3.3 TESTING APPROACH
WHC-SD-W100-TI-003 Rev. 0
The WFQ test work is directed toward three goals. First, suitable
formulations that can produce waste forms meeting all performance
specifications and regulatory requirements must be developed. Second, the
in-drum mixing process must be developed to determine the effect the mixing
process has on waste form performance and to evaluate the ability of the
mixing process to achieve the required process objectives. Third, hot testing

for verification of results obtained with waste surrogates. Figure 3-1
depicts the strategy for the WFQ program.
The objectives of the WFQ programare to_c9nfi-m irhe technical basis for
the process design by demonstrating successful MLLW immobilization
r`ormulations and mixing processes. A further objective is to gather the data
needed for support of detailed facility design and regulatory permitting

The test results reported in this status report have been focused on
formulation development efforts. Screening tests and performance testing have
=`= been performed on surrogate waste forms representing 80% of the design basis
feed volume. Future testing, described in detail in Section 5.3 of this
0°'1 report, will be directed toward mixing process demonstration and optimization
of the formulations and immobilization processes.

A brief description of the major objectives of the WFQ program and the
interfaces between WFQ and other key project activities is presented in the
following text. Figure 3-2 presents a logic diagram outlining the test
-program and the flow-3f iPf"rmation between the various project activities
relating to the WFQ program.
3.3.1 Confirm Process Design
Confirmation of the immobilization systems process design is the primary
objective of the WFQ program. The process design basis will be confirmed when
a successful immobilization formulation has been developed for each feedstream
and when the in-drum mixing process has been demonstrated.
Development of a successful formulation is achieved when a surrogate that
is chemically similar to the waste stream in question is successfully
immobilized. Successful immobilization is defined as production of final
waste form specimens that meet or exceed the WRAP 2A waste form performance
specifications, as measured through laboratory tests of waste form
performance.
The in-drum mixing process will be demonstrated when surrogates that are
physically similar to the WRAP feedstreams have been successfully mixed with
^amoaillzAti-on ana'trices using the in-drum mixing equipment. Successful mixing
- is defined as production of a mixture that meets or exceeds the mixing process
objectives, as measured through tests on full size pilot plant mixing
equipment.
