NOTE: Chlorination t rains s! ould be lef t in service, if possibic, to evacuate the system.
CA11T10N White vapors given off from the reaction of ammonia and chlorine are highly toxic. Additionally, ammonia in the liquid form is hip,hly corrosive. Do not allow liquid to be squeezed out when searching for leaks.
(6) H the source of the leakage is unknown, TilEN CONDUCT a search of piping, valves, and components, by puf fing ammonia fumes from a squeeze bottle or by use of a swab soaked with ammonia.
(7) H the source of the leakage can not be determined.
TilEN IS0! ATE chlorine tank car as soon as posulbic, leaving the Chlorination System in service to evacuate system.
(8) b'lllit) the source of the leakage is determined, TilEN PERFORM the following:
(a) H on an individual train, THEN CLOSE the inlet valve to the evaporator for that specific train.
(h) H the leakage is too exceustvo or cannot be isolated by an individual t rain, Ill!!;t.{ CLOSE the tank car outlet valve, 2 CS-U-V10013.

l (3) Q1f Site Emerr.encies JJ' the chlorine emergency is off sito, TilFN PROCEED as follows:
l F_gIE: Hilitary Ocean Terrninal Sunny Point personnel should evacuate all personnel to a safe area f rom the scene of any chlorine leak.
(a) NOTIFY the Shift incident Comrnander MD, if requested, ACTIVATE off shift personnel group call number in accordance with Attachment 2.
(b) REFER to Attachment I to determine the isopleth of cloud formation.
4.0 CENERAL On Site Emergencies: Due to the nature of chlorine gas, low lying areas should be avoided._ Chlorine gas is approximately 2h times heavier than air, therefore, likely areas of high concentration would be:
- Circulating Water intake Structure
- Service Water Building (specifically lower levels) e Augmented Off Gas Butiding
- Diesel Generator Building 1.ower 1,cVel
- Diesel Cencrator fuel oil stcrage tank area (4 day tank room) e Radwante 3 and pipe tunnel areas There are three classifications of Icaks: continuous small (0.1 5 lbs/sec); continuous intermediate (5 10 lbs/sec); and instantaneous release (25,000 lbs release). A small leak would be sirnilar to vapor discharge through a lb" safety valve or leaks in the system. Intermediate leaks could consist of leaking rnanways, cracked piping, or valven. The instantaneous release would be a cornplete failure '
of the tank car or ruptured piping.
As with most emergencies which require a Fire Brigade response, the Shift incident Commander assumes the responsibility of the scene leader. It should be noted that in the event of a chlorine leak:
- No two leaks will be the same
- If no action is taken the situation will only degenerate as time progresses It is imperative that the n;tuation be assessed quickly and action taken as soon as possible.
0AOP- %.0 Rev. 11 Page 8 o f 19
Extreme caution must be taken while in an area where free chlorine gas could be present.
Off-site Emergencies: Based on contractual agreements between Carolina Power 61.ight Company (CP&L) and Military Ocean Terminal Sunny Point (MOTSU), this procedure will be implemented to provide immediate emergency response to all chlorine emergencies while the chlorine tank car is being transported by MOTSU personnel outside the Brunswick Nuclear Plant owner controlled area. In the event of a chlorine emergency during transportation of the chlorine tank car, MOTSU personnel will contact the Main control Room at Brunswick Nuclear Plant.
Brunswick Nuclear Plant will activate an off site chlorine Emergency response team. HOTSU personnel will provide esecrt for the Chlorine Emergency response team from Brunswick to the secue of the emergency, and Chlorine Emergency response personnel will mitigate the consequenets of the emergency using all available means. A Brunswick Nuclear Plant vehicle vill be usen for transportation. If the Fire Brigade Command Vehicle is needed, an alternate means of towing the firo trailer must be established within 30 minutes, 5.0 BEEERENCIS (1) Plant i.ergency Plan l (2) 001 01.07 Notifications (3) Contractual Agreement Between CP6L and HOTSU R4 (4) LER 1 94 013 6 Condition Report 94 01769, Small Release of Chlorine Gas R5 (5) Condition Report 95 02591, CBEAP Boundary Negative Pressure 6.0 QIACRAMS/ATTAQJ]MENTS Attachment 1 Spatial Area Estimation Att:achmsnt 2, Off Shift Chlorine Response Personnel Activation l Attachment 3, Off Shift Personnel Beeper Call Back Codes Table 1, Continuous Gas Release @ 25 lbs cl/second (3.79 m'/sec) for Unstab,ln Atmospheric Conditions Table 2, Continuous Gas Release @ 25 lbs cl/second (3.79 m'/sec) for ticut ral Atmospheric Conditions Tabic 3, Cont.inuous Cas Release @ 25 lbs cl/second (3.79 m'/sec) for Stat}ln Atmospheric Conditions Form 1, Emergency Estimate for Cascous Release Surrounding the Brunswick Nuclear Plant Site OAOP.34,0 Rev. 11 Page 9 of 19 >
ATTACllMENT 1 Spatial Area Estimation To estimate the potential soatial area for concern during a hazardous material release, it will be necessary to obtain basic meteorological data and complete Form I which is attached to this procedure.
Obtain Meteorological Data:
- 1. Obtain the following' meteorological data from the BNP on site meteorological monitoring syntem and complete form 1:
hower wind direction: (deg.) this is the direction from which the wind is blowing.
Lower wind velocity: (mph)
If velocity is 0 to 5 mph . . . Light If velocity is 5 to 15 mph . . . Moderate If velocity is 15 or more . , . Strong Stability type: A B C D E F G (circle one)
If A, B, or C . . . . . Unstable if D . . , , . . . . . Neutral if E, F, or 0 . . . . . Stable
- 2. If the BNP Control Room cant.ot provide the required information, contact Murray and Trettel, Inc. (caronet 8 751 2918/2919 or Bell 919 362 2918/2919) or the National Weather Service (763 8331) at the Wilmington International Airport. Identify youracif and briefly describe the emergency which exists. Ask to speak to the Shift Forecaster On Ducy, and request-the following information from the Wilmington Airport flourly Observation:
Wind direction: (deg.) this is the direction from which the wind is blowing, Wind velocity: (mph)
If velocity is 0 to 5 mph . . . Light
-If velocity is 5 to 15 mph . . . Moderate if velocity is 15 or more . Strong Stability Type: Ask the Forecaster if the atmospheric stability from the surface to 500 feet would be classified as:

ATTACllMENT 1 (Cont'd)
- 3. If'neither the BNP Control Room, Murray and Trettel, Inc., or the r National Weather Service can be contacted for weather information, use ;'
the following to estimate conditions which exist at the accident site:
Wind Direction: Estimate the direction where. north should be. Face that direction and determine from which direction the i wind is COMING FROM (to your right will be East.. [
your left will be West.. from the front will be l
North., from the back will be South). '
(circle one) North Northeast East Southeast ;
South Southwest i West Northwest Wind Velocity: From the following, estimate the category which best describes the wind velocity; (circle one)
Light Wind felt on the face; leaves rustle; ordinary wind vanes are moved.
Moderate Leaves and small twigs on trees in constant motion; wind will extend a light flag. ,
Strong Raises dust and loose paper; small branches on trees are moved; small trees in leaf begin to sway.
Stability Class: Use the following to estimate the atmospheric stability affecting the release of gaseous materials. l
_(circle one) Stable Usually occur at night -Clear skies with calm winds h and cool surface temperature. Most likely to occur i in early morning (2 a.m. until. sunrise); also-if you observe rising smoke shich is suddenly stopped in vertical rise.
Neutral Occur during night or day: If skies are uloudy or !
if there is rain (or rainshewers) then the atmospheric stability is neutral. During evenings from the period of sunset to about 2am; conditions are most likely neutral.
Unstable Usually during the daylight hours: Skies must be cicar or mostly clear, usually during a warm day with winds moderate or strong. Winds tend to be gusty so that smoke dissipates rapidly.

ATTACliMENT 1 (Cont'd)
NOTE: Tables 1 through 3 are used for 25 lbs C1/sec releases.
Assistance from the TSC or engineerin6 may be required for I accurate plume spatial extents for other release rates.
MI 4 With the basic meteorological information, an estimate of the spatial extent of a plume can now be made. The followin6 should be done:
Unntable If the atmospheric stability is UNSTABLE, use Table 1 of this procedure. Under the appropriate wind velocity group and the concentration of conce.n, find the crosswind distance (in feet) and 1 the downwind distance (in feet or miles) where that area of equal concentration may be found.
Example: Moderate wind velocity and yov vant to find the area of 10 ppm. Use Table 1, look in the middle group under Moderate and under the 10 ppm column. At 0.25 miles downwind, the width of the pitme of material is 276 feet to the right of the center 11,,e...a total of 552 feet wide at 0.25 miles downwind. The plume is a total of 718 feet wide at 1.25 miles. The area of 10 ppm ended between 1.25 and 1.5 miles downwind of the release.
Neutral If the atmospheric stability is NEUTRAL, use Table 2 of this procedure. Under the appropriate wind velocity group and the concentration of concern, find the crosswind distance (in feet) and the downwind distance (in feet or miles) where that area of equal concentration may be found.
Example: Strong wind velocity and you want to find the area of 10 ppm. Use Table 2, look in the right hand group under Strong and under the 10 ppm column. At 0.25 miles downwind, the width of the plume of material is 284 feet to the right of the centerline. . .a total of 568 feet wide at 0.25 miles downwind. The plun.e is a total of 968 feet wide at 1.25 miles. The area of 10 ppm ended between 1.75 and 2.0 miles downwin) of the release.
Etoble if the atmospheric stability is STABLE, use Table 3 of this procedure. Under the appropriate wind velocity group and the concentration of concern, find the crosswind distance (in feet) and the downwind distance (in feet or miles) where that area of equal concentration may be found.
Example: Light wind velocity and you want to find the area of 1000 ppm. Use Table 3, look in the left hand group under Light and under the 1000 ppm column. At the widest point of the plume, 1.50 to 1.75 miles from the release point, the plume is only 98 feet to the right of the centerline..... a total of 196 feet wide. Iloweve r , the 1000 ppm concentration ends between 2.75 and 3.00 OAop.34.0 Rev. 11 Page 12 of 19
e ATTACitMENT 1 (Cont'd) miles from the release point. Under stabic conditions and j light winds very small concentrations of gaseous material ;
will travel very far downwind provided no other factors i act upon the dispersion of the pleme. ,
i
- Critical Notes ***
i t
- 1. Under stable conditions and light wind speeds, gaseous. plumes of released material will travel in concentrated form for great distances, provided that no other influences act upon the plume, ,
- If the wind does not remain steady in any direction, the plume will not ;
remain concentrated at extended distances, but will disperse the material within a much smaller area. Observation of the wind direction is important not only to estimate the downwind aret.s of concern, but to assist in the determination of potential cor.centrations of released mat 9 rial.
- If there are any close by structures, lar6e bodies of water or_ wooded ;
areas to where the release point is lost ?d, these influences could locally affect _the wind direction and verucities observed. Large objects will direct the wind flow and reduce the velocity. Within'a downwind distance ten times the height of a large object, wind direction and velocities will be influenced, thus caution should be exercised in concentration determination. ;
- 2. The wind direction reported by meteorologists and the L.unswick Control Room personnel is the wind direction IRQM where the wind is coming l Caseous material released from a source will travel 180* opposite from the wind direction being reported by observation, therefore, in order to have the correct direction _for possible_ actions to be taken.-the opposite direction from which the wind is being reported must be used. '
- 3. Meteorological data obtained-from the on site meteorological monitoring system, Murray and Trettel, Inc. , or from the National Weather Service will use compass directions. " Plant North" is rotated 45' to the cast of compass north.
