Deficiencies for the Master Nuclear Certified Listing (MNCL) and items on the list are reported according to which document?

The correct answer is indeed associated with the reporting of deficiencies for the Master Nuclear Certified Listing (MNCL) and related items. DAFMAN 91-221 provides the necessary guidance for documenting and reporting deficiencies within the nuclear enterprise. This document outlines the procedures and standards for ensuring accountability and oversight in the management of nuclear-related operations.

Understanding the context of DAFMAN 91-221 is crucial, as it addresses safety and compliance measures pertinent to nuclear certification processes, ultimately ensuring that all items listed under the MNCL meet required standards. This aligns with the overarching goals of maintaining a safe and effective nuclear deterrence strategy.

In contrast, other options such as AFI 90-802, AFDP 13-5, and AFI 21-101 cover different areas: AFI 90-802 focuses on the overall safety program; AFDP 13-5 relates to nuclear operations but does not specifically address deficiencies in the same manner; and AFI 21-101 centers around aircraft maintenance management rather than nuclear certification. Each of these documents directs attention to significant topics within their respective realms, but none serve the specific purpose of deficiency reporting for the MNCL like DAFMAN 91-221 does.
