| Ref No. & Title | : | Purchase of Cobalt-60 Source. Design, Supply, Installation, Commissioning, and Testing of New System for the Replacement of Existing Gamma Irradiator Equipment of IRPT on Turnkey Basis. |
| Reference Description | : | (i) Supply of Cobalt-60 Source. Manufacturer: NIITFA JSC and JSC ISOTOPE Country: RUSSIA Technical Specifications: (a) Activity for Each Pencil: 8000Ci to 14000Ci (b) Dimension of Each Pencil: F11 x 451 mm (c) Total Activity Required: 400 kCi (d) Type: Double Encapsulated (ii) Design, Supply, Installation, Testing and Commissioning of New System for the Replacement of Existing Gamma Irradiator Equipment of IRPT, BAEC. (a) Conveyor: Pneumatic Driven (b) Minimum Source Efficiency: 35% (c) DUR (Dose Uniformity Ratio): 1.32 – 2.00 (d) Specification of major equipment: Major parts are conveyor, Control system, and Safety interlock system. Main components and the specifications are as followed. (e) Conveyor: Conveyor includes the storage conveyor, Interim conveyor and source pass mechanism. The conveyor will be driven by compressed air cylinder and boxes side must change automatically. Transport system inside the irradiation room will be replaced with a rail-based pneumatic system utilizing boxes. A suitable radiation-resistant box movement system will be employed for lowest possible maintenance of the irradiator. Tote boxes will be transferred into and out of the irradiation room via ground-level-cable-driven trolley system. (f) Control System and Safety Interlock System. The system must ensure safe and efficient operation of the irradiator, traceable management of data and documentation of whole process and logic functional control based on PLC. Displays are organized in functional groups so that functions are easily located. Below items are recommended as a standard configuration. ? Photoelectric switches for personnel access, product entry and exit ports. ? Fixed radiation monitor. ? Valve lever for raising source. ? Key-switch for activating delay timer. ? Emergency pull cables ? Source status indicator ? Source down switch ? Rack anti-collusion device ? Smoke sensor ? Flow meter for ventilation system ? Removable roof plugs switch ? Pool water level indicator ? Power failure interlock ? Radiation signs and labels (g) Design of the Plant |
