Speaker: Jim Glover

​For 19 years, Mr. Glover worked for Exelon as the ILRT and LLRT Appendix J Program Director. During that time, he performed over 100 ILRTs on both BWRs and PWRs. Since then he has performed an additional 40 ILRTs as a private consultant.

Mr. Glover is currently the Chairman of the ANS 56.8 Standards Committee on containment leakage rate testing. He was a member of the NEI AHAC that wrote the original Appendix J guideline document NEI-9401.

He also developed and sold the ILRT and LLRT instrumentation systems which are currently and has been used at most US nuclear plants since 1994.
