case, this is identified as an unresolved item, URI 50-400/9 06-01, USQ Determination Related to Cycle 6 Reload.
Conclusion For 19 safety evaluation forms reviewed by the inspect r, the licensee's determinations that a
USQD was not required were cons dered correct, although the bases for those determinations were ty cally weak.
Similarly, the bases for USQDs were weak in some c ses.
The inspector's findings in this regard were consistent with the indings descr ibed in HNAS98-015.
For 15 of 16 USQDs reviewed by the insp ctor, the licensee's determination that the corresponding ch e
did not involve a USQ were considered correct.
An unresolved item opened with respect to the Unreviewed Safety Question Determina on escribed in the safety evaluation for the Cycle 6 Reload.

37661 The NRC identified to the c
see on January 27, 1998 that there could otentially be loose boltin material in the containment sumps.
The icensee initiated CR 98-0 95 to investigate and address this condition.
The inspector eviewed the root cause investigation.
Observation and Findi s
A short term operabi ity determination was performed and was documented in ESR 98-00042.
C Inspection Report 50-400/98-01, Section E1.2, Containment Sump ncerns, reviewed the short term operability determination.
e licensee found that the bolting material was a
bracket for for ign material exclusion (FME) covers that were put in place for the lant construction process.
They were not shown on any drawings and therefore were not permanent plant equipment.
They were not removed at the end of plant construction in 1986 as they should have been.
Th licensee found that during refueling outage 7 (RF07), workers and engi ers who were working on containment sump leaking problems observe a bracket on the sump suction pipe that was loose.
An engineer remov the portion of the bracket that was loose.
The remaining brac ts were haraner tested and found to still be soundly attached to the ipe with tack welds.
The licensee concluded in the ESR 98-00042 t t the sumps were oper'able with the parts left in place.
The NRC ncluded that the operability evaluation was adequate.
The licensee performed a root cause evaluation for CR 98-00295.
The cause of the brackets being left in the sump was that they were not recognized as a deviation from design during system and area turnovers during construction walkdowns in 1986.
The reason they were left in the
