Fluental is a drug sold in Italy. It's a combination of acetaminophen (paracetamol) and sobrelol, which is a mucolytic. Basically, it's a cold remedy. It is manufactured by Sanofi.
After looking (without result!) at loads of pages returned from a Bing search for BNCT, I hit upon searching for:
FLUENTAL moderator
The first reference I looked at was:
Use of TEPCs for characterising BNCT Beams
but there is no reference to the manufacturer.
However, the opening chapter of:
Chemical aspects on the final disposal of irradiated
reads:
The Boron Neutron Capture Therapy (BNCT) at VTT utilized the FiR 1 TRIGA reactor as a source for the neutron beam. The fast fission neutrons from the reactor needed to be slowed down to the epithermal energy range (0.5 eV–10 keV) prior to reaching the patient. The epithermal neutrons were produced in a block of FLUENTAL™ set between the the reactor and the patient. FLUENTAL™ is a patented material that has been developed and produced by VTT (Auterinen & Salmenhaara 2008, Savolainen et al. 2013). The composition of FLUENTAL™ is AlF3 (69 w-%), metallic aluminium (30 w-%) and LiF (1 w-%). The manufacturing process is based on a hot isostatic pressing technique, which results in a FLUENTAL™ product consisting of solid blocks with a density of 3 000 kg/m3. The decommissioning of the FiR 1 reactor leaves VTT with two options; to sell it abroad or to dispose of it together with the other decommissioning waste. At present, both options are considered and the final decision will be made at a later stage.
