ABSTRACT
Safety on the management for a nuclear research reactor
involves a "good dependability* management" of the
activities, such as: reliability, availability, maintainability
and maintenance support. In order to evaluate the safety management
aspects intended to be applied at a research reactor management, the
performance dependability indicators and their impact over the availability and
reactor safety have to be established. The document ISO 9000-4/IEC 300 –1“Dependability
Management” (1995), describes five internationally agreed indicators of
the reactor equipment dependability, each of them can be used for corrective
maintenance or for preventive maintenance, such as: I1
- equipment Maintenance Frequency; I2 - equipment
Maintenance Effort; I3-
equipment Maintenance Downtime Factor; I4 - equipment
Maintenance Contribution to the System Function Downtime Factor; I5
- equipment Maintenance Contribution to the reactor Capability Loss Factor. The
paper presents an evaluation of those 5 mentioned indicators with referring
only at the primary circuit of the INR's TRIGA
research reactor and conclusion. The analyzed period was stated between 1994-1999. It is to be noted that this type of
analyze is performed for the first time for a research reactor.
