Nuclear plant accident risk evaluation monitor
Scientech's Safety Monitor™ is a Windows-based interactive
tool that allows plant personnel to evaluate the effects of
changes in plant configuration on accident risk. The system
operates as a multi-user system, with various features to
support work scheduling, operations, PRA, and Maintenance
Rule personnel.
The software is designed to allow its use by personnel with little
or no PRA training. Using a high speed PRA model of the plant,
the software performs risk calculations (core damage frequency,
large early release frequency and shutdown boiling frequency)
for each unique plant configuration. Besides its use as a tool to
plan safe plant operations, it can record actual risk history and
component/train unavailability over time.
In a multi-user network installation, the Safety Monitor™ can be
used by almost anyone at the plant. Typical users include
maintenance and outage-scheduling groups, operations support
groups, Shift Technical Advisors, Maintenance Rule Compliance
personnel, and plant management. PRA personnel can also use
the software to provide more specialized risk evaluations of
unusual plant conditions.
