. INTRODUCTION -

VERMONT YANKEE PRIMARY CONTAINMENT LEAK RATE TESTING PROGRAM The Primary Containment serves as a leak tight barrier against the f uncontrolled release of radioactivity to the environment.

The leak rate testing program verifies the integrity of the primary reactor 4 containment, related systems and components penetrating the primary containment pressure boundary.

The VY PCLRT program conforms to regulations set forth by 10CFR50 Appendix J, entitled " Primary Reactor Containment Leakage Testing for

  • Water-Cooled Power Reactor".

There are three types of tests which make up'the VY PCLRT program; they are: Type A,-B and C tests. The Type A test is implemented by O.P. 4029 whereas the Type B and C test are implemented by O.P. 4030.

The Type A test measures the primary reactor containment overallintegrated ,

leakage rate. The Type B test measures the localleakage across the primary containment penetrations and seals, which ar'e listed in the VY PCLRT Program.

,The Type C test measures the localleakage across the containment isolation I 0alves, which are listed in the VY PCLRT Program.

L

3 j NOTES s

1. - Type C testing is not required for the 1-inch diameter lines with *

- at least one isolation valve and a cap in series, which is under administrative control or where plug-in test taps form the second barrier, which is also under edministrative control.

' 2.' - Type ~ C testing is not required for lines forming a closed, seismic qualified loop totally within the reactor building, whose 30-days water supply is assured via the torus or reactor vessel and no single active failure can preclude the continuous availablility of a water seal.

3.' Type C testing is not required for valves which remain open with the system operating at pressures greater than Pa throughout the 30-day post-accident period, considering possible single active failure.

4. Type C testing is not required for instrument lines of 1-inch or less .

that meet the provisions of Regulatory Guide 1.11.

5. Type C testing is not required for instrument . lines of 1-inch or less forming a closed system within containment with no interface with containment atmosphere, has no automatic isolation, but remote manual

. Isolation upon failure of a line.

6. Type C testing is not required for standby liquid control system lines equipped with normally closed valves, leak tight against reactor system

. pressure with explosive charges to open the valves under certain conditions.

7. Appendix J permits testing of isolation valves in the direction opposite the direction of accident pressure, where the leakage is equivalent in -

either direction.

Vermont Yankee's Leak Test Program List In order to verify containment isolation, the Type A, B, and C

' Tests are performed in accordance with 10CFR50, Appendix J. The Type B and C tests are used to quantify the ability of the containment penetrations and isolation valves to pe.rform their intended function.

The progrsm list includes all the penetrations which are to be tested as per the requirements of Appendix J. Where the requirements of Appendix J do not apply, the program's comment section provides ,

.(h' t reference notes which contain the applicable explanations.

. Where exemptions to Appendix J are required, the program's comment

~

section will provide the relief ~ request number.

{' . Number: D-1 System: Feedwater Valve: 2-28A, 2-28B Penetration No.: X-9A, X-9B Size: 16" 7 Function: Check Valve for Reverse Flow Isolation Test Requirement: Appendix J, Type C Basis for Relief: Type C testing of the inboard feedwater check valves is g

not required based on the following:

1. The closing of the outboard check valves is very reliable.

~

The outboard valves will fail to close only if they are -

physically blocked by some foreign material or as a result of serious mechanical binding.

2. Even if the outboard valve fails to close, the inboard valve will remain water covered until all remaining feedwater has leaked through, providing a period of time to shut the motor-operated valves before there is any

{ escape of containment atmosphere.

3. Even if the outboard valve fails to close, and the motor-operated valves are left open, system operating pressure greater than Pa can be maintained which will prevent leakage through the inboard valve out into the system. -
4. VYNPC found that significant effort was required in re-q placing the outboard feedwater check valves. Both VYNPC

~

and NRC agree that anticipated radiation exposures associated with replacing the inboard check valves far k exceed the benefits of replacing these valves (ie ALARA) bas'ed on the outboard feedwater check valve experience.

' Function: Main Steam Line Isolation Testing Requirements: Appendix J, Type C ,

Basis for Relief: The design of the main steam isolation valves is such that testing between the inboard and outboard -

valves at 44 psi would lift the disc of the in-board valve.

Alternate Testing: Valves will be leak tested at 24 psi with an acceptance criteria of 11.5 scfh.

coolant pressure, which is ciders of magnitude higher than post-accident containment pressure. Any system leakage would be identified during plant operation and, subsequentJy repaired so that it can be relied upon to contain post-accident pressure should the need arise.
