1.0 INTRODUCTION

By application dated June 9, 2017, as supplemented by letter dated September 21, 2017 (Agencywide Documents Access and Management System Accession Nos. ML 17160A405 and ML 17264A750, respectively), Omaha Public Power District (OPPD, the licensee) requested changes to the Technical Specifications (TSs; Appendix A to Renewed Facility Operating License No. DPR-40) for the Fort Calhoun Station, Unit 1 (FCS). The proposed amendment would delete TS 2.8.3(6), "Spent Fuel Cask Loading," and associated Figure 2-11, "Limiting Burnup Criteria for Acceptable Storage in Spent Fuel Cask"; TS 3.2, Table 3-5, item 24, "Spent Fuel Cask Loading";

TS 4.3.1.3, Design Features associated with spent fuel casks; and portions of TS 3.2, Table 3-4, item 5, footnote (4) on boron concentration associated with cask loading. The supplemental letter dated September 21, 2017, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the U.S. Nuclear Regulatory Commission (NRC) staff's original proposed no significant hazards consideration determination as published in the Federal Register on August 15, 2017 (82 FR 38718).

2.0 REGULATORY EVALUATION

The requested amendment concerns criticality controls and loading of spent fuel casks. Currently, criticality requirements concerning spent fuel casks are in TS 2.8.3(6), "Spent Fuel Cask Loading," and associated Figure 2-11, "Limiting Burnup Criteria for Acceptable Storage in Spent Fuel Cask"; TS 3.2, Table 3-5, item 24, "Spent Fuel Cask Loading";

TS 4.3.1.3, Design Features associated with spent fuel casks; and portions of TS 3.2, Table 3-4, item 5, footnote (4) on boron concentration associated with cask loading. These requirements were placed into the TS by Amendment No. 239 dated April 10, 2006 (ADAMS Accession No. ML061000597).

The April 10, 2006, license amendment was prompted by Regulatory Issue Summary (RIS} 2005-05, "Regulatory Issues Regarding Criticality Analyses for Spent Fuel Pools and Independent Spent Fuel Storage Installations," dated March 23, 2005 (ADAMS Enclosure 2 Accession No. ML043500532), which had advised reactor licensees that they must meet both the requirements of Section 50.68 of Title 1 O of the Code of Federal Regulations (1 O CFR) and 10 CFR Part 72 with respect to subcriticality during storage cask loading in spent fuel pools. Section 50.68 describes the requirements for maintaining subcriticality of fuel assemblies in the spent fuel pool. However, the Commission later amended 10 CFR 50.68 to state that the criticality accident requirements of 10 CFR 50.68(b) do not apply to fuel within a package or cask in a spent fuel pool. As the Commission explained when amending the rules (71 FR 66648; November 16, 2006, as confirmed by 72 FR 3705; January 26, 2007) (confirming effective date of new rule), the criticality accident requirements of 10 CFR Parts 71 or 72, as applicable, apply to fuel within a package or cask in a spent fuel pool. As a result of the rulemaking, a licensee moving fuel between the spent fuel pool and a package or cask need only analyze fuel within the package or cask according to 10 CFR Parts 71 or 72, as applicable, and is not required to analyze fuel within the package or cask using 10 CFR 50.68(b) requirements.

Section 50.68(c) of 10 CFR eliminated an unnecessary burden of addressing spent fuel criticality analyses for spent fuel pools under 10 CFR 50.68 and Independent Spent Fuel Storage Installations (ISFSI) under 10 CFR Part 72. In light of 50.68(c), there is no need for additional redundant criticality controls in the TS. Through operation of 10 CFR 72.210, a general license is issued for the storage of spent fuel in an ISFSI at power reactor sites to persons authorized to possess or operate nuclear power reactors under 10 CFR Part 50. Through operation of 10 CFR 71.71(a), a general license is issued to any licensee of the Commission to transport, or to deliver to a carrier for transport, licensed material in a package for which a license, certificate of compliance, or other approval has been issued by the NRC. 3.0 TECHNICAL EVALUATION In reviewing this amendment request, the acceptance criterion used by the NRC staff was that the criticality controls to be eliminated from the TS were, in fact, those controls addressed by 10 CFR 50.68(c).

The NRC staff also considered whether any other licenses would be impacted by determining whether other licenses directly or indirectly takes credit for, or assumed the presence of, some aspect of the 10 CFR Part 50 license. Revising portions of TS 3,2, Table 3-4, item 5, footnote (4) to remove a reference to a normal operations sampling tests of spent fuel casks in the spent fuel pool is acceptable because OPPD is prohibited from operating the reactor or placing fuel in the reactor vessel at FCS pursuant to 10 CFR 50.829a)(2), and is no longer in a configuration or a condition under which the TS apply. On September 21, 2017, the licensee explained that although some station 1 O CFR Part 50 programs (i.e., Radiation Protection, Chemistry, Training, etc.) are credited in the 10 CFR Part 72 general license, there is no overlap between the programs and the requested license amendment.

In addition, the licensee affirmed that deleting these TS sections will not have any adverse impact on its cask loading requirements.

The NRC staff confirmed that the TS sections to be removed address criticality analyses for the casks, and that these analyses are no longer required due to 1 O CFR 50.68(c).

Therefore, the licensee's requested changes to delete TS 2.8.3(6), TS 3.2, Table 3-5, item 24, and Design Feature TS 4.3.1.3 are acceptable.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Nebraska State official was notified of the proposed issuance of the amendment on January 3, 2018. The State official had no comments.

5.0 ENVIRONMENTAL

CONSIDERATION The amendment changes a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure.

The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration and there has been no public comment on such finding published in the Federal Register on August 15, 2017 (82 FR 38718). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 1 O CFR 51.22(c)(9).

Pursua.nt to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
