GOTHIC is a versatile software package that allows a user to
build models for solving complex thermal hydraulics problems involving multiphase
flow of steam, water drops, liquid water and non-condensing gases with interface
heat and mass transport.
Fluid regions are represented by lumped parameter nodes and 3D grids.
Models for heat sinks allow heat exchange between the fluid and solid structures.
Models for equipment such as pumps, fans, valves and heat exchangers can be
assigned to hydraulic connections between fluid regions.
Other models available in GOTHIC include radionuclide source, decay and
transport, hydrogen burn, and sediment transport in the liquid phase.
Models can be built easily and accurately in a graphical interface that
performs extensive input error checking.
The graphical interface can be used to display results in both time and
vector/contour graphs. Data files can be written to produce more elaborate
displays such as those presented for the
GOTHIC includes special features for modeling
nuclear power plant containments, auxiliary buildings and plant equipment.
NAI supports the code for regulated safety analysis and other plant design
and operation issues.
GOTHIC is developed and maintained under NAI's QA program conforming
to 10CFR50, Appendix B requirements.
GOTHIC incorporates technology developed for the electric
power industry under sponsorship of EPRI, the Electric Power Research Institute.

CentralStorTM from NAI
is a new system for on-line managed data storage. It allows an enterprise to
centralize, organize, share and secure valuable documents in an electronic
archive. More than a traditional backup system, CentralStor allows users to
decide which data to archive and provides a framework for fast and easy
retrieval of stored documents.

NAI's version of RADTRAD, a code that was developed by the NRC for
radiological dose analysis. Our code is suitable for dose analysis under the
new Alternative Source Term (AST) Guidelines (NUREG-1465) as well as the
TID-14844 Guidelines. The code is available as an installable product or as a
web-based version maintained by NAI.
