  1. Nuclear Journal of Canada, 1987 Vol 1 No. 1, by R.I. Haines, D.G. Owen, and T. T. Vandergraaf, CNS, 1987-03-01. Doc type: Paper.
    Summary: The behaviour of technetium in the geosphere is important in nuclear fuel waste management studies because this manmade element has a long half-life and, under ambient conditions in the laboratory, is not readily sorbed on geological materials. Fourier transform infrared spectroscopy studies have shown conclusively that the reaction between TeO; and Fe304 at room temperature occurs via a surface reduction of TcO4 to TcO2, the latter being precipitated at the Fe304 surface. These results confirm that technetium can be contained effectively by magnetite in the geosphere, provided reducing conditions can be maintained.

  2. Nuclear Journal of Canada, 1987 Vol 1 No. 2, by F. Gonzalez and P. Spekkens, CNS, 1987-06-01. Doc type: Paper.
    Summary: The process by which bulk water solutes are concentrated under tubesheet sluuge piles in nuclear steam generators was investigated in the laboratory under simulated CANDU operating conditions. Concentration rates were found to depend on the tube heat flux and pile depth, although beyond a critical depth the concentration efficiency decreased.
