Tom Nirider
Proven Experience
Tom Nirider has thirty-five plus years of progressive experience in the nuclear industry with expertise in Nuclear Safety, Criticality Safety Program Management, Documented Safety Analysis (DSA) development, Technical Safety Requirements development, Criticality Safety Engineering, Chemical Flowsheet Management, Unreviewed Safety Questions (USQ), and Nuclear Operations. He is a retired subject matter expert and program manager in nuclear criticality safety. He has supported nuclear operations and safety basis development for several Hazard Category 2 DOE Nuclear Facilities, including the Hanford Plutonium Finishing Plant, Hanford Tank Farms Operations, Waste Isolation Pilot Project, Pacific Northwest National Laboratory (PNNL), and the Tank Waste Treatment and Immobilization Project including; Tank-Side Cesium Removal, Direct Feed Low-Activity Waste Facility, the High-Level Waste Vitrification Facility and the Tank Farms Advanced Modular Pretreatment System.
Mr. Nirider has a B.S. in Physics and Mathematics from Eastern Washington University and an M.S. in Nuclear Physics from the University of Washington.
Sustainable Results
Mr. Nirider was the Criticality Safety Program Manager and Nuclear Safety Specialist for DOE Richland and the Office of River Protection, responsible for nuclear and criticality safety technical and regulatory issues, including USQ, PISA, JCO, and approval of the Preliminary Documented Safety Analysis supporting construction and eventual operation of the Hanford Tank Waste Treatment and Immobilization Plant Project (WTP), including the Pretreatment Facility and High-Level Waste Processing Facility. He managed the DOE-ORP Criticality Safety Program to construct the Hazard Category 2 Hanford Tank Waste Treatment and Immobilization Plant Project and the Hazard Category 2 Tank Farms Operations.
As the Criticality Safety Manager/Senior Nuclear Safety Specialist at Bechtel, he managed the Bechtel WTP criticality safety program. In this capacity, he developed program safety documentation and procedures to support the startup of the Direct Feed Low-Activity Waste vitrification facility, supported safety analysis, design, and construction of the Hazard Category 2 High-Level Waste Vitrification Facility, developed safety basis documentation, including criticality analysis of fissile-bearing waste retrievals from Tank Farms for subsequent processing in the High-Level and Low-Activity Waste Vitrification Facilities, developed and implemented the criticality safety program for the Waste Treatment Plant Facilities, and supported resolution of complex technical issues involving fissionable material waste processing.
