PARCS
PARCS code is a three-dimensional (3D) reactor-core simulator computer code that solves the time-dependent two-group neutron diffusion equation in three-dimensional Cartesian geometry using nodal methods to obtain the transient neutron flux distribution. The code may be used in the analysis of reactivity-initiated accidents in light-water reactors where spatial effects may be important. It may be run in the stand-alone mode or coupled to other thermal-hydraulic codes, such as PARCS.
PibTool
PibTool is a software development tool used to generate source code used to create platform independent binary (PIB) files. The current version will create Java classes, JavaBean classes, Documentation, and Fortran routines from the common PIB file specification.
QuARTIC
QuARTIC® is a software tool that automates the propagation of facility design information all the way through to the completion of a qualified code input model and companion calculation notebook, which has been verified and referenced to the design data. This provides a unique method of preparing quality controlled input models and documentation, which aids users in achieving NQA-1 compliance.
RELAP5
RELAP5 is an Information Systems Laboratories, Inc. (ISL), updated, maintained, and, in part, developed thermal-hydraulic computer code that models best-estimate transient and small- and large-break type accident simulation of postulated accidents in light water reactor coolant systems. The code models the coupled behavior of the reactor-coolant system and the core for loss-of-coolant accidents and operational transients, such as anticipated transient without SCRAM, loss of offsite power, loss of feedwater, and loss of flow, through a one-dimensional, two-fluid model consisting of steam and water. The U.S. Nuclear Regulatory Commission (NRC) recognizes the code for the aforementioned analysis.
RFView®
RFView®, a high-fidelity modelling and simulation tool, is an electromagnetic physics solver that uses publicly available Digital Elevation Maps (DEMs) along with standard physics-based ray tracing and propagation to produce simulated radar returns. It employs well-known and accepted principles of physics to calculate those returns. The simulation environment is built on ISL’s industry-leading RF phenomenology engine. Uses of the model include system analysis, test planning, high-fidelity synthetic data generation, signal processing algorithm development, training, strategy development, and conduct-of-operations assessment. The model provides characterization of target returns, direct path signal, ground scattered signal (clutter for radar), direct path signals from interferers, and ground scattered interference signals (hot clutter, splatter, or terrain-scattered interference).

RFView®—RTEMES
RFView®—Hardware in the Loop (HWIL) incorporates ISL’s RFView®, a high-fidelity modelling and simulation tool, with its Real-Time Electromagnetic Environmental Simulator™ (RTEMES™), which converts any RF signal from digital to analog without need for the waveform model. RFView® is an electromagnetic physics solver that uses publicly available Digital Elevation Maps (DEMs) along with standard physics-based ray tracing and propagation to produce simulated radar returns. It employs well-known and accepted principles of physics to calculate those returns. The simulation environment is built on ISL’s industry-leading RF phenomenology engine. Uses of the model include system analysis, test planning, high-fidelity synthetic data generation, signal processing algorithm development, training, strategy development, and conduct-of-operations assessment. The model provides characterization of target returns, direct path signal, ground scattered signal (clutter for radar), direct path signals from interferers, and ground scattered interference signals (hot clutter, splatter, or terrain-scattered interference). RTEMES™ collects RF waveforms, converts them from digital to analog signals, and simulates—through RFView®—terrain, clutter, and defensive systems, among other attributes, of any place in the world, including those that are among the most highly contested and denied environments in the world. RFView®—HWIL accordingly allows flight testing of real-world radar systems in real-world conditions that would otherwise be impossible or unaffordable, and it does so without need to reveal waveforms. RFView®—HWIL’s novel high-fidelity emulator thus allows for real-world system testing of GMTI, AMTI, SAR radars and EW systems; ground and airborne radars; and single and multichannel systems without ever leaving the laboratory. The data in this version of RFView®—HWIL is precomputed.
RFView®—SIM
Advanced, site-specific radio frequency (RF) simulation & analysis tool offering highly accurate characterization of complex RF environments. Used for system analysis, test planning, high-fidelity synthetic data generation, and signal processing algorithm development.
RFView®—Training
High-fidelity radar & electronic warfare training capability.
R-Matrix
Matrix Version 2,0 provides full requirements traceability through all lifecycle phases of a project and provides IEEE, CMMI, and NQA-1 project management standards compliance.
SNAP
SNAP is an Information Systems Laboratories, Inc. (ISL) suite of integrated applications designed to simplify the process of performing engineering analysis for nuclear facilities. SNAP is built on the Common Application Framework for Engineering Analysis (CAFEAN), which provides a highly flexible framework for creating and editing input for engineering analysis codes as well as extensive functionality for submitting, monitoring, and interacting with several analysis codes, such as RELAP, TRACE, and PARCS, among others. SNAP, moreover, creates a visual depiction of the analyses conducted through those various codes that can be used to illustrate the real-time consequences of various operating and safety scenarios. It is a robust digital engineering tool that allows analysts the capacity to evaluate and understand the consequences of design, operating, and safety analysis decisions. The U.S. Nuclear Regulatory Commission (NRC) recognizes the SNAP code for the aforementioned analysis.
SNAP RELAP Common Plugin
The SNAP Common RELAP Plugin is a portion of all RELAP-based plugins code that is common to and owned exclusively by ISL. The code is a building block of all RELAP-based plugins and is present in all such plugins, even those developed for specific customer use. ISL asserts title only to the Common RELAP Plugin portion of any plugin developed for specific customer use.
SNAP Feature Set—Universal Suite
The SNAP Feature Set—Universal Suite is a suite of SNAP plugins commonly supplied as part of SNAP to all users. The Universal Suite provides additional functionality.
SNAP Feature Set—Government Suite
The SNAP Feature Set—Government Suite are suites of SNAP plugins available to most users that were developed in collaboration with the U.S. Government. The Government Suite provide still more functionality.
TRACE
TRACE is a modernized thermal-hydraulics code designed to consolidate and extend the capabilities of the legacy safety codes, TRAC-P, TRAC-B, and RELAP. It is able to analyze large and small break loss-of-coolant-accidents (LOCAs) and system transients in both pressurized- and boiling-water reactors (PWRs and BWRs). The capability exists to model thermal hydraulic phenomena in both one-dimensional (1-D) and three-dimensional (3-D) space. The TRACE code is the flagship thermal-hydraulics analysis tool.
