Radiological environmental impact of large-size nuclear power fuel assembly manufacturing in China

This paper describes radiological environmental impact of large-sized nuclear power fuel assemblies manufacturing in China from 1994 to 2001. The results show that the maximum individual effective dose of the public around the site caused by radioactive effluents under normal operation is 7.26 x 10-4 mSv. The collective effective dose within radius of 80 km from 1994 to 2001 is 156.4 man·mSv and annual average 19.5 man·mSv. The contribution of airborne radioactive effluents to the collective effective dose is about 98.5% of the total. (authors)
