- Introduction This report is issued as a followup.to the " Reactor Containment Buidling i Integrated Leak Rate Test Supplement 1" sent to Harold Denton on 2/27/81.-

Its purpose is to document leak rate testing that has been performed since the previous report was written.

Testing of New Piping Penetration A new piping penetration has been added to containment since the last ILRT.

Penetration M383 (Water Addition to the Ice Condenser) was tested using

- PT/1/A/4200/01C, Isolation Valve Leak Rate Test, on 7/8/82. The measured

-5 leakage of the penetration was 5 SCCM or 5.5 x 10 La. This penetration will not be tested on a periodic basis since it is not a source of bypass leakage.

Testing of New Instrument Penetrations Several new instrument penetrations have been added to containment since the ILRT. Those not previously reported were tested using PT/1/A/4200/21, Instrument Penetration Structural Integrity and Leak Rate Test. This test verified the structural integrity of the weld at the inside of the contain-ment vessel by pressurizing the weld to structural integrity test pressure, holding for 10 minutes, reducing pressure to 14.8 psig, and verifying no

, measurable leakage. The instrument line numbers that were added and tested in this manner art:

1NILT6630 - tested 3/24/81 INILT6640 - tested 3/24/81 l 1NILT6650 - tested 3/24/81 INILT6660 - tested 3/24/81 1NILT6670 - tested 3/25/81 INILT6680 - tested 3/24/81 1RVFE5030 - tested 3/7/82 1RVFE5040 - tested 3/7/82 1RVFE5050 - tested 3/8/82 1RVFE5060 - tested 3/7/82 f
