Request for Additional Information - Davis Besse Flooding Hazard Report (TAC No. MF3721)
Mr. Lashley, By letter dated March 11, 2014, (Agencywide Documents Access and Management System (ADAMS) at Accession No. ML14070A108) FirstEnergy provided a response to the 10 CFR 50.54(f) letters regarding the flooding aspects of recommendation 2.1 of the Near-Term Task Force Review of insights from the Fukushima Dai-ichi accident for the Davis-Besse Nuclear Power Station (DBNS).
Based on a review of the submittal, the NRC staff has determined that the following additional information (RAIs) are required in order to complete its review. The request for additional information was previously provided to you in draft form. It was agreed that a response to these RAIs would be provided by August 27, 2014. Should the NRC determine that these RAIs are no longer necessary prior to the scheduled date, the request will be withdrawn. If circumstances result in the need to revise the requested response date, please contact me at (301) 415-1132 or via e-mail at joseph.sebrosky@nrc.gov. The NRC staff has determined that no security-related or proprietary information is contained herein.
Sincerely, Joe Sebrosky Senior Project Manager Japan Lessons-Learned Division Office of Nuclear Reactor Regulation joseph.sebrosky@nrc.gov 301-415-1132 Request for Additional Information Associated with Review of March 11, 2014, submittal RAI #1: To support the NRCs review of the Recommendation 2.1 flood hazard reevaluation report, the licensee is requested to provide electronic versions of the following input and output files:
- Delft-3d model grid file and the model files that define grid properties (bottom friction, roughness, etc.)
at specific locations.
- Delft-3d model control files (file(s) that define model parameters such as time step, parameter settings, run properties, etc.)
- Delft-3d input files necessary to execute the model calibration and validation runs. Output files for calibration and validation runs to allow confirmation of water level and wave results.
- Digital Elevation Model (DEM) data
- Input and output files associated with the HEC-HMS and HEC-RAS river flooding analysis
- Input and output files associated with the HEC-RAS dam failure assessment
- Input and output files associated with the HEC-RAS ice-induced flooding assessment
- Input and output files associated with the FLO-2D assessment of local intense precipitation 1
