Mr. Ladd has over twenty five years of experience in fire protection engineering and has had major responsibilities in both commercial nuclear and federal governmental projects including all aspects of fire protection program development and implementation. Mr. Ladd's experience includes fire modeling, fire risk quantification, fire PRA peer review, penetration seal evaluation and databases, preparation of engineering evaluations and calculations, Fire Hazards Analyses, and NFPA code conformance evaluations and deviations.

 

Tonya Enos-Sylla
Ms. Enos-Sylla has experience performing tasks related to Probabilistic Risk Assessment (PRA): Thermal-hydraulic Analysis, Human Reliability Analysis (HRA), developing, updating, converting and testing Configuration Risk Management (CRM) models, updating and evaluating PRA models. She also has experience with Fire PRA and Flooding Analysis. Ms. Enos-Sylla is familiar with a variety of computer software associated with PRA and FPRA including CAFTA, FTRex, HRA Calculator, MAAP, EOOS, ORAM-Sentinel, PARAGON, FRANC and FRANX.

 

Randy Best
Mr. Best has more than 25 years of experience in nuclear power plant operations and support, including over 21 years of Probabilistic Risk Assessment experience. He has had major responsibilities at both the site and corporate level for nuclear PRA projects and in all aspects of PRA development and implementation. Mr. Best’s experience includes development of PRA models for internal events (Level 1 and Level 2), internal fires and internal flooding for both commercial and DOE facilities. Additional work includes PRA input to licensing activities, configuration risk management and Maintenance Rule program coordination, and energy risk management fields.

Nuclear Safety Associates Instructors

Sam Swan

Mr. Swan has over 35 years of experience in the risk assessment of critical systems serving commercial, industrial and electric utility operations. His expertise includes the reliability of critical systems in disaster events, such as earthquakes, hurricanes, tornados, floods, fires and prolonged power outages. He was the primary investigator for a program sponsored by the Electric Power Research Institute (EPRI), in conjunction with the U.S. Nuclear Regulatory Commission (NRC), to quantify the earthquake vulnerability (seismic fragility) of equipment critical for nuclear power plant safety. Mr. Swan has performed numerous other studies estimating the seismic failure probability of critical components of nuclear utility systems and industrial operations. He has developed seismic risk assessments using equipment seismic fragilities, earthquake intensity and frequency data, seismic qualification information for equipment and interconnections, stress computations, compilations of shake table data, and the application of engineering judgment based on experience from past earthquakes. He obtained a B.S. degree in Mechanical Engineering from the University of Arizona, and both the M.S. and Professional Engineer degrees in Mechanical Engineering from Stanford University.

 

Tony Chung
Mr. Chung has over 30 years of experience in design engineering, including seismic, structural and dynamic impact analyses. He has served as the principal engineer at SAIC for a natural phenomena hazard analysis (seismic, wind, flood), and performed many structural and stress analyses of buildings and systems, including nuclear power and weapons facilities, for the U.S. NRC and U.S. Department of Energy (DOE). He has also developed seismic capacity margins for non-reactor buildings, and performed structural walk-downs, reviews of seismic, tornado, and aircraft crash accident analyses, and provided predictions of the structural integrity for various DOE high-hazard facilities. He has developed nonlinear dynamic capacity-spectrum to find the ultimate structural collapse threshold capacity for buildings, including missile impacts on walls, planks, cages, and specific facility equipment. He has prepared equipment and structural qualification documentation for nuclear facility FSARs. He obtained a B.S. degree in Mechanical Engineering from Chung-Hsing University in Taiwan, and the M.S. degree in Mechanical Engineering from Washington State University. He is a registered PE in Structural Engineering at the State of Idaho.
