SCOPE 2RE04 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 2.
This report covers selected ASME Code Class 1 and 2 systems and 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 respectively. 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 selection process will continue until all ASME Code Class 2 systems / components are examined in accordance with Table IWC-2500-1, Examination Category C-H for ASME Code Class 2 systems / components. This examination category establishes the frequency at each inspection period. These pressure tests are performed in the second period of examination. The remaining second period examinations are anticipated to be completed by the end of the second inspection period time frame.
The System Leakage Test (IWA-5200(a)] conducted on i
Class 1 systems / components in accordance with Examination Category B-P, also satisfied the system pressure test required by IWA-5214(e) subsequent to the disassembly and reassembly of mechanical joints in ASME Code Class 1 components.

ABSTRACT OF EXAMINATIONS A System Leakage Test as prescribed by IWA 5211 (a) for all ASME Code Class 1 Pressure Retalning Components was conducted in accordance with Table IWB-2500-1, Examination Category B-P, item Nos. B15.10, B15.20, B15.30, B15.40, B15.50 B15.60 and 815.70.
The Pressure Test and VT 2 visual examinations were conducted in accordance with Piant Surveillance Pressure Test Procedure, OPSP15-RC-0001, Reactor Coolant System Leakage Pressure Test (Rev. 2) at the condusion of the fourth refueling outage. ASME Code Class 1 piping and valves are specifically identified in the above referenced procedure, in addition, the above System Leakage Test also satisfied the requirement for a System Pressure Test subsequent to the disassembly and reassembly of mechanical joints in ASME Code Class 1 components as prescribed by IWA-5214 (e).
Also, System Pressure Terts subsequent to 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 ZE-0027, ASME Section XI Post-Maintenance Pressure Test (Rev. 9) for individual work items performed outside the scope of the fourth refueling outage.
12.
ABSTRACT OF CORRECTIVE MEASURES RECOMMENDED AND TAKEN The Visual Examinations (VT-2) performed during these Pressure Tests found 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.

ABSTRACT OF EXAMINATIONS System inservice Tests as prescribed by IWA 5211 (c) were conducted on selected ASME Code Class j
2 Pressure Retaining Components in accordance with Table IWC-2500-1, Examination Category C-H, J
ltem Nos. C7.30 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-CM-0001 - RCB H, Monitoring Functional Pressure Test, (Rev. 5)
OPSP15 FW-0001 - Feedwater System inservice Pressure Test (Rev. 0)
OPSP15-RC-0001 - Reactor Coolant System Leakage Pressure Test, (Rev.1)
ASME Code Class 2 piping and valves are specifically identified in the above referenced procedures.
These test procedures were conducted during the time period of May 31,1994 to November 15,1995.
12.
ABSTRACT OF CORRECTIVE MEASURES RECOMMENDED AND TAKEN The Visual Examinations (VT 2) performed during these Pressure Tests found only minor leakage at mechanical joints such as valve stems and flanged connections.
