SUPPLEMENTARY INFORMATION:
I. Background: National Security Presidential Memorandum No. 20 (NSPM-20) directed the
NASA Administrator to establish the INSRB to replace the ad hoc Interagency Nuclear Safety
Review Panels used for prior missions. The INSRB was first empaneled in 2020, and per NSPM20 consists of “representatives from the Departments of State, Defense, Energy, and
Transportation, the Environmental Protection Agency, NASA, and, as appropriate, the Nuclear
Regulatory Commission.” Following its formation, the INSRB issued a Charter, as well as a
guidance document known as the INSRB Playbook. While the INSRB’s scope is defined by
NSPM-20, and while its conduct of operations is described in the INSRB Charter and the INSRB

Playbook, the INSRB has continued to receive questions from the community-at-large that
suggest misunderstandings. The INSRB is hosting this virtual open house as a diverse means of
communicating to interested parties about what the INSRB is and is not charged to do, and how
it conducts its business.
II. Resources: The INSRB Charter and INSRB Playbook are publicly available at the following
link: https://sma.nasa.gov/sma-disciplines/nuclear-flight-safety. This same webpage contains an
INSRB brochure and an INSRB presentation that will form the basis for the remarks made
during the virtual open house.
Dated: June 21, 2024.

NASA Nuclear Flight Safety Officer.
