[en] A small hot facility wing has been built as an addition to the Isotope Laboratory at the Bandung Reactor Centre. The main feature is that the cell contains a 240-cm dia. rotating table which carries most of the equipment and delivers it to the operating position at the front of the cell or the maintenance port at the rear. Two large glass windows give a view of the whole cell and a master-slave manipulator is used. Hematite concrete was selected for the cell as the high density shielding material in consideration of its cost and availability. Further details of cell construction are discussed. (author)

[en] Gastight utility plugs for the shielding walls of hot cells are mainly used for the passage of mechanical actuating mechanisms, for electric cables, for the passage of liquid and gaseous media and for purposes of visual inspection. The plugs are normally inserted in steel or brass casings. The design requirements for such plugs are: (a) safe prevention of the contamination of the operating room located in front of the Hot Cell: (b) mutual replaceability of plugs (for example, a mechanical plug must be capable of replacement by an electric plug); (c) the radiation shield of the utility plugs must be equivalent to an 85 cm or 110 cm thick baryte concrete wall having a density of 3.5 t/m³; (d) excellent gastight properties are required in order to ensure that the vacuum underpressure of 10-15 mm H20 inside the Hot Cell cannot entrain air from the outside. A design solution which meets these requirements for a mechanical utility plug is described. (author)

[en] The Interim Examination and Maintenance (IEM) Cell is located within the Fast Flux Test Facility (FFTF) Reactor Containment Building. This cell is a complex vertical hot cell whose purpose is to process reactor experiments and to perform maintenance on reactor and refueling components. Because access to this very complex cell is limited, a mock-up called the IEM Training Facility (IEMTF) has been developed. The IEMTF provides the IEM cell with many valuable benefits. Four of these benefits are: (1) development of alternate processing methods; (2) hands-on evaluation of equipment problems; (3) a ready source of verified parts, and (4) training facilities for IEM Cell technicians
