Verification tests on nondestructive assay for $$^{238}$$U content in uranium-contaminated waste drums using $$gamma$$ method

Yokoyama, Kaoru; Sugitsue, Noritake; Muroi, Masayuki*; Suzuki, Yasuo*

Radioactive waste generated from nuclear fuel facilities must have the acceptance criterion of disposal. Although the $$gamma$$ ray measurement technique is expected as the measurement technique, the correction for the influences of the heterogeneous waste distribution was needed. Therefore, the computational technique using the $$gamma$$ ray of two energies emitted from $$^{238}$$U progeny nuclide ($$^{rm 234m}$$Pa) was developed, and verified the validity with simulated waste. As a result, the relative error was less than 20%, and detection limit was 1.2 Bq/g.
