| Title | Relying on the Use of Friction as a Restraining Force when the HI-TRAC is Placed on top of the HI-STORM |
| Description | A violation of very low safety significance of 10 CFR 72.212 (b)(2)(i)(B), Conditions of a General License Issued under 72.210, was identified by the inspectors for the failure to perform adequate evaluations of the Independent Spent Fuel Storage Installation (ISFSI) pad. Specifically, the inspectors identified four examples where the licensee failed to design the ISFSI pad to adequately support the static and dynamic loads of the stored casks, considering potential amplification of earthquakes through soil-structure interaction (SSI). The licensee documented the conditions in IR 957945 and IR 1102835. As an interim corrective action, the licensee provided a technical paper providing justification for partial loading of the pad with 10 casks. Because this violation was related to an ISFSI license, it was dispositioned using the traditional enforcement process using Section 6.5.d.1 of the Enforcement Policy. The inspectors determined that the performance deficiency was more than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Dispositioning Screening, because if left uncorrected, a failure of the ISFSI pad could lead to a more significant safety concern. This violation is being treated as a NCV consistent with Section 2.3.2 of the NRC Enforcement Policy. The violation screened as having very low safety significance (Severity Level IV). |
