Installation

AGENCY: Nuclear Regulatory Commission.

[[Page 42744]]


ACTION: Environmental assessment and finding of no significant impact; 
issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is considering a 
license amendment request for the Virginia Electric and Power Company's

operation of North Anna Power Station's (NAPS) independent spent fuel 
storage installation (ISFSI). The proposed amendment would revise the 
technical specifications (TSs) to allow the loading and storing of high 
burnup spent nuclear fuel from NAPS, Units 1 and 2, in a single, 
modified (and instrumented) TN-32B HBU cask.

SUPPLEMENTARY INFORMATION: 

I. Introduction

    The NRC is considering issuance of a license amendment for 
Dominion's SNM License SNM-2507 for the NAPS ISFSI located in Louisa 
County, Virginia (ADAMS Accession No. ML15239B251 and ML15289A189). 
Dominion is proposing to revise the TSs to allow the loading and 
storing of high burnup spent nuclear fuel (i.e., spent fuel with burnup 
greater than 45,000 megawatt days per metric ton of uranium (MWD/MTU)) 
from NAPS, Units 1 and 2, in a single, modified (and instrumented) TN-
32B HBU cask.
    The NRC staff has prepared a final environmental assessment (EA) as 
part of its review of this proposed license amendment in accordance 
with the requirements in part 51 of title 10 of the Code of Federal 
Regulations (10 CFR) ``Environmental Protection Regulations for 
Domestic Licensing and Related Regulatory Functions.'' Based on the 
final EA, the NRC has determined that an environmental impact statement 
is not required for this proposed action and a finding of no 
significant impact (FONSI) is appropriate. The NRC is also conducting a 
safety evaluation of the proposed license amendment pursuant to 10 CFR 
part 72, ``Licensing Requirements for the Independent Storage of Spent 
Nuclear Fuel, High Level Radioactive Waste, and Reactor-Related Greater 
than Class C Waste,'' and the results will be documented in a separate 
Safety Evaluation Report (SER). If Dominion's request is approved, the 
NRC will issue the license amendment following publication of this 
final EA and FONSI and the SER.

II. Final Environmental Assessment Summary

    Dominion is requesting to amend its specifically-licensed ISFSI to 
load and store high burnup spent nuclear fuel from NAPS, Units 1 and 2, 
in a single, modified (and instrumented) TN-32B HBU cask. Specifically, 
the TN-32B HBU cask will be modified to insert thermocouples through 
the cask lid and into the fuel assemblies to monitor fuel temperatures 
in the cask. The data gathered will support the U.S. Department of 
Energy and Electric Power Research Institute High Burnup Dry Storage 
Research Project. Dominion is proposing to revise the TSs that address 
the functional and operating limits, the limiting condition for 
operation, and the design features to reflect the use of the TN-32B HBU 
cask. As part of the High Burnup Dry Storage Research Project, Dominion 
will monitor the fuel temperature in this cask and collect data to 
support research on the long-term behavior of high burnup spent nuclear 
fuel. The information will be used to inform dry cask designs and 
future ISFSI licensing actions. If the proposed license amendment is 
approved, Dominion will load the TN-32B HBU cask with high burnup spent 
nuclear fuel and place it on the single vacant spot in the 
specifically-licensed ISFSI Pad 1.
    The NRC has assessed the potential environmental impacts of the 
proposed action, and alternatives to the proposed action including the 
use of the Transnuclear, Inc., Standardized NUHOMS[supreg] Cask System 
under the generally-licensed ISFSI and the no-action alternative. The 
results of the NRC's environmental review can be found in the final EA 
(ADAMS Accession No. ML16168A104). The NRC staff performed its 
environmental review in accordance with the requirements in 10 CFR part 
51. In conducting the environmental review, the NRC considered 
information in the license amendment application (ADAMS Accession No. 
ML15239B251); information in the responses to the NRC's requests for 
additional information (ADAMS Accession No. ML16097A213 and 
ML16097A219); communications and consultation with the Virginia State 
Historic Preservation Office, the U.S Fish and Wildlife Service (FWS), 
and the Virginia Department of Health.
    Approval of Dominion's proposed license amendment would allow the 
TN-32B HBU cask to be placed on the specifically-licensed ISFSI Pad 1. 
Changes to routine operations or maintenance of the NAPS specifically-
licensed ISFSI would consist of downloading the data from the data 
logger on a quarterly basis. Dominion calculated the total dose rate at 
the site boundary from the placement of this one TN-32B HBU cask and 
determined that the dose would be 0.937 mrem/year. Adding the total 
dose rate from the placement of the TN-32B HBU cask to the maximum 
combined radiation contribution to the nearest permanent resident from 
the operation of the ISFSI and the NAPS, Units 1 and 2 (5.10 mrem/
year), would result in a total combined dose rate of 6.037 mrem/year, 
which is below the 25 mrem/year regulatory limit in 10 CFR 72.104. In 
addition, the NRC reviews and oversees casks to ensure these are 
designed and maintained in accordance with the regulatory limits in 10 
CFR parts 20 and 72. Furthermore, Dominion maintains a radiation 
protection program for NAPS, Units 1 and 2, and the specifically-
licensed and generally-licensed ISFSIs

[[Page 42745]]

in accordance with 10 CFR part 20 to ensure that radiation doses are as 
low as is reasonably achievable. Accordingly, no significant 
radiological or non-radiological impacts are expected to result from 
approval of the license amendment request, and the proposed action 
would not significantly contribute to cumulative impacts at the NAPS 
site. Additionally, there would be no disproportionately high and 
adverse impacts on minority and low-income populations. Furthermore, 
the NRC staff determined that this license amendment request does not 
have the potential to cause effects on historic properties, assuming 
those were present; therefore, in accordance with 36 CFR 800.3(a)(1), 
no consultation is required under Section 106 of the National Historic 
Preservation Act. The NRC staff, however, reached out to and informed 
the Virginia State Historic Preservation Officer and the Pamunkey Tribe 
of Virginia of its determination via letters dated April 12, 2016, and 
January 21, 2016, respectively (ADAMS Accession No. ML16098A212 and 
ML16020A342, respectively). The NRC staff also consulted with the FWS 
in accordance with Section 7 of the Endangered Species Act. The NRC 
staff used FWS Virginia Field Office's Ecological Services online 
project review process. The self-certification letter dated April 8, 
2016 (ADAMS Accession No. ML16118A168), stated that ``additional 
coordination with this office is not needed.'' The NRC completed the 
certification process by submitting the online review package to the 
FWS Virginia Field Office via letter dated May 2, 2016 (ADAMS Accession 
No. ML16120A189). In conclusion, the NRC staff finds that the proposed 
action will not result in a significant effect on the quality of the 
human environment.

III. Finding of No Significant Impact

    Based on its review of the proposed action, in accordance with the 
requirements in 10 CFR part 51, the NRC has concluded that the license 
amendment request for the Dominion's SNM License Number SNM-2507 for 
the operation of NAPS' ISFSI located in Louisa County, Virginia, will 
not significantly affect the quality of the human environment. 
Therefore, the NRC has determined, pursuant to 10 CFR 51.31, that 
preparation of an environmental impact statement is not required for 
the proposed action and a finding of no significant impacts is 
appropriate.

    Dated at Rockville, Maryland, this 24th day of June, 2016.
