.;}
w The format of this system description follows the items and issues of Appendix 3 to NUREG-0654, Rev. 1.
There are special considerations in the design of this system which include:
1) 50% of any circle about the plant encompasses parts of Lake Michigan; 2) two separate counties, Kewaunee and Manitowoc, are within the plume exposure Emergency Planning Zone (EPZ); and 3) two separate
- 3 g
power flacilities operated by different licensees are within a common EPZ.
w To facilitate notification system planning, a common EPZ has 'been defined.
j This EPZ "is th'e total area covered by two 10-mile radius circles centered on the Point Bea(5 Nuclear Plant (PBNP) and the Kewaunee Nuclear Power Plant (KNPP).
The entire EPZ is within the State of Wisconsin.

Concept of Operations
}y'

The Public Warning / Notification System is an extension of existing sirens

' h k'bY the'determf nation at PBNP of a need for a protective recommendation e
3 to the population, a formal recommendation for system activation will be
.c
""g issued to the State of Wisconsin's Division of Emergency Government (DEG)
V utilizing either the National Warning System (NAWAS) or commercial tele-
,, libone.
Following confirmation of the recommendation, the State DEG must l

- ?-
direct tre,resriective county, Manitowoc or Kewaunee, to activate selected 7
or all, sirens. -Concurrent with the siren activation, the DEG will initiate i
a notif.icM19n message on the EBS.
NAWAS ties together KNPP, PBh ', Manitowoc and Kewaunee County Sheriff's dispatchers, Wisconsin Warning Center One s
,,d / Madison), and nultiple State backups located in Madison and Fond du Lac.

Criteria _fgr Acceptance h
@l. 'pubhc alerting within the EPZ will be accomplished by an acoustic 2(
alerting signal.
The notification will be via commercial media as c
tie.d~into the_ EBS.
A tabulation of radio and television stations
+.
V' se'rvirg-tkEPZ has been provided to the permanent residents of the j f,'EPZ.
Mul tiple media outlets are preferable due to the typical
\\
f >N ' 3 characteristics of the area stations:
e.g., daytime, short range, diverse' demographic coverage.
The National Oceanographic and Atmospheric.ftdministration (NOAA) signal in the southern portion of i
p the EPZ,is;too weak to provide reliable notification.
s
' 5.^
a)
The radio and television stations serving the EPZ cover an area which, in total, exceeds the notification requirements for the EPZ.
Utilization of the EBS ensures that informational or instruc,tional messages to the population will be provided

.~
within 15 minutes of initiation.
Within five miles of either plant, 100% of the area is served by sirens as the primary alerting device and 90% of the population within the total EPZ may be alerted by sirens.
For the less populated five to ten mile sectors, mobile " yelp" or police sirens will serve as the
. alerting device as addressed in Section 3 -of Appendix 3 of NUREG-0654.
b)
The system, as shown in Figure 1, provides _100% geographical coverage of the land isrea within five miles of the plant.
c)
Total coverage within the full EPZ will be provided by either supplemental sirens as noted in Figure 1 or by mobile systems.
This mobile notification procedure has been exercised.
Alerting of individuals on Lake Michigan must ccme from arrangements with the U.
S. Coast Guard station, either as a result of advance arrangements with PBNP or as an agent of Federal Emergency Management Agency (FEMA).
The State of Wisconsin Department of Natural Resources has a plan for notifying personnel in the Point Beach State Forest by using park vehicles with loud speakers.
3.
The coordinated authorization or direction by the State DEG duty officer or acting director to the county dispatcher to activate the alerting system and dissemination of notification material on the EBS assures timely netification and ensures a uniformity of response between the two separate counties.
Informational material for the affected segment of the population will be provided consistent with the recommendation to activate the system.
Utilization of the EBS is discussed in a combined FEMA, Federal Communications Commission, and NOAA pamphlet (L-93): "In the last several years, the original concept of the EBS has been expanded so that it can also be used during day-to-day emergencies at - the State and local levels to provide the means for prompt,. reliable receipt and release of life-and property-saving warning as well as emergency information.
Examples of day-to-day emergencies are:
tornadoes, and nuclear accidents involving hazardous materials and toxic gases, and civil disorders."
C.
Physical Implementation 1.
The stations from which decision making personnel will function are staffed 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day.
b)
These stations are the plant, the county dispatcher offices, and the state warning centers.
They are all linked by NAWAS and commercial telephone as a minimum.
The State maintains alternate warning centers.
c-f)
These items are all addressed within the design of the NAWAS.
The U.
S.
Nuclear Regulatory Commission (NRC) and FEMA have endorsed the use of NAWAS by licenseees and a unique system description herein is unnecestary.
HAWAS has been in use and is tested at frequent intervals.
g)
All sirens have two-tone capability:
an alert signal (constant tone) and 2 attack warning (waverirg tone).
In cddition, most sirens wi'.hin the system have the capability to provide a third or loco use tone (interrupted constant level tone).
This tone is not being implemented at this time but remains a future option with the respective county.
The third tone will not comp % mise the siren's primary purpose.
- 2. a-c)
Integration of the warning system with NAW/ 5 and existing warning centers meets the criteria for responsibility assign-ment, dissemination time, and notification capability.
d)
The decision to respond to the recommendation formulated by the plant or any other party external to the State rests with the State DEG.
This assignment takes into account the non-emergency nature ^ of some organizations and the routine posture of key staff elements.
- 3. a-e)
The fixed alerting portion of the system (sirens) is designed to provide a sound signal of constant tone to essentially 100%
of-the population within five miles of either plant and 90% or greater of the population within the combined five mile zones of PBNP and KNPP.
Sirens will also be located in Two Rivers, Mishicot, Kewaunee, and southwest of Kewaunee (an area of housing growth).
The sirens in rural settings have been located using sound levels of 60 dB(C) to describe their range.
Final siting adjustments were made to account for demography and topography of the area.
Table 1 is a tabulation of sirens C ch supplements Figure 1.
An attenuation factor of 10db loss per distance doubled was used to determine siren ranges.
g)
Wisconsin Public Service Corporation. Wisconsin Electric Power Company, and Manitowoc and Kewaunee counties have been in close cooperation in the siting and incorporation of the warning systems into the emergency preparedness program.
The State of Wisconsin DEG has been involved in augmenting the system for meeting the notification objective with EBS.
h)
The anticipated testing will be a monthly test where the system develops full output for a few seconds.
This testing is in accordance with FEMA guidelines and is consistent with current county practices.
4.
The message dissemination portion of the system is already in place.
The general public will be instructed via the media and a specific mailed public education program that the proper response to an alerting siren signa; is to turn on the radio or television to a local station.
This public education program will explain the use of this system for natural as well as man-made emergencies.
The Emergency Broadcast System is designed to handle messages of this type.
To expedite and_ assure message accuracy, the State Division of Emergency Government will initiate the message dissemination.
The initiation of he message to the EBS will take place through the Common Program Control Station (CPCS) in Green Bay. -This initiation can be carried out via the switched telephone network, the originating -
Primary Relay Station in Madison or point-to point radio to 'the
- Brown County Sheriff. Department in Green Bay.. The CPCS will then disseminate the message.throughout the East Central Area consistent with established EBS practices. ~All commerical radio and television stations in the east central area are members of the EBS. The EBS is in place and exercised regularly..The alerting system will be in place in early 1982.
