Welcome to the Containment ILRT Test Team web site. This site offers information valuable to nuclear power plant system engineers preparing to undertake the Primary Containment Integrated Leakage Rate Test (ILRT or PC ILRT), or dealing with Appendix J, Option B program related issues. ILRT The ILRT is a critical path evolution required at all US design nuclear power plants. All US Plants have adopted 10CFR50 Appendix J Option B and need only perform this test at ten to fifteen year intervals. The costly nature of the test (it still costs between $1.5-2.5 million dollars to perform due largely to replacement power costs), combined with its complexities and the fact that it is performed very infrequently, has led most utilities in the U.S. to seek expert consulting assistance in supporting the tests. Driven by the trend to shorter outages with complex work schedules, industry trends have turned from plant owned and maintained test equipment and software to rental of complete test packages. This site is an introduction to the test team that is the first choice in ILRT support for a majority of plants across the US and a growing number abroad. Welcome, look around, and by all means feel free to
