to the public or entering the comment into ADAMS.

II. Discussion

    The NRC has identified a potential generic issue associated with 
electrical equipment containing component made of aluminum. If the 
identified equipment were to experience a HEAF the presence of aluminum 
may cause greater damage to structures, systems, and components than 
previous analyses indicated. This generic issue has met all seven 
screening criteria of the generic issues program and is currently in 
the assessment phase (ADAMS Accession No. ML16349A027). To better 
understand the impact of aluminum, the NRC is sponsoring large- and 
small-scale testing. The large-scale testing will be undertaken as part 
of an international effort and the draft test plan for that program is 
publicly available (ADAMS Accession No. ML17201Q551).
    The purpose of this draft test program is characterize aluminum 
particle size distribution, rates of production and morphology 
(agglomeration) of HEAFs involving aluminum conductors. The 
measurements from these experiments will be used to support development 
of a HEAF/Aluminum combustion energy balance model to better 
characterize the aluminum HEAF hazard. This modeling effort will 
support advancements to quantify hazards HEAF pose to nuclear power 
plant risk. The small-scale testing is expected to be performed prior 
to any full-scale testing. The results from the small-scale work is 
expected to help inform to the large-scale test results and to support 
evaluation of the numerical method predictive capability. Model 
development is outside the scope of this test plan and is expected to 
be completed by a third party. This draft test plan has been developed 
by Sandia National Laboratories.
    The NRC is seeking public comment in order to receive feedback from 
the widest range of interested parties and to ensure that all 
information relevant to

is issued for comment only and is not intended for interim use. The NRC 
will review public comments received on the documents, incorporate 
suggested changes as necessary, and make the final test plan available.
