Zachry Nuclear Engineering provides
engineering analysis services including thermal
hydraulic, radiological, chemical, reactor
physics/core design and safety evaluations.
We are a leading developer of software used
in more than 90% of the U.S. nuclear fleet,
including GOTHIC™*, Proto-FLO™, Proto-HX™,
Proto-HVAC™, Proto- Sprinkler™, CentralStor™
and RADTRAD-NAI™.
Zachry developed and maintains the industry-
standard GOTHIC™ analysis code, utilized for
critical operating plant assessments including
analyses of containments, fuel pools, reactors,
primary and secondary piping/systems and
buildings/compartments. We are pioneers
in the systematic integrated approach to
fluid system analyses including: system
performance prediction; component capability
analyses; licensing/design basis requirements;
component in-service-testing acceptance
criteria; maintenance periodicity; and 89-13
requirements. Zachry also investigates system
and equipment performance, evaluates
improvement options, and verifies the
capability of plant systems under normal and
accident conditions.
Combining the most experienced people
with the best tools available creates optimal
solutions. Contact Zachry today to find out
how we can support your analysis needs.
