HISTORY AND EXPERIENCE DEVELOPING PRA METHODS
Our Risk-Informed Engineering (RIE) staff has a long history of
experience in developing PRA methods and software tools and
applying these resources in risk assessments for many clients in the
industry and government.
Starting in the early 1970s with the first comprehensive nuclear
power plant PRA (the “Reactor Safety Study,” WASH-1400), 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
Hazardous Material Storage Facilities.
Our team is leading the industry trend toward developing “living”
PRAs and applying these PRA results within the framework of realworld 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 fullytested 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 skilled professionals
has collective experience surpassing
500 years, with more than 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.
INTERNAL EVENTS PRA
For over 30 years our staff has supported nuclear power
plants worldwide in development and maintenance of their risk
assessment models.

EXTERNAL HAZARDS PRA
JENSEN HUGHES has teamed with ARES Corporation and
other partners to provide full service capability and capacity to
address all external hazards, including seismic, external flooding,
and high wind. Our experienced team can provide utilities with
quality solutions to emerging needs and requirements. These
include responding to Near-Term Task Force Recommendations,
requirements of Generic Issue-199, post-Fukushima requests
meeting NRC’s Regulatory Guideline 1.200, Rev. 2 expectations, and
the ASME/ANS PRA Standard.
