This 24-hour test was conducted on September 22 and 23, 1991, and it demonstrated that the containment leakage under prescribed post-accident conditions was well within the allowable leakage value specified in the STPEGS Technical Specifications. In addition Unit 2 was tested at a higher test pressure (42.5 psig vs 37.5 psig) than previously conducted ILRT's to account for the new calculated containment net free volume. The ILRT was followed by I a successful test to verify instrumentation performance in accordance with 10CFR50 Appendix J. This report is provided for your information and use in accordance with 10CFR50, Appendix J, V.B.
