SEP Topic II-1.C, 'Potential Hazards Due to Transportation, Institutional, Industrial and Military Facilities" R. E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Crutchfi;eld:
Enclosed is the Rochester Gas and Electric assessment for SEP Topic II-1.C, "Potential Hazards Due to Transportation, Institutional, Industrial and Military Facilities".
This assessment for the R.
E. Ginna site is,modeled upon the NRC's assessment of this topic for Consumers Power Company's Palisades plant, issued by letter from Dennis L. Ziemann, NRC, to Mr. David Bixel,
- CPCO, dated November 27, 1979.

SEP To ic II-1.C Potential Hazards Due To Trans ortation Institutional, Industrial and Militar Facilities R.E. Ginna Nuclear Plant Puzuose The safety objective of this topic is to ensure that the Ginna Nuclear Plant is adeguately protected and can be operated with an acceptable degree of safety with regard to potential accidents which may occur as the result of activities at nearby industrial, institutional, transportation, and military facilities.
The review was conducted in accordance with the guidance of SRP's 2.2.1, 2.2.2, 2.2.3 and 3.5.1.6, as well as Regulatory Guide 1.91, Rev. l.
Descri tion There is little industrial activity in the vicinity of the Ginna plant.
Wayne County, where Ginna is located, is primarily a rural area.
Typical industries for Wayne County are shown in Table 2.5-1 of the FSAR,.reproduced here as Table 1.
The nearest concentration of industrial activity is located in the town of Webster, about 6
miles from the site, and consists primarily of light manufacturing (Xerox copiers).
No industrial development is expected to occur in the vicinity of the Ginna site.
The nearest transportation routes to the plant. are Lake Road and U.S. Route 104, which pass about 1700 feet and 3 1/2 miles, respectively, from the plant at their closest point of approach.
The guidance of Regulatory Guide 1.91, Revision 1, was utilized, to evaluate the consequences of postulated explosions on Lake Road.
Regulatory Guide 1.91, Revision 1, has been specifically identified by the NRC's Regulatory Requirements Review Committee as needing consideration for backfit on operating reactors.
The highway separation distances at Ginna exceed the minimum distance criteria given in the Regulatory Guide and, therefore, provide reasonable assurance that transportation accidents resulting in explosions of truck-size shipments of hazardous materials will not have an adverse effect on the safe operation of the plant.
It is important to note that no hazardous cargo would be expected to be transported along Lake Road.
This road is used primarily for local traffic, such as that relating to the apple processing plants.
No industry using large quantities of explosives is located along this route.
Any large quantities of hazardous material would be shipped via U.S. Route 104, which, at 3 1/2 miles from the plant site, is sufficiently distant not to be of concern.
Highway accidents on Lake Road involving certain hazardous chem-icals could theoretically exceed toxicity limits in the plant.
control room assuming an optimum set of spill'arameters and atmospheric dispersion conditions.
However, the highway separation distances and the lack of any indication of frequent shipment of hazardous chemicals past the plant (since shipment would be along U.S. Route 104), provide reasonable assurance that the likelihood of a hazardous chemical spill affecting the operation of the plant is low.
However it. cannot be precisely determined what. the proba-bility of a hazardous chemical accident would be, because detailed
information on the size,
- type, and frequency of hazardous chemical shipments past the plant is not available.
Although it is con-sidered that the probability of a hazardous chemical transportation accident affecting plant operation is low, we believe that the F
possibility of such an accident, should be one of the factors i
I considered in the final evaluation of the adequacy of the control room habitability systems for the Ginna Plant.
This matter will be evaluated further under NUREG-0737, item III.D.3.4, "Control Room Habitability".
The nearest railroad to the plant is the Ontario Midland railroad about 3 1/2 miles to the south.,
Comparing this distance with the guidance provided in Regulatory Guide 1.91, it is apparent that potential railroad accidents involving hazardous materials are not, considered to be a credible risk to the safe operation of the plant.
The nearest large pipelines to the plant are a 12" gas line located about six miles southwest of the plant, and a 16" gas line located about 10 miles south of the plant.
These pipelines are far enough removed to assure that pipeline accidents will not affect the safety of the nuclear plant.
Figure 3 shows a portion of the residential gas lines serving homes along Lake Road, as well as the house heating boiler at the Ginna plant itself.
There are no gas or oil production fields, underground storage facilities, or refineries in the vicinity of the plant.
There are no large commercial harbors along the southern shore of Lake Ontario near the plant.
Some freight is shipped through Rochester harbor about 20 miles to the west.
Major shipping lanes in the lake are located well off-shore, at least.23 miles or more, from.,the plant.
- Thus, lake shipping is not considered 7
40 to be a hazard to the plant.
The closest airport. to the plant is the Williamson Flying Club Airport, a small privately-owned general aviation facility located approximately ten miles ESE.
Monroe County Airport, in Rochester, New York, located about, 25 miles southwest of the plant, is the nearest airport with scheduled commercial air service.
Low altitude federal airways V2 and V2N pass about 10 miles south and 2 1/2 miles, southwest of the plant, respectively.
An Air Force Restricted Area R-5203 is located about. eight miles north of the plant site.
Whenever flight activity is conducted by the Air Force within R-5203, radar surveillance is maintained by the 21st NORAD Region, the 108th Tactical Control Group, or possibly the Cleveland Air Route Traffic Control Center.
Pilots rely upon on-board navigational equipment to maintain their presence within the specified limits of the restricted area.
Pilots can also be advised if their aircrafts stray beyond their limits by the radar surveillance unit covering the area at the time.
The restricted area is used daily for military flight training which includes high-speed interceptor training maneuvers, operational flight checks, and air-to-air refueling.
The current altitude ranges from 2,000 to 50,000 feet above the surface.
A
portion of the Detroit Sectional Aeronautical Chart, reproduced as Figure 1, shows the airports, air routes, and training space described above.
The Williamson Flying Club Airport has one paved runway.
This runway, designated 10-28 and thus oriented in an almost east-west.
'W direction, is 3377 feet long and 40 feet wide.
The main runway is equipped with low intensity runway lights.
The airport has instrument approach capability to runway 28 from the Rochester VORTAC.
Figure 2 shows the instrument flight path.
There is no control tower at this airport.
The airport is used for general.
aviation activities such as business and pleasure flying, and for agricultural spraying operations.
There are currently about, 5,000 operations per year at the facility, and about 30 based aircraft, including part-time based crop dusters.
The great majority of the aircraft are single-engine propeller airplanes which typically weigh on the order of 1500 to 3600 pounds. 8 The low altitude federal airways, V2 flights per day.
Almost all flights and V2N, serve about 19 use V2, with V2N being used only occassionally.
At most, 10% of airline traffic would use V2N.
The width of these airways are eight miles. 9 Evaluation Based on distance from the reactor, it has been determined that truck and seaway traffic, railway transportation, and large gas and oil pipelines are not of concern to the Ginna safety-related equipment, with respect to the potential for detonation of explosives.
With respect to hazardous chemical shipments and the potential
I f'
effect on control room habitability, the Ginna plant will be further evaluated through NUREG-0737, item III.D.3.4.
Aircraft hazards to Ginna were reviewed against the criteria in SRP 3.5.1.6.
Acceptance criterion II.2 states that, for military air space, a minimum distance of five miles is adequate for low 4
~
level training routes, except those associated with unusual activities, such as practice bombing.
Air Force Restricted Area R-5203 is about eight miles from at its closest boundary, and no unusual activities such as practice bombing take place.
This criterion is met.
Section III.2 of SRP 3.5.1.6 states that the probability of an aircraft crash into the plant should be less
-7 than about 10 per year.
This probability can be evaluated using the relationship:
P
=
C x N x A/w where:
C = inflight crash rate per mile for aircraft using airway (assumed to be 3 x 10
)
w =
width of airway (plus twice the distance from the airway edge to the site when the site is outside the airway) in miles, N
= number of flights per year along the airway, and A
= effective area of plant in square miles
= 30 acres-0.5 miles For airway V2, P
= (3 x 10
) x (19 x 365) x
= 5.1 x 10
-9
.05
-8 FA 20
where W = 20 is derived from an air width of 8 miles
+ twice the six-mil'e distance from the airway edge to the site.
For airway V2N (assuming 10% of the 19 flights),
P
= (3 x 10
) x (2 x 365) x
= 1.4 x 10
-9
.05
-8 FA
.8 Since these values are below 1 x 10
, it is apparent that commercial air traffic over Ginna is not of concern.
Section III.3 of SRP 3.5.1.6 states that the probability of an aircraft crashing into the site should be estimated for cases where either of the following apply:
ll a.
An airport within five miles of the site.
b.
An airport. with projected operations greater than 500d movements per year is located within ten miles of the site, or an airport within projected operations greater than 1000d movements per year is located beyond ten 2
miles from the site, where "d" is the number of miles from the site.
The only airport potentially of concern is the Williamson Flying Club Airport.
This airport is about 10 miles from the site, with expected operations of 5000 per year.
This is substantially fewer 2 =
than the 500d
= 500 (10)
= 50,000 movements per year which would be of concern.
There is therefore no need to evaluate the proba-bility of an aircraft crash from this airport.
Conclusions The R.E. Ginna site meets a current regulatory criteria for "Potential Hazards Due to Transportation, Institutional, Industrial
k
and Military Facilities", except possibly for the consideration of hazardous chemical highway transportation accidents on Lake Road.
Although this latter issue is not expected to be of concern, since hazardous materials would be expected to be transported along U.S.
Route 104, which is 3 1/2 miles from the site, the j.ssue will be 11 I
4 further considered in the evaluation of Control Room Habitability as part of the NUREG-0737 item III.D.3.4 review.
Since the only potential deviation from current regulatory criteria is to be addressed outside of the SEP, it is considered that SEP Topic II-1.C is complete for Ginna, and no additional evaluation will be required for this topic within the SEP.
