Status on Radiation Processing in China Zhang Jinrong China Isotope & Radiation Corporation PBNC2016, Beijing

China Isotope & Radiation Corporation Overall China Isotope & Radiation Corporation Radiation Processing Industry Gamma Facilities and Accelerators Compare Gamma Facility and EB

Overall Radiation processing industry has made great progress in the past 30 years. 137 gamma radiation facilities design source loading capacity: 170 million curie actual source loading: about 70 million curie Annual sources demand of China: 11 million Ci Annual output of domestic cobalt-60 sources: 7 million Ci

EB facilities used in radiation processing 400 200 57 400 electron accelerators in 2015 increase 200% from 200 units (year 2007) and 700% from 57 units (year 2003)

Radiation Processing in Chemical Industry Main application crosslink of wire and cable , foaming material crosslink of heat-shrinkable material polymerization for paints grafting (battery membrane)

EB Facilities Application others Environment Sterilization 10% Chemical Heat Shrink Export Cable application The output value of radiation crosslinking wire and cable has more than RMB20 billion.

Radiation Processing Service The main radiation service: Food radiation: Irradiated food was 200 thousand tons per year, almost half of irradiated food in the world, 100% increase from year 2003 (100 thousand tons). Sterilization of healthcare products: Irradiation sterilization accounted for 20% of the whole healthcare sterilization products. (2) Contribution to GDP RMB25 billion in 2015 with Gamma ray and EB, 297% increase from year 2003 (6.3 billion)

China Isotope and Radiation Corporation (CIRC) CIRC is a specialized company in CNNC nuclear technology application industry. It has the whole industry chain of products and services with the core of isotope products and radiation processing. Chinese government qualified three companies for radiation facility design. CIRC owned two of them. CIRC has seven gamma radiation facilities.

China Isotope and Radiation Corporation (CIRC) Domestic cobalt-60 sources 7 million curie annually Qinshan Candu reactors from the beginning of 2010. reduced short supply and high prices of industrial cobalt-60 in China

Radiation Processing Industry Industry consolidation will be a trend and It should be based on the integration of industry group and industry chain. The world economy slowdown and radiation processing industry will be affected, but not too much. The people on healthy living requirements will continue to increase. The growth rate of industrial irradiation will continue to rise.

Radiation Processing Industry New areas of application of irradiation technology will continue to develop and practice. New development opportunities: Improvement of science and technology New products and new technology emerge Technological upgrading of existing products

Gamma Facilities and Accelerators Gamma facilities developed fast in recent years. About 10-15 new facilities were constructed annually. Gamma facilities have completed overall layout, thus the new construction of gamma facilities will reduce. During the thirteenth five-year plan period, the construction of new facilities will decrease. Annual new 2-3 facilities will be expected.

Gamma Facilities and Accelerators Co-60 Sources Price Cobalt source prices are impacted by the market and determined by supply and demand. Three suppliers: Canada, Russia and China The new gamma facilities reduced and the loading demand of existing facilities has not increased significantly in recent years. So the price of Co-60 Sources will be stable.

Compare Gamma Facility and EB (X-ray) Electron beam irradiation apparatus and gamma facilitiy are different; each has advantages and disadvantages. Electron beams and X-rays can not completely replace the cobalt-60 source, but the quantities of electron beams will be much larger than gamma facilities. If the efficiency of X-ray device improve significantly, prospects will be good in the future.

Compare Gamma Facility and EB (X-ray) Gamma facilities will not be eliminated as a whole. Unsafe and inefficient small facilities will shutdown. The overall amount of the gamma facilities will not increase too much, but the efficiency of the radiation industry will be improved. Gamma facilities and EB will be long-term coexistence on the Chinese market.
