METALS COMPARATOR TESTING OF HANFORD URANIUM SLUGS

摘要

It has been found that the Metals Comparator can effectively measure the extent to which a bare uranium slug has been transformed to e beta heat treated structure. The sensitivity and reliability of the method, as well as its simplicity and speed of performance, favor its use as a production test for routine inspection of bare slugs. The adjustments and conditions for optimum performance of the instrument are described. Acceptance specifications are given.nThe Metals Comparator cannot be applied satisfactorily to the testing of aluminum-canned slugs, however. Slight but acceptable variations associated with the jacketing affect the test results to such an extent that they tend to camouflage the effects of transformation differences.
