The SPIDER experiment (located in Padova, Italy, as external facility to study the Ion Source for the HNB of ITER experiment) needs a dedicated Cooling Plant to remove up to 10 MW heat loads applied during the one hour pulses to the beam source, the beam dump/calorimeter and the power supplies. The total water flow rate necessary to remove the heat and guarantee the optimal control of temperatures is about 130 kg/s at full operational conditions. The plant is widespread over the whole PRIMA site area and is characterized by several physical inter- faces with the SPIDER experiment, the related power supplies and control system and finally with PRIMA buildings and civil plants. A well-equipped system of sensors and feed-back control system is also present to guarantee the correct performances of the plant during different operational phases. The paper deals with the installation and testing phases of the plant under execution during 2016, with particular emphasis on integration problems, electrical insulation, vibration issues for pumps, and finally the acceptance tests before integrated commissioning.

Abstract
The SPIDER experiment (located in Padova, Italy, as external facility to study the Ion Source for the HNB of ITER experiment) needs a dedicated Cooling Plant to remove up to 10 MW heat loads applied during the one hour pulses to the beam source, the beam dump/calorimeter and the power supplies. The total water flow rate necessary to remove the heat and guarantee the optimal control of temperatures is about 130 kg/s at full operational conditions. The plant is widespread over the whole PRIMA site area and is characterized by several physical inter- faces with the SPIDER experiment, the related power supplies and control system and finally with PRIMA buildings and civil plants. A well-equipped system of sensors and feed-back control system is also present to guarantee the correct performances of the plant during different operational phases. The paper deals with the installation and testing phases of the plant under execution during 2016, with particular emphasis on integration problems, electrical insulation, vibration issues for pumps, and finally the acceptance tests before integrated commissioning.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
