ISO 13463 pdf download.Nuclear-grade plutonium dioxide powder for fabrication of light water reactor MOX fuel — Guidelines to help in the definition of a product specification
1 Scope
This International Standard applies to nuclear-grade plutonium dioxide powder (PuO 2 ), for fabrication of light water reactor MOX fuel. It defines minimal requirements for the product, quality assurance and quality control. It can be modified or amended once the powder supplier and the MOX fuel fabricator agree. This International Standard sets, in that respect, guidelines for the definition of a product specification.

3 General requirements
3.1 Quality assurance The supplier shall establish a quality assurance system in accordance with ISO 9002, or equivalent. In that respect, the following principles shall be respected. — Plutonium dioxide shall be produced with a qualified process, that is to say, in accordance with ISO 9002. Qualification shall encompass the powder fabrication process itself (homogenization, conditioning, etc.) but also the powder sampling process and characterization methods. — A product quality plan shall be established, it shall contain at least the following information: — a fabrication description including the list and values of the important parameters regarding the quality of the finished product; — a description for on-line inspection methods and for analytical determination (equipment, measurement principle and related statistical characteristics).3.2 Sampling 3.2.1 PuO 2 powder lot A lot is defined as a quantity of material that is uniform in isotopic, chemical and physical characteristics and free from foreign material. 3.2.2 Sample size Each powder lot shall be represented by a test sample. Traceability between the PuO 2 powder lot and the sample shall be maintained. The recommended sample size shall be 1 0 g. 3.3 Packaging Each PuO 2 powder lot shall be packaged in containers ensuring material confinement. Each container shall have a unique reference number. Traceability between the different containers of each lot and the sample on which analytical determination are performed shall be maintained. 3.4 Documentation For each lot, the following documents shall be provided: — a conditioning certificate identifying the different containers of the lot; — a record of all data from tests and analytical determination; — a declaration of conformity of the PuO 2 powder lot.
