QUALITY ASSURANCE PLAN FOR MIXED OXIDE FUEL FOR Lb2'BR
R. K. Zeigler
Los Alamos Scientific Laboratory
of the University of California
Los Alamos, New Mexico
An evaluation of the adequacy of the methods of analysis is
presented for chemical specifications of LMFBR/FFTF mixed uranium-
plutonium oxide fuel. This evaluation is based on statistical
analyses of the results obtained by seven laboratories on a dis-
tributed batch of FFTF fuel pellets and distributed special blends
of certain impurities and a high purity uranium-plutonium oxide
matrix. Based urn the results of this evaluation a quality
assurance program will be discussed which will ensure the con-
tinuing existence of quality data for the chemical characterization
of LMFBR/FFTF mixed oxide fuels.
Early in 1968 a joint project was undertaken by the Los Alamos Scientific Labora-
tory (LASL) and the Pacific Northwest Laboratories (PNL) for the Fuels and Materials
Branch, Division of Reactor Development and Technology, USAFC. This project had, and
still has, as its major objective the production of quality data for the character-
ization of LMF'BR/FFTF fuel. The desired analyses to be made on this fuel are as fol-

In order to implement this project, LASL assumed the responsibility of planning the
analytical program, evaluating the data and furnishing guidance to fuel producers. A
close working relationship was established between LASL and PNL in order to get this
project underway. Early in the program certain goals and objectives were formulated as
being necessary for this program.
A major factor in the production of high-quality, well-characterized LMFBR/FFTF
fuel is technical competence of a high degree for doing the required chemical analyses
and other measurements as required by LM'BR/FFTF fuel specifications. To ensure this
caliber of competence, the analytical and quality assurance program will have the fol-
1. To evaluate the capabilities of potential fuel producers for making the analyt-
ical measurements on LMFBR/FFTF fuel which are necessary to ensure the uniformly high
quality fuel required by the LhFBR/FETF Program.
2. To provide technical guidance, as may be required, to ensure that these capa-
bilities are established at the level required by LM'BR/FFTF fuel specifications.
3. To establish and conduct a quality assurance program that will ensure contin-
