## Notice

(Very) High Temperature Reactors ((V)HTR), High Temperature Gas-cooled Reactors (HTGR) or Pebble Bed Modular Reactor (PBMR) are variations of the same reactor design that has been marked as an important technology in moving towards Net Zero. These reactors all have key common features in the form of the graphite moderator and TRISO (Tri-structural ISOtropic, also known as Coated Particle Fuel (CPF)) fuel. As part of the UK government's CPF programme, UKNNL is working towards the production of graphite matrix material for use in TRISO fuel. To produce this material, phenolic resin, suitable solvents and graphite powders are mixed and kneaded until they become homogenous, typically for several hours at a controlled temperature. UKNNL are seeking a supplier to provide a kneader to support this material production. The kneader must be combined with a cold trap for vacuum drying of the solvent.
