INVITATION TO TENDER FOR THE CONCEPT PROPOSAL, DETAILED DESIGN AND INSTALLATION OF GLOVEBOX EXTRACT VENTILATION TO THE FUSION ROOM IN THE MATERIALS RESEARCH FACILITY AT CULHAM SCIENCE CENTRE

A new active ventilation system to support ongoing activities in MRF building within the Fusion room is required [1]. The system will comprise of the following: 1. A new dry glove box extract to support the proposed 11 glove boxes to be located in the Fusion Room. In addition, the existing red extract system in the facility will be coupled with the new glovebox extract system. Such that, in the event of a fan failure at either the red extract or glovebox extract, the other fan can deliver the duty of both the red extract and glovebox extract systems. 2. Integrate the control philosophy of the existing red extract fan and the glovebox extract to enable them to act as duty/ standby in the event of either of the fans failing. UKAEA have completed an option assessment which identifies that considerable advantages that can be gained by coupling the existing red extract system with the Glovebox extract system which will add complementary resilience in terms of duty/ standby for both the red extract and glove box systems. The glovebox extract shall be sited where the space for the provisional standby red extract fan is located, the ventilation control panel and inverters will be located within the space provision available for the standby red extract fan.
