Accurate and precise measurement of Pu and U is critically important for safeguards and is the premise of safeguards inspection by IAEA at Nuclear Fuel handling facilities. Quality control section of Plutonium Fuel Development Center (PFDC-lab) has been analyzing the Pu and U isotopic compositions by MS as well as its content by IDMS of the MOX fuel pellet and its source materials for the accountancy purposes. To maintain and improve analysis quality and analysis reliability, PFDC-lab decided to have accreditation of ISO/IEC 17025 (International standard for the General requirements for the competence of testing and calibration laboratories). PFDC-lab established analysis quality management system, acquired the knowledge and information of uncertainty evaluation under cooperative study with US DOE's NBL, ensured our analysis traceability and validates our methods to meet technical requirements. In conclusion, we have accredited for ISO/IEC 17025 in March 1st, 2010.
