SCOPE 1

5 1RE06 SYSTEM PRESSURE TESTS 1

! The examinations summarized in this report were performed in j accordance with the 1983. Edition through Summer 1983 Addenda of j the ASME Code,.Section XI which is applicable to the South Texas

Project Electric Generating ~ Station, Unit 1. This report covers I

selected ASME Code Class 1 and 2 Systems / Components. Examinations and tests required by the Code are scheduled in accordance with

" Inspection Program B" as defined in IWB-2412 and'IWC-2412 for ASME Code Class 1 and 2 Systems / Components. All ASME Code Class 1 components were examined as prescribed by Table IWB-2500-1, Examination Category B-P which established the examination frequency at each refueling outage. The ASME Code Class 2 Systems / Components were selected'on a' prorated basis. This prorated selection process will continue until all ASME Code Class 2-Systems / Components are examined in accordance with Table-2500-1, Examination Category C-H. This examination category for ASME Code Class 2-Systems / Components established the examination frequency at each. inspection period. The remaining third period examinations are anticipated to be completed by the end (9-24-99) of the third inspection period.

The System Leakage Test [IWA-5211(a)] conducted on Class 1 Systems / Components in accordance with Examination Category B-P also satisfied the pressure tests required by IWA-5214(e) subsequent to the disassembly and reassembly of mechanical jointe in ASME Code Class 1 Systems / Components. j l

10. ABSTRACT OF EXAMINATIONS i

A System Leakage Test as prescribed in IWA-5211(a) for all ASME Code Class 1 Pressure Retaining Conponents was conducted in accordance with Table IWB-2500-1, Examination Category B-P, Item Nos. B15.10, B15.20, B 15.30, l B 15.40, B 15.50, B 15.60, and B 15.70.

The Pressure Test and VT-2 visual examinations were conducted in accordance with Plant Surveillance Pressure Test Procedure, OPSP15.RC-000), Reactor Coolant System Leakage Pressure Test (Rev. 3) at the conclusion of the sixth l

refueling outage. ASME Code Class 1 piping and valves are specifically identified in the above reference procedure. j Also. System Pressure Tests subsequent to all of the disassembly and reassembly of mechanicaljoints in ASME Code Class I components as prescribed by IWA-5214(e) were conducted in accordance with OPGP03-ZE-0027, ASME Section XI Repair, Replacement and Post-Maintenance Pressure Testing (Rev. 9) for individual work items performed during the sixth refueling outage as a result of the performance of the System Leakage Pressure Test described above.

12. ABSTRACT OF CORRECTIVE MEASURES RECOMMENDED AND TAKEN The Visual Examinations (VT-2) performed during the Pressure Test found minor leakage at mechanical joints such as valve stems and flanged connections. These leaks were evaluated and determined acceptable for continued operation.

Appropriate corrective action was initiated to correct these leaks.

10. ABSTRACT OF EXAbilNATIONS System Functional and inservice Pressure Tests as prescribed by IWA-5211(b) and (c), respectively, were conducted on selected A SME Code Class 2 pressure retaining components in accordance with Table IWC-2500-1, Examination Category C-H, Item Nos. C7.10, C7.30, C7.50, and C7.70.

The Pressure Tests and VT-2 visual examinations were conducted during the third period of examination in accordance with the following Plant Surveillance Pressure Test Procedures:

OPSP15-CS-0001 Containment Spray System Functional Pressure Test (Rev. 2)

OPSP15-FW-0001 Feedwater System Inservice Pressure Test (Rev.1)

OPSP15-RC-0001 Reactor Coolant System Leakage Pressure Test (Rev. 3)
