Neutrons for Science
Introducing this system reduced the number of purely ILL instruments to 25. There were 11 CRG instruments established,
9 of which included some time for ILL experiments. The first contracts of this type were made with the Paul Scherrer Institut (Switzerland) in 1994 for partial use of the D1A diffractometer and a triple axis spectrometer. Implementation of the CRGs has, in addition to the financial gains, allowed the ILL to function with the lower number of staff remaining after all the early retirements.
I have already mentioned the very negative reception of the partial withdrawal of the British. This placed the British deputy director in a difficult position. There was no British director between the departure of Peter Day in 1991 and the appointment of Colin Carlile in 2001 (after a period when he was deputy director). The return to having a British Director was made possible by a progressive increase in the British contribution (27% in 2000, 29% in 2001 and 32% in 2002) to 33% in 2003. This return was welcomed by everyone at the ILL.
8.3 Supply of enriched uranium
Another problem for the reactor111 arose at the same time. In
1992 the conditions for the export from USA of highly enriched uranium were modified by the Schumer Amendment. This stipulated that highly enriched uranium (which we recall can be used directly to make an atomic bomb) could only be exported for use in a research reactor if uranium with 20% enrichment would not allow the reactor to function at all. The buyer should ensure
