NUCLEAR REGULATORY COMMISSION
[Docket No. 50-362]
Southern California Edison Company; San Onofre Nuclear Generating
Station, Unit 3, Environmental Assessment and Finding of No Significant
Impact
The U.S. Nuclear Regulatory Commission (NRC) is considering
issuance of an exemption from Title 10 of the Code of Federal
Regulations (10 CFR) Part 74, Section 74.19(c), for Facility Operating
License No. NPF-15, issued to Southern California Edison Company (SCE,
the licensee), for operation of the San Onofre Nuclear Generating
Station (SONGS), Unit 3, located in San Diego County, California.
Therefore, as required by 10 CFR 51.21, the NRC is issuing this
environmental assessment and finding of no significant impact.
Environmental Assessment
Identification of the Proposed Action:
The regulation 10 CFR 74.19(c) states, ``Other than licensees
subject to Sections 74.31, 74.33, 74.41, or 74.51, each licensee who is
authorized to possess special nuclear material, at any one time and
site location, in a quantity greater than 350 grams of contained
uranium-235, uranium-233, or plutonium, or any combination thereof,
shall conduct a physical inventory of all special nuclear material in
its possession under license at intervals not to exceed 12 months.''
By application dated January 14, 2008, the licensee requested an
exemption from certain recordkeeping requirements in Section 74.19(c)
for SONGS Unit 3. The exemption would allow SCE to deviate from the
physical inventory requirements for 12 irradiated fission chambers
removed from SONGS 3 in 1995 and in storage at the plant.
The Need for the Proposed Action:
The proposed action would allow the licensee to not have to perform
physical inventory of the 12 irradiated fission chambers that are
stored in the plant.
The licensee pointed out that the as low as is reasonably
achievable (ALARA) requirement in 10 CFR Part 20, ``Standards for
protection against radiation,'' requires ``* * * making every
reasonable effort to maintain exposures to radiation as far below the
dose limits in this part as is practical consistent with the purpose
for which the licensed activity is undertaken, * * *.'' This request
for an exemption from the physical inventory requirements of 10 CFR
74.19(c) would relieve SCE of significant and unnecessary personnel
exposures with no decrease in quality and safety.
Environmental Impacts of the Proposed Action:
NRC completed its safety evaluation of the proposed action and
concludes that the exempting the licensee from performing a physical
inventory of the 12 irradiated fission chambers in the plant is
acceptable.
The details of the staff's safety evaluation will be provided in
the exemption that will be issued as part of the letter to the licensee
approving the exemption to the regulation.
The proposed action will not significantly increase the probability
or consequences of accidents. No changes are being made in the types of
effluents that may be released off site. There is no significant
increase in the amount of any effluent released off site. There is no
[[Page 79937]]
significant increase in occupational or public radiation exposure.
Therefore, there are no significant radiological environmental impacts
associated with the proposed action.
With regard to potential non-radiological impacts, the proposed
action does not have a potential to affect any historic sites. It does
not affect non-radiological plant effluents and has no other
environmental impact. Therefore, there are no significant non-
radiological environmental impacts associated with the proposed action.
Accordingly, the NRC concludes that there are no significant
environmental impacts associated with the proposed action.
Environmental Impacts of the Alternatives to the Proposed Action:
As an alternative to the proposed action, the staff considered
denial of the proposed action (i.e., the ``no-action'' alternative).
Denial of the application would result in no change in current
environmental impacts. The environmental impacts of the proposed action
and the alternative action are similar.
Alternative Use of Resources:
The action does not involve the use of any different resources than
those previously considered in the Final Environmental Statement for
the SONGS Units 2 and 3 dated May 12, 1981.
Agencies and Persons Consulted:
In accordance with its stated policy, on October 22, 2008, the
staff consulted with the California State official, Roger Lupo of the
Radiologic Health Branch of the California Department of Public Health,
regarding the environmental impact of the proposed action. The State
official had no comments.
Finding of No Significant Impact
On the basis of the environmental assessment, the NRC concludes
that the proposed action will not have a significant effect on the
quality of the human environment. Accordingly, the NRC has determined
not to prepare an environmental impact statement for the proposed
action.
The licensee requested that the application be withheld from public
disclosure, in accordance with 10 CFR 2.390, because it contained
sensitive security-related information. The NRC staff agrees that the
licensee's application dated January 14, 2008, contains security-
related information and should be withheld in its entirety. Therefore,
no further details with respect to the proposed action are publicly
available.
Dated at Rockville, Maryland, this 18th day of December 2008.
