During the performance of this test the closing torque switch setting on this MOV was raised, resulting in an increase in thrust of about 20.4%.

The engineer immediately recognized that this MOV had recently been adjusted on December 19, 2001, and suspected that no LLRT had been performed. Subsequent investigation revealed that the As Found and As Left LLRT required by the 10CFR50 Appendix J, "Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors", program had not been performed.
