Study on LBLOCA of Qinshan Phase Ⅱ Nuclear Power Plant Project Loaded With Annular Fuel

The annular fuel that cooled internally and externally is a new PWR fuel which consists of two cladding and annular pellets. The annular fuel has more safety performance for new structure. Qinshan Phase Ⅱ Nuclear Power Plant project was selected to analyze large break loss of coolant accident (LBLOCA) as the reference plant. The results show that the plant loaded with the annular fuel is more safe than that loaded with the solid fuel during LBLOCA.
