In July 2020, DOE and the NTC launched its new learning management system for contractors – Learning Nucleus (LN). This new system greatly enhances the NTC’s ability to provide training and support services to its customers throughout DOE. The easy-to-use interface allows students to access course information, request enrollment into instructor-led sessions, launch eLearning courses, and print transcripts and completion certificates.

Please note that students can no longer access NTC courses through the former system, the Learning Management System (LMS). All NTC courses, student records, and learning histories can be transferred from LMS to LN.


Students can access eLearning course content using the course catalog in Learning Nucleus, located at

How to access Learning Nucleus (LN)

All LMS training history was migrated into the LN. Contractors can gain access to the LN by following the Contractor Initial Access instructions link on this page. These instructions also include the steps to connect previous training to your new LN account.​
