1 Government of India Department of Atomic Energy Variable Energy Cyclotron Centre 1/AF,Bidhan Nagar, Kolkata-700 064 TECHNICAL REPORT / HISTORY SHEET. 1. Division: VECC, DAE, Kolkata – 700 064 2. Name of Work : Supply, fabrication and installation of lead (Pb) shielding blocks with MS shielding cover for SPECT trench in MCP. 3.History: DAE has proposed to implement the DAE Medical Cyclotron project through its units, namely, Variable Energy Cyclotron Centre (VECC), Kolkata and Board of Radiation and Isotope Technology (BRIT), Mumbai. The DAE Medical Cyclotron Facility is to be established in Kolkata for the following purposes: • Production of Single Photon Emission Computed Tomography (SPECT) isotopes like Ga-67, Tl-201 (optionally In-111, I-123) and Positron Emission Tomography (PET) isotope like F-18 (FDG) which are all be used in medical applications. • R & D purposes related to material science and ADSS. The cyclotron-produced radioisotopes will be used in nuclear imaging or therapy. This SPECT isotopes will be transferred from vaults to hot cell via trench. As the isotopes are radioactive and passes through the human occupancy area, the Lead (Pb) shielding is required for the trench. 4. Scope: Contractor’s scope of work include following – a) Supply and installation of good quality of lead (Pb) blocks confirming to IS27:1965 and IS2120:1962 standard. b) Fabrication, installation and fixing of the of the MS support and painted the MS support structure. c) 6 mm thick Checker plate supply and installation to maintain the floor level and to cover the lead blocks. The work should be carried out based on the reference drawings (MCP-SPECT-SHIELD-ASSY-07, MCP-SHIELDING-SPECT-01, MCP-SHIELDING-SPECT-02, MCP-SHIELDING-SPECT-03, MCP-SHIELDING-SPECT-04, MCP-SHIELDING-SPECT-05, MCP-SPECT-SHIELD-ASSY-06) suit to site basic and as per the direction of departmental engineer. 5. Estimated Cost: Rs. 38,50,000/- 6. Mode of operation: Through Contract. 7. Time of completion: 5 (Five) months sd/- sd/- User of the Facility Head of Section / Group 2 Government of India Department of Atomic Energy Variable Energy Cyclotron Centre 1/AF, Bidhannagar, Kolkata-700 064 Section : VECC, MCP, Kolkata Name of work: Supply, fabrication and installation of lead (Pb) shielding blocks with MS shielding cover for SPET trench in MCP.
