Proposed Revision to Probabilistic Risk Assessment and Severe Accident Evaluation for New Reactors, 66649-66650 [2012-27073]

Download as PDF Federal Register / Vol. 77, No. 215 / Tuesday, November 6, 2012 / Notices the environmental impact is that the licensed radioactive waste contractor could recycle the mercury, resulting in the same environmental impact as granting the license amendment or properly dispose of the mercury by using a Subtitle C landfill. According to the ‘‘Mercury Emissions from the Disposal of Fluorescent Lamps’’, report (https://www.epa.gov/wastes/hazard/ wastetypes/universal/merc-emi/mercpgs/emmrpt.pdf) dated March 1998, the estimated emissions from lamps being sent to a Subtitle C landfill is 100% elemental mercury and 0% for divalent mercury. The resulting mercury discharge for up to 200 lamps from the licensee would be a maximum of 20,000 milligrams elemental mercury or ten times the amount discharged in recycling the lamps. Thus environmental impacts of either method are small, denying the amendment request would result in similar environmental impacts. The environmental impacts of the proposed action as compared to the alternative action are similar and therefore, the alternative action is accordingly not further considered. erowe on DSK2VPTVN1PROD with Conclusion The NRC staff has concluded that the proposed action is consistent with NRC regulations and guidance. The NRC staff reviewed the dose modeling analysis performed in the referenced report, which considers recycling activities for much larger quantities of lamps containing Kr-85. The report, which used extremely conservative parameter values in its assessment, calculates doses to workers involved in the recycling of these lamps as well as members of the public residing near the recycling centers that are significantly less than the NRC’s corresponding annual dose limits. Since the quantity of lamps and the corresponding exposure times for workers recycling lamps from the Licensee are much smaller than those considered in the report the NRC staff is confident that the resulting doses to workers and the general public would also be proportionally smaller. Approving the proposed action would allow the Licensee to ship the lamps to a recycler for proper recycling of any of the recoverable mercury ensuring that the mercury is recycled. Recycling has shown to be the best method to recover elemental mercury which is the mercury contained in the Licensee’s lamps. Because the proposed action will not significantly impact the quality of the human environment and will allow mercury that is recoverable to be recycled and not disposed, the NRC staff VerDate Mar<15>2010 15:06 Nov 05, 2012 Jkt 229001 concludes that the proposed action is the preferred alternative. Agencies and Persons Consulted The NRC provided a draft of this Environmental Assessment to the State of Connecticut for review on April 25, 2012. On June 4, 2012, Connecticut Department of Energy and Environmental Protection responded by electronic mail. The State agreed with the conclusions of the EA, and otherwise had no comments. The NRC staff has determined that the proposed action is of a procedural nature, and will not affect listed species or critical habitat. Therefore, no further consultation is required under Section 7 of the Endangered Species Act. The NRC staff has also determined that the proposed action is not the type of activity that has the potential to cause effects on historic properties. Therefore, no further consultation is required under Section 106 of the National Historic Preservation Act. III. Finding of No Significant Impact The NRC staff has prepared this EA in support of the proposed action. On the basis of this EA, the NRC finds that there are no significant environmental impacts from the proposed action, and that preparation of an environmental impact statement is not warranted. Accordingly, the NRC has determined that a Finding of No Significant Impact is appropriate. IV.

II. Further Information

    The Office of New Reactors and the Office of Nuclear Reactor 
Regulation are revising SRP Section 19.0, which updates Revision 2 
(ADAMS Accession No. ML071700652) dated June 2007, to reflect the 
changes as listed in the description of changes. These changes include 
(1) incorporation of guidance previously contained in Interim Staff 
Guidance (ISG), DC/COL-ISG-003 (ADAMS Accession No. ML081430087) 
concerning the review of probabilistic risk assessment (PRA) 
information and severe accident assessments for new reactors submitted 
to support design certification (DC) and combined license (COL) 
applications, (2) incorporation of guidance previously contained in ISG 
DC/COL-ISG-020 (ADAMS Accession No. ML100491233) concerning review of 
information from PRA-based seismic margin analyses submitted in support 
of DC and COL applications, (3) incorporation of guidance previously 
contained in ISG DI&C/COL-ISG-003 (ADAMS Accession No. ML080570048) 
concerning review of digital instrumentation and control system PRAs, 
including common cause failures in PRAs and uncertainty analysis 
associated with new reactor digital systems, and (4) incorporation of 
additional procedures for review of PRA information and severe accident 
assessments developed during NRC reviews of DC and COL applications 
completed after ISG DC/COL-ISG-003 was issued. A redline document 
comparing Revision 2 and the current proposed Revision 3 can be found 
under ADAMS Accession No. ML12153A008. The NRC staff issues Federal 
Register notices to facilitate timely implementation of the current 
staff guidance and to facilitate activities associated with the review 
of amendment applications. The NRC staff intends to incorporate the 
final approved guidance into the next revision of NUREG-0800, SRP 
Section 19.0 Revision 3. Therefore, the comment submittal period is 
extended from the original date of November 8, 2012 to December 8, 
2012.
