No CNS, but

UCN:                         A group around Werner Heil ( and Stephan Paul ( uses the TRIGA reactor (possibly in the pulsed mode) for testing successfully new methods of UCN-production (solid D2  and CD4) and UCN storage. An upgraded UCN source will be in operation from 2008 on at the radial channel D with its factor of 6 higher neutron flux.
