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.

RSRW has two main
groups of views, Operator and Planning.
In the Operator views
group, current risk levels, AOT, Defence-in-Depth, risk graphs,
components out of service and system configurations can be
studied on the Operators Screen. There are also views for
obtaining advice on which components that are particularly
important in the current configuration or the configuration you
are about to enter.
The Planning view
group include views that are relevant when planning ahead and
for risk-follow-up. Here it is possible to compare different
scenario with regard to risk and Defence-in-Depth. |
