What are the principles of nuclear material control and accountability?

The correct answer emphasizes the importance of effective systems designed specifically for tracking and managing nuclear materials to prevent theft or misuse. In the context of nuclear material control and accountability, these systems are critical for ensuring that all nuclear materials are accounted for at all times. This includes establishing protocols for monitoring, reporting, and verifying the status of nuclear materials, which helps to prevent potential diversion for malicious purposes or accidents.

The principle of accountability also involves creating comprehensive inventories, conducting regular audits, and implementing security measures to safeguard nuclear materials. By maintaining strict oversight and control, organizations can ensure compliance with national and international regulations aimed at enhancing security and minimizing risks associated with nuclear materials.
