Production test IP-696 evaluation of arch-rail supports

摘要

Large scale self-support fuel usage at the K Reactors began in mid-1963. With the advent of the new fuel element concept, self-support development work in different areas was required. One such area was that of the supports, or rails, used on the elements. The initial self-support rail design on the elements, in order to meet production commitments, was only slightly modified from previous test models. These rails were identified as ''bridge rails.'' Development of the self-supports has continued and the first major modification, the ''arch-rails,'' of the original design is now ready for reactor testing.
