Our fans are used in the various safety systems such as reactor building cooling for the PWR plants. For reprocessing plants our specialized centrifugal fans are used for cell cooling and are again used in the decommissioning process for ventilation and cooling.
In PWR plants our completely leak tight diaphragm compressors are used for radioactive gas leak recovery as well as in the reprocessing plants for pressure testing. 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.
We have supplied safety related fans for reactor building cooling as well as submerged gas circulators. Diaphragm compressors are supplied for radioactive gas scavenging. Howden continues to be a leader in the development of submerged helium blowers complete with high speed drives and magnetic bearings.
To ensure the cooling down of the vessel and other structural materials during an accident scenario.
In the controlled area the ventilation system provides fresh air, evacuation of exhaust air, air flow, heating, and cooling. Fans also ensure a constant negative pressure with respect to the outside atmosphere, so there is constant air flow from the local low level radioactivity into the potentially more radioactive areas.
Fans linked to the Important For Safety system are designed to operate under both normal conditions and accidental events. Reliability of design and manufacturing is assured by Howden's efficient and strictquality management system.
Due to the capital cost and huge amount of loss of production, a nuclear power plant cannot afford to stop. Our fans meet the highest requirements of reliable design and quality to satisfy the operators' needs ofcontinuous and safe production of electricity.
These blowers are fully submerged in the process cooling gas, and provide the heat transfer in the advanced gas cooled reactors (AGR's)
PWR station: Radioactive gas leak recovery. Gas collected is compressed for storage.
Nuclear waste treatment. Diaphragm compressors for spent fuel reprocessing and recycling.
Howden cooling fans can form a key component of the cooling tower (where one exists).
Our lifelong aftercare service will supply original replacement parts, support you with maintenance and installation, and even train your own engineers in maintenance techniques. We keep detailed plant records almost indefinitely, and regularly supply spare parts for machinery over 50 years old.
