SYSTEM DESCRIPTION PUBLIC NOTIFICATION SYSTEM CATAWBA NUCLEAR STATION 1.0 SCOPE The public notification system as required by 10CFR50 and NUREG-0654, Appendix 3 will be implemented using fixed sirens in the Emergency Planning Zone around the Catawba Nuclear Stc; ion.
Large area warning systems are most economical and effective where the action necessary, once the siren is sounded, is simple and understood by the public.
The public will be made aware of the purpose of the siren sounding which is netice to listen to the Emergency Broadcast System (EBS) radio or television station for specific information and instructions concerning the situation at the Catawba Nuclear Station.
The Common Program Control Station (CPCS-1) is designated as WEZC-FM located in Charlotte, N. C.
The sirens will be sounded in the " ALERT" (Civil Defense) signal mode which is a three (3) minute steady signal.

1 3.0 DESIGN CRITERIA System design criteria is as follows:
3.1 Within fifteen (15) minutes of the State / County determination that public protective actions are necessary, provide Alert (sirens) and Notification (EBS) to the population within the Catawba Nuclear Station Emergency Planning Zone.
3.2 Provide a siren system with an acceptable dissonant sound level 10 dB above average daytime ambient background noise of 50 dB(a) for areas with a population below 2000 persons per square mile, and 10 dB above average daytime ambient background noise of 60 dB(a) for areas above 2000 persons per square mile.
(Density to be determined in 1 mila radial, 22 sectors.)
3.3 Locate sirens considering the demography, topography, and heavy industry within the area.
3.4 Limit siren sound level received by an person to less than 123 dB(c).
3.5 Limit siren sizes /models to 125 dB and 113 dB (dB(c) at 100 feet) to minimize the number of different models which simplifies the task of long-term support.
3.6 Use a conservative sound propagation loss factor of 10 dB per distance doubled to compute siren coverage.
This results in the 125 dB model providing a 9050' radius coverage and the 113 dB model providing a 3950' radius coverage per Table 3.1 (Range calculated per the formula shown in Figure 3.1).
3.7 Radio-controlled tone activation from each county for those sirens within their boundaries.
3.8 Existing alerting equipment, such as Volunteer Fire Department sirens, will not be utilized in this primary system.
3.9 Provide adequate all-weather maintenance access.
3.10 Paint equipment to provide blending with the surroundings to minimize the prominence of the siren installation.
3.11 All equipment will be designed for a forty (40) year life in an outdoor environment with normal maintenance and parts replacement.
3.12 The siren equipment shall be capable of producing both the Civil Defense
" Alert" (steady) signal and " Attack" (wavering) signal.
The counties may actuate either of these two (2) signals with the proper encoder code selection.
3.13 The siren equipment will be designed to provide continuous duty (sized for continuous repetitive three (3) minute cycles).

4.0 SYSTEM DESCRIPTION The Emergency Planning Zone (EPZ) around the Cattwba Nuclear Station includes areas in York Costy, South Carolina and Mecklenburg County, and Gaston County, North Caroline.
The siren system network to provide a minimum of 60 dB(c) area coverage will consist of sixty-four (64) fixed siren locations as shown on Figure 4.1.
Sixty-three (63) of this total will be of the 125 dB(c) siren rating each cover-ing a 9050 feet radius area and the remaining one (1) will be 113 dB(c) rated covering a 3950 feet radius area.
Table 4.1 lists additional siren siting information.
The sirens will be radio-controlled, tone actuated, for each of the counties for those sirens located within their boundaries.
The counties will be provided with a tone encoder to be connected to an existing radio transmitter to be designated by county officials.
York County will control forty-nine (49) sirens, Mecklenburg County will control ten (10) sirens, and Gaston County will control five (5) sirens.
The sirens will be located along existing highways and roads that traverse the Emergency Planning Zone.
The major transportation routes for the 0-10 mile radius area are shown in Figure 4.2.
The siren installation will consist of the siren components (model dependent),
a radio receiver / tone decoder, radio antenna, motor starter control box, and miscellaneous electrical service components.
The mounting height of the siren horn assembly will be a minimum of fifty (50) feet above the ground with all siren and support components mounted on a wood pole.
Equipment from the pole top to the ground will be painted brown and the equip-ment above the pole top will be painted gray.
The proposed siren system provides reasonable assurance that coverage approach-ing the design objectives will be achieved.
However, there are limitations in employing an outdoor warning system with the expectation of achieving 100 percent notification to the public.
This is because of the many variables including weather conditions, tree foliage, local topography, and competing noise sources inside and outside dwellings.
The majority of the people not alerted by the siren sound due to other noise sources or sound attenuation variables may well be watching TV or listening to radio.
In that case the special emergency announcements made on the EBS radio and TV stations would l
attract their attention.
Even with a higher level siren signal, there is a possibility that the system could not assure alerting everyone who is indoors in a high ambient noise area.

5.0 AREA POPULATION DISTRIBUTION Several communities are located in the Emergency Planning Zone around the Catawba Nuclear Station.
The larger communities include River Hills Plantation (approximately four (4) miles north), Tega Cay (r.pproximately two (2) miles southeast), Lakewood (approximately three (3) miles south), and Newport (approximately five (5) miles southwest).
Note Table 5.1 from the Final Safety Analysis Report for Catawba projecting 11,859 people in 1981 in the 0-5 mile radius area of 78.5 square miles.
This yields approximately 150 persons par square mile which is well below the " rural" classification of 2000 or less people per square mile.
In the 5-10 mile area of the EPZ are the cities of Rock Hill, York, Clover, Pineville, and Fort Mill.
For alerting purposes, each of the city limit areas are considered above 2000 persons per square mile although portions of Rock Hill are the only areas above that figure at this time.

6.0 POWER DISTRIBUTION AND RELIABILITY The electrical power distribution for the siren system is very reliable as shown on Figure 6.1.
The power is derived from more than five (5) power t
stations in the EPZ vicinity and flows in from at least five (5) directions.
In addition to this redundancy, the more than six (6) substations within the area are interconnected.
The loss of an individual substation or power source would not result in a total siren system failure.

7.0 SYSTEM CONTROL The siren system will be radio-controlled from each county using an existing county selected radio frequency.
A tone encoder will be installed in the county communications center which provides specific tones and timing sequences to be sent to the transmitter.
The tone encoder requires a key to enable its functions.
These siren sites within the county boundaries will actuate in the selected mode as the tones are received and decoded at each site.
Radio control tone commands include three separate codes which are " Alert", " Attack",
and " Cancel".
The " Alert" code activation will produce a three (3) minute steady signal or shorter if the " Cancel" code is sent.
Only the " Alert" and
" Cancel" commands are used for the Catawba EPZ procedures.
The county may elect to use the " Attack" mode for other purposes.
Local manual controls are provided at each siren site within locked enclosures for maintenance and checkout purposes.
County emergency preparedness authorities having system activation responsibility are as follows:
York County Mr. James L. Carroll, Director, York County Emergency Management located in York, S. C.
Mecklenburg County Mr. Kenneth Williams, Director, Civil Preparedness located in Charlotte, N. C.
Gaston County Mr. Robert Phillips, Director, Gaston County Emergency Management Agency, Gastonia, N. C.

8.0 SYSTEM TESTING AND MAINTENANCE The tests listed per Table 8.1 will be routinely performed on the indicated schedule to insure siren system reliability and operational readiness.
The Silent test will be conducted by the county control center personnel.
The quarterly Growl test will normally be performed by Duke Power Company personnel locally at each siren site.
County personnel will also be required if the Growl test is conducted remotely from the control center. Additionally, during this test, normally conducted locally at the siren site, the mechanical counter recording the number of silent tests will be confirmed.
The annual full cycle test will be conducted during the formal preparedness exercise and will be a cooperative effort of all involved.
Preventive and corrective maintenance for the siren system will be provided by Duke Power Company personnel.
Optionally, the tone encoders at the county control centers may be maintained as part of the transmitter equipment by county contracted personnel.
