The fission product, 99Tc, presents significant challenges to the long-term disposal of nuclear waste due to its long half-life, high fission yield, and to the environmental mobility of pertechnetate (TcO4−), the stable Tc species in aerobic environments.

The fission yield of I131 has been investigated using improved extraction techniques and disintegration rate measurements. The value obtained for the fission yield is (3.1 ± 0.1)%. This is relative to a Ba140 reference fission yield of 6.1%. The half-life for I131 has been determined and found to be 8.05 ± 0.01 days.

Key Issues

Technetium is one of key issues in the treatment of radioactive liquid waste because of its long half-life in combination with high fission yield and its geochemical mobility. For the removal of Tc(VII) from water and concentrated alkaline solutions, 2-nitrophenyl octyl ether (NPOE) is a very effective extractant. In this paper we describe the application of supported liquid membranes (SLMs) impregnated with NPOE for the removal of Tc(VII) from these solutions by using 1.5 M HNO

The Absolute

The absolute fission yield of Ba140 in the thermal neutron fission of U235 has been determined to be (6.32 ± 0.24)%. The reaction B10(n, α)Li7 was used as a neutron monitor and the B10/B11 ratio determined mass spectrometrically before and after neutron bombardment. The Ba140 disintegration rate was determined using 4π counting techniques. The half-life of La140 has been found to be 40.31 ± 0.06 hr.

Direct Production

Fission of uranium yields Xe135 by two routes: direct production and production by the β-decay of I135. The amount produced directly (independent yield) has been measured by comparison with the amount produced from I135. The independent fission yield of Xe135 is found to be 2.7 ± 1.0% of the cumulative yield of I135. Assuming this latter quantity to be 5.6% of all fissions, the independent yield of Xe135 is ∼0.15%. The half-life of Xe135 has been measured as 9.13 ±.05 hr.
