Design of Production test IP-243-A-6-FP, evaluation of X-8001 alloy aluminum components fabricated from cast blanks

摘要

The objective of this test is to determine the quality and erosion resistance of cape and cans produced from cast X-8001 alloy blanks through fabrication and irradiation of limited quantities in accordance with the testing procedure herein defined. Components which were fabricated from X-8001 alloy cast blanks have been subjected to rigorous out-of-reactor tests and have indicated equivalence or possible superiority to standard X-8001 alloy components. It is, therefore, proposed that; (1) six enriched charges of (0.94% U235) test material alternated with standard control material be irradiated; two to 500 MWD/T, and four to 800 MWD/T goal exposures in an old reactor, to compare corrosion resistance and (2) up to 240 charges of test enriched fuel elements be irradiated to normal variable goal exposure for enriched I&E in the same reactor, to further evaluate the performance of the components fabricated from cast blanks.
