Withdrawal characteristics of five major designs of fuel assembly nozzle were evaluated. Results of these tests contributed to development of the final FTR core design, comprising a nozzle with a single upper piston ring and a lower close-clearance region in an Inconel 718 receptacle liner. Testing in both the sodium environment and in air verified the choice of a chromium-plated fuel assembly nozzle to provide superior resistance to nozzle wear, and to preclude any damage to the long-life liner.
