ABSTRACT
In order to consider the conversion of the High Flux
Isotope Reactor (HFIR) from highly enriched uranium (HEU)
to low enriched uranium (LEU), a review of the design
bases and key operating criteria is being performed in
order to develop the scope of the engineering analyses
for a fuel conversion study. The aspects of the review
are discussed and include: current fuel operating
parameters, enrichment-related Safety Analysis Report
sections and Technical Safety Requirements, and the
record of past fuel performance and current fabrication
criteria that would be expected to be matched or applied
or would impact the manufacture of LEU fuel. Finally,
out-of-reactor issues related to a potential LEU fuel
cycle will be discussed. Criteria to bound the
engineering analyses are being developed and are
presented. A set of reactor performance measures is
being developed to quantify the impact on performance
for an LEU core design, and this set is presented. The
HFIR design, criteria, and performance metrics will form
the bases for design analyses of the HFIR core
conversion planned to be performed in 2006.
