~ ~ _ _ _. _ t h SYSTEMATIC EVALUATION PROGRAM TOPIC II-1.C HADDAM NECK TOPIC: II-1.C, Potential Hazards Due to Nearby Transportation Institutional Industrial and Military Facilities I. INTRODUCTION The safety objective of this topic is to ensure that the integrity of the safety-related structures, systems and components would not I be jeopardized due to the potential for hazards originating at nearby l facilities. l II. REVIEW CRITERIA i l General Design Criterion 4, " Environmental and Mi.ssile Design Basis,". l - of Appendix A, " General Design Criteria for Nuclear Power Plants," to I 10 CFR Part 50, " Licensing of Production and Utilization Facilities," requires 'that nuclear power, plant structures, systems and components important to safety be appropriately protected against events and conditions that may occur outside the nuclear power plant. III. RELATED SAFETY TOPICS l Topic III-4.D, " Site Proximity Missiles" reviews the extent to which the facility is protected against missiles originating from o.ffsite ~ I l facilities. l IV. REVJEW GUIDELINES ~ The review was-conducted in accordance with the guidance given in Standard Review Plan (SRP) Section 2.2.1-2.2.2, " Identification of Potential Hazards in Site Vicinity." ~ V. EVALUATION The Haddam Neck Plant site is located in the Town of Haddam, Connecticut on the east bank of the Connecticut River at a point 21 miles south-southeast of the Hartford, Connecticut and 25 miles northeast of New Haven, Connecticut. The site consists of approxi-mately 525 acres. The minimum distance from the reactor containment l to the site boundary is 1,740 feet.and the distance to the nearest

- ____..E___.__. ^ 2 a_ _ __. u _ _ _._ _ residence is over 2,000 feet. The largest nearby city is Middle-town, Connecticut, which is approximately 9.5 miles from the Haddam Neck Plant site. The adequacy of the population center distance will be determined as part of SEP topic II-1.B. Populat' ion Distribution. The largest industrial complex within 10 miles of the Haddam Neck Plant site is the Pratt and Whitney Plant in the Maromas section in Middletown, which is about 6 miles northwest.of the.Haddam Neck Plant on the west side of the Connecticut River. Approximately 3,600 people are employed at the Pratt and Whitney facility. CYAPC0 has determined that the Pratt and Whitney plant has no effect on the safe operation of the Haddam Neck Plant and does not pose any potential hazard. Other industries located within 10 miles of the site which employ 250 or more people are as follows: Business Location Distance Employees North & Judd Co. Middletown 10 250 - 500 i Raymond Engineerins Laboratories Middl etown 10 250 - 500 EIS Automotive Corp. Middl etown 10 250 - 500 UARCO, Inc. Deep River 7 380 Middlesex Memorial Hospital Middletown 10 1,400 CYAPCO has concluded that because of the nature of these industries and,the distance from the Haddam Neck site, these facilities do not pose a potential hazard to the Haddam Neck Plant. A review of the Haddam Neck Plant site and surrounding area was per-formed to determine the types and quantities of hazardous chemicals stored on site or within a five mile radius of the site. In accor-dance with the requirements of Regulatory Guide 1.78, sulfuric acid was determined to be the only chemical stored on site in sufficient quantity to warrant further consideration. The potential for a sulfuric acid release which might endanger the safe operation of the plant will be determined in the evaluation for TMI Action Plan Item III.D.3.4, Control Room Habitability. No significar.t quantities of hazardous chemicals have been identified in the five mile radius area surrounding the site. 4 ~ .I t -s a

.a ._.i,_. s The nearest major highway which would be used for frequent trans-portation of hazardous materials is State Route 9, which is lo.cated at a distance.of about 4 miles from the Haddam Neck Plant site. CYAPC0 has determined that this separation distance exceeds the minimum distance criteria given in Regulatory Guide 1.91, Revision 1, and therefore provides assurance that any transportation accidents resulting in explosions of truck size shipments of hazardous materia'ls will not have an adverse effect on the safe operation of the plant. This separation distance should also eliminate the possibility of a toxic gas release adversely affecting the safe tperati6n of. the plant; however, this will be verified as part of Action Plan Item III.D.3.4, Contrgl Room Habitability. There are no railroad lines within 5 miles of the Haddam Neck Plant which are used to ship hazardous materials, therefore, rail trans- ' ' ~ portation does nat pose a hazard to the safe operation of the plant. In addition, there' are no pipelines or military facilities within 5 miles of the site which present any, credible hazard. ~ There is one airport within 5 miles 'of the Haddam Neck Plant site. Goodspeed Airport in East Haddam, Connecticut, is a general aviation facility with one runway located approximately three miles from the p.l ant..The airport is used primarily for light single engine air-craft activities such as business and pleasure flying. The location of the airport physically prohibits significant expansion. It was determined in the assessment of SEP Topic III-4.D, Site Proximity Missiles, that due to the size and nature of traffic, operation of the airport does not constitute a hazard to the plant. This conclusion was documented in Reference (5). l l-The U.S. Coast Guard was contacted to obtain information as to hazardous material shipping on t,he Connecticut River in the vicinity of the Haddam Neck Plant. The Coast Guard does not maintain records of hazardous chemical shipping, however, they did indicate that in their judgement no hazardous chemicals are shipped on the~ Connecticut River in the area of the plant on a regular basis. In addition, all shipping that is done on the river is, monitored by the Coast Guard to ensure that shipping is done in accordance with the applicable Federal regulations which in themselves provide for protection of public health and safety. The potential for a hazardous chemical release on tne river which would affect plant operation is being examined under TMI Action Plan Item III.D.3.4 Oil barges also travel on the Connecticut River within 1,000 feet of the site. The potential hazard due to missiles generated by oil barge explosions is addressed in SEP Topic III-4.D. l 4 [ w ( b /4 /m

L _.._ ._____4_- - - - - ._ Since the Connecticut River is used for shipping of materials, the potential for barge impact on the plant intake structure was examined. It is highly unlikely that a barge or ship could strike the intake. structure. The shipping channel near the site is on the far (west) side of the Connecticut River (

Reference:

USGS Quadrangles for Deep River and Haddam,.CT). All traffic ~must maintain a distance-of about 1000 feet from the intake structure under normal conditions. Should a ship become disabled, the natural river current would carry it along the west channel, downstream to the south, and well away from the intake structure at all times. Should a ship or barge approach the intake structure, sufficient protection exists to ensure safe operation of the plant. The barge would first contact one or both of the skimmer system pile clusters located 15 and 25 feet in front (to the west) of the intake structure (

Reference:

NUSCO drawing 16103-52005, Intake Structure Surface Boom). Should the barge continue on, it would be stopped by any co6bination of the 5 reinforced concrete abutments forming the west side of the structure (

Reference:

NUSCO drawings 16103-27058, Sh. 1 and 2, Arrangement /Screenwell, and 16102-14037, Plans, Elevations, and Details /Screenwell House). Failure of these structures would not affect operation of the service water pumps, located approximately 30 feet further back (east) or the circulating water pumps, located about 45 feet back (east). These pumps are all located to the east of-the trash racks and the traveling screens. Therefore, in ~' the extremely unlikely event of a barge or ship striking the intake structure, the plant would be adequately protected, - VI. CONCLUSIONS We ha,ve concluded that the Haddam Neck facility 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. Therefore, we conclude that Topic II-1.C is complete. ( n e
