15. Operational Safety
The OEF program should be effective. Effectiveness appears through root cause
investigations, processing of an external OEF experience, OEF information meetings, and
through training sessions involving OEF information. Important issues are number of
significant events, repeated events, events that appear similar to known external
experiences, and events that are shared with the external nuclear community.
Procedures are provided for the OEF program, including: a description of the OEF
program, clearly defined responsibilities, precise guidance on how to process OEF
information, and some means of status reporting. This activity is preferably co‐ordinated
by one individual, and specific guidance on it is given in written procedures.
The OEF procedures have a systematic method for documenting various in‐house events
and the type of events being documented include both significant and non‐consequential
events. The shift operating logs for events are considered for investigation. The screening
process of in‐house events includes precursor events. The root‐cause investigation process
is carried out by trained staff members experienced with various root‐cause techniques.
The safety performance of the plant is monitored through a process including specific
safety performance indicators, such as, the number and severity of significant events, the
number of outstanding work orders, and the duration of unavailability of safety systems.
They are monitored, trended and analyzed by a group within the Technical Support Section
of the plant. Safety performance indicators are routinely reported to and reviewed by the
plant safety review group or Nuclear Safety Committee. The plant manager, department
managers and corporate management are routinely updated on the safety performance
