IMMOBILIZATION OF KRYPTON BY INCORPORATION INTO A METALLIC MATRIX BY COMBINED ION IMPLANTATION AND SPUTTERING
A process has been devised at Harwell in which 85-Kr is immobilized as minute gas bubbles in a metal matrix. This technique offers an ideal form of containment, since only a small fraction of the gas will be released if the matrix is mechanically damaged and bubbles in metals are stable to high temperatures. Corrosion resistance can be provided by choosing a metal resistant to the environmental conditions. The matrix, therefore, offers suitable containment of the gas to satisfy the safety requirements for transport, storage and disposal. The main objective of this work was to design, build and operate a half-scale inactive pilot plant to demonstrate the process on a scale comparable with that envisaged for an industrial plant, to obtain operating information and to produce thick samples of gas filled deposit for assessment. The work so far has established the feasibility of incorporating krypton in a metallic matrix on a pilot plant scale. Initial tests have confirmed the advantages of the matrix material for containing krypton.
