RiskSpectrum® RiskWatcher

RiskSpectrum RiskWatcher is a risk monitor software for calculating current risk at nuclear power plants.

RiskSpectrum RiskWatcher calculates risk based on a PSA model and provides for means to take into account plant operating mode, equipment outages, system configurations, periodic tests, environmental factors, etc. It is optimised to work together with PSA-models created using RiskSpectrum PSA and therefore the ideal risk monitor software for RiskSpectrum PSA users.

Normal plant equipment IDs and descriptions and a minimum of PSA related terms are used so the user need not understand a PSA model or PSA jargon. One of the key features of RiskWatcher is that all data is edited in the model in RiskSpectrum PSA and no changes need to be introduced "afterwards" in the separate RiskWatcher model. This principle simplifies the process of going from a living PSA baseline model to a functional risk monitor model and will greatly simplify continuous update work - i.e. maintaining a true living PSA model - when the system is in operation.

RiskSpectrum FMEA (Failure Mode and Effect Analysis) helps you analyse, document and quality assure the input to your fault tree model.

FMEA is an important tool which facilitates the quality assurance process by providing a readily traceable means of documenting important information for components (modelling assumptions etc.,) when performing a risk and availability analysis. Another advantage with an FMEA is that you get a structured list of the effects the postulated failures may have upon the system being analysed.

At RELCON, we realised that it would be advantageous if some data, for example failure data, could be automatically exported from the FMEA database into a RiskSpectrum FT or PSA Professional database. Setting this is as one of the objectives, we have developed RiskSpectrum® FMEA.

RiskSpectrum FMEA not only helps you analyse and document failures in the system being analysed, it also automatically generates basic events and parameters which can be directly imported into your RiskSpectrum FT or PSA fault tree models.
