Chief Technical Officer
Martin G. Plys, Sc.D., is a Vice President of Waste Technology & Post-Fukushima Services at Fauske & Associates, LLC (FAI), an affiliate of the Westinghouse Electric Company. After receiving Sc.D. from MIT in 1984, he began his career at FAI developing severe reactor accident models for the MAAP computer code. In 1988, he became Manager of Methods Development responsible for MAAP stewardship. In 1992, he was promoted to Vice President and moved to Brussels to assist Westinghouse with development of MAAP models for Russian reactor designs. In 1993, with MAAP/VVER completed, he moved back to the U.S. and began to focus on process safety and safety of wastes stored at the U.S. DOE Hanford site. Most recently, he has been a primary contributor to the technical bases for safe processing and storage of Hanford spent nuclear fuel (SNF) and sludge, explosive hazards analysis of the waste treatment plant (WTP) vitrification facility, and disposition of cesium and strontium waste capsules.
Dr. Plys has led development of FAI's general nuclear and chemical facility analysis program which is routinely used for a variety of Hanford projects including WTP, SNF, tank farms, and waste capsules. Model applications include in-facility combustion, fission product release, deposition, and transport, and fire hazards; in-vessel reactive waste transients; and evaluation of reactive metallic fuel and sludge processing, transport and storage. For the WTP, Dr. Plys has authored hydrogen design technical guidance, participated in management transition and due diligence, and was technical lead for the original explosive hazards analysis. His contributions to the Hanford SNF project included technical bases for pyrophoric behavior of SNF, process design and modeling, and post-process water content, radiolysis, chemical reactions, and long-term behavior. He is author of the advisory panel summary report for disposition of Cs and Sr waste capsules. Dr. Plys has also worked on litigation support defending Hanford contractors for Plutonium Finishing Plant operations. Dr. Plys' modeling contributions in severe reactor accident analyses include general flammability and combustion of gases, reactor material behavior during core melt, fission product release, aerosol transport and deposition, and general chemical equilibrium model development. In 2015 he was named a Fellow of the American Nuclear Society and also was named Consulting Engineer, Engineering Center of Excellence for FAI’s parent company, Westinghouse Electric Company, LLC.

Emeritus President and Regent Advisor
Dr. Hans K. Fauske (1935-2021)
It was with great sadness that we saw the passing of our company founder and namesake Dr. Hans K. Fauske, DSc. Hans touched the lives of countless people around the world through his illustrious career of technical leadership in nuclear and chemical process safety. Beyond his many scientific publications and awards he was an inspiring leader, patient mentor, tireless competitor, and devoted family man. We remember his intelligent companionship and are proud to continue the tremendous legacy he leaves in the process safety community.
Since leaving Argonne National Laboratory in 1980 to found Fauske & Associates, Inc., Hans was involved in many innovative projects covering a wide range of safety issues in the nuclear power and chemical process industries. He served as Senior Consultant to the Industry Degraded Core Rulemaking program (IDCOR) which resulted in the MAAP computer models for analyzing severe accidents in commercial nuclear power plants worldwide. He also provided overall technical direction for the AIChE Design Institute for Emergency Relief Systems (DIERS) which led to state-of-the-art methodology and laboratory tools for characterizing chemical systems and designing relief systems for storage and process equipment worldwide.
Dr. Fauske’s detailed obituary can be found here.
Emeritus Senior Vice President and Regent Consultant
Dr. Robert E. Henry is Emeritus Senior Vice President, Regent Consultant and co-founder of FAI which was founded in 1980. In this position, he has been responsible for developing the understanding of pressurized and boiling light water reactors during severe accident conditions. This knowledge base has been integrated into a large system code called MAAP (Modular Accident Analysis Program). MAAP has gained widespread acceptance in the domestic and foreign nuclear industry. This computer code models such phenomena as when core damage would (and would not) occur, core overheating, hydrogen formation, distribution, and combustion within the containment, debris distribution, debris bed coolability, challenges to reactor vessel integrity, core-concrete attack, fission product release, transport and deposition, etc.
He was a member of the EPRI (industry) team that assessed the reactor behavior following the Three Mile Island - Unit 2 accident and he was also one of the Industry Representatives in the U.S. delegation to IAEA /Vienna to evaluate the Russian interpretation of the Chernobyl Unit 4 accident. In addition he has served on NRC review panels to evaluate ongoing research. As a result of his experience, Dr. Henry was chosen to author the EPRI Technical Basis Report for supporting the development of Severe Accident Management Guidelines for all four U.S. reactor types.
Dr. Henry’s areas of expertise are severe accidents, two-phase flow and boiling heat transfer as well as waterhammer phenomena. In particular, he, along with Dr. Fauske, authored the Henry-Fauske two-phase critical flow model which has been used to analyze the blowdown behaviors for nuclear plants in all of the nuclear power countries.
Previously Dr. Henry held a number of responsible research and development positions at Argonne National Laboratory (ANL) from 1969 to 1980 including Associate Director of the Reactor Analysis and Safety Division.
Dr. Henry has published more than 150 articles in the areas of nuclear safety and engineering and has authored, or co-authored six U.S. patents as well as a book on the accident management lessons from the TMI-2 accident. He is a member of the American Nuclear Society and in 1985, he received the Tommy Thompson Award: the highest honor the American Nuclear Society gives in the field of reactor safety. Dr. Henry also received an Award for Outstanding Engineering Accomplishment from the College of Engineering, University of Notre Dame, in 1990.
