R-DAT
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
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.

RSAT 3.4.5 Released (RiskSpectrum PSA 1.4.0/RSAT 3.4.5) (15 June 2020)
RSAT 3.4.5 resolves two issues for MSC analysis cases (merging of MCS lists) in presence of success modules: MCS BDD quantification and cutset minimization.
Success modules are now quantified correctly also when an MCS BDD is built from a demodularized MCS list containing several success modules which depend on the failed part. Improved identification of success modules leads to a more efficient minimization.
Download RSAT 3.4.5
This RSAT version also includes the novel quantification method ‘Initiator and All Barriers’ (I&AB) module as an add-on. This method allows to take repairs of components into account in a computationally efficient way, scaling to real-life PSA models. -
RSAT 3.4.4 Released (PSA 1.4.0/RSAT 3.4.4) (28 November 2019)
A RSAT patch release to RiskSpectrum PSA 1.4.0 is now available. The patch updates RSAT only.
RSAT 3.4.4 resolves the identified issue regarding special cases of MUX quantification. The issue relates to partitioning of the MCS list into groups (MUX).
The most likely effect of the issue is triggered by analyses where the MCS list contains only one event from a MUX group represented in the MCS list. This could cause the algorithm to incorrectly throw an error message "ERROR: There are too many MCUB groups as a consequence of too many MUX events." This will stop the calculation. Alternatively, it could cause an unexpected termination of RSAT.
There is a very rare situation where the issue can cause that MCSs are assigned to the wrong MUX group. This would have the effect that MCUB would apply between MCSs, which should be summed up. The impact of this very rare situation would hence be a slight underestimation of the combination. In normal cases where the conditional probability is low (frequency event excluded from cut set) this has a negligible impact. All regression tests performed by LR has shown no difference in results due to this issue.

RiskSpectrum PSA 1.3.2 (RSAT 3.4.0) Released with Limbr (28 November 2019)
As part of the transition to the new Limbr licensing system, we have now released RiskSpectrum PSA 1.3.2 using Limbr. This is to help clients to transfer from the HASP protection to the Limbr licensing.
The functionality in RiskSpectrum PSA 1.3.2 is exactly the same as the previous release if the maintenance module is installed, including MCS BDD. The RSAT version installed is then RSAT 3.4.0.
The released version with Limbr is the same combination: PSA 1.3.2 and RSAT 3.4.0.
