RISK & RELIABILITY SOFTWARE

RiskSpectrum PSA is a creative software that you can use to edit, debug, test and deploy a PSA model. In addition to what most standard fault tree and event tree editor provide, RiskSpectrum PSA includes tools for model completion, MCS tracing, scripting based updating, and many more features to enhance the PSA model development and maintenance process.

RiskSpectrum is considered the nuclear industry standard in many countries and is licensed for use at 60% of commercial nuclear power plant operators World-Wide.

RiskSpectrum ModelBuilder is a unique risk modeling platform that helps designers and operators of safety-critical systems ensure uninterrupted, safe, and reliable operations by transforming the way they conduct risk assessments.

With RiskSpectrum HRA, you can run consistent Human Reliability Analysis (HRA) to produce high-quality, repeatable results with solid traceability and documentation.
Guiding you step by step, RiskSpectrum HRA helps you standardise your process for quantifying and reviewing human error probabilities for your defined human failure events. It offers multiple well-known methods for quantifying probabilities, such as:

• THERP
• ASEP
• HCR/ORE
• SPAR-H
• HEART

RiskSpectrum RiskWatcher delivers real-time risk intelligence to inform vital operational decisions. Optimised to work with PSA models created in RiskSpectrum PSA, it helps assess and manage risk exposure at vital assets like nuclear power stations and offshore drilling rigs.

R-DAT is a Bayesian data analysis package designed specifically for risk analysts and reliability engineers. It helps you develop and update system-specific reliability parameter estimates. R-DAT's powerful, flexible and user-friendly environment lets you store and organise many types of reliability data and related information.

• Build generic and system-specific failure rate distributions using powerful Bayesian algorithms
• Develop functional, structural or any other type of system decomposition at any level of detail
• View results in easy-to-understand graphical and tabular displays

RiskSpectrum SDP is a tool designed to support the Significance Determination Process as defined by the US Nuclear Regulatory Commission. The tool includes guidance and forms where findings and events can be reported and ranked regarding risk significance. It is linked to your PSA models and the findings and events can be assessed using the full scope risk model in RiskSpectrum PSA.
