The results for all the measurements of Phase II are given in reference (1) The
conclusions from the evaluation of the Phase II data are as follows: (1) It provided
an understanding of the capabilities and limitations of the analytical methods used by
the participating laboratories for the chemical characterization of LMFBR-type fuels
as required by the specification. (2) It provided an improved evaluation of the
qualifications and capabilities of potential fuel producers to maintain adequate
specification control by competent chemical analysis. (3) It provided useful esti-
mates of the analytical measurement errors and the between-pellet variabilities that
can be expected for most of the chemical specifications fcr mixed oxide fuels. (4) It
showed that close control will be required of the sampling and analytical methods used
by the fuel producers in order to ensure complete and adequate characterization of the
high quality fuel necessary for the LMFBR program.
Based upon the results of this evaluation, recommendations were made for the
qualification and control of analytical laboratories for mixed oxide fuel analysis.
QUALIFICATION AND CONTROL OF ANALYTICAL CHEMISTRY LABORATORIES
An essential part of a fuel production process is an overall quality assurance
program that is designed to ensure that the fuel meets all specifications. Analytical
laboratories need to establish their technical competence to do the chemical analyses
required for the characterization of fuel. Also a quality control program for the con-
tinual evaluation of analytical data obtained during periods of fuel production needed
to be established. In order to ensure that quality data would be obtained, certain
minimum standards were recommended for the analytical laboratories involved in fuel
production:
(1) Laboratory Qualification Program. The qualification of an analytical laboratory
shall be based on its demonstrated competence to do the specifications analyses of the
uranium dioxide powder or uranylnitrate, uranium dioxide pellets, plutonium dioxide or
plutonium nitrate, and mixed oxide powder and pellets. This competence shall consist
of:
(a) The satisfactory use of approved methods which have accuracies and precisions
adequate for the specification requirements. Methods which have been demonstrated to
have adequate precisions and accuracies may be obtained from the purchaser. If other1 -
