YANKEE R0WE TOPIC II-1.C - POTENTI AL HAZARDS DUE TO NEARBY INDUSTRI AL, TRANSPORTATION, INSTITUTIONAL AND MILITARY FACILITIES The safety objective of Topic II-1.C is to assure that the nuclear power station
- is adequately protected and can be operated with an acceptable degree of safety with regard to potential accidents which may occur at neighboring industrial, transportation, institutional or military facilities.
The review for Yankee Rowe was evaluated in accordance with USNRC Standard Review Plan, Sections 2.2.1, 2.2.2 and 2.2.3.
Industrial activity in the vicinity of the Yankee Rowe station is minimal.
The only manufacturing or storage facility within five miles is the Deerfield Paper Company.
They do not store or use any hazaroous chemicals that could result in toxic fumes upon release into the ataosphere.
The closest industrici gas supplier is H.A. George, located approximately 10 miles southwest of Yankee Rowe.
They have two large LPG storage tanks having maximum capacities of 12,000 and 20,000 gallons and three LPG delivery trucks having maximum capacities of 1,200, 2,400 and 2,600 gallons.
The maximum quantity of fuel oil is 75,000 gallons located in above ground storage tanks.
The separation distance between the H.A. George gas storage location and the nuclear plant is considered adequate to preclude accidents affecting the safe operation of Yankee Rowe.
No mining or quarry operations have been identified as being within 10 miles of the station.
For this reason possible truck-size shipments of explosives on nearby roadways were not considered as potential hazards to safe plant operation.
The closest military facility is Westover Air Force Base located outside of Springfield, approximately 50 miles southeast of Yankee Rowe.
A discussion of the ef fects of an on-site aircraf t impact can be found in SEP Topic Section III-4.D
" Site Proximity Missiles."
Hazardous chemicals have been identified as being shipped on an east-west rail line of the Boston and Maine Railroad, located at its closest point approximately i
four miles from the south side of the site.
The evaluation of possible control room infiltration of toxic fumes from potentially hazardous chemicals was done according to methodology in Reference (1) and criteria established in Reference (2).
An analysis was done for all shipments defined by Reference (2) as being frequent, i.e. 30 per year for rail traffic, and was based on the maximum concentration accident, in which the quantity of the hazardous chemical considered was the instantaneous release of the total contents of the largest tank car.
This is the worst case compared with partial ruptures in which the contents leak out in a continuous steady flow.
The concentration buildup in the control room was the sum of the concentration due to the immediate, highly concentrated puff for low boiling point chemicals and the continual vaporization of any remaining fluid.
Results indicate that hazardous chemical shipments via the rail line do not present a significant threat to the safe operation of Yankee Rowe.
.D s;.
The only major highway by Yankee is Route 2, an east-west road located at its closest point six miles from the station. There is not data presently available
~
that indicates frequencies, quantities and types of hazardous material that are shipped via tank trucks using this roadway. To determine the possible conse-quence of a truck accident involving hazardous material, an analysis was done assuming a sixteen ton chlorine tank truck rupture.
Chlorine was used because of its high toxicity when compared to other chemicals and its production (6th among all chemicals in 1972 ) exceeds other highly toxic, volatile chemicals 3
Results such as hydrogen cyanide and phosgene by nearly two orders of magnitude.
indicate that a chemical truck accident on the highway would not affect the safe operation of the plant.
There are presently no pipelines, gas or oil production fields, underground storage facilities, refineries or major waterways in the town of Rowe or in the surrounding area towns.
It can be concluded that the Yankee Rowe plant is adequately protected and can be operated with an acceptable degree of safety with regard to industrial, transportation, and military activities in the vicinity of the plant.
