sup 210 Po-Be start-up source rods for 300 MWe Qinshan Nuclear Power Plant

摘要

In order to perform the start-up of pressurized water reactor (PWR) for 300 MWe Qinshan Nuclear Power Plant, a pair of 'primary' source rods with (sup 210)Po-Be neutron sources were made successfully. The total neutron emission was (3.0 x 10(sup 8) +-5%) n/s (May 10, 1991). The dimensions of source rod were 10 mm in diameter and 3173 mm long. The research for source core ((sup 210)Po-Be source) and source rod technology are described. A new production line of source rod has been established and approved source rod technology has been used. All examinations (including neutron emission, surface contamination, helium leak rate, weld detection, dimension measurement, linearity inspection, etc.) showed that the quality of neutron source rods meets or exceeds the technical specifications of 'Inspecting and Accepting Outline of Primary Start-up Source Rods', prepared by the Qinshan Nuclear Power Plant and the Shanghai Institute of Nuclear Engineering Research and Design. The (sup 210)Po-Be neutron source rods to start-up pressurized water reactor of Qinshan Nuclear Power Plant were utilized. (Atomindex citation 26:050368)
