The mission of the Nuclear Explosive Safety Program is to train, qualify, and maintain qualification of those who serve as members of a Nuclear Explosive Safety Study Group (NESSG) tasked with the responsibility for the safety of the nuclear stockpile in the national interest, and those technical employees and managers whose position requires them to provide management direction or oversight that could impact the safe operation of a defense nuclear facility. There is no charge for any of our classes.


NESSG members shall be independent, knowledgeable personnel having basic knowledge that includes experience with or a working-level knowledge of nuclear explosive development, testing, production, and/or transportation. In addition, a NESSG member shall have relevant ES&H training on personnel hazards and exposure to radioactive and chemical materials.

NESSG members must be trained to a familiarity level, working-level, or an expert level of knowledge as defined by each course in the curriculum; or they are required to demonstrate the ability to perform a task or activity. These levels are defined as follows:

  • Familiarity-Level Knowledge
    Basic knowledge of or exposure to the subject or process adequate to discuss the subject or process with individuals of greater knowledge.
  • Working-Level Knowledge
    The knowledge and ability to monitor and assess nuclear explosive operations, facilities, and activities, to apply Nuclear Explosive Safety Standards, and to reference appropriate materials and/or expert advice as required to ensure nuclear explosive safety.
  • Expert-Level Knowledge
    A comprehensive, intensive knowledge of the subject or process sufficient to provide advice in the absence of procedural guidance.
