PRA is critical to the safe operation of complex, potentially hazardous facilities.
JENSEN HUGHES’ staff are highly experienced in developing PRA methods and software tools and applying these resources in risk assessments for many clients in the industry and government. This experience began in the early 1970s with the first comprehensive nuclear power plant PRA (the “Reactor Safety Study,” WASH-1400). Since then, our staff members have established and maintained a dominant role in the use of risk and reliability techniques to enhance the safety and operational performance of complex facilities, such as nuclear power plants, chemical process facilities, and hazardous material storage facilities.
JENSEN HUGHES’ team is leading the industry trend toward developing “living” PRAs and applying these PRA results within the framework of real-world decision-making processes. Our PRA analysts and engineers analyze product or system risk characteristics through the entire life cycle, from concept phase through system operations. We use fully-tested and proven PRA tools and techniques along with extensive libraries of historical operations and failure data to quantitatively derive the probability of occurrence of highly undesirable events or accidents. We are an established worldwide industry leader in risk and reliability assessments and risk-informed technologies.
Our team of 30+ skilled professionals has collective experience surpassing 500 years; over 400 years in risk assessment. JENSEN HUGHES has additional staff in nuclear licensing and engineering analyses, among other areas, needed to support full scope of the PRA and risk-informed applications. JENSEN HUGHES engineers are adept with a number of PRA tools and models including event tree analysis, fault tree analysis, human reliability analysis, fire risk modeling, risk quantification and results presentation (e.g., CAFTA, SAPHIRE, FRANX, EPRI HRA Calculator).
For over 30 years our staff has supported nuclear power plants worldwide in development and maintenance of their risk assessment models, addressing:
- Internal Events PRA; Levels I, II and III
- Internal Fire and Floods PRA
- Low-power and Shutdown Risk Analysis
