Inspection

NMCC inspectors perform accountancy, physical, and other verifications on the nuclear material present at the installations to verify the correctness and coherence of these declarations with the physical reality.

Sample Analysis

In order to confirm the operator’s measurement precision, accuracy and the reliability of the material balance reports, take a small amount of nuclear material sample, and analyze in the Japan’s safeguards analytical laboratories.

Information Processing

By checking the accuracy, completeness and coherence of operator’s accounting records and measurement of nuclear materials, maintain the quality of operator's accounting system to the international standard level.

Information Analysis

To examine correctness of operator’s measurement system, various information obtained in safeguards inspection, and analysis results of the samples are statistically compared with operator’s accounting reports.
