SCOPE 1RE05 SYSTEM PRESSURE TESTS The examinations summarized in this report were performed in accordance with the 1983 Edition through Summer 1983 Addenda of the ASME Code,Section XI which is applicable to the South Texas Project Electric Generating Station, Unit 1. This report covers 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 second period examinations are anticipated to be completed by the end (9-25-96) of the second inspection period.

l 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 joints in ASME Code Class 1 Systems / Components.

ABSTRACT OF EXAMINATIONS A System Leakage Test as prescribed by IWA 5211 (a) for all ASME Code Class 1 Pressure Retaining Components was conducted in accordance with Table IWB-l 2500-1, Examination Category B-P, item Nos. B15.10, B15.20, B15.30, B15.40, l

B15.50, B15.60 and B15.70.

The Pressure Test and VT-2 visual examinations were conducted in accordance with Plant Surveillance Pressure Test Procedure, OPSP15-RC-0001, Reactor Coolant System Leakage Pressure Test (Rev. 2) at the conclusion of the fifth refueling outage. ASME Code Class 1 piping and valves are specifically identified l

t in the above referenced procedure.

Also, System Pressure Tests subsequent to all of the disassembly and reassembly

['

of mechanical joints in ASME Code Class 1 components as prescribed by IWA-5214 (e) were conducted in accordance with OPGP03-XE-0027, ASME Section XI Repair, Replacement and Post-Maintenance Pressure Testing (Rev. 8) for individual work items performed during the fifth refueling outage as a result of the performance of the System Leakage Pressure Test described above.

l i

l 12.

ABSTRACT OF CORRECTIVE MEASURES RECOMMENDED AND TAKEN The Visual Examinations (VT-2) performed during the Pressure Test found minor i

leakage at mechanical joints such as valve stems and flanged connections. These leaks were evaluated and determined acceptable for continued system operation.

Appropriate corrective action was initiated to correct these leaks.

ABSTRACT OF EXAMINATIONS System Functional and Inservice Pressure Tests as prescribed by IWA-5211 (b) and (c), respectively, were conducted on selected ASME 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 second period of examination in accordance with the following Plant Surveillance Pressure Test Procedures:

OPSP15-CC-0001 -

Component Cooling Water System Inservice Pressure Test, (Rev.1)

OPSP15-CM-0001 -

RCB H Monitioring Functional Pressure Test, (Rev. 5) 2 1 PSP 15-CV-0001 -

Chemical and Volume Control System inservice Pressure Test, (Rev. 2) Inside Containment Portion Only 1 PSP 15-MS-0001 -

Main Steam System inservice Pressure Test (Rev. 5)

OPSP15-RC-0001 -

Reactor Coolant System Leakage Pressure Test (Rev. 2)

OPSP15-RH-0001 -

Residual Heat Removal System Inservice Pressure Test (Rev.1)

ASME Code Class 2 piping and valves are specifically identified in the above referenced procedures. These test procedure were conducted during the time period of January 1,1993 to April 25,1995.

ABSTRACT OF CORRECTIVE MEASURES RECOMMENDED AND TAKEN w

The Visual Examinations (VT-2) performed during these Pressure Tests found only minor leakage at mechanical joints such as valve stems and flanged connections.

These leaks were evaluated and determined acceptable for continued system operation. Appropriate corrective action was initiated to correct these leaks.
