10. Abstract of Examinations The Inservice Examination of selected Class I and II components and piping systems of Florida Power and Light Company's St.Lucie Plant, Unit 2, was performed during the refueling outage which began on February 1, 1989. This was the second and last outage scheduled for the second inspection period of the First 10-year Interval (Program B).

The components and piping systems examined were selected per the First Ten Year Inspection Plan, which was prepared per the requirements of Section XI of the ASME Code, 1980 Edition, through Winter of 1980 addenda.

Manual ultrasonic, liquid penetrant, magnetic particle, and visual nondestructive techniques were used in the examination of the selected components, piping systems, and their supports.

See attached Summary Tables for complete examination results.

Mechanized ultrasonic techniques were utilized in the examination of the reactor vessel. The examinations were conducted by Southwest Research Institute.

Radiography was used in the examination of the 2B1 Reactor Coolant Pump. Duke Engineering & Services Inc. performed the examinations.

Eddy current examinations were conducted by Combustion Engineer-ing from February 2, 1989 through March 1, 1989 on 2A and 2B Steam Generators. 8203 tubes in steam generator 2A and 8256 tubes in steam generator 2B were examined. See the attached NIS-BB report for the summary of examination results.

Snubber functional testing and visual examinations were conducted in accordance with St. Lucie Unit-2 Plant Technical Specifi-cation 3.7.10 and ASME Section XI. Testing services were supplied by Qualtec Testing Services Inc..

System pressure testing was conducted by the plant to applicable Plant Technical Specifications and procedures. The Instrumented Inspection Technique was used as applicable. A summary of the specific systems tested is included in this report on Page 6.

11. Conditions Noted
12. Corrective Measures Recommended and Taken CLASS I REACTOR VESSEL A visual examination was conducted on all accessible areas of the vessel interior including upper guide structure, core barrel, and upper head; code categories B-N-l, B-N-2, and B-N-3.

Mechanized ultrasonic examinations were performed on the vessel circumferential welds, longitudinal welds, and inlet nozzles including nozzle inner radius exams. No rejectable indications were noted.

PRESSURIZER Volumetric (UT) examinations were conducted on the upper shell to head weld, the upper shell longitudinal weld, the lower shell to bottom head weld, and the lower shell longitudinal weld. The support skirt to lower head weld was given a surface examination using magnetic particle. No recordable indications were noted.

Volumetric (UT) examinations were also conducted on four of the five nozzle to upper head welds, including inner radius exams.

No recordable indications were noted.

REACTOR COOLANT PUMPS 2B1 reactor coolant pump was disassembled for maintenance and examined. The pump casing welds were radiographed and the casing interior visually (VT-3) inspected. No recordable indications were noted. The pump casing ligament area, studs, and nuts were visually examined. The studs were also volumetrically (UT) examined in place. No recordable indications were noted. A Visual (VT-3,4) examination was performed on the four pump supports. No rejectable indications were noted.

In accordance with NRC Regulatory Guide 1.14,Flywheel Integrity, the flywheel bore and keyways on all four reactor coolant pumps were volumetrically (UT) examined. No recordable indications were noted.

MAIN REACTOR COOLANT PIPING Surface (MT,PT), and volumetric (UT) examinations were conducted on seven circumferential welds, six longitudinal welds, and two branch connection welds. No rejectable indications were noted.

11. Conditions Noted
12. Corrective Measures Recommended and Taken CLASS I (Cont.)

MAIN REACTOR COOLANT PIPING In accordance with NRC Bulletin No. 88-11, a visual (VT-3) examination of the entire pressurizer surge line was conducted.

The area of examination included the piping, pipe supports, whip restraints, and anchor bolts. No gross discernable distress or structural damage was noted.

PRES SURI ZER SPRAY PI PING Surface (PT) and Visual (VT-3,4) examinations were conducted as applicable on selected piping welds and supports. A rigid strut I.D. I SPS-237 was identified as misaligned and having loose parts. Further investigation identified the strut as one which was intentionally moved due to maintenance activities. The strut was reinspected when the maintenance activity was complete and found acceptable. No rejectable indications were noted.

SAFETY INJECTION/CHARGING/LETDOWN PIPING Visual, surface, and volumetric examinations were conducted on selected piping welds, valves, and supports. Visual examination revealed incomplete thread engagement on valve V-2515 (one stud/

nut). Per Plant procedures, the bolting was adjusted to meet minimum thread engagement, re-examined, and found acceptable.

CLASS II STEAM GENERATORS (Secondary side)

Volumetric (UT) examinations were performed on the intermediate shell to cone weld and the feedwater nozzle to shell weld of 2A Steam Generator. Surface (MT,PT) examinations were conducted on the feedwater nozzle to shell weld and selected integral attachments. I.D. geometry was noted on the shell weld (UT).

MAIN STEAM Visual(VT-3), surface (MT), and volumetric (UT) examinations were conducted as applicable on selected piping welds, supports and integral attachments. No rejectable indications were noted.

11. Conditions Noted
12. Corrective Measures Recommended and Taken SAFETY INJECTION/SHUTDOWN COOLING PIPING Visual, volumetric, and surface examinations were conducted on selected piping welds, valves and supports. No rejectable indica-tions were noted.

SNUBBER EXAMINATION AND TESTING Visual examination (VT-3,4) was conducted on 100% of the Unit's snubber population per Plant Technical Specifications. A total of 105 snubbers were functionally tested. This included the initial 10 4 sample, the second sample was required due to failures, and the testing of previous failures. Complete examination and test results are on file at the Plant. A summary of the functional test results is included with this report.

SYSTEM LEAKAGE/PRESSURE TESTING The system leakage tests and visual (VT-2) examinations of class I systems were performed by the Plant prior to plant startup.The system leakage test was conducted during Reactor Coolant (RCS) overpressure. The pressure testing documented on page 6 of this report includes all testing done from 11/25/87 up to 4/28/89.

All the above conditions were dispositioned in accordance with Plant Procedures.

The Examination Summary Tables included with this Report provide the results for the non-destructive examinations performed and a report on percent of examinations complete as of 6/30/89.

An explanation of the Summary Table format is also included.
