Production of sealed radioactive sources
The idea of establishing a production facility for sealed sources of ionizing radiation based on the WWR-K reactor arose in INP as early as 2000. At that time the gas and oil industry was developing rapidly in Kazakhstan. Hand in hand with the burgeoning construction of gas and oil pipelines, came ever more demanding requirements for radiographic control, which, in most cases, required the use of sealed sources, mainly based on Iridium-192. With the increased demand for radionucleid sources, INP set about establishing a facility for the commercial production of iridium sources. For three years, the Institute, using its own resources, went ahead. It trained and certifi ed specialists, prepared and introduced technical documentation, acquired a welding facility and, in 2003, received a state license permitting it to manufacture sources. However, for full scale production it was essential to equip the production facility with modern equipment and to modernise the hot cells of the WWR-K reactor, where it was envisaged about 80% of all technical operations would be carried out. Thanks to the support of CNCP, market research was carried out and a business plan prepared for the future production of sealed radioactive sources. This was the first experience that INP scientists had of marketing. The results showed that there was demand in the Kazakhstan market not only for Iridium-192, but also for Antimony-124, Cobalt-60 and Thallium-204, which were previously imported from Russia, Poland and other countries. Currently, the main customers for sealed radioactive sources in Kazakhstan are:
Market research not only made it possible to decide on the range of sources to be provided, but also stimulated the interest of customers in additional services such as recharging defectoscopes, transport, and the safe storage of spent sources. The joint project, entitled “Production of sealed radioactive sources for Kazakhstan industry and medicine”, was launched, with funding from CNCP, on 1 November 2007. Repairs were carried out on the building, and a start was made with modernising the hot cells and fabricating, fitting out and testing the special equipment needed for atmospheric control and for production. Of the 24 positions to be created by the project, 20 had already been filled. After successful testing of prototypes, some tens of sources were manufactured and mounted, meanwhile, operations were set up for recharging defectoscopes, transport and the eventual safe storage of the isotopes concerned in a depository. A review of the results shows that, thanks to help from CNCP and the efforts of the staff of the Institute, full scale commercial production of radioactive sources together with the provision of a full complex of associated services «preparation – recharging – transportation – storage» has been made possible.
