Impact Dynamics
Following the events of September 11, 2001, ANATECH has been active in advancing methodologies for assessing structural damage due to extreme impact loading. Under contracts with Electric Power Research Institute, ANATECH conducted research in the analytical methods for assessing structural response under aircraft impact and provided analyses and engineering evaluations for the vulnerability of structures at operating U.S. nuclear power plants.
These structures included reinforced and prestressed concrete containments, steel containments with shield buildings, spent fuel pools, reactor buildings, auxiliary buildings, spent fuel storage casks and vaults, and spent fuel transportation casks. This research provided the basis for the development of the industry guidance for evaluating aircraft impact, NEI 07-13 Methodology for Performing Aircraft Impact Assessments for New Plant Designs, Section 2. This methodology and guidance has been accepted by the U. S. Nuclear Regulatory Commission in Regulatory Guide 1.217, Guidance for the Assessment of Beyond-Design-Basis Aircraft Impacts. ANATECH has applied this methodology to provide aircraft impact assessments (AIA) for meeting regulatory requirements for aircraft impact in 10 CFR 50.150 to many new plant designs both in the U.S. and abroad.
