A prototype real-time process monitoring emergency
classification expert system, RT/EM-CLASS, has been developed
for use at the Trojan Nuclear Power Plant. This knowledge-based
system features the integration of electronically sensed plant
data with the menu selection data representation of its
predecessor, EM-CLASS. This prototype demonstrates the
techniques required to acquire plant process data from another
computer and use that data in an expert system to determine the
proper Emergency Action Level.
Several benefits are realized by the RT/EM-CLASS application.
These include:
The resources required to make a classification are
reduced thereby freeing the responsible person to devote
time to other important tasks.
The classification may be completed more often and with
better data than the current system allows.
The human user is less likely to make an erroneous
Emergency Action Level classification.
Prototype implementation required resolution of an efficiency
problem of relating plant process data to the expert system data
forms. This was achieved through the development of multi-conditional
rules that significantly reduce the size of the rule set.
The development of RT/EM-CLASS presents a methodology
for building knowledge based applications that perform nonintrusive
real-time monitoring of dynamic systems. This
methodology features
Use of existing analytical and Al tools where possible
Monitoring of a dynamic system
Non-intrusive acquisition of data from the system
This technology might be applied to portions of the nuclear
engineering design process (control rod programming in Boiling
Water Reactors, for example) to emulate the guidance and
activities of an expert. A substantial portion of the effort by the
expert engineer involves preparation of the code input, running the
computer code, analyzing the results, and based on the results,
deciding what case to submit next. A suitably designed expert
system could act in the place of the engineer in this dynamic
design process.
This methodology has been tested against the 1988 emergency
exercise at the Trojan Nuclear Power Plant. / Graduation date: 1992
