The acoustic environments within the 10-mile EPZ of Waterf ord-3 Power Station may be classified based upon the character of the background noise sources. These classifications include 1) urban / suburban areas with relatively high population density, 2) rural areas with low population b AccusTic TECHNOLOGY INC. w-
density, 3) commercial / industrial areas, and 4) areas along major transportation routes. It is difficult to classify some areas where several different characteristics of ambient sound are present simultaneo'usly, such as the commercial / industrial areas which exist along major highways. In this report, the most representative and influential ambient sound environment was chosen. However, case-by-case consideration is also given to particular areas. Table 4 summarizes measuring locations, the range and average of ambient sound levels, the proposed criteria for ambient sound levels and typical ambient sources for each acoustic environment category surveyed within the 10-mile EPZ. Each category is described as follows: Urban / Suburban Areas l Both urban and suburban areas have the same character of ambient sound, even though popula. tion density in urban areas is higher than in suburban areas. In this category, the major ambient sound sources are moving traf fic, people talking, radios playing, and commercial activities. Typical examples of areas that belong to this category are Norco (an urban area) Luling, Hahnville, and Paradise (suburban areas). As shown in Table 4, 11 measuring locations fall into this category. At all of these locations, the L values at the 800 Hz one-third 10 ! octave band f requency reveal ambient sound levels in the range of 37 dB to 50 dB and an average ambient sound level of 45 dB. Figure 15 't provides an example of the ambient sound variation with time for a (fhi w Acoustic TECHNOLOGY INC. _3_ l L _.. _- _ . _ _ _ _ _ _ . - _ _ _ _ _ _ - . _ .. -
typical suburban measuring location (M3). The L 10 value f r the 800 t .f m Q Hz one-third octave band is 45 dB. A typical average narrow band frequency spectrum for this category is illustrated in Figure 16. It must be mentioned that although no ambient sound measurements were . made during the survey in Norco, the existing siren system covers this area with a siren signal of at least 70 d8C. It is an adequate conservative estimate, based on typical field measurements, to assume that an ambient sound Level in an urban area would be 10 dB higher than in suburban areas. Therefore, as a result of the consistency in ambient sound levels in these areas, a 50. dBC ambient sound level can be proposed as a system design criterion in i suburban areas, with 60 dBC assumed for an urban area. O Rural Areas Rural areas include f arms and isolated, scattered houses. The bulk of the ambient sound in rural residential area is caused by natural sounds (wind in trees, insects, etc.), and by transient animal sounds * (dogs barking, birds chirping, cows mooing). Six measuring Locations in this category were visited. At these locations, direct one-third octave band measurements show a range of , 30 to 45 dB for the 315 Hz to 1,000 Hz octave bands. From the more detailed statistical analyses, the average daytime ambient sound l I level (L10) ranged from 31 dB to 39 dB at the 800 Hz one-third octave l i O Acoustic TECHNOLOGY INC.

Figure 17 presents a typical example of the ambient sound level variation with time for a rural location (M10). The graphic plot indicates a f airly constant sound level with time, due to less transient noise in rural areas. The typical frequency spectrum for [ this category is shown in Figure 18. Industrial / Commercial Areas Industrial / Commercial areas are those surrounding noisy industrial plants such as oil refineries, grain elevators, and power stations. In these areas, the ambient stuind level is dominated by plant noise and by engine noise from large vehicles servicing the plant. Industrial areas tend to maintaia relatively steady and high noise levels which obscure any natural sound that might be present. As shown in Table 4,14 measuring locations f all into this category. The L values at the 800 Hz one-third octave band have the range of 10 45 dB to 66 dB and the average of 55 dB. Two of these locations (M6 and M7) indicated ambient sound levels higher than 50 dB at 800 Hz one-third octave band. These values, however, were largely influenced by traffic noise on Route 44. Figure 19 provides an example of ambient sound variation with time for a typical industrial constant noise level. Figure 20 illustrates the average narrow band frequency spectrum for this location. dbb) Acoustic TECHNOLOGY INC. W
I Therefore, 60 dBC is proposed as the average daytime outdoor Level to t be used as the general design criterion for the ambient sound Level in industrial / commercial areas. Areas Near Major Transportation Routes: Areas near major transportation routes such as interstate and state highways have ' ambient sound levels which are dominated by the frequent passing of fast-moving vehicles. Near the highways, a relatively constant traf fic flow was observed during daytime hours. Table 4 indicates 15 measuring locations which are classified in this category. Because of the high noise levels of passing cars and trucks, the instantaneous direct measurements indicate a range of 30 to 53 dB for the 315 Hz to 1,000 Hz one-third octave band frequencies. As discussed previously, L may be the more appropriate descriptor for the average ambient sound Level in these areas. This is because the L considers traffic noise as a constant transient noise. eq At atL measuring locations, the L values at the 800 Hz one-third eq octave band frequency indicated ambient sound Levels in the range of 41 dB to 68 dB, ar- an average ambient sound Level of 51 dB. It is noted that only one location (M20), along Route 90 near Boutte, revealed an L,q higher than 60 dB. This is because Route 90 carries a large volume of traffic. Figure 21 presents a typical graphic representation of an ambient sound Level as a function of time for a measuring location near a major transportation route (M18).

Therefore, the general criteria'for the ambient sound. Level in areas near major transportation routes, can be assumed to be 60 dBC. By using the ambient sound level criteria for each category, ambient sound level zones have been developed for the entire 10-mile EPZ of Waterford-3 Steam Electric Station. Four different zones classified with average ambient sound levels of 40, 50, 60 or 70 dB are presented on Map 1. In Section 4.3, the ambient sound level-zones shown on Map 1 will be compared with the siren sound signal to evaluate the effectiveness of the installed siren warning system. It should be noted, however, that the ambient sound levels at each one-third octave band between 400 Hz to 800 Hz are very similar in Table
- 1. Therefore, the ambient sound level zones shown on Map 1 are valid at the 800 Hz one-third octave band, amd also for the range of 400 Hz to 800 Hz. In addition, the anbient sound level zones identified through the ..
survey are conservative estimates of the ambient levels in the one-third octave bands of the siren tones. O kN3 Acoustic TECHNOLOGY lNC. r w~ : I dl
4.0 COMPARISON OF FIELD TEST RESULTS WITH COMPUTER VALUES
%)
4.1 ACOUSTIC COMPUTER MODEL d The siren sound levels within the Waterford-3 Steam Electric Station's 10-mile EPZ were calculated by using the ' ATI acoustic computer moc'el . This model considers meteorological factors, topographical factors, and land surface conditions which affect the propagation of sound generated by each siren, and the acoustical characteristics of the particular sirens involved. The procedures and data that were used to generate the predicted siren sound levels are described in the following sections. Description of Computer Model The most accurate method of obtaining land elevations is by direct i readings f rom USGS maps. Data is read f rom the maps by superimposing a
~
grid system onto the propagation area of the siren (digital terrain tapes are available from the USGS; however, they were found to be inaccurate). This method was used to obtain data used to calculate sound attenuation from barrier ef fects. Other input that was usec in the computer model included the siren mounting height, the siren sound level at 100 feet, atmospheric conditions, and type of ground cover surrounding each of the sirens (i.e. sand, snow, trees, vegetation, water, etc.). The computer model calculates the sound attenuation with distance from these and other factors, which may be summarized as follows: 0 th D' Acoustic TECHNOLOGY INC.
*6 r
A. Hemispherical Wave Divergence: The change in the 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. Tnis i non-dissipative sound pressure level attenuation is a result of the l decrease in energy density (energy per unit area) of the I 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 surf ace area over which the constant energy of the wave is distributed. B. Atmospheric Absorption: Molecular (atmospheric) absorption further reduces the sound O energy. Absorption is highly dependent on the temperature and relative humidity o 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 dirac;ly from USGS maps at various directions and distances f rom the installed siren locations. These conditions were used to calculate the sound attenuation from the absorptive effect of the different ground , coverings. tO (g) Acoustic TECHNOLOGY lNC I _ _ - - - . _ . . ~_, __
, s The primary path of the outdoor sound propagation is the direct n
( line-of-sight path; the secondary path is the ground reflected path. Both of these paths are subject to sound attenuation from the .ef fect of ' ground cover between the sound source and distant locations. In general, five types of ground cover are distinguishable f rom USGS maps for evaluation by the ATI computer model: a) Dense vegetation - forests, mangrove, and thick brush attenuate sound to the greatest extent. b) Wooded marsh - vegetation attenuates sound, but water reflects sound to a certain extent, so attenuation by this ground ccver is not as great as that by denser vegetation. c) Water, marshes - water acts as a reflector for sound propagation, so attenuation over water is very slight. d) Open fields where there is no dense vegetation or other barriers to sound, attenuation is slight. l e) 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 l O g~gaccusric recssoccov inc. 4 act as sound barriers and ' reflection is poor because of high
- A
,, n incidence angles. In urban areas further away from the siren, sound propagates with a low attenuation rate as a result of increased reflection because of the lowered angle of incidence.
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 gradient bend sound rays upward. Dcanwind, the sound rays are bent downward and no shadow zone is produced. Crosswind, there is a zone of transition. I i E. Barrier Attenuation Effects: A mound of earth, a hill, or a structure, if Large enough, is a partial barrier to sound and can provide a moderate amount of sound l
- reduction within its shadow zone.
l l The sound attenuation caused by a barrier is calculated by the 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. O l g) Acoustic TECHNOLOGY INC
l I Topographical data from USGS maps are used by the computer model to
' calculate the sound attenuation from barrier effects caused by the high elevations generating acoustic shadow zones behind ridges and hills.
4.2 CORRECTIONS TO FIELD MEASUREMENTS s For purposes of comparison with the actual siren SPL measurements, corrections for meteorological conditions as well as the dBC to dBA conversion were made to the computer predicted SPL values. The data summary tables in Appendix 6 include temperature, relative humidity, wind speed and direction for the day and time of each individual siren test. Hourly reports of the ambient temperature, relative humidity, and wind ( conditions for each test day were obtai'r,ed from the National Weather Service office at the New Orleans International Airport. Subsequently, ATI's computer model was used to predict siren sound levels based on the specific meteorological conditions recorded during the siren tests. Further, for each tested siren, the sound level output measured at 100 feet from the siren was used as one of the 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 dif ferences was performed. To ensure the accuracy of this analysis, the O thl) wr Acoustic TECHNOLOGY INC _ . _ _ _ _ _ _ _ _ _ _ ~ , ______ _ . . _. _ . . . _ . _ _ __ _ _ _ _ _ _ _ _ _ _ _ . _ _
7,, 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 3 the'seven follobi.ng conditions:
- 1) An acoustic barrier effect 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, behind a smaLL hill, etc.
- 3) A sudden and sporadic wind or atmospheric effect I
causing large variation of the siren signal.
'O 4) Disagreement due to factors not shown on USGS maps.
- 5) Interference of audible siren signal by passing traffic.
- 6) ' Failure of siren signal to rejis:(i above the amb'ent noise level.
- 7) Equipment or huoan error, e.g. weak batteries, incorrect meter readings, etc.
A histogram depicting the differences between the predicted and the measured SPL for the tested sirens, alor.3 with the average and the standard deviation, is given in Figure 23. The average difference between the predicted and measured SPL ealues is -0.21 dB. This indicates an exceltent () correlation between the computer model and the actual field measurements. a (K) m, Acoustic TecHNOLOC/ lNC.
~~
'It should also be noted that the negative value for the average indicates slightly conservative predicted values. Since -0.21 dB is less than the precision of the sound level meter Q 1 dB), it can be concluded that the computer.model is a very accurate prediction metho'd. The standard deviation, which is a measure of the typical fluctuation of the test values about the predicted values, was calculated to be 2.18 dB.
Figure 24 shows a plot of the predicted levels versus measured levels for all of the sirens tested. The dashed line at 45 degrees is the line of perfect agreement, where points to the right of the line were predicted above measured values and points to the left were predicted below. These data show a very close correlation, implying good agreement between measured and predicted values. It should be noted that the points around 60 dBA are generally to the left of the -45 degree line, indicating the O slightly conservative nature of the predictions. A plot of the differences between predicted and measured SPL values vs distance from the siren is shown in Figure 25. Ninty-one percent of all differences are within + 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 of about 5,000 feet from the siren, this
- portion of the plot should be considered. Most distances further than 5,200 f eet show measured values greater than predicted values, once more emphasizing the conservative nature of predictions at great distances from the siren.

)
The data collected during the siren field testing documents the acoustic output.of the installed.WS-3000 sirens to be 122 d8C at 100 feet from the centerline of the siren projector. Also, narrow band frequency analyses of the measured output for the installed sirens indicate that the fundamental tone frequency of 800 Hz. Therefore, the ATI acoustic computer model was used to generate the 60 and 70 dBC siren coverage for the installed sirens based on these data. The extent of the siren coverage for the 42 installed sirens is shown on Map 2. As a result of the slightly lower siren output than the design specifications and the higher fundamental frequency, some areas are outside l of the adequate siren alert coverage. Therefore, adjustments will be l O performed on the installed sirens by the siren, manufacturer to provide an l i optimal f requency of 500 Hz for the sirens. As described previously, tht-lower frequency is known to be more effective for the far-field sound propagation. i The demographic distribution of the EPZ was evaluated through USGS maps, I aerial photographs and actual site inspection. Based on this evaluation, the siren coverage analysis, and the results from the ambient survey; additional siren locations were recommended to ensure that all populated areas within the EPZ receive an adequate siren alert signal. 9 Acouric TECHNOLOGY INC. n

SLNWIARY Louisiana Power & Light Company (LP&L) contracted Acoustic Technology, Inc. (ATI) to verify, field test, and evaluate the acoustic coverege of the alert / notification system installed within the plume exposure pcthway Emergency Planning Zone (EPZ) of the Waterford-3 Steam Electric Station. This study is a supplement to Volume I: Analysis, Verification, and Testing of the Siren Prompt Notification System for Waterford-3 Steam Electric Station, submitted March 1984. Volume I and this study (Volume II) document the adequacy of the alert warning system in meeting 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, Rev.1 and The Standard Guide for the Evaluation of Alert and Notification Systems for Nuclear Power Plants (FEMA-43): September 1983. O The primary alert system of Waterford-3 is provided by 51 highpowered rotational electronic sirens rated 124 dBC at 100 feet, one non-rotating siren rated 106 dBC at 100 feet, one mobile siren, and four helicopters equipped with battery-operated electronic sirens. Volume I describes the analysis and evaluation of the original siren warning system. Based upon the results of this evaluation, LP&L installed nine additional sirens to supplement the acoustic coverage of the original system. To alert unnotified transient population in the wetlands of the EPZ, four
~
helicopters equipped with electronic sirens with public address capability will be used as a special alerting method. l O g Acoustic TECHNOLOGY INC.
In this report (Volume II), the additional sirens and helicopter alerting V(3 system were tested and evaluated to verify the effectiveness of warning notification to the entire EPZ. In addition, the siren warning system (fixed sirens) within the 10-mile EPZ of.the Waterford-3 station was activated to evaluate the total effectiveness of the fixed siren system. The testing of several newly installed sirens indicated that siren sound pressure levels predicted by the ATI computer model were in excellent agreement with actual field measurements. As in Volume I, the siren testing results showed that the computer model is an accurate, slightly conservative, predictive model. The locations for the siren monitoring / total activation testing were chosen to document the adequacy of the siren acoustic alert system by testing areas of high ambient noise or areas near the f ringes of acoustic cove' rage zones within the lower levels i of siren sound contours (see Map 1). The results showed that in all tested areas in both St. John the Baptist Parish and St. Charles Parish, the siren acoustic coverage provided an adequate alert signal. For wetland areas with possible transient population outside the adequate siren coverage of the 51 highpowered sirens within the 10 mile EPZ, four helicopters equipped with electronic sirens were used to~ transmit a message and an alert tone through a loud-speaker / amplifier system to alert transient populations. This mobile alerting system was tested to determine the optimal conditions for the operation of the system. Various parameters affecting the system operation were tested. These parameters include flight attitude and flight speed. Based upon the results obtained from O Acoustic TECHNOLOGY INC.
d field testing, the system design parameters for the helicopter flight of 500 feet in altitude and 60 miles per hour (mph) in flight speed were determined to be optimal and adequate. Based on the evaluation and verification of the warning system described in Volumes I and II,-it'was determined that the entire 10-mile EPZ was adeqt.ately covered by the alert / notification system.

. Agency. (FEMA) require that public notification systems instal-led within the 10-mile EPZ of nuclear power plants are tested to ensure compliance with NUREG-0654 and FEMA-43. The objectives of the testing are to accurately determine the siren system performance, and to verify that the complete alert / notification system is adequate and capable of alerting the public within the nuclear power plant EPZ.
The Waterford-3 primary prompt notification system includes 51 electronic rotational sirens model WS-3000 manuf actured by Whelen Engineering, one WS-2000 model siren, one mobile siren, and four helicopters equipped with r i electronic sirens. As described in Volume I, the original siren warning system was designed with 42 electronic sirens. Based upon the siren field testing, the ambient noise survey, and the computer analysis of siren signal propogation, the siren warning system was improved with nine additional sirens, for a total of 51 highpowered electronic sirens to provide an alert signal for all inhabited areas within the 10 mile EPZ. l For w.etlands and takes where transient population is expected, four l helicopter airborne warning systems are used. In July and August 1984, a team of consultants and engineers from ATI conducted additional field testing. This field testing program included:
- 1. Field evaluation and testing of the helicopter airborne warning system.

- 2. Field testing of newly installed sirens.
- 3. Monitoring and testing of a total siren activation.
All field testing and measurements were performed independently -by ATI's engineers with assistance from LP&L and local civil defense personnel. Testing procedures, data acquisition methods, and data analyses are described in subsequent sections of this report. All instrumentation used for the field testing meets standards set by the American National Standards Institute (ANSI) and any other applicable standards. This report, Volume II, is divided into three topics related to the evaluation and performance testing of the primary prompt notification system. In Section 2, a description and evaluation of the helicopter airborne warning system will be presented. In Section 3, field testing for newly installed sirens will be discussed.

- 2. O EVALUATION AND TESTING OF THE HELICOPTER AIR 90RNE WARNING SYSTEN b)
V , 1 The helicopter airborne warning system has been implemented to provide j alert / notification to any transient population expected in wetlands and Lake areas in the 10 mile EPZ. These areas are located outside the alert I signal acoustic coverage provided by the siren warning system. FEMA-43 I specifies that helicopter airborne warning systems are one o.f the special alerting methods. This method wiLL provide adequate alert and notification for the transient population within the 10-mile EPZ of Waterford-3. 2.1 SYSTEM DESIGN The airborne warning system consists of four helicopters equipped with an amplifier / Loudspeaker, model STS-400, rated at 250 watts and manufactured O by Applied Electro-Mechanics, Inc (AEM). The alert message transmitted f rom this system is pre recorded on an endless loop tape to ensure accuracy , and consistency with the information transmitted to the public. Figure 1 presents a schematic illustration of the helicopter airborne warning system and mounting orientation of the amplifier / Loudspeaker with respect to the helicopter. The use of four he'.icopters, in case of a nuclear emergency at the Waterford-3 Steam Electric Station, was arranged with Air Logistics, Inc. of Belle Chasse, Louisiana. This system was designed to cover the entire wetland and Lake areas within the 10-mile EPZ within 45 minutes by means of four helicopters. Each helicopter flies at an altitude of 500 feet and at O ggacousTic recssotoav isc.
a speed of 60 mph. Based on the information obtained from the manufacturer of an amplifier / Loudspeaker it was calculated that the message f rom this - warning system would be clearly audible at a 1/2 mile range from the helicopter in both directions. Map 2 shows the helicopter flight routes which satisfy the time constraint of 45 minutes with a speed of 60 mph. The total time estimates for alerting each quadrant of the EPZ are between 38 ' minutes and 44 minutes. In all quadrants, all areas within 5 miles are covered within 15 minutes. To verify the system design criteria for flight speed and altitude, and range of notification coverage, the acoustic field testing for the helicopter airborne system was performed as discussed in the following sections.

l 2.2 TESTING PROCEDURES AND DATA ACQUISITION On July 30 and' 31,1984, ATI performed acoustic testing of the helicopter airborne warning system. The scope of the testing included determination of the flight parameters for optimal alert coverage of the helicopter airborne system. For these tests, two dif.ferent sound sources were transmitted from the helicopter loud-speaker system. The first source contained a voice alert message of approximately 15 seconds duration, which stated "this is a test of the helicopter alerting system." This was used to test and verify the dependence of the intelligibility of the message on flight parameters. The second source was a known pure tone with 500 Hz O
@ ACOUSTIC TECHNOLO l
fundamental f requency and a duration of 15 seconds which was used to test (VO characteristics of sound propagation from the helicopter warning system. The testing set up is shown in Figure 2.' ATI engineers were located at the-measurement locations, M1 through MS, shown in the schematic. The alert message and signal were transmitted only while the helicopter traveled in one direction to maintain consistency in the testing conditions. Flights at various altitudes and speeds were conducted. Altitudes of 250, 500, 750, and 1000 feet were tested. Flight speeds tested were 30, 45, 00, and 120 mph. For all flights, the orientation of the loud-speaker horn was fixed at an angle of 15 degrees f rom the horizontal, the optimal angle for sound propagatiori. t l ATI engineers performed measurements on all of the flight tests using precision tape recorders and calibrated sound level inete rs. The tape recorders used were two Sony TCM 5000's, a Nagra IV-SJ, a Nagra IV-SN, and a Bruel and Kjaer (B&K) 7005. The sound level meters were all B&K, two typa 2230, two type 2215, and one type 2218. Recordings were made for the entire duration of each flight. A calibration tone was recorded at the beginning and end of each tape, and all recording adjustments were noted. At the beginning and end of the day, all equipment was checked and calibrated. Any variance from proper calibration was noted and the appropriate corrections were made. This procedure was followed in compliance with ANSI S1.10-1966 (Calibration of Microphones) and the recording system setup was in compliance with ANSI /SAEJ184 (Qualifying a Sound Data Acquisition System). O (gp RM Acoustic TECHNOLOGY lNC.
2.3 DATA REDUCTION AND ANALYSIS The ATI engineers analyzed the tapes recorded during the helicopter flights. The analysis consisted of three parts. The first determined the optimal flight altitude for sound propagation f rom the helicopter airborne warning system. The second part examined the dependence of flight speed on sound propagation from the helicopter. The third part of the analysis tested and verified voice intelligibility for messages transmitted f rom the helicopter warning system. Particular attention was focused on the intelligibility of the messages transmitted at the speed and altitude determined as optimal in parts one and two of the analysis. To verify that the test signals were not propagating distortedly to the measurement locations, frequency spectra were made for each signal used. O Figure 3 shows the spectrum of the first test signal, a known pure tone , spectrum, taken from the source tape and also taken f rom the tape recorded at measurement location 5. Similarly, Figure 4 presents two spectra of the voice message, one taken f rom the source tape and the other taken f rom a tape recorded at measurement location 3. The same characteristic spectra of the original tapes are evident at the f ar-field measurement location indicating that the test signals were propagating undistortedly to these locations. The purpose of these comparisons was to determine major spectral changes from propagation through the atmosphere, and the ef fects of sound source movement. O

2.3.1 OPTIMAL FLIGHT ALTITUDE DETERMINATION k Part one of the helicopter airborne warning system analysis determined the optimal flight altitude for sound propagation. Flight alt-itude.is the most important parameter for determining the projected area of sound coverage. Because of the angle of the siren horn, altitude has a profound ef fect on the distance that the sound will travel, and on the area over which the most audible sound levels are distributed. Figure 5 shows the effects of flight altitude on signal propagation. While the propagation distance and the coverage area both increase as the altitude is increased, the sound level is attenuated as propagation distance increases. An optimal altitude for signal reception can therefore be determined, depending upon the parameters of the warning system setup. l Using the original tapes as primary data, sound pressure level (SPL) time variation charts were generated using a B&K Level Recorder Type 2306. These charts present the amplitude of the recorded signals in the 500 Hz 1/3 octave band. This is the frequency band that contains the fundamental frequency of the known pure tone signal used in this portion of the testing. By calculating the amount of time that the SPL of the projected l signal exceeded the ambient background noise (including helicopter noise) l by 9 dB, the number of messages audible from the helicopter's flight pass was determined. A standard message was set at a length of 15 seconds. Figure 6 shows two samples of the time variation of the signal audibility, showing where the test signal exceeds the ambient noise level by at least 9 dB. The factor of 9 dB was chosen because the human ear can readily Acoustic TECHNOLOGY INC. I
distinguish tones when they are 9 d8 or more above the background noise h (Q Level. The background noise level was determined by measuring the SPL when the known signal was turned off. For each altitude and each measurement location the results of this analysis produced a measurement of the signal's audibility. The results are presented in Figure 7. For locations approximately 2000 feet f rom the point below the helicopter's path, ea:h altitude yields about the same result for sound signal propagation. However, at distances greater than 2000 feet, altitudes of 500 to 750 feet yield much improved sound signal propagation. The mounting orientation of the siren horns causes this long range effect. (See Figures 1 and 5). For distances less than 1000 feet, the audibility is not as ef fective a:. O those at longer distances because of the directivity and the orientation of the helicopter loudspeakers. For locations directly below the helicopter's flight path, the audibility improves because of the shortening of the signal path length and the reinforcement of the sound signal by two banks of horns, instead of only one when the helicopter passes to the side of the listening location. Flights at an altitude of 1000 feet were also' tested, but it was found that this altitude does not provide adequate signal propagation over the range of distances being considered. These results determined that a flight altitude of 500 to 750 feet will optimize the sound signal p opagation over the desired system design distances of about 2500 feet (or 1/2 mile). O We) Acoustic TECHNOLOG
s 2.3.2 OPTIMAL FLIGHT SPEED DETERMINATION t') NJ The second part of the helicopter airborne warning system analysis determined the effect of flight speed on sound propagation. The directivity of the sound emitted by the loud speaker horn results in Listeners at farther distances' hearing a given signal for a longer period of time. Since the signal wilL spread out as it propagates from the ' helicopter, Listeners at far locations wiLL hear both a longer and a weaker signal. Optimization of the flight speed is possible by analyzing the test data collected. For each test, the total number of seconds for which the known signal exceeded the ambient noise level by at least 9 dB was computed for each f-s flight. Since the test signal length was 15 seconds (for both the known s tone and the voice message), the number of messages that were audible during each test period, and thereby the number of audible messages corresponding to each flight speed were determined. Various speeds were tested at the fixed test altitudes of 250, 500 and 750 feet. The results for the different flight speeds with a fixed altitude of 500 feet are shown in Figure 8. The audibility of t'he signal during the 30 mph flight is excellent. The 45 mph flight speed provides very good tudibility. Also, the audibility of the signal during the 60 mph flight was good. Flights t 120 mph were also tested, however these proved to be inadequate for alerting purposes. At 120 mph, the helicopter travels too quickLy to allow the listener to receive a sufficient number of audible messages. G (gg) Acoustic TECHNOLOGY INC. v
)
Figure 8 indicates that a slower flight speed provides the Listener with a longer time period to hear several messages, since the flight time is longer. However, since the time allowed for the helicopters to cover their preassigned areas is restricted to 45 minutes or Less, the helicopters must travel at 60 mph. Figure 7 indicates that for propagation, the audibility of the 60 mph flight is adequate over the design coverage araa. In addition, this analysis only examines one test period of closest approach. In actual use, it is clear that listeners wiLL hear more messages than those contained in one helicopter pass. Thus, a flight speed of 60 mph is sufficient for alerting purposes and meet.s the design specification for the helicopter flight routes which must be covered within 45 minutes. 2.3.3 INTELLIGIBILITY OF VOICE MESSAGE The third part of the helicopter airborne warning system analysis focused l on the intelligibility o,f the voice message. Table 1 shows the intelligibility rating given to each test flight for the various sets of parameters. These ratings were derived by a direct analysis of the recorded tapes. While intelligibility and audibility are closely related, intelligibility depends on many f actors. These factors include signal to noise ratio, repetition of the message, and attention of the Listener. The ! intelligibility results illustrated in Table 1 confirm the conclusions reached in the analysis discussed above. For the flights at 250 feet, the intelligibility of the voice message at the far locations is poor for each of the flight speeds. At a flight altitude of 500 feet flight speeds of 30, 45, and 60 mph produce good ($$h
' :gy Acoustic TECHNOLOGY INC.
intelligibility at aLL Listening locations. At 500 feet ' and 120 mph the intelligibility everywhere is poor. For a flight altitude of 750 feet the 4 intelligibility is good for all flight . speeds and Listening locations. The one test performed at a flight altitude of 1000 feet indicates that for this altitude intelligibility is peor at all locations under investigation. l 2.4 EVALUATION OF HELICOPTER AIRBORNE WARNING SYSTEM The testing and analysis of the helicopter warning system verified the system design criteria of a flight altitude of 500 feet and a flight speed of 60 mph. These flight parameters provide adequate audibility and - l intelligibility of the warning message over a range of at least 3300 feet. i This range exceeds the original design criteria of 1/2 mile and provides a O Large safety margin for the warning system coverage. At speeds of 60 mph, Listeners 1/2 mile f rom the helicopter should hear at least three clearly audible warning messages of 15 second duration for each nearby helicopter pass. The messages should be easily intelligible at 1/2 mile for an altitude of 500 feet and speeds near 60 mph. I It is recommended that the taped voice warning message begin with a pure tone signal. Voice message intelligibility testing indicated that l Listeners who were alerted to the upcoming voice message by a pure tone i signal, better understood the content of the voice message. i l 1 11- W1 AccusTic TECHNOLOGY INC.

3.0 FIELD TESTING OF NEWLY INSTALLED SIRENS 3 (V Volume I of this report documents the verification of the acoustic coverage for the original warning system consisting of 42 highpowered rotational sirens. Based on this earlier study, nine additional sirens were installed to completely provide the full acoustic alert coverage to aLL populated areas within the EPZ. This volume describes the field testing procedures and resu'.ts used to evaluate the effectiveness of the nine new sirens in supplying the necessary acoustic coverage. Map 3 in Volume I shows the composite acoustic coverage of the 60 and 70 d8C siren alert signal, based upon a computer model developed by ATI for the entire system with 51 highpowered sirens. The additional sirens were tested by conducting near- and far-field measurements of the SPL from a sample of these sirens, q and by comparing the test results with the predictions generated by the ATI V computer model. It was found that the predicted and measured siren SPL's were in good agreement, and that the additional sirens provide the required supplementary coverage for notification of the populated areas within the Waterford-3 Steam Electric Station EPZ. 3.1 FIELD TESTING PROCEDURES AND DATA ACQUISITION Ref er to Volume I, Section 2 of this report for a description of the instrumentation procedures and choice of measurement locations for siren i field testing and the ambient noise survey. For the field testing of the newly installed sirens, eight far-field measuring locations requiring two activations were generally deemed suf ficient to test the acoustic coverage of each siren. However, in the case of isolated sirens with limited road
-,2-g Acoustic TECHNOLOGY INC.
accessibility, the number of measuring locations was restricted and only l one siren activation was performed. The measurement locations for the ; 1 newly tested sirens are given in Appendix 1A. ' c-At each location, the instantaneous direct measurement of an ambient sound level in dBA-scale was taken to determine if the background noise might influence the observed meter reading of the siren signal. A written description of the test site, including nearby background noise sources and the quality of the siren signal, was not'd e to aid in processing and analyzing the data. At selected sites, high precision instrumentation tape recorders were used to collect and store the siren signals for later detailed Laboratory evaluation and frequency analysis. This procedure was useful in the verification of siren tone f requencies and siren tone effectiveness in far-field sound propagation. In addition to the far field measurements, an ATI test engineer took hand-held and tape recorded readings 100 feet from the siren pole on the ground and (when available) from a bucket truck at a height of 50 feet. These measurements were used to verify the siren sound output rating, and to record data to be used for narrow band f requency analysis of the siren signal. In addition, this data was useful in ensuring that the siren sound levels did not exceed the 123 dBC Level specified by NUREG-0654. 3.2 DATA REDUCTION AND ANALYSIS l Six of the newly installed WS-3000 sirens were randomly selected for testing. Near-field measurements were made for three sirens out of six (SD qg Acoustic TECHNOLOGY INC.
selected sirens 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. Also, narrow band frequency analyses were performed on both near- and far-field siren signal data. Appendices 18 and 1C contain the siren spectra. A summary of the results of the near-field analyses is presented in the following table. MAXIMUM SOUND PRESSURE LEVELS (SPL) AT 100 FEET: ALERT MODE SIREN SIREN TONE: FUNDAMENTAL SIREN TONE: FIRST HARMONIC OVERALL NO. FREQUENCY (Hz) SPL (d8) FREQUENCY (Hz) SPL (dB) SPL (dBC) 48 490 118 980 104 118 49 585 122 1170 106 122 49 585 122 1170 109 122 50 490 121 980 107 121 ! O ' Based on the field data obtained, the newly installed sirens produced a fundamental tone f requency in the range of 490 to 585 Hz in the Alert Mode. The overall maximum SPL varied from 118 to 122 dBC with an average overall maximum SPL of 120.8 dBC. These values are comparable with the results obtained by the first siren test performed in November 1983 as described in Volume I. The observed differences in siren output can be attributed to normal deviations in the performance of the sirens, such as fluctuations in amplifiers and power supply output voltage drop. Note that the fundamental tone and harmonics of siren 49 are not fixed in frequency, but have a relatively wide spread. This was noted at the time of activation and LP&L has corrected this siren performance deviation. O , fhw Acoustic TECHNOLOGY INC
s The near- and far-field narrow band spectra presented in Appendices 18 and n U 1C can be compared to study the effects of attenuation factors on far-field sound propagation. Figures 9 and 10 illustrate a representative set of near- and far-field narrow band frequency spectra. Both-figures are - presented with frequency ranges from 0 to 2000 Hz to compare the relative amplitudes of the fundamental tone and the first few harmonics, and to assess their importance in determining the overaLL siren SPL. The sound propagation in the far-field is dependent on the fundamental f requency of the siren. The higher the f requency, the greater the sound propagation loss wiLL be. This is discussed at length in Volume I, Section 3, where it is shown that the SPL of the siren signal fundamental tone is substantially greater than that of all its higher harmonics, and is also the least attenuated by tne atmosphere. This frequency is, thus, the O dominant tone at greater distances. Examination of the data from Appendices 18 and 1C confirms this for the newly installed sirens. The far-field measurements show that the SPL of the fundamental tone of each siren tested was considerably greater than that of its higher harmonics. This is also evident when comparing Figures 9 and 10. 3.3 COMPARISON OF FIELD TEST RESULTS WITH COMPUTER PREDICTIONS Volume I, Section 4 of this report details the ATI acoustic come .er model used to calculate siren sound propaga't ion. At each far-field measurement location hand-held measurements of sound pressure in dBA scale were taken and later compared to the analytically predicted sound pressure level values. Data summary tables for individual siren testing are included in
-,s-g Acoustic 'TECm%Y WC.
Appendix 1D. A statistical analysis of the differences between the n V, measured and predicted sound levels was performed. To ensure the accuracy of this analysis, only field measurements which were not unduly influenced by local effects were used. Measurement-data values were not considered in the comparison between measured and predicted values if they were affected by any of the seven following conditions:
- 1) An acoustic barrier effect 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, behind a small hill, etc.
g 3) A sudden and sporadic wind or atmospheric effect causing a large U variation of the siren signal. l
- 4) Disagreement from factors not shown on United States Geological Survey (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) Equipment or human error, e.g. weak barriers, incorrect meter readings, etc.
i t A histogram showing the differences between the predicted and the measured SPL for the tested sirens, along with the average and the standard deviation, is given in Figure 11. The average difference between the predicted and reasured SPL values is -0.4 dB for the newly tested sirens. This indicates an excellent correlation between the computer model and the g) Acoustic TECHNOLOGY INC i9
actual measurements. It should also be noted that the negative value for the average indicates slightly conservative predicted values. Since -0.4 dB is less than the precision of tne sound level meter (+ 1 d8), 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 1.96 de. In addition, this statistical evaluation for comparison between the measured and predicted SPLs was performed for aLL sirens which were tested in November 1983 and in August 1984 Figure 12 shows a histogram for a total of 96 data points for all tested sirens. The average difference between the predicted and measured SPL values is
.27 dB and its standard deviation was determined to be 2.19 dB. Again, this statistical analysis indicates the accuracy and conservative nature of the computer model.
O 3.4 EVALUATION OF SIREN SYSTEM DESIGN COVERAGE WITH FIELD TESTING R The data collected during the siren field testing documents the acou. ic i output of the newly installed WS-3000 sirens and demonstrates good agreement with the ATI computer predicted values. Also, narrow band frequency analyses of the measured output for the new sirens indicate an f average fundamental tone frequency of 513 Hz. This frequency, as described previously, is known to be more ef fective for far-field sound propagation than a higher frequency (800 Hz). Volume I of this report documented the acoustic coverage of the original 42 siren system within the plume exposure pathway EPZ of the Waterford-3 Steam AccusTic TECHNOLOGY lNC. m
Electric Station. At that time, it was reccomended that nine additional sirens be installed to provide a system capable of notifying 100 percent of , the public within the 10-mile EPZ. The current study verifies the validity l of the predicted sound Levels f rom .these new'ly . installed sirens,.' ensuring that the final system design does provide sufficient and complete acoustic Coverage. i P l O I I O

4.0 RONITORINE AND TESTING OF TOTAL SIREN ACTIVATION O . The purpose of the total activation tests within the EPZ of Waterford-3 Steam Electric St'ation was to determine the performance of the sound propagation of all the sirens operating simultaneously. Four total siren activations, two at St. John the Baptist Parish and two at St. Charles Parish, were monitored at five locations each for a total of 20 siren monitoring locations. Map 1 shows the 20 field measurement locations along with the positions of the installed sirens. The measurement locations were strategically chosen to lie on the edge,s of the 60 and 70 d8C siren sound propagation contours generated by the ATI computer model. This was done so that the measured siren signals would be significant to the evaluation of critical areas. In addition, the measurement sites were located in areas of relatively high ambient background noise to ensure a more conservative estimate of the siren signal coverage. 4.1 DATA REDUCTION AND ANALYSIS At each monitoring location, descriptions of the test site, nearby noise sources, and readings of the ambient noise level were made. The siren signals were recorded on tape in Linear scale for Laboratory analysis. The recorders used were two Sony TCM 5000's, a Nagra IV-SJ IV, a Nagra IV SN , and a B&K 7005. The sound level meters used were two B&K 2230's, two B&K i 2215's and one B&K 2218. ALL equipment and instrumentation procedures for recording were the same as those described in Section 2.2 of this report. i O hwACOUSTIC TECHNOLOGY INC l l
e In the lab, the recordings of the siren signals were first analyzed through O Q a Narrow Band Spectrum Analyzer, B&K Type 2031, to determine the frequency characteristics of the activated sirens. The type of signal used in the total activation tests was the Civil Defense (Wail) signal. .The Civil Defense signal is characterized by a fundamental tone that stays constant in amplitude but which changes periodically in frequency. The WS-3000 electronic sirens can produce a Civil Defense signal ranging as low as 355 Hz and as high as 845 Hz with an adjustable rate of sweep. A sample frequency spectrum, from location SC-4 during the first total activation at St. Charles Parish, is shown in Figure 13. This figure shows that the siren signal ranges f rom about 350 Hz to 850 Hz, as expected. The frequency spectra for each activation are in Appendix 2A. - Once the f requency characteristics of the Civil Defense signals were O established, the tape recorded siren signals were run through a Graphical Analyzer, 88K Type 2306, af ter being appropriately filtered - so that only the frequencies of interest were examined. To evaluate the entire 355-845 Hz range of the Civil Defense signals, the recordings taken at each , location were graphically analyzed twice, once with 500 Hz full octave band filtering C requency range: 355-710 Hz), and once with 1000 Hz full octave band filtering (f requency range: 710-1420 Hz). Thus, two time variation charts showing the siren signal SPL as a function of time with the appropriate filtering schemes were produced for each monitoring site. Figure 14 shows a sample pair of SPL-time variation charts for the first St. Charles Parish activation at location SC-4 Appendix 28 contains the SPL-time variation charts for all measurement locations. i O

we f
To determine the audibility of the total activation signals, the SPL-time V' variation charts were examined to determine the percentage of time that the SPL was above a certain base level. This base level was chosen to be 10-de above the ambient background noise level that characterizes the region in which each site Lies. Refer to Map 1 and Section 2.2 in Volume I of this report for a description and discussion of the ambient noise within the EPZ of the Waterford-3 Steam Electric Station. For example, location SC-4 Lies in a region of 40 dB average ambient noise, so that 50 dB was chosen as a baseline, which is shown in Figure 10. During the 152 second recording, the SPL in the 500 Hz full octave band was above the 50 dB baseline for 137 seconds, and the SPL on the 1000 Hz full octave band was above the baseline for 108 seconds. It is important to note that the time during which the S?L was above 50 de for its full active f requency range is not a simple summation of these two times, since such a sum would contain " overlaps" where the SPL in both f requency ranges exceeds 50 dB simultaneously. When l these overlaps are considered, the SPL for the full siren f requency range exceeds the 50 de base line for 144 seconds from a total of 152 seconds or 95 percent of the time. This indi ates excellent siren audibility at i Location SC-4 considering the low ambient noise level. 4.2 MONITORING RESULTS Descriptions of the test site, siren signal, nearby noise sources and the siren signals are recorded on the data sheets in Appendix 2C. The SPL time variation chart recordings of the filtered siren tapes with the sound level baselines superimposed are shown in Appendix 28. The results of the SPL time variation chart analysis are displayed in Table 2. If the siren
-2,-
g) Acoustic TECHNOLOGY INC
3 signal level exceeds the baseline at least 50 percent of the time, audibility is considered excellent, 20 to 49 percent of the time is considered good,10 to 19 percent of the time is considered fair, and 0 to f-9 percent of the time is ~ considered poor. Refer to Map .1 for site locations. The results can be summarized as follows: St. Charles Parish Activations Location SC-1 was inside a Landfill, a good distance from Route 61 just outside the edge of the 60 de contour for siren 36, the predominant siren. The background ambient noise level at this site is 40 de, and 44 seconds out of 176 seconds total activation, or 25 percent of the total activation time, the siren signal level exceeded 50 de, indicating good audibility. The maximum siren signal level was just under 60 dB, in close agreement with the predictions made by i O the ATI computer model,. t 1 - Location SC-2 was by a schoolhouse off Route 48 on the edge of the 70 i de contour between sirens 14, 35, and 36. In spite of the high ambient noise level of 60 dB produced by traffic and industrial activity, aLL three sirens were clearly heard. In fact, for 37 percent of the activation time, the siren SPL exceeded 70 dB, for
, good audibility. The siren signal level actually peaked above 80 de, I
l higher than the predicted estimate of 70 dB. This difference can be j attributed to the three sirens acting "in phase" and mutually i reinforcing their signals. i l O l .

Location SC-3 was by the railroad tracks off Route 626 at the edge of l A V the 60 dB contour for sirens 14, 35, and 36. The predominant sirens 14 and 35 were clearly audible, although siren 36 could also be h e a r d .. .The 60 dB. ambient noise was largely due to wind, Loud crickets, and Route 626 traffic. Audibility was rated as f air since the siren signals were above 70 dB for 23 seconds, or 13 percent of the time. Location SC-4 Lies '1/2 mile f rom Route 48 near the Illinois Central Gulf Rai troad, and within the 60 dB contour of sirens 5 and 14. The sirens yielded excellent audibility, exceeding the 50 de base Line for 95 percent of the time. The signals peaked at 75 de, clearly unobscured by the 40 de ambient noise produced by birds, insects, and distant traffic. This region is obviously weLL blanketed by siren V acoustic coverage.
- Location SC-5, like SC-4, was approximately equidistant f rom sirens 5 and 14, within the 60 dB contour. The ambient noise of 60 d8 was produced by birds, wind, and traf fic. The siren SPL exceeded 70 dB for only.15 seconds, or 10 percent of the total activation time, l . indicating f air audibility. The siren sound level generally ranged between 60 and 70 de, as predicted by the ATI computer model. The fair audibility rating is simply a reflection of the high ambient noise level along Route 48, which is largely transient traffic.

. s Location SC-6 was monitored during the second activation of the St.
O V Charles Parish sirens. It was situated near a secondary road, a good j 1 distance from the Louisiana and Arkansas raitroad tracks, outside of ! the 60 'd8 contour of sirens '32 and 52. These sirens, in add.ition to. . siren 34, were clearly heard during the activation. The signals were recorded above 50 de for 34 percent of the time. This is considered good audibility since the background noise Level for this region is only 40 de. i l l Location SC-7 was just inside the 70 de contours of sirens 32 and 34, in a residential community off Route 48. Both sirens, especially 34, were heard clearly above the 50 dB background noise of birds, crickets, and distant passing cars. The siren SPL exceeded 60 de for l 84 seconds, or 47 percent of the time, providing good audibility and j close agreement with the level predicted by the ATI computer model. Since the residences near Location SC-7 are quite a distance from the sirens, they receive good acoustic coverage. Map 1 shows that the towns of New Sarpy and Destrehan are also weLL covered. *
- Location SC-8 was near a small warehouse by Route 48, just inside the 60 dB contour of siren 32. Sirens 32 and 30 were both Loudly heard with levels peaking at 80 d8. The high ambient noise, 60 d8 for this
- area, was produced by traf fic and industrial activity. The siren signal level exceeded the 70 dB baseline for 13 percent of the time, indicating fair audibility. These levels are higher than those O

predicted since SC-8 Lies weLL outside the 70 de contour. This reflects the conservative asstaptions used on the ATI computer model.
' Location SC-9 was in a flat grass, covered area at the western edge of the 70 dB contour of sirens 29 and 30. Many sources contributed to the 60 de background noise level, but the sirens were Loud and clear, peaking near 90 de and exceeding 70 de a full 91 percent of the time, providing excellent audibility. These anomalously high readings are partially due to the lack of any barrier attenuation (houses, trees, or hitts) at the monitoring location. This is a strong indication that the town of Norco receives good siren acoustic coverage.
The predominant sir 9ns for Location SC-10 were 25 and 28. The site was located near a power plant weLL within the 60 dB siren acoustic contour. The power plant, along with the wind, contributed most of the 50 dB background noise in the region. For 21 percent of the time, the siren SPL exceeded 60 dB, often reaching 65 dB in accordance with
- the computer model predictions, and also yielding i good audibility.
St. John the Baptist Parish Activations
- For the first total activation of the sirens in St. John the Baptist Parish, measurement Location SJ-1 was situated within the 70 dB contour of siren 2, some distance off of Route 44. Industrial noise consisted mostly of the 50 dB background ambient noise, along with t
. O Acoustic TECHNOLOGY INC.
some Route 44 traffic. The signal level exceeded 60 de 59 percent of p the time, providing excellent audibility'. Since sirens 2, 3, and 12 V ' were all clearly heard, more than adequate acoustic coverage for the ) 1 towns of Garyville and Lions can be assumed. Monitoring Location SJ-2 was near a large grain elevator about 100 yards. f rom Route 44. The 50 de background noise was produced by plant activity, Route 44 traffic, and birds. The siren SPL topped the 60 dB baseline for 53 seconds, or 32 percent. of the total
' activation time, yielding good audibility. Since SJ-2 was the edge of the 70 dB contour for sirens 3 and 4, the peak signal levels of around 70 dB were as expected. Both sirens were clearly heard and provide good coverage for the residence in the vicinity of the elevator.
! O Location SJ-3 was in a populated area near Route 44, approximately equidistant from sirens 4, 10, and 11. Birds, traffic, and rain were the major ambient noise sources, creating a background Level of 60 dB. The siren signals were clear, peaking slightly above the expected maximum of 70 de, and remaining above 70 de for 20 percent of the duration of the test. Audibility was rated as fair. Location SJ-4 was in flat, fielded area just north of Route 61. The predominant siren was 48 although sirens 4 and 49 were also audible during the activation. Background noise of 60 dB resulted from l 0 f ) Acoustic TECHNOLOGY
I birds, crickets, and Route 61 traffic. The siren SPL: remained above ( 70 de for 73 percent of the time indicating excellent audibility. The unusually high peak value of 90 de can be attribu't ed to the lack of attenuating structures or topographical . barriers in the vicinity. , These high levels conform with the predicted results since SJ-4 Lies weLL within the 70 de contour of siren 48. Location sJ-5 is located north of Route 44 in a residential area, within the 70 de contour of predominant siren 10. Traffic was the major source of the 60 dB background noise. The siren SPL exceeded 70 de during 19 percent of the activation, providing fair audibility. It is safe to assume,,that the surrounding residences receive adequate acoustic alert coverage, because of the. transient nature of most of the background noise which was traffic. ( - Location SJ-6, on the edge of the 60 dB contour between sirens 40, 8, and 50, was monitored during the second activation of the St. John
! the Baptist Parish sirens. SJ-6 Lies in an area with 50 dB ambient noise level. In spite of background sources such as cars, planes, and a lawnmower, the sirens were clearly heard, producing signals of i at least 60 dB for 74 percent of the activation, and, thus yielding i ! excellent audibility. The numerous residences between the measuring site and the three predominant sirens are clearly blanketed by the , necessary acoustic coverage.

Location SJ-7 was on the northern edge of the 60 dB contour for siren 50, near Interstate 10. The major highway traffic contributed to the 60 dB ambient noise Level. The measured siren levels exceeded 70 de for only 12 percent of the time. These signal levels were actually ~ higher than those predicted by the conservative ATI computer model since SJ-7 was weLL outside the contour of 70 dB coverage. Siren audibility would be significantly greater at distances further f rom I-10, where there would be less traffic noise. Lo' cation SJ-8 Lies in the town of Laplace between sirens 6, 39, and
- 15. ALL three sirens were audible, siren 39 being the clearest.
Background noise was from birds, crickets, Light traffic, and children playing, the level being 60 de. The measuring location was within the 70 dB computer generated contour, and the peak values of 78 dB corroborate this. The siren signal level exceeded 70 dB for 48 ' seconds, or 30 percent of the time, giving good audibility in the surrounding area. Location SJ-9 was near residences along Route 628. The site was within the 70 dB contour between sirens 15,17, and 22. The siren i level peaked around 75 dB for 18 percent of the time, providing fair audibi li ty. Sirens 15, 17, and 22 were clearly heard, and even siren 45, across the Mississippi River, could be heard. , O ' __j)) Acoustic TECHNOLOGY INC.
Location SJ-10 was in a residential area of Low ambient noise (40 dB) within the 70 de contour of sirens 17,19, and 51. Audibility was excellent. The siren SPL remained above the 50 de baseline for the f ull .165 seconds, 100 percent of the activation time. The flat. topography contributes to the strong siren signal propagation in this region. 4.3 EVALUATION OF TOTAL SIREN ACTIVATION The siren monitoring / testing proved that the total siren alert system provides excellent coverage throughout both parishes. Of the twenty siren monitoring locations, six were rated as having excellent siren audibility. Eight locations had good audibility, and six had fair audibility. At all locations, the siren signal was clearly audible for a portion of the activations. This analysis confirms ATI computer model predictions and ensures siren audibility for the proximities of all tested areas. O g3 Acoustic TECHNOLOGY INC
5.0 CONCLUSION
S CN U The alert / notification system for the Waterford-3 Steam Electric Station has been evaluated and verified through siren tes' ting, siren performance monitoring, and the testing of the helicopter airborne warning system. This verification and evaluation is documented in this Volume II and Volume I entitled, Analysis, Verification, and Testing of the Siren Prompt Notification System for Waterford-3 Steam Electric Station (March 1984). It is concluded that all populated areas within the 10-mile EPZ have been provided with adequate siren acoustic alert coverage and that all wetland and Lake areas are sufficiently covered by the helicopter airborne warning system. The primary alert notification sy' stem for the Waterford-3 Steam Electric Station is capable of notifying essentially 100 percent of the public within the 10-mile EPZ of the Waterford-3 Steam Electric Station.
