NORTHERN STATES POWER SUMMARY REPORT INSERVICE INSPECTION MONTICELLO 1991

1. Summary

The 15th Monticello refueling outage began 3-31-91 and ended 5-31-91.

Visual and nondestructive examinations were performed by NSP, Lambert Macgill and Thomas, GE, and ABB/TRC personnel. Copies of examination procedures, personnel certifications and equipment records are available at NSP.

Results of the examination indicates that the integrity of the plant systems has been maintained.

Certain reactor pressure vessel welds were examined with an automated UT system. A similar examination was performed in 1989. Results of these examinations indicate that the reactor pressure vessel welds are acceptable.

In reference to the NRC letter received August 28, 1991 from Thomas Ippolito on "Implementation of Unresolved Safety Issue A-10, BWR Nozzle Cracking" and NSP's submittal of April 22, 1985 giving supplemental information related to the inservice inspection examination summary for refueling outage No. 10, the following information relating to the feedwater sparger inspection performed during the 1991 Refuel and Maintenance outage is provided for the use of the NRC staff.

The total number of startup cycles since the last feedwater nozzle surface inspection done during the 1989 refueling outage is 6. The total number of shutdown cycles since the 1989 outage is also 6.

An on line feedwater nozzle thermal sleeve leak detection system has been used to monitor feedwater nozzle thermal sleeve bypass flow. This system indicates that there is no significant bypass flow and there is no increasing trend on any of the nozzles.

REPORT OF IN VESSEL VISUAL EXAMINATION RESULTS PERFORMED FOR

NORTHERN STATES POWER COMPANY MONTICELLO GENERATING STATION

1991 OUTAGE

EXAMINATION SUMMARY

During the period of April 25 through April 28, 1991, GE Nuclear Energy personnel performed In Vessel Visual Inspections on internal components of the Monticello RPV. This section details the techniques used and the results of the inspections.

Examination Techniques:

The examinations were performed using remote CCTV equipment, underwater lighting, camera mounted lighting, and VHS videotape recording equipment. The camera was hand held. System resolution was verified using an 18% neutral gray card with both a 1/32" line and a 1 mil. wire. Resolution was verified on each videotape recorded.

Examination Results:

There was no evidence of degradation of the RPV internal components detected during this examination. No relevant indications were detected.

Nonrelevant Indications:

There were areas that contained indications that were proven to be nonrelevant by changing the lighting and angle of the camera. Most areas were proven to be undercut or as welded conditions. The manway covers were partly obscured by sediment on the shroud. The shroud shelf welds were only accessible bewteen the jet pumps.
