We designed and developed the CO2 circulators, or submerged
blowers, that provide the heat transfer in the Advanced Gas-cooled Reactors
(AGRs) and which in turn provide the bulk of the UK’s nuclear generated
electricity; units that once installed operate with no maintenance during plant
For gas reactors we also provided the centrifugal and axial fans used in the cooling
and other auxiliary systems.
For water cooled reactors, we supply the fans associated with
the various safety systems such as reactor building cooling in addition to other cooling and ventilation systems, and the completely leak tight diaphragm
compressors for radioactive gas leak recovery. Where these gases have to be
compressed to high pressure it is our compressors that are mainly preferred.
Our encapsulated blowers have been used in the auxiliary systems of
demonstration fusion reactors.
For reprocessing plants, specialised centrifugal fans are used for cell
cooling and diaphragm compressors for pressure testing. For decommissioning,
centrifugal fans are used for ventilation and cooling.
Howden's Burton Corblin® diaphragm compressors handle radioactive gases in their fully insulated compression chambers and serve nuclear power stations, laboratories and other applications where leakage is not an option.
