ORAM Streamlined Configuration Control type tool

4 ORAM (Streamlined Configuration Control type tool) 

Various operational applications of PSA related methods have been broadly accepted in commercial Nuclear Power Plants. One of the complex, but interesting and useful applications, from the utility perspective, is the use of PSA for configuration control. Such an application is typically called Risk Monitors. 

The recent interest in Risk Monitoring for power operation has a different background in Europe and in the USA. In the USA the prime driving force behind Risk Monitoring appears to be both the financial interest (to reduce the cost of operation) and the safety interest. The most visible potential applications are Configuration control. Maintenance-rule-related issues, and Technical Specifications. In Europe, as a centerpiece of discussion between utilities and regulators, the Risk Monitors are more safety-focused and attention is placed on risk follow-up. 

EPRI sponsored development of ORAM software package which consists of Probabilistic Shutdown Safety Assessment (PSSA) and Risk Management Guidelines (RGM), both of which are used to identify and control safety in shutdown operating mode. The stated objectives of ORAM is to  

The ORAM software could be integrated with various outage scheduling software packages for automatic input of data to outage schedules.
