SUPPLEMENTARY INFORMATION: The purpose of the meetings is for panel review, discussion, evaluation, and recommendation on applications for Certificates of Indemnity submitted to the Federal Council on the Arts and the Humanities, for exhibitions beginning on or after July 1, 2015. The meeting held May 21, 2015, will discuss applications for Certificates for domestic exhibitions and the meeting held May 28, 2015, will discuss applications for Certificates for international exhibitions. Because the meeting will consider proprietary financial and commercial data provided in confidence by indemnity applicants, and material that is likely to disclose trade secrets or other privileged or confidential information, and because it is important to keep the values of objects to be indemnified, and the methods of transportation and security measures confidential, I have determined that that the meeting will be closed to the public pursuant to subsection (c)(4) of section 552b of Title 5, United States Code. I have made this determination under the authority granted me by the Chairman’s Delegation of Authority to Close Advisory Committee Meetings, dated July 19, 1993. Dated: April 27, 2015.

II. Discussion Electrical enclosures are a potential source of fire in nuclear power plants because they contain both combustible materials and live electrical circuits. These fires have the potential to disrupt power, instrumentation, and control in the plant. Key parameters affecting fire in an electrical enclosure include its size, openings, electrical voltage, and combustible load. This report documents the results from 112 fullscale experiments conducted by the National Institute of Standards and Technology at the Chesapeake Bay Detachment of the Naval Research Laboratory to better quantify the heat release rate (HRR) and burning behavior of electrical enclosures. Eight electrical enclosures were acquired from Bellefonte Nuclear Generating Station, a plant owned by the Tennessee Valley Authority located in Hollywood, Alabama. The enclosures were originally low voltage control cabinets, but in the experiments they were reconfigured with various amounts and types of electrical cable to represent other kinds of enclosures that would be found in a typical plant. An oxygen consumption calorimeter was built on site to measure the HRR of the fire as a function of time. The peak HRR varied from 0.3 kW to 576 kW.

ACTION: Exemption; issuance. AGENCY: VerDate Sep<11>2014 18:14 Apr 30, 2015 Jkt 235001 The U.S. Nuclear Regulatory Commission (NRC) is issuing an exemption in response to a May 16, 2013, request from Northern States Power Company (NSPM or the licensee), a Minnesota corporation doing business as Xcel Energy, for its specific license to operate an independent spent fuel storage installation (ISFSI) at the Prairie Island (PI) Nuclear Generating Plant. The licensee seeks relief from a regulatory provision with regard to the location of the primary alarm station. DATES: Notice of issuance of exemption is given on May 1, 2015.

SUPPLEMENTARY INFORMATION: SUMMARY: I. Background The licensee possesses a specific license under part 72 of Title 10 of the Code of Federal Regulations (10 CFR) for the storage of spent fuel in an ISFSI at the PI Nuclear Generating Plant. Section 72.180, ‘‘Physical protection plan,’’ requires the licensee to comply with the physical protection requirements in 10 CFR 73.51, ‘‘Requirements for the physical protection of stored spent nuclear fuel and high-level radioactive waste.’’ The licensee is subject to the requirements of 10 CFR 73.51(d)(3), which specifies the location, components, and requirements for the primary alarm station for the ISFSI. II. Request/Action By letter dated May 16, 2013, NSPM submitted a request for an exemption PO 00000 Frm 00091 Fmt 4703 Sfmt 4703 from a specific portion of the requirements of 10 CFR 73.51(d), ‘‘Physical protection systems, components, and procedures.’’ Specifically, the licensee seeks relief from a regulatory provision of 10 CFR 73.51(d)(3) with regard to the location of the primary alarm station. The NRC has the authority under 10 CFR 73.5 to grant a specific exemption from these requirements if the exemption is authorized by law and will not endanger life or property or the common defense and security, and the exemption is otherwise in the public interest. III. Discussion In accordance with the provisions of 10 CFR 73.21, physical protection plans for the storage of spent fuel and highlevel radioactive waste are protected as Safeguards Information. This exemption request pertains to the location of the primary alarm station. The NRC evaluated the exemption request in greater detail in the safety evaluation report (SER). The SER is withheld from public disclosure in accordance with 10 CFR 2.390 because it contains security information. A. Regulatory Evaluation In the final rule, ‘‘Physical Protection for Spent Nuclear Fuel and High-Level Radioactive Waste’’ (63 FR 26955; May 15, 1998), the introductory text of 10 CFR 73.51(d) was revised to more clearly indicate the Commission’s intent that alternative measures may also be acceptable for meeting the performance objectives of 10 CFR 73.51(d). B. Technical Evaluation Pursuant to 10 CFR 73.5, the Commission may, upon application by any interested person or upon its own initiative, grant such exemptions from the requirements of the regulations in 10 CFR part 73 as it determines are authorized by law, will not endanger life or property or the common defense and security, and are otherwise in the public interest. The NRC reviewed this request to determine whether the exemption should be granted. The NRC’s evaluation of this exemption request is set forth in the SER. The NRC has found that the NSPM meets the criteria for an exemption in 10 CFR 73.5. The NRC has determined that granting the exemption will not result in a violation of the Atomic Energy Act of 1954, as amended, or otherwise violate the Commission’s regulations. Therefore, the exemption is authorized by law. This exemption would not reduce the safeguards effectiveness of the physical security plan, and would E:\FR\FM\01MYN1.SGM 01MYN1
