Subject:

Waterford 3 SES Docket No. 50-382 License No. NPF-38 1996 Survey of Toxic Chemicals and Pipelines in The Vicinity  ;

of Waterford 3 Gentlemen:

Entergy Operations, Inc. is required according to Technical Specification 6.9.1.9 and 6.9.1.10 to perform a survey and analysis of toxic chemicals and pipeline explosive hazards within the immediate area of Waterford 3.

Provided in this submittal are the re=lts of the 1996 survey and analysis, it has been concluded based on the rescits that the effects of existing potential explosive and toxic chemical hazard sources are bounded by the analyses in the FSAR. One new hydrogen pipeline was addeo in the Fall of 1994. The potential explosive effects of this pipeline are bounded by the FSAR analysis.

The analysis of the 1996 survey results indicates the overall hazard probability (for incapacitation of operators) from toxic chemicals being transported by rail is approximately 2.9 x 10* per year. NUREG/CR-2560 suggests a value of 0.1 for the probability that incapacitation of the operators would lead to a radiological release in excess of 10CFR 100 guidelines. With this factor appiled, the probability that toxic chemicals freguently transported on this rail !ine could cause a radiological release is 2.9 x 10~ per year, which is well below the 104 per year criterion for accidents leading to radiological releases in 10CFR100.

RESULTS OF THE 1996 SURVEY OF TOXIC CHEMICALS STORED.

PROCESSED OR TRANSPORTED IN THE VICINITY OF WATERFORD 3 l

lNTRODUCTION f

i Technical Specification 6.9.1.9 for Waterford 3 requires Entergy Operations Inc. to perform an analyses of major industries in the vicinity of the plant which could have significant inventories of toxic chemicals on site to determine the impact on safety and submit the results to the NRC at least every four years. A report of the results I of the last such survey and analysis was submitted to the NRC by letter W3F192-0301, dated July 31,1992. A more detailed description can be found in Sections  :

2.2 and 2.2A of the Waterford 3 FSAR (Rev. 8). This report provides the results of the 1996 survey. A companion report (attached Report B) discusses the survey and analyses of pipelines and explosive hazards in the vicinity of Waterford 3.

TOXIC CHEMICAL SURVEY 1.0 Survey of Local Industries I

The 1996 survey of toxic chemicals in the Waterford 3 vicinity identified 15 1 industrial facilities which stored or processed such materials within a five mile radius of the Control Room. Regulatory Guide 1.78 specifies that sources more than five miles away need not be considered, since they are not likely to pose a hazard. One of these facilities, E.I. Du Pont De Nemours & Co., was omitted from the current survey since all structures containing toxic chemicals on its property are outside the five mile radius.

To determine if there were any other industrial facilities with significant sources of toxic chemicals in this area, the Local Emergency Preparedness Centers (LEPC's) of the Louisiana Parishes of St. Charles and St. John The Baptist were consulted.

State law requires that all hazardous chemicals stored anywhere in the parishes to be reported to the respective parish LEPC. The area encompassed by the five mile l

.radius es li within the boundaries of these two parishes. All facilities storing toxic chemicals have been assumed to have filed reports with the LEPC's.

These reports submitted to the LEPC's, entitled Tier Two Emergency and l

Hazardous Chemical Inventory, is in the form of an inventory for the previous calendar year and must be submitted annually prior to March 1. Additionally, this report includes the location of the reported hazardous materials.

f f The reports for the industries in St. Charles Parish were on file and reviewed in the St. Charles Parish Office of Emergency Preparedness. Data from the St. John The 4

1

, 1 l

)

Baptist Parish was obtained by contacting the facility by telephone. Data from the 1992 report were compared to these reports.

A listing of the facilities surveyed along with location is present in Table A-1.'

Table A-2, lists the names of the individuals signing the reviewed Tier Two reports.

The Tier Two reports provided sufficient information to enable a determination of the consequences in the event of a toxic chemical release accident. The survey results indicated that the types and quantities of sources of toxic chemicals have either remained the same or have been reduced or eliminated since the last survey.

2.0 Union Pacific Railroad Toxic chemicals that are transported on the tracks of the Union Pacific Railroad that pass approximately 0.45 mile south-southeast of Waterford 3 were included in the survey.

All material passing on the tracks that border Waterford 3 must pass through the Avondale Switching Yard located 16 miles southeast of the plant. Thus the railroad was able to prepare a computerized listing of the hazardous material shipments originating and terminating at the Avondale Switching Yard.

Table A-3, which includes hazardous materials shipped on the railroad tracks within five miles of Waterford 3 (including a few that might originate or terminate at Avondale but not pass the plant), lists 135 separate commodities. The number of cars containing each commodity passing over this portion of the tracks in 1995 are listed. .

It should be noted that the total number of commodities transported by rail in the l vicinity of Waterford 3 in 1995 has decreased by 114 (45.7%) with respect to the 1992 survey. However, the number of cars passing the plant has increased by 16.5%. There were increases in the shipments of chlorine and hydrogen chloride with decreases in the shipments of ammonia, trimethylamine, liquefied petroleum gas and chloroform. Additionally, there were no shipments of sulfur dioxide, gasoline, benzene, isopentane, xylene, hydrogen peroxide, trichloroethylene, and 1,1,1 trichloroethane.

j 3 The analysis of the 1996 survey results indicate the overall hazard probability (for i incapacitation of operators) from toxic chemicals being transported by rail is 4

i approximately 2.9 x 10 per year which is slightly above the 104 per year criterion j for accidents leading to radiological releases in 10CFR100. Incapacitation of the

operators will not necessarily lead to radiological releases in excess of 10CFR100 l guidelines. The plant would have to experience a reactor trip and multiple system 4

2 i

I

failures would have to occur to produce core damage. NUREG/CR-2650 suggest a value of 0.1 for the probability that incapacitation of the operators would lead to a radiological release in excess of 10CFR100 guidelines. With this factor applied, the l

probability that toxic chemicals frequently transported on this rail line could cause a 7

radiological release is 2.9 x 10 per year. This probability is well below the 104 per year criterion described in FSAR Section 2.2.3.3.

3.0 Trucks. Shio and Barae Sources )

l Data on shipments of toxic chemicals in the Waterford 3 vicinity by truck, ship and barge were obtained. There is only one highway near Waterford 3 for a spill of a i truck load of a toxic chemicals to pose a possible hazard to the Control Room. This

is Louisiana Highway 18, which is a local road and does not carry through truck l traffic. Therefore, it was assumed that only shipments to or from facilities in the i

!' immediate vicinity (i.e. those surveyed) would travel on this road. Transient source data (from U.S. Army, Corps of Engineers) was tabulated in the form of hazardous freight traffic on the Mississippi River that was shipped past river mile 129 in 1994.

This information is illustrated in Table A-4. l t

j Ship and barge chemical shipments listed in Table A-4 were found not to pose I j additional hazards. These chemicals were within the limits specified by Regulatory  !

l Guide 1.78 for stationary sources at the nearest distance of the river channel to the  ;

Waterford 3 Control Room. '

4.0 Chlorine Sources The largest chlorine sources in the Waterford 3 vicinity are the Occidental Chemical 500 ton storage tanks located one mile from the Control Room. The Waterford 3 Control Room had already been evaluated with respect to a hypothetical rupture of the nearest such tank. This evaluation was included in the report transmitted to the L NRC by letter W3P85-3154, dated January 24,1986. As stated in a prev'ious report

! there should be no need to repeat this analysis in the future unless other sources of l chlorine are reported or unless the characteristics of the Control Room or the chlorine detectors should change.

5.0 Results of Stationary and Transient Sources Analyses Over 130 sources of toxic chemicals, either storage tanks, material in process, or material in transit, were analyzed. None these sources were found to pose an i j unacceptable hazard to Waterford 3 Control Room personnel.

REPORT B RESULTS OF THE 1996 SURVEY AND ANALYSIS OF EXPLOSIVE HAZARDS IN THE VICINITY OF WATERFORD 3 INTRODUCTION Technical Specification 6.9.1.10 for Waterford 3 requires Entergy Operations, Inc.

to do "a survey of major pipelines (greater than fcur inches in diameter) within a 2-mile radius of Waterford 3, which contain explosive or flammable materials and may represent a hazard to Waterford 3, including scaled engineering drawing or maps l that shows the pipeline locations," and to submit the results to the NRC at least once every four years. This report is a discussion of the results of the 1996 survey.

HAZARDOUS PIPELINE SURVEY 1.0 Facilities i

! Three sources were used to compile a list of companies operating inter-plant j pipelines within a two mile radius of Waterford 3. One source was the result of the

, 1992 pipeline survey, which was summarized in Table 2.2-6 of the FSAR (Rev 6).

The second was Waterford 3 Licensing Document Change Request 95-0012 which

added a new Air Products and Chemicals, Inc. (Air Products) hydrogen pipeline to i the FSAR in Revision 8. The third was the St. Charles Parish Local Emergency l Planning Committee records.

i i Pipelines carrying significant quantities of hazardous materials located entirely l within the boundaries of a single facility were reported as part of the survey of j hazardous chemicals stored, processed or transported in the Waterford 3 vicinity.

I j- The Louisiana Hazardous Material Information Development, Preparedness, and i Response Act requires that reports must be submitted to the Local Emergency i Planning Committee for any material, including pipelines and maritime vessels, for

The results indicate that there are a total of 25 pipelines operating within two miles  ;

of Waterford 3 and there were 24 lines listed in the 1992 survey. Air Products added a hydrogen pipeline in the Fall of 1994. This pipeline transports hydrogen l from the Dupont Chemical, Inc. plant in Reserve to the Union Carbide Corp. plant in Taft. This 12.75 inch diameter pipeline crosses the Entergy property in the vicinity of Waterford 3. There are no above ground sections of the pipeline on Entergy '

property. The pipeline is buried to a minimum depth of five feet on the Entergy property. The closest above ground section of the pipeline is 3200 feet from the eastern boundary of the property. The estimated flow rate of hydrogen in the 7

pipeline is 3.648 x 10 scf/ day.

l A 10CFR50.59 evaluation was done to ensure that there were no unreviewed safety l questions associated with this new hydrogen pipeline operation. The FSAR (Rev.

l 8, 5/96) was also updated to describe this new pipeline.

T6e B-3 provides a tabulation of the 1996 pipeline survey results and Figure B-1 provides a map illustrating the pipeline locations.

2.0 Assessment of Explosive Hazards in the Waterford 3 Area r .

l 2.1 Pipeline Explosive Hazard l 1 The survey of pipelines within a two mile radius of Waterford 3 revealed ons new operational line, the Air Products hydrogen line described above.

Key parameters related to the explosion of the hydrogen pipeline were compared to key parameters related to the explosion of the Evangeline Natural Gas Pipeline l (FSAR Section 2.2.3.1.3.1.2), at the pig trap station, to show that the explosion '

effects associated with the new hydrogen pipeline are less severe than the explosive effects of the Evangeline Pipeline.

The key parameters that were compared are:

a. Size of the explosive cloud, based on the major semiaxis of the lean ellipsoid.

b. Distance from the center of mass of the explosive cloud to Waterford 3 safety

related structures.

i

!' c. Specific heating value of the air / gas mixture.

_ The results of the comparison indicate that;

a. The explosive cloud from the hydrogen pipeline rupture is much smaller than the cloud from the Evangeline Pipeline rupture. The lean hydrogen cloud from a pipe break is slightly more than one third the size, based on the major semiaxis, of the lean natural gas cloud from the Evangeline Pipeline break.

b. The distance from the center of mass of the hydrogen clouds to the Waterford 3 safety related structures is much greater than the distance from the center of mass of the natural gas cloud to the safety related structures.

The distance from the center of the explosion to the safety related structures for the hydrogen pipeline is slightly greater than double the distance for the Evangeline Pipeline.

c. The specific energy liberated from the stoichiometric combustion of both the hydrogen / air mixture and the natural gas / air mixture is identical.

Therefore, the consequences of the potential hydrogen pipeline break and explosion are less severe than the consequences of the break and explosion of the Evangelino Natural Gas Pipeline, at the pig trap station. The allowable overpressure, on the Waterford 3 safety related structures, is 3.0 psi (design basis).

The design basis overpressure event is the LPG tank truck explosion, on Highway 18, as presented in FSAR Section 2.2.3.1.2. The maximum overpressure from an explosion on the Evangeline Pipeline, at the pig trap statior;, is slightly less than 1.0 ;

psi. The overpressure from an explosion on the new hydrogen pipeline would be much less than 1.0 psi, as shown above. Thus, it is concluded that the potential hazard posed by a break and explosion of the new hydrogen pipeline is well wit 5in the design basis of the Waterford 3 safety related structures and is bounded by previously analyzed explosive events.  !

2.2 Explosive Hazards At Other Industrial Facilities l

No new significant sources of explosive material were found as a result of the 1996 survey of industrial facilities as compared to the 1992 survey. The 1996 survey ascertained the location of the major sources of hazardous and explosive material in the area. As a result, it has been determined that these sources are the same or in some cases reduced when compared to the previous survey. Therefore, these materials pose no more of a hazard than what was previously calculated.

Taking the 1996 findings into consideration, the most severe explosive event involving a stationary tank continues to be as discussed in the FSAR (Rev. 2). No new materials capable of posing a comparable hazard were found.
