As part of the DOE Nuclear Criticality Safety Program, a series of training modules are provided to assist site training organizations in developing a comprehensive criticality safety training program. These modules are intended to be used in conjunction with other resources such as the NCSP Nuclear Criticality Safety and University courses. The material in these NCSET modules is suitable for introductory level training of criticality safety personnel who either do not have a nuclear engineering background or who need a basic level refresher course.

These training materials have been developed for the criticality safety user community. Feedback from the users is important so that new modules can be designed and current modules improved to maximize their benefit to the largest possible audience. Please send your comments, suggestions, etc. to ncsp-mgmt [at] llnl.gov (ncsp-mgmt[at]llnl[dot]gov).
