METHOD OF PREPARING PLATE-SHAPED HIGH-DENSITY LOW-ENRICHED URANIUM DISPERSION TARGET AND HIGH-DENSITY LOW-ENRICHED URANIUM TARGET PREPARED THEREBY

摘要

The present disclosure relates to a method of preparing a plate-shaped high-density low-enriched uranium dispersion target and high-density low- enriched uranium target prepared thereby. And the present disclosure relates to a method of preparing medical radioactive 99Mo by using the uranium target prepared by the foregoing method. According to an aspect of the present invention, there is provided a method of preparing a plate-shaped high- density low-enriched uranium dispersion target including: preparing a uranium alloy powder from a low-enriched uranium raw material including less than 1 wt% of one or more selected from the group consisting of aluminum (Al), silicon (Si), chromium (Cr), iron (Fe), and molybdenum (Mo) by using a centrifugal atomization method; mixing the prepared uranium alloy powder with an Al-Si alloy powder within a range of 40 vol% to 50 vol% to prepare a compact; and rolling the prepared compact.
