Each licensee of a facility, certificate holder, or possessor of nuclear material outside facilities with nuclear materials subject to IAEA safeguards shall submit a material status report for each physical inventory taken in accordance with the material accounting and control procedures required by § 75.21. The material status report must include a DOE/NRC Form 742 and a DOE/NRC Form 742C, which lists all batches separately and specifies material identification and batch data for each batch. The reports described in this section must be prepared and submitted in accordance with instructions in NUREG/BR-0006, NUREG/BR-0007, and NMMSS Report D-24.

Unless otherwise specified in the license conditions, material status reports shall be submitted to the NRC as soon as possible, but in any event no later than 30 days after the start of the physical inventory.

Possessors of nuclear material outside facilities must submit a material status report to the NRC every 12 calendar months, for a reporting period that commences on May 1st and concludes on April 30th of the next calendar year. The annual inventory report must be dated April 30th.
