Description
The European Spallation Source (ESS) is a multi-disciplinary research facility based on neutron source located in Lund, Sweden. The ESS consists of three main parts: a linear proton accelerator, target and neutron science instruments. Target HVAC system plays a critical role in ensuring the process and safety of neutron production. Its functions include the following:
- Radiation Safety: the primary objective is to remove radioactive; toxic, explosive gases and aerosols formed during the interaction of neutrons with air and materials.
- Pressure Control and Confinement: the system maintains a negative pressure in work areas to prevent the spread of radioactive contaminants beyond the facility.
- Equipment Cooling: HVAC system removes heat loads from target components, preventing overheating.
- Environmental Control: maintaining a stable temperature is essential for the operation of high-precision equipment.
- Air Filtration: air passes through dust and contaminant filtration systems, protecting workers and equipment and ensuring clean air before being released into the environment.
Target HVAC system is designed in accordance with ISO 17873:2011 Nuclear facilities - Criteria for the design and operation of ventilation systems for nuclear installations other than nuclear reactors. All system components have been installed and are currently undergoing testing and commissioning. During testing and commissioning campaign our Target HVAC team encountered numerous challenges, particularly regarding systems balancing to ensure correct pressure cascade.
