I located at the Sharpe Station (Figure 2.2-1) and at a point 4

1.5 miles wes t-southwest of the Sharpe Station.

1 l Three of the Phillips petroleum pipelines carry refined pro-ducts; the oth r two carry crude oil. The refined products pipelines are 8, 12 and 16 inches in diameter and pass within 4

3.0 miles of the plant site. The 8-inch products pipeline was. built in 1930, carries a maximum of 45,800 barrels per I day, and operates at 1,080 psig. The 12-inch products pipe-line was built in 1952, carries a maximum of 92,000 barrels per day, and operates at 1,180 psig. The 16-inch products pipeline was built in 1980, carries a maximum of 100,000 barrels per day, and operates at 960 psig. The hydrocarbons transported through these lines are propane, butane, iso-E butane, iso-pentano, No. 8 Natural Aviation gasoline, furnace oil, stove oil, diesel fuel, and kerosene. All of these hydrocarbons are flammable. See Tabic 2.2-1 for the distances from the plant site for each pipeline.

The crude oil pipelines are 10 and 12 inches in diameter and pass within 2.6 miles of the plant site. The 10-inch crude oil pipeline was built in 1947, carries a maximum of 30,000 barrels per day, and operates at 1,080 psig. The 12-inch crude oil pipeline was built in 1975, carries a maximum of 62,000 barrels per day, and operates at 1,158 psig.

The Phillips natural gas pipeline is 8 inches in diameter and parallels the route of the crude oil lines. The gas pipeline was built in 1933, carries a maximum of 3 million cubic feet por day, and operates at 960 psig.

None of the lines are used for gas storage and there are no 4

plans to use the pipelines to carry other products (Hayes, i 1979; Jonas, 1979; and Miller, 1978).

The natural gas pipeline operated by the Union Gas Company is l 8 inches in diameter. It terminates 4.7 miles southwest of the plant site. From there, the gas is distributed throughout

the city of Burlington. It was constructed in 1966 and is buried at a depth of approximately 24 inches. The maximum

! operating pressure is 70 to ~2 psig. Nordstrom plug valves

are located at the termina*1on point in Burlington. The pipeline carries only natural gas and there are no plans to use the pipeline for other products. The pipeline is not used for gas storage at higher than normal pressure (Caudell, 1979). There are no natural gas storage' facilities within 5 miles of the plant site (Veteto, 1978). Pipeline routes are shown on Figure 2.2-1.

2.2.1.7 Projections of Industrial Growth Projected growth for the various nearby industries listed in this section is expected to be minimal and thus will pose no future conflicts with the plant. This projection Rev. 9 2.2-12

s SNUPPS-LC The potential hazards associated with the ignition of vapor clouds which would form as a result of an accidental rupture i'n the 12 or 16-inch refined products (propane was considered for this analysis) and the 8-inch gas piplines have been evaluated. For each pipline, maximum rates of discharge were calculated assuming double ended (guillotine) pipeline break and frictionless and infinitely long pipelines. The horizontal motion and the configuration of the gas cloud were determined for each pipeline rupture from a gas dispersion analysis using a Gaussian plume model. The model determines the extent of the flammabic region of the cloud for a given meteorological condition, by calculating the gas concentration as a function of time and space coordinates relative to the point of release. The elevation of the centerline of the flammable region as a function of downwind distance from the source and time was determined.for the natural gas line using a plume rise model.

All seven atmospheric stability classes and six wind speed conditions selected as the averages of the intervals given in Section 2.3 were considered in~the analysis. The concen-tration limits of 2.8 percent to 7 percent gas by volume were used to define the flammable region of the cloud for propane. The corresponding limits for natural gas were assumed to be 5 percent and 15 percent. Through this analysis the volume and centroidal location of the flammable cloud relative to the plant were calculated.

The equivalent TNT mass yield recommended in Regulatory Guide 1.91 of 240 percent was used to calculate the weight of the flammabic volume of the cloud.

The detonation hazards were determined by calculating the yearly probability of exceeding one psi overpressure at the plant. Combinations of various rupture locations, meteoro-logical conditions and detonation times were evaluated in estimation of this probability. The probability of exceeding the one psi overpressure at the plant from each pipeline was calculated by dividing the line in question into a number of segments and by performing a similar analysis which was described as acceptable in NUREG-0014, " Safety Evaluation Report for Hartsville Nuclear Plants". For each segment the point closest to the plant on the segment is chosen as the assumed point of rupture. On this basis the probability of overpressu re haza rd, P, at the plant per year from a pipeline is calculated by NP 7 6 8 16 P =P E E E E X P (S,V,D)xPt(T)xL(N)xd(S,V,D,T,N) d N=1 S=1 V=1 T=1 D=1 w where:

Rev. 9 2.2-15

SNilP PS -D :

P probability of detonation per year per mile of pipe-d line; PW(S,V,D) = probability that wind of Stability Class S, Speed V and Direction D is blowing when detonation occurs; P (T) = probability that detonation occurs between times T

T =T and T 1 ^2 2 =T+^2 #

L(N) = length of pipe segment N, in feet; NP = number pipeline segments considered in the analysis; 1 if overpressure. exceeds the one psi d(S,V,D,T,N) = criterion for S ,V,D,T,N 0 if overpressure does not exceed the one psi criterion The values of P and P used in the above expression are basedongaspihelinebuptureandexplosionratesandmean time to detonation reported in the Preliminary Safety Analysis Rgport for Hartsville Nuclear Plants. They are:

P =7.7x10 detonations per year ~per mile of pipeline and P d(T)=exp(-T /B7)-exp(-T,/By), where the mean time to dbtonation B =6.6 minutes The probabilities of pipeline accident in which a detonation occurs resulting in an ovgrpressure at the plant in excess of one psi, ayg: 1.3x10 per year for the 16-inch propano line, 4 gx10 per year for the 12-inch propane line and 7

5.1x10 per year for the closest 8-inch natural gas line.

These probabilities are less than the value of 10- per year listed in Section 2. 2. 3 of Regula tory Guide 1.70, Rev. 3, for these three pipelines. The. remaining four pipelines within 5 miles of the plant do not constitute a greater source of hazard. Based on these facts, it is concluded that accidental rupture of nearby pipelines need not be considered as design basis events.

The Phillips Pipeline Company has an 80,000-gallon propane tank and an unused butane tank of 24,486-gallon capacity, 3.2 miles north of the plant site at Sharpe. Any accidental rupture of the propane tank may lead to a vapor cloud forma-tion. A continuous release rate of 300 lb/sec is conserva-tively assumed which corresponds to a rupture of 6 inches in diameter in the wall at the bottom of the tank. Using a wind speed of 5.25 ft/sec, the ratio of mass flow release rate and wind speed is calculated as 57 lb/ft. The 1 psi overpressure safe standof f distance under the most stable weather condition is obtained from Cichler, Napadensky, and Mavec as 2.5 miles. Since this distance is smaller than Rev. 9 2.2-15a

fin tl l'I':;-h _'

the actual distance between the propane tank and the plant structures, an accidental Icakage of the tank contents does not pose any hazard to the plant structures.

2.2.3.1.3 Toxic Chemicals There are no industries in the plant vicinity using or pro-ducing toxic chemicals.

Chlorine is stored as a liquid in 1-ton storage vessels at a distance of approximately 2000 feet from the control room l

l air. intake and in ISO-pound vennels approxiantely 475 feet from the control room air intake. These vessels are pro-vided with fusibic metal type safety relief devices to pre-vent rupture. Even if there is any accidental release of chlorine, it will not affect the control room habitability. ,

i See Section 2.2.3.1.6 for a further discussion of the onsite '

chlorine accident analysis. Similarly, the onsite storage  !

of carbon dioxido does not pose any hazard to the plant oper-ation.

2.2.3.1.4 Fires i Since there are no industrial or military installations near the plant and the transportation routes carrying flamnabic material are at a sufficient distance form the station as i described in Section 2.2.1.4, the plant is not exposed to any '

fire hazard. The plant fire protection system will be able t

to handle brush fires in the vicinity of the plant.

! 2.2.3.1.5 Collisions with Intake Structures There is no commercial water traffic on the John Redmond

) Reservoir or on the cooling lak'c. Thus, there is no poten-

ti'al for collision of vossols with the intake structure.

2.2.3.1.6 Liquid spills There is no commerciai water traffic on the cooling lake.

Recreational boats and service stations are not capable of producing liquid spills in significant amounts. The maximun loss for the pipelines located about 3 miles from the site is estimated to be approximately 2,000 barrels of hydrocarbons.

] The loss due to seepage cannot exceed 24 barrels. Because the piplines pass under a small floating spill in the northern area of the cooling lake. The screen house of the plant is separated from this area by baffic dike "A" and by the central portion of the cooling lake, so that the travel-

, ing distance for the spill to reach the screen house is over j 6 miles. Furthermore, a very special meteorological condition involving wind changes tined to the spill movement aculd i

be required in order for the intact spill to approach-channels Icadin'g to the screen house. Therefore, liquid spills do not pose a hazard to the safe operation of the plant.
