Subject:
NRC Region I Inspection Report Nos. 50-410/91-81, 50-220/91-19 and
50-410/91-19
During the period of September
3-16, 1991,
a special Restart
Readiness
Assessment
Team
(RRAT) conducted
an inspection of your corrective actions and readiness
to restart Nine Mile
Point 2 following the August 13, 1991 event.
This event, which resulted in the declaration of
a Site Area Emergency, involved a loss of control room indications and'an automatic reactor trip. The initiating events were the failure of a main transformer and a loss of five non-safety
Uninterruptible Power Supplies (UPS).
The inspection
team
focussed
on the areas of (1) personnel
perform'ance,
(2) maintenance
program effectiveness,
and (3) organizational effectiveness.
The inspection was conducted
to
support a NRC restart decision as a result of the incident inspection activities by the NRC's
Augmented Inspection Team (AIT)and the Incident Investigation Team (IIT). An inspection of
(EP) activities, which started on August 13, 1991, was also conducted
during this period.
This special
EP inspection
examined
the actions
taken by emergency
response organization personnel in response
to the August 13, 1991 events.
The results of the RRAT inspection, as detailed in Enclosure
1 (Report No. 50-410/91-81), were
discussed with you in the RRAT exit meeting on September
16, 1991.
The team found that the
enhanced
training on UPS operations;
the progress in maintenance program effectiveness;
and
the corrective actions for the problems identified in the area of organizational
effectiveness
during the event were good. The team concluded that the licensee had taken sufficient corrective
actions based on their review for problems identified during the event to support safe restart of
the unit.
