ILRT and LLRT Seminars

On-Site as Well as On-Line Classes Available

Integrated Leakage Rate Testing Seminar

August 17, 18 and 19, 2021

On-Line or On-Site Group Classes Available Upon Request 














Local Leakage Rate Testing Seminar

August 10, 11 and 12, 2021

Both On-Line or On-Site Classes Available Upon Request


Testing Reduction Evaluations on Your Plant’s Systems

Testing reductions may often be found in many plant’s LLRT programs. Attendees

will be asked to transmit information to us on likely candidate pathways in their

program prior to the seminar. These will be step by step evaluated as a part of

this seminar.

LLRT Equipment & Hands-On Testing of Type B and C Pathways

This seminar will include hands-on local leakage rate testing using industry

standard equipment. Attendees may even bring their own equipment for

use and demonstration if they like. (Not possible for on-line class).

Instructor: 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 80 ILRTs on both BWRs and PWRs. Since then he has performed an additional 30 ILRTs as a private consultant with Graftel, LLC.

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, manufactured and sold the ILRT and LLRT instrumentation systems which are currently and have been used at most US nuclear plants since 1994.
