l l SIGNIFICiNT HAZARDS CONSIDERATION Commonwealth Edison has evaluated the proposed Technical Specification Amendment and determined that it does not represent a significant hazards consideration. Based on the criteria for defining a significant hazards consideration established in 10 CFR 50.92, operation of LaSalle County Station Units 1 and 2 in accordance with the proposed amendment will not:
- 1) Involve a significant increase in the probability or consequences of an accident previously evaluated because: the chlorine detectors are not used in the analysis mitigation or detection of any accident analyzed in Chapter 15 accident analysis.
- 2) Create the possibility of a new or different kind of accident from any accident previously evaluated because: chlorine gas does not contribute to or cause or change any type of accident for which an analysis is provided in Chapter 15.
- 3) Involve a significant reduction in the margin of safety because: the protection was originally installed beyond requirements. The HVAC system still has the ammonia detection and automatic transfer ability as well as manual transfer to the recirculation mode.
The likelihood of any chlorine release in the vicinity of LaSalle County Station is negligible and the likelihood of any release reaching the control room ventilation is also considered negligible as no known bulk shipments or storage of chlorine exists within a 5 mile radius of LaSalle Station. In addition, the citing of LaSalle is favorable in that prevailing winds would tend to carry any toxic gas away from the plant, the Illinois River is greater than 4 miles from the plant and 200 feet lower in elevation.
Based on the preceding discussion, it is concluded that the proposed system change clearly falls within all acceptable criteria with respect to the system reaching component, the consequences of previously evaluated accidents will not be increased and the margin of safety will not be decreased.
Therefore, based on the guidance provided in the Federal Register and the criteria established in 10 CFR 50.92(c), the proposed chango does not constitute a significant hazards consideration.

..~ ATTACHMENT D SURVEV OF CIILOPINE FIIIPMFNT IN Tile VICINITY OF LASALLE_ COUNTY STATION Introduction The licensing of the LaSalle County Station required a survey of industries and transportation routes in the site vicinity, which may use, store and/or transport hazardous chemicals.
This information was then used to evaluate the control room habitability at the LaSalle County Station. One such survey, conducted in 1975, revealed that anydrous ammonia and probably chlorine were transported by barge on the Illinois River. The information gathered during this survey was not ccmplete enough to conclude that chlorine was not shipped in larue quantities by barge on the Illinois River.
A new survey was conducted in January-February 1986 to supplement the information obtained from the 1975 survey. The purpose of the new survey was to determine if chlorine is a hazard to the control room habitability. The following discussion describes the Regulatory Guides which form the basis of the control room habitability evaluation, the results of the two surveys and the conclusion regarding chlorine as a hazard. Based on the infor-mation collected to date, it is concluded that no special protection provisions are required for chlorine at the LaSalle County Station.
Regulatory Guides ,
Regulatory Guide 1.78, " Assumption for Evaluating the liabitability of a Nuclear Power Plant Contrcl Room During a Postulated IIazardoun Chemical Release" identifies chlorine as a hazardous chemical and requires a control room habitability analysis in case there is an accidental chlorine release from stationary or mobile sources near the plant. Regulatory Guide 1.95, " Protection of Nuclear Power Plant Control Roon Operators Against an Accidental Chlorine Release" specifically addresaes onsite accidental chlorine release. Ilowe ve r , it can also be used in analyzino effects of an offsite chlorine release.
Regulatory Position 1 of Regulatory Guide 1.78 states that chlorine stored or situated at distances greater than five miles from the control room would not be conaidered in evaluating habitability of the nuclear power riant control roon during a postulated chlorine release. Regulatory Guide 1.78 alno specifies frequency, distance, and quantit*/
of chemicals transported or stored with respect to the control room that require a control room habitability analysis. The 1
1 i
l Regulatory Guide also specifies three modes of transportation of chlorine manufactured, stored or used by the industries
! in the vicinity of the control room: railroads, highways, j and waterways.
l 1975 Survey of Chlorine _ Shipment The LaSalle Final Safety Analysis Report (FSAR) Section 2.1.1 describes the location of the plant site and the transpor-tation routes near the site. The FSAR Section 2.2.2 describes the nearby industrial, transportation, and military facilities.
All indu$ trial facilities are located outside of a five mile radius of the plant; therefore, chlorine used or stored at
- these facilities need not be considered in evaluating control l room habitability. A survey of these industries was conducted l in 1975 to determine the shipment of chlorine by the three l modes of transportation. U.S. liighway 6 and State IIighway 47, l the nearest highways'to the station used by these industries l and the Chicago Rock Island and Pacific, the nearest railroad,
[ are all located fartl'er than five miles from the station.
l Therefore, transportation of chlorine by these two modes of transportation need not be considered in the control room habitability analysis.
[ The FSAR Section 2.2.2.4 describes the rive.r traffic on the Illinois River passing the site. Section 2.2.3.1.C concluded that the only transportation route carrying chlorine within five miles of the station is the Illinois River, which is located approximately 4.7 miles north of the station. A review of the 1974 data on commodities transported on the Illinois River (FSAR Table 2.2-4) did not differentiate barge shipments of chlorine from other chemicals. In addition, the survey also revealed that although small quantities of chlorine were being used by the Illinois Nitrogen Corporation located at river mile 248.7, approximately five miles north of the station, sufficient information was not available to determine that it was not receiving its chlorine supply by barges. Therefore, in order to expedite the licensing process, chlorine detectors were provided in the control room ilVAC system intake air ducts.
1986 Survey of Chlorine Shipments !
To supplement the 1975 survey and to obtain additional specific information on chlorine shipment, a survey was conducted during January-February 1986 to determine if chlorine is still transported in barges on the Illinois River.
For this survey, information was obtained from the Chlorine Institute, a national trade organization with headquarters in 2
l L----_--__-.-.
., +
e
.l t
New York, whose members are mostly chlorine producers. The
~
Institute carries out research, produces literature, and in general, maintains the most up-to-date information on chlorine in the United States. ,
In 1975, the Institute supplied a list of the active chlorine 1 barge operators in the United States (Reference 1) . As a 4
part of the January 1986 survey, all the barge operators
, that travel on inland waterways, were contacted. The 1975 i list was used (Exhibit 1) , since the Chlorine Institute j stated that no new chlorine barges have been built in the ,
i U.S. in 16 years. All, but one, of the barge operators stated that they do not operate on the Illinois River. One operator, E. I. du Pont refused to provide any information on the whereabouts of its chlorine barges. Despite the lack of
- information from the one barge operator, information from other_
barge operators and agencies indicates that no chlorine barges operate on the Illinois River.
l In addition to the Chlorine Institute, the following govern-ment agencies were also contacted for information on the j shipment of chlorine on the Illinois River:
l The U.S. Coast Guard, Washington, D.C.;
The U.S. Army Corps of Engineers, Rock Island, Illinois (for the Lockmaster at Dresden); and The Lockmaster at Marseilles Lock and Dam.
i These agencies regulate, or are responsible for gathering ,
, data on the transportation of chemicals on inland waterways.
To determine if chlorine would be transported in barges other than chlorine barges, the U.S. Coast Guard in Washington, D.C.
(Reference 2) was contacted. The Coast Guard stated that the U.S. Department of Transportation does not prohibit
~
chlorine from being transported along with other cargo on other types of barges, other than chlorine barges. Iloweve r ,
according to the U.S. Coast Guard , since chlorine in bulk quantity is transported by barge only, if there are no 1 producers or bulk users of chlorine along the Illinois River, it would be highly unlikely that chlorine is being shipped t on the river. Small industrial users of chlorine are not likely to transport chiarine by barge. The 1986 survey also indicated that a previously identified small industrial user, Illinois Nitrogen Corp. (See FSAR Table 2.2-3), is not listed j anymore in the 1985 Illinois Manufacturers Directory (Befer-
! ence 3). Illinois Nitrogen Corporation's facilities were purchased by Kaiser Aluminum and Chemical Company in 1981.
Kaiser does not receive, ship, store, or une chlorine at thlu ;
site (Reference 4) . In addition, there were two dock and l 3 i
I
I 4 h l
l anchorage facilities (Seneca Port District and Conti-Carriers &
Terminals) identified on the Illinois River within five miles of the LaSalle site. However, these do not receive, ship, store, or use chlorine (Reference 5 and 6).
Since the Chlorine Institute keeps records of chlorine activi-l tres, they were contacted to determine if there are any chlorine l producers or bulk users along the Illinois River. The Chlorine Institute is not aware of any chlorine producers in Illinois, or any bulk users along the Illinois River (Reference 7) .
i In addition, the lockmasters at both the Dresden and Marseilles l
locks indicated that in the years they have been working at the locks (approximately 16 to 20 years), neither of them
.has ever seen a chlorine barge on the Illinois River (Refer-ence 8 and 9).
l Conclusion l The habitability of the LaSalle Units 1 & 2 control room was i evaluated using the procedures described in Regulatory Guides 1.78 and 1.95. As indicated by the 1986 survey, no l offsite storage or use of chlorine occurs at any industry or l is transported on any routes (highway, waterway, or railroad) within five miles of the control room. There is no onsite storage of chlorine; sodium hypochlorite biocide system is used, thus eliminating an onsite chlorine hazard. In accordance l with plant emergency plans and procedures, self-containing i breathing apparatus is provided for assurance of control room habitability in the event of occurrences such as smoke hazards, naced on the 1986 survey, it in our conclusion that chlorine is not shipped in bulk quantities by highway, railroad or river near the LaSalle County Station. We, therefore, conclude that chlorine detectors are not required for the LaSalle County
! Station.
