RiskSpectrum HRA

Standardise your Human Reliability Analysis

RiskSpectrum HRA is a software tool for evaluating and quantifying human failure events (HFE), meeting requirements of ASME PSA Standard and NRC HRA Good Practices.

RiskSpectrum HRA help you standardize your HRA analysis process:
  • Performing and documenting the necessary HRA steps
  • Using the appropriate HRA method
  • Quantify the HFE´s human error probabilities (HEP)

RiskSpectrum HRA includes a number of commonly-used HRA methods, such as THERP, ASEP, HCR/ORE, SPAR-H and HEART, etc.

For each Human Failure Event (HFE) analysed, multiple methods can be used for quantifying the HFE probability and the different results can be compared.

 

Software In Action

 

Pre-initiator Human Failure Events

Pre-initiators consist of those actions associated with maintenance and testing (e.g., prior to the initiation of an accident) that degrade system availability.
The pre-initiator HFE calculation methods available in RiskSpectrum HRA are:

  • THERP
  • ASEP
  • HEART
  • Screen Value

 

 

 

Post-initiator Human Failure Events

Human failure events that represent the impact of human errors committed during actions performed in response to an accident
The post-initiator HFE calculation methods available in RiskSpectrum HRA are:

  • THERP
  • HCR/ORE + THERP
  • ASEP
  • HEART
  • SPAR-H
  • Screen Value

 

Integration with RiskSpectrum PSA

RiskSpectrum HRA version 1.2 was released in February 2025. It includes a number of great new features. 

  • Import from and synchronise with RiskSpectrum PSA – compare the records in the HRA database with the corresponding events in the PSA model
  • Extend the ID length to 50 characters in RiskSpectrum HRA to support long ID in RiskSpectrum PSA 1.5.1 and later versions.

  • The RiskSpectrum HRA interface support comparing the records in the RiskSpectrum HRA database with the corresponding events in the RiskSpectrum PSA model.
