Truck crew size was assumed to be 2 persons. Crew risk is for the time spent driving approximately 161 km (100 miles) in the Las Vegas area; the risk involved in driving to thegas Vegas area is not included.

The incident free risk to the public does not include the risk to the crew.

The highest estimated risk to the crews is 0.2324 LRFC. This already-small risk is spread over the 40- to 60-year period during which SNF will be transported to the repository. On an annual basis, the crew risk averages about 0.0039 LRFC per year of SNF transport as a result of radiation exposures. This risk is spread among all the truck crew members, so the risk to any one driver is extremely small.

one, with or without license renewal. For comparison, about 25 percent of the Las Vegas population is expected to develop a fatal cancer from causes unrelated to SNF transport. The estimates produced by this analysis do not appreciably change the cumulative dose estimates in Table S-4.

Nonradiological truck-vehicle accidents are possible as a result of transporting SNF through Las Vegas. The probability of a fatality is estimated to be less than 0.04 under all scenarios. For license renewal, the combined radiological and nonradiological risk to the public is estimated to be between about 0.10 and 0.22 fatalities over the course of SNF transport through Las Vegas, including incident-free and accident risks. Without license renewal, the combined probability of a fatality is estimated to be between about 0.07 and 0.15.-

The above analysis shows that even with conservative assumptions, the cumulative radiological and accident risks of SNF transport in the vicinity of Las Vegas are within regulatory limits and small, it also shows that there are opportunities to further reduce human health impacts.

Transporting SNF by rail rather than by truck would reduce human health effects by reducing the number of shipments and the likelihood of accidents. Shipping SNF via the proposed beltway would reduce health impacts compared to shipping via the current interstate highway system.

The contribution to impacts of transportation of higher enrichment and higher burnup fuel need be assessed only when the fuel to be used during the license renewal term is enriched to greater than 5 percent uranium-235 or average burnup for the peak rod will be greater than currently approved by the NRC up to 62,000 mwd /MTU. If the applicant anticipates exceeding these values for enrichment or burnup during the renewal term and has received or applied for a license amendment for the values anticipated and an environmental assessment has been prepared by the NRC, which considers transportation of that fuel to and from the reactor, then that environmental assessment may be cited in the renewal application and no further information is required.

The Proposed Las Vegas Beltway

. Population density estimates for the transport routes were based on 1990 This section contains background Census data. The staff assumed that information on the proposed Las Vegas population growth of the Las Vegas area beltway including a schematic shown in would occur primarily by expansion of Figure A.1. Information in this section urban and suburban areas, rather than was obtained from the Clark County increasing population densities. For the Department of Public Works World Wide beltway route, population densities were Web page (Clark County 1997). The assumed to be similar to those of other planned beltway will eventually consist of i

urban and suburban areas of Las Vegas three connected segments including a to account for population growth induced southem, westem, and northem route by development of the beltway, which together will create a freeway " ring" around the Las Vegas Valley to take vehicles around, rather than through, the congested urban core.

The southem segment of the beltway is being built in sections, with each segment opening to traffic upon completion. The first phase of the project, from l-15 to McCarran Airport (Airport Connector),

was opened in 1994. Work on the second section, from Warm Springs Road to Windmill Lane, opened to traffic in Oct.

1995. In Feb.1997, the third portion of the project-from Windmill Lane to Eastem Ave.-became fully operational.

The fourth section of the southem beltway, Eastem Ave to Pecos Road, was completed in 1997.

The proposed northem and western i

beltway may ultimately be a 10-tane facility (a combination of mixed use and i

high-occupancy vehicle lanes) with adequate right-of-way to permit construction of a fixed guideway facility.

This is called the " ultimate facility" and will require a right-of-way width of 107 to 137 m [350 to 450 ft], plus land for interchanges or access to other transportation facilities. The planning horizon used for this transportation facility

SUBJECT:

" CHANGES TO REQUIREMENTS FOR ENVIRONMENTAL REVIEW FOR RENEWAL OF NUCLEAR POWER PLANT OPERATING LICENSES (10 CFR PART 51)"

The Commission has approved for publication in the Federal Register the proposed amendments to 10 CFR Part 51 and the Notice of Availability of NUREG-1437, Addendum i subject to the attached editonal corrections and clarifications.

1.

The proposed rule states, in part:

(M) The environmentalimpacts preserited in Summary Table S-4 of 51.52 may be I

adopted in individual power plant license renewal reviews as long as the candidate site at Yucca Mountain is under consideration for licensing..

l This could be interpreted that if additional sites are considered in the future, licensees can adopt l

[

the environmentalimpacts presented in S-4, as long as Yucca Mountain is under consideration.

l The staff should reword the proposed rule to ensure it is clear that a review, similar to that for Yucca Mountain, would need to be performed for any future site (s) under consideration. In addition, this issue should be clarified in the Background and Discussion sections of the Federal Register notices.

In addition, the quoted sentence in subsection (M) would appear to preclude reliance oa any of the environmentalimpacts presented in Table S-4 if Yucca Mountain is no longer unoer consideration for licensing. That obviously is not the intent of this Subsection. 'ne first sentence in Subsection (M) should be replaced with the following:

The environmentalimpacts presented in Table S-4 ofsection 51.52 may be adopted in individual nuclear power plant renewal reviews. In addition, the cumulative impacts of shipments to a single repository must be addressed. To do so, the conclusions regarding the cumulative impacts of transporting high-level waste to a single repository in Appendix B to subpart A of this part may be adopted as long as Yucca Mountain is under consideration for licensing.
