Download as PDF Federal Register / Vol. 70, No. 143 / Wednesday, July 27, 2005 / Notices License No. DPR–23 issued to the Carolina Power and Light Company (the licensee) for operation of the H.B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP2) located in Darlington County, South Carolina. The NRC is issuing this environmental assessment pursuant to 10 CFR 51.21 and is making a finding of no significant impact (FONSI). Environmental Assessment Identification of the Proposed Action The proposed action would exempt the licensee from the requirements of 10 CFR 50.68, ‘‘Criticality Accident Requirements,’’ subsection (b)(1) during the spent fuel pool activities related to the underwater handling, loading, and unloading of the dry shielded canister (DSC) NUHOMS -24PTH as described in proposed Amendment No. 8 to Certificate of Compliance No. 1004 listed in 10 CFR 72.214. The proposed action is in accordance with the licensee’s application dated February 22, 2005, as supplemented on May 10 and July 6, 2005. The Need for the Proposed Action In 10 CFR 50.68(b)(1), the Commission sets forth the following requirement that must be met in lieu of a monitoring system capable of detecting criticality events: Plant procedures shall prohibit the handling and storage at any one time of more fuel assemblies than have been determined to be safely subcritical under the most adverse moderation conditions feasible by unborated water. Section 50.12(a) of 10 CFR allows licensees to request an exemption from the requirements of 10 CFR Part 50 if the application of the regulation is not necessary to achieve the underlying purpose of the rule and special conditions are met. The licensee stated that compliance with 10 CFR 50.68(b)(1) is not necessary for underwater handling, loading, and unloading of the DSC NUHOMS–24PTH in the HBRSEP2 spent fuel pool to achieve the underlying purpose of the rule. The NRC has completed its safety evaluation of the proposed action and concludes that the underlying purpose of 10 CFR 50.68(b)(1) will still be satisfied if the exemption is granted. The details of the NRC 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. VerDate jul<14>2003 19:40 Jul 26, 2005 Jkt 205001 Environmental Impacts of the Proposed Action 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 significant increase in occupational or public radiation exposure. Therefore, there are no significant radiological impacts associated with the proposed action. With regard to potential nonradiological impacts, the proposed action does not have a potential to affect any historic sites. It does not affect nonradiological plant effluents and has no other environmental impact. Therefore, there are no significant non-radiological 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 HBRSEP2 dated April 1975, and the Final Supplemental Environmental Impact Statement (NUREG–1437 Supplement 13) dated December 2003. Agencies and Persons Consulted On July 11, 2005, the staff consulted with the South Carolina State official, Mr. Michael Gandy of the South Carolina Department of 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 set forth above, the NRC concludes that the proposed action will not have a significant effect on the quality of the human environment and is therefore issuing this FONSI. Accordingly, the NRC has determined not to prepare an environmental impact statement for the proposed action.

SUPPLEMENTARY INFORMATION: The U.S. Nuclear Regulatory Commission (NRC or Commission) is considering a request dated March 21, 2005, from Entergy Operations, Inc. (applicant or Entergy Operations) for exemption from the requirements of 10 CFR 72.212(a)(2) and 10 CFR 72.214 pursuant to 10 CFR 72.7, for the Arkansas Nuclear One (ANO), E:\FR\FM\27JYN1.SGM 27JYN1 43464 Federal Register / Vol. 70, No. 143 / Wednesday, July 27, 2005 / Notices Unit 1 and Unit 2 Independent Spent Fuel Storage Installation, located 6 miles west-northwest of Russellville, Arkansas. In consideration of the request, the NRC would also grant exemption from the requirements of 10 CFR 72.212(b)(2)(I) and 72.212(b)(7). The exemption would authorize the applicant to store damaged spent nuclear fuel (SNF) assemblies in a Holtec HI–STORM 100, Amendment 1 design, Multi-Purpose Canister (MPC) –32. Environmental Assessment (EA) I. Identification of Proposed Action By letter dated March 21, 2005, Entergy Operations requested an exemption from the requirements of 10 CFR 72.212(a)(2) and 10 CFR 72.214, specifically, exemption from complying with Appendix B, Section 2.1, of the HI–STORM 100 Cask System CoC (1014), Fuel Specifications and Loading Conditions. The NRC action would also include granting exemption from the requirements of 10 CFR 72.212(b)(2)(I) and 72.212(b)(7). Approval of the exemption request would allow storage of uncanned damaged SNF assemblies in a HI–STORM 100, Amendment 1 design, MPC–32. Damaged SNF assemblies may be stored in an HI– STORM 100, Amendment 2 design, MPC–32 when properly canned. Entergy Operations has identified five previously loaded intact fuel assemblies that have been reclassified as damaged SNF assemblies. A damaged SNF assembly is defined in the HI–STORM 100, Amendment 1 CoC in part as one with greater than pinhole leak or hairline cracks. Each of the five SNF assemblies classified as damaged contain one interior rod characterized as defective. In accordance with Amendment 1 to CoC 1014 granted to Holtec for the HI–STORM 100 cask system, and as codified in 10 CFR 72.214, the MPC–32 is not permitted to store damaged fuel assemblies. ANO as a general licensee, is authorized by the NRC to use spent fuel storage casks approved under 10 CFR Part 72, Subpart K. For the NRC to permit Entergy Operations to continue to store the five uncanned damaged SNF assemblies in four HI–STORM 100, Amendment 1 design, MPC–32’s, the NRC, must grant Entergy Operations an exemption from the general license conditions defined in 10 CFR 72.212. The regulations in 10 CFR 72.212 state that the general license for storage of SNF at power reactor sites is limited to storage of SNF in casks approved under the provisions in 10 CFR Part 72. By exempting Entergy VerDate jul<14>2003 19:40 Jul 26, 2005 Jkt 205001 Operations from 10 CFR 72.214 and 72.212(a)(2), 72.212(b)(2)(I), and 72.212(b)(7), Entergy Operations will be authorized to use its general license to store uncanned damaged SNF assemblies in the HI–STORM 100, Amendment 1 design, MPC–32. The proposed action before the Commission is whether to grant the exemption under 10 CFR 72.7. The ISFSI is located 6 miles westnorthwest of Russellville, Arkansas, on the ANO Power Plant site. The ANO ISFSI is an existing facility constructed for interim dry storage of spent ANO nuclear fuel. II. Need for the Proposed Action Five uncanned damaged SNF assemblies are currently loaded into four HI–STORM 100, Amendment 1 design, MPC–32’s stored at the ANO ISFSI. Unloading of the damaged SNF assemblies would subject personnel to a significant unnecessary dose, generate additional contaminated waste, increase the risk of a possible fuel handling accident, and increase the risk of a heavy load handling accident. Discharge of the damaged SNF assemblies from storage in the MPCs would result in inadequate storage capacity in the ANO Unit 2 Spent Fuel Pool. If the damaged SNF assemblies are discharged into the spent fuel pool, storage of new fuel and the restoration of normal full core offload capability prior to and after the next refueling outage would be challenged. Recovery of spent fuel pool space could be significantly hindered due to double handling of ANO Unit 2 fuel in addition to material and scheduling conflicts with ANO Unit 1 activities to the extent that ANO Unit 2 core offloads could be jeopardized. III. Environmental Impacts of the Proposed Action The potential environmental impact of using the HI–STORM 100 system was initially presented in the Environmental Assessment for the final rule to add the HI–STORM 100 system to the list of approved spent fuel storage casks in 10 CFR 72.214 (65 FR 25241; May 1, 2000). Furthermore, each general licensee must assess the environmental impacts of the specific ISFSI in accordance with the requirements of 10 CFR 72.212(b)(2)(iii). This section requires the general licensee to perform written evaluations to demonstrate compliance with the environmental requirements of 10 CFR 72.104, ‘‘Criteria for radioactive materials in effluents and direct radiation from an ISFSI or MRS [Monitored Retrievable Storage Installation].’’ PO 00000 Frm 00075 Fmt 4703 Sfmt 4703 The HI–STORM 100 system is designed to mitigate the effects of design basis accidents that could occur during storage. Design basis accidents account for human-induced events and the most severe natural phenomena reported for the site and surrounding area. Postulated accidents analyzed for an ISFSI include tornado winds and tornado generated missiles, design basis earthquake, design basis flood, accidental cask drop, lightning effects, fire, explosions, and other incidents. Considering the specific design requirements for each accident condition, the design of the HI–STORM 100, Amendment 1, cask system using an MPC–32 basket design, would prevent loss of containment, shielding, and criticality control. The loading of damaged SNF has no impact on the structural aspects of the containment boundary. The HI–STORM 100, Amendment 1 design permits storage of damaged SNF assemblies in the MPC– 24 and MPC 68 which utilize the same outer containment boundary as the MPC–32. Dose surveys performed prior to placing each cask in service, including those MPC–32s containing the damaged SNF assemblies, demonstrated that each cask satisfied the dose requirements defined in the HI–STORM 100 Amendment 1 CoC. Any relocation of the damaged fuel rods, in the fuel assembly, within the MPC has a negligible effect on the keff (criticality control) of the system predominantly due to the fact that there are no more than two individual damaged fuel rods per MPC. Without the loss of either containment, shielding, or criticality control, the risk to public health and safety from the continued storage of five damaged SNF assemblies in four HI– STORM 100, Amendment 1 design, MPC–32s, is not compromised. By permitting the continued storage of five uncanned damaged SNF assemblies using HI–STORM 100 system, Amendment 1 design, MPC–32s, there will be no additional occupational exposure due to unloading activities, and offsite dose rates will remain well within the 10 CFR Part 20 limits. Therefore, the NRC staff has determined that an acceptable safety margin is maintained and that there are no significant environmental impacts as a result of continuing to store five damaged SNF assemblies in four HI– STORM 100, Amendment 1, MPC–32s at the ANO ISFSI. IV. Alternatives to the Proposed Action The staff evaluated the alternative to the proposed action to deny approval of the exemption. Denial of the exemption request would result in unloading of the E:\FR\FM\27JYN1.SGM 27JYN1 Federal Register / Vol. 70, No. 143 / Wednesday, July 27, 2005 / Notices damaged SNF assemblies subjecting personnel to unnecessary dose, the generation of additional contaminated waste, an increase in the risk of a possible fuel handling accident, an increase in the risk of a heavy load handling accident, and result in inadequate storage capacity in the ANO Unit 2 Spent Fuel Pool jeopardizing the ability to fully offload the ANO Unit 2 core.

or Commission) is considering a request dated March 21, 2005, from
Entergy Operations, Inc. (applicant or Entergy Operations) for
72.214 pursuant to 10 CFR 72.7, for the Arkansas Nuclear One (ANO),
Unit 1 and Unit 2 Independent Spent Fuel Storage Installation, located
6 miles west-northwest of Russellville, Arkansas. In consideration of
the request, the NRC would also grant exemption from the requirements
of 10 CFR 72.212(b)(2)(I) and 72.212(b)(7). The exemption would
authorize the applicant to store damaged spent nuclear fuel (SNF)
assemblies in a Holtec HI-STORM 100, Amendment 1 design, Multi-Purpose

By letter dated March 21, 2005, Entergy Operations requested an
72.214, specifically, exemption from complying with Appendix B, Section
2.1, of the HI-STORM 100 Cask System CoC (1014), Fuel Specifications

exemption from the requirements of 10 CFR 72.212(b)(2)(I) and
72.212(b)(7). Approval of the exemption request would allow storage of
uncanned damaged SNF assemblies in a HI-STORM 100, Amendment 1 design,

each general licensee must assess the environmental impacts of the
specific ISFSI in accordance with the requirements of 10 CFR
