e 2 SITE CHARACTERISTICS 2.1 Geoarachv and Democrachy The July 1981 edition of the " Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants" (SRP, NUREG-0800) includes Chapter 2, Site Characteristics. WNP-2 was reviewed in accordance with Sections 2.1.1, 2.1.2, and 2.1.3 of the SRP.
The results of this review are summarized below.
2.1.1 Site Location WNP-2 is located in the southeast area of the U.S. Department of Energy's (00E)
Hanford Site in Benton County, Washington, The site is approximately 5 kilometers (3 miles) west of the Columbia River at River Mile 352, approximately 19 kilometers (12 miles) northwest of Richland, 29 kilometers (18 miles) northwest of Pasco and 34 kilomete} (21 miles) northwest of Kennewick.
Figure 2.1.1 shows the general region of the WNP-2 site.
Si u.shd 4
The site isgnear the middle of the relatively flat, essentially featureless plain,namely a shrub steppe with sage brush interspersed with perennial native and introduced annual grasses extending in a northerly, westerly and southerly direction for several miles.
The plain is characterized by slight topographic relief with a maximul rade across the plant site of approximately ten feet.
A The reactor is located at 46*28'18" north latidue and 119 19'58" west longitude.
The approximate Universal Transverse Mercator coordinates are 5,148,840 meters north and 320,930 meters east.
2.1.2 Exclusion Area Authority and Control The applicant has defined the exclusion area as a circle with its center at the reacter and a radius of 1950 meters (6400 feet) (see Figure 2.1.2).
There are no residents within the exclusion area., Industrial facilities located in the site area are the H.J. Ashe Sub tation and the WNP Units 1 and 4.
A highway and a railroad traverse the ex sion area.
Other than these facilities there are no activities unrelated to he operation of WNP-2 within the exclusion Both WNP-1 and 4 and their respective access roads will be owned, area.
operated and controlled by WPPSS.
The exclusion area extends beyond the plant property.
All exclusion area land outside the plant property is owned by the United States and is managed by the U.S. Department of Energy (DOE) as part of the Hanford Site.
The applicant has obtained a long-term lease from DOE over this area which gives it the authority, required by Part 100, to determine all activities in this exclusion area.
In case of emergency, the applicant has made arrangements with Federal and State authorities to control traffic on the routes traversing the exclusion area, incluoing possible removal of personnel at the Ashe Substation.
We concluoe, by virtue of lease agreement with the United States government, that the applicant nas the authority to determine all activities witnin tne exclusion area, as recuired by 10 CFR 100.
2.1. 3 Pooulaticn Distribution The resioent population in the vicinity of the WNP-2 site is shown below as a function of time and radial distance.

290 4147 The nearest community with a population of.more than 1,000 persons is the City of Richland, Washington (1980 estimated population of 33,512) located about 19 ki.lometers (12 miles) SSE of the tite.
The nearest significant transient population is located at 00E area 400 (HE0L) located about 3 to 4 miles SW of the piant.
The employment level at arca 400 is currently 1187.
The applicant has chosen a low population zone (LPZ) radius of A.8 kilomsters (3 miles).
As noted above, the current and projected (througn 2030) resicential population within the LPZ is zero.
The applicant has indicated that the nearest densely pcpulated center, as defined in 10 CFR 100, of about 25,000 or mere persons, is also the City of Richland, Washington. The population center distance is at least one and one third times the LPZ radius of 4.8 kilometers (3 miles), as required by 10 CFR 100.
We made an independent estimate of the 1970 population within an 80 kilometers (50 miles) radius.
Our estimate, 200,300 persons, agreed reasonably well sith the applicant's value of 251,684. The applicant projects that this population will increase to a value of abcut 383,828 by the year 2030. This represents a growth rate of about 8.8% per decade for the period from 1980 to 2030.
The staff has calculated a 10% per decade growth rate using the Bureau of Economic Analysis (BEA) prcjections for those BEA areas within an 8h kilometers (50 miles) radius of the WNP-2 site resulting in an estimated population in the year 2030 of 322,585 persons.
Thus, the staff and applicant estimates agree reasonably for the year 2030 as well.
2.1.4 Conclusions On the basis of (1) the 10 CFR 100 definitions of tne exclusion area, (2) the low population zone and the population center distance, (3) cur analysis of the onsite meteorological data from which the relative concentration factors (x/Q) were calculated (see Section 2.3 of this report), and (4) tne calculated potential radiological dose consequences of design basis accidents (see Section 15.0 of this report), we have concluded that the exclusion area, low 03/05/82 2-4 WNP 2 SER SEC 2
population zone and population center distance meet the criteria of 10 CFR 100 and are acceptable.
2.2 Nearby Industrial, Transoortation, and Military Facilities The Washington Puolic Power Supply System Unit 2 was reviewed in accordance with Sections 2.2.1, 2.2.2, 2.2.3, 3.5.1.5, and 3.5.1.6 of the SRP NUREG-0800, July 1981.
The results of this review are summarized below.
2.2.1 Transoortation Routes The WMP-2 site is serviced by a new two-lane paved access road connected to the DOE road system.
State Highway 240 traverses the Hanford Reservation from tne southeast to the northwest.
Highway 240 passes within about 11 kilometers (7 miles) of WNP-2 in the southwest u rant.
To the southeast it goes to Richland, Washington.
To the north it meets State Highway 24, which goes west to Yakima, Wasnington and north across the Vernita bridge on the Columbia River 37 kilcmeters (23 miles) (see Figure 2.2.1).
The existing mainline railroad track (which is owned and operated by the DOE in suoport of the Hanford Operations), and the railroad spurs to WNP-2, WNP-1 and 4, and to FFTF all run within the exclusion area of the WNP-2 site (Figures 2.1.2, 2.2.2).
During 1978 the following number of railroad cars of potentially 34 dangerous materials were transported past the site via the mainline track:
cars of caustic soca, 2 of chelating compound, 3 of chlorine, 30 of helium,1 of hydroacetic acid, 53 racioactive material and 7 cf sulfuric acid.
Discus-sions with DOE confirmed that the above type and frequency of shipments are typical with no anticipated changes.
The DOE, Richland Operations Office has agreed to notify WPFSS prior to trans-porting any e> plosive shipments of more than 1,800 pounds (a detonation of which will yield an overpressure equal to 1 psi at the nearest safety-related equipment) past the WNP-2 site.
There have been no sucn shipmen in the past 10 years.
They will hi3o inform WPPSS of any plans to regularly hip explosives of a lesser quantity by rail past the site. WPPSS will, prior to the start of shipping of explosives, provide an analysis to the NRC to demonstrate that the With potential safety conse4uences from such shipments are acceptably small.
this agreement, we find that the railroad will pose no undue hazard to the safe operations of WNP-2.
The makeup water inlet structures are located in the Columbia River 315 feet l
from the shoreline at low riverflow (36,000 cfs; El. 341.73 ft) at river mile (RM) 351.75.
A significant amount of Columbia River barge traffic moves as far uostream as tre Ports of Pasco and Kennewick.
Also, a docking facility estao-lished by the Port of Senton in North Richland (8 miles downstream of the WNP-2 site) is accessible by carges witn a maximum 16 feet of draft (normally 2500 to 3000 tons).
Tne first use of tnis facility was in April 1973 when the FFTF reactor vessel was officaded.
Traffic to the Port of Benton's North Ricnlana Dock is very infrequent in comparison to that in the brts cf Pasco and Kennewick due to the lack of large industrial concerns in the region between Richland and upstream Priest Raoics Dam. On several occasions in the past, lightly loadec barges have transported material to the vicinity of the Hanford Reservation.
This requirec ava;1acility of an adecuate flow from Priest Rapids Dam during i
2-5 WNP 2 5ER SEC 2 1
03/05/82
the transit period.
At present no barge traffic moves past the WNP-2 water intake structure nor is any anticipated.
On the basis of the separation distances involved, the nature of the materials transported and tne plant design characteristics, we conclude that traffic along these transportation routes will not adversely affect the safe operation of WNP-2.
2.2.2 Nearby Facilities There are no military bases, missile sites, manufacturing plants, cnemical plants, chemical storage facilities or airports within a 8 kilometers (5 mile) radius of the site.
Acccrding to the Richland Operations Office of the DOE, there are no plans for storage facilities, airports, oil and gas pipelines, or tank farms on the Hanford Reservation.
There are, however, the H.J. Ashe Substation, the DOE's Fast Flux Test Facility (FFTF), the WNP-1 and 4 construction sites, the radio-t M ":00 L t.. a;t; S 1 += and a M
active waste Wye Burial Ground'wititili i 8 Eilomete7s "(53il'esI raalus of the

permanent meteorological tower WNP-2 site.
Airports, low level Federal airways, and airport instrument approaches in the vicinity of the WNP-2 are shown in Figure 2.2.3.
Federal airway V4N is located over WNP-2 with a minimum enroute altitude of 3500 feet above mean sea level (MSL).
Traffic acproaching Pasco on airways V238, V298N, or V4N may be routed onto an arc 14 nautical miles from the Tri-Cities Airport.
As shown on Figure 2.2.3, this arc, which hak a minimum altitude of 300[ feet MSL, passes within a
=
few miles of WNP-2.
Also two instrument approach procedures for the Richland Airport permit maneuvering, as part of the initial approach segments, within an area that includes the WNP-2 at a minimum altitude of 2100 f2et MSL.
The Richland airport is 19 kilometers 12 miles) south of the plant, and the Tri-Cities Airport in Pasco is 29 kilometers (18 miles) southeast. Vista Field in Kennewick is located 31 kilometers (19 miles) south southeast and is used almost exclusively by small, private aircraft.
In addition to these airports there are two privately owned airstrips, McWhorter and Hatthaway Ranch, located 32 kilometers (20 miles) southwest and 21 kilometers (13 miles) northeast, respectively. A DOE irstrip 23 kilometers (14 miles) northwest of WNP-2 has been closed since Ma 1976.
Military aircraft activity is limited to periodic use of part of the airspace over the Hanford Reservation as a marshalling area for aircraft participating in training missions on the Yakima Firing Center located between 30 and 50 miles northwest of WNP-2.
Such operations are typically scheduled at two to three year intervals and may include six, aircraft per day for eight days of exercises.
All flights would be more than 1000 feet above ground level and all cperations would be conducted uMer Visual Flight Rule (VFit) conditions.
An explosives and ordnance test-site coerated by Battelle-Northwest Laboratories approximai.ely 21 kilcmeters (13 miles) northwest of the site was abandoned in mic-1975.
Exolosives for operations such as quarrying or seismic stucies on the Hanford 9eservation are brought to the blasting site as needed and unused quantities are removed immediately.
The only explosives stored on tne Hanforc 03/05/82 2-3 WNP 2 SER SEC 2
l Reservation are small arm 3 ammunition for use by the reservation security oatrol.
There are no explosives or munitions storec within five miles of the wNP-2 site. A small arms firing range used for training by the security patrol is located 13 kilometers (8 miles) due south of the olant.
The H.J. Ashe Substation is located approximately 0.8 kilometers (1/2 mile) north of WNP-2 and is operated by the Bonneville Power Authcrity as part of its electrical transmission system.
t Within the exclusion area radius,a6 two icentical 1250 MMe PWR nuclear power plants (WNP-1 and WNP-4)3 have been ur. der construction for WPPSS. The projected fuel load date for WNP-2 project is December 1984. WNP-4 has been cancelled.
Transport of all materials and men to anc from WNP 1, 4 will continue / to be regulated by WPPSS.
These projects have their own access road wnich ties inte Route 4, 2.6 kilometers (1.6 miles) south of the WNP-2 access read tie.
It is not anticipated that activities at WNP 1, 4 will interfere with the safe operation WNP.2.
The Fast Flux Test Facility is located about 4.8 kilometers (3 r.iles) southwest of the WNP-2 site.
FFTF contains a sodium cooled fast flux test reactor'used for testing reactor fuel elements. The NRC staff has conductec a safety review of this facility and concluded that it presents no undue risk to public health and safety beyonc its site boundary consistent with the safety considerations for light water reactors (see NUREG-0358 Suppl. 1, May 1979 for further details).
Immediately due west of tne WNP-2 site is the Wye Burial Ground.
Another waste disposal site, 300 North, is located about 5.6 kilometers (3.5 miles) south of WNP-2.
1 The nearest petroleum product storage tanks are located 35 kilometers (22 miles) southeast cf WNP-2.
These consist of 13.5 million gallons at the marine terminal at Big Pasco, 25 million gallons at the Chevron Pipeline Cocpany, and 23 million gallons at the Tidewater Barge Line. There are no oil or gas pipelines in the vicinity of WNP-2.
The nearest major natural gas pipeline to the WNP-2 site is about 19 kilometers (12 miles) away.
This distance eliminates any potential hazard to plant operations cue to a natural gas fire or explosibn.
2.2.3 Conclusions Our review has been conducted based upcn the criteria given in 10 CFR 50, Appendix A, General Design Criterion 4 and in Standard Review Plan Section 2.2.3.
I We conclude that the plant is adeouately protected from and can be operated with an acceptable degree of safety as a result of the activities at nearoy transportation, industrial and military facilities.
2.3 Meteorolocy The meteorology sections are presentea on the basis cf material presentec in the FSAR, review of generally accepted scurces of data and re+erence material, ano the use of guidance in the NRC Regulatory Guices cited.
The individual sections are in accordance with those appropriate Stancarc Review Plan
'(NUREG-0800) sections.
