PLANT AND ISFSI STATUS

Arkansas Nuclear Ones (ANO) Independent Spent Fuel Storage Installation (ISFSI) stored twenty four Energy Solutions Ventilated Storage Cask (VSC) VSC-24 casks that had been loaded from 1996 to 2003. On the north side of the VSC-24 pad, ANO had loaded and stored thirty-seven Holtec casks with room on the pad to store eleven more. For the Holtec casks, two canister designs were used at ANO. The Multi-Purpose Canister (MPC) MPC-24 canister stored a maximum of twenty-four assemblies. The MPC-32 canister stored a maximum of thirty-two assemblies. All Unit 1 spent fuel was stored in the MPC-24 canister. Unit-2 spent fuel was stored in both the MPC-24 and MPC-32 canisters. The licensee used two versions of the Holtec HI-STORM concrete storage cask overpack designs at the ISFSI. The first twelve Holtec casks placed on the ISFSI pad were HI-STORM 100S overpacks (with nine MPC-24 canisters and three MPC-32 canisters). Since then, the HI-STORM 100S Version C overpacks have been used (containing eleven MPC-24 canisters and fourteen MPC-32 canisters).

(60855.1)

a. Inspection Scope

(1) Cask Transfer Facility Overview

There had been no loading operations performed since the last ISFSI inspection performed in December 2012. ANO had halted loading activities to construct a Cask Transfer Facility (CTF) outside the refueling building. This action was necessitated from an ANO internal review which identified errors in their trainbay floor loading calculations during a seismic event. This issue was previously reviewed by the NRC inspectors and was documented in the last ISFSI inspection report (ML13057A986).

ANO had performed a number of construction activities and purchased a variety of new equipment, since the last NRC ISFSI inspection, to support continued dry cask loading operations utilizing a Cask Transfer Facility. The CTF was classified as a Part 72 Important to Safety (ITS) structure. The CTF will support the stack-up configuration of a fully-loaded HI-TRAC, Mating Device, HI-STORM, and the Vertical Cask Transporter (VCT) during MPC transfer operations from the HI-TRAC into the HI-STORM. The ANO CTF is a passive reinforced concrete structure. The structure is composed of a base slab, four walls, and a top slab. The CTF features a 12-8 x 12-8 by approximately 14 feet deep cavity in the ground for placement of the empty HI-STORM prior to the MPC transfer. Inside of the cavity, four removable Upper Lateral Restraints and four removable Lower Lateral Restraints would be installed in the cavity to horizontally restrain the HI-STORM and assist in energy absorption and transferring loads to the surrounding soil during a seismic event.

The CTF was designed to accommodate both the HI-STORM 100S, Version C, and HI-STORM 100S, which are currently in use at ANO. The CTF was designed to support the combined loads of a fully-loaded HI-STORM 100S, Version C with high density concrete shielding during both placement and retrieval. In addition, the CTF is designed to physically accommodate the potential future use of HI-STORM 100S, Version B and HI-STORM Forced Wind (FW), both using high density concrete shielding.

To support transportation from the refueling building to the CTF, ANO had constructed two passive reinforced concrete turning pads with an embedded rail spur and a new rail heavy haul path that extended from the currently loaded ISFSI pads to the north-end of the ANO site to where the new CTF was located. The new CTF facility with haul path and turning pads will facilitate:

(1) unloading of the fully-loaded HI-TRAC/MPC from the Holtec Railcar;
(2) transfer of the fully-loaded HI-TRAC/MPC to the CTF for placement of the MPC within the HI-STORM; and
(3) transfer of the fully-loaded HI-STORM from the CTF to the ISFSI pad. At the time of the inspection the CTF was outside the existing site Protected Area (PA).

Eventually the PA fence will be extended around the new CTF facility. In the future, ANO plans to build four reinforced concrete storage pads which will provide for 94 storage casks with four temporary storage locations for placement of casks after the current ISFSI pads are filled.

The new equipment that ANO purchased included a new VCT, a low profile transporter, new MPC downloading slings, new HI-STORM slings, and new VCT special lifting device brackets to carry the HI-STORMs.

(2) Design and Evaluations of the Cask Transfer Facility

The ANO CTF was a reinforced concrete structure with designed minimum concrete compression strength of 4,500 psi at 28 days. All compressive strength test results that were reviewed demonstrated that the concrete compression strength exceeded the design requirement and were found to be greater than 5,000 psi. The CTF Environmental and Design Conditions were contained in the Holtec FSAR Section 2.3.3.1 B. The Design Basis Earthquake (DBE) event applicable to the CTF is in Holtec FSAR Section 2.3.3.1 B.vii and stated that the DBE should be specified as a set of response spectra or acceleration time-histories for use in the CTF structural and impact consequence analyses. Engineering Calculation (CALC)-13-D-2001-14, ANO CTF Seismic/Structural Report, provided a summary of the seismic-structural analyses, which were performed for the stack-up configuration of a fully-loaded HI-TRAC, Mating Device, and HI-STORM during MPC transfer operations from the HI-TRAC to the HI-STORM.

Other analyses were preformed that demonstrated continued compliance to the Holtec FSAR for environmental hazards which included flooding, lightning strike, explosions, fires, tornado winds, and tornado missiles. These analyses were documented in CALC-ANO-CS-13-00004, ANO CTF Hazards Technical Summary Report.

Inspectors reviewed the design of the heavy haul path from the existing ISFSI docking station to the ANO CTF. Engineering Change Report 45253 provided the design of the haul path based on the weight of a fully loaded HI-STORM and the weight of the VCT. Calculation-13-D-2001-12 Structural Evaluation of Haul Path at ANO evaluated the maximum bearing pressure under the concrete tracks, stability of the haul path, including sliding and overturning, and the reinforcement for the concrete tracks. The calculation determined that the maximum calculated bearing pressure of 3,245 psf was less than the allowable designed bearing pressure of 3,500 psf, the calculated factors of safety for sliding was 2.77 and the overturning was 4.91 which exceeded the minimum required factor of safety of 1.5 from NUREG-0800, Section 3.8.5. Also the steel reinforcement sizes, configurations, and lap splices lengths demonstrated compliance with the American Concrete Institute (ACI)-318 and ACI-349 requirements. All concrete compressive strength test results that were reviewed exceed their design requirements.

(3) Design and Evaluations of the Vertical Cask Transport

Inspectors reviewed documentation that demonstrated that the VCT had been load tested to 125 percent of its rated load. The VCT is rated to lift a maximum of 415,000 lbs. The 125 percent load test lifted slightly more than 518,750 lbs, meeting the requirement. A loaded HI-STORM 100S with high density concrete was documented as weighing 389,025 lbs. The loaded HI-STORM 100S weighs more than the loaded HI-STORM Version C with high density concrete (382,470 lbs).

The reason for the higher load rating was to accommodate the future use of the HI-STORM FW which contains more fuel assemblies than the HI-STORM 100S or HI-STORM Version C.

ANO had performed analyses to demonstrate the structural integrity and kinematic stability of the VCT under dead and seismic loads. These analyses were documented in CALC-ANO-CS-13-00009 Generic VCT Seismic Technical Summary Report and CALC-ANO-CS-13-00007 VCT Technical Summary Report.

The VCT that was purchased by ANO was found to be qualified to perform all operations associated with the loading activities at ANO.

(4) Special Lifting Devices and Slings

Documentation associated with the newly purchased special lifting devices for the HI-TRAC and HI-STORM were documented in Purchase Specification (PS)-2301-02 Purchase Specification for ANO HI-STORM/HI-TRAC Integrated Lifting Brackets.

The special lifting devices were documented as meeting American National Standard Institute (ANSI) N14.6 requirements as specified by the Holtec FSAR.

Additionally, all special lifting devices were load tested to 300% of the rated load as required by ANSI N14.6. These lift tests were documented in Documentation Package (DP) 13158-001 Lift Brackets for ANO.

The MPC downloader slings and HI-STORM slings that were purchased by ANO were proof load tested to 200 percent of their rated load. These proof load tests were documented in Certificate of Conformance (CoC) 13158-002 Lift Bracket Slings for ANO and CoC 13268-001 MPC Downloader Slings for ANO. The tests were performed in accordance with American Society of Mechanical Engineers (ASME) B.30.9 requirements.

(5) Corrective Action Program

A list of condition reports issued since the last NRC inspection in December of 2012, was provided by the licensee for ISFSI activities. Of the list of condition reports provided relating to the ISFSI and new CTF construction activities, four condition reports were selected by the NRC inspector for further review. The condition reports reviewed were well documented and properly categorized based on the significance of the issue. The corrective actions taken were appropriate for the situations. No NRC concerns were identified related to the condition reports reviewed.

(6) Observed Activities and Loading Procedures

During the week of the NRC inspection, ANO was in the process of performing the site acceptance testing of their new VCT. The inspector observed the raising and lowering of a weighted dummy MPC with the sites new downloading slings and the VCT. The VCT raised and lowered the weighted dummy MPC with no issues. ANO had prepared a new loading procedure to address the use of the CTF and VCT.

The NRC inspector reviewed Procedure 3406.005 HI-STORM and HI-Track Transport Operations Using LPT, VCT, and Holtec Rail Car for the use of the new equipment.
