Irradiation Plan of DUPIC Fuel at HANARO

Abstract

DUPIC fuel is planned to start irradiation at HANARO in January 2000. Before the campaign of DUPIC he1 irradiation, preliminary irradiation of simulated DUPIC he1 started in July 1999. A mini-element of five pellets was designed and analyzed in the condition of HANARO. The performance of mini-element was carried out with modified material properties of the DUPIC pellet. In addition, the design of open-basket type capsule was analyzed. All those results satisfied the criteria of HANARO. According to the results of this irradiation, irradiation condition at HANARO will be fixed and the design of the fuel and capsule will be proved.
