For more than four decades, Zachry Group has provided nuclear engineering, design
and project management services, with extensive PWR and BWR experience, to the
majority of the U.S. commercial fleet. The technical capabilities of Zachry’s nuclear
team assist plant owners in support of a wide variety of operational, regulatory,
maintenance, and upgrade needs.
Headquartered in San Antonio, Texas,
Zachry Group has dedicated offices
specializing in nuclear services in
Stonington, CT; Charlotte and Cary,
NC; Richland, WA; Idaho Falls, ID and
Chicago, IL. They offer mechanical,
electrical, controls and civil/
structural engineering and design
professionals who are knowledgeable
in power plant systems; engineering
analysis and modification package
development; and startup of power
plant systems and components.
Zachry is a qualified nuclear QA
supplier. All services are performed
in accordance with its Nuclear
Quality Program, which complies
with 10CFR50 Appendix B and
ASME NQA-1 (1994), and has been
successfully audited by NUPIC.
Zachry’s full range of engineering
and design services are backed
by years of nuclear power plant
system experience and practical
application of time-tested solutions.
This includes assembling a fit-for-
purpose team for the job, taking
into account employees’ education,
skills and expertise. Zachry uses
industry-recognized design tools
and processes, including an in-
house Failure Modes and Effects
Analysis (FMEA) procedure that
fully evaluates proposed system
modifications to ensure they will
operate effectively and without error.
As part of Zachry’s nuclear services
group, Numerical Applications
Division (formally NAI) consistently
provides the industry with state-
of-the-art modeling techniques
and approaches for containment
response and area heat-up during
both design and beyond design
basis events. This division of
Zachry provides a wide spectrum
of engineering analysis services
including thermal hydraulic,
radiological, chemical and safety
analysis, and is the leading developer
of nuclear software including Proto-
FLO™, Proto-HX™, Proto-HVAC™,
Proto- Sprinkler™, CentralStor™,
RADTRAD-NAI™ , RETRAN*, VIPRE*
and GOTHIC™* with the most
knowledge to apply the codes.
GOTHIC™, as applied by Numerical
Applications, has become the
industry standard for containment
modeling and analysis, and has been
extensively utilized in operating
and new plant licensing activities.
This team also has considerable
experience using industry-standard
software tools such as RELAP.
The Zachry team delivers high-
quality design with the utmost
care and strict adherence to safety
and regulatory requirements.
With a focus on cost-effective
operations, Zachry engineers
investigate plant performance
problems, assess compliance to
code and regulatory requirements,
perform feasibility studies, develop
conceptual designs, evaluate the
cost and effectiveness of plant
upgrades, and prepare detailed
plant design changes including
specifications and drawings for plant
construction and modifications.
