RE:
CON~PLETIOt4 OF SEP TOPIC I1-1.B Your letter dated flay 4, 1979, indicated that you have examined our draft evaluation of the subject topic dated January 30, 1979.
You suggested editorial or corrective changes to the assessment to make it more accurately reflect your facility design. We have incorporated your suggested modifi cations in the enclosed assessment. With these modifications our review of SEP Topic 11-1.B is coiuplete and will be a basic input to the integrated assessinent of your facility.
The subject assessment compares your facility design with the criteria currently used by the staff in licensing new facilities. This assessment miay need to be re-examined if you modify your facility or if the criteria are changed before we complete our integrated assessment.

November 7, 1979 SAN ONOFRE UNIT 1 Topic II-1.B -
Population Distribution The safety objective of this topic is to assure that the low population zone and population center distance specified for the site are compatible with the current population distribution and are in conformance with the guidance of 10 CFR Part 100.
Information on the population distribution in the region surrounding the San Onofre Nuclear Generating Station has been updated several times since the issuance of a construction permit for Unit 1 primarily as part of the licensee's application to construct and operate Units 2 and 3.
The most current estimates of the population of the San Onofre tite are:.
contained in the Units 2 and 3 FSAR(1 ): Both the low population zone and population center distances have been revised during the construction permit licensing activities for Units 2 and 3.
The low population zone for the San Onofre site, which is the same for Units 1, 2 and 3, is specified to be the area within a distance of 1.95 miles measured from Units 2 and 3, as shown in Figure 2.1-12 of the Units 2 and 3 FSAR. The distance to the outer boundary of the low population zone measured from the center of the Unit 1 containment is about 1.8 miles.
The low population zone is contained entirely within the boundaries of Camp Pendleton. The residential population in the low population zone was estimated to be about 1,130 in 1976 and is expected to increase to about 1,200 by 1980 and to remain at about that level over the lifetime of the plant.

-2 The City of San Clemente has been designated as the nearest population center, as defined in 10 CFR Part 100. San Clemente had an estimated population of approximately 25,000 in 1978. The distance from Unit 1 to the nearest corporate boundary of San Clemente is approximately 2.5 miles. The distance to the nearest residence within the city limits is currently about 2.7 miles.
The presence of the military reservations which lie between the city boundary and the site eliminates the potential for future residential growth toward the San Onofre site. The population center distance of 2.5 miles for Unit 1 is greater than one and one-third times the low population zone distance of 1.8 miles, as required by 10 CFR Part 100.
The changes in the population distribution in the vicinity of the San Onofre Nuclear Power Station have been well documented as the result of the licensing activities on Units 2 and 3, and we conclude that the population center distance and low population zone for Unit 1 have been properly revised so that Unit 1 is in conformance with the distance require ments of 10 CFR Part 100. This completes the evaluation of this SEP topic.
Since the plant design conforms to current licensing criteria, no additional SEP review is required.
