! II. WASHINGTON NUCLEAR PROJECTS 1, 2, AND 4 EMERGENCY PLANNING ZONE POPULATION _

The Washington Public Power Supply Systen leases 1089 acres of land on the Hanford Reservation, located north of Richland, Washington, and con-trolled by the Department of Energy. The reservation covers an area of approximately 570 square miles, consisting mostly of seni-arid land. The 0

9 land leased by the Supply System is approximately 3 miles west of the Columbia River and 12 miles north of the populated area of Richland.

o Population Estimates i Figure 1 is a map of the Ten-Mile Emergency Planning Zone.(1)

This Ten-Mile Emergency Planning Zone is the area for which the Early Warning Systen has been designed to cover.

Figure 2 present5 the compass sector population estimates for 1980.

Estimates were made relative to the center of the triangle formed by the three reactors. These figures were taken from the WNP-2 Envi-conmental Report (2) whare references and bases are given. Con-tacts with the County Auditor's Office and the Post Office confirmed the accuracy of the population data.

~

o Permanent Residents Permanent residents included all people residing in the area but L excludec cccupants of institutions. The ten-mile radius around the 1 site is shown in Figure 1. In 1980, an estimated 1306 people were livir.g within the Ten-Mile Emergency Planning Zone. The nearest inhabitants occupy farms which are located east of the Columbia River and are thinly spread over five compass sectors. There are no l permanent residents located within three miles of the site. Only about 80 persons reside betwean the three-mile and the five-mile radii; these are all located east of the Columbia River.

1 i '

l l

a .

Of the 1306 people residing in the 10-Mile EPZ, about 996 live in Franklin County and about 310 in Benton County. None of the resi-a dents live in incorporated cities.

i There are no significant changes in land use expected in Franklin County over the next several years and, as it is currently irrigated 9 to about the maximum amount practicable, little population increase is foreseen. No significant change in land use en the Hanford Reservation is expected, and no foreseeable population will reside there; however, the unincorporated area near the Horn Rapids Dam on

, the Yakima River in the SSW sector is expected to be the primary

, growth area within the 10-Mile EPZ. Population growth within this area is projected to be about six percent per annun.(3)

.; o Transient Populations The transient population is divided into three main subgroups:

1) industrial employees, 2) migratory agricultural workers, and

3) sportsmen. Figure 3 illustrates this population location graphically.

Industrial employees in the 10-Mile EPZ total 20,080 and are all located in Benton County. Over half of the industrial employees

~

work at WNP-1, 2, and 4. The size of this work force projected for June 1982 is 10,700; however, this workforce varies considerably j with time. As many as 12,000 workers were employed in June 1981 prior to the slowdown of construction at WNP-4. At fuel load,

, employment at WNP-2 will be approximately 1,000. At that time, WNP-1 with full construction and WNP-4 on slowdown status could have as many as 6650 employees, making a site employment total of 7650.

Typically, the night shift at the site has been about 20 percent of the total force; so even with 7650 employees, only 6120 (the 80 per-cent on day shift) would have to be evacuated at any one time.

Therefore, it appears that the 10,700 planning figure is conservative.

Supply System, Downtown Complex 1021 Others in Port of Benton Industrial Complex 448 TOTAL 20,080 The majority of these employees work days, but there are some shift workers. Therefore, the planning figure of 20,080 to be evacuated is conservative.

s There are up to approximately 1000 migratory f arm workers in the Ten-Mile Emergency Planning Zone. The peak secson for these workers is May and June; the next highest employnent season is during the f all harvest. These workers consist of both permanent and temporary residents of the Tri-Cities area, some living within the Ten-Mile Emergency Planning Zone. The numbers shown on Figure 3 reflect their work locations in Franklin County within the Ten-Mile Emer-gency Planning Zone, not their residences.

Sportsmen, consisting of hunters, fishermen, and boaters, enjoy activities mainly along the east bank of the Columbia River. The primary fishing season is from June through November; the main hunt-ing season being October through January. The heaviest use of the area by sportsmen is on weekends and holidays in the early morning hours. On the average, 50 fishermen and 10 hunters are present in Franklin County during the weekdays. This increases to about 100 fishermen and 50 hunters on weekends and holidays. Sportsmen l also use the Yakima River, with an estimated maximum of 50 at any l time in this area. During peak fishing or hunting times, up to.

1050 sportsmen may be located within the Ten-Mile Emergency Planning l

Zone.

~J l

I The main concentration of sportsmen consists of fishermen located

~

just south of the Ringold Fish Hatchery spillway on the Franklin

County side of the Columbia River. Hunting consists of both water-fowl (hunted at the Wahluke Hunting Area on the Franklin County side of the Columbia River) and upland game birds (hunted inland on the farmlandofFranklinCounty).

O o Special Population There are no individuals within the Ten-Mile Emergency Planning Zone 7 confined to institutions such as hospitals, nursing homes, or penal

! institutions. There is one school, the Edwin Markham Elementary School, with an enrollment of 250 students. Although most of these students live within the Ten-Mile Emergency Planning Zone, the total

^

amount was added to the population for this study.

O III. CRITERIA FOR ACCEPTANCE 3 The Nuclear Regulatory Commission / Federal Emergency Management Agency

< criteria for prompt public notification are set forth in Appendix 3 of NUREG-0654/ FEMA-REP-1 and is summarized below.(4) 9 1. The minimtsn acceptable design objectives for coverage by the notifi-cation systems are:

o Capability for providing both an alert signal and an infor-

. mational or instructional message to the population on an area-wide basis throughout the Ten-Mile Emergency Planning Zone within 15 minutes.

o The initial notification system will ensure direct coverage of essentially 100 percent of the population within five miles of the site.

o Special arrangements will be made to ensure 130 percent cover-age within 45 minutes of the population within the entire plume exposure Emergency Planning Zone who may not have received the initial notification.

2. Th'e basis for exception must be doctsnented (e.g., for extended water areas with transient boats or remote hiking trails).

[2 3. A prompt notification scheme shall include the capability of local and state agencies to provide information promptly over radio and television.

4. The basic criterion needed for the design of a siren system is the acceptable dissonant sound level. As an acceptable criterion at l

most locations, 10 db above average daytime ambient background noise l

is suggested as a target level for the design of an adequate siren i system.

l

6

O t

5. Siren systems should be designed considering the demography and

~

topography of an area and taking into account other warning systems a in place or planned.

6. The maximum sound levels received by any member of the public should be lower than 123 db, the level which may cause discomfort to 9 individuals.

7. NUREG-0654 references alternate means of notifying the public and suggests that achieving a goal of 100 percent notification might be 7 accomplished by a combination of these inethods.

. P. For organizations proposing systems without field surveys, 50 db(a) is a conservative estimate of thi average daytime ambient noise level in areas with population densities of below 2000 persons per square mile. For organizations proposing systens without field surveys and population densities below 2000 persons per square mile, the siren system must be designed to produce a minimum of 60 db(c).

An attenuation factor of 10 db loss-per-distance doubled should be used to determine siien range in the absence of special geographical features. Those organizations applying the criteria should document the basis for their selection of appropriate values to include:

o Population densities, location of major transportation routes, and heavy industry a

o Attenuation factors with distance o Siren output db(c) at 100 feet vs. asstaned range and accoustic frequencyspect(a) o Maps showing siren location, size of coverage, and any features

, that could affect siren performance (e.g., hills) o Mounting heights of sirens l

7

^

ia i

, o Special weather conditions, such as expected heavy snow, which

^

might modify the design assumptions C) ,

9. The siren signal shall be a three to five minute steady signal I

capable of repetitions.  !

l

') 10. Types of tests and suggested frequencies are:

o Silent Test - Every two weeks ici o Growl Test - Quarterly and when preventive maintenance is

! performed l

o Complete Cycle Test - At least annually and as required for O formal exercises

11. The Emergency Broadcast System will be utilized to furnish real time canmunications to the public. The following steps to activate the Emergency Broadcast System will be taken:

o Broadcast emergency programming which may include recording the emergency message for later use.

o Broadcast an initial statement.

o Transmit the two-tone attention signal.

c l

o Broadcast the energency announcenent.

IV. EARLY WARNING NOTIFICATION PROCESS 1 .

!) The approach taken by the Supply Systein in designing the Early Warning

! Systen for the Washington Public Power Supply System's Nuclear Proj-

) ects 1, 2, and 4 is based on NRC-FEMA criteria as described in l:

Section III.

,o 1 The emergency shall be classified by the Plant Emergency Director as soon as an off-normal event occurs that corresponds to one of the initiating conditions. Each class is defined in such a manner so that emergencies l; can be classified either up or down, depending on whether the emergency

] becomes more or less severe. When there is doubt as to the classifi-  ;

cation of the emergency, the more conservative class shall be used.  ;

After classifying the emergency, the Plant Emergency Director will initi-ate notification of emergency personnel. The extent of the notification will depend upon the emergency classification.

Initial emergency notification to nearby Supply Systen plants, the State, County, and the Department of Energy will be made through the Security Communications Control Center. Both phone lines and radio consnunications are available. The nearby facilities will implement the necessary ener-gency actions. In the event of an emergency requiring protective mea-sures to be taken at the nearby facilities, the Recovery Manager at the Emergency Operations Facility will give specific instructions.

Notification of the County Emergency Dispatch Center and Benton County Emergency Operations Center in Kennewick, Department of Energy, and the Washington State Department of Emergency Services (State Emergency Opera-tions Center) will be by dedicated phone lines. Notification to the Nuclear Regulatory Commission in Bethesda, Maryland, will be made via the NRC dedicated phone network from the Control Room. The Nuclear Regula-tory Consnission offices in Bethesda will patch the call through to the Nuclear Regulatory Consnission offices in Region V, Walnut Creek, California. Notification of all other offsite emergency agencies will be made by telephone. Radio provides backup communications to the County Emergency Dispatch Center and Department of Energy-RL.

3 g

Activation of the Early Warning systen and emergency notification to both transients and residents is the responsibility of the Benton/ Franklin Counties Department of Emergency Services Director. Notification will be based on infonnation received from the Supp1'y System and in consultation with the staffs of the Benton County Emergency Operations Cerfter and Washington State Emergency Operation Center.

The Early Warning System is designed to provide both an alert signal and information to the population on an area-wide basis throughout the Ten-Mile (mergency Planning Zone within 15 minutes of a decision to activate the system. Two means have been established by the Supply System for notification of the public. Sirens are located along the Coltsnbia and Yakima Rivers in the Ten-Mile Emergency Planning Zone and at the plants to notify the transient and construction population. Coverage of the siren system is shown in Figure 4.

For residents within the 10-Mile Emergency Planning Zone, the tone-activated radios provide the primary means of notification. These radios ,

are activated by the Emergency Broadcast System and provide instructions for protective actions.

Areas not covered by the Early Warning System are:

o Uninhabited areas.

o Certain highways and roads where the only expected transient popu-lation will be persons in vehicles. These individuals would travel outside the Emergency Planning Zone within the 15-minute time frame.

o Persons in the shower or outside of their residences, outside of the hearing range of the sirens or the tone-activated radios.

However, it is likely that people not initially alerted by the siren signals or the tone-activated radios will eventually be alcrted by TV, radios (not of the tone-activated type), and other informal means, 10

including telephone calls from neighbors, friends, relatives, and word-of-mouth. In addition, the initial activation of the Early Warning ^

System would be followed by subsequent activations to ensure that the total population was alerted.

V. SIRENS To support ths design of the siren portion of the Early Warning System, daytime abient noise level measurements were made at various locations within the Ten-Mile Emergency Planning Zone in order to ensure that the daytime average abient noise level was within the 50 db(a) limit (refer to Table 1 and Figure 5). Note that the readings in excess of the 50 db(a) requirement were in very small localized areas. In addition to the abient sound level readings, siren sound coverage characteristics were tested within the Ten-Mile Emergency Planning Zone along the Colum-bia River. A single siren was positioned at the old Hanford townsite, one of the siren locations. Six monitoring points were located at vari-ous distances and directions from the siren (refer to Table 2 and Figure 6). The test siren was positioned on top of the old pumphouse approximately 25 feet above the ground, 120 feet from the riverbank, and 60 feet above the water level. The siren used for the test data was the Raytec Corporation electronic,122 db(c) at 100 feet, rotating type. Six monitoring points recorded abient sound levels during the 10-minute period prior to the siren test. Sound levels were monitored on'ce a minute for 15 minutes. High, low, and average sound levels were recorded using weighting scale a or b. Unlike the 122 db(c) omnidirectional siren progr amed for our Early Warning System, the tested siren rotated at three revolutions per minute; thus, monitoring points received six siren sound level peaks during the test. High, low, and average sound levels were recorded using weighting scale c. The primary purpose of the test was to determine the sound attenuation factor for sound propagation up and down the Coltabia River (refer to Table 3). The formula used to calculate the attenuation factor is:

The following commonly used sound propagation formula is used to deter-mine the range from the source of sound when the attenuation factor is known.

Ro = Range in feet where sound pressure level is known Lo = Known sound pressure level in db d = Attenuation factor Solving for the attenuation f actor, s

1g2 d = (L -L (Equation 2) log ([o)

Then the field measurements of Lx and Rx were inserted into the above equation and an average value for the attenuaticn factor was calculated

~

where the transmitted db (L,) was set at 122 db and the distance refer-ence (Ro) was set at 100 feet. The average attenuation factor was 8.83 db with the worst case being 9.6 db.

Worst Case 9.6 8,793 Average 8.83 12,992 The present Supply System siren design calls for a receive range of 9240 feet for the 60 db(c) level. This is within five percen+. of the worst case and the distance achieved for the average attenuation factor

., of 8.83. This design criterien meets the intent of the NUREG-0654, Rev.1, criterion to provide an acceptable dissonant sound level for areas with population densities below 2000 persons /mi2 ,

The proposed locations of the sirens were determined based on'the following:

o Estimate of siren coverage to 10 db(a) dissonance level, with a 60 db(c) minimisn coverage level o Availability of power o Site access o Topography o Wind direction and speed i

The selected areas within the Ten-Mile Emergency Planing Zone provide notification to sportsmen, boaters, and other transients along the entire length of the Coltsnbia and Yakirha Rivers within the Ten-Mile Emergency l Planning Zone, populated areas in Franklin County (out to five miles of the plant), Bonneville Power Adninistration Substation, Department of L Energy 300 Area, and the Supply System Main Headquarters Complex.

l 14

o Siren Systen and Design g The siren systen consists of 14 pole-mounted,122 db, electronic, onmidirectional sirens consisting of 12 horns operated by a 24-volt, direct-current, internally mounted battery. All electronics, power, and control equipment is housed in a steel, weatherproof, pole-o mounted cabinet. The sirens are mounted on 50-foot, Class II, cedar polesdesignedtowithstandinexcessof100mphwinds(referto Figures 7 and 8). Where needed, the poles will be mounted in con-crete. All siren locations on the Hanford Reservation will be c' fenced; the remainder of siren location boundaries will be estab-lished per land-owner requests. The area around each pole for approximately 15 feet will have gravel-covered plastic for fire protection. Each siren will have an appropriate warning sign c stating that its sound can be dangerous to health.

There are two types of power supply utilized. The seven sirens located in Franklin and Benton Counties are operated by a 110-volt, alternating-current (A.C.), battery charger. The battery' capacity, when fully charged, is capable of one 30-minute blast or ten 3-minute blasts.(5) The units utilizing the A.C. charging are capable of fully recharging the battery daily. In the event of a power failure, the battery capacity is such that it will lose nine ,

minutes of siren output per day.

The remaining seven sirens located on the Hanford Reservation are solar powered, battery charging. The battery capacity remains the same as the A.C. units; however, the recharging system allows the siren to be blown for not more than ten 3-minute blasts in any five-day period. The design criteria for the solar cells takes into consideration the worst-case winter months.

All of the sirens' batteries are capable of being externally charged via a vehicle-mounted charging unit. Therefore, all systems will be operational during extended p]wer outages or solar blackouts.

~

15

O o System Control

, The siren control system is a Remote Data Acquisition / Control System that will be used for transmitting alarm or status messages between the master station and remote stations. The system uses UHF radio as the communications link. The Data Acquisition / Control System

, consists of a master station and remote status and control units as follows:

- 1 remote station at each siren, D.C. powered (14 total) 1 remote-control initiation station ,

1 master station (for status maintenance)

Each siren will have a status and control unit capable of two-way consnunications with the master station and will be capable of reporting up to four input conductions (status points) plus a test indication. The unit will report all of its informatien upon recep-tion of an interrogation message from the master station. Each status and control unit will have a unique address that can be user changeable. Areas monitored are:

- Tampering Battery capacity

- A.C. power

- Siren output The control section will be equipped with a minimt:n of four control relays. The relays will be momentary-contact closure (one-second closure). One comand function will operate one relay. The control l

section will respond to commands directly addressed to it. It will also respond to commands addressed to all remote units.

Power supply for each of the status and control units (including radio) is ft c1. a 0.C. power supply of 12 VDC + 2 volts.

16

O l

The master station located in the Supply System's plant support facility will provide the following functions:

^

1 g

i - Operatcr's interface via a control panel Message reception l - Message transmission

]O -

Data display and hard copy printout l 1 The operator control panel will enable the operator to perfom main-  ;

tenance checks on the system to ensure the sirens are operating  !

O properly.

The remote control initiation comand station will be used to Octi-vate the sirens and is located in the Emergency Dispatch Center 3 (911), basement of the Kennewick City Hall, Kennewick, Washington..

All swit,ches and indicator lights will be individually color coded; all switches and indicator iights will be spring loaded with an A.C.

power indicator light provided on the front of the unit.

O Activation is by a two-state frequency, shif t-keying modulation system. The keying modulation system is used to transmit binary-coded alarm and control information over the communications O channel. Each message begins with a pretone used to break squelch in the receiver. Next comes a preambla consisting of th'e last eight bits of the data word; the preamble is used for clocking and syn-chronizing the receiver. Finally, each data word is transmitted twice for a double scan.

Both the Master Station and Remote Control Initiation Station are on uninterrupted power supply.

17

T VI. TONE-ACTIVATED RADIOS

- Tne Early Warning System is specifically intended to meet the needs for the alerting and notifying of persons living in the Ten-Mile Emergency Planning Zone. The siren system is one portion of the comprehensive plan established to effe'ctively notify the populace. The second portion of the comprehensive approach is supplying households in the Ten-Mile Emer-gency Planning Zone with a tone-activated radios. This system uses an attention signal consisting of two precise audio tones transmitted simultaneously.

Each major broadcast station in the county is required to have an Emer-gency Broadcast System (EBS) encoder and receiver / decoder installed.

Certain stations are designated as Comon Program Control Stations and take the responsibility of getting all other stations in their area alerted and ready to rebroadcast the energency messages. The Comon Program Control Station in this area is Tri-Cities Consnunications, Inc.

(KONA,AM-610,FM-105.3). As of January 1982, KONA will provide 24-hour broadcasting. Emergency notification to KONA is the responsibility of the Benton/ Franklin Counties Department of Emergency Services Director.

The tone-activated radios are capable of decoding the standard Emergency Broadcast System two-tone attention signal. Upon receipt of the Emer-gency Broadcast System tone, the decoder shall enit an audible alert tone for a minimum of five seconds, along with activating an indicator light.

The indicator light remains on until manually reset. The audio output is user adjustable; however, the minimum audio output is preset. The receiver sensitivity is a minimtsn of 30 microvolts for 20 db 5/N, selec-tivity is 25 db; at 9 KHz, frequency stability is .25 percent, -10 to +50C, and htans and noise are 50 db at one micro volt input. The power supply is AC/DC. The unit will operate on a built-in rechargeable bat-tery with a six-hour minimtsn duty cycle in the unmuted condition. The battery charger shall operate on 115-volt, 60 Hz, A.C. power. It is also capable of operating the radio without batteries. The charger will com-pletely recharge the dead batteries in 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> with the radio in the on 18

. furnished, with all controls easily accessible from the top or front.

, Mean time before f ailure of the unit is a minimisn 50,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />.

J When the receivers are not used for receiving emergency information, they

, may be used to receive the normal KONA programing. Receivers used in a this way provide items of considerable day-to-day value to residents, being, in effect, a free radio with one channel of program material.

When the programmed material can be received at any time, the resident is also reassured that his receiver is in good working order. The need for

! O frequent testing is thereby eliminated, minimizing annoyance and anxiety to residents.

Distribution of the tone-activated radios are to be conducted through a coordinated effort between the Benton and Franklin County Department of Emergency Services and the Supply Systen. Members from these groups will contact each household within the Ten-Mile Emergency Planning Zone and explain the features of the radios.

In order to maintain a thorough and complete coverage of the area, vari-aus approaches will be used by the Supply System and the Benton County Department of Emergency Services to keep up-to-date records of persons moving into the Ten-Mile Emergency Planning Zone. These are:

o Public utility Districts o Post Office route carriers o County Auditors ,

o Recanvassing of the area The primary method will be through the Public Utility Districts and the Post Offices. The alternate approach will be through the County Audi-tor's Office or, if need be, recanvassing the area.

19

1 7

i VII. SYSTEM MAINTENANCE i

i 3 The Supply System will be responsibile for maintaining the tone-activated i radios; however, each resident supplied with one of the tone-activated radios has the responsibility to inform the Supply System of the radio malfunctioning. A representative of the Supply System will then contact

,c) the individual to repair or replace the radio, as needed.

1 To ensure a high degree of reliability from the siren system, a program

" of inspection, adjustment, lubrication, testing, and repair will be

developed by considering the maintenance recommendations of the siren manufacturer, along with other considerations such as weather and spe-cific siren locations. A full and complete program will be in place when the siren system is completed.

3 f

20

j VIII. SYSTEM TESTING ,

q jg It is impossible to accurately predict, on the basis of theoretical cal-j culations, whether the required public notification will be achieved.

Therefore, a testing progra will be required as part of the systen

{

installation and operation to determine the adequacy of the system cover-

)9 age. The preoperational testing progra will include functional tests

! for the individual sirens and their radio controls and the tone-activated I

radios. At least one full-scale test of the systen will be performed j before the system is declared operational. Followina this test, a FEMA jg approved evaluation will be conducted to determine the effectiveness of j the systen. In addition to the testing, Benton and Franklin counties, in i conjunction with the Supply System, will initiate a public education I program to inform the public of the existence and purpose of the Early

~

Warning System. -

As described in Appendix 3, Section H, NUREG-0654, Rev.1, " Siren Tes't'ng Guidance," three tests of the siren system are required:

o Silent Test - Weekly' o Growl Test - Quarterly o Complete Systen Test - Annually

. Testing of the tone-activated radio system is done by the local EBS sta-l tion on a weekly basis. Instructions will be provided with each radio distributed to notify the Supply System of any malfunction of the radio.

21

.o IX. SCHEDULE OF INSTALLATION jg An installation schedule has been established to ensure that the Early Warning System is functioning prior to the fuel load exercise.

I j The following is a breakdown of the steps necessary to complete the
