1.0 PURPOSE, SCOPE, AND DISCUSSION 1.1 Purpose The Fourth Ten-Year Interval Inservice Inspection Pressure Testing Program (Program) implements the requirements of Title 10 Code of Federal Regulations, Part 50, Section 50.55a, Codes and Standards (IOCFR50.55a) dated September 26, 2002, pertaining to pressure testing and VT-2 visual examination of systems or portion of systems for the three periods of the Interval.
1.2 Scope The scope of this procedure is to identify the systems, based on the ASME group classification criteria, for pressure testing, to provide a scheduling guideline for the performance of periodic pressure testing, and to direct the required pressure testing in support of the AP 0070, ASME Section XI Repair and Replacement Procedure.
1.3 Discussion The Code of Record (Code) for the Program is the American Society for Mechanical Engineers Boiler and Pressure Vessel Code,Section XI, "Rules for Inservice Inspection of Nuclear Power Plant Components" (ASME Section XI - 1998 Edition through the 2000 Addenda).
The Program incorporates the alternative requirements for pressure testing and VT-2 visual examination as outlined in Regulatory Guide 1.147, as needed. Presently, the following Code Cases are being implemented:
None The Program additionally incorporates the alternative requirements for pressure testing, VT-2 visual examination, or corrective measures as outlined in relief requests. Presently, the following relief requests are being implemented:
PT-1: For use of a system leakage test in lieu of the Class 3 "Interval" hydrostatic test The Program was developed by updating the Third Ten-Year Interval Inservice Inspection Pressure Testing Program to the requirements of 10CFR50.55a and the Code. The Program scope was adjusted as required. A continuity of periodicity and frequency was maintained.
The Program determined system ASME Classifications are based on Regulatory Guide 1.26 and ANS-22, Draft 4, Rev I guidelines that are applicable to water-, steam-, and radioactive-waste-containing components important to the safety of water-cooled nuclear power plants. Systems such as instrument and service air, diesel engine and its auxiliary support systems, etc., that are not within the guideline's scope are not required to be classified and included in the Program.
System or portions of systems included in the Program conform to Quality Group A, B, or C criteria and corresponding ASME construction codes. The Program's ASME Class pressure boundaries, using the above guidelines and additional guidelines provided by IOCFR50.2, may PP 7034 Rev I Page 3 of II
not correspond to the system Safety Classifications (i.e., SCx) per AP 6006 (e.g., nonisolatable SC 2 portions of the Reactor Coolant Pressure Boundary are classified as ASME Class I by the Program for pressure testing and VT-2 visual examination purposes, etc.).
The Pressure Test Table (Table I) contains the Program determined system AMSE Class, Status (Operating or Non-operating during normal operating conditions), and Category. It also includes systems or portions of systems that are considered optionally upgraded as annotated in the Comments/Remarks. Optionally upgraded systems are provided with a Class and Status.
The Program schedules and frequencies are based on IWA-2432 of the Code, "Inspection Program B," consisting of four ten-year intervals with three periods per interval. The relative interval and period starting and ending dates are outlined in the following matrix:
Period I I Period 2 l Period 3 Interval 1 On-line Dec. 1, 1972 l to April 30. 1983 2 May 1, 1983 Scpt.

[RIRO 24 & 25] [RFO 26, 27, & 28] [RFO 29 & 30]
The First Interval was five years long, due to the delay inthe development and implementation of ASME Section Xl 2 The end date of the First Interval was extended by five months, in accordance with IWA-2430(c), to permit inspections concurrent with a plant refueling outage. Consequently, all subsequent intervals were adjusted forward five months In the Second Interval, the end date of Period I was extended by four months to reflect the 1985-86 pipe replacement/refucling outage (9months duration) in accordance with IWA-2430(c). Consequently, all subsequent intervals were adjusted forward four months Vermont Yankee's onerating license exnires March 21.2012 Table 1 contains the Fourth Interval (i.e., I", 2 nd, & 3 rd Periods) forecasts of the expected refueling cycle frequencies for the Pressure Tests. The AP 4000, Surveillance Program database provides the scheduling for pressure testing and VT-2 visual examination.
Pressure testing and the VT-2 visual examination to support AP 0070, "ASME Section XI Repair and Replacement Procedure" is an unscheduled activity, being conducted on an as needed basis.
The information contained in Table I is also used to determine the requisite applicability for pressure testing, as modified by IWA-4540(b) of the Code. Requisite Hold(ing) time, prior to examination, is also determined from the Table I and conditions specified by the Program.
2.0 DEFINITIONS 2.1 Asset - A component as described in EMPAC 2.2 Automatic closure - An action of a valve to close in response to a protection or system isolation signal (e.g., MOV, AOV, etc) or to a system condition (i.e., check valve) when the safety function is required.
PP 7034 Rev 1 Page 4 of I I
2.3 Component - An item in a nuclear power plant such as a vessel, pump, valve, piping system, or component support.

APPENDIX A 10 CFR 50.55a Request Number: PT-1 Proposed Alternative In Accordance with 10 CFR 50.55a(a)(3)(i)
- 1. ASME Code Component(s) Affected All ASME Code Components within the scope of 10 CFR 50.55a(g) in the following Systems:
Service Water Fuel Pool Cooling Alternate Cooling Subsystem of Reactor Building Closed Loop Cooling Water
2. Applicable Code Edition and Addenda
ASME Section XI - 1998 Edition through the 2000 Addenda
3. Applicable Code Requirement
Table IWD-2500-1, Category D-B, Item D2.20
- 4. Reason For Request ENVY has concluded that Code Case N-498-1 is not applicable to the 1998 Edition through the 2000 Addenda and therefore requests an alternative to the code requirements on the basis that the proposed alternative would provide an acceptable level of quality and safety.
- 5. Proposed Alternative and Basis for Use ProposedAlternative:
(1) A system leakage test, in accordance with IWA-521 1(a), shall be conducted at or near the end of each inspection interval or during the same inspection period of each inspection interval at the system nominal operating pressure.
(2) The boundary subject to test pressurization during the test shall extend to all Class 3 components included in those portions of systems required to operate or support the safety system function up to and including the first normally closed valve, including a safety or relief valve, or valve capable of automatic closure when the safety function is required.
(3) Prior to the VT-2 visual examination a holding time of:
For Systems In Service During Normal Operating Conditions - at least 10 minutes is required for noninsulated components or at least 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> is required for insulated components after attaining system pressure, unless the system has been in service for the minimum required holding time; or For Systems Not In Use During Normal Operating Conditions - at least 10 minutes is required after attaining system pressure.
(4) The system shall be maintained at the nominal operating pressure during performance of the VT-2 visual examination of all components identified in (2) above.
(5) Test instrumentation requirements of IWA-5260 are not applicable.

APPENDIX A (Continued)
Basis:
ASME Section XI 1998 Edition through the 2000 Addenda requires only a System Leakage Test to fulfill all inspection period and interval pressure test conditions prior to a VT-2 visual examination for Class I and 2 pressure retaining components.
For the Class 3 systems in service during normal operating conditions, Auxiliary Operators certified as VT-2 visual examiners, perform tours three times a day in accessible areas during normal plant operations. For all systems, control room operators can observe system pressure anomalies or an increase in sump pump operation. It is for more likely that a pressurized component will leak under extended operation, than during a static test at a higher pressure that is only observed for a brief time.
The normally, Class 3 systems not in use during normal operating conditions, are operated to demonstrate safety system functionality or to satisfy technical specification surveillance requirements quarterly and are therefore, similarly monitored operationally 4 times per year or 40 times per inspection interval. Additionally, the proposed alternative holding time is the same as per 10CFR50.55a(b)(2)(xx) for the system leakage test requirements performed once each inspection period for Class 2 and 3 systems not in use during normal operations. The minimum 10-minute holding time prior to the VT-2 visual inspection will provide adequate assurance of the leak-tight integrity of all components.
As evidenced by the acceptability of Section XI ASME Code Case N-498-1, the hydrostatic testing requirement does not provide a compensating increase in the level of quality or safety.
- 6. Duration of Proposed Alternative Fourth Ten-Year Inservice Inspection Interval
- 7. Precedents Requested alternative is similar to that provided in the approved Section XI ASME Code Case N-498-1 found acceptable in Regulatory Guide 1.147 Revision 12 and ENVY's Third Inservice Inspection Interval approved relief request P-3.
