BIG ROCK POINT PLANT SEP SAFETY TOPIC EVALUATION TOPIC III - 4.D SITE PROXIMITY MISSILES (Including Aircraft) 1.
INTRODUCTION The objective of this Systematic Evaluation Program (SEP)
Topic is to ensure that the integrity of the safety-related structures, systems, and components will not be impaired and that they will perform their safety functions in the event of a site. proximity missile.
2.
CRITERIA Standard Review Plan Section 3.5.1.5 states that:
"The plant is considered adequately designed against site proximity missiles if the resulting probability of a missile affecting the safety-related features of the plant is within the guidelines established in Section II of Standard Review Plan 2.2.3."
Section II of Standard Review-Plan 2.2.3 states:
"The identification of design basis events resulting from the presence of hazardous materials or activities in the vicinity of the plant is acceptable if the design basis events include each postulated type of accident for which the expected rate of occurrence.of. potential exposures in excess of the 10CFR Parc 100 guidelines is estimated to exceed the NRC Staff objective of approxi-mately 10-7 per year.
Because of the difficulty of assigning accurate _ numerical values to the expected rate of unprecedented hazards generally considered in this review plan, judgment must be used as to the acceptability of the overall risk presented."
3.
DISCUSSION The potential for hazardous activities resulting from nearby industrial, transportation, and military. facilities in the vicinity of the Big Rock Point nuclear plant has been addressed in SEP Topic II-1-C.
However, this topic will address all'possible site proximity missiles, including those previously discussed in the above SEP topic report.

4 A.
TRANSPORTATION ROUTES 1)
Highways The nearest highway that services the Charlevoix and Big Rock Point nuclear plant areas is U.S.
Route 31.
This two-lane, blacktop road is located 2,760 feet from the plant at its closest point.
This highway is the main artery between the cities of Petoskey and Charlevoix.
Local shipments of fuel oil and gasoline, along with limited shipments of explosives (ammonium nitrate) used at the local limestone quarry, pass by the plant on Route 31.
~There are no other known regular shipments of explosive chemicals along Route 31 in the Big Rock Point area (1).
The distance between the highway and the Big Rock Point nuclear plant exceeds the minimum distance criteria given in Regulatory Guide 1.91 for truck-load shipments of explosive materials.
Therefore, it is concluded that an explosive accident on Route 31 will not adversely affect the safe operation of the plant.
2)
Railways A Chesapeake & Ohio (C&O) Railroad branch line runs approximately 5,600 feet south of the plant at its closest point.
Information obtained from the railroad company indicates that three freight trains per week, providing local service only, use the line.
The railroad company identifies propane as the only hazardous material shipped on the line.
We have evaluated the consequences of a postulated explosion on the railroad in accordance with the guidance in Regulatory Guide 1.91.
The distance between the railroad line and the plant exceeds the minimum criteria given in the regulatory guide for railroad shipments of explosive raterials and, therefore, is acceptable (2).
A railroad spur off the main C&O Railroad line goes into the plant.
This spur has been used sparingly in the past for transporting fuel bundles and other related equipment.
No explo-sive-type material has been or is expected to be transported into the plant area on this railroad spur.
Subsequently, no proximity missiles are postulated from the railway facilities.
3)
Waterways The Charlevoix harbor, located approximately 4 miles south of the plant, is a large recreational harbor used primarily for pleasure boating.
However, some commercial ships use the harbor.
The majority of this commercial traffic includes shipping coal for a fossil fuel power plant on Lake Charlevoix, limestone and cement from a nearby cement manufacturing plant, and occasional fuel oil and gasoline shipments to Beaver Island (approximately 31 miles northwest of Charlevoix).
The fuel oil and gasoline are transported by barge to Beaver Island no more than 20 times a year.
The closest these barges come to the plant is 4-1/2 miles, assuming a direct line between Charlevoix Harbor and the city of St. James on Beaver Island.
Regular Lake Michigan commercial shipping lanes are approxinately)15 miles away, at the closest point to the plant (3 The distances between the commercial shipping lanes and-the Big Rock Point nuclear plant exceed 1
the minimum distance criteria provided in Regulatory Guide 1.91.
It is therefore concluded that an explosive accident along the shipping lanes will not have an adverse effect on the-safe operation of the plant.
B.
AIRPORTS 1)
Commercial The closest airport to the Big Rock Point nuclear plant is the Charlevoix airport, located approximately 5 miles to the southwest.
The airport is a general aviation facility used by light aircraft for charters, business, and recreational activities.
The airport consists of one blacktop runway (75 feet wide by 3,500 feet long), oriented in the east-west direction.
This runway handles approximately i
90% of all air traffic in and out of Chnrlevoix.
In addition, there are two turf runways,-1,310 feet l
long and 1,550 feet long. In 1980, there were i
approximately 12,000 takeoffs or landings, with i
approximately half of these flights to or from Beaver Island.
Currently, there are approximately 20 planes based at the airport.
Future plans for i
airport expansion are limited 'to : extending the l
main runway from 3,500 feet to 4,500 feet in the spring of 1982(4).
The Emmet County Airport (located in Pellston, Michigan) is the closest commercial airport handling regularly scheduled passenger and freight traffic.
The majority of commercial flights out of this l

l-
t-e i
airport are " commuter hops" to Traverse City or-
- Sault-Sainte Marie. The flight paths are-straight runs between airports at an altitude of approx-imately 6,000 to 12,000-feet.
The flight to and from Traverse. City comes no closer than~8 to 10 4
milestotheyggtheast:ofthe'BigRockPoint nuclear plant
- As identified in SEP Topic II 1 C there is no.
" undue risk to the safe operation of the nuclear
-plant and mygys the acceptance criteria of SRP 2.2.3."
In addition, it is concluded that commercial airplanes:will have no adverse effect on the safe operation of the Big Rock Point nuclear plant.
2)
Military Maneuvers
{-
Bayshore Radar Station, located approximately 4-1/2 miles east of the plant, is used by the United.
States Air Force as a tracking station for simu-lated bombing runs.
The flight.corridorLused for these simulated bombing runs is over-Lake Michigan and is used primarily by the. Strategic Air Command B-52s and FB-llls. It is also used occasionally by j
the National Guard.
No live weapons / bombs are involved in these simulated bombing runs.
The established corridor used by these planes is i
approximately 10 miles wide._ The centerline of 1:
the corridor is located approximately'15 miles-I from:the plant at its closest point.
These military planes flyfat an-altitude between 400 and 1,200 feet, depending. ort the weather. : All military; planes in this corridor are: tracked on radar,-~and i
any plane that deviates from this corridor'is immediately notified to correct position.
In
' addition, all military planes in the-corridor have flight plans clearly showing the corridor boun-daries, and all have instructions to stay within these borders (6)
As identified.in SEP. Topic II-1.C(2), a risk' assess-i ment was undertaken by the U.S. Air Force, which concluded thatithe probabil plant was approximately 10-gty of a crash at=the
[
per year.
This study-l was based on the corridor centerline located only.
L 6.5 miles from the plant. -Subsequent to this study,-
i the corridor centerline was. located 15 miles at-i the closest point from the-plant.
The-of a crash is 'now even lower than '10-8. probability -

the military activity in.the. area does not pose an' unreasonable risk to the safe operation -of the plant (2),
C.
UNDERGROUND LINES
.The closest. underground pipeline is a 6-inch diameter.
natural gas line' owned by' Michigan' Consolidated Gas-Company,1which is located approximately 1-1/2 miles.
south of the plant (7).
Based on evaluations of pipe-line accidents conducted for previous licensing reviews, a pipeline accident, at this distance, will not affect the safe operation of'the plant (2).
There are no gas or oil production fields, underground storage facilities, or refineries in the vicinity of the plant.
D.
INDUSTRY The closest industrial' complex to the Big-Rock Point nuclear plant is a plastic molding processing plant located approximately 1/2' mile from the power plant, adjacent to the eastern property line of Consumers-Power Company.
This plant, which produces custom molded plastic fixtures, employs 126 people and pro-cessed 5 million plastic pellets last year.
The materials stored at this facility are 'not of an explosive nature, except for small' quantities'of paint thinner (8),
A small industtial park is located approximately 2-1/4~
miles' southwest-of the plant.
Several light manufacturing companies, employing (a total of about 200 persons, are.
located in the park. 2)
A survey made at oneLof the larger employers in this' industrial park revealed that the only sources of potential explosives are small quantities of paint thinner and welding gas tanks. I9)
No hazardous materials in quantities large enough'to i
affect the safe operation of the nuclear-plant are-known to be processed, stored, or' transported in the industrial p. ark.
A 10 kW windmill-type generator is located approximately-3 miles southwest of the plant and is approximately 100 feetLabove the' ground. ~There is sufficient distance between the plant and the windmill-type generator.to
~
have no impact on the operation of'the plant.(10)
A large cement manufacturing. facility and a quarry are located approximately'6 miles from the Big Rock ~ Point-nuclear plant and are,far'enough away tc have no impact on tne operation of the plant. (ll)
In conclusion, there are no industrial hazards in the vicinity of the Big Rock Point nuclear plant that could affect the safe operation of the plant.
F.
GENERAL The city of Charlevoix is the largest city in Charlevoix County and is located approximately 4 miles southwest of the Big Rock Point nuclear plant.
The year-round population of Charlevoix County in 1980 was 19,907, with a projected year-round population of 27,600 in the year 2000.
The year-round population of Hayes Township (location of the Big Rock Point nuclear plant) in 1980 was 1,274, with a projected year-round population of 2,400 people in the year 2000.
The main industry in this area is tourism, with peak summer population occurring in June, July, and August.
The average daily population of Charlevoix County during this period is approximately 33,000 people.
The area along Route 31 adjacent to the Big Rock Point nuclear plant is zoned industrial.
However, future expansion in this area is doubtful because the subsurface limestone fields make for and sanitation wastes (12). poor drainage of industrial 4.
CONCLUSIONS Externa]Iy generated missiles resulting from the nearness of airports, transporation routes, and industrial and military facilities are not postulated for. the Big Rock Point nuclear plant, therefore, no specific protection is required for proximity missiles.
